So the folks at NASA are thinking about testing a linear launch system. It would uses linear induction motors like rollercoasters are using now. The trakc would be about 5 miles long and eventually curve up I sure. Once at the end the space vehicle will have gained enough momentum to get into space. I want to know, is this practical? I mean to get a craft into space would require tremendous velocities. The thing would be moving so fast I assume the wheels would burn off. It wouold almost definetly need to be maglev. Going at mach 28 would either take a very small aerodymanic vehicle or a big extremly stready track. Wonder how long the track would last.
