Soft landing

Space.com has an article by Harrison Tasoff about a new form of parachute:

A new NASA nanosatellite is testing a cross-shaped parachute, called an Exo-Brake (photo, above), which could allow small satellites to return to Earth without the directional aid of rocket boosters.
NASA launched the TechEdSat-6 to the International Space Station on 12 November 2017. This nanosatellite is the sixth installment in NASA's Technology Educational Satellite series, a project that tests different tracking and communication technologies. TechEdSat-6 is the fourth satellite to test the Exo-Brake. The satellite was released into low-Earth orbit on 20 November 2017 to begin its experiments, deploying its Exo-Brake once it was safety away from the space station. The agency released an unbloggable video of the satellite's deployment.
The current version of the Exo-Brake uses struts and flexible cords to warp the parachute, "much like how the Wright brothers used warping to control the flight behavior of their first wing design," Marcus Murbach, the device's inventor, said in a previous NASA statement. Engineers will be able to use the device to steer nanosatellites to desired landing sites without using fuel, which adds significant weight to a space-bound payload, according to this NASA statement. Currently, small satellites would have to fire rocket boosters to control their direction as they de-orbit. Small satellites are relatively quick and inexpensive to develop, build, and deploy compared to conventional satellites. As a result, they've become increasingly important in space, military, and telecom research. The Exo-Brake would offer a low-priced way to return samples to Earth from the space station or other orbiting platforms, NASA. What's more, engineers are looking to use the device to de-orbit satellites once they have completed their missions, which would combat the growing threat of space-junk accumulation in orbit, according to TechEdSat-6's mission profile. NASA also hopes to build on the technology to develop systems that could land small satellites on other celestial bodies, like Mars, according to the statement that accompanied the video.
