Free flowing water on Mars needs to be protected from contamination

NASA has put a number of probes onto the surface of Mars and in orbit around the red planet over the years. Each time NASA launches a mission to Mars, or any other body in our solar system, it takes steps to prevent any contamination of the planet. The problem is that as we explore the planets in our solar system for signs of life, we have to be sure that the life we might discover didn't get there because we contaminated the planet with life from Earth.

Mars hit with thousands of Earth rocks possibly containing life following asteroid impact

Mars hit with thousands of Earth rocks possibly containing life following asteroid impact

Mars has been a playground for NASA's various robots and missions, and it was back in March that the Curiosity rover found evidence of conditions for habitable life, something that has cropped up in various degrees since then. According to some US researchers, it is possible that rocks containing life could have been blasted, so to speak, to the Red Planet from the Chicxulub impact that took out the dinosaurs and many other strikes.

International Space Station coolant failure may demand space walk NASA says [Update]

International Space Station coolant failure may demand space walk NASA says [Update]

A coolant failure has left the International Space Station in an "urgent situation", NASA has confirmed, potentially requiring astronauts aboard to perform a space walk to fix the issue. The problem, short of an "emergency" according to the US space agency, has seen one of the two cooling loops used to regulate station temperature fail, though the six-strong crew onboard is safe.
