The rover will look for past habitable environments, find biosignatures in rock and will test those samples back on Earth. ", But now, decades later, there are more and more promising signs. Check out Dr. Marc Rayman's answers to more questions. $window.unbind('scroll'); Many of the studies of Mars will involve robots, like the ones that have gone there before, but getting more advanced with each flight. If there was a measurable reaction in the first and not the second sample, that would suggest biological forces at work -- and that's exactly what happened, according to Levin. $video.removeClass('stuck'); NASA's 5th Mars Mission: Timings. 8 killed, including 6 US citizens, in helicopter crash in Egypt. Without a magnetic field on Mars and with much, much less air than on Earth, more harmful space radiation reaches its surface. A Digital Video Broadcast-compliant Integrated Receiver Decoder is needed for reception.

But you don't have to wait, because you can blast off on a Mars Adventure of your own right now! Mars 2020 will also test oxygen production on the planet and monitor Martian weather to evaluate how potential human colonies could fare on Mars. Earth is the only place that we know for certain supports life. But if scientists fail to find evidence of life, that won't end the hope for human exploration. This is an idea that has intrigued people for centuries, and one that I, perhaps like you, have wondered about for most of my own life. While not officially part of the life experiments, the cameras did show us that there weren't any large creatures wandering around! var windowScrollTop = $window.scrollTop(); "The astonishing fact is that there is none. News briefings and launch commentary will be streamed on NASA TV, NASA.gov/live, YouTube.com/NASAJPL and Ustream.tv/NASAJPL. $videoWrap.height('auto'); He proposed that the LR experiment be repeated on Mars, with certain amendments, and then have its data studied by a panel of experts. url : "/layout/mars2020/watch-launch-show.html?" While robotic spacecraft have given us wonderful views, no humans have ever tried to journey to Mars, and no such missions will be attempted for many years. }); // console.log(videoBottom); dataType: "text", $video.removeClass('stuck'); But where is the best place to look for life? In the experiment, the Viking probes placed nutrients in Mars soil samples -- if life were present, it would consume the food and leave gaseous traces of its metabolism, which radioactive monitors would then detect. Enjoy a virtual tour of the Martian surface webcam feed - Red Planet Exploration from NASA’s rover on the planet Mars! var $close = $('.close-video'); One of these landers worked there for nearly 4 years and the other lasted more than 6 years.

Scottie Andrew and Richard Stenger contributed reporting. $videoWrap.height(videoHeight); One of these landers worked there for nearly 4 years and the other lasted more than 6 years. We need a close-up look at the planet. "Inexplicably, over the 43 years since Viking, none of NASA's subsequent Mars landers has carried a life detection instrument to follow up on these exciting results.
