Solar Probe Plus will plunge directly into the sun’s atmosphere at approximately 4 million miles from the sun’s surface into a region that no other spacecraft has ever encountered. The spacecraft folds its solar panels into the shadows of its protective solar shade, leaving just enough of the specially-angled panels in sunlight to provide power closer to the Sun. JHU/APL/NASA

The STS-29 Space Shuttle Discovery mission approaches for a landing at NASA's then Ames-Dryden Flight Research Facility, at Edwards Air Force Base, in California in March 1989. NASA
The concept of using a mothership for the space shuttle ferry mission between California and Florida was proposed at Dryden. The Boeing 747 Shuttle Carrier Aircraft evolved from recommendations made by center engineers. The SCA was subsequently used to launch the prototype Enterprise and now serves as one of two ferry vehicles when weather requires an orbiter to land at Edwards and return to Kennedy. In 1977, Dryden hosted approach and landing tests made with the prototype orbiter Enterprise to evaluate the glide and landing characteristics of the 100-ton vehicles. NASA

This picture of Venus was captured by the Mariner 10 spacecraft during its approach to the planet in early 1974. Taken with the spacecraft's imaging system using an ultraviolet filter, the picture has been color enhanced to simulate Venus's natural color as the human eye would see it. NASA/JPL-Caltech
This spaceborne radar image covers a rugged mountainous area of southeast Tibet, 50 miles east of the city of Lhasa. In the lower right corner is a wide valley of the Lhasa River, which is populated with Tibetan farmers and yak herders, and includes the village of Menba. NASA
Ham tries out his combination couch and life support system in preparation for his flight in Mercury Redstone-2 in 1961. The couch is plugged into the circuit that normally would supply the astronaut's full pressure suit. The MR-2 flight was one in a series of flights that led to the manned orbital flights of NASA's Project Mercury program. NASA
