NASA’s newest space telescope, called SPHEREx, finally got off the ground this week, after a series of delays that had stalled its launch since late February. From low-Earth orbit, it will gather data on millions of stars and galaxies—and search for the ingredients of life.

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.

SpaceX launch scheduled for Wednesday will carry replacement crew for astronauts who have been stuck on the International Space Station since their troubled Starliner mission.

NASA astronauts Barry "Butch" Wilmore and Sunita "Suni" Williams are closer to getting home, nine months after arriving on Boeing’s Starliner. A capsule is set to arrive at the space station Thursday.

NASA’s newest space telescope rocketed into orbit Tuesday to map the entire sky like never before — a sweeping look at hundreds of millions of galaxies and their shared cosmic glow since the beginning of time.

NASA has scrubbed its launch to take four astronauts to the International Space Station, which is one of the first steps in returning NASA astronauts Suni Williams and Butch Wilmore’s back to Earth. NBC News' Tom Costello has more on the reasons for the scrub.
