LADEE hits the moon.
Russia is accelerating construction of its new spaceport in Vostochny.
The competition heats up: Russia is accelerating construction of its new spaceport in Vostochny.
The schedule doesn’t appear to have been pushed up, with the first launch still set for 2015, but they are going to initiate a second shift, and will have monthly meeting with the government to monitor progress. Under the top-down Russian way of doing things, this is how they make sure their high priority projects get finished on time and successfully.

Sierra Nevada is planning additional glide tests in the fall. using its Dream Chaser engineering test vehicle.
The competition heats up: Sierra Nevada is planning additional glide tests in the fall. using its Dream Chaser engineering test vehicle.
This is the same test vehicle that crashed last October during its first glide test when one landing gear failed to deploy properly. The glide test itself was a success however, as the vehicle did a controlled unmanned glide perfectly to the runway, and the failed landing gear was one that the spacecraft will not use once completed.
Note also that these announced flight tests will occur after NASA eliminates one of the companies competing for the final crew ferrying contract to ISS. This suggests that Sierra Nevada plans to continue development of Dream Chaser, regardless of whether they get the contract or not.

The idea is brilliant. The probe, ISEE-3, has functioning instruments. It just hasn’t been operated since the 1980s. If they can get the funds to pay for the effort, they will provide scientists a space probe for pennies.

NASA has officially handed control of launchpad 39A to SpaceX, where the company intends to launch its Falcon Heavy.
NASA has officially handed control of launchpad 39A to SpaceX, where the company intends to launch its Falcon Heavy.
The agreement turns over control of Launch Complex 39A to the commercial space transportation firm, which plans to use the launch pad for the the initial flights of the Falcon Heavy, a mega-rocket featuring 27 first stage engines generating nearly 4 million pounds of thrust at liftoff.
Pad 39A was the starting point for many historic Apollo and space shuttle missions, including the Apollo 11 moon landing in 1969 and the first and last shuttle launches in 1981 and 2011.
“We’ll make great use of this pad, I promise,” said Gwynne Shotwell, president of SpaceX, in remarks to the media moments after signing the lease. “We’ve had architects and our launch site engineering [team] working for many months on the sidelines. We will launch the Falcon Heavy from here first — from this pad — early next year.” [emphasis mine]
The highlighted quote reveals a key fact. Until recently SpaceX had been claiming that it will do its first demo launch of Falcon Heavy in 2014. This quote confirms that this schedule is not happening.

The article itself is not very informative, other than noting these comments. In fact, it has some errors that suggest the writer knows very little about China’s space effort, both civilian or military.
Nonetheless, China’s president did make this statement, which tells us that it is definitely Chinese policy. Not good.

European satellite operators are pressing Arianespace to find ways to immediately reduce the cost of launching satellites on now Ariane 5 and in the future on Ariane 6.
And why are they doing this? To quote them:
“What is sure is that Europe deserves and requires a [reorganized launcher sector] ahead of 2019, the letter says. “[C]onsiderable efforts to restore competitiveness in price of the existing European launcher need to be undertaken if Europe is [to] maintain its market situation.
“In the short term, a more favorable pricing policy for the small satellites currently being targeted by SpaceX seems indispensable to keeping the Ariane launch manifest strong and well-populated.” [emphasis mine]
It seems that they take very seriously the competitive challenge being presented by SpaceX.

The backup computer that helps operate ISS’s robot arms is not responding to commands.
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.

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.

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.

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.

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.

Boeing is about to begin environmental tests on a new composite fuel tank for rockets.
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.
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.

UrtheCast has released its first image of Earth, taken from one of its cameras on ISS.
UrtheCast has released its first image of Earth, taken from one of its cameras on ISS.
The UrtheCast (pronounced Earth-Cast) system, which was installed (not without trouble) on the International Space Station at the end of 2013, is composed of two cameras. The Theia “medium resolution” camera took this shot; the full picture has a resolution of 3200×8000, or about 25 megapixels. The high-resolution device, which will capture video, is still being calibrated.
Eventually UrtheCast plans to provide free, constant, near-real-time video of the globe from far above — that is, when it’s not being rented out to parties interested in a quick satellite snap of an area. Powerful cameras able to respond quickly to such requests are in high demand by everyone from law enforcement to disaster-relief coordinators.

It might simply be the man got a promotion, but it also might be that he knows the problems SpaceShipTwo is having and sees his chances of flying there going down. His willingness to work for XCOR instead could also be looked at as a kind of endorsement of that company’s chances of success.
