Captain HiRISE, Space Detective Beams Martian History Album To Earth

Mars, that ever-changing and beautiful Red Planet practically next door to us, is one of the most well-studied places humans have in the universe. We’ve sent spacecraft there for about 50 years. Yet there’s still a lot of mysteries out there.

NASA’s Mars Reconnaissance Orbiter is among the investigating spacecraft in the area checking out the planet’s past and looking for any interesting clues to tell us more about how Mars — and the Earth, and the solar system, and planets in general — formed. Mars had a wetter past (as the rovers have showed us), but where the water went and why its atmosphere are so thin are among the things scientists are trying to understand.

Luckily for us, the catalog of the University of Arizona’s High Resolution Imaging Science Experiment (HiRISE) is easily available online for all of us to marvel at. Here are just some of the pictures sent back from across the solar system. To see more, look below and check out this HiRISE web page.
