NASA Begins Testing Robotics to Bring First Samples Back From Mars Getting those samples into terrestrial labs would take a decade and involve European partners and multiple NASA centers. ESA (the European Space Agency) is developing a rover for the effort, with engineers at NASA’s Glenn Research Center in Cleveland, Ohio, designing its wheels. The rover would transfer samples to a lander, being developed at NASA’s Jet Propulsion Laboratory in Southern California, that would use a robotic arm (developed by ESA) to pack the samples into a small rocket, called a Mars Ascent Vehicle, being designed by NASA’s Marshall Space Flight Center in Huntsville, Alabama. The rocket would launch from the lander to deliver the sample capsule to an ESA spacecraft orbiting Mars. Inside the orbiter, the capsule would be prepared for delivery to Earth by hardware that a team led by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, is developing. This preparation would include sealing the sample capsule within a clean container to trap any Martian material inside, sterilizing the seal, and placing the sealed container into an Earth-entry capsule before the return trip to Earth.
