Free flowing water on Mars needs to be protected from contamination

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.

Life on Mars: Curiosity sends back first rock datings

Life on Mars: Curiosity sends back first rock datings

This week the NASA folks behind the Curiosity Mars rover mission have published a set of papers which suggest that they're closer than ever to finding habitable environments on the planet. These findings are pre-emptive in finding actual organic materials, and show how life could maybe, possibly have existed on Mars at one time. Basically the scientists on this project have said they're confident that there's a possibility of life at this point without literally saying they've found that life outright.

NASA’s “MAVEN” Mars orbiter launched without a hitch

NASA’s “MAVEN” Mars orbiter launched without a hitch

NASA's Mars orbiter MAVEN launched successfully today from Cape Canaveral, Florida at 1:28PM EST. Once it arrives in orbit around the Red Planet, the Mars Atmosphere and Volatile EvolutioN orbiter will gather data about Mars' upper atmosphere to try and discover how exactly the planet got to be so dry and atmosphere-poor. Earlier probes suggest the planet used to be much more like Earth in terms of moisture and atmosphere thickness.

NASA GROVER rover completes first tests in remote arctic expedition

NASA GROVER rover completes first tests in remote arctic expedition

NASA's Curiosity Mars rover may be the agency's latest space-faring rover, but their newest wheeled robot was recently deployed in the cold depths of Greenland. Called the Goddard Remotely Operated Vehicle for Exploration and Research rover (GROVER for short), NASA took it out into the cold weather to complete a round of tests to see how it would fare in negative 22-degree Fahrenheit weather.

Star Trek deflector shield could protect Mars mission from cancer risk

Star Trek deflector shield could protect Mars mission from cancer risk

A Star Trek style deflector shield that could protect deep-space astronauts, such as the much-discussed manned mission to Mars, from cancer-causing levels of radiation is in testing, researchers have revealed. The system, described as a "mini-magnetosphere" in reference to the Earth's magnetic field which protects us from solar radiation, is the handiwork of the Rutherford Appleton Laboratory, and relies upon the fact that by creating a magnetic field around a spacecraft, the dangerous rays can be deflected and the astronauts preserved in a bubble of safety for their journey.

Planetary protection regulations stymieing Mars missions, says researchers

Planetary protection regulations stymieing Mars missions, says researchers

While NASA has been carrying out some extensive missions on Mars, looking for evidence of water and signs that the planet could have supported life, it has been required to follow strict requirements to prevent contamination. The idea behind this is that the introduction of microbes from Earth could harm the Martian planet, something researchers have spoken out against today.

NASA Opportunity rover finds sign of past non-acidic water on Mars

NASA Opportunity rover finds sign of past non-acidic water on Mars

The hunt for evidence of water on Mars that could support life has been a long and exciting one (depending on your definition of exciting). While there is evidence abound of water that used to be on the Martian planet, it has been of the highly acidic variety, which is not conducive to life. Now, however, NASA has discovered evidence of non-acidic water in Mars' past, a finding made by the rover Opportunity.
