Spaceflight 🚀Kilometer-Scale #SpaceStructures will rely heavily on recent advances in mechanical metamaterials that have shown the potential to expand to 150 times their compressed size. It could rotate to create artificial #gravity without giving its inhabitants motion sickness 🤢 https://www.me.washington.edu/news/article/2021-02-25/nasa-selects-lipton-futuristic-space-concept
A high-expansion-ratio structure can be deployed to a final length of one kilometer on #orbit 🌌 as part of a large #SpaceStation https://www.nasa.gov/general/kilometer-scale-space-structures-from-a-single-launch-2/
