Humanity may be years away from setting foot on #Mars, but the Red Planet is turning into something of a monument park for our species all the same. Rovers and landers—some still operating, some having completed their functional life—dot the surface, and orbiters cross the skies overhead. On Nov. 26 at 2:47 p.m. EST, the Mars InSight lander joined the growing fleet, and it will be less concerned with what happens on or above Mars and more with what goes on within it. In this handout photograph, Julie Wertz-Chen, an Entry, Descent and Landing systems engineer, left, and systems engineer Aline Zimmer react after receiving confirmation inside the Mission Support Area at @nasajpl in Pasadena. Launched last May on a 270-million mile arcing trajectory, the new addition weighs just 1,530 lbs., including fuel and the protective aeroshell designed to help it survive the plunge through Mars’s tenuous atmosphere. It measures just 33 to 43 inches tall, depending on how far its three spindly legs compress after landing. The main body is just 5 ft. wide, without its #solar panels deployed. But @NASA engineers have packed a lot of #science into that comparatively small package, writes @TIME Magazine's Jeffrey Kluger: it is equipped with a seismometer that relies on half a dozen different sensors to measure planetary perturbations in a range of frequencies; a movement and wobble sensor that detects anomalies in Mars’s rotation; and, most significantly, a deep thermal probe, which a robotic arm will hammer up to 16 ft. into the surface of the planet, far deeper than any spacecraft has dug before. As with all Mars missions, the landing was the most harrowing part, with the spacecraft relying on aerobraking, a parachute system and #rocket engines to touch down softly. #InSight is expected to work for at least two years, after which it too will go silent. Its time on Mars will be comparatively fleeting, but the knowledge it sends home about Earth’s closest planetary kin will endure. Read more on TIME.com.
