    Controlling Robots on Mars (from Tested: The Show!)

    Published on Nov 23, 2015

    Bobak Ferdowsi, systems engineer at NASA JPL (AKA Mohawk Guy), was a guest at our recent live show to talk about the challenges of controlling a robot on Mars. To illustrate the communications delay of interplanetary remote-control, Will and Jeremy stage a demo using a reprogrammed RC toy with time-delay controls!

    Mars exploration zones

    Published on Dec 22, 2015

    This concept animation shows just one of many potential concepts for how the first human landing site on Mars might evolve throughout the course of multiple human expeditions to the Red Planet over a decade or more.

    Let's Not Use Mars as a Backup Planet | Lucianne Walkowicz

    Published on Jan 14, 2016

    Stellar astronomer and TED Senior Fellow Lucianne Walkowicz works on NASA's Kepler mission, searching for places in the universe that could support life. So it's worth a listen when she asks us to think carefully about Mars. In this short talk, she suggests that we stop dreaming of Mars as a place that we'll eventually move to when we've messed up Earth, and to start thinking of planetary exploration and preservation of the Earth as two sides of the same goal. As she says, "The more you look for planets like Earth, the more you appreciate our own planet."

    The innermost moon of Mars, Phobos, is seen here in full 360 degree glory. The images were taken by the High Resolution Stereo Camera (HRSC) on ESA's Mars Express at various times throughout the mission's 10 years.

    The moon's parallel sets of grooves are perhaps the most striking feature, along with the giant 9 km-wide Stickney impact crater that dominates one face of the 27 x 22 x 18 km moon.

    The origin of the moon's grooves is a subject of much debate. One idea assumes that the crater chains are associated with impact events on the moon itself.

    Another idea suggests they result from Phobos moving through streams of debris thrown up from impacts 6000 km away on the surface of Mars, with each 'family' of grooves corresponding to a different impact event.

    Mars Express has imaged Phobos from a wide range of distances, but will make its closest flyby yet on 29 December 2013, at just 45 km above the moon.

    Although this is too close to take images, gravity experiments will give insight into the interior structure of Phobos.

    Mars showcase

    Published on Oct 28, 2013

    From the highest volcano to the deepest canyon, from impact craters to ancient river beds and lava flows, this showcase of images from ESA's Mars Express takes you on an unforgettable journey across the Red Planet.

    Mars Express was launched on 2 June 2003 and arrived at Mars six-and-a-half months later. It has since orbited the planet nearly 12 500 times, providing scientists with unprecedented images and data collected by its suite of scientific instruments.

    The data have been used to create an almost global digital topographic model of the surface, providing a unique visualisation and enabling researchers to acquire new and surprising information about the evolution of the Red Planet.

    The images in this movie were taken by the High Resolution Stereo Camera and the video was released by the DLR German Aerospace Center as part of the ten years of Mars Express celebrations in June 2013. The music has been created by Stephan Elgner of DLR's Mars Express planetary cartography team. DLR developed and is operating the stereo camera.

    What Mars looked like 4 billion years ago

    Published on Nov 19, 2013

    Once warm and wet, Mars is now cold and dry. NASA's MAVEN orbiter will look for clues to how the planet's atmosphere has developed, and how density fluctuations might affect future crewed missions

    ESA Unveils Spherical Mars Sample Return Container

    Published on Nov 19, 2013

    The container is engineered to carry 11 receptacles, store them under 14?F (-10?C), and weigh less than 11lbs (5kg). It will land on Mars with a sample providing rover. When it is filled, it will launch and rendezvous with a return-trip spacecraft.

    Bill Nye: NASA can get humans to Mars by 2033

    Published on May 17, 2016

    NASA could get a crew of astronauts to orbit Mars by 2033 without increasing its budget beyond the rate of inflation, says Bill Nye the Science Guy. That's exciting news.

    Transcript - NASA could put humans in orbit around Mars in the year 2033 – 2033 is not arbitrary. It’s when there’s a pretty good orbit - there’s pretty good orbits happening often enough - but 2033 is a real good orbit of the Earth and Mars. So you could get humans in orbit around Mars without raising the NASA budget beyond letting it increase with inflation, which is an increase but not an extraordinary one.

    Furthermore, in order to pull this off without any increase in the NASA budget, everybody has to stick to these agreements that NASA will no longer be the lead funder or supporter of the International Space Station. They’re going to retire the space station or let commercial entities take it over.

    But if you did that, really stuck to the agreements and you let the NASA budget increase with inflation you could have humans orbiting Mars in 2033. If the Mars 2020 rover is enabled to land in a place where there might be salty water - or ancient salty water - and were to discover evidence of life, perhaps we would accelerate that schedule.

    And as we say if you really have a plan to really put humans orbiting Mars in 2033 which would enable them to land two, three or four years later to land on Mars. People would come out of everywhere to volunteer for that mission. We’d have astronauts. We’d have mission controllers. We’d have engineers. We’d have venture capitalists enabling new technologies to be sold to NASA or other space stations.

    If you included other space agencies around the world – Roscosmos, the Russian space agency. Chinese space agency, even which is politically difficult but nevertheless possible. Any space research organization – JAXA, the Japanese aerospace exploration agency. If you included all those guys you could lower the price for NASA and then really enable humans to get there in new, cool ways.

    The reason though, everybody, is not to go live on Mars. That’s just beyond – they just haven’t thought through how difficult that is. When there’s nothing to breathe, not just nothing to drink or eat but nothing to breathe it makes it complicated. But if you were to find evidence of life it would change the course of human history. Not overnight but over the course of months and years. Everybody would get to thinking about what it means to be a living thing in the cosmos and it would change us.
