Tense, public squabbles between SpaceX CEO Elon Musk and NASA have stirred the space industry, but behind the scenes, space science has continued business as (almost) normal.

The $488 million Spherex mission aims to explain how galaxies formed and evolved over billions of years, and how the universe expanded so fast in its first moments.

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.
