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.

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: https://t.co/CpvHRvglau

Space is exposing biology’s limits—and how to fix them: https://t.co/uXCadygZAd

To make microbes produce in space, we may need entirely new systems to improve manufacturing, making production more efficient and resilient.

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: https://t.co/ak34z9EbMq

Just as sugar settles at the bottom of a teacup, gravity causes sedimentation in protein solutions to make LambdaVision’s artificial retinas, designed to restore vision for people with macular degeneration.

Microbes could prove essential to future factories in space—producing materials on demand.

But in microgravity, some shift into survival mode instead of producing.

That’s a major challenge for space manufacturing—and a clue for improving it on Earth: https://t.co/CdTQvtmrcf
