Today's #CRS28 cargo launch is being waved off due to high winds in the recovery area.

Monday's launch attempt is scheduled for 11:47am ET (1547 UTC), with NASA TV coverage beginning at 11:15am ET (1515 UTC).

Two weeks of skis and snowmobiles and snowshoes, temperatures down to -40F, and countless frozen granola bars.

Are you a summer or winter person? ☀️❄️

The Nemuro Strait in these #Landsat images is one of the largest sand spits in Japan. In the summer, sea grass and kelp can be seen in Notsuke Bay, while in the winter, the bay’s shallow waters freeze over.

Astronauts Tom Stafford and Gene Cernan blasted off in the Gemini 9A spacecraft #OTD in 1966 for a 3-day mission to practice docking with a target vehicle and test a new propulsion system on a spacewalk.

Calling all tabletop gamers! Have you ever wondered about the “alignment” of various cosmic objects?

For #InternationalTabletopDay, we sorted some Hubble views of our universe into different alignments. ⬇️

Lawful: Grand design spiral galaxies

“Grand design” spirals earned their nickname because of their very well-defined, distinct spiral arms. Spiral galaxies are actively forming stars and make up a large amount of all the galaxies in our nearby universe!
#Hubble

Neutral: Lenticular Galaxies

These “in-between” galaxies have traits of both spiral and elliptical galaxies: they host a central bulge of tightly packed stars, but they lack arms. Like ellipticals, lenticulars have older stars & little star formation.
#Hubble

Chaotic: Quasars

A quasar is a beacon of intense light from the center of a distant galaxy that can outshine the entire galaxy. Powered by hungry black holes, they devour a lot of gas and dust that gets heated to high temperatures, and they unleash a torrent of radiation.

"This is the greatest experience, it's just tremendous."

#OTD in 1965, Gemini IV astronaut Ed White became the first American to perform a spacewalk, floating for 23 minutes while attached to the spacecraft.

Keep your eyes on the berg 👀 🧊

NASA’s Terra satellite captured Iceberg A-76A splintering into smaller pieces near the remote island of South Georgia. A-76A broke off from A-76 shortly after the initial calving event two years ago. go.nasa.gov/3WJ602h

Glazed, powdered...or filled with lava? It's likely that volcanic activity played a role in forming these donut-shaped craters. The craters are unusual in shape but are fairly widespread on the pockmarked lunar surface.
