Mars 2020 Rover Tests Descent-Stage Separation

In this picture from Sept. 28, 2019, engineers and technicians working on the assembly and testing of the Mars 2020 spacecraft look on as a crane lifts the rocket-powered descent stage away from the rover.


NASA's Push to Save the Mars InSight Lander's Heat Probe

NASA's Push to Save the Mars InSight Lander's Heat Probe

NASA's InSight lander, which is on a mission to explore the deep interior of Mars, positioned its robotic arm this past weekend to assist the spacecraft's self-hammering heat probe. Known as "the mole," the probe has been unable to dig more than about 14 inches (35 centimeters) since it began burying itself into the ground on Feb. 28, 2019.

Mars 2020 Rover Spun Up For Center Of Gravity Determination

Mars 2020 Rover Spun Up For Center Of Gravity Determination

Engineers took NASA's Mars 2020 for a spin on Aug. 29, 2019. The 2,300-pound (1,040-kilogram) Martian vehicle was rotated clockwise and counterclockwise at about 1 revolution per minute on what is called a spin table in the clean room of the Spacecraft Assembly Facility at NASA's Jet Propulsion Laboratory in Pasadena, California.
