Launched from Nevada's Black Rock Desert, the 21-foot Civilian Space Xploration Team (CSXT) GoFast rocket quickly attained the 100 km altitude to make Amateur Radio and amateur rocketry history. Two earlier CSXT attempts to reach space--the last almost two years ago--were unsuccessful. A jubilant Avionics Team Leader Eric Knight, KB1EHE, called the successful launch "a phenomenal experience."

    "It just roared off the pad and flew into space," said Knight, who lives in Unionville, Connecticut. "Everything went like clockwork this morning, and it was an awesome experience. We're all kind of on an adrenaline high right now."

    The GoFast vehicle--named for one of the project's commercial sponsors--lifted off from the desert floor at approximately 11:20 AM PDT. The CSXT team, plus observers from the Federal Aviation Administration, were up and at the launch site several hours beforehand, however, and Knight said the rocket crew--which includes several radio amateurs--did a "dress rehearsal" prior to the actual countdown and launch.

    Knight said several West Coast hams who learned about the rocket launch from ARRL news accounts showed up to assist in locating the vehicle, which was estimated to have returned to Earth some 26 to 30 miles downrange from the launch site. Knight said Monday evening that the rocket had not yet been recovered, but the ham radio telemetry package was continuing to transmit.

    "We have a telemetry beacon telling us where it is--that it's alive and waiting to be found," Knight said. The rocket transmitted telemetry on the 33-cm amateur band and color Amateur TV pictures on 2.4 GHz. An HF special event station, K7R (for "rocket") didn't get much airtime, Knight said, "because we've been really focused on the mission."

    "Everything came together very well," Knight said. His avionics crew includes eight Amateur Radio licensees, most of whom also were involved in the 2002 launch attempt. Former Hollywood stunt man--Ky Michaelson of Minnesota, directs the 18-person CSXT team.

    Thats not even close to being correct. Centrifugal force is a myth. Nothing is pushing the orbiting body outwards. If gravity was to suddenly be turned off, the orbiting body would depart tangentially, not radially as you imply with your "centrifugal" force. A body in orbit is essentially falling continuously to Earth, its horizontal velocity component means that it just keeps missing.

    People go pro with thirty year old pentax 35mm SLRs, so long as they can produce quality pictures and sell them to people. Crap pictures that no-one will buy from an expensive camera just make someone an amateur with a good camera. By definition, you are a professional at whatever your profession is - whatever you make the money at. Many amateur athletes are a lot better at what they do than the professionals - they just don't make any money out of it.

    Orbital craft are launched straight up because it is inefficient to try to accelerate tangential to the Earth's surface at low altitudes, due to the air density. They fly more or less straight up to about 30km before really pitching over to start the tangential acceleration into a periodic orbit (as opposed to a once-through orbit like the one you enter when you jump off the ground). Low earth orbit basically begins around 130km, where the atmosphere has thinned out enough that you can remain in orbit. I think the ISS is in the 230km-300km range.

    I'm going to plug a great simulator for you all, and that is Orbiter. You'll learn a ton about astrophysics just by starting the program up and trying to get into orbit your first time, and it won't quit from there.

    Centrifugal force is a myth.

    Centrifugal force is highly real, as you will no doubt feel if you place yourself on a merry-go-round. It's just a matter of having an accelerated frame of reference. If you and your friend were orbiting the earth, and gravity were turned off for him, the centrifugal force would indeed make him depart radially from you, though the Coriolis force would eventually bend his path.

    That is not entirely true. As a dancer you can simply declare yourself "pro" and start entering competitions for professionals.

    On the other hand in many countries amateurs teach and do demonstrations and get paid for all of these, though usually there are some limits. The distinction between amateur and pro is pretty arbitrary really... In the case of space rockets i think amateur has come to mean "not financed by the government or a business with intent of making a profit", or something similar.

    > We use the term "amateurish" to talk about things which are crappy and I really think this
    > helps to add to the confusion.

    In the sometimes rather bizarre dancing world "amateurish" can actually mean the opposite. In this case it is a distinction to the social dancer. In this case "looking like an amateur" means to look like a serious competitive dancer...

    It kind of scares me that there is no mention of laws relating what, how, who can launch into space.

    So what would be your answers to these questions?

    1. What shouldn't go into space?

    2. How should things go into space?

    3. Who can go into space?

    I ask these questions because I wonder what you're really worried about. After all, there's nothing really dangerous getting lauched into space at the moment. So why do we need laws now? My answers to the above questions.

    1) We already have regulations for dealing with terrorist attacks and other means of deliberately inflicting harm. Further, the history of using rockets for terrorist attacks is pretty ineffective. Military grade rockets are relatively easy to come by. The sole exception to this rule appears to be Hamas in the West Bank and Gaza Strip. They seem relatively insistent on building the Qassem rocket. Note that these terrorist activities are already illegal.

    The US already requires lauchers to purchase insurance against third party harm seems to fix the other problems with what can be launched from Earth. If it's too dangerous, then the launcher won't be able to afford the insurance.

    2) We don't need to regulate "how" things get into space. Physical law does a more than adequate job here.

    3) I don't get why we need to regulate who gets into space.

The SpaceShipOne launch last week & this amateur rocket are further examples of how science doesn't sell. If the thing had exploded on the ground & killed half the team, THAT would be news. If SpaceShipOne blows up or crashes into a trailer park, the media will be all over the story. But if they have another ho-hum flight where nothing goes wrong, it ain't news. Apollo XIII, anyone?
