Chemistry Breakthrough: Faster and Cheaper Ethanol-to-Jet-Fuel on the Horizon

Asteroid 2021 ph27 only needs 113 days to go around the Sun: only the planet Mercury goes faster

One material with two functions could lead to faster memory

Millennium Space in an experiment de-orbited a satellite in eight months. Tethers’ tape creates additional surface area that interacts with the Earth’s atmosphere to create drag, which draws satellites back to Earth faster. The tape is deployed when a satellite is ready to de-orbit.
