Sneak peek at what it looks like to set up a new experiment on the @Space_Station! I installed hardware in the Microgravity Sciences Glovebox (MSG) for the Colloidal Solids experiment. This study will investigate the structure and dynamics of crystal, gel and glass phases during solidification of colloids (mixtures in which tiny particles of one substance are scattered throughout another, but that don’t dissolve or settle out, for example, milk, mayonnaise, and fog).  Since gravitational forces often perturb these materials, we may observe differences in microgravity. This research could lead to the development of new materials for space exploration (substrates for plant growth, 3D printing, etc.), and may provide insight into protein crystallization, a critical process in the manufacturing of pharmaceuticals, to directly benefit human health back on Earth.

What’s in the night sky for May? In this month’s episode of “What’s Up,” see how to spot the Eta Aquarid meteor shower, find out when we’ll get a blue moon, and learn more about a celestial meetup between the Moon and Venus. Happy skywatching! go.nasa.gov/4cP2lYU

Your emotional support astronauts… are back. 🌕 On this week’s #HWHAP, we revisit a classic episode from 2023 with the @NASAArtemis II crew recorded just after their selection, to hear their first reactions and reflect on how far they’ve come. go.nasa.gov/3OROqtq

POV: you're rolling around on the Red Planet You’re looking at six years on Mars in around two minutes. This timelapse contains images captured by our Curiosity rover between 2020 and 2026 from one of its navigation cameras. go.nasa.gov/4cH4mrt

Suit up. @NASA's @SpaceX Crew‑13 is almost ready to write the next chapter in orbit. 🧑‍🚀 Launching no earlier than September 2026, the international crew will head to the International @Space_Station for Expedition 75, where they’ll support science and technology demonstrations that advance exploration from the Moon to Mars and benefit life on Earth.

From 250 miles above us in low Earth orbit, the International Space Station has been a home and laboratory for over 25 years. With the Orion spacecraft now taking humans farther than we’ve ever gone before, the Expedition 74 crew aboard the space station offered a symbolic token to the @NASAArtemis II crew and Commander Reid Wiseman as we continue to reach higher and dream bigger in human spaceflight.

I have been playing around with some long exposure shots that show some beautiful effects with our orbital motion. City lights are turned into streaks across the earth, and lightning storms form a speckled pattern during these several-minute exposures.

Busy day at Kennedy Space Center! 🚀 ☑️ Artemis III core stage moved into the Vehicle Assembly Building for integration ☑️ Solid rocket booster segments for Artemis III continue early processing and integration work ☑️ Artemis II Orion capsule is back at Kennedy to undergo post‑flight analysis Momentum is building, as we prepare for the next giant leap! go.nasa.gov/4vWJ2px

STS-100 Pilot Jeff Ashby slowly backed space shuttle Endeavour away, and at a distance of 450 ft (137 m) from the International Space Station, initiated a flyaround 25 years ago today. Its brand new robotic arm, Canadarm2, and communications antenna gleam in this photo from the flyaround. The space station assembly and resupply goals of this mission were complete.

Scientists are studying how the gut microbiome changes in space! 🦠 CBIOMES just wrapped up aboard the space station, and the results could help us improve methods to protect astronaut gut health on future space missions.

Missing updates from the Artemis II crew? We have other humans in space you can follow! Meet the NASA astronauts currently aboard the @Space_Station in the thread below 👇

Ask an astronaut! Anil Menon is set to launch this July for his first spaceflight to the International Space Station. He’ll answer questions live on Wednesday, April 29 at 1:45 pm ET on NASA’s YouTube channel. Reply with your questions below and tune in tomorrow to see if they get answered!

Did you know that the Milky Way is even milkier when viewed from the Southern Hemisphere? This is because from the southern side of our planet, we get a clearer, more direct view of the dense galactic core. Here’s a look at the Milky Way starting over the Southern Ocean (between Australia and Antarctica) from our @SpaceX Dragon window, complete with some aurora (Southern Lights) and fleeting Starlink satellites. Enjoy the view!

In every great leap, there’s a moment that changes everything. @NASAArtemis II became that moment, suspended between past and future and powered by the people who make exploration possible. Each milestone brings us closer to returning astronauts to the Moon and preparing for Mars.

The core stage for the Artemis III rocket has arrived at @NASAKennedy. Watch teams offload this crucial piece of hardware for the mission that will test rendezvous and docking necessary for future crewed landings on the lunar surface: youtube.com/live/oWe8kvpxz…

Passing over Algeria on the @Space_Station always feels like a trip to an art museum. #EarthArt. Which one is your favorite?

We have found over 6,200 planets beyond our solar system, but we still only know of one that is just right for human life — our home on Earth. #MondayMotivation
