During that time frame there were 3 guys that got together and built an amateur rocket that flew to the edge of space. It was a boosted dart, which means the bottom part was a big, fat rocket motor and the top was a skinny but heavy small rocket with no motor. When the lower stage burns out the upper stage drag separates and keeps going (from inertia) until gravity does its thing. They launched it in the Black Rock Desert in Nevada. It had a downward looking camera with a RF downlink for video and telemetry. It hit mach 3.something, and the dart traveled to a bit over 50 miles. I can't find it now, but there used to be a video showing the flight. You saw the earth fall away, and when it hit apogee (arced over), you saw the curvature of the earth and then tons of stars. Unfortunately, it came in ballistic and impacted a few miles downrange. Even with a backhoe, they only recovered a few bits. The story was it took them over a year to build it, and it cost one of the guys his marriage. |

We used to fire them at the Albany, CA police range when no one was around. Probably go to jail these days for doing that. |

You'd be amazed at what's available and what hobbyist are doing with it. To fly the big stuff you have to be a member of a rocketry association (NRA or Tripoli) and have your field registered with the FAA. Then you have to give them advance notice of when you're going to launch, and you are altitude limited depending on your geographic situation. At least that's how it worked when I was active. The biggest thing I built and flew was 6 inches in diameter, stood over 8 feet tall and weighed about 25 pounds. It used a cluster of 5 motors. The biggest cluster I flew in it had 4 times the power (specific impulse in newton-seconds) of a military Stinger shoulder-launched missile. It was good for a little over 8,000 feet. The propellant used is ammonium perchlorate. Basically the same stuff as the solid rocket boosters on the space shuttle. Expensive hobby. |
