Hayabusa2 spacecraft managed to capture breathtaking pictures of the surface of asteroid Ryugu. According to the team of European and Japanese scientists who analyzed newly-released photos that Hayabusa-2 s robotic lander, MASCOT, took from the asteroid s surface back in October 2018, rocks on the surface of Ryugu bear a striking resemblance to rocks from meteorites that have crashed down on the Earth.
"Although impact processes dominate the surface geology on Ceres, we have identified specific color variations on the surface indicating material alterations that are due to a complex interaction of the impact process and the subsurface composition." -Ralf Jaumann, Dawn scientist

The strength of HRSC is to perform high resolution digital terrain models of the Martian surface in order to provide topographic context for the geoscientific evaluation of surface processes in space and time,” HRSC Principal Investigator Ralf Jaumann said in a press release.
Martian seasons last twice as long as Earth seasons (and a year is double what a year is on Earth) because of its longer orbit. The body art on Mars is usually covered up by ice around 250 miles across and nearly a mile thick. Not much of it is water ice, so future Mars-tronauts are going to have to look elsewhere for drinkable water that could also double as a source of hydrogen for rocket fuel, unless they want to dig. There might be subsurface water on the south pole, but most of its ice is actually frozen carbon dioxide, or dry ice. It doesn t melt with the heat but instead sublimates, or morphs straight from a solid to a gas. Co2 released from that dry ice makes the atmosphere thicker until winter freez
