The competition heats up: A Proton rocket successfully launched a Russian military satellite today.
This is Proton’s the third successful launch in a row since July’s spectacular launch crash. It seems they have straightened out their quality control problems, for the moment.
Virgin Galactic has signed a deal with NBC to televise the first commercial flight of SpaceShipTwo.
I note that with this announcement Virgin Galactic has backed off from its previous schedule for launching this flight this year. They now say it will happen in 2014.
A Texas-based company has printed the first 3D-printed metal pistol, a 45 caliber Model 1911.
Video below the fold. The gun clearly functions, though I noticed that in the video they never loaded more three rounds in a magazine, and that the gun seems to cycle weakly. I suspect that they had some feeding problems when they tried to fire a full loaded five round magazine.
Nonetheless, this achievement further illustrates that 3D printing is about to become a major method of manufacture.

Successfully growing crops in the desert using salt water and solar power.
The heart of the SFP concept is a specially designed greenhouse. At one end, salt water is trickled over a gridlike curtain so that the prevailing wind blows the resulting cool, moist air over the plants inside. This cooling effect allowed the Qatar facility to grow three crops per year, even in the scorching summer. At the other end of the greenhouse is a network of pipes with cold seawater running through them. Some of the moisture in the air condenses on the pipes and is collected, providing a source of fresh water.
One of the surprising side effects of such a seawater greenhouse, seen during early experiments, is that cool moist air leaking out of it encourages other plants to grow spontaneously outside. The Qatar plant took advantage of that effect to grow crops around the greenhouse, including barley and salad rocket (arugula), as well as useful desert plants. The pilot plant accentuated this exterior cooling with more “evaporative hedges” that reduced air temperatures by up to 10°C. “It was surprising how little encouragement the external crops needed,” says SFP chief Joakim Hauge.
The technology development here is wonderful, but it is unclear from the article whether these crops would be competitive on the open market with ordinary farm crops. The cost for this operation is not outlined.
The competition heats up? Beyonce might beat Lada Gaga into space.
And in related news, TV actor Ashton Kutcher had some serious stomach issues during a zero-G practice flight on the vomit comet.
Engineers successfully completed Mangalyaan’s second engine burn yesterday, raising its orbit to just under 25,000 miles.
Each one of these burns demonstrates the reliability of the spacecraft.
The competition heats up? According to People magazine, Lady Gaga will take a Virgin Galactic suborbital flight in 2015 and thus beat Sarah Brightman into space.
At the same time announcing that a third powered test flight of SpaceShipTwo will occur in about a month, Virgin Galactic has now admitted that commercial flights will not occur in 2013.
The competition heats up: India successfully launched its first probe to Mars today.
The mission, also known in India as Mangalyaan (which means “Mars-craft”), has at the moment only reached Earth orbit. To get to Mars, it must still complete an additional engine firing on November 30.
India has begun the countdown for the November 5 launch of its first Mars orbiter.
Just today, spacetoday.com lists fourteen different stories in the Indian press about this mission, all enthusiastic, thus indicating the excitement in that country over space exploration and this mission in particular. Nor is this event unusual. I’ve noted before how space happy India is. They not only want to catch up and pass their neighbor China, they want to catch up with the United States and Russia. Should be fun to watch.
In preparation for November 5 launch of India’s first mission to Mars, ISRO successfully performed a full dress rehearsal countdown yesterday.
We all cross our fingers and wish India well on this mission.
The article also had this additional tidbit that reveals a great deal about world culture:

Bras in space: How a bra company made the spacesuits the astronauts wore on the Moon.
Fascinating interview, though I find it humorous how it is considered absurd and unlikely for a private company that makes bras to make these spacesuits. In truth, when the Apollo missions happened, Americans had no doubt that ordinary private businesses were the best places to go to get something novel and creative done.
The complete failure of the fuel tank appears to be the cause of the massive leak that caused the launch postponement of India’s first home-made geosynchronous powered rocket in August.
Mr. Radhakrishnan [head of India’s space agency] said while the expert committee had attributed the fuel leak to stress corrosion cracking of the tank filled with propellants, exactly why this happened was “a research problem” that remains to be investigated. The next GSLV mission will switch to a better aluminium alloy material for its propellant tanks.
Up to now the reports have been somewhat vague about the cause of what was clearly an extensive leak. This story tells us that the tank essentially failed. As they filled it with propellants, cracks apparently showed up everywhere, with fuel spewing out in all directions. As far as I can remember, I don’t think there has ever been a rocket tank failure quite this spectacular.
This suggests there were fundamental design flaws in the tank or very serious quality control problems in its manufacture. With the next launch attempt scheduled for December 15, I hope India has identified the source of this incredibly basic problem and taken action to prevent it from happening again.
Update: Reader Patrick Ritchie found this older article which suggests the failed tank was an old tank of a design that was “prone for delayed cracks”. The error here then was in using this substandard old equipment rather than a newer tank.
Sierra Nevada reveals that its Dream Chaser engineering test vehicle survived its bad landing this weekend in reasonably good shape.
After lining up on the runway, the spacecraft’s nose landing skid and right main landing gear deployed normally about 200 feet off the ground. But the left main gear hung up for some reason. Sirangelo said the software issued the proper commands, leading engineers to suspect a mechanical problem of some sort.
The landing gear in the test vehicle were taken from an F-5 training jet and will not be used on operational versions of the Dream Chaser.
In any case, the Dream Chaser’s flight software responded to the unbalanced load at touchdown, keeping the spacecraft’s left wing off the ground as long as possible. But it eventually came down and the craft skidded off the runway in a cloud of dust. [emphasis mine]
They should release the video. If the vehicle’s software was able to keep the vehicle stable, even as it was speeding down a runway short one wheel, this would impress people. Not releasing video of this only feeds the doubts people have.
Sierra Nevada today released a video of the test flight this past weekend of its Dream Chaser engineering test vehicle.
Don’t get too excited. They very cleverly have edited the tape so that we do not see what happened after touchdown. You can see how the left landing gear does not completely deploy, but then they cut away. Nonetheless, the video is posted below the fold.

Sierra Nevada provides an update on the condition of its Dream Chaser test vehicle after this weekend’s glide flight and bad landing.
SNC has not yet decided whether to repair the Dream Chaser test craft, which does not use the same landing gear the orbital vehicle would use. Investigating what went wrong will take “a couple of weeks,” Sirangelo estimated. He said the vehicle, which is now in a hangar in Mojave, Calif., was “fully intact” after the crash.
“The pressure vessel was completely pristine, the computers are still working, there was no damage to the crew cabin or flight systems,” Sirangelo said. “I went inside it myself and it was perfectly fine. There was some damage from skidding.
“We learned everything we wanted to on this test, and learned more than we expected to learn,” Sirangelo said. “We believe we’ve got most of the data we need [but] I can’t honestly say, I just don’t know yet. It’s not going to affect our schedule in the long term [but] It might affect whether we do another free flight test this year or next year. We’re still assessing that.”
The company also claims that the flight met the requirements of a $15 million NASA milestone payment, since the goals of the flight were to test the vehicle’s flight capabilities, not its landing gear. (The failed landing gear used will not be the gear used on the final flight vehicle.)
They have scheduled a press conference for tomorrow. Stay tuned.
A government official today unwittingly revealed a fundamental and unpleasant truth about how governments: operate. In an interview today, the head of India’s space agency denied that his country is in a space race with anyone.
Mr. Radhakrishnan, Secretary in the Department of Space and Chairman of Space Commission, said each country — whether it’s India, the US, Russia or China — had their own priorities.
“There is no race with anybody. If you look at anybody, they have their own direction. So, I don’t find a place for race with somebody. But I would say we are always on race with ourselves to excel in areas that we have chalked out for ourselves,” he told PTI here in an interview.
How typical. By denying the reality of the competition that India is part of Mr. Radhakrishnan illustrates for me and everyone once again the basic reason all government efforts eventually fail.

In its first free flying glide test, the Dream Chaser engineering test vehicle had a perfect flight and approach to landing but flipped over on the runway when its left land gear failed to deploy.
I haven’t yet found any post landing images, nor any information about damage to the test vehicle. This is the kind of tragic failure that sometimes kills a project. The vehicle, operating unmanned, performed quite well actually, flying freely and gliding to the runway as planned. The failure of the one landing gear to deploy is a relatively easy engineering fix. However, the failure could cost a fortune, money the company might not have, if it requires the construction of an entire new test vehicle.
New quality control problems that have popped up in Russia might delay its next module to ISS by more than a year.
The company building the new module is the same one that builds the Proton rocket that has had serious problems in the last few years.
The competition heats up: Russian owned International Launch Services (ILS) today successfully used its Proton rocket to launch a commercial satellite.
This is the second successfully Proton launch since July’s spectacular failure. The company seems to be recovering, which of course means that the competition for launch services will get hotter in 2014.
Which is excellent news. The competition will keep these companies on their toes, and force them to innovate in order to stay in business. In the long run this will lower the cost to orbit and make space more accessible to everyone.
