NASA’s Curiosity rover touched down on Mars and it’s been flying around, drilling into the floor, shooting lasers in stones, and performing science experiments since. A week, news arrived that Curiosity had found something . The rover is driving round Gale Crater and contains discovered salts.

Scientists think that is due to a time when water evaporated, leaving the salts behind. Our own Earth remains wet so we can readily survive, because we’ve got an atmosphere and a magnetic field, which will keep our entire world healthy and watery. However, the story for Mars can be a bit more complex. Billions of years ago, Mars had an atmosphere however it had a magnetic area that is rather small, therefore the solar winds out of sunlight stripped the atmosphere away with time–leaving the arid, arid planet we have grown to love to it.

The Mars Reconnaissance Orbiter is just a work horse satellite that has brought some of the very photos of Mars . These blue slopes and hills are the floor of Gale Crater. In these HiRise camera images, the blue represents the type of material on earth, which would be exceedingly nice sand. The HiRise camera creates these false colors processingwater might be indicated by — black , such as.
