Lowering Costs on the Earth-to-Orbit Run, Preparing for Incoming Asteroids

Getting scared silly by the latest doomsday prediction is silly. So is ignoring real threats.

The Chelyabinsk meteor didn't kill anyone. Only 1,100 or so folks needed medical treatment: for injuries ranging from cuts and bruises to a broken spine. Next time, we may not get off so lightly. Now is a very good time to start getting ready for an incoming asteroid....

Apart from Space Shuttle fleet, now out of service, and recoverable capsules like Space-X's Dragon, launch vehicles are still a single-use technology. That makes getting into space very expensive.

A decade from now, we'll probably see shipping rates go down: dramatically, I suspect.

Reaction Engines Limited's Skylon is scheduled for a test flight to the International Space Station in 2019. Quite a few other spaceplanes are in development, including: DRDO/ISRO's Avatar; Sierra Nevada Corporation Space Systems' Dream Chaser.; and JAXA's HOPE-X.

Any one of them may run into insurmountable obstacles and not fly. But I'll be very surprised indeed if none lead to an economical ferry service to orbit.
