Neptune, Voyager 2 image
Neptune. Neptune is a gas giant, composed mostly of hydrogen and helium with some methane. Seen at centre is the Great Dark Spot, thought to be a hole in the methane cloud deck of Neptune, accompanied by bright, white, high-altitude clouds. This image was reconstructed from two images (one through a green filter and one through an orange filter), taken by the narrow-angle camera aboard the Voyager 2 spacecraft in August 1989.

Apollo lunar rover, artwork. Two Apollo astronauts in a lunar rover, exploring on the Moon. Their lunar landing module is at upper left. The lunar rovers were used on the last three Apollo missions (Apollo 15, 16 and 17). Each rover was used three times, once for each day of the three-day stays on the lunar surface. They were driven between 12 and 20 kilometres on each excursion, with the excursions lasting between three and four-and-a-half hours. The route taken was planned to allow the astronauts to walk back to the landing module if the rover failed. The rovers had a video camera and high-gain antenna to transmit images back to Earth.

McDonnell Douglas YC-15A 72-1876
McDonnell Douglas YC-15A 72-1876 (msn CX002), the second prototype, at the 1976 SBAC Farnborough Air Show. First flown in December 1975 , 1876 was returned to McDonnell Douglas in late-1976 for modifications, including fitting a Pratt & Whitney JT8D-209 engine in the left outer nacelle, flying again on 4 March 1977 after the modifications, but was retired to AMARC as CX002 on 30 August 1979. 1876 was still on the AMARC inventory on 15 January 2008, but had been broken up and scrapped by March 2012. Date: 1976
