Spacewalk happening now. Watch astronauts Frank Rubio (suit with red stripes) and Josh Cassada (unmarked suit) install new

roll-out solar arrays. The spacewalk is expected to last seven hours.

We will host a media teleconference at 11am ET (1600 UTC) on Dec. 22 to discuss the ongoing investigation of an external leak from the Soyuz spacecraft docked to the International Space Station. go.nasa.gov/3jk9qc0
The Nauka multipurpose laboratory module, the Prichal docking module, and the Soyuz MS-22 crew ship are seen on the right of this image, their white exteriors in sharp contrast to the darkness of space. Earth, mostly covered with white clouds, dominates the rest of the photo. Credit: NASA

It’s going to be a long night. In the Northern Hemisphere, that is. Tonight is the #WinterSolstice, which occurs when either of Earth's poles reaches its maximum tilt away from the Sun. This happens twice yearly, once in each hemisphere. Learn more: go.nasa.gov/3vbLGJY

After more than four years, 1,300 marsquakes, and countless scientific discoveries, our
@NASAInSight
lander has reached the end of its mission. InSight may be retiring, but its legacy—and its findings from the deep interior of Mars—will live on: go.nasa.gov/3hND9cP

Today’s spacewalk to install solar arrays has been postponed due to orbital debris tracking near the station. The crew is not in any immediate danger and a new date for the spacewalk will be assessed.

NASA Spacewalk Postponed Due to Debris Avoidance
While flight control teams were preparing for today's U.S. spacewalk, updated tracking data on a fragment of Russian Fregat-SB upper stage debris showed a close approach to station.

@NASAInSight
My power’s really low, so this may be the last image I can send. Don’t worry about me though: my time here has been both productive and serene. If I can keep talking to my mission team, I will – but I’ll be signing off here soon. Thanks for staying with me.
Wide-angle photo from NASA’s InSight lander on Mars shows the area in front of the lander in the late afternoon sun. Two science instruments tethered to the lander rest on the sandy surface nearby. Part of the lander’s robotic arm is visible extending down from the top left. Distortion from the wide-angle lens bends the distant horizon into a curved shape, while low-angle sunlight causes a small bluish lens flare on the right side.

Like water vapor, SWOT rises. SWOT lifted off at 6:46am ET (11:46 UTC). It’s the first satellite mission that will observe nearly all water on Earth’s surface, #TrackingWorldWater to help us better understand this essential resource.

We're now targeting no earlier than 6:46am ET (1146 UTC) on Friday, Dec. 16, for launch of the Surface Water and Ocean Topography mission. The satellite is healthy & the forecast remains favorable for liftoff on Friday morning. Follow blogs.nasa.gov/swot/ for mission updates.

Tonight's spacewalk with cosmonauts Sergey Prokopyev and Dmitri Petelin is cancelled as mission controllers evaluate the impact of a coolant leak seen on the Soyuz MS-22 crew ship. The space station is in good condition and the Expedition 68 crew is safe.

The exterior of the International Space Station, as seen during a flyaround in November 2021. Most, but not all, of the station is visible. Eight long, rectangular solar arrays stick up and down on the far left and right of the photo; at the center, several white cylinders join together at perpendicular angles to make up the ISS's modules, with an array of hardware and other equipment attached. The entirety of the background is taken up by the Earth; snowy mountains, winding rivers and a large body of water are faintly visible.

50 years ago today, Gene Cernan became the last person to stand on the Moon. Before his return to the #Apollo17 lunar module, he said: “We leave as we came and, God willing, as we shall return, with peace and hope for all mankind. Godspeed the crew of Apollo 17.” #Apollo50th

Where did our Moon come from? Over the years, there have been several theories, but the one most scientists agree on is a collision theory. It’s likely that a Mars-sized object smashed into the Earth, creating what we now see in the sky: go.nasa.gov/3uTkYpf

Time to shine. 💫 Don’t miss the annual Geminids meteor shower, peaking between Dec. 13-14. A waning gibbous moon will make it harder to view most of the shower, but the Geminids burn so bright, up to 30-40 should be visible per hour! go.nasa.gov/3FLOAuW
