SuitSat Not Looking Good So Far

Hulboy writes "According to the SuitSat website, things aren't going well for the makeshift satellite in it's first few hours. 'Reports of nothing heard from Israel, Turkey, South Africa, and two negative reports from Japan as well as the weak report below. JH3XCU reports signal only heard in SSB mode, TX cycle and doppler detectable, but no modulation... this is not looking good.'

      This wasn't the most scientific mission possible, but instead something people thought would be fun. It was kicked out the door of the ISS, basically, which means the trajectory wasn't exactly guaranteed. There was no way to ensure that it wasn't going to get hit by orbital debris -- a paint fleck on one extremity would have at least sent it spinning and significantly altered its course -- or even that it would be in something resembling a stable orbit, even for a few days.

      a paint fleck on one extremity would have at least sent it spinning and significantly altered its course

      Low earth orbit velocity is 7800m/s. The most likely, and worst way, to get hit by a paint fleck is to get hit by one in the same orbit but in the opposite direction, which would be a delta vee of 2*7800m/s.

      Let's be really generous and say a paint fleck weighs 1g and hits the suitsat (say 100kg) dead on. By conservation of momentum, the suit's velocity will decrease from 7800m/s to... 7799.844 m/s.

      In other words, it'll still be at 99.998% of it's original velocity. I won't bother calculating how little the fleck could have affected the spin, because it's not like the suit was spin stabilized to begin with. Spin fade was expected to begin with. The only significance of the fleck is that it would cause the suit to (slowly) depressurize, but more importantly possible trash the equipment if it was in the way.

      My guess is that since the equipment wasn't really designed for this kind of orbital abuse: the nasty temperature shift between night and day just caused caused some circuitry to fail from thermal expansion. Or perhaps the suit leaked; the equipment wasn't designed to work in a hard vacuum.

    The SuitSat is not a problem ... really. It's in an unstable LEO, probably tumbling all over the place, impacting all sort of other small debris. If anything, it'll clean a little bit of the crap out of its way as it comes down and burns up.

    Now, if you want to talk about dangerous space junk, where you want to look is up in the higher orbits, the so-called "nuclear safe" ones. The Soviets had a series of spy satellites that (because they didn't want to have big solar panels on them in such low orbits) had nuclear reactors. Not RTGs, honest to god liquid-metal cooled nuclear reactors. They had a system to eject the reactor cores into high orbits before the satellites re-entered (which sometimes didn't work -- one of them contaminated quite a bit of Northern Canada). But even when the systems did work, the result was a rather largish chunk of very radioactive material in high orbit.

    I'm sure there is probably a lot of other dangerous junk floating around out there, too. If you want to talk about space debris, it's out in the higher orbits that you really need to look. Especially because those are the places where you'd probably want to assemble a large space station (or park big, expensive satellites with large solar collectors), and that stuff doesn't like getting hit by old crap.

    SuitSat Status 4 Feb 2005
    ---For Immediate Release---

    Silver Spring, Maryland
    4 February 2006 at 22:00 UTC

    Paraphrasing Mark Twain....the demise of SuitSat-1 is high exaggerated!!

    It is now nearly 24 hours since the successful deployment of the SuitSat-1
    experiment. These past 24 hours have been a wild ride of
    emotions...tremendous highs...deep lows when people reported no signals and
    said SuitSat-1 was dead and now....some optimism.

    It is absolutely clear that SuitSat-1 is alive. It was successfully turned
    on by the ISS crew prior to deploy and the timing, micro-controller
    functions and audio appear to be operating nominally. The prime issue
    appears to be an extremely weak signal.

    I have heard several recordings and have monitored two passes today. When
    the signal is above the noise level, you can clearly hear partials of the
    student voices, the station ID and the SSTV signal. One of the
    complicating factors in reception is the very deep fades that occur due to
    the spin of SuitSat.

    Based on the information we know thus far, one can narrow down the issue to
    the antenna, the feedline, the transmitter output power and/or any of the
    connections in between. Through your help, we would like to narrow down
    the issue further and also gather some internal telemetry from the
    Suit. If the transmitter is running at full power, we would expect the
    Suit to end operations in the next few days to a week. If it is not, then
    it will operate much longer. Since we do not know how long this experiment
    will last, we ask for those with powerful receive stations to listen for
    Suitsat---especially during direct overhead passes when the Suit is closest
    to your area. If you can record these passes and send the audio to us, it
    would be most appreciated. We will continue to be optimistic that this
    issue will right itself before the batteries are depleted. So please KEEP
    LISTENING!

    Based on what we have learned, we would like to provide the following
    guidelines to save you time and facilitate gathering information.
    1) You need as high a gain antenna as possible with mast mounted
    pre-amps. An arrow is the minimal set...it provides very brief snipets of
    the communications. HTs and scanners won't cut it.
    2) I would not waste your time on passes below 40 degrees
    elevation. SuitSat is too far from your station to receive a reliable
    signal. We have found that closest approach provides several seconds of
    SuitSat communication with 22 element yagis.
    3) The "gold" we are looking for right now is the telemetry information
    and how long the vehicle stays operational. So if you hear any of the
    telemetry, please let us know.

    We are also working to get the voice repeater set up on ISS to downlink
    SuitSat audio on 437.80 in the event that the ISS Kenwood radio can receive
    the SuitSat transmissions. The repeater may be operational as early as
    mid-day Sunday. Please do NOT transmit on 145.99, voice or packet, until
    we have confirmed that SuitSat is no longer transmitting. These
    transmissions interfere with our ability to hear SuitSat.

    While the transmission part of the SuitSat experiment has not been stellar,
    SuitSat-1 has been tremendously successful in several areas. Some of these
    successes include:

    -We have captured the imagination of students and the general public
    worldwide through this unique experiment
    -The media attention to the SuitSat project represents one of the biggest
    ever for amateur radio
    -We have had well over 2 million internet hits on www.suitsat.org today
