If something called “Project METERON” sounds to you like a sinister project involving astronauts, robots, the International Space Station, and artificial intelligence, I don’t blame you. Because that’s what it is (except for the sinister part.) In fact, the Meteron Project (Multi-Purpose End-to-End Robotic Operation Network) is not sinister at all, but a friendly collaboration between the European Space Agency (ESA) and the German Aerospace Center (DLR.)
The idea behind the project is to place an artificially intelligent robot here on Earth under the direct control of an astronaut 400 km above the Earth, and to get the two to work together.
“Artificial intelligence allows the robot to perform many tasks independently, making us less susceptible to communication delays that would make continuous control more difficult at such a great distance.” – Neil Lii, DLR Project Manager.
On March 2nd, engineers at the DLR Institute of Robotics and Mechatronics set up the robot called Justin in a simulated Martian environment. Justin was given a simulated task to carry out, with as few instructions as necessary. The maintenance of solar panels was the chosen task, since they’re common on landers and rovers, and since Mars can get kind of dusty.
The first test of the METERON Project was done in August. But this latest test was more demanding for both the robot and the astronaut issuing the commands. The pair had worked together before, but since then, Justin was programmed with more abstract commands that the operator could choose from.
American astronaut Scott Tingle issued commands to Justin from a tablet aboard the ISS, and the same tablet also displayed what Justin was seeing. The human-robot team had practiced together before, but this test was designed to push the pair into more challenging tasks. Tingle had no advance knowledge of the tasks in the test, and he also had no advance knowledge of Justin’s new capabilities. On-board the ISS, Tingle quickly realized that the panels in the simulation down here were dusty. They were also not pointed in the optimal direction.
This was a new situation for Tingle and for Justin, and Tingle had to choose from a range of commands on the tablet. The team on the ground monitored his choices. The level of complexity meant that Justin couldn’t just perform the task and report it completed, it meant that Tingle and the robot also had to estimate how clean the panels were after being cleaned.
“Our team closely observed how the astronaut accomplished these tasks, without being aware of these problems in advance and without any knowledge of the robot’s new capabilities,” says DLR engineer Daniel Leidner.
The next test will take place in Summer 2018 and will push the system even further. Justin will have an even more complex task before him, in this case selecting a component on behalf of the astronaut and installing it on the solar panels. The German ESA astronaut Alexander Gerst will be the operator.
If the whole point of this is not immediately clear to you, think Mars exploration. We have rovers and landers working on the surface of Mars to study the planet in increasing detail. And one day, humans will visit the planet. But right now, we’re restricted to surface craft being controlled from Earth.
What METERON and other endeavours like it are doing, is developing robots that can do our work for us. But they’ll be smart robots that don’t need to be told every little thing. They are just given a task and they go about doing it. And the humans issuing the commands could be in orbit around Mars, rather than being exposed to all the risks on the surface.
“Artificial intelligence allows the robot to perform many tasks independently, making us less susceptible to communication delays that would make continuous control more difficult at such a great distance,” explained Neil Lii, DLR Project Manager. “And we also reduce the workload of the astronaut, who can transfer tasks to the robot.” To do this, however, astronauts and robots must cooperate seamlessly and also complement one another.
That’s why these tests are important. Getting the astronaut and the robot to perform well together is critical.
“This is a significant step closer to a manned planetary mission with robotic support,” says Alin Albu-Schäffer, head of the DLR Institute of Robotics and Mechatronics. It’s expensive and risky to maintain a human presence on the surface of Mars. Why risk human life to perform tasks like cleaning solar panels?
“The astronaut would therefore not be exposed to the risk of landing, and we could use more robotic assistants to build and maintain infrastructure, for example, with limited human resources.” In this scenario, the robot would no longer simply be the extended arm of the astronaut: “It would be more like a partner on the ground.”
A great celebratory eruption accompanied the successful launch of SpaceX’s Falcon Heavy rocket in early February. That launch was a big moment for people who are thoughtful about the long arc of humanity’s future. But the Tesla Roadster that was sent on a long voyage in space aboard that rocket is likely carrying some bacterial hitch-hikers.
A report from Purdue University suggests that, though unlikely, the Roadster may be carrying an unwelcome cargo of Earthly bacteria to any destination it reaches. But we’re talking science here, and science doesn’t necessarily shy away from the unlikely.
“The load of bacteria on the Tesla could be considered a biothreat, or a backup copy of life on Earth.” – Alina Alexeenko, Professor of Aeronautics and Astronautics at Purdue University.
NASA takes spacecraft microbial contamination very seriously. The Office of Planetary Protection monitors and enforces spacecraft sterilization. Spreading Terran bacteria to other worlds is a no-no, for obvious reasons, so spacecraft are routinely sterilized to prevent any bacterial hitch-hikers. NASA uses the term “biological burden” to quantify how rigorously a spacecraft needs to be sterilized. Depending on a spacecraft’s mission and destination, the craft is subjected to increasingly stringent sterilization procedures.
If a craft is not likely to ever contact another body, then sterilization isn’t as strict. If the target is a place like Mars, where the presence of Martian life is undetermined, then the craft is prepared differently. When required, spacecraft and spacecraft components are treated in clean rooms like the one at Goddard Space Flight Center.
The clean rooms are strictly controlled environments, where staff wear protective suits, boots, hoodies, and surgical gloves. The air is filtered and the spacecraft are exposed to various types of sterilization. After sterilization, the spacecraft is handled carefully before launch to ensure it remains sterile. But the Tesla Roadster never visited such a place, since it’s destination is not another body.
The Tesla Roadster in space was certainly manufactured in a clean place, but there’s a big difference between clean and sterile. To use NASA’s terminology, the bacterial load of the Roadster is probably very high. But would those bacteria survive?
The atmosphere in space is most definitely hostile to life. The temperature extremes, the low pressure, and the radiation are all hazardous. But, some bacteria could survive by going dormant, and there are nooks and crannies in the Tesla where life could cling.
The Tesla is not predicted to come into contact with any other body, and certainly not Mars, which is definitely a destination in our Solar System that we want to protect from contamination. In fact, a more likely eventual destination for the Roadster is Earth, albeit millions of years from now. And in that case, according to Alina Alexeenko, a Professor of Aeronautics and Astronautics at Purdue University, any bacteria on the red Roadster is more like a back-up for life on Earth, in case we do something stupid before the car returns. “The load of bacteria on the Tesla could be considered a biothreat, or a backup copy of life on Earth,” she said.
But even if some bacteria survived for a while in some hidden recess somewhere on the Tesla Roadster, could it realistically survive for millions of years in space?
As far as NASA is concerned, length of time in space is one component of sterilization. Some missions are designed with the craft placed in a long-term orbit at the end of its mission, so that the space environment can eventually destroy any lingering bacterial life secreted away somewhere. Surely, if the Roadster does ever collide with Earth, and if it takes millions of years for that to happen, and if it’s not destroyed on re-entry, the car would be sterilized by its long-duration journey?
That seems to be the far more likely outcome. You never know for sure, but the space-faring Roadster is probably not a hazardous bio-threat, nor a back-up for life on Earth; those are pretty fanciful ideas.
Musk’s pretty red car is likely just a harmless, attention-grabbing bauble.
Geoscience researchers at Penn State University are finally figuring out what organic farmers have always known: digestive waste can help produce food. But whereas farmers here on Earth can let microbes in the soil turn waste into fertilizer, which can then be used to grow food crops, the Penn State researchers have to take a different route. They are trying to figure out how to let microbes turn waste directly into food.
There are many difficulties with long-duration space missions, or with lengthy missions to other worlds like Mars. One of the most challenging difficulties is how to take enough food. Food for a crew of astronauts on a 6-month voyage to Mars, and enough for a return trip, weighs a lot. And all that weight has to be lifted into space by expensive rockets.
Carrying enough food for a long voyage in space is problematic. Up until now, the solution for providing that food has been focused on growing it in hydroponic chambers and greenhouses. But that also takes lots of space, water, and energy. And time. It’s not really a solution.
“It’s faster than growing tomatoes or potatoes.” – Christopher House, Penn State Professor of Geosciences
What the researchers at Penn State, led by Professor of Geosciences Christopher House, are trying to develop, is a method of turning waste directly into an edible, nutritious substance. Their aim is to cut out the middle man, as it were. And in this case, the middle men are plants themselves, like tomatoes, potatoes, or other fruits and vegetables.
“We envisioned and tested the concept of simultaneously treating astronauts’ waste with microbes while producing a biomass that is edible either directly or indirectly depending on safety concerns,” said Christopher House, professor of geosciences, Penn State. “It’s a little strange, but the concept would be a little bit like Marmite or Vegemite where you’re eating a smear of ‘microbial goo.'”
The Penn State team propose to use specific microorganisms to turn waste directly into edible biomass. And they’re making progress.
At the heart of their work are things called microbial reactors. Microbial reactors are basically vessels designed to maximize surface area for microbes to populate. These types of reactors are used to treat sewage here on Earth, but not to produce an edible biomass.
“It’s a little strange, but the concept would be a little bit like Marmite or Vegemite where you’re eating a smear of ‘microbial goo.'” – Christopher House, Penn State Professor of Geosciences
To test their ideas, the researchers constructed a cylindrical vessel four feet long by four inches in diameter. Inside it, they allowed select microorganisms to come into contact with human waste in controlled conditions. The process was anaerobic, and similar to what happens inside the human digestive tract. What they found was promising.
“Anaerobic digestion is something we use frequently on Earth for treating waste,” said House. “It’s an efficient way of getting mass treated and recycled. What was novel about our work was taking the nutrients out of that stream and intentionally putting them into a microbial reactor to grow food.”
One thing the team discovered is that the process readily produces methane. Methane is highly flammable, so very dangerous on a space mission, but it has other desirable properties when used in food production. It turns out that methane can be used to grow another microbe, called Methylococcus capsulatus. Methylococcus capsulatus is used as an animal food. Their conclusion is that the process could produce a nutritious food for astronauts that is 52 percent protein and 36 percent fats.
“We used materials from the commercial aquarium industry but adapted them for methane production.” – Christopher House, Penn State Professor of Geosciences
The process isn’t simple. The anaerobic process involved can produce pathogens very dangerous to people. To prevent that, the team studied ways to grow microbes in either an alkaline environment or a high-heat environment. After raising the system pH to 11, they found a strain of the bacteria Halomonas desiderata that thrived. Halomonas desiderata is 15 percent protein and 7 percent fats. They also cranked the system up to a pathogen-killing 158 degrees Fahrenheit, and found that the edible Thermus aquaticus grew, which is 61 percent protein and 16 percent fats.
Their system is based on modern aquarium systems, where microbes live on the surface of a filter film. The microbes take solid waste from the stream and convert it to fatty acids. Then, those fatty acids are converted to methane by other microbes on the same surface.
Speed is a factor in this system. Existing waste management treatment typically takes several days. The team’s system removed 49 to 59 percent of solids in 13 hours.
This system won’t be in space any time soon. The tests were conducted on individual components, as proof of feasibility. A complete system that functioned together still has to be built. “Each component is quite robust and fast and breaks down waste quickly,” said House. “That’s why this might have potential for future space flight. It’s faster than growing tomatoes or potatoes.”
In the past decade, the rate at which extra-solar planets have been discovered and characterized has increased prodigiously. Because of this, the question of when we might explore these distant planets directly has repeatedly come up. In addition, the age-old question of what we might find once we get there – i.e. is humanity alone in the Universe or not? – has also come up with renewed vigor.
These questions have led to a number of interesting and ambitious proposals. These include Project Blue, a space telescope which would directly observe any planets orbiting Alpha Centauri, and Breakthrough Starshot – which aims to send a laser-driven nanocraft to Alpha Centauri in just 20 years. But perhaps the most daring proposal comes in the form of Project Genesis, which would attempt to seed distant planets with life.
This proposal was put forth by Dr. Claudius Gros, a theoretical physicist from the Institute for Theoretical Physics at Goethe University Frankfurt. In 2016, he published a paper that described how robotic missions equipped with gene factories (or cryogenic pods) could be used to distribute microbial life to “transiently habitable exoplanets – i.e. planets capable of supporting life, but not likely to give rise to it on their own.
Not long ago, Universe Today wrote about Dr. Gros’ recent study where he proposed using a magnetic sail to slow down an interstellar spacecraft. We were fortunate to catch up with Dr. Gros again and had a chance to ask him about Project Genesis. You can find our Q&A below, and be sure to check out his seminal paper that describes this project – “Developing Ecospheres on Transiently Habitable Planets: The Genesis Project“.
What is the purpose of Project Genesis?
Exoplanets come in all sizes, temperatures and compositions. The purpose of the Genesis project is to offer terrestrial life alternative evolutionary pathways on those exoplanets that are potentially habitable but yet lifeless. The basic philosophy of most scientists nowadays is that simple life is common in the universe and complex life is rare. We don’t know that for sure, but at the moment, that is the consensus.
If you had good conditions, simple life can develop very fast, but complex life will have a hard time. At least on Earth, it took a very long time for complex life to arrive. The Cambrian Explosion only happened about 500 million years ago, roughly 4 billion years after Earth was formed. If we give planets the opportunity to fast forward evolution, we can give them the chance to have their own Cambrian Explosions.
What worlds would be targeted?
The prime candidates are habitable “oxygen planets” around M-dwarfs like TRAPPIST-1. It is very likely that the oxygen-rich primordial atmosphere of these planets will have prevented abiogenesis in first place, that is the formation of life. Our galaxy could potentially harbor billions of habitable but lifeless oxygen planets.
Nowadays, astronomers are looking for planets around M-stars. These are very different from planets around Sun-like stars. Once a star forms, it takes a certain amount of time to contract to the point where fusion begins, and it starts to produce energy. For the Sun, this took 10 million years, which is very fast. For stars like TRAPPIST-1, it would take 100 million to 1 billion years. Then they have to contract to dissipate their initial heat.
The planets around TRAPPIST-1 would have been very hot, because the star was very hot for a long time. All the water that was in their stratospheres, the UV radiation would have disassociated it into hydrogen and oxygen – the hydrogen escaped, and the oxygen remained. All surveys have showed that they have oxygen atmospheres, but this is the product of chemical disassociation and not from plants (as with Earth).
There’s a good chance that oxygen planets are sterile, because oxygen planets eat up prebiotic conditions. We believe there may be billions of oxygen planets in our galaxy. They would have no life, and complex life needs oxygen. In science fiction, you have all these planets that look alike. We could imagine that in half a billion years, we could have this because we seeded oxygen planets (only we couldn’t travel there quickly since we have no FTL).
What kind of organisms would be sent?
The first wave would consist of unicellular autotrophs. That is photo-synthesizing bacteria, like cyanobacteria, and eukaryotes (the cell type making up all complex life, that is animals and plants). Heterotrophs would follow in a second stage, organisms that feed on other organisms and can only exist after autotrophs exist and take root.
How would these organisms be sent?
That depends on the technology. If it can advance, we can miniaturize a gene factory. In principle, nature is a miniature gene factory. Everything we want to produce is very small. If it’s possible that would be the best option. Send in a gene bank, and then select the most optimal organism to send down. If that is not possible, you would have to have frozen germs. In the end, it depends on what would be the technically available.
You could also send in synthetic life. Synthetic biology is a very active research field, which involves reprogramming the genetic code. In science fiction, you have alien life with a different genetic code. Today, people are trying to produce this here on Earth. The end goal is to have new life forms that are based on a different code. This would be very dangerous on Earth, but on a far-distant planet, it would be beneficial.
What if these worlds are not sterile?
Genesis is all about life, not destroying life, so we’d want to avoid that. The probes would have to go into orbit, so we are pretty sure that from orbit, we could detect complex life on the surface. The Genesis Project was intended for planets that are not habitable for eternity. Earth is habitable for billions of years, but we are not sure about habitable exoplanets.
Exoplanets come in all kinds of sized, temperatures, and habitabilities. Many of these planets will only be habitable for some time, maybe 1 billion years. Life there will not have time to evolve into complex life forms. So you have a decision: leave them like they are, or take a chance at developing complex life there.
Some believe that all bacteria are worth saving. On Earth, there is no protection for bacteria. But bacteria living on different planets are treated differently. Planetary protection, why do we do that? So we can study the life, or for the sake of protecting life itself? Mars most likely had life at one time, but now not, except for maybe a few bacteria. Still, we plan manned missions to Mars, which means planetary protection is off. It’s a contradiction.
I am very enthusiastic about finding life, but what about the planets where we don’t find life? This offers the possibility about doing something about it.
Could humanity benefit from this someday (i.e. colonize “seeded” planets)?
Yes and no. Yes, because nothing would keep our decedents (or any other intelligence living on Earth by then), to visit Genesis planets in 10-100 million years (the minimal time for the life initially seeded to fully unfold). No, because the involved time spans are so long, that it is not rational to speak of a ‘benefit’.
How soon could such a mission be mounted?
Genesis probes could be launched by the same directed-energy launch system planned for the Breakthrough Starshot initiative. Breakthrough Starshot aims to send very fast, very small, very light probes of about 1 gram to another star system. The same laser technology could send something more massive, but slower. Slow is relative, of course. So the in the end it depends on what is optimal.
The magnetic sail paper I recently wrote was a sample mission to show that it was possible. The probe would be about the size of a car (1 tonne) and would travel at a speed of about 1000 km/s – slow for interstellar travel relative to speed of light, but fast for Earth. If you reduce the velocity by a factor of 100, the mass you can propel is 10,000 heavier. You could accelerate a 1-tonne Genesis Probe and it would still fit into the layout of Breakthrough Starshot.
Therefore, the launch facility could see dual use and you wouldn’t need to build something new. Once that is in place one would need to test the magnetic sail. A realistic time span would hence be in the 50-100 years window.
What counter-arguments are there against this?
There are three main lines of counter-arguments. The first is the religious counter-argument, which says that humanity should not play God. The Genesis project is however not about creating life, but to give life the possibility to further develop. Just not on Earth, but elsewhere in the cosmos.
The second is the Planetary protection argument, which argues that we should not interfere. Some people objecting to the Genesis Project cite the ‘first directive’ of the Star Trek TV series. The Genesis Project fully supports planetary protection of planets which harbor complex life and of planets on which complex life could potentially develop in the future. The Genesis project will target only planets on which complex life could not develop on its own.
The third argument is about the lack of benefit to humanity. The Genesis Project is expressively not for human benefit. It is reasonable to argue, from the perspective of survival, that the ethical values of a species (like humanity) has to put the good of the species at the center. Ethical is therefore “what is good for our own species”. Spending a large amount of money on a project, like the Genesis Project, which is expressively not for the benefit of our own species, would then be unethical.

Our thanks go out to Dr. Gros for taking the time to talk to us! We hope to hear more from him in the future and wish him the best of luck with Project Genesis.
NASA and SpaceX have jointly decided to move forward with the Dragon CRS-13 cargo blastoff apparently because the mission does not involve use of the problematical payload fairing that halted last weeks planned Falcon 9 launch with the rocket and the mysterious Zuma payload.
Zuma was ready and waiting at pad 39A for the GO to launch that never came.
Then after a series of daily delays SpaceX ultimately announced a ‘stand down’ for super secret Zuma at pad 39A on Friday, Nov. 17, for the foreseeable future.
Since SpaceX’s gumdrop shaped Dragon cargo freighter launches as a stand alone aerodynamically shielded spacecraft atop the Falcon 9, it does not require additional protection from atmospheric forces and friction housed inside a nose cone during ascent to orbit unlike satellites with many unprotected exposed surfaces, critical hardware and delicate instruments.
Thus Dragon is deemed good to go since there currently appear to be no other unresolved technical issues with the Falcon 9 rocket.
“NASA commercial cargo provider SpaceX is targeting its 13th commercial resupply services mission to the International Space Station for no earlier than 2:53 p.m. EST Monday, Dec. 4,” NASA announced on the agency blog and social media accounts.
But the targeted Dec 4 liftoff from Space Launch Complex 40 on Cape Canaveral Air Force Station, FL, was cast in doubt after SpaceX disclosed the payload fairing issue related launch delay on Friday.
Since last week SpaceX engineers have been busy taking the time to carefully scrutinize all the pertinent fairing data before proceeding with the top secret Zuma launch.
“We have decided to stand down and take a closer look at data from recent fairing testing for another customer,” said SpaceX spokesman John Taylor last Friday.
All of SpaceX’s launches this year from Florida’s Spaceport have taken place from NASA’s historic Launch Complex-39A at the Kennedy Space Center.
Pad 39A became SpaceX’s only operational Florida Space Coast launch pad following a catastrophic launch pad accident last year on Sept. 1, 2016 that took place during a routine fueling test that suddenly ended in a devastating explosion and fire that completely consumed the Falcon 9 rocket and Amos-6 payload and heavily damaged the pad and support infrastructure.
Since the Amos-6 accident workers raced to finish refurbishments to NASA’s long dormant pad 39A to transform into operational status and successfully launched a dozen missions this year.
Simultaneously additional crews have been hard at work to repair damaged pad 40 so that flights can resume there as soon as possible for the bulk of NASA, commercial and military contracted missions.
The Dragon CRS-13 mission was recently announced as the maiden mission for the reopening of pad 40.
Altogether Dragon CRS-13 will count as the fourth SpaceX Dragon liftoff of 2017.
The 20-foot high, 12-foot-diameter Dragon CRS-13 vessel will carry about 3 tons of science and supplies to the orbiting outpost and stay about 4 weeks.
It will be a reused Dragon that previously flew on the CRS-6 mission.
“The Dragon [CRS-13] spacecraft will spend about a month attached to the space station,” NASA said.
The prior Dragon CRS-12 resupply ship launched from pad 39A on Aug. 14, 2017 from KSC pad 39A and carried more than 6,400 pounds ( 2,900 kg) of science experiments and research instruments, crew supplies, food water, clothing, hardware, gear and spare parts to the million pound orbiting laboratory complex.
Dragon CRS-9 was the last ISS resupply mission to launch from pad 40 on July 18, 2016.
The recently arrived Orbital ATK Cygnus cargo ship is expected to depart the station from the Earth facing Unity node on Dec. 3 to make way for Dragon’s berthing at the Harmony node.
Watch for Ken’s continuing onsite coverage of SpaceX CRS-13, Zuma and KoreaSat-5A & Orbital ATK OA-8 Cygnus and NASA and space mission reports direct from the Kennedy Space Center and Cape Canaveral Air Force Station, Florida.
Stay tuned here for Ken’s continuing Earth and Planetary science and human spaceflight news.
The Orbital ATK Cygnus spacecraft was christened the S.S. Gene Cernan and named in honor of NASA’s Apollo 17 lunar landing commander; Gene Cernan.
Among the goodies delivered by the newly arrived S.S. Gene Cernan Cygnus OA-8 supply run to resident the crew of six astronauts and cosmonauts from the US, Russia and Italy are ice cream, pizza and presents for the holidays. They are enjoying the fruits of the earthy labor of thousands of space workers celebrating the mission’s success.
The journey began with the flawless liftoff of the two stage Antares rocket shortly after sunrise Sunday at 7:19 a.m. EST, Nov. 12, rocket from Pad-0A at NASA’s Wallops Flight Facility in Virginia.
Check out the expanding gallery of launch imagery and videos captured by this author and several space colleagues of Antares prelaunch activities around the launch pad and through Sunday’s stunningly beautiful sunrise blastoff.
After a carefully choreographed series of intricate thruster firings to raise its orbit in an orbital pursuit over the next two days, the Cygnus spacecraft on the OA-8 resupply mission for NASA arrived in the vicinity of the orbiting research laboratory.
Expedition 53 Flight Engineer Paolo Nespoli of ESA (European Space Agency) assisted by NASA astronaut Randy Bresnik then deftly maneuvered the International Space Station’s 57.7-foot-long (17.6 meter-long) Canadarm2 robotic arm to grapple and successfully capture the Cygnus cargo freighter at 5:04 a.m., Tuesday Nov. 14.
The station was orbiting 260 statute miles over the South Indian Ocean at the moment Nespoli grappled the S.S. Gene Cernan Cygnus spacecraft with the Canadian-built robotic arm.
Ground controllers at NASA’s Mission Control at the Johnson Space Center in Texas, then maneuvered the arm and robotic hand grappling Cygnus towards the exterior hull and berthed the cargo ship at the Earth-facing port of the stations Unity module.
The berthing operation was completed at 7:15 a.m. after all 16 bolts were driven home for hard mating as the station was flying 252 miles over the North Pacific in orbital night.
The Cygnus spacecraft dubbed OA-8 is Orbital ATK’s eighth contracted cargo resupply mission with NASA to the International Space Station under the unmanned Commercial Resupply Services (CRS) program to stock the station with supplies on a continuing and reliable basis.
Altogether over 7,400 pounds of science and research, crew supplies and vehicle hardware launched to the orbital laboratory and its crew of six for investigations that will occur during Expeditions 53 and 54.
The S.S. Gene Cernan manifest includes equipment and samples for dozens of scientific investigations including those that will study communication and navigation, microbiology, animal biology and plant biology. The ISS science program supports over 300 ongoing research investigations.
Apollo 17 was NASA’s final lunar landing mission. Gere Cernan was the last man to walk on the Moon.
Among the experiments flying aboard Cygnus are the coli AntiMicrobial Satellite (EcAMSat) mission, which will investigate the effect of microgravity on the antibiotic resistance of E. coli, the Optical Communications and Sensor Demonstration (OCSD) project, which will study high-speed optical transmission of data and small spacecraft proximity operations, the Rodent Research 6 habitat for mousetronauts who will fly on a future SpaceX cargo Dragon.
Cygnus will remain at the space station until Dec. 4, when the spacecraft will depart the station and release 14 CubeSats using a NanoRacks deployer, a record number for the spacecraft.
It will then be commanded to fire its main engine to lower its orbit and carry out a fiery and destructive re-entry into Earth’s atmosphere over the Pacific Ocean as it disposes of several tons of trash.
The Cygnus OA-8 manifest includes:
Crew Supplies 2,734.1 lbs. / 1,240 kg
Science Investigations 1631.42 lbs. / 740 kg
Spacewalk Equipment 291.0 lbs. / 132 kg
Vehicle Hardware 1,875.2 lbs. / 851 kg
Computer Resources 75.0 lbs. / 34 kg
Total Cargo: 7,359.0 lbs. / 3,338 kg
Total Pressurized Cargo with Packaging: 7,118.7 lbs. / 3,229 kg
Unpressurized Cargo (NanoRacks Deployer): 240.3 lbs. / 109 kg
Under the Commercial Resupply Services-1 (CRS-1) contract with NASA, Orbital ATK will deliver approximately 66,000 pounds (30,000 kilograms) of cargo to the space station. OA-8 is the eighth of these missions.
The Cygnus OA-8 spacecraft is Orbital ATK’s eighth contracted cargo resupply mission with NASA to the International Space Station under the unmanned Commercial Resupply Services (CRS) program to stock the station with supplies on a continuing basis.
Beginning in 2019, the company will carry out a minimum of six cargo missions under NASA’s CRS-2 contract using a more advanced version of Cygnus.
Watch for Ken’s continuing Antares/Cygnus mission and launch reporting from on site at NASA’s Wallops Flight Facility, VA during the launch campaign.
Stay tuned here for Ken’s continuing Earth and Planetary science and human spaceflight news.
Soon thereafter at 5:04 a.m., Expedition 53 Flight Engineer Paolo Nespoli of ESA (European Space Agency) assisted by NASA astronaut Randy Bresnik successfully captured Orbital ATK’s Cygnus cargo freighter using the International Space Station’s 57.7-foot-long (17.6 meter-long) Canadarm2 robotic arm.
The station was orbiting 260 statute miles over the South Indian Ocean at the moment Nespoli grappled the S.S. Gene Cernan Cygnus spacecraft with the Canadian-built robotic arm.
Nespoli and Bresnik were working at a robotics work station inside the seven windowed domed Cupola module that offers astronauts the most expansive view outside to snare Cygnus with the robotic arms end effector.
The Cygnus cargo freighter – named after the last man to walk on the Moon – reached its preliminary orbit nine minutes after blasting off early Sunday atop the upgraded 230 version of the Orbital ATK Antares rocket from NASA’s Wallops Flight Facility in Virginia.
The flawless liftoff of the two stage Antares rocket took place shortly after sunrise Sunday at 7:19 a.m. EST, Nov. 12, rocket from Pad-0A at NASA’s Wallops Flight Facility in Virginia.
Sunday’s spectacular Antares launch delighted spectators – but came a day late due to a last moment scrub on the originally planned Veteran’s Day liftoff, Saturday, Nov. 11, when a completely reckless pilot flew below radar into restricted airspace just 5 miles away from the launch pad – forcing a sudden and unexpected halt to the countdown under absolutely perfect weather conditions.
After a carefully choreographed series of intricate thruster firings to raise its orbit over the next two days, the Cygnus spacecraft on the OA-8 resupply mission for NASA arrived in the vicinity of the orbiting research laboratory.
With Cygnus firmly in the grip of the robots hand, ground controllers at NASA’s Mission Control at the Johnson Space Center in Texas, maneuvered the arm towards the exterior hull and berth the cargo ship at the Earth-facing port of the stations Unity module.
1st stage capture was completed at 7:08 a. EST Nov 14.
After driving in the second stage gang of bolts, hard mate and capture were completed at 7:15 a.m.
The station was flying 252 miles over the North Pacific in orbital night at the time of berthing.
The Cygnus spacecraft dubbed OA-8 is Orbital ATK’s eighth contracted cargo resupply mission with NASA to the International Space Station under the unmanned Commercial Resupply Services (CRS) program to stock the station with supplies on a continuing and reliable basis.
NASA TV provided live coverage of the rendezvous and grappling.
Including Cygnus there are now five visiting vehicle spaceships parked at the space station including also the Russian Progress 67 and 68 resupply ships and the Russian Soyuz MS-05 and MS-06 crew ships.
Cygnus will remain at the space station until Dec. 4, when the spacecraft will depart the station and deploy several CubeSats before its fiery re-entry into Earth’s atmosphere as it disposes of several tons of trash.
On this flight, the Cygnus OA-8 spacecraft is jam packed with its heaviest cargo load to date!
Altogether over 7,400 pounds of science and research, crew supplies and vehicle hardware launched to the orbital laboratory and its crew of six for investigations that will occur during Expeditions 53 and 54.
The S.S. Gene Cernan manifest includes equipment and samples for dozens of scientific investigations including those that will study communication and navigation, microbiology, animal biology and plant biology. The ISS science program supports over 300 ongoing research investigations.
Among the experiments flying aboard Cygnus are the coli AntiMicrobial Satellite (EcAMSat) mission, which will investigate the effect of microgravity on the antibiotic resistance of E. coli, the Optical Communications and Sensor Demonstration (OCSD) project, which will study high-speed optical transmission of data and small spacecraft proximity operations, the Rodent Research 6 habitat for mousetronauts who will fly on a future SpaceX cargo Dragon.
Cernan was commander of Apollo 17, NASA’s last lunar landing mission and passed away in January at age 82. He set records for both lunar surface extravehicular activities and the longest time in lunar orbit on Apollo 10 and Apollo 17.
Under the Commercial Resupply Services-1 (CRS-1) contract with NASA, Orbital ATK will deliver approximately 66,000 pounds (30,000 kilograms) of cargo to the space station. OA-8 is the eighth of these missions.
The Cygnus OA-8 spacecraft is Orbital ATK’s eighth contracted cargo resupply mission with NASA to the International Space Station under the unmanned Commercial Resupply Services (CRS) program to stock the station with supplies on a continuing basis.

NASA WALLOPS FLIGHT FACILITY, VA – An Orbital ATK Antares rocket successfully blasted off this morning, Sunday, Nov. 12, from the eastern shore of Virginia on a NASA contracted mission bound for the International Space Station (ISS) carrying a Cygnus cargo ship loaded with nearly 4 tons of vital science and supplies.
The two stage Antares rocket launched flawlessly shortly sunrise Sunday at 7:19 a.m. EST, Nov. 12 on an upgraded version of the Antares rocket from Pad-0A at NASA’s Wallops Flight Facility in Virginia carrying the Cygnus resupply spacecraft named in honor of Gene Cernan, the last man to walk on the Moon.
The launch came a day late due to a last moment scrub on the originally planned Veteran’s Day liftoff, Saturday, Nov. 11, when a reckless pilot flew below radar into restricted airspace just 5 miles away from the launch pad – forcing a sudden and unexpected halt to the countdown under absolutely perfect weather conditions.
Finally the rocket roared off the pad Sunday under cloudy skies – to the delight of a spectators, with a brilliant flash of light. Slowly at first and then accelerating almost straight up before arcing over just slightly in a southeasterly direction and soon disappearing into the thick clouds. In fact it was so load that local residents told me their windows and houses shook and rattled.
Saturday’s sudden scrub disappointed tens of thousands of spectators who had gathered around the East coast launch region and beyond for a rare chance to see the launch of a powerful rocket on a critical cargo delivery mission for NASA conducted the benefit of the six person crew serving on the station to advance science for all of humanity.
The pilot may have intentionally flown the plane low enough to avoid detection so he could take photos for profit.
As a result of this extremely serious violation of flight rules which raises significant safety and base security issues the FAA and NASA are now undertaking an intense review of rules after the repeated serious incursions by planes and boats into exclusion zones during launches, and what penalties and fines should be applied.
The Cygnus spacecraft dubbed OA-8 is Orbital ATK’s eighth contracted cargo resupply mission with NASA to the International Space Station under the unmanned Commercial Resupply Services (CRS) program to stock the station with supplies on a continuing and reliable basis.
“Today’s successful launch of the OA-8 Cygnus on our Antares launch vehicle once again demonstrates the reliability of Orbital ATK’s hardware along with our commitment to deliver critical cargo to astronauts on the International Space Station,” said Frank Culbertson, President of Orbital ATK’s Space Systems Group.
“Soon, Cygnus will rendezvous with the space station to deliver valuable scientific experiments, hardware and crew supplies to the orbiting platform. On this mission, Cygnus will again display its flexibility as an in-orbit science platform by supporting experiments to be performed inside the cargo module while attached to the space station. We are proud to dedicate this mission to Apollo astronaut Gene Cernan and his family and look forward to celebrating the OA-8 contributions to science in his name.”
After a two day orbital chase the S.S. Gene Cernan will arrive in the vicinity of the space station early Tuesday, Nov. 14. Cygnus will be grappled by Expedition 53 astronaut Paolo Nespoli of ESA (European Space Agency) of Italy at approximately 4:50 a.m. EST on November 14 using the space station’s robotic arm. He will be assisted by NASA astronaut Randy Bresnik.
NASA TV will provide live coverage of the rendezvous and grappling.
Cygnus will remain at the space station until Dec. 4, when the spacecraft will depart the station and deploy several CubeSats before its fiery re-entry into Earth’s atmosphere as it disposes of several tons of trash.
The 14 story tall commercial Antares rocket launched for only the second time in the upgraded 230 configuration – powered by a pair of the new Russian-built RD-181 first stage engines.
The rocket performed flawlessly said Kurt Eberly, Orbital ATK deputy program manager for Antares, during the post launch briefing at NASA Wallops.
There was only a slight over performance of the Castor XL solid fueled second stage, which was all to the good – as occurred during the first launch of the upgraded Antares a year ago in October 2016 on the OA-5 resupply mission.
Indeed the overperformance of the second stage may allow Orbital ATK to load the Cygnus with an even heavier cargo load than previously foreseen.
On this flight,the Cygnus OA-8 spacecraft is jam packed with its heaviest cargo load to date!

NASA WALLOPS FLIGHT FACILITY, VA – The Orbital ATK Antares rocket is all set for a breakfast time blastoff from the commonwealth of Virginia to the International Space Station for NASA with a Cygnus cargo freighter named in honor of Gene Cernan, the last man to walk on the Moon.
The Antares launch is targeted for 7:37 a.m. EST on Saturday, Nov. 11, 2017 carrying the S.S. Gene Cernan resupply vessel that’s loaded with nearly four tons of science and supplies for the six person crew serving on the station.
Antares liftoff with the Cygnus spaceship also known as OA-8 will take place from launch Pad-0A at NASA’s Wallops Flight Facility located along the eastern shore of Virginia.
The rocket was integrated with the Cygnus OA-8 supply ship this week and rolled out to the launch pad starting around 1 a.m. EST this morning Thursday, Nov. 9.
The Cygnus OA-8 spacecraft is Orbital ATK’s eighth contracted cargo resupply mission with NASA to the International Space Station under the unmanned Commercial Resupply Services (CRS) program to stock the station with supplies on a continuing basis.
The upgraded Antares rocket was erected into the vertical position and is now poised for liftoff early Saturday morning.
Tens of millions of spectators could potentially witness the launch with their own eyeballs since NASA’s Wallops Flight Facility is located within a short driving distance of the most heavily populated area of the United States along the eastern seaboard.
Since Saturdays weather forecast is quite favorable at this time this could be your chance to watch an exciting launch on a critical mission for NASA with your family or friends.
See detailed visibility map below.
But be aware that temperatures will be rather chilly, setting record or near record lows in the 20s throughout the Northeast and Atlantic coast states.
If you are wondering whether to watch, consider that Antares launches are infrequent.
The last Antares launch from Wallops took place a year ago on 23 October 2016 for the OA-5 cargo resupply mission to the ISS for NASA.
If you can’t watch the launch in person, you can always follow along via NASA’s live coverage.
Live launch coverage will begin at 7 a.m. Saturday on NASA Television and the agency’s website: www.nasa.gov
The launch window opens at 7:37 a.m. EST.
The windows runs for five minutes extending to 7:42 a.m. EST.
The 14 story tall commercial Antares rocket will launch for only second first time in the upgraded 230 configuration – powered by a pair of the new Russian-built RD-181 first stage engines.
The Cygnus spacecraft will deliver over 7,400 pounds of science and research, crew supplies and vehicle hardware to the orbital laboratory and its crew of six for investigations that will occur during Expeditions 53 and 54.
The S.S. Gene Cernan manifest includes equipment and samples for dozens of scientific investigations including those that will study communication and navigation, microbiology, animal biology and plant biology. The ISS science program supports over 250 ongoing research investigations.
Among the science: “Cygnus will carry several CubeSats that will conduct a variety of missions, from technology demonstrations of laser communication and increased data downlink rates to an investigation to study spaceflight effects on bacterial antibiotic resistance. Other experiments will advance biological monitoring aboard the station and look at various elements of plant growth in microgravity that may help inform plant cultivation strategies for future long-term space missions. The spacecraft will also transport a virtual reality camera to record a National Geographic educational special on Earth as a natural life-support system.”
“Orbital ATK is proud to name the OA-8 Cygnus Cargo Delivery Spacecraft after former astronaut Eugene “Gene” Cernan,” said Orbital ATK.
“As the last human to step foot on the moon, Cernan set records for both lunar surface extravehicular activities and longest time in lunar orbit, paving the way for future human space exploration. He died in January 2017.”
The last Cygnus was named the S.S. John Glenn, first American to orbit Earth, and launched atop a ULA Atlas V in March 2017.
After a two day orbital chase Cygnus will reach the stations vicinity on Monday, Nov. 13.
“Expedition 53 Flight Engineers Paolo Nespoli of ESA (European Space Agency) and Randy Bresnik of NASA will use the space station’s robotic arm to capture Cygnus at about 5:40 a.m. NASA TV coverage of rendezvous and capture will begin at 4:15 a.m.,” said NASA.
“After Canadarm2 captures Cygnus, ground commands will be sent to guide the station’s robotic arm as it rotates and attaches the spacecraft to the bottom of the station’s Unity module. Coverage of installation will begin at 7 a.m.”
“Cygnus will remain at the space station until Dec. 4, when the spacecraft will depart the station and deploy several CubeSats before its fiery reentry into Earth’s atmosphere as it disposes of several tons of trash.”
Under the Commercial Resupply Services (CRS) contract with NASA, Orbital ATK will deliver approximately 28,700 kilograms of cargo to the space station. OA-8 is the eighth of these missions.

5 years after a heart throbbing Martian touchdown, Curiosity is climbing Vera Rubin Ridge in search of “aqueous minerals” and “clays” for clues to possible past life while capturing “truly breathtaking” vistas of humongous Mount Sharp – her primary destination – and the stark eroded rim of the Gale Crater landing zone from ever higher elevations, NASA scientists tell Universe Today in a new mission update.
“Curiosity is doing well, over five years into the mission,” Michael Meyer, NASA Lead Scientist, Mars Exploration Program, NASA Headquarters told Universe Today in an interview.
“A key finding is the discovery of an extended period of habitability on ancient Mars.”
The car-sized rover soft landed on Mars inside Gale Crater on August 6, 2012 using the ingenious and never before tried “sky crane” system.
A rare glimpse of Curiosity’s arm and turret mounted skyward pointing drill is illustrated with our lead mosaic from Sol 1833 of the robot’s life on Mars – showing a panoramic view around the alien terrain from her current location in October 2017 while actively at work analyzing soil samples.
“Your mosaic is absolutely gorgeous!’ Jim Green, NASA Director Planetary Science Division, NASA Headquarters, Washington D.C., told Universe Today
“We are at such a height on Mt Sharp to see the rim of Gale Crater and the top of the mountain. Truly breathtaking.”
The rover has ascended more than 300 meters in elevation over the past 5 years of exploration and discovery from the crater floor to the mountain ridge. She is driving to the top of Vera Rubin Ridge at this moment and always on the lookout for research worthy targets of opportunity.
Additionally, the Sol 1833 Vera Rubin Ridge mosaic, stitched by the imaging team of Ken Kremer and Marco Di Lorenzo, shows portions of the trek ahead to the priceless scientific bounty of aqueous mineral signatures detected by spectrometers years earlier from orbit by NASA’s fleet of Red Planet orbiters.
“Curiosity is on Vera Rubin Ridge (aka Hematite Ridge) – it is the first aqueous mineral signature that we have seen from space, a driver for selecting Gale Crater,” NASA HQ Mars Lead Scientist Meyer elaborated.
“And now we have access to it.”
The Sol 1833 photomosaic illustrates Curiosity maneuvering her 7 foot long (2 meter) robotic arm during a period when she was processing and delivering a sample of the “Ogunquit Beach” for drop off to the inlet of the CheMin instrument earlier in October. The “Ogunquit Beach” sample is dune material that was collected at Bagnold Dune II this past spring.
The sample drop is significant because the drill has not been operational for some time.
“Ogunquit Beach” sediment materials were successfully delivered to the CheMin and SAM instruments over the following sols and multiple analyses are in progress.
To date three CheMin integrations of “Ogunquit Beach” have been completed. Each one brings the mineralogy into sharper focus.
What’s the status of the rover health at 5 years, the wheels and the drill?
“All the instruments are doing great and the wheels are holding up,” Meyer explained.
“When 3 grousers break, 60% life has been used – this has not happened yet and they are being periodically monitored. The one exception is the drill feed (see detailed update below).”
NASA’s 1 ton Curiosity Mars Science Laboratory (MSL) rover is now closer than ever to the mineral signatures that were the key reason why Mount Sharp was chosen as the robots landing site years ago by the scientists leading the unprecedented mission.
Along the way from the ‘Bradbury Landing’ zone to Mount Sharp, six wheeled Curiosity has often been climbing. To date she has gained over 313 meters (1027 feet) in elevation – from minus 4490 meters to minus 4177 meters today, Oct. 19, 2017, said Meyer.
The low point was inside Yellowknife Bay at approx. minus 4521 meters.
VRR alone stands about 20 stories tall and gains Curiosity approx. 65 meters (213 feet) of elevation to the top of the ridge. Overall the VRR traverse is estimated by NASA to take drives totaling more than a third of a mile (570 m).
“Vera Rubin Ridge” or VRR is also called “Hematite Ridge.” It’s a narrow and winding ridge located on the northwestern flank of Mount Sharp. It was informally named earlier this year in honor of pioneering astrophysicist Vera Rubin.
The intrepid robot reached the base of the ridge in early September.
The ridge possesses steep cliffs exposing stratifications of large vertical sedimentary rock layers and fracture filling mineral deposits, including the iron-oxide mineral hematite, with extensive bright veins.
VRR resists erosion better than the less-steep portions of the mountain below and above it, say mission scientists.
What’s ahead for Curiosity in the coming weeks and months exploring VRR before moving onward and upwards to higher elevation?
“Over the next several months, Curiosity will explore Vera Rubin Ridge,” Meyer replied.
“This will be a big opportunity to ground-truth orbital observations. Of interest, so far, the hematite of VRR does not look that different from what we have been seeing all along the Murray formation. So, big question is why?”
“The view from VRR also provides better access to what’s ahead in exploring the next aqueous mineral feature – the clay, or phyllosilicates, which can be indicators of specific environments, putting constraints on variables such as pH and temperature,” Meyer explained.
The clay minerals or phyllosilicates form in more neutral water, and are thus extremely scientifically interesting since pH neutral water is more conducive to the origin and evolution of Martian microbial life forms, if they ever existed.
How far away are the clays ahead and when might Curiosity reach them?
“As the crow flies, the clays are about 0.5 km,” Meyer replied. “However, the actual odometer distance and whether the clays are where we think they are – area vs. a particular location – can add a fair degree of variability.”
The clay rich area is located beyond the ridge.
Over the past few months Curiosity make rapid progress towards the hematite-bearing location of Vera Rubin Ridge after conducting in-depth exploration of the Bagnold Dunes earlier this year.
“Vera Rubin Ridge is a high-standing unit that runs parallel to and along the eastern side of the Bagnold Dunes,” said Mark Salvatore, an MSL Participating Scientist and a faculty member at Northern Arizona University, in a mission update.
“From orbit, Vera Rubin Ridge has been shown to exhibit signatures of hematite, an oxidized iron phase whose presence can help us to better understand the environmental conditions present when this mineral assemblage formed.”
Curiosity is using the science instruments on the mast, deck and robotic arm turret to gather detailed research measurements with the cameras and spectrometers. The pair of miniaturized chemistry lab instruments inside the belly – CheMin and SAM – are used to analyze the chemical and elemental composition of pulverized rock and soil gathered by drilling and scooping selected targets during the traverse.
A key instrument is the drill which has not been operational. I asked Meyer for a drill update.
“The drill feed developed problems retracting (two stabilizer prongs on either side of the drill retract, controlling the rate of drill penetration),” Meyer replied.
“Because the root cause has not been found (think FOD) and the concern about the situation getting worse, the drill feed has been retracted and the engineers are working on drilling without the stabilizing prongs.”
“Note, a consequence is that you can still drill and collect sample but a) there is added concern about getting the drill stuck and b) a new method of delivering sample needs to be developed and tested (the drill feed normally needs to be moved to move the sample into the chimera). One option that looks viable is reversing the drill – it does work and they are working on the scripts and how to control sample size.”
Ascending and diligently exploring the sedimentary lower layers of Mount Sharp, which towers 3.4 miles (5.5 kilometers) into the Martian sky, is the primary destination and goal of the rover’s long term scientific expedition on the Red Planet.
“Lower Mount Sharp was chosen as a destination for the Curiosity mission because the layers of the mountain offer exposures of rocks that record environmental conditions from different times in the early history of the Red Planet. Curiosity has found evidence for ancient wet environments that offered conditions favorable for microbial life, if Mars has ever hosted life,” says NASA.
Stay tuned. In part 2 we’ll discuss the key findings from Curiosity’s first 5 years exploring the Red Planet.
As of today, Sol 1850, Oct. 19, 2017, Curiosity has driven over 10.89 miles (17.53 kilometers) since its August 2012 landing inside Gale Crater from the landing site to the ridge, and taken over 445,000 amazing images.
