Amateur Rocket to Carry Ham Radio Payload to Space

n1ywb writes "An amateur rocket team this month will attempt to send a 21-foot-tall rocket carrying a ham radio avionics package into the fringes of space. The launch by the Civilian Space Xploration Team (CSXT) could occur as early as Monday, May 17. Some 20 months ago, the last CSXT try to reach space ended some three seconds after launch when the rocket's engine exploded. Avionics Team Leader Eric Knight, KB1EHE, says CSXT has since rebounded from that devastating blow with a newer, bigger vehicle. In terms of Amateur Radio, the GoFast rocket will transmit telemetry on the 33-cm amateur band and Amateur TV at 2.4 GHz using a high-quality color camera. The avionics also incorporate multiple global positioning system (GPS) systems to record the vehicle's precise location and flight path, redundant data acquisition and storage systems, and a variety of data sensors. Plans call for the solid-fuel rocket to zip upward from the desert floor and reach a speed of more than 4000 MPH in about 9 seconds. The suborbital vehicle will attain an altitude of 100 km or 62 statute miles--high enough to be considered 'space'--linger there for a couple of minutes then arc back to Earth some 26 miles down range. The whole thing will take somewhat less than a half-hour. If successful it would mark the first amateur rocket launch into space."

    Does that model rocket come with an airbag?

    Honestly this is rather interesting. I've heard about the problems of establishing a GPS lock after a 25G sustained force- and that it's near impossible. Pulling it off is quite a feat.

    I don't understand why they are returning to earth so soon, however- shouldn't a parachute (which arguably wouldn't provide much slowdown with ~1000 molecules/cm3) delay the reentry more than 1/2 hour? Unless they are expecting to lawn dart ;)

    Here's to their success

      Probably no parachute is a ground safety issue; if they deploy one at that altitude, there's no telling where the thing might land.

      Recovery is a big problem for high power rocketry - how many hours downrange do you want to drive to get your rocket back?

      Normal approach is to eject a small drogue parachute near the apex of the flight, which is intended too let you lose lots of altitude without going to fast. It also keeps you from drifting too far from the launch site. Once you're close to the ground (via redundant altimeters) you eject the main chute to set it down 'relatively' gently.

      I've had my license for ten years next month. I'm not on the air much anymore. Aside from emergency communications and such, the internet has ham radio beat hands down. Packet is STILL capped at 9600 bps as it was when I first got my ticket. Worldwide communications can take place easily over AIM, IRC and the like (no reliance on sunspots, can cuss and use encryption to your hearts content).

      I think there is a great educational value in ham radio, but the kids (who are the new blood to keep the hobby going forward) don't seem to be gravitating towards it in the face of such competition.

      Current hams, please feel free to correct me or debate the above.

    Yes, linger. The vertical velocity of the rocket decreases to 0 at the top of its trajectory and then accelerates downward due to gravity, therefore the rocket will spend a longer time at the top than at any other point in its journey (besides the ground...). Thus linger is the appropriate term.

    Didn't you get the press release? They need to achieve an altitude of at least 50 miles in order for the broadcast to be heard over the interference of your local powerline broadband provider. Space has nothing to do with it.

    I don't know about CATS, but the X-prize (before Ansari stepped up) was funded by insurance -- basically, the X Prize foundation found an insurance company willing to gamble that no one would be successful and the prize wouldn't be awarded. The time limit was necessary before the insurers would assume the risk.

  17. About the launch site... by ikluft · · Score: 5, Informative
    I talked with some of CSXT's Avionics Team about what would happen when this went up on Slashdot. And here it is. We figured it's inevitable that some people will try to show up even though it's short notice and a really inhospitable location.

    Bear in mind that the launch site is far away from populated areas on purpose. Over there in the deep desert, that presents a survival issue for anyone who comes unprepared. There is no city infrastructure that most people are used to - it's a wilderness. If you wander off and get lost and stuck, you may survive for days but not be discovered for weeks. That's why you should take this seriously.

    Cell phones do not work out there. It's well over an hour's drive from the nearest cell site. Amateur Radio and satellite phones are the only reliable communications out there. If you don't have those, don't wander away from the paved roads and the launch site.

    So if I haven't scared you away yet, here's some info that hopefully will help you survive out there. Remember that in the desert, bring your own drinking water - and lots of it. I have a web page about the Black Rock Desert. I have a page with a minimal camping checklist. Even if you're planning to stay in a motel, bring enough camping gear to survive overnight and wait for a rescue if you get stuck. (Overnight temperatures are usually in the 20's and 30's this time of year.) But don't go wandering off where no one knows to look for you. And lastly, see our page about "How to avoid needing a rescue at Black Rock", which we wrote after participating in many rescues of stranded people out there.

    I'm going to be out there with the Stratofox Aerospace Tracking & Recovery Team. We consider it an enormous privilege that CSXT has invited us to assist at their launch.
