From: Ed Sent: 26 March 2014 02:15To: EdSubject: Space Technoloty – Info The F-15 ASAT aircraft launched a missile and killed a satellite in 1985. That was one of my programs. The F-15 released its missile at 80,000 feet. A low Earth orbit (LEO) is an orbit around Earth with an altitude between 160 kilometers (99 mi) [522,000 feet], with an orbital period of about 88 minutes, and 2,000 kilometers (1,200 mi), with a period of about 127 minutes. Objects below approximately 160 kilometers (99 mi) will experience very rapid orbital decay and altitude loss.[1][2] With the exception of the manned lunar flights of the Apollo program, all human spaceflights have taken place in LEO (or were suborbital). The altitude record for a human spaceflight in LEO was Gemini 11 with an apogee of 1,374.1 kilometers (853.8 mi). All manned space stations to date, as well as the majority of artificial satellites, have been in LEO. The X-15 could reach an altitude of 67 (353,000 feet) miles in 1963. That was 50 years ago. Further rocket boosters put it into low earth orbit for a short period of time and were classified. A magnetic rail system going up a mountain side could easily replace a first stage to orbit and we’ve had this technology since the 80s. The second stage or aerospace (Space Fleet) plane could easily obtain low or medium earth orbit. Even without the T. Thompson Brown, or the Benfield-Brown technology or the gravity warping or the elusive anti-gravity technologies we should have easily achieved a low cost two stage to orbit capability by 1990. Then once the payloads or parts were in orbit, larger inter-solar space fleets could have been and have been built. The US isn’t about to admit we have a Space Fleet with space ships. I’m not talking about satellites, space telescopes, and space based anti satellite and anti missile systems. If you do enough reading, research and digging, you will know almost as much as I know and can’t talk about.Ed Comparison of space launch methods
