Today’s launch of Dragon to ISS has been scrubbed due to “a helium leak in Falcon 9’s first stage.”
SpaceX also says they will be ready to launch by April 18, their next launch window.
The backup computer that helps operate ISS’s robot arms is not responding to commands.
The timing could not be worse.. Though the number one computer is functioning fine, this unit is essential for controlling the robot arm that will berth Dragon to ISS this week.
Side note: The article above described this problem in its headlines as a “glitch.” I despise this word, as it is generally used by government bureaucrats to minimize the seriousness of a failure. The Soviet era bureaucrats in Russia loved it. I have noticed it popping up in American news reports relating to space more and more, and it is never a very accurate description of the situation. This computer failure is not a “glitch,” it is a serious failure of an essential piece of hardware.
Update: Because a spacewalk will be required to fix the backup computer, NASA has okayed the launch of Dragon. They need it to arrive first because it carries a new spacesuit and other parts needed to replace the suit that almost drowned an astronaut during a spacewalk last summer.
Note: I was in the back country of Arizona this past weekend, caving, which is why I am only now getting up to speed on this weekend’s news.
Some real news about SpaceShipTwo: Scaled Composites has posted the logs for several successful engine test results on its webpage.
The information is sparse, but it suggests that these tests are attempts to run the engine through a full simulated flight.
The competition heats up: Houston yesterday signed a letter of intent with Sierra Nevada to provide the company a home at that city’s proposed spaceport.
The competition here is not from the spaceship company but from the spaceport. Houston is in a race with Colorado and Florida for the launch business. In fact, it appears that a lot of American cities are scrambling to attract the new aerospace launch companies, suggesting that they all see a new industry aborning and want their share.
Another example: The California legislature has passed a ten year tax exemption for spaceflight companies.
An update on China’s lunar rover Yutu.
This is an excellent summary of the mission and its status, including detailed maps outlining the rover’s path before it finally lost the ability to move.

India’s Mangalyaan Mars orbiter is now halfway to Mars.
India, unlike Israel, wants to conquer the stars, so the success of their first interplanetary mission means a lot to them.
The competition heats up: XCOR today took delivery of the cockpit assembly of its Lynx suborbital space plane.
They have said they will begin flight tests later this summer, followed by tourist suborbital flights at some point thereafter.
A Russian Progress freighter successfully docked with ISS on Wednesday, rendezvousing with the station using the fast track approach of six hours.
Congress and NASA administrator Charles Bolden battled over ISS, Russia, crew transport, and commercial space yesterday in a hearing before Congress.
Not surprising. Congress wants to know what NASA will do if Russia pulls out of ISS and Bolden really has few options if they do. He in turn was trying to get Congress to focus on funding commercial space so that we can launch our own astronauts to ISS and not depend on the Russians. A true confederacy of dunces. More here.
According to the deputy head of Russia’s space agency, they are not planning any retaliatory sanctions against NASA.
Whew! That’s a relief.
Seriously, I never expected them to do anything, as the sanctions NASA has imposed, excluding ISS, are so minor that they mean nothing to Russia. The only people NASA really hopes will react to these sanctions are Congressmen and Senators when they realize how dependent we are on the Russians to get to space.
Curiosity catches a mysterious flash of light on the Martian horizon.
Be assured, despite what some reports are suggesting, it isn’t an alien flashing a mirror at us. The top theory now is that Curiosity caught a reflection off a “glinty” rock.
Triumph of his will: Elon Musk’s effort to build a rocket company.
The article is long, providing incredible background details on Elon Musk’s life and how he got to be the world’s most famous rocket company president. Definitely worth a read.

The competition heats up: Boeing is about to begin environmental tests on a new composite fuel tank for rockets.
Tanks made of composite materials have been a dream of space engineers for decades. Lockheed Martin tried to build them for the X-33, and their failure was essentially what killed that spacecraft. If Boeing is successful here and the composite tanks can then be put into a variety of launch rockets, the savings in weight will lower the cost of getting payloads to orbit significantly.
As the NASA lunar probe LADEE nears its planned end — where it will crash onto the Moon — the scientists running it admit that they have as yet been unable to solve its primary scientific question about levitating lunar dust.
A major goal of the mission was to understand a bizarre glow on the Moon’s horizon, spotted by Apollo astronauts just before sunrise. “So far we haven’t come up with an explanation for that,” project scientist Rick Elphic, of NASA’s Ames Research Center in Moffett Field, California, said at a media briefing on 3 April. One leading idea is that the Sun’s ultraviolet rays cause lunar dust particles to become electrically charged. That dust then lofts upwards, forming a cloud that caught the light and the astronauts’ eyes.
LADEE carries an instrument that measures the impact of individual dust particles, as well as the collective signal from smaller particles. Lunar scientists had expected a certain amount of tiny dust to explain what the Apollo astronauts saw. But LADEE didn’t find it. “We did measure a signal that indicates that the amount of lofted dust has to be at least two orders of magnitude below the expectations that were based on the Apollo reports,” says Mihály Horányi, the instrument’s principal investigator, who is at the University of Colorado. Perhaps the dust lofting happens only occasionally, he suggests, and the astronauts were in just the right place at the right time to see it.
This remains an important question. Knowing what caused that horizon glow and knowing how often it occurs is essential knowledge for any future lunar base or research station.
The launches at Kennedy, delayed because of a fire at an Air Force radar facility, have now been rescheduled.
This includes a military launch by an Atlas 5 rocket on April 10 and SpaceX’s next Falcon 9 launch to supply ISS. The Falcon 9 flight will also include an attempt to bring the first stage back to a soft vertical landing over water.
The competition heats up: Even as India successfully launched its second homemade GPS satellite today, the head of of the Vikram Sarabhai Space Centre in India announced that it will launch a test flight of a manned capsule in June using that country’s powerful GSLV rocket.
In hearings today, Pentagon officials said that they are considering building American-built engines to use on our rockets rather than buy Russian-made engines.
They could do this very cheaply if they simply allowed SpaceX to bid on all military launches.
