Phobos in trouble

The Phobos-Grunt («Фобос-Грунт») probe was launched on 8/11 at 20:16 GMT and it made it into Earth orbit … but the thrusters that were to send it onto a Mars trajectory failed to fire for as yet-unknown reasons – either due to a software or hardware malfunction – so it is currently stuck in orbit. There are 2 weeks to find a solution, then the launch window closes. If it is a hardware failure the mission is over; if it is software-related the technicians might be able to radio up corrective commands. The mission failure will be a dismal blow to the Russian unmanned space program, of which this is the first probe to be sent up in over 15 years; there likely won’t be another as Russia does not have the will or funding for such programs that the USSR era did.

Progress success

Progress M-13M/45 launched on 30/10 and docked to the Pirs module of the ISS on 2/11 with no anomalies, a great relief to everyone! The crew will get some iPads (lucky them!). (NASASpaceflight.com: “Progress successfully docks to ISS; stage set for return of manned Soyuz flight”.) The next crew to launch in November will be ISS-29/30.

The Mars-500 experiment ends this week, 4 November! The crew seem to have survived with their sanity intact :-).

China’s launch of the Tiangong 1 space station module on 29/9 was successful. On 31/10 Shenzhou 8 was launched, an unmanned version of the capsule, and remotely docked to Tiangong on 2/11.

The Phobos-Grunt probe is set to launch next week, 8 or 9 November, if there are no delays – the launch window is from 5-25 November, otherwise there are another 2 years or so until the next Mars launch opportunity. It has what appears to be an official website.

I decided not to buy the Spaceflight issues mentioned last entry as they were speculative only, and the magazine too expensive.

Heavenly bodies

The cause of the Soyuz rocket crash last month was given as being due to a clogged fuel line leading to a gas generator, thought to be human error rather than a design flaw. (NASASpaceflight.com articles: 31/8, 15/9.) Crew launches on the Soyuz rocket have been delayed a little, and the next Progress launch (Progress M-13M/45P) is set for 30 October. Crew launches are on the Soyuz-FG, which has a modifed fuel injection system on the engines of the first and second stages, but it and the Soyuz-U have the same 11S510-PVB Blok-I third stage.

China is to launch the first module of its planned space station next week on a Long-March Ⅱ-F carrier rocket (MSNBC/Spacedaily articles). The module is called Tiangong 1, or “Heavenly Palace”. The module is to be used to practice rendezvous and docking, initially with the unmanned Shenzhou-8 that will be subsequently launched. If it is successful, it will be followed by Tiangong 2 and 3 space labs in a few years.

New Scientist magazine had an article about the support operations for the Mars-500 mission in its 17 September issue. (Text online here.)

The July and August issues of BIS Spaceflight magazine have a 2-part article on death in space. I am debating whether to buy the issues as the magazine is now quite expensive in Australia ($17) and hard to find. On browsing through the July issue in a newsagent, the first part was more speculation about various medical issues that might occur during a long spaceflight. A bit disappointing as I was hoping for an actual list of procedures from NASA, or whoever! The somewhat morbid topic has interested me for years, but there are no actual documents online, only occasional speculations on forums. I actually wrote out my own version of such a document in the style of other online ISS documents as part of a somewhat irreverent short story I did some years ago (“Houston, we have a corpse”) that included a space autopsy (“2001: a space autopsy” – I had some fun making up those headings :-):

Progress launch failure

For the first time after 135 launches, a Progress cargo ship failed to reach orbit on the 136th launch (since January 1978). Progress M-12M (44P) launched on 24/8, but the third/Blok 1 rocket stage of its Soyuz-U rocket failed 5m 25s into flight, achieving only a sub-orbital trajectory, and both crashed in the Choysk district of ​​the Altai Republic (South Siberia).

This comes the week after the telecommunications satellite “Express-AM4” failed to reach orbit on 17/8 after the Briz-M upper stage of the Proton-M rocket lost power after its fourth burn (NASASpaceflight.com report). Both are manufactured by Khrunichev. The damage for this, including launch costs, exceeds 20 billion rubles.

Khrunichev also manufacture the RD-0110 (11D55) liquid-propellant rocket engine used on the 3rd stage of the Soyuz rockets

The loss of the cargo is a setback but is not yet critical for the ISS crew, who have enough supplies to last until the next Progress launch on 28/10 (STS-135 also brought up a lot of supplies). However the next crew launch in September will be delayed until the cause for the malfunction is found, as they go up on a Soyuz-FG. The ISS also needs Progress ships for its periodic reboostings.

The Soyuz era

Half-way through the year and only 3 entries here! My former enthusiasm has really slackened off.

The final flight of the Space Shuttle program, STS-135 Atlantis, landed safely on 21/7 after a mission to the ISS. There has been 30 years of Shuttle missions (¾ of my life). Now Russia will be the sole means of transport to the space station until the U.S. develops its next generation of transport, either by NASA or commercial companies. Exactly what this may be seems uncertain (I have not been following the heated forum debates much) – the current NASA version seems to be the Space Launch System. I am dubious as to whether commercial companies can develop spaceflight quickly as this is a difficult and expensive endeavour.

Russians: ‘It’s our space age now’ ”, Cosmic Log, 23/7. A translation of a Roskosmos article about the Shuttle retirement is causing some ire (see NASA Watch entry) because the tone of the article appears gloating. It’s unfortunate if that is the case, though one commenter points out: “you have to be aware that russian is a harsh language, so a literal translation may come across as saying one thing, but in reality, they are saying something with a far different tone.”

The Mars-500 crew are still enroute home. They have been in “flight” 415 days, and only have around 4 months to go! (The experiment finishes sometime in November; there is no set date yet.) That period of time has gone swiftly for me, as years seem to do now; I wonder if their perception of time is similar.

The Russian Space Agency Roskosmos got a new head or chief on 29 April: Vladimir Popovkin, formerly the  First Deputy Minister of Defense, replacing Anatolii Perminov.
