Space Shuttle

The Space Shuttle was a partially reusable low Earth orbital spacecraft system operated by the U.S. National Aeronautics and Space Administration (NASA), as part of the Space Shuttle program. Its official program name was Space Transportation System (STS), taken from a 1969 plan for a system of reusable spacecraft of which it was the only item funded for development. The first of four orbital test flights occurred in 1981, leading to operational flights beginning in 1982. They were used on a total of 135 missions from 1981 to 2011, launched from the Kennedy Space Center (KSC) in Florida. Operational missions launched numerous satellites, interplanetary probes, and the Hubble Space Telescope (HST); conducted science experiments in orbit; and participated in construction and servicing of the International Space Station. The Shuttle fleet's total mission time was 1322 days, 19 hours, 21 minutes and 23 seconds.

Shuttle components included the Orbiter Vehicle (OV), a pair of recoverable solid rocket boosters (SRBs), and the expendable external tank (ET) containing liquid hydrogen and liquid oxygen. The Shuttle was launched vertically, like a conventional rocket, with the two SRBs operating in parallel with the OV's three main engines, which were fueled from the ET. The SRBs were jettisoned before the vehicle reached orbit, and the ET was jettisoned just before orbit insertion, which used the orbiter's two Orbital Maneuvering System (OMS) engines. At the conclusion of the mission, the orbiter fired its OMS to de-orbit and re-enter the atmosphere. The orbiter then glided as a spaceplane to a runway landing, usually at the Shuttle Landing Facility of KSC or Rogers Dry Lake in Edwards Air Force Base, California. After landing at Edwards, the orbiter was flown back to the KSC on the Shuttle Carrier Aircraft, a specially modified Boeing 747.

Mission Specialist

A Mission Specialist (MS) is a position held by certain NASA astronauts. A Mission Specialist is assigned to a limited field of the mission, such as for medical experiments or technical quests.

Other functions on board were Pilot, Flight Engineer and Mission Commander. Some Space Shuttle missions included Payload Specialists in addition to Mission Specialists. While a Payload Specialist was selected for a single specific mission, a Mission Specialist was selected as an astronaut first, and then assigned to a mission.

Mission Specialist is abbreviated by NASA as MS.

Byron K. Lichtenberg

Byron Kurt Lichtenberg, Sc. D. (born February 19, 1948) is an American engineer and fighter pilot who flew aboard two NASA Space Shuttle missions as a Payload Specialist. In 1983, he and Ulf Merbold became the first Payload Specialists to fly on the shuttle.

Personal

Career

From 1978 to 1984 he was a researcher for the Massachusetts Institute of Technology (MIT)/Canadian Vestibular experiments on Spacelab 1, Spacelab D-1, Spacelab SLS-1 and SLS-2, and a co-principal investigator for the Mental Workload and Performance experiment flown on IML-1 to assess human-computer workstation characteristics for the Space Station.

Payload Specialist

A Payload Specialist (PS) is an individual selected and trained by commercial or research organizations for flights of a specific payload on a NASA Space Shuttle mission. People assigned as Payload Specialists included individuals selected by the research community, a company or consortium flying a commercial payload aboard the spacecraft, and non-NASA astronauts designated by international partners.

The term refers to both the individual and to the position on the Shuttle crew.

History

Payload Specialists were generally selected for a single specific mission and were chosen outside the standard NASA astronaut selection process. They were not required to be United States citizens, but had to be approved by NASA and undergo rigorous training. In contrast, a Space Shuttle Mission Specialist was selected as a NASA astronaut candidate first and then assigned to a mission.

Payload Specialists on early missions were technical experts to accompany specific payloads such as a commercial or scientific satellite. On Spacelab and other missions with science components, payload specialists were scientists with expertise in specific experiments. The term also applied to representatives from partner nations who were given the opportunity of a first flight on board of the Space Shuttle (such as Saudi Arabia and Mexico), and to Congressmen and the Teacher in Space program.

ABC News

ABC News is the news division of the American Broadcasting Company (ABC), owned by the Disney Media Networks division of the Walt Disney Company. Its flagship program is the daily evening newscast ABC World News Tonight; other programs include morning news-talk show Good Morning America, newsmagazine series Nightline, Primetime and 20/20, and Sunday morning political affairs program This Week with George Stephanopoulos.

History

ABC began news broadcasts early in its independent existence as a radio network after the Federal Communications Commission (FCC) ordered NBC to spin off the former NBC Blue Network into an independent company in 1943. The split (which NBC conducted voluntarily in the event that its appeal to have the ruling overturned was denied) was enforced to expand competition in radio broadcasting in the United States as the industry had only a few companies such as NBC and CBS that dominated the radio market, and in particular, was intended to prevent the limited competition from dominating news and political broadcasting and projecting narrow points-of-view. Television broadcasting was suspended however, during World War II.
