As the agency's SPHEREx space telescope and PUNCH solar mission rode toward their orbital stations at 10:09 p.m. EST (0209 March 9 GMT), members of mission control appeared elated, onlookers who caught a peek at the liftoff cheered, and the scientists who built these missions exuded a blend of relief and excitement.

NASA and SpaceX late Monday said they were standing down the launch of the SPHEREx and PUNCH spacecraft missions due to unfavorable weather at the launch site and an issue with one of the spacecrafts.
