One of the obstacles to long space missions is the muscle loss that astronauts suffer from. It’s called atrophy, and NASA says that astronauts can lose up to 20% muscle mass during missions of only 5 to 11 days. This muscle loss affects what are called “anti-gravity muscles,” including calf muscles, the quadriceps and the …

This is What the Ground Looked Like After InSight Landed on Mars

   16 Jun 01:00:02   |  Universe Today

When InSight landed on Mars on Nov. 26th, 2018, it deployed a parachute to slow its descent through the thin Martian atmosphere. As it approached the surface, it fired its retro rocket to slow it even more, and then gently touched down on the surface. As it did so, its retro rockets excavated two small …
