| 説明 | This $9.35 Bald Eagle postage stamp was issued by America on 12 August 1983 (= Scott Catalogue # 1909). The unusual high denomination paid the rate for next-day express mail packages.The stamp is affixed to a cover that's been in space. About 260,000 stamped covers were aboard the Space Shuttle Challenger during its August-September 1983 space flight (this mission was nicknamed "STS-8"). Cancellations indicate the dates of launch and return to Earth.America's Space Shuttle Program lasted from the 1970s to the 2010s, when politicians shut it down. Space shuttles were re-usable spacecrafts. Six were built: Enterprise, Columbia, Challenger, Discovery, Atlantis, and Endeavour. The latter five flew into space.---------------------------Published info. in booklet:[Note: the undefined acronym "STS" means Space Transportation System; the undefined acronym "INSAT-1B" means Indian National Satellite # 1B.]THE STS-8 FLIGHT COVERUSPS/NASAThrough the cooperative efforts of the United States Postal Service and the National Aeronautics and Space Administration, this special event cover (envelope) was developed and carried aboard STS-8, NASA's official designation for the eighth Space Shuttle fliht. This cover is unique because it is the first to record the flight into space with originating and returning postal cancellations. The cover's front cachet is a reproduction of NASA's official "patch" design for STS-8, and the cachet on the reverse side depicts NASA's 25th anniversary logo. The stamp affixed is also noteworth because it was issued at the Kennedy Space Center on August 12, 1983. The August 14, 1983 cancellation date on the front of the cover indicates the day STS-8 was scheduled to be launched with its cargo of covers, including this one. NASA's 25th anniversary logo is part of the cancellation design on the front of the cover. The circular postmark cancellation on the reverse side of the cover indicates the place and date the shuttle returned to Earth.Members of the crew were Richard H. Truly, commander, Daniel C. Brandenstein, Dale A. Gardner, Guion S. Bluford, and William B. Thornton.During the flight, the INSAT-1B communications satellite was put into orbit and several important experiments were conducted. One of these included using an electrical field to separate molecules in liquid suspension, for possible pharmaceutical applications. Also, the 50 foot-long mechanical arm in the cargo payload area was tested in preparation for retrieving the Solar Observatory Satellite, which was launched several years ago to monitor the Sun. On a later shuttle flight, NASA plans to have astronauts take the ailing observatory out of its orbit, make repairs, and then relaunch it.---------------------------Published info. in booklet:The STS-8 Mission(All figures are approximate)Orbit Velocity: 17,400 miles per hourNumber of orbits: 81Altitutde: 184 statute miles above Earth's surfaceTotal distance traveled: 21,000,000Maximum acceleration: 3.0 g'sMaximum deceleration: 1.6 g'sEquivalent horsepower at liftoff: 132,000,000---------------------------Info.:en.wikipedia.org/wiki/Space_Shuttle_programanden.wikipedia.org/wiki/STS-8 |
