SAN DIEGO, Calif. – The Orion boilerplate test vehicle was offloaded from the USS San Diego at the U.S. Naval Base San Diego in California. Orion was transported in the ship’s well deck about 100 miles offshore for an underway recovery test. NASA and the U.S. Navy conducted tests to prepare for recovery of the Orion crew module, forward bay cover and parachutes on its return from a deep space mission. The underway recovery test allowed the teams to demonstrate and evaluate the recovery processes, procedures, hardware and personnel in open waters. During the testing, the tether lines were unable to support the tension caused by crew module motion that was driven by wave turbulence in the well deck of the ship. NASA and the U.S. Navy are reviewing the testing data collected to evaluate the next steps. The Ground Systems Development and Operations Program was conducting the recovery tests. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. The first unpiloted test flight of the Orion is scheduled to launch in 2014 atop a Delta IV rocket and in 2017 on NASA’s Space Launch System rocket.

A worker uses a forklift to unload the Robotic Refueling Mission-3 (RRM3) payload from a truck at the Payload Hazardous Servicing Facility on Oct. 3, 2018, at NASA's Kennedy Space Center in Florida. The payload will be carried to the International Space Station on SpaceX's 16th Commercial Resupply Services mission. RRM3 demonstrates the transfer of xenon gas and liquid methane in microgravity, and advances technologies for storing and manipulating these cryogenic fuels robotically. RRM3 also supports development of technology for the Restore-L mission, a robotic spacecraft equipped to service satellites in-orbit.

KENNEDY SPACE CENTER, FLA. - A Hyster forklift in the Orbiter Processing Facility moves the body flap toward the aft of the orbiter Discovery.
