NASA's chief says he wants to step up flight opportunities for astronauts.
In a tweet Friday (June 19), NASA Administrator Jim Bridenstine said his space agency plans to drop a request for information (RFI) next week to fly astronauts on commercial suborbital spacecraft.
"Whether it's suborbital, orbital, or deep space, NASA will utilize our nation's innovative commercial capabilities," Bridenstine said in the tweet. No flight dates have been announced yet.

RFIs are competitive processes for NASA to make an informed choice between proposals from private companies based on qualifications it defines for participants. There are some likely leading contenders for the opportunity.
Blue Origin is one of them, and the company has already publicly expressed interest in taking part. "Fantastic news and we applaud your leadership @JimBridenstine for continuing to bolster public-private partnerships in space," Blue Origin tweeted Friday. "We're looking forward to the opportunity to expand New Shepard's human space flight offering to @NASA astronauts."
Blue Origin is developing a New Shepard spacecraft-rocket combo designed to send astronauts into suborbital space. New Shepard is already making uncrewed scientific commercial flights into space — most recently in December, with NASA as one of the customers. In April 2020, a Blue Origin led-team was one of three entities selected to build human-rated moon landers for the Artemis program.
Virgin Galactic is another likely company lining up for the opportunity, although the company has not made any public announcements yet. In December 2018 and February 2019, the VSS Unity SpaceShipTwo spacecraft made two successful test runs past an altitude of 50 miles (80 kilometers), which the Federal Aviation Administration defines as the boundary of space. (This is not quite as high as the internationally accepted Karman line, with an altitude of 62 miles or 100 km).
Another possible applicant is Sierra Nevada's Dream Chaser, a reusable plane-like orbital spacecraft; Sierra Nevada also made no announcement on Twitter about Bridenstine's offer. Dream Chaser received early-stage commercial crew development money from NASA, but did not qualify for the final opportunity to fly astronauts.
In August 2019, Sierra Nevada said it is still developing two variants of the vehicle — one for cargo, and one for astronauts — for future customers. The cargo variant will be used for NASA supply runs to the International Space Station starting around 2021.
Bridenstine's announcement comes three weeks after NASA and SpaceX successfully flew astronauts into space. NASA astronauts Bob Behnken and Doug Hurley piloted SpaceX's commercial crew vehicle, Crew Dragon, as part of the Demo-2 flight to the International Space Station.
Boeing is developing a Starliner spacecraft expected to make similar flights in the near future. In 2014, Boeing and SpaceX received final-stage development contracts from NASA to make their commercial crew spacecraft a reality.
