Wanted: Reusable spaceplane to launch satellites

So DARPA wants a reusable spaceplane. I mean, who doesn’t? For decades, space experts have tried to design quick-turnover, reusable launch systems. So far, however, no one has made one that works. “There really isn’t any kind of vehicle today that does exactly what they’re asking people to do,” Micah Walter-Range, director of research and analysis at the Space Foundation, tells Popular Science. …

Here’s how the dream goes: Our fictional rocket would blast off at hypersonic speeds. Once it reached the right altitude, it would release any upper stages (and payload) it might have. Then it would turn back toward the Earth and land gently someplace where engineers would be able to fetch it, polish it up, and stick it back on the launch pad. Theoretically, reusable rockets should cut the costs of launches enough to open up space to more groups, such as students and startups, and ease NASA’s financial burdens. …

A few different groups have been working toward this goal recently. Last week, the U.S. Defense Advanced Research Projects Agency announced it awarded three teams contracts to make initial designs for just such a reusable small-satellite shuttle. One team is led by the Boeing Company, working with Blue Origin; Masten Space Systems, working with XCOR Aerospace, leads another; and Northrop Grumman Corporation, working with Virgin Galactic, make up the last. Meanwhile, SpaceX announced yesterday it completed a successful test on its way to making a reusable Falcon 9 rocket.

DARPA calls its version of this project Experimental Spaceplane 1, or XS-1. What the agency wants for XS-1 is unique. The craft should launch 3,000-pound to 5,000-pound unmanned payloads to low-Earth orbit for less than $5 million per flight. The whole launch process needs to be streamlined, too: DARPA wants to see 10 flights in 10 days.
