Driving down the price of taking people and cargo into space or to the other side of the world in two hours will depend on developing a system so reliable and reusable that a thousand flights or more can take place in a year, a space launch expert told a group of engineers and others Aug. 31 at NASA's Kennedy Space Center.
It's not a launch scenario envisioned for the immediate future, but it could develop in the decades afterward, Jay Penn of Los Angeles-based The Aerospace Corporation said during his "Beyond Next Generation Access to Space" presentation. The company studied potential business cases for pursuing different launch strategies.
The cost of taking a pound of anything into space ran about $10,000 aboard the space shuttle, but that price tag would fall dramatically if space agencies and companies model their research on developing launch systems on the commercial airline and air cargo industries, Penn said.
"Commercial aircraft operate at $2 to $3 per pound of payload around the world, but space is 5,000 times that," Penn said.
Getting the space transportation business down to that cost means building vehicles that are designed for operability -- that is much less maintenance between flights with rapid turnaround to support much higher flight rates. Evolving systems that deliver people and cargo to anywhere on the planet in less than two hours, for example, will need to make multiple trips in the same day and operate out of three or more hubs around the world.
