Spaceships pushed by LIGHT – the future of space travel?
What if you could power a ship using sunlight instead of wind? Well in space, you can! Solar sails or light sails are pushed with light from the sun. Photons provide a kick when they reflect off the sail pushing the sail like an air...

NASA | Mars Atmosphere Loss: Plasma Processes
Mars's thick early atmosphere was likely lost to space, and the Sun is a potential culprit. When high-energy solar photons strike the upper Martian atmosphere they can ionize gas molecules, causing the atmosphere to erode over time.
