Wondering what that big NASA announcement planned for today was all about? Wonder no more. The dark features, which can reach 5 meters wide and more than 100 meters long, were first noticed in 2010. By analyzing their reflected light signature, a team of eight scientists has concluded that the streaks consist of mineral salts that easily absorb moisture—and that flowing water is the likeliest explanation for their appearance. Flowing liquid water on Mars.
While Curiosity was busy going through it’s seven minutes of terror, the Mars Recon Orbiter was taking pictures overhead. Yes, you heard that right. We took a picture of a tiny little lander descending through the Martian atmosphere with another robot which currently orbits Mars.
Need some help getting ready for Sunday’s MSL landing on Mars? BoingBoing has details of all the online NASA livestream events where you can watch the landing (more or less) live. Landing should occur at 10:31pm Pacific time on Sunday night. It’s great timing for the west coast, I might make a little Google hangout for anyone else watching on Sunday.
