The growing amount of space debris in low Earth orbit poses a threat to space station operations and critical satellite services. Here’s how Kall Moris Inc.’s REACCH system aims to help keep Earth’s orbit usable: ow.ly/GkUY50ZhhEk #ISSResearch #SpaceDebris #OrbitalSafety

Happy Independence Day from the ISS National Lab 🇺🇸 #250th

During a seven-hour-and-20-minute extravehicular activity, NASA astronaut and Expedition 74 flight engineer Chris Williams humorously flexes for the camera while working to replace a malfunctioning wrist joint on Canadarm2, the ISS robotic arm. 📸 @NASA

NASA astronaut Jonny Kim marks the Fourth of July in 2025 with a portrait in the ISS cupola, the station’s “window to the world.”

Age-related macular degeneration and retinitis pigmentosa cause blindness in millions of people. Gravity interferes with the production of artificial retinas on Earth. That’s why LambdaVision took its manufacturing to space: ow.ly/4xLw50ZhgW4 @lambdavision-inc @spacetango

NASA astronauts Christina Koch and Victor Glover share a view from Orion on Artemis II Flight Day 6, the lunar flyby. The crew rotated roles taking photos, annotating, and recording observations of the Moon’s surface. @NASA #artemis #orion

NASA astronaut Jessica Meir tests her spacesuit inside the ISS Quest airlock, checking mobility, comms, and life support ahead of a June 30, 2026 spacewalk to repair Canadarm2.

Space is exposing biology’s limits—and how to fix them: ow.ly/nC3r50ZgS1K To make microbes produce in space, we may need entirely new systems to improve manufacturing, making production more efficient and resilient. @ASU @USNRL #SpaceBiology #Biotech #ISS

NASA astronaut and Expedition 74 flight engineer Chris Williams is pictured outside the International Space Station during a spacewalk to complete installation of a modification kit ahead of future solar array installation on the orbital outpost.

Gecko feet inspired Kall Morris Inc.’s REACCH system, which uses a micro patterned adhesive to grip objects in orbit. By attaching and pushing, REACCH can move objects in orbit much larger than itself: ow.ly/pMcz50Za7oL #ISSResearch #SpaceDebris #Microgravity
