NASA prepares to shut down one of its ‘Great Observatories’
NASA will say goodbye to the Spitzer Space Telescope this week after more than 16 years observing the most distant galaxies ever detected, planets orbiting other stars, and star-forming clouds of dust and gas.

Axiom wins NASA approval to attach commercial habitat to space station
NASA has selected Axiom Space, a Houston-based startup partnering with Boeing and other aerospace contractors, to attach a commercial habitat to the International Space Station and begin constructing an orbiting complex that the company says could ultimately replace the international research outpost.

Solar Orbiter launch delayed to Feb. 7
Officials have delayed the launch of a United Launch Alliance Atlas 5 rocket with the European-built Solar Orbiter spacecraft from Cape Canaveral by two days to Feb. 7, a ripple effect from time spent fixing a minor issue last week during a launch vehicle countdown dress rehearsal.

ULA team completes countdown practice run before Solar Orbiter launch
United Launch Alliance teams loaded super-cold liquid hydrogen and liquid oxygen into an Atlas 5 rocket Friday at Cape Canaveral during a countdown dress rehearsal for a planned launch next month with the Solar Orbiter mission, a robotic spacecraft to study the origins of the solar wind and image the sun's poles for the first time.

Photos: Solar Orbiter encapsulated inside launch shroud

SpaceX releases preliminary results from Crew Dragon abort test
Data from the Jan. 19 in-flight launch escape demonstration of SpaceX's Crew Dragon spacecraft indicate the performance of the capsule's SuperDraco abort engines was "flawless" as the thrusters boosted the ship away from the top of a Falcon 9 rocket with a peak acceleration of about 3.3Gs, officials said Thursday.

Atlas 5 for Solar Orbiter launch returns to assembly building for inspections
United Launch Alliance moved its next Atlas 5 rocket off its Florida launch pad Wednesday for inspections after a cooling duct unexpectedly disconnected before a planned countdown rehearsal to prepare for liftoff next month with the joint U.S.-European Solar Orbiter mission. The roll back to the Vertical Integration Facility at Cape Canaveral's Complex 41 launch pad could delay Solar Orbiter's liftoff, which was scheduled for Feb. 5
