The Jet Propulsion Laboratory team in Pasadena is responsible for designing and building the unmanned spacecraft and supply missions that become critical to Mark Watney's survival on Mars. Led by JPL Director Bruce Ng, the team is tasked with the seemingly impossible challenge of building and launching a resupply probe on an accelerated timeline - compressing years of engineering work into months. The JPL engineers work under extraordinary pressure, improvising solutions and cutting corners that would normally be unthinkable, all while knowing that any failure means Watney dies. Their resourcefulness and willingness to push beyond established limits mirrors Watney's own improvisation on the Martian surface.
