    I did! Love launches. I think we need cameras in LEO so we can see the whole shebang.

    That was one of the coolest things EVER. Hopefully all goes well.. I'll be trying to catch mission updates through the afternoon!

    Woot! Emily Lakdawalla retweets that spacecraft separation went well... awaiting additional burns to send the spacecraft on their way!

    You got a link for her twitter feed? The spacelightnow one is a bit slow.

    I asked him for it. She's pretty well known.

    It isn't really a "blind link". PraedSt asked for a link to Emily Lakdawalla's (of the Planetary Society Blog and such) twitter feed. I obliged. Read back a few posts.

    PraedSt,

    Emily was getting tweets from someone translating a Russian feed of the launch, but yeah, I understand what you mean. We get spoiled with the full-on video play-by-play to LEO by US launches I think.

    Very bad...

    A very serious problem has been reported... Apparently the first on-orbit burn didn't occur as planned

    I just saw this, Zvezdichko.... :-( very sad indeed. Is there still hope they might make contact with it in some sort of safe mode?

    Grrr..

    Yes, there are hopes that the spacecraft can be reprogrammed for another burn on the next day... It can stay up there for several days... But the team has to act quickly

    Anatoly Zak reports censorship after launch:

    Russian space agency, Roskosmos, limited its "coverage" of the mission's initial phase by two sentences about the successful launch, however provided no updates on the status of orbital maneuvers in time for critical engine burns. During the entire night of November 8 and early morning of November 9, a web site of NPO Lavochkin, the spacecraft's prime developer, featured "news" about the preparation of the mission and awards to the company's workers! The official Russian media, which avalanched the Internet with headlines about the successful launch, were also eerily silent about the post-liftoff status of the mission. Thus, Russia's first 21st century planetary mission was circling Earth in the state of a virtual informational blackout.

    Bad news:

    From various translated sources, it appears the probe is now in a parking orbit. What should have happened is that two and a half hours after launch, the first burn should have put the spacecraft into an higher orbit around Earth, and a second burn should have occurred 126 minutes later, which would have sent it the spacecraft to Mars. Neither occurred, and it is yet to be determined if the problem was with the flight computer or flight hardware.

    “It is a complex trajectory, and the on-board computers could have simply failed to send a “switch on” command to the engine,” Popovkin said, adding that it is an emergency situation, which has been anticipated and could be corrected.

    “We will attempt to reboot the program. The spacecraft is currently on a support orbit, the fuel tanks have not been jettisoned, and the fuel has not been spent,” he said.

    "It seems it couldn't reorient itself away from the Sun towards the stars so the sidewall closed. It was foreseen by the flight program. Now, we have found its location, and we have to unpack the sidewall, to check the telemetry and after that we will restart the spacecraft control program to reboot the mission. The craft is in a support orbit. The fuel tanks were not jettisoned after the first switch-on." [Vladimir Popovkin]

    Here's to still hoping! Maybe they can hayabusa the thing!

    P.S. Apologies to Gillian for "verbing" a spacecraft ;-)

    I'm hoping with you. However, I don't agree with your verbing of Hayabusa. After all, they already Apollo 13'ed Hayabusa.

    The question of course is: why couldn't it turn away from the sun in the first place? I think that will determine whether or not the craft can still continue its mission.
    With sufficient thrust, water towers fly just fine.

    I suppose in a general sense, you're right about "Apollo 13ing," but I can claim hayabusaing for unmanned craft? ;-)

    Some sources have mentioned the need to figure this out in 3 days, and I think the implication was battery life (since the craft may not have had the proper orientation to charge the batteries). How long do they have before they have to get going due to trajectory changes needed en route to Mars?

    Two weeks was the last figure I saw: I'll have to google it again to be sure.

    EDIT: Wikipedia says 2 weeks.

    It'd be damn shame if this mission fails. It represented a new start for Russia as it was the first Mars probe designed completely in the post Soviet era.

    Seems odd. They're had such good luck with landings on Venus.

    Vesti.ru, Russianspaceweb.com and an astronomy forum in Russian language report that the next attempt to fire the engine of the probe is in 21:16 Moscow time TODAY...

    We are full of good news. It seems that there is enough power so they can delay the interplanetary trajectory injection for weeks, not three days as it was reported before...

    GO, PHOBOS-GRUNT!

    Thats great news, what is it with the Soviet/Russian bad luck with regards Mars?

    I'm hoping for success. That's one expensive probe, with a promise to tell us important things if it works.
