NASA discovers there may be flowing water on Mars

water on mars

Dark seasonal streaks on crater walls could be flows of salty water.

We have known for a while now that ice exists on Mars.  We have seen a lot of suggestions that liquid water may have once existed on the surface in huge rivers and oceans. But  NASA has announced for the first time, they may have actually spotted some flowing, liquid water.

NASA Wants to Send a Rocket-Powered, Robotic Plane to Explore Mars

ARES (Aerial Regional-Scale Environmental Surveyor)

As a general rule, when NASA flies a scientific mission all the way to Mars, we expect that mission to last for a while. For instance, the Spirit and Opportunity rovers were slated to run for three months and are still operating 6 years later. But one NASA engineer wants to send a mission all the way to the Red Planet that would last just two hours once deployed: a rocket-powered, robotic airplane that screams over the Martian landscape at more than 450 miles per hour.

Time’s Top 10 Scientific Discoveries

1. Large Hadron Collider

Good news! The Large Hadron Collider (LHC) – the massive particle accelerator straddling the Swiss-French border – didn’t destroy the world! The bad news: The contraption didn’t really work either. In September, the 17-mile collider was switched on for the first time, putting to rest the febrile webchatter that the machine would create an artificial black hole capable of swallowing the planet or at least a sizeable piece of Europe – a bad day no matter what. No lucid observer ever thought that would really happen, but what they did expect was that the LHC would operate as advertised, recreating conditions not seen since instants after the Big Bang and giving physicists a peek into those long-vanished moments. Things looked good at first, until a helium leak caused the collider to shut down after less than two weeks. Repairs are underway and the particles should begin spinning again sometime in June.

Mars Express To Make Daring Flyby

Mars Express To Make Daring Flyby 

The European spacecraft Mars Express is to make a daring flyby of the Martian moon Phobos in the hope of gaining insights into its enigmatic surface, temperature and geological past, the European Space Agency (ESA) said on Wednesday.

On 23 July, the unmanned craft will swoop to within just 97 kilometres of Phobos, using a battery of instruments, including a high-resolution stereo camera, infra-red scanner and atmospheric spectrometer.
