Nevertheless, the mission team wants to make sure the lander and its instruments can do their job, even if the terrain is tilted as much as 15 degrees.<\/p>\n<p><iframe title=\"Engineering For Mars: NASA InSight Mission Test Lab (360 Video)\" src=\"https:\/\/www.youtube.com\/embed\/ZSXnw-fJbGk?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen=\"\" data-ratio=\"0.5625\" data-width=\"800\" data-height=\"450\" style=\"display: block; margin: 0px; width: 800px; height: 450px;\"><\/iframe><\/p>\n<p>So engineers filled the testbed with crushed garnet to simulate the blend of sand and gravel that InSight is expected to encounter at its planned landing site on the plains of Elysium Planitia. Then they set up a replica of the lander, complete with a deployable seismometer, wind shield and heat-flow probe.<\/p>\n<p>The simulated Martian soil can be piled up at different inclines to test how best to deploy InSight\u2019s instruments in a variety of scenarios.<\/p>\n<p>Marleen Sundgaard, InSight\u2019s testbed lead at JPL, said one challenge has to do with how to keep from tangling up the power cables that connect the instruments to the lander. \u201cWe have multiple places where we could put each instrument down,\u201d Sundgaard said today in a news release. \u201cThere are scenarios where the tethers would cross each other, so we need to make sure they don\u2019t snag.\u201d<\/p>\n<p>The testbed also recreates the reddish-yellowish color of sunlight that filters through Mars\u2019 dusty atmosphere, in order to calibrate InSight\u2019s cameras.<\/p>\n<p>All this is taking place even before InSight\u2019s takeoff: While engineers practice on the replica in JPL\u2019s testbed, the real lander is being readied for liftoff from Vandenberg Air Force Base in California.
