SpaceX and a Houston company are gearing up to launch four private citizens Friday on the first NASA-sanctioned, fully commercial flight to the International Space Station, a key step in a government push to encourage private-sector development on the high frontier.
NASA officials said Tuesday they are standing down from a cryogenic loading test on the agency's Space Launch System moon rocket until after the launch of a commercial crew mission from a neighboring pad at the Kennedy Space Center. A countdown test Monday was delayed by what NASA managers characterized as minor issues, including a liquid oxygen temperature concern and a manual valve that was left in the wrong configuration before teams evacuated the SLS launch pad.
Gearing up for its first mission of the year, United Launch Alliance rolled an Atlas 5 rocket to its launch pad at Cape Canaveral Thursday, a day before liftoff with a pair of U.S. Space Force satellites on a flight that will debut a version of the Atlas 5 never used before.
SpaceX plans to land a Falcon 9 rocket booster back at Cape Canaveral around eight-and-a-half minutes after launch Thursday in the company's first onshore rocket recovery since last June.
Engineers activating the James Webb Space Telescope decided Sunday to hold off tightening up the observatory's critical sunshade to allow more time to check out the performance of its power systems and overall behavior now that several major deployments are complete.
