As the agency's SPHEREx space telescope and PUNCH solar mission rode toward their orbital stations tonight (March 11) at 11:10 p.m. EST (0310 March 12 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.

Following a successful launch in the early hours of Wednesday morning (12 March 2025) U.K. time, the PUNCH spacecraft are poised to begin their two-year mission to study the sun's outer atmosphere and its transformation into the solar wind.

The SPHEREx telescope will create the most colorful map of the cosmos, while the four satellites of the PUNCH mission track the evolution of the solar wind in three dimensions.
