NASA is finally looking to dump rockets. Yes, rockets did some impressive things–back in the day. But now everyone is using them to get to space. The Chinese. The Indians. Even some Danish yahoos with spare parts they found in their garage. NASA is correct. Rockets are officially lame. So, what is a fashionable national space program with a multi-billion dollar budget to do?
How about hitting the rails?
That’s exactly what NASA’s new Advanced Space Launch System program (which will hopefully get a sexier
name at some point) is looking to do. Railgun technology has been around for nearly a century. It works by creating a strong magnetic field that accelerates a projectile along a set of horizontal metal rails, like train rails. And it can generate some real power. In 2008, the US Navy tested a railgun that launched a projectile 2.4 km per second.
That’s seven times the speed of sound.
We’re not yet at the point of development that we can railgun it into orbit. Not yet. But NASA is looking to tweak these existing technologies to see if they can make a feasible prototype. The ASLS has created a 10-year plan that would begin launching drone-like vehicles, followed by more advanced models that would eventually be able to launch a small satellite into orbit.
Choo choo to where no man has gone before.
