The Battle Against What Spaceflight Does To Your Health

Why do some astronauts come back from the International Space Station needing glasses? Eye problems are one of the largest problems that have cropped up in the last three to four years of space station science, affecting 20% of astronauts. And the astronaut office is taking this problem very seriously, pointed out Scott Smith, who leads the Nutritional Biochemistry Lab at the Johnson Space Center.

It’s one example of how extended stays in flight can alter your health. Despite NASA’s best efforts, bones and muscles weaken and months of rehabilitation are needed after astronauts spend a half-year on the space station. But in recent years, there have been strides in understanding what microgravity does to the human body — and how to fix it.

Take the vision problem, for example. Doctors believed that increased fluid shift in the head increases pressure on the optic nerve, a spot in the back of the eye that affects vision. There are a few things that could affect that:

Exercise. Astronauts are told to allot 2.5 hours for exercise on the International Space Station daily, which translates to about 1.5 hours of activity after setup and transitions are accounted for. Weight lifting compresses muscles and could force more blood into their heads. NASA installed an advanced Resistive Exercise Device on the space station that is more powerful than its predecessor, but perhaps this is also causing the vision problem, Smith said. “It’s ironic that the exercise device we’re excited about for working the muscles and bone, may hurt eyes.”
CO2 levels. This gas (which naturally occurs when humans exhale) is “relatively high” on the space station because it takes more power and more supplies to keep the atmosphere cleaner, Smith said. “Increased carbon dioxide exposure will increase blood flow to your head,” he said. If this is found to be the cause, he added, NASA is prepared to make changes to reduce CO2 levels on station.
Folate (Vitamin B) problems. Out of the reams of blood and urine data collected since before NASA started looking at this problem, they had been looking at a biochemical (nutrient) pathway in the body that moves carbon units from one compound to another. This is important for synthesizing DNA and making amino acids, and involves several vitamins and nutrients. After scientists started noticing changes in folate (a form of Vitamin B), they probed further and found an interesting thing regarding homocysteine, a type of amino acid at the heart of this one carbon pathway. It turns out those astronauts with vision issues after flight had higher (but not abnormal) levels of homocysteine in their blood before flight, as published here.

“It’s speculating, but we think that genetic differences in this pathway may somehow alter your response to things that affect blood flow into the head,” Smith said.

After finding these essentially “circumstantial” evidence of a genetic predisposition to vision issues, they proposed an experiment to look at genes associated with one carbon metabolism. “To give you an idea of the importance of this problem, we went to every crew member that’s flown to space station, or will fly to space station. We asked if they would give us a blood sample and look at their genes for one carbon meytabolism,” he said. “We approached 72 astronauts to do that, and 70 of them gave us blood, which is unheard of.”

While NASA tries to nail down what is going on with astronaut vision, the agency has made substantial progress in preserving bone density during flights — for the first time in 50 years of spaceflight, Smith added.

We mentioned the advanced Resistive Exercise Device, an orbital weight-lifting device which was installed and first used during Expedition 18 in 2008 and has been in use on the space station ever since. It’s a large improvement over the previous interim Resistive Exercise Device (iRED), which didn’t provide enough resistance, allowing some astronauts to “max out” on the device and could not further increase weightlifting loads after some weeks or months of use.

“We flew the iRED on station and the bone loss on station looked just like it did on Mir, that is, with no resistive exercise device available,” Smith said. But that changed drastically with ARED, which has twice as much loading capability. Crews ate better, maintained body weight and had better levels of Vitamin D compared to those that went before. Most strikingly, they maintained their bone density at preflight levels, as this paper shows.

While we think of bone as being cement-like and unchanging (at least until you break one!), it’s actually an organ that is always breaking down and reforming. When the breakdown accelerates, such as when you are not putting weight on it in orbit, you lose bone density and are at higher risk for fractures.

Why is unknown, except to say that the bone seems to rely on some sort of “signalling” that indicates loads or weights are being put on it. Conversely, if you are to put more weight on your bones — maybe carrying a backpack with weights on it — your skeleton would gradually get bigger to accommodate the extra weight.

While it’s exciting that the ARED is maintaining bone density, the question is whether the body can sustain two processes happening at a faster rate than before flight: the breakdown and buildup of bone. More study will be needed, Smith said, to pinpoint whether this affects the strength of the bone, which is ultimately more important than just mineral density. Nutrition and exercise may also be optimized, to further allow for better bone preservation.

That’s one of the things scientists are excited to study with the upcoming one-year mission to the International Space Station, when Scott Kelly (NASA) and Mikhail Kornienko (Roscosmos) will be one of a small number of people to do one consecutive calendar year in space. The bone “remodelling” doesn’t level off after six months, but perhaps it will closer to a year.

Smith pointed out the quality of health data has also improved since the long-duration Mir missions of the early to mid 1990s. Specific markers of bone breakdown and formation were just being discovered and implemented during that time, whereas today they’re commonly used in medicine. Between that, and the fact that NASA’s Mir data are from shorter-duration missions, Smith said he’s really looking forward to seeing what the year in space will tell scientists.

This concludes a three-part series on astronaut health. Two days ago: Why human science is so hard to do in space. Yesterday: How do we make exercises work in Zero G?

Push. Pull. Run. Lift! How Do We Make These Exercises Work In Zero G?

Here’s the thing about going to the International Space Station: No one can predict what you’ll need to do during your six-month stay there. Maybe something breaks and you need to go “outside” to fix it, in a spacesuit. Maybe you’re going to spend a day or three in a cramped corner, fixing something behind a panel.

Your body needs to be able to handle these challenges. And a big key behind that is regular exercise.

To get ready, you need to change things up frequently on Earth. Weights. Kettleballs. Pull-ups. Squats. Deadlifts. Interval training on cycles and treadmills. And more.

“Preflight, we throw everything but the kitchen sink at [astronauts],” said Mark Guilliams, a NASA astronaut health specialist who gets them ready before orbit. “We try to work as many different movements, using multiple joints and as many different planes of motion as possible “.

Some astronauts hit the gym every single day, such as the enthusiastic Mike Hopkins who did a whole YouTube series on exercising in orbit during Expeditions 37/38 earlier this year. Others prefer a few times a week. The astronauts also receive training on how to use the exercise devices they’ll have in orbit. Because time is precious up there, even when it comes to preserving your stamina.

Now imagine yourself in a weightless environment for half a year. Many of the exercises you do on the ground are impossible, unless you make certain modifications — such as strapping yourself down. Nevertheless, to make sure astronauts’ physiological systems remain at healthy levels, the space station has a range of gym equipment and the astronauts are allotted 2.5 hours for exercise daily.

That sounds like a lot, until you start factoring in other things. Setting up and taking down equipment takes time, such as when the astronauts harness themselves to the treadmill to avoid floating away. The resistance exercise machine has to be changed around for different exercises. This means that their “active” time is roughly 60 minutes for weightlifting and 40 minutes for aerobic, six days a week.

Compare that to what is recommended by the American Heart Association– 30 minutes, five days a week for light aerobic activity and two days of weightlifting — and you can see the time astronauts spend on exercise is not unreasonable. Also remember that the rest of the day, they have no gravity. Treadmill stats show the astronauts take only roughly 5,000 to 6,000 steps each day they use they use the treadmill, compared to some people’s goals of reaching 10,000 steps a day on Earth.

“When you compare the actual time the crew spends on exercise to that recommended by the AHA, it’s not a significant portion of their day that we’re asking them to participate in order for them to try and maintain their physiological health,” said Andrea Hanson, an exercise hardware specialist for the space station.

So what’s the equipment the astronauts get to use? The pictures in this article show you a range of things. There’s the Cycle Ergometer with Vibration Isolation and Stabilization System (CEVIS) — a fancy name for the exercise bike. It has remained pretty much the same since it was brought to the space station back in 2001, for Expedition 2. Its major goal is to keep an astronaut’s aerobic capacity up for demanding spacewalks, which can take place for up to eight hours at a time.

The weight device has changed over time, however. The initial Interim Resistive Exercise Device used rubber to provide the resistive force and ended up being not enough for some astronauts, who found themselves reaching the designed capability limits long before their missions ended. (Here’s a picture of it.) Astronauts stopped using it after Expedition 28 in favor of the advanced Resistive Exercise Device, which instead uses piston-driven vacuum cylinders.

“The new device actually enables us to go up to 600 pounds of loading,” Guillams said. The IRED device could only give 300 pounds of resistance. So now, even the strongest astronaut can get a challenge out of ARED, he said.

The treadmill aboard the station is also a newer one. The second-generation device allows for faster speeds, and to even save programs for each individual crew member so that they can have customized workouts when they arrive on station. (The first one, “Treadmill With Vibration Isolation And Stabilization System“, was put on to an unmanned Progress spacecraft in 2013 to burn up in the atmosphere.)

By the way, the new treadmill (T2) is called the COLBERT, or Combined Operational Load Bearing External Resistance Treadmill. It’s named after comedian Stephen Colbert, who in 2009 had his viewers vote to attach his name to a space station module when NASA held an open contest. When “Colbert” won, NASA elected to name the treadmill after him, and called the module Tranquility instead.

Whatever the treadmill’s name, the goal is to maintain astronaut bone and cardiovascular health while in orbit. A future story will deal with some of the scientific results obtained from more than a decade of ISS science in orbit.

This is part of a three-part series on astronaut health. Yesterday: Why human science is so hard to do in space. Tomorrow: How do you fight back against space health problems?

Story updated[/caption]

SpaceX CEO, founder and chief designer Elon Musk is set to unveil the manned version of his firms commercial Dragon spaceship later this week, setting in motion an effort that he hopes will soon restore America’s capability to launch US astronauts to low Earth orbit and the International Space Station (ISS) by 2017.

Musk will personally introduce SpaceX’s ‘Space Taxi’ dubbed ‘Dragon V2’ at what amounts to sort of a world premiere event on May 29 at the company’s headquarters in Hawthorne, CA, according to an official announcement this evening (May 27) from SpaceX.

“SpaceX’s new Dragon V2 spacecraft is a next generation spacecraft designed to carry astronauts into space,” according to the SpaceX statement.

The manned Dragon will launch atop the powerful SpaceX Falcon 9 v1.1 rocket from a SpaceX pad on the Florida Space Coast.

Dragon was initially developed as a commercial unmanned resupply freighter to deliver 20,000 kg (44,000 pounds) of supplies and science experiments to the ISS under a $1.6 Billion Commercial Resupply Services (CRS) contract with NASA during a dozen Dragon cargo spacecraft flights through 2016.

Musk is making good on a recent comment he posted to twitter on April 29, with respect to the continuing fallout from the deadly crisis in Ukraine which has resulted in some US economic sanctions imposed against Russia, that now potentially threaten US access to the ISS in a boomerang action from the Russian government:

“Sounds like this might be a good time to unveil the new Dragon Mk 2 spaceship that @SpaceX has been working on with @NASA. No trampoline needed,” Musk tweeted.

“Cover drops on May 29. Actual flight design hardware of crew Dragon, not a mockup,” Musk added.

The ‘Dragon V2’ is an upgraded, man rated version of the unmanned spaceship that can carry a mix of cargo and up to a seven crewmembers to the ISS.

Dragon is among a trio of US private sector manned spaceships being developed with seed money from NASA’s Commercial Crew Program in a public/private partnership to develop a next-generation crew transportation vehicle to ferry astronauts to and from the ISS by 2017 – a capability totally lost following the space shuttle’s forced retirement in 2011.

Since that day, US astronauts have been totally dependent on the Russian Soyuz capsules for ferry rides to orbit and back.

The Boeing CST-100 and Sierra Nevada Dream Chaser ‘space taxis’ are also vying for funding in the next round of contracts to be awarded by NASA around late summer 2014.

All three company’s have been making excellent progress in meeting their NASA mandated milestones in the current contract period known as Commercial Crew Integrated Capability initiative (CCiCAP) under the auspices of NASA’s Commercial Crew Program.

However, US progress getting the space taxis actually built and flying has been repeatedly stifled by the US Congress who have severely cut NASA’s budget request for the Commercial Crew Program by about half each year. Thus forcing NASA to delay the first manned orbital test flights by at least 18 months from 2015 to 2017.

The situation with regard to US dependency on Russian rocketry to reach the ISS has always been awkward.

But it finally took on new found importance and urgency from politicos in Washington, DC, since the ongoing crisis in Ukraine this year exposed US vulnerability in a wide range of space endeavors affecting not just astronaut rides to the ISS but also the launch of the most critical US national security surveillance satellites essential to US defense.

US space vulnerability became obvious to everyone when Russia’s deputy prime minister, Dmitry Rogozin. who is in charge of space and defense industries, said that US sanctions could “boomerang” against the US space program and that perhaps NASA should “deliver their astronauts to the International Space Station using a trampoline.”

Rogozin also threatened to cut off exports of the Russian made RD-180 rocket engines which power the first stage of the United Launch Alliance (ULA) Atlas V rocket used to launch numerous US National Security spy satellites.

“Moscow is banning Washington from using Russian-made rocket engines, which the US has used to deliver its military satellites into orbit,” Rogozin said at a media briefing held on May 13.

NASA is also a hefty user of the Atlas V for many of the agency’s science and communication satellites like the Curiosity Mars rover, MAVEN Mars orbiter, MMS, Juno Jupiter orbiter and TDRS.

Musk and SpaceX have also filed lawsuits against the US Air Force to legally block the importation of the RD-180 engines by ULA for the Atlas V as a violation of the US economic sanctions.

So overall, US space policy is in a murky and uncertain situation and Musk clearly aims for SpaceX to be a central and significant player in a wide range of US space activities, both manned and unmanned.

NASA Mars Lander InSight ‘Go’ For Construction

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.

Story updated[/caption]

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 Boeing CST-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.

Dangling Dextre Digs out Docked Dragon Depot prior to Station Departure

To close out their final week aboard the International Space Station, three of the six Expedition 39 crew members are completing their unloading tasks inside the docked commercial SpaceX Dragon cargo freighter and other duties while teams at Mission Control in Houston conduct delicate robotics work outside with dazzling maneuvers of the Dextre robot to remove the last external experiment from the vessels storage truck.

See a dazzling gallery of photos of Dextre dangling outside the docked Dragon depot – above and below.

On Monday, May 5, the robotics team at NASA Mission Control Center at the Johnson Space Center in Houston carefully guided Canada’s Dextre robotic “handyman” attached to the end of the 57-foot long Canadarm2 to basically dig out the final payload item housed in the unpressurized trunk section at the rear of the SpaceX Dragon cargo vessel docked to the ISS.

Dextre stands for “Special Purpose Dexterous Manipulator” and was contributed to the station by the Canadian Space Agency. It measures 12 feet tall and is outfitted with a pair of arms and an array of finely detailed tools to carry out intricate and complex tasks that would otherwise require spacewalking astronauts.

The massive orbiting outpost was soaring some 225 miles above the home planet as Dextre’s work was in progress to remove the Optical PAyload for Lasercomm Science, or OPALS, from the Dragon’s truck.

The next step is to install OPALS on the Express Logistics Carrier-1 (ELC-1) depot at the end of the station’s port truss on Wednesday.

Monday’s attempt was the second try at grappling OPALS. The initial attempt last Thursday “was unsuccessful due to a problem gripping the payload’s grapple fixture with the Special Purpose Dextrous Manipulator, or Dextre,” NASA reported.

A software patch solved the problem.

Dragon thundered to orbit atop SpaceX’s powerful new Falcon 9 v1.1 rocket on April 18, from Cape Canaveral, Fla.

OPALS uses laser light instead of radio waves to beam back precisely guided data packages to ground stations. The use of lasers should greatly increase the amount of information transmitted over the same period of time, says NASA.

The science experiments carried aboard Dragon are intended for research to be conducted by the crews of ISS Expeditions 39 and 40.

Robotics teams had already pulled out the other payload item from the truck, namely the HDEV imaging suite. It is already transmitting back breathtaking real time video views of Earth from a quartet of video cameras pointing in different directions mounted on the stations exterior.

The SpaceX CRS-3 mission marks the company’s third resupply mission to the ISS under a $1.6 Billion 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.

After spending six months in space, Station Commander Koichi Wakata from Japan as well as NASA astronaut Rick Mastracchio and Russian cosmonaut Mikhail Tyurin will be departing the station in a week aboard their Soyuz TMA-11M spacecraft on May 13 at 6:33 p.m. EDT.

They are scheduled to land some 3.5 hours later in the steppes of Kazakhstan at 9:57 p.m. (7:57 a.m. Kazakh time on May 14). The events will be carried live on NASA TV.

To prepare for the journey home, the trio also completed fit checks on their Russian Sokol launch and entry suits on Monday.

Meanwhile Dragon is also set to depart the station soon on May 18 for a parachute assisted splashdown and recovery by boats in the Pacific Ocean west of Baja California.

Dragon has been docked to the station since arriving on Easter Sunday morning, April 20.

It was grappled using Canadarm 2 and berthed at the Earth facing port of the Harmony module by Commander Wakata and flight engineer Mastracchio while working at the robotics work station inside the seven windowed domed Cupola module.

For the return trip, the Expedition 39 crew is also loading Dragon with precious science samples collected over many months from the crews research activities as well as trash and no longer needed items.

Story updated[/caption]

A US Federal Court has now issued a preliminary injunction that blocks the purchase and importation of Russian rocket engines by United Launch Alliance (ULA) for its Atlas V rocket used in National Security launches for the US Air Force after a filing by SpaceX. But what are the implications?

The US Federal Court of Federal Claims order was issued late Wednesday, April 30, by US Judge Susan G. Braden of the US Court of Federal Claims. The court order is in response to a protest filed by SpaceX against ULA and the US Air Force relating to the uncontested $11 Billion “block buy” launch contract purchase in December of 36 rocket cores for US National Security launches and is also related to US sanctions imposed after Russia’s recent actions in Ukraine and seizing and annexing the Crimea.

The temporary injunction marks a big win for SpaceX but immediately throws future National Security spy satellite and NASA science launches into uncertainty and potential disarray as I reported previously – here and here.

As I posted here last Friday, April 25, SpaceX CEO Elon Musk declared his firms intent to file suit against ULA and the Air Force on Monday, April 28 to break the launch monopoly.

Judge Braden’s injunction followed barely two days later.

Musk said the recent ‘block buy’ launch contract was unfair in blocking SpaceX from competing for launches of surveillance satellites, would cost taxpayers billions of extra dollars in coming years and should be recompetited.

“The national security launches should be put up for competition and they should not be awarded on a sole source, uncompeted basis,” Musk said at the April 25 briefing at the National Press Club in Washington, DC.

ULA quickly vowed today that they will respond to resolve the injunction and further stated that “This opportunistic action by SpaceX … ignores the potential implications to our National Security.”

Federal Judge Braden’s order specifically states the following; “The preliminary injunction prohibits the United States Air Force and United Launch Alliance, from making any purchases from or payment of money to NPO Energomash or any entity, whether governmental, corporate or individual, that is subject to the control of Deputy Prime Minister Rogozin.”

“IT IS SO ORDERED,” wrote Braden.

The engines at the heart of the Federal preliminary injunction are the RD-180 liquid fueled engines which power ULA’s Atlas V rocket and are manufactured in Russia by NPO Energomash – which is majority state owned by the Russian Federation and subject to the control of Russian Deputy Prime Minister Rogozin, who is specifically named on the US economic sanctions target list.

In response, Rogozin said that sanctions could “boomerang” against the US space program. He said that perhaps NASA should “deliver their astronauts to the International Space Station using a trampoline.”

Thanks to the utter folly of US politicians in shutting down the Space Shuttle program before a replacement crew vehicle was available and repeatedly slashing NASA’s commercial crew budget, American astronauts are now 100% dependent on the Russian Soyuz capsule for rides to the ISS and back for several more years ahead.

NASA has NO immediate alternatives to Russia’s Soyuz – period.

The rocket engine injunction is just the latest fallout impacting a vast swath of US space programs from National Defense to NASA stemming from the dangerously escalating crisis between Ukraine and the Russian Federation in the worst confrontation with the West since the Cold War era.

In response to the worsening Ukraine crisis, Western nations have instituted waves of increasingly harsh economic sanctions against Russia and several key members of the Russian government.

Judge Braden’s injunction stands until she receives clarification otherwise from US government entities that the engine purchase is not covered by the Federal government santions.

The order remains in effect “unless and until the court receives the opinion of the United States Department of the Treasury, and the United States Department of Commerce and United States Department of State, that any such purchases or payments will not directly or indirectly contravene Executive Order 13,661.”

ULA issued a swift statement today – received by Universe Today – from ULA’s general counsel Kevin G. MacCary, in response to Judge Braden’s preliminary injunction.

“ULA is deeply concerned with this ruling and we will work closely with the Department of Justice to resolve the injunction expeditiously. In the meantime, ULA will continue to demonstrate our commitment to our National Security on the launch pad by assuring the safe delivery of the missions we are honored to support.”

“SpaceX’s attempt to disrupt a national security launch contract so long after the award ignores the potential implications to our National Security and our nation’s ability to put Americans on board the International Space Station.”

The Atlas V rocket, powered by the Russian made RD-180 engines, will also be used as the launch vehicle by two of the three companies vying for the next round of commercial crew contracts aimed at launching US astronauts to the ISS. The contracts will be awarded by NASA later this year.

“This opportunistic action by SpaceX appears to be an attempt to circumvent the requirements imposed on those who seek to meet the challenging launch needs of the nation and to avoid having to follow the rules, regulations and standards expected of a company entrusted to support our nation’s most sensitive missions,” said ULA.

ULA is a joint venture between aerospace giants Boeing and Lockheed Martin, formed in 2006. It has conducted 81 consecutive launches with 100% mission success – including many NASA science and mission probes like Orion EFT-1, Curiosity, MAVEN, TDRS and more.

Judge Braden furthermore made clear that her order did not include prior RD-180 engine purchases.

“The scope of this preliminary injunction does not extend to any purchase orders that have been placed or moneys paid to NPO Energomash prior to the date of this
Order [April 30, 2014].”

ULA has a two year contingency supply of the RD-180’s and blueprints to begin production, if needed.

However in the event of a cutoff by Russia or US court injuncions, it would take ULA at least three to five years to start and certify RD-180 engine production somewhere in the US, a ULA spokesperson told me recently at Cape Canaveral.

This possibly leaves a 1 to 3 year gap with no Atlas V 1st stage engine supply.

SpaceX claims they can fill part of the launch gap. But their Falcon rockets are not yet certified for National Security launches.

“So far we are most of the way through the certification process. And so far there have been zero changes to the rocket. Mostly it’s just been a paperwork exercise.”

“In light of international events, this seems like the wrong time to send hundreds of millions of dollars to the Kremlin,” said Musk during the April 25 press briefing at the National Press Club in Washington, DC.

Striking a Buzz Lightyear-like pose above is the winning design for NASA’s Z-2 spacesuit prototype. The version, called “technology”, was by far the popular vote in an online contest the agency held to choose between three prototypes, garnering 62% of 233,431 votes.

While this will never be used in space, NASA said the next-generation prototype will be useful in helping design future spacesuits. And this prototype will go through a “test campaign” that includes vacuum tests, pool tests in NASA’s Neutral Buoyancy Laboratory and in an area at the Johnson Space Center that simulates the surface of Mars.

“With the agency laser focused on a path to Mars, work to develop the technologies astronauts one day will use to live and work on Mars has already begun. Each iteration of the Z-series will advance new technologies that one day will be used in a suit worn by the first humans to step foot on the Red Planet,” NASA stated.

To learn more about the suit and the differences from its predecessor, the Z-1, check out this recent Universe Today article.

SpaceX CEO Elon Musk Sues Government to Break US Air Force’s National Security Launch Monopoly

SpaceX CEO Elon Musk announces lawsuit protesting Air Force launch contracts while speaking at the National Press Club in Washington, DC on April 25, 2014
Story updated[/caption]

Elon Musk, CEO and founder of the upstart commercial launch venture SpaceX, announced at a press conference today, Friday, April 25, that SpaceX is filing suit against the Federal Government to protest and break the US Air Force’s awarding of lucrative launch contracts for high priority national security satellites to a sole rocket provider – United Launch Alliance (ULA) – on a non competitive basis.

The gloves are officially off in the intensely mounting duel over multibillion dollar Air Force military launch contracts between SpaceX and ULA.

“The official protest document will be available Monday, April 28th at www.freedomtolaunch.com and will be filed with the United States Court of Federal Claims in Washington, D.C.,” said SpaceX in an official statement.

Musk said the Air Force launch contract with ULA amounted to a continuing monopoly, was unfair by blocking SpaceX from competing for launches of surveillance satellites and would cost taxpayers billions of extra dollars in coming years.

“What we feel is that this is not right – that the national security launches should be put up for competition and they should not be awarded on a sole source, uncompeted basis,” said Musk at the briefing called on short notice and held at the National Press Club in Washington, DC.

The latest Air Force launch contract dated to December 2013 guarantees the “block buy” purchase of 36 rocket cores from ULA for national security launches for the DOD, NRO and other government agencies, at a significantly reduced cost compared to earlier contracts.

A further 14 cores were to be awarded on a competitive basis, including bids from SpaceX and others who seek to gain Air Force certification. Several of those launch awards have now been deferred indefinitely.

ULA is a joint venture between aerospace giants Boeing and Lockheed Martin, formed in 2006, that has launched over 80 satellites to orbit and beyond including many NASA science and mission probes like Orion EFT-1, Curiosity, MAVEN, TDRS and more.

It manufactures the Delta IV and Atlas V unmanned, expendable rocket families that are currently the only boosters certified to launch the high value military payloads at issue in the lawsuit announced on Friday by Musk.

The newest versions of the Delta and Atlas rockets – known as EELV’s (Evolved Expendable Launch Vehicles) have had nearly flawless records of success since being introduced some dozen years ago by the companies individually, before the ULA merger.

Musk wants his company’s newer and he says much cheaper Falcon 9 and Falcon Heavy rockets to be certified by the Air Force and included in the competition for launch contracts.

To date the Falcon 9 has launched only 9 times. Only four of those were in the new and more powerful configuration needed by the Air Force.

Musk is not asking that the launches be awarded outright to SpaceX. But he does want the Air Force contract cancelled and re-competed.

“We’re just protesting and saying that the launches should be competed,” Musk said.

“If we compete and lose that’s fine. But why were they not even competed? That just doesn’t make sense.”

“So far we are most of the way through the certification process. And so far there have been zero changes to the rocket. Mostly it’s just been a paperwork exercise.”

“Since this is a large multiyear contract, why not wait a few months for the certification process to complete. And then do the competition. That seems very reasonable to me.”

Musk said it costs four times more to launch ULA’s Delta or Atlas rocket vs. a SpaceX Falcon rocket.

“The ULA rockets are basically four times more expensive than ours. So this contract is costing US taxpayers billions of dollars for no reason.”

“Each launch by ULA costs American taxpayers roughly $400 million per launch. They are insanely expensive. I don’t know why they are so expensive.”

The Falcon 9 lists for about $60 Million per launch, but rises to about $100 million after the certification costs are included, Musk explained.

“So yes the certification does make our Falcon 9 rocket more expensive. But not 400% more expensive.”

“Our rockets are 21st century design,” said Musk to obtain the most efficiency. He said ULA’s designs date back to the 90s and earlier with heritage hardware.

To date the Falcon 9 has already been used three times under a $1.6 Billion contract with NASA to launch the private SpaceX Dragon resupply vessel to the International Space Station (ISS) – most recently a week ago during the April 18 blastoff of the SpaceX CRS-3 mission from Cape Canaveral.

It is also being used to launch highly expensive communications satellites like SES-8 and Thaicom-6 for private companies to geostationary orbits.

“It just seems odd that if our vehicle is good enough for NASA and supporting a $100 billion space station, and it’s good enough for launching NASA science satellites, for launching complex commercial geostationary satellites, then there’s no reasonable basis for it not being capable of launching something quite simple like a GPS satellite,” said Musk.

“Our only option is to file a protest.”

Furthermore as I wrote here in a prior article, US National Security launches are now potentially at risk due to the ongoing crisis between Russian, Ukraine and Crimea because the RD-180 first stage engines powering the Atlas V are designed and manufactured in Russia by NPO Energomash, majority owned by the Russian Federation.

“The head of the Russian space sector, Dmitry Rogozin, was sanctioned by the White House in March 2014 in the wake of Russia’s aggression in Ukraine,” says SpaceX.

The RD-180 engine supply could be cut off in a worst case scenario if economic sanctions against Russia are increased by the Western allies.

ULA has a two year contingency supply of the RD-180’s and blueprints to begin production, if needed.

However in the event of a cutoff, it would take at least three to five years to start and certify RD-180 engine production somewhere in the US, a ULA spokesperson told me recently at Cape Canaveral.

This possibly leaves a 1 to 3 year gap with no Atlas V 1st stage engine supply.

The Delta IV rockets and engines by contrast are manufactured in the US.

“In light of international events, this seems like the wrong time to send hundreds of millions of dollars to the Kremlin,” said Musk.

“Yet, this is what the Air Force’s arrangement with ULA does, despite the fact that there are domestic alternatives available that do not rely on components from countries that pose a national security risk.”
