NASA’s Roman Space Telescope could uncover oodles of potentially Earth-like exoplanets during its survey of our galaxy’s central, star-packed bulge. But astronomers probably won’t be able to learn much more about most of them.

Congrats, @NASARoman team — what an amazing launch! We are excited to follow the telescope’s journey to L2 and can’t wait to see what it reveals about the universe.
Ad astra ⭐
At 7:26am ET (1126 UTC) on Aug. 30, @NASARoman took to the skies en route to its new home 1 million miles away from Earth. It should reach its final destination in one month: go.nasa.gov/4iDR2Hz

What's so cool about the Roman Coronagraph?
Well, it's the first *active* coronagraph in space, meaning that it can adjust itself on the fly to help scientists get the clearest glare-free images.
The @NASARoman Space Telescope is set to launch on Sunday, Aug. 30!

Roman is on her way. 🚀
Years of work, extraordinary engineering, and one incredible launch.
Congratulations to the entire @NASA team and our partners who made this mission possible. The Nancy Grace Roman Space Telescope is about to open an entirely new window into our universe.
Acquisition of signal confirmed for our @NASARoman telescope. We have spacecraft separation, and a last look at Roman, now flying on its own. go.nasa.gov/4chzg9c
