Russians delay next Angara launch to replace Briz upper stage

11:24 am

The competition heats up? The Russians have delayed until late 2016 the first test flight of the heavy-lift version of their new Angara rocket so that they can fly it with its own new upper stage, rather than using the trouble-plagued Briz upper stage used on Proton.

In other words, they want to dump all the components of the Proton as soon as possible. Whether this will solve the quality control problems that seem to be systemic to their aerospace industry however remains questionable. If I was a commercial satellite company I would have as little faith in Angara, until it has proven itself through a number of launches.

Rogozin pins Proton failure on “moral degeneration”

2:31 pm

In a speech before the State Duma, Russian deputy prime minister Dmitry Rogozin blamed the “moral degeneration” of the top leaders of their county’s aerospace industry for Saturday’s Proton launch failure.

“With such degeneration in the leadership of the enterprises, there’s no surprise at such a high degree of accidents,” said Rogozin who said that “space bosses have long gone into their own space.” … The vice premier expressed those that the force of “legal gravitation will lead them [those responsible for the failure of the Progress and the Proton] to where they should be,” RIA Novosti quoted him as saying.

In other words, expect more arrests and prosecutions. Meanwhile, there is little evidence that Rogozin or Putin are doing anything to make their space industry more competitive and thus capable of generating the profits necessary to keep it afloat.

Update on Saturday’s Proton launch failure

10:15 am

Link here. The failure was in the third stage, which was the cause of a previous Proton failure last May.

Note that the Proton also put a commercial satellite in the wrong orbit in October when the upper stage underperformed.

Overall, the Russians are doing a very poor job in eliminating the serious quality control problems that have plagued their aerospace industry in recent years. If anything, the problems appear to be worsening.

Sarah Brightman pulls out of her flight to ISS later this year

9:08 am

Citing family issues, Sarah Brightman has suddenly canceled her plans to fly to ISS later this year as a space tourist.

All the press announcements of this decision emphasize that she was doing quite well in the training program, but one wonders. There had been rumors of being replaced in recent weeks, and the “family issues” cited in today’s announcement could be a cover for anything.

Either way, this is unfortunate, because her flight would have been quite entertaining and would have done a great deal to promote the space tourism industry.

What caused the failed separation of the Soyuz and Progress?

8:59 am

A good translation of this week’s press release from the investigation into the April 28 Progress failure indicates that the failure occurred because of an abnormal separation of the freighter from the upper stage.

After reviewing all the materials, members of the State Commission came to a preliminary conclusion that a version of the abnormal separation had been objectively confirmed, which includes two subsequent events related to the depressurization (disintegration after the cutoff of the third-stage engine) first of the oxidizer tank and then of the fuel tank, Roskosmos said.

In other words, the separation was so abnormal it put both the freighter and the upper stages in the wrong orbits, with the Progress tumbling and damaged, and with the upper stage almost immediately disintegrating.

They are now studying the data to try to figure out what caused the bad separation so they can inspect other Soyuz upper stages for the same problem and fix them before launch.

Russians confirm flip of Progress and Soyuz launches

4:54 pm

It’s official: The launch of the next crew to ISS will be delayed until late July to allow both a Progress freighter to launch first as well as give investigators more time to figure out what went wrong with the Soyuz upper stage during last month’s Progress launch.

In addition, the crew that had been slated to return to Earth this week will remain on board for another month to reduce the amount of time the station is manned with only 3 astronauts.

It appears that investigation is zeroing in on the upper stage of the Soyuz rocket, whose tanks apparently depressurized prematurely, causing the freighter to separate early and end up in an incorrect orbit.

Russian sources confirm their plan to flip launches to ISS

8:31 am

Though not yet officially decided, managers in the Russian space agency are definitely considering switching the launch dates of the next Soyuz and Progress missions to ISS, so that the unmanned cargo flight flies first.

Both spacecraft use the Soyuz rocket, and it now appears that the cause of last week’s Progress failure was a problem in the Soyuz third stage. They want to check out all Soyuz third stages before they put any humans on one. Switching the flights gives them time to do it. It also gets needed cargo to ISS sooner.

Progress failure causes delay in next manned mission to ISS

5:22 pm

Russian sources suggest that they will postpone the next manned mission to ISS from May 26 to June 11 as they investigate the failure of the Progress freighter last week.

This article also suggests that the Russians might flip the next Progress and Soyuz flights to have the Progress go first. (This schedule change is something I suggested might happen last week, right after the launch failure.)

Progress freighter declared lost

9:16 am

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.
