Envelop contains a 6.25 inch by 3.25 inches card with information on Space Shuttle Discovery printed on one side. This first day cover commemorates STS-26 which was the 26th NASA Space Shuttle mission and the seventh flight of the orbiter Discovery. The mission launched from Kennedy Space Center, Florida, on 29 September 1988, and landed on 3 October. STS-26 was declared the "Return to Flight" mission, being the first mission after the Space Shuttle Challenger disaster of 28 January 1986. It was the first mission since STS-9 to use the original STS numbering system, the first to have all its crew members wear pressure suits for launch and landing since STS-4, and the first mission with bailout capacity since STS-4. STS-26 was also the first U.S. space mission with an all-veteran crew since Apollo 11, with all of its crew members having flown at least one prior mission. The crew were Hauck, Covey, Lounge, Hilmers and Nelson. The envelop has a large mission logo on the left side with these five names at the perimeter. The primary payload for the STS-26 mission, a Tracking and Data Relay Satellite (TDRS), was successfully deployed, and 11 scheduled mid-deck scientific and technological experiments were carried out. During STS-26, Discovery became the first spacecraft to fly in space equipped with a VCU (Voice Control Unit), a computer capable of recognizing and responding to human speech. Discovery suffered damage to its thermal protection tiles in the underwing area. Post-flight analysis showed that the impact of a 12-inch long piece of insulation during ascent was the culprit Martha Black sent this to Mr. and Mrs. John Adamsky. Ink notation on back indicates it was sent by Ms. Black. M. M. Black is listed on the staff of the Presidential Commission on the Space Shuttle Challenger Accident as the Personal Assistant to the Vice Chairman and the Executive Director. She was assigned from the Office of Management and Budget. Neil Armstrong was the Vice Chairman. Dr. Alton G. Keel Jr. was the Executive Director and was assigned from the White House staff. One of the addressees, Ms. Megan Adamsky, led an adventurous life. After graduating from the University of New Mexico, she taught school in Los Alamos and Seattle. She then moved to an oil camp in the jungles of Venezuela, where she was responsible for educating the children of the oil workers. There she met John Adamsky, who remained her loving husband until his death in 1994. His work took them to many parts of the globe from Italy to the Far East. Space Shuttle Discovery (Orbiter Vehicle Designation: OV-103) is one of the orbiters from NASA's Space Shuttle program and the third of five fully operational orbiters to be built. Its first mission, STS-41-D, flew from August 30 to September 5, 1984. Over 27 years of service it launched and landed 39 times, aggregating more spaceflights than any other spacecraft to date. The Space Shuttle launch vehicle has three main components: the Space Shuttle orbiter, a single-use central fuel tank, and two reusable solid rocket boosters. Nearly 25,000 heat-resistant tiles cover the orbiter to protect it from high temperatures on re-entry. The origin of the debris was the forward field joint on the right-hand SRB. Discovery suffered damage to its thermal protection tiles in the underwing area. The damage was such that, during re-entry, the thermal protection tile eroded almost completely. A similar chain of events ultimately led to the loss of Columbia fifteen years later. Discovery became the third operational orbiter to enter service, preceded by Columbia and Challenger. It embarked on its final mission, STS-133, on February 24, 2011 and touched down for the last time at Kennedy Space Center on March 9, having spent a cumulative total of nearly a full year in space. Discovery performed both research and International Space Station (ISS) assembly missions, and also carried the Hubble Space Telescope into orbit. Discovery was the first operational.
