A truck arrives at NASA's Jet Propulsion Laboratory in Southern California on June 3, 2024, to deliver the Medium Articulating Transportation System (MATS), which will be used during the construction and transportation of components for NASA's Near-Earth Object Surveyor mission. Originating at the aerospace company Beyond Gravity in Vienna, Austria, the MATS traveled via ship through the Panama Canal to Port Hueneme, California, before arriving by road at JPL.

Construction has begun on NEO Surveyor's instrument enclosure in the High Bay 1 clean room at JPL's Spacecraft Assembly Facility. When the enclosure is complete later this year, it will be moved inside the MATS to NASA's Johnson Space Center in Houston for environmental testing. The MATS is a transportable clean room with its own filtration and climate control systems that keep the spacecraft and components clean, stable, and safe while being moved between facilities.

Figure A shows the MATS being lowered to the ground in front of the high bay's airlock after being lifted by a crane from the truck's flatbed trailer. The MATS was then rolled into the airlock to be cleaned before entering the high bay clean room.

NEO Surveyor's instrument enclosure contains the spacecraft's telescope, mirrors, and infrared sensors that will be used to detect, track, and characterize the most hazardous near-Earth objects. BAE Systems, Space Dynamics Laboratory, and Teledyne are among the aerospace and engineering companies contracted to build the spacecraft and its instrumentation. The Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder will support operations, and IPAC at Caltech in Pasadena, California, is responsible for processing survey data and producing the mission's data products. JPL manages the project; Caltech manages JPL for NASA.

Launching no earlier than 2027, NEO Surveyor supports the objectives of NASA's Planetary Defense Coordination Office (PDCO) at NASA Headquarters in Washington. The NASA Authorization Act of 2005 directed NASA to discover and characterize at least 90% of the near-Earth objects more than 140 meters (460 feet) across that come within 30 million miles (48 million kilometers) of our planet's orbit. Objects of this size can cause significant regional damage, or worse, should they impact the Earth.
