NASA, SpaceX Share Data On Supersonic Retropropulsion
Data-sharing deal will help SpaceX land Falcon 9 on Earth and NASA put humans on Mars

An innovative partnership between NASA and SpaceX is giving the U.S. space agency an early look at what it would take to land multi-ton habitats and supply caches on Mars for human explorers, while providing sophisticated infrared (IR) imagery to help the spacecraft company develop a reusable launch vehicle.

This is the kind of thing that NASA couldnt have done five years ago, says Braun, who was chief technologist for the agency in 2010-11.
He learned that the hard way. After returning to Georgia Tech, Brauna specialist in entry, descent and landing (EDL)worked with engineers from the university and various NASA centers to develop a proposal for a $50 million sounding-rocket program to flight-test supersonic retropropulsion (AW&ST May 20, 2013, p. 30).
NASAs Space Technology Mission Directorate (STMD) rejected the plan because of its cost, Braun says. But the agency still needs a way to land payloads weighing more than 20 tons to support a human expedition to Mars, leading Braun and his colleagues to find common cause with SpaceX.
