Space Policy Events for March 24-28, 2014

Space Policy Events for March 24-28, 2014

The following events may be of interest in the week ahead.  The House and Senate are in session and, yes, there’s another chance for wintry weather here in the DC area on Tuesday, so check to be sure that any events you’re interested in on Tuesday or Wednesday are still on track.  (It’s not supposed to be too bad this time, though.)

During the Week

With the tense U.S.-Russian relationships resulting from the situation in Ukraine commanding attention, perhaps the most interesting event this week will be the launch of two Russians and an American to the International Space Station (ISS) from Kazakhstan on Tuesday.  There is no outward sign of cracks in the ISS partnership, so the expectation is that this will be as routine as a launch ever can be.   Launch is at 5:17 pm EDT; docking is just under 6 hours later at 11:04 pm EDT.

Meanwhile, back here in the States, congressional hearings on the budget for science agencies in general and NASA specifically kick off before the House Science, Space and Technology Committee on Wednesday and Thursday respectively.  NASA’s hearing will come a day after a forum at NASA Headquarters with an update on its Asteroid Initiative — the “initiative” is the Asteroid Redirect Mission (ARM) plus the Asteroid Grand Challenge plus the extra money in NASA’s Science Mission Directorate to augment the search for asteroids — on Wednesday afternoon.  NASA astronaut Karen Nyberg who recently was aboard the ISS will speak there.  She and Luca Parmitano — the ESA astronaut whose helmet filled with water during that EVA last year — will speak at the University of Maryland, College Park, MD, later that day about their recent tour of duty aboard ISS.

Lots of other interesting events are on tap, too.   The list below has everything we know about as of Sunday afternoon.

Scientists using NASA-NSF Telescope Discover Gravitational Waves from Big Bang – UPDATE

Scientists using NASA-NSF Telescope Discover Gravitational Waves from Big Bang – UPDATE

UPDATE, February 2, 2015:  After further analysis, scientists involved in this “discovery” retracted it.    The Associated Press quotes Brian Keating as saying “we’re essentially retracting the claim” in a new paper.  “It’s disappointing … but it’s important to know the truth.

ORIGINAL STORY, March 20, 2014: Scientists using a telescope in Antarctica equipped with sensors developed by NASA announced on Monday that they discovered evidence of gravitational waves produced by the Big Bang that many believe created our universe.

Understanding the origin and evolution of the universe is a scientific quest dating back centuries.  Today, most scientists believe an event called the Big Bang started it all, though what created the Big Bang is unknown and only theories exist about what happened in the first moments afterwards.

Based on observations from NASA’s Hubble Space Telescope, the universe is calculated to be 13.8 billion years old and NASA’s Hubble and Spitzer space telescopes have peered back through about 13.3 billion of those years.  NASA’s COBE and WMAP satellites as well as the European Space Agency’s (ESA’s) Planck mission have studied light – the Cosmic Microwave Background (CMB) – that originated from an even younger universe and began to stream through space 380,000 years after the Big Bang.

What happened before that remains a mystery.  One theory is that in the fractions of a second after the Big Bang, a period of “inflation” took place where theoretical particles called “inflatons” pushed space-time apart.  Eventually stars, galaxies, planets and the other objects and phenomena observable today formed.  Some scientists theorize that the inflatons continued to form new universes in a process dubbed “eternal inflation” with “infinite pocket universes” creating a multiverse.  Andrei Linde of Stanford was quoted by New Scientist as saying that “[i]f inflation is there, the multiverse is there.”

The findings from the BICEP2 telescope in Antarctica announced this week by the Harvard-Smithsonian Center for Astrophysics (CfA) relate to an infinitesimal period of time – a trillionth of a trillionth of a trillionth of a second – after the Big Bang.  Inflation theory posits that the events occurring at that time created gravitational waves that can still be detected today.  The observations with BICEP2 support that theory.

BICEP2 found a characteristic swirly pattern in the polarization of the light left over from the Big Bang (the CMB) that could only be caused by gravitational waves. Waves of light are polarized when they tend to wiggle in one particular direction.  Gravitational waves – ripples in space-time caused by the motion of massive objects like those being flung outward during the violent expansion of inflation – would polarize light as they swept through the universe.  The Harvard-Smithsonian CfA announcement said the BICEP2 data “represent the first images of gravitational waves, or ripples in space-time.”

BICEP2 is a radio telescope funded by NSF, which also runs the South Pole Station where BICEP2 is located.  NASA’s Jet Propulsion Laboratory (JPL) developed the superconductor-based BICEP2 detectors.  Jamie Bock, who has joint appointments with JPL and Caltech, is co-director of the project and said that it already was known that the Big Bang produced density waves, but these observations are the first to show that gravitational waves were also produced.

The BICEP2 findings support inflation theory, but remain to be corroborated by subsequent studies, a sine qua non of the scientific process.  Nonetheless, the astrophysics community is energized.

In the meantime, assuming the result holds, the implications are tantalizing: it solidifies the theory of inflation and greatly narrows the pool of inflation models that can be correct. Furthermore, it again proves Einstein’s prediction of gravitational waves.

BICEP2 is not the only telescope searching for signs of inflation.  Among the others is NSF’s Laser Interferometer Gravitational Wave Observatory (LIGO), a large ground-based experiment designed to detect gravitational waves directly.  Work is now being done to upgrade the detectors in the facility and “Advanced LIGO” should begin operations this year.  The Laser Interferometer Space Antenna (LISA) is a potential NASA-ESA mission that would seek to detect gravitational waves directly using three separated spacecraft.  It received a relatively low priority (priority 3) in the National Research Council’s most recent Decadal Survey for astrophysics because the technology is not mature.  ESA plans to launch a technology demonstration for such a mission, LISA Pathfinder, next year.

BICEP2 is an international collaboration involving 11 institutions: Caltech, JPL, UC San Diego, Harvard, NIST Boulder, Stanford, University of British Columbia, University of Chicago, University of Minnesota, University of Toronto and University of Wales Cardiff.  BICEP stands for Background Imaging of Cosmic Extragalactic Polarisation.  This was the second phase of the BICEP experiment, hence the designation BICEP2.

Yutu Awakes Again, But Mechanical Problem Remains Unresolved

Yutu Awakes Again, But Mechanical Problem Remains Unresolved

China’s Yutu lunar rover awakened from its third period of dormancy on Friday, but its mechanical problems remain unresolved.  It was designed to survive for three of these lunar day/night cycles so in many respects can be considered a success, even if not a full success.

China’s official Xinhua news agency published a charming article about the rover yesterday, quoting from many messages on China’s version of Twitter (Sina Weibo) that humanize the robot.   Chinese space officials say they do not know who operates the “Lunar Rover Yutu” account, but the author tweets as though it is Yutu’s own voice.  Xinhua reported that a message was posted on the day Yutu woke up, March 14, which is Pi Day (named after the mathematical constant pi, which begins 3.14) — humorously asking “Any carrot pi for me?”   The carrot reference is because Yutu is named after a pet rabbit that accompanies China’s mythological goddess of the Moon, Chang’e.

Yutu was designed to operate during the 14 days of lunar sunlight and be dormant (sleep) for the 14 days of bitterly cold lunar night.

The article had little hard news in it, though, and adds to the confusion about what exactly is wrong with Yutu.  It is a rover that carries scientific equipment intended to test different sites on the lunar surface as it treks across the Moon.  Just before it entered this third period of dormancy, Chinese officials revealed the nature of the rover’s previously reported mechanical failure was a malfunctioning control circuit in its driving unit.  That meant the rover cannot rove.  Its instruments apparently are functioning normally, however.

This most recent Xinhua article, though, says that “the ailing rover will continue to work, roaming on the moon while commanded by the mission control center.”  That implies that it is, in fact, still able to move.

In a presentation in Washington, DC to the National Research Council’s Space Studies Board on March 3, Wu Ji of the Chinese Academy of Science’s National Space Science Center said Yutu is “useless” without the ability to move since its purpose is to test lunar regolith in different locations.

Meanwhile, the Chinese media have not said very much about the Chang’e-3 lander that delivered Yutu to the surface and has its own scientific instruments.  It is a stationary lander that was designed to work for one year.   Chang’e-3 and Yutu landed on the Moon on December 14, 2013 Eastern Standard Time.   They are China’s first spacecraft designed to make a survivable landing on the Moon. Future lunar probes are planned, including a sample return mission (Chang’e 5)  in 2017.

Hagel Says Ukraine Situation Will Lead to Review of Use of Russian Rocket Engines

Hagel Says Ukraine Situation Will Lead to Review of Use of Russian Rocket Engines

Secretary of Defense Chuck Hagel told a House appropriations subcommittee today that the situation in Ukraine will lead to a review of the U.S. use of Russian rocket engines.  The Atlas V, used for many national security space launches, uses Russian RD-180 engines.

During a hearing before the defense subcommittee of the House Appropriations Committee today, Hagel was asked by Rep. Robert Aderholt (R-AL), whether the Ukrainian situation demonstrates that it is time for “joint Air Force, NASA funding to develop additional capabilities for making powerful rocket engines here in the U.S.”?

Hagel replied “You’re obviously referring to the relationship we have with the Russians on the rocket motors and, well, I think this is going to engage us in a review of that issue.  I don’t think there’s any question about that.”

Aderholt represents Alabama’s 4th district, close to Huntsville and NASA’s Marshall Space Flight Center, which specializes in the development of rockets and rocket engines.  It also is close to Decatur, home to United Launch Alliance’s (ULA’s) manufacturing facilities for the Atlas V and Delta IV rockets.  ULA provides launch services to the U.S. government primarily for national security space satellites using those two rockets, which collectively are called Evolved Expendable Launch Vehicles (EELVs).  Issues surrounding competition for U.S. government launch services using EELVs versus “new entrants” like SpaceX are a hot topic today.

Elon Musk, founder and Chief Engineer of SpaceX,  made the case at a congressional hearing last week for phasing out the Atlas V because of its dependence on Russian engines and using his “made in America” Falcon rockets instead.  At the same hearing, ULA’s Michael Gass stressed that ULA has a two-year supply of the RD-180 engines and is confident it could produce more on its own if the supply from Russia was disrupted.

Until today, U.S. officials have downplayed the effects on U.S. space relationships of the geopolitical situation in Ukraine.  Hagel’s statement is the first public sign that it is causing second thoughts about U.S. reliance on Russian space hardware.  Orbital Sciences Corporation’s Antares rocket also relies on Russian and Ukrainian hardware and, of course, the United States is completely dependent on Russia for taking crews to and from the International Space Station since the space shuttle program was terminated in 2011.

NASA's Jim Green Worried About LRO, Comments on Cassini Extension and Europa

NASA's Jim Green Worried About LRO, Comments on Cassini Extension and Europa

NASA Planetary Science Division Director Jim Green told a NASA advisory subcommittee today that funding for operations of the Lunar Reconnaissance Orbiter (LRO) is not assured for the rest of FY2014.

LRO is part of NASA’s Lunar Quest program and Congress provided no funds for it in FY2014.  The Lunar Atmosphere and Dust Environment Explorer (LADEE) also is part of Lunar Quest, but remaining funds in FY2014 are sufficient for that mission, which has a short lifetime.

LRO, however, can continue operating in lunar orbit for some time yet.   Launched in 2009, it is providing detailed images of the lunar surface.   Green hopes to get permission to shift funds within his budget through NASA’s FY2014 operating plan to maintain LRO operations.  Operating plans detail how NASA plans to spend the money Congress appropriated.  Historically, Congress acquiesces to comparatively minor changes such as this, although last year Congress and the Administration waged a multi-month battle over how to spend FY2013 funds.  That funding was significantly impacted by the sequester and two congressionally-imposed rescissions and disagreement arose about priorities.

NASA’s FY2014 operating plan was due to be submitted to Congress within 45 days of enactment of the FY2014 Consolidated Appropriations Act on January 17.   Green told the NASA Advisory Council’s Planetary Science Subcommittee today that it had not yet been submitted to the best of his knowledge.

He said he did not believe it was Congress’s intent to cancel LRO and is optimistic that funds will be found.   In addition, however, LRO also must successfully emerge from NASA’s “Senior Review” process where scientists who want to extend a spacecraft’s mission after its primary mission is completed must go through a peer review process to evaluate the mission’s scientific merit to determine if it warrants the additional costs to continue operations.  LRO is one of seven missions that will be considered by the 2014 planetary science Senior Review in an era of tight funding, but Green sounded optimistic.   If LRO is recommended for continuation by the Senior Review and money is found, it will be shifted into NASA’s Discovery line of planetary missions since the Lunar Quest line no longer exists.

NASA’s FY2015 budget request for planetary science is $1.280 billion, less than the $1.345 billion appropriated for FY2014.

Another mission slated for consideration by the Senior Review is Cassini.   Orbiting Saturn since 2004, Cassini continues to send back valuable information not only about Saturn itself, but its moons, including Titan.   Cassini’s mission definitely will end in 2017 because it will run out of fuel and NASA wants to intentionally deorbit it into Saturn’s atmosphere so it does not contaminate other nearby bodies like Titan.  But that is three years from now and Cassini scientists want to extend operations until then.

Wording in a document released by the White House Office of Management and Budget (OMB) explaining NASA’s FY2015 budget request implied that a decision to curtail operations of the Stratospheric Observatory for Infrared Astronomy (SOFIA), a joint aircraft-based astronomy project by NASA and its German counterpart, DLR, was made in order to ensure funding for Cassini operations.  Green insisted that was a matter of poor writing, however, not fact.   SOFIA is part of NASA’s astrophysics program and ordinarily each NASA science discipline – astrophysics, planetary science, heliophysics and earth science – must solve budgetary problems within their own budgets rather than taking money from others.

Green passionately explained today that there was no “horse-trading” between NASA’s astrophysics and planetary science offices as some suggest: “Don’t buy into that.”  Budget pressures are everywhere, he insisted, and each of NASA’s science disciplines still must find its own solutions.  Every planetary science program subject to the 2014 Senior Review must make its best case and NASA will match that peer-reviewed priority ranking to budgetary resources, Green said, adding that Cassini advocates should take nothing for granted – “there is no substitute for an excellent proposal.”

In addition to LRO and Cassini, the other five missions that will be considered by the Senior Review for extended operations are associated with Mars exploration:  the Mars rover Opportunity; the Mars rover Curiosity; the Mars orbiter Odyssey; another Mars orbiter MRO; and a NASA instrument (Aspera-3) on Europe’s Mars Express (MEX), another Mars orbiter.

Green discussed many other aspects of NASA’s FY2015 budget request, including the $15 million designated for studies of a mission to Jupiter’s moon Europa.   He excitedly noted that this was the first time that the Obama Administration is requesting funds for Europa studies, but repeated what other NASA officials have said – they want to determine if major scientific objectives could be met with a mission costing NASA no more than $1 billion.   (Congress added money for Europa in FY2013 and FY2014, but the Administration did not request any.) The original cost estimate for a Europa mission was $4.7 billion.  Scientists at the Jet Propulsion Laboratory devised a different type of mission dubbed Europa Clipper that had much less scientific capability, but could still provide important scientific data, for about $2 billion.   Cutting that cost in half will be a challenge.  International partnerships are one possibility, but Green said that based on past experience it would not be a 50-50 split so the $1 billion that NASA could provide would still represent the preponderance of the cost.

The $15 million for Europa in the FY2015 budget request is only for that one year.   No funding is requested for future years, so it is not a “new start” indicating that the Obama Administration is committed to executing such a mission within a definitive time frame.

Funding for Europa Mission Ephemeral in NASA Budget

Funding for Europa Mission Ephemeral in NASA Budget

NASA requested $15 million in FY2015 for a robotic mission to Jupiter’s moon Europa, but as the detailed budget documents released late yesterday illustrate, that is a one-year request only.   The 5-year budget plan included in the detailed document includes no funding beyond FY2015.

NASA’s 713-page detailed FY2015 budget request was posted on NASA’s website yesterday.  An overview was released last week and the only new flight project initiative announced was $15 million for a mission to Europa, whose icy crust is thought to cover a liquid ocean with the tantalizing implication that microbial life might exist there.

A mission to Europa was the second priority for a large mission in the National Research Council’s 2011 Decadal Survey for planetary science, losing out to a campaign of Mars missions leading to a Mars sample return in part because of its $4.7 billion pricetag.

Since then, scientists at the Jet Propulsion Laboratory (JPL) have been working to reduce the cost (and consequently the scientific return) of the mission.  The “Europa Clipper” concept would cost about $2 billion.  Though less than half the original estimate, it is still in the “flagship” range of NASA science missions – the most expensive category – and the Obama Administration has not been willing to commit to a mission of that magnitude.

Some influential members of Congress, however, are quite partial to a Europa mission and Congress added money for it in the FY2013 and FY2014 budgets.  Rep. John Culberson (R-TX) and Adam Schiff (D-CA) who serve on the House Appropriations Commerce-Justice-Science (CJS) Subcommittee that funds NASA, and Rep. Lamar Smith (R-TX), who chairs the House committee that authorizes NASA activities, are among the supporters of a Europa mission.

In FY2013, Congress added $75 million, or about $69 million after reductions for the sequester and two rescissions required by the law.  For FY2014, Congress added $80 million.

As NASA officials point out, however, they cannot build a mission based on promises or expectations that Congress will add money year after year after year. What is needed is approval for a “new start” program that is factored into NASA’s long range budget plans, something that needs Administration acquiescence.

When NASA Administrator Charlie Bolden released an overview of the budget request for FY2015 last week, it initially appeared that Europa had achieved the “new start” threshold when he said the request included $15 million for a Europa mission.  As details released yesterday prove, however, that is only for one year, FY2015.  It is not funding for a new program expected to last many years until launch in the 2020s.  The projected future budget, or “runout,” for FY2016 and beyond is zero.

Speaking at the American Astronautical Society’s Goddard Memorial Symposium on Wednesday (March 5), Bolden said the agency is “committed” to launching a mission to Europa in the decade of the 2020s, but he is targeting the cost at about $1 billion.  That is half of the Europa Clipper concept.  He acknowledged that it will be difficult to design a mission for that cost.  Later at the AAS conference, NASA Science Mission Directorate (SMD) chief John Grunsfeld indicated that NASA will not be able to spend all the $80 million provided in the FY2014 budget before the end of FY2014 because the budget was finalized so late and some of that will be carried over into FY2015.   If Congress approves the $15 million requested for FY2015, however, that still is not enough to move the project forward, he said, and the focus remains on studies.   He plans to release a Request for Information (RFI) soon to solicit input on what could be accomplished with a $1 billion-class mission. That would fit within SMD’s “New Frontiers” category of competed missions that are intended to be initiated every three years, but not enough for a flagship mission.

Soyuz TMA-10M Cleared for Landing Tonight – UPDATE

Soyuz TMA-10M Cleared for Landing Tonight – UPDATE

UPDATE:  Soyuz TMA-10M landed as scheduled.   Bad weather limited the number of helicopters participating in the recovery effort to four instead of 12 and the folks who normally provide live video of the landing were left behind.  So no live audio/video of the descent, but NASA reported that the crew landed on time at 11:24 pm EDT.

ORIGINAL STORY:  Soyuz TMA-10M is on track for landing tonight at 11:24 pm Eastern Daylight Time (EDT) despite inclement weather at the landing site in Kazakhstan.

The three International Space Station (ISS) crew members — Oleg Kotov, Sergey Ryazanskiy and Mike Hopkins — closed the hatches between the ISS and their Soyuz transport vehicle at 4:58 pm EDT, slightly after the scheduled time of 4:45 pm EDT.   Undocking is expected at 8:02 pm EDT.

Whether the landing would take place tonight or be postponed until later this week was up in the air earlier today because of the snowy, windy, frigid weather.

Three ISS crew members — Japan’s Koichi Wakata, NASA’s Rick Mastracchio and Russia’s Mikhail Tyurin — remain aboard the ISS.  Wakata assumed command of the ISS yesterday, the first Japanese to hold that position.  Another three-man crew is scheduled to launch in about two weeks to restore ISS to its typical 6-person complement.

NASA TV coverage of the undocking begins at 7:45 pm EDT, and of the landing at 10:15 pm EDT.

Bad Weather Might Delay Soyuz TMA-10M Landing Tonight

Bad Weather Might Delay Soyuz TMA-10M Landing Tonight

Bad weather in Kazakhstan could lead to a postponement of the scheduled landing of Soyuz TMA-10M late tonight Eastern Daylight Time (EDT).   A go/no-go decision is expected late this afternoon.

Soyuz TMA-10M with cosmonauts Oleg Kotov and Sergey Ryazanskiy and astronaut Mike Hopkins is scheduled to undock from the International Space Station at 8:02 pm EDT and land at 11:24 pm EDT (9:24 am Tuesday local time at the landing site).  NASA photographer Bill Ingalls, who is in Kazakhstan to cover the landing, tweeted this morning that the helicopter he was in was returning to Karaganda because of the bad weather.

 

 

NASA Johnson Space Center spokesman Josh Byerly said that the landing commission will meet at 4:00 pm EDT today to decide whether or not to proceed with the landing.   If it must be postponed, the landing “would be later this week most likely,” he added, rather than tomorrow.

If the landing goes ahead tonight, NASA TV coverage is scheduled as follows:

  • TV coverage begins at 4:30 pm EDT for hatch closure (which is at 4:45 pm EDT)
  • TV coverage begins at 7:45 pm EDT for undocking (which is at 8:02 pm EDT)
  • TV coverage begins at 10:15 pm EDT for landing (which is at 11:24 pm EDT)

Space Policy Events for March 10-14, 2014

Space Policy Events for March 10-14, 2014

The following events may of interest in the week ahead.  The House and Senate are in session.  As hard as it is to believe, Washington, DC may get another (thankfully brief) taste of winter Wednesday night into Thursday.  If the forecast holds, be sure to check to see if any Thursday events in DC are still on track.

During the Week

Of geopolitical as well as space interest, two Russian cosmonauts and an American astronaut are due to land in Kazakhstan tomorrow night (Monday) Eastern Daylight Time (EDT).  U.S. officials insist that International Space Station (ISS) operations are not being affected by the tensions over Ukraine’s Crimean Peninsula.  This landing, of Soyuz TMA-10M carrying Russians Oleg Kotov and Sergey Ryazanskiy and NASA’s Mike Hopkins, could help prove that point.  Landing is scheduled for 11:24 pm EDT (9:24 am Tuesday local time at the landing site).

Fortuitously, noted Russian space authority Anatoly Zak will be speaking at the National Air and Space Museum (NASM) earlier that day as part of the NASM/Applied Physics Lab Space Policy & History Forum series.  Zak runs the RussianSpaceWeb.com website and is author of the superb book Russia in Space published last year.  His talk is at 4:00 pm ET.   There is no charge, but RSVPs are REQUIRED in order to enter the part of the museum where the talk will be held.  See the entry for Monday below for instructions.

Lots of other interesting hearings, meetings and conferences are on tap.   Here’s what we know about as of early Sunday afternoon.

Crimea Situation Not Affecting U.S.-Russian Space Relationship So Far

Crimea Situation Not Affecting U.S.-Russian Space Relationship So Far

Russia’s actions in Ukraine’s Crimea peninsula may have chilled geopolitical relationships, but so far there is no apparent impact on space activities.

U.S. dependence on Russia for crew transportation to and from the International Space Station (ISS) as well as ISS “lifeboat” services is well known in the space community (if not by the general public).   Less well known is that two U.S. launch vehicles – Atlas V and Antares – rely on Russian rocket engines.  United Launch Alliance’s Atlas V is used primarily for national security satellites, but also some NASA and commercial spacecraft and two of NASA’s commercial crew competitors plan to use it.  Orbital Sciences Corporation’s Antares is used to launch cargo to the ISS.

NASA Administrator Charlie Bolden was asked about any impacts on ISS operations yesterday in connection with the release of the FY2015 budget request.  He stressed that everything is “normal” with regard to ISS operations.   The ISS crew currently consists of three Russians, two Americans and one Japanese.  Two of the Russians and one American are due to return to Earth in a few days (March 10 EDT) and a new crew – also two Russians and an American – will launch at the end of the month.

A number of international crises have occurred during the past 13 years of ISS operations, Bolden said yesterday, citing the 2008 conflict between Russia and Georgia, another former USSR republic, as an example.  “People in [the ISS] program are focused on how to make the world better,” Bolden insisted, and indicated there has been no impact on the ISS program because of current tensions.

The United States has been dependent on Russia for taking crews to and from the ISS since the space shuttle program was terminated in 2011.   NASA’s commercial crew program is designed to facilitate the development of new U.S. crew space transportation systems by the private sector, but none is expected to be operational before 2017.   The ISS has been dependent on the Russians for lifeboats to escape the ISS in an emergency since the beginning of the program. Some of the commercial crew vehicles might be able to replace that capability.  Under current schedules, however, there is no way to keep crews aboard the ISS without Russia until at least 2017.   (Russia also needs the United States to keep the ISS operating, since the U.S. segment provides electrical power, for example, to the Russian segment.)

Michael Gass, President and CEO of United Launch Alliance, reassured Congress at a hearing this morning that launches of the Atlas V rocket also will not be affected.  Gass and competitor Elon Musk, CEO and Chief Designer of SpaceX, appeared before the Senate Appropriations Committee’s Defense Subcommittee (SAC-D) today to discuss DOD’s procurement of launch services.  SpaceX is trying to break into the DOD market, which is dominated by ULA with its Delta IV and Atlas V rockets that are used to launch virtually all U.S. national security space satellites (as well as a few NASA and commercial missions).

The Atlas V’s RD-180 engines are Russian.  Subcommittee chairman Dick Durbin’s (D-IL) first question was directed at Gass on this topic    Noting that there is talk of sanctions, Durbin asked Gass for his assessment of the reliability of the supply of engines under these circumstances.  Gass replied that ULA has a two-year stockpile of engines and the blueprints for making more themselves if needed.   He added that ULA has produced specific parts from those blueprints to demonstrate that they can, if needed, build that exact engine.   He also noted that the Delta IV could be used.

“We are not at any risk” for supporting the nation’s launch needs, Gass insisted, adding that  “We have always kept our ability” to not be “leveraged in case of any kind of supply interruption.”

Musk, conversely, used ULA’s reliance on Russian and other foreign parts as a rationale for arguing that the Atlas V be discontinued.   He agreed with U.S. space policy, which requires two families of launch vehicles to meet national needs, but said they should be ULA’s Delta and his Falcon.  Musk may have been sincere, but some might view his proposal as disingenuous since his two competitors for NASA’s commercial crew program – Boeing and Sierra Nevada – both plan to use Atlas V to launch their spacecraft (CST-100 and Dream Chaser, respectively).  If it were phased out, that would leave SpaceX as the only option.

Orbital Sciences Corporation’s Antares rocket also uses Russian engines – NK-33’s, which are refurbished by Aerojet Rocketdyne and redesignated AJ-26.  Antares is currently used only for launching cargo missions to the ISS under NASA’s Commercial Resupply Services (CRS) contract, although the company is seeking additional customers.  Each Antares uses two NK-33/AJ-26 engines.  Press reports indicate Aerojet acquired 36 of them, so there apparently is a substantial inventory, but Space News recently reported that Orbital is looking at two or three alternatives – all Russian – for future supplies.   A spokesman for Orbital said the company was “watching the situation carefully” and the number of engines is sufficient to meet its entire CRS contract with NASA.  The first stage core of the Antares is made in Ukraine and he said there are three in the United States right now which will take the company through early to mid 2015.  Two more are scheduled for delivery in the second half of this year and “so far, so good” with their suppliers in Ukraine.

Note:  This story was updated with the information from Orbital’s spokesman.
