Resembling a vintage car engine's air filter, the sampler head of TAGSAM can hold up to 4.4 pounds of material.

When Lockheed Martin engineers tested the deployment of OSIRIS-REx's Touch and Go Sample Acquisition Mechanism (TAGSAM), they used a helium balloon to simulate the microgravity environment the arm would experience in space.

On February 11, 2016, OSIRIS-REx underwent environmental testing in a Lockheed Martin thermal vacuum chamber. Launched nearly seven months later on September 8, 2016, the spacecraft is now more than 200 million miles from Earth—and poised to touch the surface of another world.

Engineers deploy the solar arrays on NASA's InSight lander inside a clean room at Lockheed Martin Space Systems in Denver. This is how the spacecraft will look once it lands on the surface of Mars.

Engineers work on NASA's InSight spacecraft in a clean room in 2015, during the mission's assembly and testing phase.

The back shell of NASA's InSight spacecraft gets lowered onto the mission's lander, which is folded up for launch. The back shell and a heat shield together form the aeroshell, which will protect the lander as the spacecraft plunges into the Martian atmosphere.
