This tiny probe the size of your cell phone could measure the gravity of asteroids in 1st space

The European Space Agency (ESA) wants to land a tiny satellite the size of a mobile phone on an asteroid to measure its gravity. ESA has completed vacuum and vibration tests for its Gravimeter for Small Solar System Objects (GRASS) asteroid probe. GRASS is designed to measure surface gravity on the asteroid Dimorphos, which is … Read more
