Dragon launchpad abort test a success

The competition heats up: SpaceX’s first abort test of its Dragon capsule was completed successfully this morning.

The test not only demonstrated the capsule’s ability to escape the launchpad and land safely in the ocean nearby, it proved that its SuperDraco thrusters have the power to lift the spacecraft off the pad, which also means they have the power to lower the capsule to a soft landing on land.

Five things to know about the Dragon launchpad abort test

The competition heats up: In anticipation of its Wednesday, May 6, launchpad abort test of its Dragon capsule, SpaceX has put out a press release providing an overview of the test and what will happen.

The launch window opens at 7 am (Eastern), but don’t be surprised if it doesn’t happen then. They have a very long launch window, and could do it almost anytime during the day.

Indecision at Virgin Galactic over engine design

In the heat of competition: Sources at Virgin Galactic suggest that the company has still not made up its mind on the type of engine it will use on SpaceShipTwo.

Messier sums up the situation perfectly:

The lack of clarity about SpaceShipTwoโ€™s main propulsion system is highly unusual. Itโ€™s difficult if not impossible to think of another space project that was uncertain about its primary propulsion system after nearly a decade of development.

Increasingly I do not see this spaceship ever flying, which saddens me. They had a ten year head start over everyone else, and have squandered it.

An update on Sarah Brightman’s astronaut training

The competition heats up: New detailed photos of Sarah Brightman’s training for her September tourist trip to ISS have been released.

The photos appear to dispel the rumors that Brightman might be replaced with her backup tourist for the flight to ISS.

Some might consider this flight nothing more than a publicity stunt. While it surely is that, for Brightman it also is a dream come true. And the publicity will not simply be good for her career, it will do wonders to sell the idea of space tourism and space exploration.

In fact, there is never really any downside to freedom and allowing people to follow their dreams, and this tourist flight to ISS will prove it.

Furniture for space!

Students at Rice University have built a chair and table expressly designed for use in a low gravity environment like the Moon or Mars.

The students interviewed astronauts to get an idea of what was needed, and did the design under NASA supervision. Their design is clever in that it can be packed easily, but I still wonder about the weight of transport. I don’t see the first explorers to Mars being able to afford bringing their furniture with them. I expect they will instead figure out ways to improvise chairs and tables from the materials on hand.

New Shepard makes its first test flight

New Shepard launch

The competition heats up: Blue Origin completed on Wednesday its first test flight of its reusable suborbital spacecraft, New Shepard.

After reaching an altitude of 307,000 feet, or 58 miles, the capsule successfully separated from its first stage, what they call the propulsion module, and safely parachuted back to Earth. The first stage, designed to also be recoverable, was not recovered successfully. According to Jeff Bezos’s explanation, they “lost pressure in our hydraulic system” and that they were trying to land it vertically, like SpaceX’s Falcon 9 first stage.

The cropped image on the right of the full resolution image, gives us a close-up of the capsule and propulsion module. The small fins on the propulsion module suggest the capability for a vertical landing, but it is unclear from the image whether the module has legs, though other images and videos strongly suggest there are legs on this module.

The flight itself, getting above 50 miles, reached space according to most definitions. In fact, Blue Origin with this flight has accomplished what Virgin Galactic has been promising to do for more than a decade, a suborbital test flight of its spacecraft. Blue Origin’s flight was unmanned, but it demonstrated that their design works. They will of course have to re-fly the capsule as well as land that first stage successfully to prove the design’s re-usability, but this flight shows that they are off to a very good start. And their webpage clearly shows that they are almost ready to start selling tickets for suborbital flights.

The most significant success of this launch, however, is the performance of the BE-3 rocket engine. Blue Origin has convinced ULA to hire it to build the engines for its new Vulcan rocket. This success justifies that decision.

I have embedded their videos of the full flight below the fold.

Progress freighter declared lost

The Russians have declared lost the Progress freighter that had been launched to ISS yesterday.

They never could regain control of the craft, plus it was in an incorrect orbit. Moreover, the U.S. Air Force has detected debris nearby, suggesting a significant failure of some kind.

The Russians are now considering delaying the next manned launch, scheduled for May 26, while they investigate this failure. Both Soyuz and Progress use some of the same systems, including the radar system that failed on Progress, and they want to make sure the problem won’t pop up on the manned mission.

At the same time, they are also considering advancing the launch date of the next Progress to ISS from August 6.

Based on these reports, I think they might swap the launch dates for the two flights. A Dragon is scheduled to go to ISS in between these missions, though that schedule could be changed as well to accommodate the Russian plans.

Progress freighter in big trouble

A Progress freighter launched by Russia to ISS on Tuesday was placed in the wrong orbit, has not deployed its radar antennas needed for rendezvous, and is not responding properly to commands on the ground.

Whether it is in the wrong orbit might be an incorrect report, but other sources demonstrate clearly that the spacecraft is tumbling out of control. Based on all these reports, it does not look good for this vehicle. The crew on ISS, including the two astronauts on a year-long mission there, might have to do without these supplies.

Meanwhile Russia is proceeding with its plans to consolidate control of all aspects of its aerospace industry under the banner of a single government “super-corporation” run by Roscosmos. Considering the number of technical failures they have had with spacecraft and rockets in the past five years, it seems to me that this is the worst approach for solving these problems. Then again, Russian culture strongly favors a top-down authoritarian approach, so it might work better under this Soviet-style approach.

I don’t believe it, but we are going to find out in the coming decades.
