NASA says liquid water is on Mars -- so is there life?

Culture
There's flowing water on Mars, but it's a bit briny. I'm Bridget Carey this is your c|net update. Scientists at NASA have discovered there is liquid water flowing on the hills of Mars, suggesting the possibility that there could be life of some kind on the red planet. But we're not talking about a babbling brook. You see, the evidence of water is in the changes of color in the bedrock. There are these dark streaks that are showing up when the temperature gets warmer, and they're flowing downwards. See the grayish lines? Those are the streaks. It was observed from the Mars reconnaissance orbiter, and the ebon flow over time Scientists pointed a spectrometer at the surface and it appears to confirm that it's a very salty water. And even if it's super briny water flowing down, it offers a possibility that there is life on Mars. The martian atmosphere makes it very hard for water to remain a liquid. Normal water on the surface freezes at zero degrees celsius and then boils at just ten degrees. Yes. ten celsius But the salt keeps it liquid at a broader temperature range. so where do we go from here? Well, we're going to Mars. NASA plans to send humans there in the 2030s. And in the meantime, there are several crafts heading up there to probe more and do more work to see what else they can discover about the water and what it can tell us about the planet's past. Water could also be a resource for future explorers But it's a bit too early to say for sure. Scientists believe Mars once had a vast ocean that covered half the planet. If there was life millions and millions of years ago, maybe this water can tel us if any form of that life survived. Meanwhile back on planet Earth. There's another phenomenon that baffles many. The iPhone phenomenon. Apple said it sold 13 million of the new iPhones 6S and 6S Plus models from Friday through Sunday, that's the first three days of sales. It's a new record. Last year, Apple sold 10 million iPhones over the same period of time. One difference is that China was part of the launch day sale this year and it wasn't last year. And Facebook is bringing new life to a product once thought as aridly desolate. I'm talking about Facebook Notes, the place where you can make long forum posts. Facebook changed Notes to look more like a blog post, adding tools to add images, resize photos, and format the layout. Facebook made some example posts on how you could showcase a recipe, or use it as a personal journal. The design may remind you a bit of the long form posts of Medium. You can only create a note from the desktop, not from the Facebook app yet. That's it for this tech news update, and you can explore more at Cnet.com. From our studios in New York, I'm Bridget Carey.
