President Barack Obama has said he wants to get to Mars by the 2030s, but his is the latest in a series of plans to get there. Every president seems to have a new idea of Mars exploration.
A Congressional committee this week tried to cut through the noise to get some clear messages about what to do. (Context: NASA’s fiscal 2014 budget is up for discussion, so this has budgetary relevance.)

So. We had four witnesses with maybe 150 to 200 years of combined space experience appearing before the subcommittee on space on Tuesday (May 21), each with a plan. To wit, here is a very brief summary of their individual positions:
– Louis Friedman, executive director emeritus of The Planetary Society (who co-led the co-leader of the Keck Institute for Space Studies Asteroid Retrieval Mission Study): Do the asteroid mission proposed by NASA. It will launch four to five years from now. If done properly, it would be a great opportunity for humans to explore as well as for commercial opportunities in mining.
– Paul Spudis, senior staff scientist at the NASA-funded Lunar and Planetary Institute:Return to the moon. It’s close, so close to Earth that we can operate rovers by remote control. It’s a good spot to learn more about the solar system, and it provides practice for us in living off the resources of the land as it has water — a tool for life support and energy.
– Steve Squyres, Cornell University planetary scientist renowned for his Mars rover research: Go to cislunar space, the area close to the moon. It’s an easily accessible spot in a restricted budget environment. Thinking beyond that is not realistic in the current budget environment.
– Douglas Cooke, NASA’s former associate administrator for the exploration systems mission directorate: Re-establish lunar exploration. The asteroid mission would not connect well with the long-term strategy, but the lunar surface would as (like Mars) it is a hostile environment suitable for testing planetary exploration technologies.

Representatives then peppered the space experts with tons of questions, such as:
– How best to bring in international partners?
– Should we be concerned about other countries talking about going to the moon themselves, such as Russia and China?
– Should we take away from other NASA programs, such as astronomy or debris retrieval in orbit, to focus on Mars exploration? (Recall that Mars science was slashed in 2012, including the loss of participation in ExoMars.)
– How do we interest the public in the mission? The asteroid retrieval (which many committee members heavily criticized as one released with little outside consultation) doesn’t seem to spark with the person on the street.
Take a listen of the experts’ answers in full in the archived webcast (available here).
But also — what’s your take? Is it worth going to Mars in the first place, and if so, how do we best achieve that? Please leave your thoughts in the comments.

The International Space Station may soon have its very own Star Trek food replicator.
Earlier this week, NASA awarded a $125,000 six month grant to the Systems & Materials Research Cooperation to design a 3D printer capable of printing a pizza from 30-year shelf stable foodstuffs.
Founded by Anjan Contractor, SMRC built a basic food printer from a chocolate printer to win NASA’s Small Business Innovation Research Program in a trial video. The design is based on an open-source RepRap 3D printer.
Contractor and SMRC will begin construction on the pizza-printing prototype in two weeks. Pizza has been one item missing from astronauts menu for years. The 3D printer would “build-up” a pizza serving by first layering out the dough onto a heated plate then adding tomato sauce and toppings.
But this isn’t your mother’s pizza, as the proteins would be provided by cartridge injectors filled with organic base powders derived from algae, insects and grass.
Yummy stuff, to be sure!
Of course, one can see an immediate application of 3D food printing technology for long duration space missions. Contractor and SMRC envisions 3D food printing as the wave of the future, with the capacity to solve world hunger for a burgeoning human population.
Could a 3D food printer be coming to a kitchen near you?
Curiously, printing confectioneries and pet food pellets would be the simplest application of said technology. Printing a soufflé and crowned rack of lamb will be tougher. 3D printing technology has made great strides as of late, and RepRap has made a printer which is capable of printing itself. Those who fear the rise of Von Neumann’s self-replicating robots should take note…
Should we welcome or fear our self-replicating, pizza-bearing overlords?
The International Space Station is due for the delivery of its first 3D printer in 2014. This will give astros the capability to fabricate simple parts and tools onsite without requiring machining. Of course, the first question on our minds is: How will a 3D printer function in zero-g? Will one have tomato paste an insect parts flying about? Recent flights aboard a Boeing 727 by Made in Space Inc have been testing 3D printers in micro-gravity environments.

Further afield, 3D replicators may arrive on the Moon or Mars ahead of humans, building a prefab colony with raw materials available for colonists to follow.

Will 3D food replicators pioneered by SMRC be a permanent fixture on crewed long duration space missions? Plans such as Dennis Tito’s Mars 2018 flyby and the one way Mars One proposal will definitely have to address the dietary dilemmas of hungry astronauts. Biosphere 2 demonstrated that animal husbandry will be impractical on long term missions. Future Martian colonists will definitely eat much farther down the food chain to survive. SpaceX head Elon Musk has recently said in a Twitter response to PETA that he won’t be the “Kale Eating Overlord of Mars,” and perhaps “micro-ranching” of insects will be the only viable alternative to filet mignon on the Red Planet. Hey, it beats Soylent Green… and the good news is, you can still brew beer from algae!

Would YOU take a one way journey to Mars? Would you eat a bug to do it? It’ll be interesting to watch these 3D printers in action as they take to space and print America’s favorite delivery fast food. But it’s yet to be seen if home replicators will put Dominos Pizza out of business anytime soon. Perhaps they’ll only be viable if they can print a pizza in less than “30 minutes!”

It was surely one of those moments where NASA could hardly wait to tear off the shrink wrap. Sierra Nevada Corp.’s privately constructed Dream Chaser spacecraft engineering test article arrived at the Dryden Flight Research Center last week — wrapped in plastic for shipping protection — ahead of some flight and runway tests in the next few months.
“Tests at Dryden will include tow, captive-carry and free-flight tests of the Dream Chaser. A truck will tow the craft down a runway to validate performance of the nose strut, brakes and tires,” NASA stated.
“The captive-carry flights will further examine the loads it will encounter during flight as it is carried by an Erickson Skycrane helicopter. The free flight later this year will test Dream Chaser’s aerodynamics through landing.”
The ultimate goal is to get the United States bringing its own astronauts into space again.

Sierra Nevada, Space Exploration Technologies (SpaceX) and the Boeing Co. are all receiving NASA funding under its Commercial Crew Integrated Capability (CCiCap) initiative that is intended to restart flights from American soil into low-Earth orbit.
For Sierra Nevada, the company aims to launch its mini shuttle aboard an Atlas V rocket and then, like the shuttle, come back to Earth on a runway. SpaceX and Boeing are taking a different path — making spacecraft capable of launching on the Falcon 9 and Atlas V rockets (respectively) and then coming home under a parachute.
There’s still some questions about when the program will start, though. In media reports, NASA administrator Charles Bolden has said funding threats for NASA’s 2014 request are imperiling the current commercial crew target of 2017.
NASA astronaut Jack Fischer and three others recently took part in approach and landing simulations of the Dream Chaser at Langley Research Center in Hampton. Check out the video below.

Tony Stark has been to a lot of cool places in that Iron Man get-up of his. But low Earth orbit might still be a bit beyond his operational flight envelope. Not so for the developers of the revolutionary RL Mark VI Space Diving suit. A hi-tech ensemble consisting of augmented reality goggles, power gloves, control moment gyros, and a low-cost commercial space suit, the RL Mark VI will allow future thrill seekers and space tourists an experience that up until now could only be imagined in the boldest science fiction.
A joint collaboration between Solar System Express and Juxtopia LLC., two minority-owned hi-tech startups both based in Baltimore, Maryland, the RL MARK VI Space Diving configuration will allow the well-equipped space tourist of the near future the opportunity to actually return to Earth without his spaceship.
Space diving is the next big step beyond sky diving, and it is envisioned as a concept that would allow spaceflight participants a means of escape from a possibly disastrous on-orbit emergency, or perhaps just a new recreational activity for those no longer satisfied with merely jumping out of aircraft. The RL MARK VI would allow high-altitude jumps from near-space, suborbital space, and eventually low Earth orbit itself.
The first few flight tests of the MARK VI hardware will follow a profile very reminiscent to that of the recent record-breaking Red Bull Stratos dive of Felix Baumgartner, where the daring aerialist completed his plunge through the stratosphere with a soft parachute touchdown back on terra firma. But the ultimate goal of this futuristic project is far more radical than that. Eventually, through the use of modern “wing suit” skydiving technology and assisted by miniature aerospike engines attached to specially designed footwear, the space diver will end his spectacular glide through the heavens with a propulsive, power-assisted landing on two feet. No parachute. At all. Just like Tony Stark does it in the movies.
In addition to Hollywood, the RL Mark VI also draws upon history for its inspiration. Major Robert Lawrence, United States Air Force, was America’s first African-American astronaut. Major Lawrence was killed on December 8, 1967 in a test flight at Edwards Air Force Base in California before his dream of flying in space ever came to pass. In his honor the principal design team at Solar System Express chose to use his initials for the product code name of this revolutionary new concept.
On October 2, 2012, the birthday of Robert Lawrence, Blaze Sanders, Chief Technology Officer of Solar System Express, ratified a licensing agreement with Dr. Jayfus Doswell, president and CEO of Juxtopia, for the use of Juxtopia’s Augmented Reality (AR) head mounted display technology.
Similar in functionality to Google Glass, Juxtopia’s AR Goggles are primarily intended to provide the space diver with a continuous stream of vital information that will keep him on course and within safe life-support parameters throughout the duration of his jump. These visually displayed real-time dynamic analytics will tell the jumper his heart rate, respiration, internal space suit temperature, and his external temperature as well. They will provide data on GPS location, elevation, and rates of acceleration and deceleration. An FAA radar display of the local airspace will always indicate his current relative position.

Unlike Google Glass there will be no video mode for these goggles. Instead they will work on the principal of “Optical See-Through,” much like the Heads Up Display on a modern fighter jet, that overlays numerical information and other visual symbology over the pilot’s view of the outside world. In the words of Dr. Doswell, “Video mode works fine for Hollywood, but in real life if you lose video during the jump then you’re flying blind and unlike in the movies there is no quick reboot option.”
The goggles will respond to voice commands specifically addressed to the name that the diver has designated for the RL MARK VI‘s system computer. Special software algorithms will filter the diver’s voice and eliminate all “false positives” such as wind, air, engine sounds and any other noise that is not human speech. The final result of this filtered audio signal is referred to as “pure speech.” Such audio commands will be used to turn the RL MARK VI’s systems on and off, to eject various hardware components from the diver’s body at different altitudes, to control suit cams and various lighting options, and to control voice communications to a ground control station.
In addition to voice commands, according to Dr. Doswell, “other human-computer interface modalities are being investigated for control of the MARK VI during its high speed decent as well.” Interfaces such as the electrical activity in your muscles harnessed by gesture control systems from MYO, and a distance only radio frequency sensor developed by Dr. Kuhlman at the University of Maryland, College Park, MD.
Modern fighter aircraft also employ specific audio outputs in cases of emergency or imminent danger. The MARK VI will be no different. Juxtopia is developing a culturally-specific system of programmable user preferences that will allow the diver to select his own audio alarms for any possible in-flight emergency and any other critical decision points such as altitude level or diminishing fuel state. This approach will help to enhance the international marketability of the MARK VI as well as ensure safety throughout the space dive for potential users from a variety of different cultures.
This video provides a taste of what space diving will be like:
Falling through the vacuum of space will be quite different than a dive that begins in the relative thickness of Earth’s lower atmosphere. There will be no aerodynamic forces acting upon the diver’s body that will allow him to stabilize his jump. This problem will be solved by a pair of gyroscopic boots and the fingertip controls built into the gloves of the diver’s spacesuit. Commands so issued to the control momentum gyroscopes built into his footwear will establish proper attitude and help to steady his fall through the airless void.
As a safety precaution a flat spin compensator will automatically actuate after more than five seconds if the diver is unable to maintain adequate manual control. As the diver descends through the upper atmosphere, eventually the air will thicken to the point where aerodynamic forces will allow him to control the attitude of his body. Olav Zipser, word-renowned skydiver and lead jumper on the FreeFly Astronaut Project, has praised the new suit. “Your product would be a great way to stabilize my decent during the first 30 seconds of free fall, when there is virtually zero atmosphere,” he said.

The final function of the diver’s gyroscopic boots will kick in as he nears the surface of the Earth, and he fires off his miniature aerospike thrusters to smoothly lower himself to the ground for a two-point upright landing.
Two different landing scenarios are presently under consideration: “a feet-down” landing where the aerospikes fire into action from an altitude of hundred feet, gently lowering the diver down to earth; and the much more daring and challenging “wing suit flare up” where the diver swoops within ten feet of pay dirt before pulling up sharply and then lighting off his thrusters to initiate his controlled descent to the ground.
Solar System Express intends to first test this propulsive landing capability somewhere around 2016, with a production model of the RL MARK VI coming to market about a year later. Until then any live tests of the system will conclude with traditional parachute jumps. Data collected during these jumps, along with rigorous control system testing and computer simulated recreations of each space dive, will enable Blaze Sanders and his team to refine the parameters and the protocols required for a text book propulsive landing.

Mounted on the front of the jumper’s space suit will be a “high intensity LED chest piece” powered by energy-storing super capacitors and equipped with miniature stereo cameras which will collect much of the data necessary for recreating the jump in a 3D computer simulation. When finally transferred to video all of this collected 3D data should easily yield the kind of YouTube upload that one can point to with pride for years to come.
The Gravity Development Board, a proprietary piece of hardware designed by Solar System Express, will serve as the main interface between the MARK VI’s three major components as well as the device which controls all critical systems.
According to Mr. Sanders, “The GDB will be the first space-rated open hardware electronic prototyping board, enabling any type of person to create space qualified hardware. The GDB will replace the Arduino Uno® as the preferred high-level prototyping environment, by being up to forty times faster, seventy percent smaller, having integrated high power drivers (capable of handling one hundred times the current), with more flexible Input/Output configurations, and yet be still much easier to program via 12 Blocks™, the powerful, intuitive visual language used for robotic programming. Engineers, artists, and designers are thus enabled to create any project they can imagine. Our quick release breakout board, the ‘Ejection Seat™,’ allows for easy prototyping, yet keeps the GDB form factor small and robust enough to use in New Space start-up product releases.”
Final Frontier Design, of Brooklyn, New York, is working with Solar System Express on a customized version of their low-cost Intra-Vehicular Activity IVA 3G spacesuit, first introduced to the public last year and successfully crowd funded through an online kickstarter campaign. The entire RL MARK VI ensemble, along with the 3G spacesuit and a protective thermal outer covering, will be put through a rigorous testing regime beginning in June of 2014. Ground based testing will commence with a series of thermal and vacuum chamber tests, and vertical wind tunnel tests to be conducted at the Goddard Spaceflight Center in Greenbelt, Maryland.
The protective thermal covering will be fashioned from lightweight layers of aerogel and NASA Space Shuttle-like flexible insulation blankets formed into a garment that will serve as the spacesuit’s outermost layer. This is the material that will protect the space diver from the heat of reentry as he plunges through the earth’s upper atmosphere. Solar System Express has already started conversations with several wing suit manufacturers interested in employing this revolutionary thermal technology into their product line.
The first tests at altitude should begin around July of 2016. They will commence with two-kilometer parachute jumps from a helium balloon-tethered tower that will comprise the major test platform of The LiftPort Group’s Lunar Space Elevator Project. Eventually near-space jumps from as high as 40 kilometers will be conducted by Olav Zipser and his FreeFly Astronaut Project using a specially modified rocket designed and manufactured by InterOrbital Systems of Mojave, California.
No firm dates have been set for suborbital and orbital testing but initial plans call for the use of a human medical robot prototype supplied by Juxtopia to be used as the test subject for these first jumps before real live space divers eventually become involved.
Blaze Sanders estimates the total development costs to bring the RL MARK VI to market at around $2.2 million. He has already invested about $100,000 of his own time and money into the project. In the next three years he expects to generate another $1.1 million dollars in revenue through sales of his company’s Gravity Development Board. He expects to generate additional revenue from a wide variety of sources including ongoing consulting fees, government grants and loans, angel investment, kickstarter campaigns, and technical consulting fees from motion picture productions already interested in the use of his technology, as well as a video game simulation also based on his revolutionary hardware.
Should he ultimately succeed then, who knows, one day he may end up just as rich and successful as Tony Stark himself. He’s already got the suit. And he’s prepared to take it to dazzling new heights.
NASA astronaut Sally Ride, who died in 2012. Credit: NASA
Sally Ride was only 32 years old when she flew into space for the first time 30 years ago, in June 1983. She died last year at 61, at an age that many considered very young. In that generation of time, however, the exploits of America’s first woman in space in flight and education touched countless Americans.
This week, the accolades are piling up for the two-time space flyer. Besides her astronaut exploits, she was a Rogers Commission investigator of the 1986 Challenger explosion and the founder of Sally Ride Science, which encourages children to pursue careers in science, technology, education and math (STEM).
In the past few days alone, Ride generated a bunch of posthumous tributes:
– She will receive the Presidential Medal of Freedom sometime later this year;
– The EarthKAM science instrument (which includes participation from students) on the International Space Station will bear her name.
And that’s not all. There were also star-studded public ceremonies devoted to her memory.

Music, art and science all met at a gala at Washington, D.C.’s John F. Kennedy Center for the Performing Arts on Monday (May 20). The performances focused on things that had meaning to Ride, NASA stated, including a performance of Claude Debussy’s “Clair de Lune” and a reading of Mary Oliver’s poem “The Summer Day.”
Speakers at the event included astronaut Leland Melvin (now NASA’s associate administrator for education), astronaut Pam Melroy (a former space shuttle commander), and Senator Barbara Mikulski of Maryland.
“I’m thrilled to pay tribute to Sally because her dedication and superb talent cemented the value of women’s contributions in space and in science, smoothing the path for all women to achieve success,” stated Melroy.
“Sally showed the world what was possible, opening the eyes of millions of women and men to what could be. Her achievements in space inspired a generation of young women, and her achievements in STEM education will pass that legacy of inspiration on to future generations.”
The Smithsonian also held a lecture in honor of Ride’s memory on May 17.
The 1.5-hour lecture (which is just above this text and definitely worth your time to see) includes commentary from a cross-section of space experts on Ride’s legacy. Speakers represented everything from the Smithsonian National Air and Space Museum to NASA’s Johnson Space Center to USA Today.
“We all admire Dr. Ride, but I don’t know that everyone in the room appreciates fully and remembers fully the history of what she accomplished,” said Margaret Weitekamp, a curator in the Smithsonian’s space history division who focuses on women in aviation, in opening remarks to the event.
Weitekamp pointed to investigations in the 1950s concerning women in space, showing that they could have advantages over men: they’re smaller (easier to fit in a spacecraft) and at the time were linked to studies showing women have fewer pulmonary problems, a higher tolerance to pain, and better performance in isolation tests.
She also cited early forays for women in space, including Lovelace’s Women in Space program, which she characterized as the first thorough physiological investigation of how women fare in that field. You can read more about their exploits on this NASA page.

NASA’s Curiosity rover has just successfully bored inside ancient rocks on Mars for only the 2nd time since her nail biting landing in August 2012 inside Gale Crater as she searches for the ingredients of life.
On Sunday, May 20, the rover drilled about 2.6 inches (6.6 centimeters) deep into a target named “Cumberland” to collect powdery samples from the rock’s interior that hold the secrets to the history of water and habitability on the Red Planet.
“Cumberland” is literally just a stone’s throw away from the first drill target named “John Klein” where Curiosity bored the historic first drill hole on an alien world three months ago in February.
NASA’s Mars rover Curiosity drilled into this rock target, “Cumberland,” during the 279th Martian day, or sol, of the rover’s work on Mars (May 19, 2013) and collected a powdered sample of material from the rock’s interior. Analysis of the Cumberland sample using laboratory instruments inside Curiosity will check results from “John Klein,” the first rock on Mars from which a sample was ever collected and analyzed. The two rocks have similar appearance and lie about nine feet (2.75 meters) apart. Image Credit: NASA/JPL-Caltech/MSSS
Analysis of the gray colored, powdery “John Klein” sample by Curiosity’s pair of onboard chemistry labs – SAM & Chemin – revealed that this location on Mars was habitable in the past and possesses the key chemical ingredients required to support microbial life forms – thereby successfully accomplishing the key science objective of the mission and making a historic discovery.
The Cumberland powder will be fed into SAM and Chemin shortly through a trio of inlet ports on the rover deck.
‘Cumberland’ lies about nine feet (2.75 meters) west of ‘John Klein’. Both targets are inside the shallow depression named ‘Yellowknife Bay’ where Curiosity has been exploring since late 2012.
The six wheeled NASA robot arrived at Cumberland just last week on May 14 (Sol 274) after a pair of short drives.

The science team directed Curiosity to drill into ‘Cumberland’ to determine if it possesses the same ingredients found at “John Klein” and whether the habitable environment here is widespread and how long it existed in Mars’ history.
“We’ll drill another hole [at Cumberland] to confirm what we found in the John Klein hole,” said John Grotzinger to Universe Today. Grotzinger, of the California Institute of Technology in Pasadena, Calif., leads NASA’s Curiosity Mars Science Laboratory mission.
“The favorable conditions included the key elemental ingredients for life, an energy gradient that could be exploited by microbes, and water that was not harshly acidic or briny,” NASA said in a statement.

This week the rover scooted about 9 feet to the right to Cumberland (right of center) for 2nd drill campaign on May 19, 2013 (Sol 279). Credit: NASA/JPL-Caltech/Ken Kremer/Marco Di Lorenzo
‘Cumberland’ and ‘John Klein’ are patches of flat-lying bedrock shot through with pale colored hydrated mineral veins composed of calcium sulfate and featuring a bumpy surface texture inside the ‘Yellowknife Bay’ basin that resembles a dried out lake bed.
“We have found a habitable environment [at John Klein] which is so benign and supportive of life that probably if this water was around, and you had been on the planet, you would have been able to drink it,” said Grotzinger.
Curiosity will remain at Cumberland for several weeks to fully characterize the area and then continue exploring several additional outcrops in and around Yellowknife Bay.
“After that we’re likely to begin the trek to Mt. Sharp, though we’ll stop quickly to look at a few outcrops that we passed by on the way into Yellowknife Bay,” Grotzinger told me.
One stop is likely to include the ‘Shaler’ outcrop of cross-bedding that was briefly inspected on the way in.
Thereafter the 1 ton rover will resume her epic trek to the lower reaches of mysterious Mount Sharp, the 3.5 mile (5.5 km) high layered mountain that dominates her landing site and is the ultimate driving goal inside Gale Crater.

A menagarie of animals launched to space last month has arrived back on Earth — with a few casualties for the voyage.
Bion-M, a small satellite carrying gerbils, lizards, mice and other critters, launched in April from the Plesetsk Cosmodrome in Russia and arrived, as planned, safely on Earth on Sunday (May 19).
However, not all of the assorted crew survived the voyage.
“This is the first time that animals have been put in space on their own for so long,” said Vladimir Sychov of the Russian Academy of Sciences, as reported by several news agencies. Half of the 45 mice were lost in the journey, which was expected, but the eight gerbils unexpectedly died “because of equipment failure”, he added.

Still, the scientists expect to pull a lot of long-duration data out of the mission. It is expected to help scientists better understand the effects of microgravity on biological organisms, with applications for long human voyages such as a trip to Mars.
Microgravity does a number on human systems, as just-returned-from-space astronaut Chris Hadfield eloquently described recently.
Bones lose calcium, muscles shrink and there are changes to your blood pressure flow and even your eyes. Taking a trip to space is like experiencing aging on fast-forward (although luckily, the effects are mostly reversible.)

“Knowledge gained in the use of animals reveals the fundamental mechanisms of adaptation to spaceflight,” NASA stated in a web page about the mission. “Such knowledge provides insight for potential long-duration human spaceflight risk mitigation strategies and potential new approaches for Earth bound biomedical problems.”
Before Bion-M journeyed to space, most mouse studies only took place during space shuttle missions that were in orbit for a maximum of two weeks. The new 30-day mission doubled the length of previous studies and also allow more advanced technologies to be brought to bear on the science, stated NASA, who participated in the mission.
“NASA researchers will study the cellular mechanisms responsible for spaceflight-induced changes on tissues and cell growth in mice, including muscle, bone and the cardiovascular and reproductive systems,” the agency wrote in an April press release. “They also will study behavioral effects in gerbils.”
British astronaut Timothy Peake training in a Soyuz simulator. (European Space Agency)
The name is Peake. Timothy Peake. And he’s set to follow in the (fictional) footsteps of fellow British citizen James Bond with a stay on a space station.
In 2015, Peake will be the first British citizen to live for six months on the International Space Station. He’ll be a part of the Expedition 46/47 crew. NASA hasn’t publicly named all of his seatmates yet, but expect a lot of excitement across the former Empire when Peake has his turn.
“This is another important mission for Europe and in particular a wonderful opportunity for European science, industry and education to benefit from microgravity research,” Peake said in a statement.
There have been a bevy of British astronauts before Peake, both as joint nationals within NASA and even for private spaceflights (remember Mark Shuttleworth‘s and Richard Garriott’s ‘vacations’ on station?) Also, it’s quite possible that even more British citizens will get into space before Peake does in 2015.

That’s not due to lack of qualifications on Peake’s part, though. He participated in the NEEMO 16 underwater mission and took part in a periodic underground cave expedition that ESA runs to simulate spaceflight, among other duties. Peake also used to be a helicopter pilot in the British Army; the media is already calling him “Major Tim” for that reason in homage to David Bowie’s “Space Oddity” song (most recently pwned by Canadian astronaut Chris Hadfield.)
But 2015 also marks when the ground is expected to shift, so to speak, in commercial spaceflight. It’s expected that Britain’s Virgin Galactic will start regular suborbital runs around that year. (XCOR’s Lynx suborbital spacecraft also may start flights around the same time, perhaps with British citizens on board.)
British songstress Sarah Brightman previously announced she will make a much shorter visit to the space station in 2015. That hasn’t been fully confirmed yet — there aren’t many seats available on Soyuz spacecraft after the end of the shuttle program — but it’s possible she could make it up there.
Getting back to Peake, some important secondary news came out for the latest corps of European astronauts: all of them are expected to fly before the end of 2017, as ESA previously promised.

The astronauts, who call themselves ‘The Shenanigans’, are already having an exciting month as Italian Luca Parmitano is scheduled to fly to the International Space Station May 28. (In a spaceflight first, he’s doing outreach with a 15-year-old while in orbit.)
Two other Shenanigans are assigned to spaceflights: Alexander Gerst and Samantha Cristoforetti, who will make the journey around 2014.
It’ll be a little while before the last two astronauts, Andreas Mogensen and Thomas Pesquet, get confirmation of flight assignments, but it should be by announced by mid-2015, stated ESA’s director-general, Jean-Jacques Dordain.
ESA has made numerous contributions to the station, racking up credits that the federation of countries can use towards astronaut spaceflights. Among them are the Columbus laboratory, the Automated Transfer Vehicle cargo ship and the cupola (a panoramic window with a history of awesome astronaut shots.)

“The value of Europe’s astronauts and the training given at the European astronaut center is reflected in the large number of mission assignments awarded to ESA astronauts,” stated Thomas Reiter, ESA’s director of human spaceflight and operations.
You can follow Peake’s training at his Twitter account, and he has promised to keep up his social media efforts in space.
“I certainly will be tweeting from space. A large part of what I want to achieve on this mission is to try to inspire a generation and encourage them to continue to support space flight and microgravity research,” Peake said in a press conference, as reported by The Guardian.

It’s time at last for “Drill, Baby, Drill!” – Martian Style.
Well, check out this enlightening and cool new NASA video for an exquisitely detailed demonstration of just how Curiosity shakes, rattles and rolls on the Red Planet and swallows that mysterious Martian powder.
“Shake, shake, shake… shake that sample. See how I move drilled rock to analytical instruments,” tweeted Curiosity to millions of fans.
Get set to witness Martian gyrations like you’ve never seen before.
After a pair of short but swift moves this past week, NASA’s Curiosity rover is finally in position to bore into the Red Planet’s alien surface for the second time – at a target called “Cumberland.”
See where “Cumberland” is located in our panoramic photo mosaic below.
“Two short drives & 3.8 meters later, I’m zeroing in on my second Mars drilling target,” tweeted Curiosity.

These were Curiosity’s first drives since arriving at the “John Klein” outcrop in mid- January 2013 where she carried out the historic first ever interplanetary drilling by a robot on another world.
For the past few days the robot has snapped a series of close up images of “Cumberland” with the high resolution MAHLI camera on the “hand” of the dextrous robotic arm.
And now that Curiosity has switched to the B-side computer, the rover has switched over to an back up set of never before used cameras on the mast head, which appear to be functioning perfectly.
“Curiosity is now using the new pair of navigation cameras associated with the B-side computer,” said Curiosity science team member Kimberly Lichtenberg to Universe Today.
The rover also evaluated the potential drill site with the ChemCAM and APXS instruments to confirm whether ‘Cumberland’ is indeed a worthy target for the time consuming process to collect the drill tailings for delivery to the duo of miniaturized chemistry labs named SAM and Chemin inside her belly
As outlined in the video, the robot engages in an incredibly complex procedure to collect the drill bit tailings and then move and pulverize them through the chambers of the CHIMRA sample system on the tool turret for processing, filtering and delivery for in situ analysis that could take weeks to complete.

The state-of-the-art SAM and Chemin chemistry labs test aspirin sized quantities of the carefully sieved powder for the presence of organic molecules – the building blocks of life – and determine the inorganic chemical composition.
The science team wants to know how ‘Cumberland’ stacks up compared to ‘John Klein’, inside the shallow depression named ‘Yellowknife Bay’ where Curiosity has been exploring since late 2012.
“We’ll drill another hole to confirm what we found in the John Klein hole,” said John Grotzinger to Universe Today. Grotzinger, of the California Institute of Technology in Pasadena, Calif., leads NASA’s Curiosity Mars Science Laboratory mission.
‘Cumberland’ and ‘John Klein’ are patches of flat-lying bedrock shot through with pale colored hydrated mineral veins composed of calcium sulfate hydrated and a bumpy surface texture at her current location inside the ‘Yellowknife Bay’ basin that resembles a dried out lake bed.
“The bumpiness is due to erosion-resistant nodules within the rock, which have been identified as concretions resulting from the action of mineral-laden water,” according to NASA.
At Yellowknife Bay, Curiosity found evidence for an ancient habitable environment that could possibly have supported simple Martian microbial life forms eons ago when the Red Planet was warmer and wetter.
Analysis of the gray colored rocky Martian powder at ‘John Klein’ revealed that the fine-grained, sedimentary mudstone rock possesses significant amounts of phyllosilicate clay minerals; indicating the flow of nearly neutral liquid water and a habitat friendly to the possible origin of microbes.
Curiosity is expected to drill and swallow the ‘Cumberland’ powder at any moment if all goes well, a team member told Universe Today.

Meanwhile as Curiosity was moving to Cumberland, her older sister Opportunity was blazing a trail at Endeavour Crater on the opposite side of Mars and breaking the distance driving record for an American space rover. Read all about it in my new story – here.

Opportunity pops a ‘wheelie’ on May 15, 2013 (Sol 3308) and then made history by driving further to the mountain ahead on the next day, May 16 (Sol 3309), to establish a new American driving record for a vehicle on another world.

Now more than 9 years and counting into her planned mere 90 day mission to Mars, NASA’s legendary Opportunity rover has smashed past another space milestone and established a new distance driving record for an American vehicle on another world this week.
On Thursday, May 16, the long-lived Opportunity drove another 263 feet (80 meters) on Mars – bringing her total odometry since landing on 24 January 2004 to 22.220 miles (35.760 kilometers) – and broke through the 40 year old driving record set back in December 1972 by Apollo 17 astronauts Eugene Cernan and Harrison Schmitt.
See below our complete map of the 9 Year Journey of Opportunity on Mars.
Cernan and Schmitt visited Earth’s moon on America’s final lunar landing mission and drove their mission’s Lunar Roving Vehicle (LRV-3) 22.210 miles (35.744 kilometers) over the course of three days on the moon’s surface at Taurus-Littrow.

Cernan was ecstatic at the prospect of the Apollo 17 record finally being surpassed.
“The record we established with a roving vehicle was made to be broken, and I’m excited and proud to be able to pass the torch to Opportunity, ” said Cernan to team member Jim Rice of NASA Goddard Space Flight Center, Greenbelt, Md, in a NASA statement.
And Opportunity still has plenty of juice left!
So, although there are no guarantees, one can reasonably expect the phenomenal Opportunity robot to easily eclipse the ‘Solar System World Record’ for driving distance on another world that is currently held by the Soviet Union’s remote-controlled Lunokhod 2 rover. See detailed graphic below.
In 1973, Lunokhod 2 traveled 23 miles (37 kilometers) on the surface of Earth’s nearest neighbor.
Why could Opportunity continue farther into record setting territory ?
Because Opportunity’s handlers back on Earth have dispatched the Martian robot on an epic trek to continue blazing a path forward around the eroded rim of the huge crater named ‘Endeavour’ – where she has been conducting ground breaking science since arriving at the “Cape York” rim segment in mid 2011.
Out-of-this-World Records. This chart illustrates comparisons among the distances driven by various wheeled vehicles on the surface of Earth’s moon and Mars. Of the vehicles shown, the NASA Mars rovers Opportunity and Curiosity are still active and the totals for those two are distances driven as of May 15, 2013. Opportunity set the new NASA driving record on May 15, 2013 by traveling 22.220 miles (35.760 kilometers). The international record for driving distance on another world is still held by the Soviet Union’s remote-controlled Lunokhod 2 rover, which traveled 23 miles (37 kilometers) on the surface of Earth’s moon in 1973.

Opportunity has just now set sail for her next crater rim destination named “Solander Point”, an area about 1.4 miles (2.2 kilometers) away – due south from “Cape York.”
Endeavour Crater is 14 miles (22 km) wide, featuring terrain with older rocks than previously inspected and unlike anything studied before. It’s a place no one ever dared dream of reaching prior to Opportunity’s launch in the summer of 2003 and landing on the Meridiani Planum region in 2004.
Opportunity will blast through the world record milestone held by the Lunokhod 2 rover somewhere along the path to “Solander Point.”
Thereafter Opportunity will rack up ever more miles as the rover continues driving further south to a spot called “Cape Tribulation”, that is believed to hold caches of clay minerals that formed eons ego when liquid water flowed across this region of the Red Planet.
It’s a miracle that Opportunity has lasted so far beyond her design lifetime – 37 times longer than the 3 month “warranty.”
“Regarding achieving nine years, I never thought we’d achieve nine months!” Principal Investigator Prof. Steve Squyres of Cornell University told me recently on the occasion of the rovers 9th anniversary on Mars in January 2013.
“Our next destination will be Solander Point,” said Squyres.
Opportunity was joined on Mars by her younger sister Curiosity, currently exploring the crater floor inside Gale Crater since landing on Aug. 6, 2012.
Curiosity is likewise embarked on a epic trek – towards 3 mile high (5.5 km) Mount Sharp some 6 miles away.
Both rovers Opportunity & Curiosity have discovered phyllosilicates, hydrated calcium sulfate mineral veins and vast evidence for flowing liquid water on Mars. All this data enhances the prospects that Mars could have once supported microbial life forms.
The Quest for Life beyond Earth continues ably with NASA’s Martian sister rovers.

Traverse Map for NASA’s Opportunity rover from 2004 to 2013 to Record Setting Drive on May 15. This map shows the entire path the rover has driven during more than 9 years and over 3309 Sols, or Martian days, since landing inside Eagle Crater on Jan 24, 2004 to current location heading south from Cape York ridge at the western rim of Endeavour Crater. On May 15, 2013 Opportunity drove 263 feet (80 meters) southward – achieving a total traverse distance on Mars of 22.22 miles (35.76 kilometers) – and broke the driving record by any NASA vehicle that was previously held by the astronaut-driven Apollo 17 Lunar Rover in 1972.
