Satellite Celebrates 20 Years Working in Orbit 199

Posted by michael from the retirement-age dept.
lloydwood writes "The UoSAT-2/UO-11 small satellite was launched into low Earth orbit on 1 March 1984 from Vandenberg Air Force Base. Twenty years later, it's still in orbit and operational -- and we recently found launch footage. To celebrate the twentieth anniversary of starting in orbit, the original video celebrating the UoSAT-2 launch is available (in windows media and mpeg). Thrill to the computers, the clothes, and the haircuts of 1984. SSTL has launched more than twenty satellites since."

    The Oscar 7 [amsat.org] satellite was launched from the same place in 1974. It spent about 20 years dead in space after its batteries shorted, before it started working again out of the blue.

    Incidentally, that launch pad [spaceflightnow.com] is about 3 miles from where I'm sitting. I can see it if I climb up on the antenna tower on the roof, but management got mad last time I did that to watch a launch.

    Things like this should be publicized much more than the stupid mistakes NASA makes. It's hard to keep a car running 20 years even with a constant supply of oil and maintanence work. This is much cooler, and deserves more media attention than a mixing up of metric and Imperial measurements (all though the mixups are STILL important). Eh, just a quick rant.

      Actually, this would be more akin to keeping a computer running for 20 years non-stop, without ever having to manually powercycle it, and without replacing a single piece of hardware, in the middle of antarctica. Much more impressive that just doing good car maintenance.

      Still, I think it's pretty sad that computers are even more frail than we humans are. For ages most of what we built outlasted us; now the tables have turned.

    Thrill to the computers, the clothes, and the haircuts of 1984.

    Although we can be reasonably well-assured that the computers were state-of-the-art at the time, the clothes and haircuts are another matter. Please remember that these are professional geeks we're talking about, and are therefore not exactly cutting edge when it comes to fashion. To all appearances it was closer to 1978 than 1984.

    I know this because I was in college in 1984, and we all looked great, but these guys look like dorks.

    • Although we can be reasonably well-assured that the computers were state-of-the-art at the time

      Actually, the one computer that I thought I recognized in the video was an Apple II. That would have hardly been "state-of-the-art" by 1984, though probably it was appropriate technology (i.e. rugged, cheap, well-understood).

    Considering that batteries die with age, solar panels degrade with exposure, and radiation of all sorts bombard the spacecraft. Also you have to have fuel to station keep, and it is only recently that ion thrusters have become available that dont require a lot of reaction mass to operate.

    20 years of operation in the harsh environment of space gets my applause.
    • From a linked page: Jan King, W3GEY reports AO-7 is almost certainly running only off the solar panels. It is very likely to be on only when in the sun and off in eclipse. Therefore, AO-7 will reset each orbit and may not turn on each time.

      The batteries have probably gone, but the fact that the rest of it is still operating is amazing.

      I notice it has a CCD camera but I've been unable to find any pictures. Does anyone know if it is operational?

    UoSAT-2 was not a Nasa mission. It was built by Surrey Satellite Technology Ltd in Guildford, a University town just west of London. We [sstl.co.uk]'ve grown quite a bit since then. We specialize in building small satellites (think 100 kgs, not 1000's of kgs). It's a different way of doing things to the way NASA and ESA usually does, but it's catching on.

      They are fairly large birds, large enough that pieces of them may reach the surface, so they much prefer to deorbit them under control than wait for them to fail and reenter wherever they will.

    AMSAT-UK is issuing 1000 special edition QSL cards to radio amateurs world-wide that submit signal/reception reports from the satellite during the month of March. Super-special edition QSL cards are given to radio amateurs who submit signal reports on March 1 (today), the satellite's anniversay.

    For the non-ham-operators among us, a QSL card (not SQL) is basically a post-card that hams send each other after making contact.

    So earlier today, remembering that I had read about the March 1st QSL cards, I pulled up my handy sat prediction software (PREDICT) along with the equally handy gsat client, updated keplerian elements, synced my pc's time so I could achieve the most accurate predictions possible.

    Had a good pass of UO-11 with about 50 degrees at elevation at 3:45 this afternoon (20:45 UTC) ... went out to the jeep and hooked my quad-band Yaesu VX-7R into a 5/8th wave magmount antenna (2-meter band) hoping to get the best possible reception I could with my gear. Adjusted for frequency doppler, and BAM! There it was... I had UO-11's telemetry on 145.825 ... got nice and loud during mid-pass ... record a WAV file of the telemetry when the signal was at it's best. When the sat was exiting my half of north america, I was still faintly hearing the telemetry on 145.820, adjusted down for doppler.

    So, of course, I submitted my signal report to AMSAT-UK this afternoon. They're going to verify my data, and I get a gold star when they're done. Today, I reached a new pinnacle of geekdom. Long live the hams!
