Mars Curiosity rover conducts first soil sample test, finds water, sulfur and chlorine
Posted in: Today's ChiliNASA has announced today that the Curiosity rover currently putzing around on Mars has conducted its first, extensive test that analyzed soil samples that the rover dug up previously. The results found a “complex chemistry” in the soil. Water, sulfur and chlorine-containing substances were discovered, along with a few other ingredients.
The soil sample was dug up at a site called “Rocknest” that lies in a relatively flat part of Gale Crater, but still miles away from the rover’s main destination on the slope of a mountain called Mount Sharp. NASA selected Rocknest as the first scooping site because it has fine sand particles that are well-suited for “scrubbing interior surfaces of the arm’s sample-handling chambers.”
The rover’s examination of the dirt samples found that the composition is made up of about “half common volcanic minerals and half non-crystalline materials.” Furthermore, the water that was discovered during testing doesn’t mean that the sample was wet by any means. Water molecules were simply bound to grains of sand, and it’s not unusual, but the quantity that was discovered was higher than anticipated.
Of course, nothing is final yet. NASA says that this is just the beginning of sampling soil on Mars, and the team plans to obviously conduct tons of further tests over the next two years in order to see if Mars once was inhabited with life forms, but the discovery of water molecules is definitely a good sign, and is a step forward for the Mars Curiosity team.

Prior to Android 4.2’s release, many folks were speculating that this could very well be known as Android 4.2 Key Lime Pie to keep up with tradition that required a sweet dessert name to be associated with the next major release of an Android operating system update. Well, unfortunately for pundits and everyone else looking on in interest, version 4.2 of Android retained the Jelly Bean moniker, and hence it is most likely that Android 5.0 will be the candidate to be dubbed Key Lime Pie. The thing is, it can be pretty hard to get a confirmation of that, but Manu Cornet, a Google employee, could have inadvertently made it known to the world in a comic that he posted on his Google+ account, showing off the evolutionary path that the Android green robot is on, shaped in the same way of a human from an ape till today.
If you happen to live in Detroit and are a subscriber of AT&T’s services, were you affected by a reported wide-spread blackout in the metro Detroit area? According to AT&T spokesman Jermaine Spight, AT&T has yet to be able to pinpoint the cause of the blackout, and they are unable to figure out just how widespread this outage is, so the number of users affected is really a guess at best.

It was on December 3, 1992, when the first text message in the world was sent in the UK. Neil Papworth, who is an engineer working in the UK back then, had the honor of sending the first SMS in the world, and instead of something geekier like “Hello, World”, it read a plain and simple “Merry Christmas.” Of course, it must be interesting to note that for humans, most of us would be entering our prime at the age of 20, but for the text message (or SMS, depending on what floats your boat), it could very well be in its twilight years – or at least have gone over the hill.
