Prince Ernst August of Hanover, (legal name German: "Ernst August Prinz von Hannover Herzog zu Braunschweig und Lüneburg, Königlicher Prinz von Großbritannien und Irland" .
 Named "Ernst August Andreas Philipp Constantin Maximilian Rolf Stephan Ludwig Rudolph", he was born 19 July 1983, the eldest child of Ernst August, Prince of Hanover (head of the ancient House of Welf which once ruled the Kingdom of Hanover), and his former wife Chantal Hochuli.
STS-63 was the first mission of the US/Russian Shuttle-Mir Program, which carried out the first rendezvous of the American Space Shuttle with Russia's space station "Mir".
 Known as the 'Near-Mir' mission, the flight used Space Shuttle "Discovery", which lifted off from launch pad 39B on 3 February 1995 from Kennedy Space Center, Florida.
 A night launch and the 20th mission for "Discovery", it marked the first time a Space Shuttle mission had a female pilot, Eileen Collins, the first EVAs for both a UK born astronaut Michael Foale and a US astronaut of African heritage Bernard A. Harris, Jr. and it also carried out the successful deployment and retrieval of the Spartan-204 platform, along with the scheduled rendezvous and flyaround of "Mir", in preparation for STS-71, the first mission to dock with "Mir".
The B612 Foundation is a private nonprofit foundation headquartered in Menlo Park, California, United States, dedicated to planetary defense against asteroids and other near-Earth object (NEO) impacts.
 It is led mainly by scientists, former astronauts and engineers from the Institute for Advanced Study, Southwest Research Institute, Stanford University, NASA and the space industry.
Mars to stay missions propose astronauts sent to Mars for the first time should intend to stay.
 Unused emergency return vehicles would be recycled into settlement construction as soon as the habitability of Mars becomes evident to the initial pioneers.
 Mars to Stay missions are advocated both to reduce cost and to ensure permanent settlement of Mars.
 Among many notable Mars to Stay advocates, former Apollo astronaut Buzz Aldrin has been particularly outspoken, suggesting in numerous forums "Forget the Moon, Let’s Head to Mars!"
 and, in June 2013, Aldrin promoted a manned mission "to homestead Mars and become a two-planet species."
 In August 2015, Aldrin, in association with the Florida Institute of Technology, presented a "master plan", for NASA consideration, for astronauts, with a "tour of duty of ten years", to colonize Mars before the year 2040.
 The Mars Underground, Mars Homestead Foundation, Mars One, and Mars Artists Community advocacy groups and business organizations have also adopted Mars to Stay policy initiatives.
Prof. Dr. Ernst Willi Messerschmid (born May 21, 1945) is a German physicist and former astronaut.
Spaceflight is a 1985 American documentary miniseries about manned spaceflight, originally broadcast by PBS in four parts.
 It is narrated by Martin Sheen and features interviews with many former astronauts from the Mercury, Gemini, Apollo, and Space Shuttle programs.
 The series is a co-production of WETA-TV and WYES-TV.
 The final episode (Part 4) was redone after the Space Shuttle Challenger disaster (the revision covered the inquiry and the return to flight as well).
Shenzhou 10 () was a manned spaceflight of China's Shenzhou program that was launched on 11 June 2013.
 It was China's fifth manned space mission.
 The mission had a crew of three astronauts: Nie Haisheng, who was mission commander and previously flew on Shenzhou 6; Zhang Xiaoguang, a former PLAAF squadron commander who conducted the rendezvous and docking; and Wang Yaping, the second Chinese female astronaut.
 The Shenzhou spacecraft docked with the Tiangong-1 trial space laboratory module on 13 June, and the astronauts performed physical, technological, and scientific experiments while on board.
 Shenzhou 10 was the final mission to Tiangong 1 in this portion of the Tiangong program.
 On 26 June 2013, after a series of successful docking tests, Shenzhou 10 returned to Earth.
Colin Michael Foale, CBE (born 6 January 1957) is a British-American astrophysicist and former NASA astronaut.
 He is a veteran of six Space Shuttle missions and extended missions on both Mir and the International Space Station.
 He was the first Briton to perform a space walk, and until 17 April 2008, he held the record for most time spent in space by a US citizen: 374 days, 11 hours, 19 minutes.
 He still holds the cumulative-time-in-space record for a UK citizen.
Schloss Wolfsgarten is a former hunting seat of the ruling family of Hesse-Darmstadt, located in the German state of Hessen, approximately 15 kilometers south of Frankfurt am Main.
 The hunting lodge was established between 1722 and 1724 by Landgrave Ernst Ludwig of Hesse-Darmstadt.
 Ernst Ludwig's purpose in establishing Wolfsgarten was to pursue his passion for hunting with dogs which he introduced into Hesse in 1709.
 The original building corresponded to the usual pattern for hunting seats of that era with a rectangular yard around which was grouped housing for gentlemen, the stables for the houses, and kennels for the dogs.
 After Ernst Ludwig's successors abandoned hunting with dogs in 1768, Wolfsgarten was abandoned until the 1830s when the grand ducal family began to restore and expand the property.
 From 1879, Wolfsgarten became a favorite country retreat for Grand Dukes Ludwig IV and his son Ernst Ludwig.
