Watch as Progress docks with Space Station bringing a holiday delivery

This collection of images from NASA and SpaceX photographers shows the Crew Dragon spacecraft lifting off on top of a Falcon 9 rocket May 30.

NASA unveiled an ambitious program Friday to commercialize low-Earth orbit, making way for product development and even advertising aboard the International Space Station, month-long visits by company astronauts starting as early as next year and use of a station docking port for privately financed research-and-development modules.

One of five CubeSats deployed from the International Space Station last month is testing a steerable drag brake that could find use in future smallsats to return experiment samples to the ground from low Earth orbit, or on low-cost micro-probes to explore other planets.
