Second Try's A Charm for SpaceX and NASA

Second Try's A Charm for SpaceX and NASA

The second try was the charm for SpaceX.   Launch of Falcon 9 was successful this time at 3:44 am Eastern Daylight Time (EDT).  The first attempt on May 19 was aborted less than one second before liftoff.   This time, the SpaceX Dragon capsule reached orbit and its solar arrays unfurled right on schedule.

The goal is for Dragon to berth with the International Space Station (ISS).  It is full of supplies for the 6-person ISS crew. The next four days are full of various test maneuvers as Dragon proves that it can safely operate in the vicinity of the ISS.   If all goes well, the ISS crew will grapple Dragon with Canada’s robotic arm and pull it into a docking port.   Eighteen days later, Dragon will unberth the same way, reenter, and land in the Pacfic Ocean off the U.S. west coast.

A lot is riding on the success of this mission.  NASA is paying part of the costs for developing the Falcon 9 and Dragon, as well as Orbital Sciences Corp.’s Antares rocket and Cygnus spacecraft — which have not launched yet — as part of its Commercial Orbital Transportation Services (COTS) program, also known as “commercial cargo.”  NASA plans to buy cargo-to-ISS services from both companies now that NASA itself has no way to send cargo or crews to the ISS.  Without the space shuttle, which was terminated last year, NASA has been relying on other partners in the ISS program to provide cargo and crew transportation services.   Russia, Europe and Japan have cargo delivery systems.  Only Russia can launch crews to the ISS and bring them home.

NASA also is paying for SpaceX and three other companies to develop “commercial crew” space transportation systems to take crews to and from ISS.  Such services are not expected to be ready for several years yet, however.

SpaceX Launch Still on for 3:44 am ET Tomorrow

SpaceX Launch Still on for 3:44 am ET Tomorrow

The second attempt by SpaceX to launch its Dragon spacecraft to the International Space Station is on track as of this hour for launch at 3:44 am Eastern Daylight Time (EDT) tomorrow.

The launch was aborted less than one second before launch on Saturday because of a faulty check valve on engine 5.  SpaceX and NASA are hoping for better luck this time.

Engine Chamber Pressure Problem Scrubs SpaceX Launch, Next Try Probably May 22

Engine Chamber Pressure Problem Scrubs SpaceX Launch, Next Try Probably May 22

The launch of SpaceX’s Dragon spacecraft on the Falcon 9 rocket was scrubbed at the very last moment today because of a high engine chamber pressure reading in engine 5.  SpaceX President Gwynne Shotwell confirmed that preliminary diagnosis at a 6:30 am Eastern Daylight Time (EDT) post-scrub press briefing today.

A launch abort is always better than a launch failure, and not particularly uncommon especially with new rockets.   Aborting right at the moment of launch is unusual and made this one more of a nail-biter than most.  The launch was aborted at T-0.5 seconds — half a second before liftoff.   Shotwell said all nine engines ignited properly, but engine 5 immediately began “trending high” and exceeded the abort limit.

The vehicle is being safed and Shotwell said that technicians would be able to go out to the pad about noon today to determine what went wrong.   Until more is known, a new launch date cannot be set, but the next opportunity is May 22 at 3:44 am EDT.   The company and NASA are also looking at the next day, May 23, at 3:22 am EDT, but they do not know if the range is available that day. 

Shotwell said that if the engine needs to be replaced, it wil take only a “couple of days.”   SpaceX has another Falcon 9 already at Cape Canaveral and the engines could be swapped expeditiously even though that would mean bringing the rocket back to the hangar.   She said they could roll back to the hangar and return to the pad by May 22. 

The launch abort was not a failure, she stressed.  “We aborted with purpose.  It would have been a failure if we lifted off with an engine trending” in the wrong direction.

The launch is a demonstration flight that is part of NASA’s Commercial Orbital Transportation Services (COTS) program to facilitate the emergence of commercial companies that can launch cargo to the International Space Station (ISS).  NASA is providing some, but not all, of the funding to SpaceX and to Orbital Sciences Corp. to develop cargo space transportation systems and will buy services from them once they are operational.   Orbital has not yet launched its Antares rocket and Cygnus spacecraft.

SpaceX’s first COTS test flight in December 2010 was successful, launching the Dragon spacecraft into orbit and recovering it at sea after two orbits of the Earth.   Two more SpaceX test flights were planned, but SpaceX convinced NASA to combine them into this one flight. The objectives of this flight includes berthing at the International Space Station (ISS) to deliver supplies to the ISS crew.

Events of Interest: Week of May 21-26, 2012

Events of Interest: Week of May 21-26, 2012

The following events may be of interest in the coming week.  The Senate is in session through Saturday, then will take a week off for the Memorial Day recess.  The House left for its Memorial Day recess on Friday (other than pro forma sessions) and will return on May 30. 

During the Week

The marquee event for the week will be whether SpaceX tries again to launch its Falcon 9 rocket and Dragon spacecraft to the International Space Station (ISS).  The first launch attempt today (May 19) was scrubbed with less than one second to liftoff when the engine chamber pressure on one of the Falcon’s nine engines was too high.   If the problem can be fixed in time, the next launch opportunity is May 22 at 3:44 am ET.  Another possible launch opportunity is May 23 at 3:22 am ET, but NASA and SpaceX did not know immediately if the range was available at that time.  Stay tuned for updates from SpaceX or NASA.

Separately, the Senate Armed Services Committee (SASC) will markup its version of the FY2013 National Defense Authorization Act this week.  Subcommittee markups are early in the week, with the Strategic Forces subcommittee marking up on Wednesday at 9:30 am.  Full committee markup begins later that day at 2:30 and continues the next day.  The meetings are closed to the public so are not listed below.   The House passed its version of the bill, H.R. 4310, yesterday.

Faulty Check Valve Root Cause of SpaceX Abort; Retry May 22

Faulty Check Valve Root Cause of SpaceX Abort; Retry May 22

SpaceX just announced that it has discovered the root cause of the failure this morning of its Falcon 9 rocket.  The launch was aborted at 4:55 am ET with less than one second to go before liftoff.

A faulty check valve was to blame, according to a press release emailed by the company about 6:00 pm ET:   “During rigorous inspections of the engine, SpaceX engineers discovered a faulty check valve on the Merlin engine.  We are now in the process of replacing the failed valve.  Those repairs should be complete tonight.  We will continue to review data on Sunday.  If things look good, we will be ready to attempt to launch on Tuesday, May 22nd at 3:44 AM Eastern.”

Earlier today, SpaceX and NASA said another opportunity exists on May 23 at 3:22 am ET, although they did not immediately know if the range is available that day.

Stay tuned for more updates from SpaceX and NASA.

 

SpaceX Aborts Launch of Dragon Spacecraft At Last Moment – update 2

SpaceX Aborts Launch of Dragon Spacecraft At Last Moment – update 2

UPDATE 2:  Post-scrub launch briefing will be at 6:30 am EDT.  Watch on NASA TV.  Follow us on Twitter @spcplcyonline.

UPDATED with identification of problem and next launch opportunity

The launch of SpaceX’s Dragon spacecraft aboard a Falcon 9 rocket at 4:55 am Eastern Daylight Time (EDT) this morning was aborted at the last moment. 

Countdown was proceeding on schedule and at T-0 everyone was expecting the vehicle to lift off.  But it did not. 

SpaceX said the problem was a high chamber pressure reading in engine 5.  The computer automatically shut down the launch.

The nominal scrub turnaround is three days and the next launch opportunity will be Tuesday morning at 3:44 am EDT.

 

SpaceX on Track for 4:55 am EDT Launch Tomorrow

SpaceX on Track for 4:55 am EDT Launch Tomorrow

SpaceX’s launch of the Falcon 9 rocket and Dragon spacecraft is “go” for launch at 4:55 am Eastern Daylight Time (EDT) tomorrow from Cape Canaveral, FL.  NASA reports there is a 70 percent chance that the weather will be acceptable at launch time.

SpaceX will provide coverage beginning at 4:15 am.   NASA‘s coverage starts earlier, at 3:30 am.    (Follow us on Twitter @spcplcyonline.)

A lot is riding on the success of this mission, though NASA and SpaceX officials have tried to dampen expectations, reminding everyone that this is a test flight and tests sometimes go awry.  The flight is part of NASA’s Commercial Orbital Transportation Services (COTS) program to facilitate the emergence of a “commercial cargo” capability where companies develop systems to take cargo to the ISS on a commercial basis rather than NASA developing the systems itself.  NASA is providing some, but not all, of the funding for SpaceX and Orbital Sciences Corp. to develop commercial cargo systems and will buy services from them.  With the termination of the space shuttle program last year, NASA does not have its own ability to send cargo (or crews) to the ISS anymore.   Cargo can be sent only on Russian, European or Japanese spacecraft.   Only Russia can launch crews to the ISS.

Tomorrow’s launch is the second COTS test flight for SpaceX.  The first, in December 2010, successfully lofted a Dragon spacecraft into orbit and it safely reentered, landing in the ocean.  SpaceX planned three demonstration flights, but convinced NASA to combine the second and third, so if this mission achieves all of its objectives, SpaceX could begin offering services to NASA soon.  Orbital Sciences has not yet launched its Antares rocket or Cygnus spacecraft, but NASA hopes that service also will be available in the next year.   SpaceX has a head start on Orbital because Orbital replaced another company (Rocketplane Kistler) that failed early in the COTS program.

The first step for tomorrow’s mission is getting the Dragon spacecraft into orbit.   Assuming the Falcon 9 rocket performs that task successfully, the next step is berthing Dragon with the International Space Station (ISS) on Day 4 of the mission.   If that is successful, Dragon will remain at the ISS for about two weeks and then reenter and land in the Pacific Ocean off the west coast of the United States.  A press kit with a detailed timeline is on the SpaceX website.

No living people are aboard, but ABC News reports that a canister with the ashes of 308 people, including James Doohan who played Scotty on the original Star Trek series, will rocket into space on the second stage of the Falcon 9.   A company named Celestis sells the opportunity to send people’s ashes into space and reportedly has a performance guarantee that if a launch fails, they will relaunch ashes that have been held in reserve for just such an eventuality.   Of the 308 remains that will be aboard this flight, 208 are reflights from a failed SpaceX launch in 2008 (of its Falcon 1 rocket), including those of NASA astronaut Gordon Cooper.

As noted, the canister containing the ashes is on the second stage of the Falcon 9, not in the Dragon capsule.   Dragon is loaded with supplies for the ISS crew.   Three new crewmembers just arrived at the ISS on Wednesday, joining three others who have been aboard for several months.   Dragon will maneuver itself close to the ISS and the ISS crew will use Canada’s robotic arm to grapple it and pull it into a docking port.

In the future, SpaceX hopes to use Dragon to launch people into space, but that step is several years away.  NASA is funding SpaceX and three other companies to develop “commercial crew” space transportation systems with the hope that at least two will be operating in the 2016-2017 time frame. 

President Threatens to Veto House DOD Authorization Bill, Space Code of Conduct in Dispute

President Threatens to Veto House DOD Authorization Bill, Space Code of Conduct in Dispute

The White House said yesterday that it would veto the FY2013 National Defense Authorization Act (NDAA) if it passed Congress in its current form.  The House will begin debate on the bill, H.R. 4310, today.

The White House veto threat was just one shot fired in the escalating debate over the nation’s economic future as the election season ramps up.  Though not an economic issue, one of the provisions to which the White House objects would prohibit the Administration from agreeing to an International Code of Conduct for space activities without the advice and consent of the Senate or unless it is authorized in law.

The NDAA authorizes funding and provides policy guidance for the Department of Defense (DOD) and related activities.   In last year’s Budget Control Act (BCA), Republicans and Democrats on Capitol Hill and the White House agreed to drastic cuts in federal spending in return for congressional approval to raise the debt ceiling.   The House, however, has reneged on that deal.  It passed a bill last week exempting DOD from the spending cuts and imposing those cuts on other parts of the budget, particularly food stamps and other entitlement programs.

In its Statement of Administration Policy (SAP) on the bill, the White House says it will veto the final version of the bill “if the cumulative effects of the bill impede the ability of the Administration to execute the new defense strategy and to properly direct scarce resources” or if it contains language that would “impinge on the President’s ability to implement the new START Treaty and to set U.S. nuclear weapons policy.”

The SAP has a lengthy list of other provisions to which the White House objects.  One is opposition to Section 913, which would prohibit the President from agreeing to an International Code of Conduct for space activities without the advice and consent of the Senate or unless it is authorized by law.   Under the Constitution, treaties are subject to the advice and consent of the Senate, but the Administration argues that the space Code of Conduct would be a voluntary agreement with no enforcement provisions, not a treaty, and thus not subject to congressional action.   The extent to which the White House would consult with Congress before agreeing to a space Code of Conduct has been a sticking point since the concept emerged.

The European Union (EU) drafted a Code of Conduct for Outer Space Activities in 2008 and released a revised draft in October 2010.   In January 2012, Secretary of State Hillary Clinton announced that the United States would work with the EU and other countries on finalizing a version of the agreement after bringing more countries into the discussion, a process expected to take several years.  A major theme of the agreement is space sustainability — ensuring that the space environment remains usable in the future  — by defining responsible behavior so those who behave irresponsibly can be singled out.    A Chinese antisatellite (ASAT) test in 2007 and the accidental collision of an American commercial Iridium communications satellite and a defunct Russian Kosmos satellite in 2009 created thousands of pieces of space debris in the most heavily used part of low Earth orbit.  Those events prompted calls for limiting the creation of space debris and enhancing space situational awareness so countries and companies operating in space know the current and projected locations of satellites and debris so collisions can be avoided.

Some members of Congress, however, are concerned that the Code of Conduct is a back-door approach to arms control in space that could limit U.S. options.  They do not want the Administration agreeing to anything without their approval.   In the SAP, however, the Obama Administration said that Sec. 913 of the NDAA “encroaches on the Executive’s exclusive authority to conduct foreign relations and could severely hamper U.S. ability to conduct bilateral space cooperation actitivies with key allies.”

While important enough to make the list of Administration objections to the House version of H.R. 4310, the Code of Conduct is likely to be a minor issue compared to the funding disputes.   The sharp differences between Republicans and Democrats over how to reduce the federal deficit were once again brought into sharp relief yesterday as House Speaker John Boehner vowed not to approve another increase in the debt limit without deep spending cuts that nonetheless protect the defense budget.  Republicans continue to insist on not increasing taxes and, in fact, say that they will extend the Bush-era tax cuts that will expire at the end of this year.  Democrats want to reduce the decifit by a combination of spending cuts and tax increases and the President insists that he will not approve an extension to the Bush-era tax cuts for wealthier individuals.

The expiration of those tax cuts, and harsh spending reductions to defense and non-defense discretionary spending under the sequestration provisions of the Budget Control Act that automatically take effect on January 1, 2013 unless Congress changes the law, are driving the political and fiscal debate in Washington.  Sequestration could have dramatic consequences for the aerospace industry according to the Aerospace Industries Association (AIA).  It is leading the drive to raise awareness of what could happen to the U.S. aerospace industry if Congress and the White House do not agree on a different course of action.

House to Debate Change to Export Rules for Commercial Satellites

House to Debate Change to Export Rules for Commercial Satellites

The House will continue debate today on the FY2013 National Defense Authorization Act (NDAA), H.R. 4310, turning its attention from general debate to a long list of amendments.

One of those many amendments (click on “amendments” tab) could change the export control environment for commercial satellites.  Amendment 152, offered by Representatives Adam Smith (D-WA), Howard “Buck” McKeon (R-CA and chairman of the House Armed Services Committee), Dana Rohrabacher (R-CA), and Kevin McCarthy (R-CA and House Majority Whip) would authorize the President to remove commercial satellites and related components from the U.S. Munitions List (USML).  The Administration would have to submit various determinations and reports, and exports to certain countries are prohibited, but in essence the amendment would restore to the President the authority to make the decision on whether commercial satellites are governed by the USML or the Commerce Department’s Commerce Control List (CCL).   Congress took away that authority in the FY1999 National Defense Authorization Act in the wake of the “Loral-Hughes” controversy where Congress found that those companies had assisted China in developing missile capabilities by helping them determine why several Chinese launches of U.S.-built communications satellites failed.  

China is on the list of countries to which exports of commercial satellites still would be prohibited.  The others are Cuba, Iran, North Korea, Sudan, Syria, and “any other country with respect to which the United States would deny the application for licenses and other approvals for exports and imports under section 126.1 of the International Traffic in Arms Regulations” or ITAR.

The amendment comes in the wake of a long-awaited report from the Departments of State and Defense — the “section 1248 report” — on the national security implications of moving commercial satellites and their components from the USML to the CCL.  The U.S. commercial communications satellite industry has been arguing stridently for more than a decade to ease export controls for their products arguing that European competitors are benefitting by making “ITAR-free” satellites that are not subject to U.S. export control regulations.
