India has begun the countdown for the November 5 launch of its first Mars orbiter.

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.

Bras in space: How a bra company made the spacesuits the astronauts wore on the Moon.

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.

Sierra Nevada reveals that its Dream Chaser engineering test vehicle survived its bad landing in weekend in reasonably good shape.

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.

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 โ€œa couple of weeks,โ€ Sirangelo estimated. He said the vehicle, which is now in a hangar in Mojave, Calif., was โ€œfully intactโ€ after the crash.

โ€œThe pressure vessel was completely pristine, the computers are still working, there was no damage to the crew cabin or flight systems,โ€ Sirangelo said. โ€œI went inside it myself and it was perfectly fine. There was some damage from skidding.

โ€œWe learned everything we wanted to on this test, and learned more than we expected to learn,โ€ Sirangelo said. โ€œWe believe weโ€™ve got most of the data we need [but] I canโ€™t honestly say, I just donโ€™t know yet. Itโ€™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. Weโ€™re still assessing that.โ€

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.

Why governments can’t do it

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 โ€” whether itโ€™s India, the US, Russia or China โ€” had their own priorities.

โ€œThere is no race with anybody. If you look at anybody, they have their own direction. So, I donโ€™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,โ€ 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.

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.

Russian owned International Launch Services today successfully used its Proton rocket to launch a commercial satellite.

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.
