SpaceX Founder and Chief Designer Elon Musk said at a CRS-3 post-launch press conference today that the Dragon spacecraft had a problem with its Draco thrusters, but everything appears OK now. Meanwhile, he is waiting for more data from the test of landing legs on the Falcon 9 first stage that took place over the ocean. A heavy sea state dampened hopes that the stage itself would be recovered.
Speaking about two hours after the successful launch of this third SpaceX operational cargo mission to the International Space Station (ISS), Musk expressed happiness that the launch went as planned and did not seem worried about the thruster problem. He said that an isolation valve that leads to the thruster pods did not respond so a backup valve was used instead. Dragon has 18 Draco thrusters that are used to maneuver the spacecraft from its initial orbit to the ISS. They are distributed across four pods: two pods hold four thrusters and two hold five thrusters. An anomaly with the Draco thrusters caused a problem during the CRS-2 mission last year. Musk was asked if today's problem was related to last year's and he said it was too early to tell.
As for the test of landing legs on the Falcon 9 first stage, Musk said he had seen data from the rocket stage's descent down to Mach 1.1 and it looked good. SpaceX planned to get data via aircraft and ship observations, but high seas prevented the ship from getting close to the stage as it reached the water. Musk was not optimistic that the stage could be recovered and brought back for inspection because of the rough seas. The data telemetered to the aircraft from the rocket stage, however, showed that it had a zero roll rate, which Musk considered a success in and of itself. He remains hopeful that a stage can be recovered sometime this year and reflown next year. He wants to make the Falcon 9 reusable. Eventually the rocket stages would descend and return to a landing pad rather than being recovered at sea.
This launch was delayed several times for various reasons and the chances of launch today were low because of poor weather. SpaceX's competitor for NASA commercial cargo launches, Orbital Sciences Corp., has been working toward a May 6 launch of its Cygnus spacecraft on its second operational cargo mission to the ISS, dubbed Orb-2. NASA indicated several days ago that if SpaceX CRS-3 launched today, it would delay Orb-2 until June 9. NASA Associate Administrator for Human Exploration and Operations Bill Gerstenmaier said today that he would ask Orbital to continue planning for a May 6 launch until Dragon is successfully berthed to ISS on Sunday. If that goes as planned, he will release the Orbital team and reschedule the launch for June.
Gerstenmaier said that NASA was planning to have a P-3 aircraft observe the descent of the Falcon 9 first stage today, too, but icing conditions prevented the aircraft from flying. NASA wants data on the first stage's supersonic thruster firings during descent because it is applicable to Mars entry-descent-and-landing.
SpaceX's Hans Koenigsmann, Vice President for Mission Assurance, said that the company will attempt another landing leg test over the ocean on the next flight. He also confirmed that the first flight of SpaceX's Falcon Heavy rocket will take place from Kennedy Space Center, FL next year rather than from Vandenberg Air Force Base (VAFB), CA. SpaceX President Gwynne Shotwell made the comment on Monday as she signed an agreement with NASA for a 20-year lease of Launch Complex 39A, the same Launch Complex once used for the space shuttle and Apollo flights to the Moon.
Shotwell's statement on Monday was a surprise. In 2011, the company announced it had broken ground on a new launch pad for Falcon Heavy at VAFB. SpaceX has not yet flown a Falcon Heavy, which is being designed to take 53 metric tons (117,000 pounds) to low Earth orbit. The company advertises it as "the world's most powerful rocket" that will be able to take twice as much mass into orbit as the Delta IV -- currently the largest U.S. rocket -- for one-third the cost.
Despite a gloomy forecast, the weather held for launch of SpaceX's third operational cargo mission (CRS-3) to the International Space Station this afternoon. The Falcon 9 rocket lifted off on time and its Dragon cargo spacecraft is in orbit.
The launch was delayed several times, most recently on Monday when it was scrubbed shortly before launch because of a technical problem.
A post-launch press conference is scheduled for 5:00 pm ET today that will be carried on NASA TV. There is much interest in how SpaceX's test of landing legs on the Falcon 9 first stage went; hopefully they will have news at the press conference. SpaceX eventually wants to return the first stage to land and reuse it, but today's test was over the ocean.
NASA may also announce a new launch date for the next cargo mission to the ISS. This will be the second operational launch of Orbital Sciences Corporation's Antares/Cygnus system -- Orb-2. The current launch date is May 6, but because this SpaceX launch was delayed several times, NASA said earlier that they may ask Orbital to wait until June 9 to launch that mission. Orbital launches these flights from Wallops Flight Facility, VA.
Dragon will arrive at the ISS on Sunday morning, April 20, and be grappled using Canadarm2 at about 7:14 am ET. It will be berthed to an ISS docking port around 9:30 am ET. NASA TV will cover the events live beginning at 5:45 am ET.
With the successful launch today and assuming a successful berthing on Sunday, NASA plans to conduct a spacewalk on Wednesday, April 23, to fix a broken computer on the exterior of the ISS. NASA astronauts Rick Mastracchio and Steve Swanson will begin the spacewalk at 8:55 am ET. NASA TV coverage of the spacewalk will begin at 8:00 am ET.
The NASA Advisory Council (NAC) gave NASA kudos for better articulating its plans for the future of the human space flight program, but is not convinced the program is affordable. They chose not to issue any findings or recommendations on that topic at the two-day meeting that ended yesterday and will continue their deliberations in July.
Budget realities were a prevalent theme throughout the two day meeting. Presidential Science Adviser John Holdren spoke with the Council on Wednesday and portrayed President Obama as a strong supporter of NASA “tempered only by the painful realities of these budgetary times.” “I’ve often said NASA is 20 pounds of mission in a 10 pound budget,” he added, and offered no cause for optimism that NASA’s budget situation will change anytime soon. Noting that some people have petitioned the White House to double NASA’s budget, he replied that instead “we have to double or triple what we can do ... with every dollar.”
NASA Administrator Charlie Bolden joined Holdren at the table and both spoke on a broad range of NASA issues, but the human spaceflight program was the elephant in the room. Tom Young, one of six new members of NAC, confronted the issue head on, telling the two that they were communicating that the United States has a sound human spaceflight strategy, but some think it is more of a “passion and a dream than a strategy” because strategies need adequate resources to be executed.
Bolden replied that there has never been a time when a strategy has been properly resourced and trying to develop budgets for programs that have 30 year time horizons, like sending people to Mars, is especially challenging. While acknowledging that “we don’t have what really would be a valid strategy that the common man would accept,” he stressed that NASA is “working on a plan that at least identifies the milestones to get there.”
NAC Chairman Steve Squyres asked Holdren directly about the Asteroid Redirect Mission (ARM). He wanted to know whether ARM satisfies President Obama’s 2010 directive that NASA send astronauts to an asteroid or whether the agency is expected to still do that after ARM (where the asteroid will be brought to the astronauts). Holdren replied that the President’s 2010 directive was “laid out with very broad brushstrokes” and ARM is “consistent” with it. The overall goal is to make technological and operational advances relevant to protecting Earth from asteroids as well as potentially exploiting them commercially and to establish U.S. presence near and beyond the Moon as a steppingstone to Mars. “Exactly how that gets done is still evolving,” he said. He praised ARM as an “incredibly valuable” mission because it serves so many purposes using technology already under development in the current budget.
NASA human spaceflight chief Bill Gerstenmaier next took the podium and set the context for ARM within NASA’s long term human spaceflight plan. His key message is that NASA has an incremental, step-by-step strategy to send people to Mars, but budget constraints will limit the pace of the program and committing to a specific time for when people will land on Mars should be avoided.
The first step beyond low Earth orbit is cis-lunar space (between the Earth and the Moon) and lunar orbit. That is where the Space Launch System (SLS) will send Orion on its first crewed missions beginning in 2021 whether or not an asteroid is there, he said. NASA is looking at several candidate asteroids for ARM and the 2024-2025 time frame appears more likely for when an asteroid (or a piece of one), redirected from its native orbit by a robotic probe launched probably in 2019, would arrive in lunar orbit. The key, Gerstenmaier emphasized, is to test spacecraft systems and human adaptation to spaceflight in cis-lunar space as a step towards Mars whether or not an asteroid is there. As for landing humans on Mars, he does not think that is likely by the 2030s under current budget projections.
NASA Administrator Bolden often talks about landing people on Mars in the 2030s as NASA’s goal although President Obama’s space policy calls only for putting humans into orbit around Mars by that time. Developing landing systems to get from orbit to the Martian surface will be extremely challenging and expensive as exemplified by the Mars Curiosity rover’s “Seven Minutes of Terror” landing sequence. Curiosity is much smaller than the mass needed to land humans on the planet.
Many NAC members praised Gerstenmaier’s articulation of the long term plan, but were struck by the first of his six “strategic principles” for implementing the program: “Executable with current budget with modest increases.”
Gerstenmaier explained that he cannot make progress towards these goals if his budget grows only at one percent per year as currently forecast. While he has not defined how much “modest” is, he said it would be “disingenuous” for him to say he could accomplish the plan without an increase. His message was that with a modest budget increase, progress could be made, albeit on an incremental basis and at a slower pace than many would prefer.
Wanda Austin, another of NAC’s six new members, questioned why, then, he was presenting a program he knows is not affordable since the chances of increased funding are so slim. She and two other NAC members (Charlie Kennel and Les Lyles) served on the 2009 Augustine committee that reviewed NASA’s human spaceflight program at that time and concluded NASA’s budget would have to be increased by $3 billion a year to accomplish a human spaceflight program “worthy of a great nation.”
That increase never materialized and now, five years later, it seems as though NASA is back on an unaffordable path.
Austin’s views were widely shared by other NAC members. Yesterday, the Council considered a draft finding from its Human Exploration and Operations Committee that would have endorsed NASA’s human spaceflight strategy as presented at this meeting. The Council decided it could not adopt such a finding without adding a cautionary statement that it does not reflect budgetary reality. Rather than attempting to modify it on the spot, they decided to table the finding and make this topic a major focus of their next meeting in July.
SpaceX will try again to launch its third operational cargo mission to the International Space Station (ISS) on Friday. The launch window opens at 3:25 pm ET, but the weather forecast is poor. Meanwhile, the ISS spacewalk needed to fix a broken computer on the exterior of the space station is now planned for Wednesday, April 23.
The SpaceX CRS-3 launch was scrubbed on Monday because a helium valve in the stage separation pneumatic system in the Falcon 9 first stage was not holding the correct pressure, the company said in a statement today. It added that the launch could have gone ahead and relied on a backup check valve, but "SpaceX policy is not to launch with any known anomalies."
The weather was great on Monday, but much has changed since then and the forecast for Friday is only 40 percent favorable. NASA TV will cover the launch beginning at 2:15 pm ET and SpaceX will webcast it beginning at 2:45 pm ET. If all goes as planned, the Dragon spacecraft with its load of cargo will arrive at the ISS Sunday morning, April 20, and be grappled by Canadarm2 at about 7:14 am ET. NASA TV will cover the events beginning at 5:45 am ET.
One of the more interesting aspects of this launch is that SpaceX will test landing legs for the Falcon 9 first stage as a step towards eventually making the vehicle reusable. This test will take place over the ocean so the vehicle will fall into the water, but only after SpaceX collects the data it needs to determine if the landing legs performed as expected. A SpaceX official stressed that it is an experiment and the company is only 30-40 percent confident it will work.
If the weather or anything else interferes on Friday, SpaceX plans to try again on Saturday at 3:02 pm ET.
Meanwhile, NASA continues preparations for a "contingency" spacewalk (as opposed to a regularly scheduled spacewalk) to replace a malfunctioning computer called a Multiplexer-DeMultiplexer (MDM) on the outside of the space station. NASA determined over the weekend that Dragon could be berthed to the ISS despite the malfunction; the primary MDM is working fine. The MDMs control some of the robotic systems aboard ISS. NASA astronauts Rick Mastracchio and Steve Swanson will perform the spacewalk on Wednesday, April 23, under the current plan. NASA space station program manager Mike Suffredini described this as one of the easier tasks and the spacewalk is scheduled for only 2.5 hours.
If the SpaceX launch is scrubbed on Friday, however, NASA will move the spacewalk up to Sunday, April 20.
The Government Accountability Office (GAO) gave NASA credit today for improved cost and schedule performance in its major acquisition programs. Nevertheless, it cited several programs that need continued monitoring. GAO reviews NASA's major acquisition programs every year as requested by Congress.
GAO said that the portfolio of NASA projects it reviewed "saw cost and schedule growth that remains low compared to GAO's first review." Not that every project is doing well, though.
In all, GAO reviewed 19 programs spanning robotic and human spaceflight in its 104 page report. It did not make any recommendations, but cited several programs that require continued monitoring. One is the Ice, Cloud and Land Elevation Satellite-2, ICESAT-2. GAO said the cost of the satellite's single instrument -- Advanced Topographical Laser Altimeter System (ATLAS) -- being developed by NASA's Goddard Space Flight Center will grow by at least 15 percent and the spacecraft will miss its 2017 launch date. GAO said that NASA traced the problem to immature systems engineering analysis and consequently replaced the project management team and added more expertise.
Among GAO's other top worries are the Space Launch System (SLS) and Orion programs.
Other programs that bear watching include:
GAO also provided a snapshot of the status of the three commercial crew competitors -- Boeing, Sierra Nevada and SpaceX. According to the report,
Overall, it reports that commercial crew program officials cite the following challenges: concern that the program will not be fully funded, reducing competition and thereby increasing costs of commercially available transportation capabilities; complications such as development of the system to allow the commercial vehicles to dock with the International Space Station, which could impact schedule; and "closing a risk related to Federal Aviation Administration licensing issues."
The other programs reviewed by GAO for this report are:
Presidential Science Adviser John Holdren is scheduled to discuss the Obama Administration's vision for NASA with the NASA Advisory Council (NAC) tomorrow (April 16, 2014). NASA Administrator Charlie Bolden and the head of NASA's human spaceflight program, Bill Gerstenmaier, will also address NAC. The meeting comes three weeks after a tense exchange between Bolden and House Science, Space and Technology (SS&T) Committee Chairman Lamar Smith (R-TX) over whether NAC Chairman Steve Squyres agrees with NASA's contention that the Asteroid Redirect Mission (ARM) is a step towards someday sending people to Mars.
The Obama Administration is continuing its efforts to convince Congress and the space community in general that ARM should be the next step for the U.S. human spaceflight program. It has generated little enthusiasm since it was announced almost exactly one year ago when President Obama submitted his FY2014 budget request to Congress. ARM is an iteration of President Obama's declaration almost exactly three years earlier, on April 15, 2010, that he was directing NASA to send astronauts to an asteroid as the next step in human spaceflight after he cancelled the Bush-era Constellation program to return humans to the lunar surface.
NASA is still developing the mission concept for ARM. Gerstenmaier briefed NAC's Committee on Human Exploration and Operations yesterday on competing concepts for how to carry out the mission. The two options are to try to redirect a small asteroid into a lunar orbit or to go to a larger asteroid and pluck a large sample (e.g. a boulder) from its surface and move that into lunar orbit. Once in lunar orbit, astronauts would visit it. Gerstenmaier focused on the value of using cis-lunar space (between the Earth and the Moon) and lunar orbit as a "proving ground" for human missions beyond low Earth orbit. He also stressed that although ARM has been characterized as a "one-off" mission, in fact it is part of an integrated plan to get humans to Mars.
There is little disagreement that the long term goal for the U.S. human spaceflight program -- in partnership with other countries and the commercial sector -- should be landing people on Mars (though it is not unanimous). For decades, the debate has been over whether or not returning to the lunar surface is a prerequisite. Intermediate destinations, like asteroids, were rarely discussed until a committee created by President Obama shortly after taking office in 2009 posited a "flexible path" approach as an alternative that included asteroids and Lagrange points. The committee, chaired by Norm Augustine, did not make recommendations, but laid out "Moon First," "Mars First" and "Flexible Path" options.
Holdren is Director of the White House Office of Science and Technology Policy (OSTP), which is largely blamed or credited, depending on one's point of view, for choosing Flexible Path and cancelling the Constellation program. He has testified to Congress about ARM enthusiastically, but does not appear to have won many converts. In one sign of good news for the Administration, however, the 2014 NASA Authorization Act approved by the House SS&T's Space Subcommittee last week would not prohibit spending money on ARM. That is an improvement over last year's version of the bill, which would have done so. That bill was never reported from committee.
Holdren's appearance before NAC tomorrow may be an effort to win over those members of the space community, especially NAC chairman Steve Squyres, at least, about the value of ARM as part of a plan to send people to Mars.
Squyres testified to the House Space Subcommittee last year that he does not consider ARM as necessary to achieve that goal. At another hearing three weeks ago on NASA's FY2015 budget request, full committee chairman Rep. Lamar Smith (R-TX) challenged Bolden on that point. Smith quoted Squyres as testifying that "I see no obvious connection between [ARM] and any of the technologies or capabilities that are required for Martian exploration." Smith is pushing the Mars 2021 Flyby mission as the next step in human spaceflight instead.
In a tense exchange, Smith reminded Bolden about Squyres's testimony and Bolden replied that if Squyres were asked today, he would not hold the same position. Smith retorted: "I don't doubt you could put political pressure on him." Bolden responded: "I put no pressure, I can't put pressure, on Steve Squyres." Smith insisted Squyres's testimony stands "unless you have other information." Bolden said: "I have other information, which is talking to [him] weekly. Steve Squyres counseled me 'don't make this seem like you're going to save the planet. Show us, the NASA Advisory Council, how this is relevant to getting people to Mars.' We've subsequently done that." Smith said Squyres's testimony stands until he hears differently from Squyres.
Smith continued his criticism in an April 3 press release after Bolden made comments to two National Research Council panels that Mars Flyby 2021, Smith's preference, is not a steppingstone to landing people on Mars.
As for convincing Squyres and the rest of NAC, Bolden, Holdren and Gerstenmaier will be there to make the case for ARM in person and in public tomorrow morning. The meeting is at NASA Headquarters and is available remotely via WebEx and telecom. The detailed agenda, as of today, is posted on the NAC website. Bolden is scheduled for 9:10 am ET, Holdren for 10:00 am ET, and Gerstenmaier for 11:00 am ET.
Senator Richard Shelby (R-AL), the top Republican on the Senate Appropriations Committee, told Secretary of Commerce Penny Pritzker last week that two of NOAA’s satellite programs are nice-to-have, but not essential and do not meet his priority test in today’s budget environment. The two are COSMIC-2 and SIDAR (a new program this year that replaces the Polar Free Flyer).
Shelby is the top Republican on both the full committee as well as its Commerce-Justice-Science subcommittee, which funds NOAA (as well as NASA). While his Democratic counterpart Senator Barbara Mikulski (D-MD), who chairs the full committee and the subcommittee, is known as an advocate of environmental satellites, both Senators have expressed reservations over the years about NOAA’s ability to manage satellite programs effectively.
In recent years, the disagreements have centered on NOAA’s two major satellite development programs – the Joint Polar Satellite System (JPSS) and the Geostationary Operational Environmental Satellite (GOES)-R series. Those programs appear to have stabilized, but NOAA has several other satellite programs and Shelby believes at least two of them are of lower priority than other NOAA activities. NOAA has broad-ranging duties, including fisheries and coastal zone management, of great importance to Alabama.
Pritzker testified about the full range of issues at the Department of Commerce at the April 10 hearing. The President is requesting $8.8 billion for the Department. It has a panoply of responsibilities from radio frequency spectrum management for federal government users to management of the contract for assigning domain names for the Internet to cyber-security research at the National Institute of Standards and Technology (NIST) to implementing export-import policies to preparing for and conducting the 2020 Census.
NOAA would get $5.5 billion of the $8.8 billion. NOAA’s satellite programs would get $2 billion of that.
Shelby questioned the need for COSMIC-2 and SIDAR, calling them “nice-to-have” projects rather than “must-haves” like JPSS and GOES. NOAA is requesting $6.8 million for COSMIC-2 and $15 million for SIDAR, a total of $21.8 million of its $2 billion satellite budget.
Ironically, NOAA requested no funding for COSMIC-2 last year, but this committee added $4 million. That amount was cut in half after negotiations with the House, for a total of $2 million in FY2014. For FY2015, NOAA is requesting $6.8 million. A follow-on to COSMIC, a joint project with Taiwan, it involves a constellation of satellites that uses GPS signals for radio occultation (GPS-RO, or alternatively GNSS-RO for Global Navigation Satellite System-Radio Occultation) measurements to enhance the accuracy of polar-orbiting weather satellites. Rick Anthes and Thomas Bogdan published an op-ed in the Washington Post today explaining why COSMIC-2 is a “crucial element” in enhancing weather prediction. Anthes was co-chair of the National Research Council’s 2007 decadal survey on Earth Science and Applications from Space.
SIDAR is new in the FY2015 request, replacing last year’s Polar Free Flyer (PFF), which received none of the $62 million requested. In that case, the House position to not fund PFF was adopted in negotiations with the Senate.
PFF was an effort to get into orbit three instruments that were orphaned after the National Polar-orbiting Operational Environmental Satellite System (NPOESS) was cancelled and replaced by the much smaller JPSS spacecraft. They are the Total Solar Irradiance Sensor (TSIS), Advanced Data Collection System (A-DCS), and transponders for the Search and Rescue Satellite-Aided Tracking (SARSAT) system.
With no funding provided for PFF in FY2014, NOAA created the SIDAR (Solar Irradiance-Data-Rescue) line item for FY2015. The FY2015 request is modest -- just $15 million – and the projection for the next four years is shown as TBD.
Shelby did not mention two other NOAA satellite programs – Jason-3 and DSCOVR – for which funding is also requested this year ($25.7 million and $21.1 million respectively). The request for JPSS is $916.3 million and for GOES-R is $980.8 million.
Shelby said that he was concerned that “not all of the satellite projects ... are truly necessary to the core mission of NOAA” and that NOAA has not presented a “viable gap mitigation plan” for a potential gap in data from polar-orbiting weather satellites between the time existing satellites stop working and the first JPSS is launched.
Mikulski also asked when the committee would get that plan. Pritzker said NOAA is currently focused on trying to move up the launch date for JPSS-2 so there is greater overlap with JPSS-1 (which does not answer the question of the gap between existing satellites and JPSS-1). Mikulski wanted Pritzker to assure her than Pritzker was “standing ... sentry over this” and would provide a new cost estimate for JPSS this month as promised. Pritzker said she was not sure of the timing. Mikulski also lauded Kathy Sullivan, recently confirmed as NOAA’s Administrator after serving in an acting capacity, for improving communications between NOAA and the Senate and better management of satellite programs.
Pritzker testified to the House Appropriations CJS subcommittee the previous day (April 9), but satellite issues were barely mentioned. Subcommittee chairman Rep. Frank Wolf (R-VA) did, however, take the time to praise the service of NOAA Assistant Administrator for Satellite and Information Services (NESDIS) Mary Kicza for her “yeoman” work as head of NOAA’s satellite programs for many years. Kicza had just announced plans to retire this summer. Wolf and Pritzker agreed on the need to find a successor as soon as possible.
At 3:39 pm EDT, SpaceX's launch director stated that the planned 4:58 pm launch of CRS-3, the company's third operational cargo mission to the International Space Station (ISS), was scrubbed for the day. The next launch opportunity is Friday, but the weather forecast is iffy that day.
As many people tuned in to NASA TV at 3:45 pm EDT to listen to live launch coverage, the NASA announcer said that launch had just been scrubbed and replayed the SpaceX announcement from minutes earlier. The speaker identifies himself as the LD -- launch director -- and says "We have encountered an issue that will result in our scrubbing today's 4/14 launch attempt."
SpaceX soon posted a message on its website stating that the problem is a helium leak on the Falcon 9's first stage.
NASA and SpaceX earlier had stated that if the launch did not go today, the next opportunity is Friday, but an Air Force weather officer at a pre-launch briefing yesterday said the weather was only 40 percent favorable on Friday.
SpaceX says on its website that it will fix the helium leak by then, but acknowledges the poor forecast.
The launch window on Friday, April 18, opens at 3:25 pm ET.
Here is our list of space policy-related events for the upcoming week and any insight we can offer about them. The House and Senate are on Spring Break until April 28.
During the Week
SpaceX was given the go-ahead today (Sunday) to proceed with launch of its third operational cargo mission (CRS-3) to the International Space Station (ISS) tomorrow, April 14, at 4:58 pm EDT. Failure of a computer aboard the ISS late Friday meant ISS mission managers needed to assess whether the computer -- a Multiplexer/DeMultiplexer (MDM) -- had to be replaced before the Dragon spacecraft arrives at ISS. The MDM controls some robotic operations aboard ISS that are needed to berth Dragon to an ISS docking port. Some ISS cargo spacecraft (Russia's Progress and Europe's ATV) dock with ISS using their own systems. Others (Japan's HTV, Dragon, and Orbital Sciences' Cygnus) berth with ISS. That means they position themselves close to the space station, but then the robotic Canadarm2 must reach out and grapple them and move them over to a docking port when they are "installed" onto the port. Canadarm2 is fine. The primary MDM is fine. It is only the backup MDM that is malfunctioning. NASA is planning a spacewalk to replace that unit on April 22. Assuming the launch goes as scheduled, Dragon will arrive at the ISS Wednesday morning around 7:00 am EDT.
One interesting aspect of this launch is unrelated to the ISS cargo mission. SpaceX wants to make the Falcon 9 rocket reusable. This launch will test landing legs on the Falcon 9's first stage. After its work is done of getting the second stage and Dragon on their way, the first stage will come back down vertically and deploy the four 25-foot long landing legs. The rocket stage will be over the ocean, not land, and will fall over into the water, but not before SpaceX collects the data it needs. A SpaceX official said the company gives the experiment only a 30-40 percent chance of success, but someday Falcon 9 first stages could return to a landing pad for reuse.
Apart from the SpaceX events, a number of NASA Advisory Council meetings are on tap this week, along with a Marshall Institute panel discussion on the scientific, technical and legal aspects of "Human Settlement in Space: Bases in Near Space." That's on Thursday. On Saturday, the irrepressible Mike Gold of Bigelow Aerospace has organized an out-of-the-box panel discussion at an unusual (for the space crowd) venue -- the Awesome Con event at the Washington Convention Center. Awesome Con is a three-day "celebration of popular culture" and Gold's panel will discuss "From Dreams to Reality: How Science Fiction Has Served as an Inspiration for Lifelong Careers and Activities in Space Exploration." He's got a great group of folks on the panel: himself, former astronaut Pam Melroy, Tim Hughes from SpaceX and Peter Marquez from Planetary Resources. (Peter formerly worked for Orbital Sciences and before that was best known as "the space guy" at the White House National Security Council who gets the credit, along with Damon Wells, then with OSTP, for getting President Obama's 2010 National Space Policy completed and released just 17 months after the President took office.) Sounds like fun!
The rescheduled GEOINT 2013 conference also is taking place in Tampa, FL, Monday-Thursday. The conference was originally scheduled for early October 2013, but suffered from Congress's decision to shut the government down for two weeks. No government employees could go to the conference as either speakers or attendees, so it had to be rescheduled (we can only imagine how much that must have cost -- ouch). Anyway, it looks like an amazing program with Director of National Intelligence James Clapper, Director of the National-Geospatial Intelligence Agency Letitia Long, Director of the Defense Intelligence Agency Lt. Gen. Michael Flynn, and Director of the National Reconnaissance Office Betty Sapp among the impressive lineup of speakers.
Here's the list of what we know about as of Sunday afternoon.

NASA International Space Station (ISS) Program Manager Mike Suffredini said the agency will go ahead with the launch of SpaceX's CRS-3 cargo mission tomorrow, April 14, despite a malfunctioning computer aboard ISS. A spacewalk is now planned for April 22 to repair that unit.
The launch of a Dragon spacecraft aboard a Falcon 9 rocket is scheduled for 4:58 pm ET Monday and the weather is 80 percent favorable for the launch. If anything should delay it, the next opportunity will be on Friday, April 18, when the weather outlook is worse.
Suffredini declared at a noon press conference that the launch is "good to go" after mission managers concluded that appropriate positioning of the ISS solar arrays would protect ISS operations in case of another MDM failure. MDM is a Multiplexer/Demuliplexer - a computer that controls some of the robotic functions aboard the ISS. The primary MDM is working fine; it is the backup that is not responding to commands. Suffredini said they did not know why and will replace it with a new unit during a spacewalk now planned for April 22.
Among the cargo being taken to the ISS is a new spacesuit and replacement parts for the spacesuits already on board. A clogged filter in one of the onboard spacesuits imperiled European astronaut Luca Parmitano during a spacewalk last summer when his helmet filled with water from the spacesuit's cooling system. NASA ultimately traced the problem to silica contamination from filters in the spacesuit that are designed to clean and scrub the water loops. New filters are included in the spacesuit components being taken to ISS aboard Dragon.
SpaceX Vice President of Mission Assurance Hans Koenigsmann said at the same press conference that SpaceX is only 30-40 percent confident that its test of landing legs for the Falcon 9 rocket's first stage will work. SpaceX is working on making the Falcon 9 reusable and is experimenting with landing legs that someday could allow the first stage to return to a landing pad. The test on this flight is not that ambitious and will take place over the ocean. Stressing that it is experimental, Koenigsmann said that the first stage will descend vertically and deploy the four 25-foot high legs over the water before eventually falling over into the water. The first stage is heavily instrumented and cameras aboard a recovery ship will try to take video. He said the test happens quickly and will be over by the time the rocket's second stage reaches orbit.
When asked for NASA's reaction to SpaceX's reusability test, Suffredini said NASA supports commercial space and is happy to help as long as the primary mission is not affected. NASA determined this test would not impact Dragon's mission to ISS.
