When astronauts return to Earth from destinations beyond the Moon in NASA’s Orion spacecraft and splashdown in the Pacific Ocean, they’ll still need to safely get out of the spacecraft and back on dry land. Using the waters off the coast of Galveston, Texas, a NASA and Department of Defense team test Orion exit procedures in a variety of scenarios on July 11, 2017.

This September 1972 photograph shows the internal configuration of Skylab's Multiple Docking Adapter (MDA) flight article as it appeared during the Crew Compartment and Function Review at the Martin-Marietta Corporation's Space Center facility in Denver, Colorado. Designed and manufactured by the Marshall Space Flight Center, the MDA housed a number of experiment control and stowage units and provided a docking port for the Apollo Command Module.

This August 1971 interior photograph of Skylab's Multiple Docking Adapter (MDA) flight article, undergoing outfitting at the Martin-Marietta Corporation's Space Center facility in Denver, Colorado, shows the forward cone area and docking tunnel (center) that attached to the Apollo Command Module. Designed and manufactured by the Marshall Space Flight Center, the MDA housed the control units for the Apollo Telescope Mount, Earth Resources Experiment Package, and Zero-Gravity Materials Processing Facility and provided a docking port for the Apollo Command Module.

This interior photograph of Skylab's multiple docking adapter (MDA) flight article, then undergoing outfitting at the Martin Marietta Corporation's Space Center facility in Denver, Colorado, shows the forward cone area and docking turnel (center) that attached to the Apollo Command Module. Designed and manufactured by the Marshall Space Flight Center, the MDA housed the control units for the Apollo Telescope Mount (ATM), Earth Resources Experiment Package (EREP), and Zero-Gravity Materials Processing Facility and provided a docking port for the Apollo Command Module.

This December 1971 photograph shows the internal configuration of Skylab's Multiple Docking Adapter (MDA) flight article (forward view) as it appeared during the crew compartment and function review at the Martin-Marietta Corporation's Space Center Facility in Denver, Colorado. Designed and manufactured by the Marshall Space Flight Center, the MDA housed a number of experiment control and stowage units as well as providing a docking port for the Apollo Command module.

Workmen at the Martin Marietta Corporation's Space Center facility in Denver, Colorado, lower the Skylab Multiple Docking Adapter (MDA) flight article into the horizontal rotation fixture in preparation for the crew compartment and function review. Designed and manufactured by the Marshall Space Flight Center and outfitted by Martin Marietta, the MDA housed a number of experiment control and stowage units and provided a docking port for the Apollo Command Module.

Workmen at the Martin Marietta Corporation's Space Center in Denver, Colorado, position Skylab's Multiple Docking Adapter (MDA) flight article in the horizontal transportation fixture. Designed and manufactured by the Marshall Space Flight Center and outfitted by Martin Marietta, the MDA housed the control units for the Apollo Telescope Mount (ATM), Earth Resources Experiment Package (EREP), and Zero-Gravity Materials Processing Facility and provided a docking port for the Apollo Command Module.

At Marshall Space Flight Center, Skylab's Multiple Docking Adapter (MDA) flight article undergoes center-of-gravity testing. Developed and fabricated by MSFC, the MDA housed the control units for the Apollo Telescope Mount (ATM), Earth Resources Experiment Package (EREP), and the Zero-Gravity Material Processing Facility and provided a docking port for the Apollo Command Module.
