Blue Origin, the commercial space company founded by Amazon billionaire Jeff Bezos, launched a package of NASA experiments to the edge of space Wednesday from West Texas with a suborbital New Shepard booster, then successfully recovered the reusable rocket and space capsule a few minutes later.

Japan’s Epsilon rocket delivered a civilian-operated radar imaging satellite to orbit Wednesday on a mission to demonstrate the performance of a new commercial spacecraft design and collect all-weather imagery for use in emergencies, mapping and global surveillance.

SpaceX’s Falcon 9 rocket and Crew Dragon spacecraft emerged from the company’s hangar at the Kennedy Space Center early Thursday for the quarter-mile trip up the ramp to historic Launch Complex 39A, ready for final testing before liftoff on the first U.S. mission to carry astronauts into orbit in nearly nine years.
