NASA's Space Technology Launch Directorate released today infrared footage of a SpaceX Falcon 9 first-stage re-lighting its engine to steer back towards a theoretical landing site.

The booster's landing legs weren't installed for the September 21 launch of the Dragon cargo supply flight to the International Space Station, but it was an opportunity to put the stage through its paces.

According to the NASA press release:

NASA equipped two aircraft with advanced instrumentation to document re-entry of the rocket's first stage. The first stage is the part of the rocket that is ignited at launch and burns through the rocket's ascent until it runs out of propellant, at which point it is discarded from the second stage and returns to Earth. During its return, or descent, NASA captured quality infrared and high definition images and monitored changes in the smoke plume as the engines were turned on and off.

NASA's interest in the flight was potential technology for a Mars mission.

“Because the technologies required to land large payloads on Mars are significantly different than those used here on Earth, investment in these technologies is critical,” said Robert Braun, principal investigator for NASA's Propulsive Descent Technologies (PDT) project and professor at the Georgia Institute of Technology in Atlanta. “This is the first high-fidelity data set of a rocket system firing into its direction of travel while traveling at supersonic speeds in Mars-relevant conditions. Analysis of this unique data set will enable system engineers to extract important lessons for the application and infusion of supersonic retro-propulsion into future NASA missions.”
