Gene Cernan on the Moon during the final EVA of the Apollo 17 mission, Dec. 13, 1972 (NASA/JSC scan)
On December 14, 1972, at about 5:40 a.m. GMT, Apollo 17 astronaut Eugene Andrew “Gene” Cernan returned to the lunar module Challenger after the end of the third mission EVA to join Harrison “Jack” Schmitt, completing nearly two and a half days of surface operations within the Taurus-Littrow site and officially becoming the last human to set foot upon the lunar surface. No one has returned since, and to this day the 80-year-old Cernan still holds the title of “last man on the Moon.”
If that’s not the perfect setup for a documentary film, I don’t know what is. Luckily for us there’s one in the works.
“The Last Man on the Moon,” from UK-based Mark Stewart Productions, tells the story of Gene Cernan and his accomplishments against the backdrop of the Apollo era, when superpowers competed for dominance in space and hotshot flyboys became international heroes. With firsthand accounts from Cernan himself and his family, along with several other astronauts and NASA celebrities, it’s an emotional and intimate account of America’s last lunar voyage.
Watch the trailer below:
According to IMDB the 99-minute documentary directed by Mark Craig is slated for release in the UK (and hopefully U.S.!) sometime this year, although an exact date isn’t listed. There have been advance screenings very recently, at some of which Cernan was present for Q&A sessions. Some viewers are calling it “the best space documentary they have seen” so needless to say I’m pretty excited about it!

It’s time to get ready for Mars, again! NASA has given the approval to begin construction on its 2016 mission, the Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport (InSight) mission.
As the mission implies, the lander (which isn’t moveable) will focus on learning more about the inside of Mars. The idea is to figure out how terrestrial planets are “differentiated” inside between core, mantle and crust. Also, watchers of the Mars program may recognize some parts of the lander, as it will borrow the design from the successful Phoenix mission in 2008.
“We will incorporate many features from our Phoenix spacecraft into InSight, but the differences between the missions require some differences in the InSight spacecraft,” stated Stu Spath, InSight program manager at Lockheed Martin.
“For example, the InSight mission duration is 630 days longer than Phoenix, which means the lander will have to endure a wider range of environmental conditions on the surface.”

NASA mission planners are still determining where InSight will go, but they expect it will be a site near the equator of Mars and that it will last at least two years on the surface.
The Mars lander will include a robotic arm with “surface and burrowing” instruments whose projects are led by the French and German space agencies, which are CNES (National Center of Space Studies) and DLR (German Center for Aerospace), respectively. CNES will contribute a seismic experiment to look at “Marsquakes” and when meteors smack the surface, while DLR’s science experiment will look at interior planetary heat.

The seismometer will sit on the surface, covered up to protect it from the cold and wind, while the heat-flow probe will be hammered in about three to five yards or meters. Investigators also plan an experiment that will communicate with NASA’s Deep Space Network antenna network to see how much the rotation of Mars wobbles, which could hint if the core of the Red Planet is solid or liquid. The mission will also include wind, temperature and pressure sensors, as well as a magnetometer.
“Mars actually offers an advantage over Earth itself for understanding how habitable planetary surfaces can form,” stated Bruce Banerdt, InSight principal investigator at NASA’s Jet Propulsion Laboratory. “Both planets underwent the same early processes. But Mars, being smaller, cooled faster and became less active while Earth kept churning. So Mars better preserves the evidence about the early stages of rocky planets’ development.”
Construction will be led by Lockheed Martin. You can check out more information about InSight at this website. NASA has several missions working at Mars right now, such as the Mars Curiosity rover, the Opportunity rover and the orbiting Mars Reconnaissance Orbiter and Mars Odyssey spacecraft.

It’s amazing to see what some flashes of light can tell us. New images the Hubble Space Telescope took of Saturn not only reveal auroras dancing in the north pole, but also reveal some interesting things about the giant planet’s magnetic field.
“It appears that when particles from the Sun hit Saturn, the magnetotail collapses and later reconfigures itself, an event that is reflected in the dynamics of its auroras,” the European Space Agency wrote in a description of the image.
“Saturn was caught during a very dynamic light show – some of the bursts of light seen shooting around Saturn’s polar regions traveled more than three times faster than the speed of the gas giant’s roughly 10-hour rotation period.”
And for those readers that remember the music video from Saturn that the Cassini spacecraft took — also of auroras — ESA said this new research complements what the other spacecraft did, too.
The research has been accepted for publication in Geophysical Research Letters.

The 30 day flight of the SpaceX-3 Dragon commercial cargo freighter loaded with a huge cache of precious NASA science experiments including a freezer packed with research samples ended today with a spectacular departure from the orbiting lab complex soaring some 266 miles (428 km) above Earth.
Update 3:05 PM EDT May 18: SpaceX confirms successful splashdown at 3:05 p.m. EDT today.
“Splashdown is confirmed!! Welcome home, Dragon!”
Robotics officers at Mission Control at NASA’s Johnson Space Center detached Dragon from the Earth-facing port of the Harmony module at 8 a.m. EDT (1300 GMT) this morning, Sunday, May 18, 2014 using the stations Canadian-built robotic arm.
Engineers had earlier unbolted all 16 hooks and latches firmly connecting the vehicle to the station in preparation.
NASA astronaut Steve Swanson then commanded the gum dropped shaped Dragon capsule’s release from Canadarm2 as planned at 9:26 a.m. EDT (1326 GMT) while the pair were flying majestically over southern Australia.
The undocking operation was shown live on NASA TV.

Swanson was assisted by Russian cosmonaut Alexander Skvortsov as the US- Russian team were working together inside the domed Cupola module.
Following the cargo ships release by the 57 foot long arms grappling snares, Swanson carefully maneuvered the arm back and away from Dragon as it moved ever so slowly in free drift mode.
It was already four feet distant within three minutes of release.
Three departure burns by the Dragon’s Draco maneuvering thrusters followed quickly in succession and occurred precisely on time at 9:29, 9:30 and 9:38 a.m. EST.
Dragon exited the 200 meter wide keep out zone – an imaginary bubble around the station with highly restricted access – at the conclusion of the 3rd departure burn.
“The Dragon mission went very well. It was very nice to have a vehicle take science equipment to the station, and maybe some day even humans,” Swanson radioed after the safe and successful departure was completed.
“Thanks to everyone who worked on the Dragon mission.”
The private SpaceX Dragon spent a total of 28 days attached to the ISS.
The six person international crew from Russia, the US and Japan on Expeditions 39 and 40 unloaded some 2.5 tons of supplies aboard and then repacked it for the voyage home.
The SpaceX resupply capsule is carrying back about 3500 pounds of spacewalk equipment, vehicle hardware, science samples from human research, biology and biotechnology studies, physical science investigations and education activities, as well as no longer needed trash.
“The space station is our springboard to deep space and the science samples returned to Earth are critical to improving our knowledge of how space affects humans who live and work there for long durations,” said William Gerstenmaier, associate administrator for human exploration and operations.
“Now that Dragon has returned, scientists can complete their analyses, so we can see how results may impact future human space exploration or provide direct benefits to people on Earth.”
Among the research investigations conducted that returned samples in the cargo hold were an examination of the decreased effectives of antibiotics in space, better growth of plants in space, T-Cell activation in aging and causes of human immune system depression in the microgravity environment.
The 10 minute long deorbit burn took place as scheduled at 2:10 p.m. EDT (1810 GMT) today.
Dragon returned to Earth for a triple parachute assisted splash down today at around 3:02 p.m. EDT (19:02 GMT) in the Pacific Ocean – some 300 miles west of Baja California.

It will be retrieved by recovery boats commissioned by SpaceX. The science cargo will be extracted and then delivered to NASA’s Johnson Space Center within 48 hours.
Dragon thundered to orbit atop SpaceX’s powerful new Falcon 9 v1.1 rocket on April 18, from Cape Canaveral, Fla.
This unmanned Dragon delivered about 4600 pounds of cargo to the ISS including over 150 science experiments, a pair of hi tech legs for Robonaut 2, a high definition Earth observing imaging camera suite (HDEV), the laser optical communications experiment (OPALS), the VEGGIE lettuce growing experiment as well as essential gear, spare parts, crew provisions, food, clothing and supplies to the six person crews living and working aboard in low Earth orbit.

It reached the ISS on April 20 for berthing.
Dragon is the only unmanned resupply vessel supply that also returns cargo back to Earth.
The SpaceX-3 mission marks the company’s third resupply mission to the ISS under the $1.6 Billion Commercial Resupply Services (CRS) contract with NASA to deliver 20,000 kg (44,000 pounds) of cargo to the ISS during a dozen Dragon cargo spacecraft flights through 2016.
The SpaceX Dragon is among a trio of American vehicles, including the BoeingCST-100 and Sierra Nevada Dream Chaser vying to restore America’s capability to fly humans to Earth orbit and the space station by late 2017, using seed money from NASA’s Commercial Crew Program (CCP) in a public/private partnership. The next round of contracts will be awarded by NASA about late summer 2014.
Another significant milestone was the apparently successful attempt by SpaceX to accomplish a controlled soft landing of the Falcon 9 boosters first stage in the Atlantic Ocean for eventual recovery and reuse. It was a first step in a guided 1st stage soft landing back at the Cape.
The next unmanned US cargo mission to the ISS is set for early morning on June 10 with the launch of the Orbital Sciences Cygnus freighter atop an Antares booster from a launch pad at NASA’s Wallops Flight Facility on the eastern shore of Virginia.

KENNEDY SPACE CENTER, FL – Boeing expects to begin “assembly operations of our commercial CST-100 manned capsule soon at the Kennedy Space Center,” Chris Ferguson, commander of NASA’s final shuttle flight and now director of Boeing’s Crew and Mission Operations told Universe Today in an exclusive one-on-one interview about Boeing’s space efforts. In part 1, Ferguson described the maiden orbital test flights to the ISS set for 2017 – here.
In part 2, we focus our discussion on Boeings’ strategy for building and launching the CST-100 ‘space taxi’ as a truly commercial space endeavor.
To begin I asked; Where will Boeing build the CST-100?
“The CST-100 will be manufactured at the Kennedy Space Center (KSC) in Florida inside a former shuttle hanger known as Orbiter Processing Facility 3, or OPF-3, which is now [transformed into] a Boeing processing facility,” Ferguson told me. “Over 300 people will be employed.” Chris Ferguson, last Space Shuttle Atlantis commander, tests the Boeing CST-100 capsule which may fly US astronauts to the International Space Station in 2017.

During the shuttle era, all three of NASA’s Orbiter Processing Facilities (OPFs) were a constant beehive of activity for thousands of shuttle workers busily refurbishing the majestic orbiters for their next missions to space. But following Ferguson’s final flight on the STS-135 mission to the ISS in 2011, NASA sought new uses for the now dormant facilities.
So Boeing signed a lease for OPF-3 with Space Florida, a state agency that spent some $20 million modernizing the approximately 64,000 square foot hanger for manufacturing by ripping out all the no longer needed shuttle era scaffolding, hardware and equipment previously used to process the orbiters between orbital missions.
Boeing takes over the OPF-3 lease in late June 2014 following an official handover ceremony from Space Florida. Assembly begins soon thereafter.
“The pieces are coming one by one from all over the country,” Ferguson explained. “Parts from our vendors are already starting to show up for our test article.
“Assembly of the test article in Florida starts soon.”
The CST-100 is being designed at Boeing’s Houston Product Support Center in Texas.
It is a reusable capsule comprised of a crew and service module that can carry a mix of cargo and up to seven crew members to the International Space Station (ISS) and must meet stringent safety and reliability standards.
How will the pressure vessel be manufactured? Will it involve friction stir welding as is the case for NASA’s Orion deep space manned capsule?
“There are no welds,” he informed.
“The pressure vessel is coming from Spincraft, an aerospace manufacturing company in Massachusetts.”
Spincraft has extensive space vehicle experience building tanks and assorted critical components for the shuttle and other rockets.
“The capsule is produced by Spincraft using a weld-free process. It’s made as a single piece by a proprietary spun form process and machined out from a big piece of metal.”
The capsule measures approximately 4.56 meters (175 inches) in diameter.
“The service module will be fabricated in Florida.”
The combined crew and service modules are about 5.03 meters (16.5 feet) in length.
“In two years in 2016, our CST-100 will look like the Orion EFT-1 capsule does now at KSC, nearly complete [and ready for the maiden test flight]. Orion is really coming along,” Ferguson beamed while contemplating a bright future for US manned spaceflight.
He is saddened that it’s been over 1000 days since his crew’s landing inside shuttle Atlantis in July 2011.

With Boeing’s long history in aircraft and aerospace manufacturing, the CST-100 is being designed and built as a truly commercial endeavor.
Therefore the spacecraft team is able to reach across Boeing’s different divisions and diverse engineering spectrum and draw on a vast wealth of in-house expertise, potentially giving them a leg up on commercial crew competitors like SpaceX and Sierra Nevada Corp.
Nevertheless, designing and building a completely new manned spaceship is a daunting task for anyone. And no country or company has done it in decades.
How hard has this effort been to create the CST-100? – And do it with very slim funding from NASA and Boeing.
“Well any preconceived notion I had on building a human rated spacecraft has been completely erased. This is really hard work to build a human rated spacecraft!” Ferguson emphasized.
“And the budget is very small – without a lucrative government contract as used in the past to build these kind of spacecraft.”
“Our budget now is an order of magnitude less than to build the shuttle – which was about $35 to $42 Billion in 2011 dollars. The budget is a lot less now.”
Read more about the travails of NASA’s commercial crew funding situation in Part 1.
The team size now is just a fraction of what it was for past US crewed spaceships.
“So to support this we have a pretty small team.”
“The CST-100 team of a couple hundred folks works very hard!”
“For comparison, the space shuttle had 30,000 people working on it at the peak. By early 2011 there were 11,000. We flew on STS-135 with only 4,000 people in July 2011.”

Boeing’s design philosophy is straightforward; “It’s a simple ride up to and back from space,” Ferguson emphasized to me.
Next we turned to the venerable Atlas V rocket that will launch Boeing’s proposed space taxi. But before it can launch people it must first be human rated, certified as safe and outfitted with an Emergency Detection System (EDS) to save astronauts lives in a split second in case of a sudden and catastrophic in-flight anomaly.

United Launch Alliance (ULA) builds the two stage Atlas V and is responsible for human rating the vehicle which has a virtually unblemished launch record of boosting a wide array of advanced US military satellites and NASA’s precious one-of-a-kind robotic science explorers like Curiosity, JUNO, MAVEN and MMS on far flung interplanetary voyages of discovery.
What modifications are required to man rate the Atlas V to launch humans on Boeing’s CST-100?
“We will launch on an Atlas V that’s being retrofitted to meet NASA’s NPR human rating standards for redundancy and the required levels of fault tolerance,” Ferguson explained.
“So the rocket will have all the safety NASA wants when it flies humans.”
“Now with the CST-100 you can do all that in a smaller package [compared to shuttle].”
“The Atlas V will also be modified by ULA to include an Emergency Detection System (EDS). It’s a system not unlike what Apollo and Gemini had, which was much more rudimentary but quite evolved for its day.”
“Their EDS would monitor critical parameters like pitch, roll, yaw rates, critical engine parameters. It measures the time to criticality. You know the time to criticality for certain failures is so short that they didn’t think humans could react to it in time. So it was essentially automated.”
“So if it [EDS] sensed large pitch or yaw excursions, it would self jettison. And the escape system would kick in automatically.”
The Atlas V is already highly reliable. The EDS is one of the few systems that had to be added for human flights?
“Yes.”
“We also wanted a better abort system performance to go with the two engine Centaur upper stage we elected to use instead of the single engine Centaur.”
The purpose is to shut down the Centaur engine firing [in an emergency].”
“The two engine Centaur has flown many times. But it has never flown on an Atlas V. So there is a little bit of recertification and qualification to be done by ULA to go along with that also.”
Does that require a lot of work?
“ULA doesn’t seem to think the work to be done is all that significant. There is some work to be done.”
So it’s not a showstopper. Can ULA meet your 2017 launch schedule?
“Yes.”
“Before an engine fails it vibrates. So when you talk about automated ‘Red Lines’ you have to be careful that first you “Do No Harm” – and not make the situation even worse.”
“So we’ll see how ULA does building this,” Ferguson stated.

The future of the CST-100 project hinges on whether NASA awards Boeing a contract to continue development and assembly work in the next round of funding (dubbed CCtCAP) from the agency’s Commercial Crew Program (CCP). The CCP seed money fosters development of a safe, reliable and new US commercial human spaceship to low Earth orbit as a public/private partnership.
NASA’s announcement of the CCP contract winners is expected around late summer 2014.
Based on my discussions with NASA officials, it seems likely that the agency could select at least two winners to move on – to spur competition and thereby innovation – from among the trio of American aerospace firms competing.
Besides Boeing’s CST-100, the SpaceXDragon and Sierra Nevada Dream Chaser vehicles are also in the running for the contract to restore America’s capability to fly humans to Earth orbit and the International Space Station (ISS) by 2017.
In Part 3 we’ll discuss with Chris Ferguson the requirements for how many and who will fly aboard the CST-100 and much more. Be sure to read Part 1 here.

Venus is definitely not a friendly planet for humanity. Soviet landers that arrived on the surface a few decades back were crushed pretty quickly. Its surface temperature is more than 842 degrees Fahrenheit (450 degrees Celsius) and the atmosphere is full of noxious gases.
But descending into this pressure-filled cooker is exactly what Venus Express is going to do shortly. The European Space Agency spacecraft will conclude eight years of orbital operations with an attempt to fall into the planet. The maneuvers are complicated, and there’s no guarantee they will go as planned, but ESA plans to make the plunge by the end of this year.
For the better part of a decade, Venus Express has been orbiting the planet every 24 hours, swinging in an elliptical orbit that ranges from 155 miles (250 kilometers ) to 41,010 miles (66,000 kilometers). But now the spacecraft is almost out of fuel, and will now be redirected for “experimental aerobreaking” to slow down through skimming the atmosphere.
The maneuvers will take place between June 18 and July 17, where controllers hope to gain some information about the planet’s magnetic field, solar wind, temperature and pressure.
“The campaign also provides the opportunity to develop and practice the critical operations techniques required for aerobraking, an experience that will be precious for the preparation of future planetary missions that may require it operationally,” stated Paolo Ferri, head of mission operations.
No one is sure if the spacecraft will run out of fuel, or even if it survives, but if it does its orbit could be raised to do a few more scientific observations of the planet before going into the atmosphere forever.
Venus’ Express scientific treasure trove includes measuring hydrogen atom escape in the atmosphere, checking out the planet’s clouds and tracking the slowing rotation of the planet (which is happening for reasons that are not quite clear.) It also discovered an ozone layer on the planet.

Wow! This image shows the target comet for the Rosetta mission starting to develop a tail. This bodes well for the European Space Agency spacecraft, which is on its way to study Comet 67P/Churyumov–Gerasimenko later this year to learn more about the origins of the solar system.
“It’s beginning to look like a real comet,” stated Holger Sierks, principal investigator for OSIRIS (Optical, Spectroscopic and Infrared Remote Imaging System.)
“It’s hard to believe that only a few months from now, Rosetta will be deep inside this cloud of dust and en route to the origin of the comet’s activity,” added Sierks, who is with the Max Planck Institute for Solar System Research in Germany.
The picture was one of a series taken over six weeks, between March 27 and May 4, as the spacecraft zoomed to within 1.24 million miles (two million kilometers) of the target. You can see the full animation by clicking on the image below.

The comet is now about four times as far from the Sun as the Earth is. Even from afar, the Sun’s heat is warming the comet’s ice, causing dust and vapor to carry out into space — forming the coma. The coma will develop into a long tail when the comet gets even closer to the sun.
Rosetta will be the comet’s companion as it draws closer to the sun; its closest approach will be in August 2015, when it is between the orbits of Earth and Mars. So far, the spacecraft’s 11 instruments appear to be in excellent health, ESA stated, although the agency is remaining cautious as the rendezvous date approaches. The spacecraft will begin orbital insertion activities later this month, and send out its Philae lander in November.
“We have a challenging three months ahead of us as we navigate closer to the comet, but after a 10-year journey it’s great to be able to say that our spacecraft is ready to conduct unique science at comet 67P/C-G,” stated Fred Jansen, ESA’s Rosetta mission manager.

Story updated[/caption]
NASA GODDARD SPACE FLIGHT CENTER, MD – NASA’s upcoming Magnetospheric Multiscale (MMS) mission is comprised of a quartet of identically instrumented observatories aimed at providing the first three-dimensional views of a fundamental process in nature known as magnetic reconnection. They were unveiled to greet NASA Administrator Charles Bolden on Monday, May 12, in a rare fully stacked arrangement inside the Goddard cleanroom.
Universe Today was on hand with NASA Administrator Bolden, Science Mission Chief John Grunsfeld and the MMS mission team at Goddard for a first hand inspection and up close look at the 20 foot tall, four spacecraft stacked configuration in the cleanroom and for briefings about the projects fundamental science goals.
“I’m visiting with the MMS team today to find out the status of this mission scheduled to fly early in 2015. It’s one of many projects here at Goddard,” NASA Administrator Bolden told me in an exclusive one-on-one interview at the MMS cleanroom.
“MMS will help us study the phenomena known as magnetic reconnection and help us understand how energy from the sun – magnetic and otherwise – affects our own life here on Earth. MMS will study what effects that process … and how the magnetosphere protects Earth.”
Magnetic reconnection is the process whereby magnetic fields around Earth connect and disconnect while explosively releasing vast amounts of energy.

MMS measurements should lead to significant improvements in models for yielding better predictions of space weather and thereby the resulting impacts for life here on Earth as well as for humans aboard the ISS and robotic satellite explorers in orbit and the heavens beyond.
The four identical spacecraft – which are still undergoing testing – were stacked in a rarely seen launch arrangement known affectionately as the “IHOP configuration” – because they look rather like a stack of luscious pancakes.
“MMS is a fundamental heliophysics science mission,” Craig Tooley told me at the MMS cleanroom. Tooley is MMS project manager at NASA Goddard.
“Unlike Hubble that uses remote sensing, MMS is like a flying laboratory ‘in situ’ that will capture events that are the major energy transfer from the sun’s magnetic field into our Earth’s space weather environment and magnetosphere.”
“These are called magnetic reconnection events that pump enormous amounts of energy into the plasma and the fields around Earth. It’s one of the main drivers of space weather and a fundamental physical process that is not very well understood,” Tooley explained.
“The spacecraft were built in-house here at Goddard and just completed vibration testing.”
MMS will launch atop an Atlas V rocket in March 2015 from Space launch Complex 41, Cape Canaveral Air Force Station, Florida.

The vibration testing is a major milestone and is conducted to ensure the spacecraft can withstand the most extreme vibration and dynamic loads they will experience and which occurs during liftoff inside the fairing of the Atlas V booster.
MMS is also another highly valuable NASA science mission (along with MAVEN, LADEE and others) which suffered launch delays and increased costs as a result of the US government shutdown last October 2013, Bolden confirmed to Universe Today.
“We ended up slipping beyond the original October 2014 date due to the government shutdown and [the team] being out of work for a couple of weeks. MMS is now scheduled to launch in March 2015,” Bolden told me.
“So then you are at the mercy of the launch provider.”
“The downside to slipping that far is that’s its [MMS] costing more to launch,” Bolden stated.
Each of the Earth orbiting spacecraft is outfitted with 25 science sensors to study the microphysics of three fundamental plasma processes: magnetic reconnection, energetic particle acceleration, and turbulence.
Magnetic reconnection occurs throughout our universe.
“The primary mission will last two years,” Tooley told me.
“Each spacecraft carries about 400 kilograms of fuel. There is a possibility to extend the mission by about a year based on fuel consumption.”

The spacecraft will use the Earth itself as a laboratory to unlock the mysteries of magnetic reconnection – the primary process that transfers energy from the solar wind into Earth’s magnetosphere and is responsible for geomagnetic storms.
“To understand the fundamental physics, they will fly in a pyramid-like formation and capture the magnetic reconnection events in 3-D by flying through them as they happen – that’s why we have 4 spacecraft,” Tooley explained.
“Initially they will be spaced apart by about 10 to 30 kilometers while they fly in a tetrahedron formation and scan with their booms spread out – depending on what the scientists says is the optimal configuration.”
“They fly in a highly elliptical orbit between about 7,000 and 75,000 kilometers altitude during the first half of the mission. Eventually the orbit will be extended out to about 150,000 kilometers.”
The best place to study magnetic reconnection is ‘in situ’ in Earth’s magnetosphere.
This will lead to better predictions of space weather phenomena.
Magnetic reconnection is also believed to help trigger the spectacular aurora known as the Northern or Southern lights.

Story updated[/caption]
Moscow delivered a double whammy of bad news to a broad range of US space efforts today by banning the use of Russian made rocket engines for US military national security launches and by declining to prolong cooperation on the International Space Station (ISS) – says Russia’s deputy prime minister, Dmitry Rogozin, who is in charge of space and defense industries.
Rogozin was quoted in a story prominently featured today, May 13, on the English language website of Russia Today, a Russian TV news and cultural network.
“Moscow is banning Washington from using Russian-made rocket engines, which the US has used to deliver its military satellites into orbit,” said Rogozin according to the Russia Today report.
Virtually every aspect of the manned and unmanned US space program – including NASA, other government agencies, private aerospace company’s and crucial US national security payloads – are highly dependent on Russian & Ukrainian rocketry and are clearly at risk amidst the current Ukrainian crisis as tensions continue to escalate with deadly new clashes reported today in Ukraine – with global repercussions.
The engines at issue are the Russian made RD-180 engines – which power the first stage of the venerable Atlas V rocket built by United Launch Alliance (ULA) and are used to launch a wide array of US government satellites including top secret US military spy satellites for the US National Reconnaissance Office, like NROL-67, as well as science satellites for NASA like the Curiosity Mars rover and MAVEN Mars orbiter.
The dual nozzle RD-180 engines are manufactured in Russia by NPO Energomash. Rogozin’s statement effectively blocks their export to the US.

“We proceed from the fact that without guarantees that our engines are used for non-military spacecraft launches only, we won’t be able to supply them to the US,” Rogozin said.
So although the launch of NASA science missions might preliminarily appear to be exempt, they could still be at serious risk based on a qualifier from Rogozin, pertaining to RD-180 engines already delivered.
“If such guarantees aren’t provided the Russian side will also be unable to perform routine maintenance for the engines, which have been previously delivered to the US, he added.
A ULA spokesperson told me that the company has a two year supply of RD-180 engines already stockpiled in the US.
Rogozin’s statements today are clearly in retaliation to stiffened economic sanctions imposed by the US and Western nations in response to Russia’s actions in the ongoing crisis in Ukraine and the annexation of Crimea; as I reported earlier here, here and here.
Therefore, US National Security spy satellite and NASA science launches are left lingering with uncertainty and potential disarray.
Rogozin is specifically named on the US economic sanctions target list.
He was also named by SpaceX CEO Elon Musk in his firms attempt to block the importation of the RD-180 engines by ULA for the Atlas V as a violation of US sanctions.
Federal Judge Susan Braden initially imposed a temporary injunction blocking the RD-180 imports on April 30. She rescinded that order last Thursday, May 8, after receiving written communications clarifications from the US Justice and Commerce departments that the engine import did not violate the US government imposed sanctions.
Rogozin went on to say that “Moscow also isn’t planning to agree to the US offer of prolonging operation of the International Space Station (ISS) [to 2024].
“We currently project that we’ll require the ISS until 2020,” he said. “We need to understand how much profit we’re making by using the station, calculate all the expenses and depending on the results decide what to do next.”
“A completely new concept for further space exploration is currently being developed by the relevant Russian agencies”.
NASA announced early this year the agency’s intention to extend ISS operations to at least 2024, and is seeking agreement from all the ISS partners including Russia.
Since the shutdown of the Space Shuttle program in 2011 before a replacement crew vehicle was available, American astronauts are now 100% dependent on the Russian Soyuz capsule for rides to the ISS and back.
Congress has also repeatedly slashed NASA’s commercial crew program budget, forcing at least an 18 month delay in its start up and thus continued reliance on the Soyuz for years to come at over $70 million per seat.
NASA thus has NO immediate alternatives to Russia’s Soyuz – period.
The Atlas V is also planned as the launcher for two of the three companies vying for the next round of commercial crew contracts aimed at launching US astronauts to the ISS. The commercial crew contracts will be awarded by NASA later this year.
In a previous statement regarding the US sanctions against Russia, Rogozin said that sanctions could “boomerang” against the US space program and that perhaps NASA should “deliver their astronauts to the International Space Station using a trampoline.”

“One of the main things we’re focused on is the notion of existential risk, getting a sense of what the probability of human extinction is,” said Andrew Snyder-Beattie, who recently wrote a piece on the “Great Filter” for Ars Technica.
