NASA and SpaceX successfully launched their SPHEREx and PUNCH missions into orbit Tuesday night from Vandenberg Space Force Base in California, to "collect" data on the sun and millions of galaxies.

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.

The missions' first several delays were to allow for additional time for checkouts and processing on the Falcon 9 rocket they'll ride to space, according to NASA. Now, the delay is to "allow SpaceX to complete rocket preparations ahead of liftoff," NASA said in an update.

The postponement, driven primarily by thick clouds, was the second scrub of the flight since an issue with the rocket on Saturday night.

After more than a week of delays, two new NASA missions have gotten the greenlight to head to space tonight (March 8).

The spacecraft, SPHEREx and PUNCH, had been expected to launch on a SpaceX rocket on Saturday. Two NASA missions will have to wait longer for a launch aboard a single rocket. Both aim to unravel mysteries about the universe — one by peering far from Earth,

SPHEREx will create a 3D all-sky map of 450 million galaxies, while PUNCH will use small satellites to study the sun’s impact on space weather and Earth’s communications.
