Video: 00:02:10 Detect, fetch and collect. A seemingly easy task is being tested to find the best strategy to collect samples on the martian surface, some 290 000 km away from home.Testing technologies for Mars exploration is part of the daily job of Laura Bielenberg, an ESA young graduate trainee for the Mars Sample Return campaign.The test takes place at the rock-strewn recreation of the Red Planet at ESA’s ESTEC technical centre in Noordwijk, the Netherlands. The nickname of this test site is the ‘Mars Yard’ and is part of the Planetary Robotics Laboratory.The tube is a replica of the sample caches that NASA’s Perseverance rover is leaving on Mars hermetically sealed with precious martian samples inside. They are called RSTA, an acronym of Returnable Sample Tube Assembly, and to most people on Earth they look like lightsabers.Laura is investigating sample tube collection strategies, from autonomous detection to pose estimation of sample tubes on...
