"The PRIMA mission is humanity’s next window into the deep universe."

The SR-71A Blackbird is considered the fastest plane ever made, and now NASA is trying to bring it back, although it's not clear why.

NASA’s Roman Space Telescope has demonstrated remarkable pointing stability and given its powerful planet-imaging coronagraph its first look at the cosmos. The telescope can already stay locked on a target with precision comparable to aiming a laser at a dime from about 150 miles away.

The two missions, falling under NASA’s Commercial Crew Program, will switch roles onboard the ISS before Crew-12 will fly back to Earth.

An attempt to save NASA’s $500 million Neil Gehrels Swift Observatory from dropping out of orbit fell short, but the behind-the-scenes machinations required just to make a rescue possible deserve recognition,

NASA employees say they've lost vital equipment and staff needed to make sophisticated spacecraft amid the agency's abrupt relocations over the past several months.

NASA is taking applications for its next group of flight directors, opening a path into one of the agency’s key mission control roles.

The first in a new class of space telescopes is on track to reach the launch pad in the early 2030s, NASA announced this week. The PRIMA mission will be the first of NASA’s Probe Explorers, a new line of observatories intended to do more science for less money.

Look up at the night sky with the naked eye and it may seem like it rarely changes. Yet the universe is in constant flux. Stars drift through space, orbiting the center of the Milky Way as planets orbit them.
