NASA InSight Lander Successfully Lands on Mars

NASA's InSight lander has landed on Mars, marking the eighth successful landing on the Red Planet. The mission, which began with a launch from California on May 5, traveled 300 million miles over seven months before touching down on November 26 near the equator in Elysium Planitia. The landing was confirmed through signals relayed by two experimental CubeSats, MarCO, which were the first of their kind to travel into deep space.

NASA Administrator Jim Bridenstine called the landing a testament to American and international ingenuity. The InSight team celebrated the successful touchdown, which took place in a six-and-a-half-minute descent through the Martian atmosphere. The lander, which hit the atmosphere at 12,300 mph, autonomously executed dozens of operations flawlessly.

Following the landing, InSight began its surface operations, including deploying its solar arrays to generate power. The process took 16 minutes and was critical for initiating scientific operations. NASA's Odyssey spacecraft will confirm the success of the solar panel deployment, with the signal expected to reach mission control about five-and-a-half hours after landing.

InSight's primary goal is to study the deep interior of Mars to better understand the formation of rocky planets. The lander will deploy its robotic arm and scientific instruments, including the Seismic Experiment for Interior Structure (SEIS) and Heat Flow and Physical Properties Package (HP3), within a few months. The mission is expected to last one Martian year, or about 40 sols, until November 2020.

The MarCO CubeSats, which supported the landing, have completed their mission and opened new possibilities for small spacecraft in planetary exploration. JPL director Michael Watkins called the success a tribute to the teams involved, highlighting the significance of the mission for future Mars exploration and planetary science.
