In the late 1970s, NASA, the Marshall Space Flight Center, and its contractors began focusing on designs for Shuttle-tended space platforms capable of extended periods in space and utilizing a variety of temporarily emplaced payloads. As a result, McDornell Douglas studied the Science and Applications Space Platform (SASP). The emphasis was placed on payloads that did not require a crewman's presence during normal operations. Most of the payloads would occupy one or more Spacelab-like pallets. This artist concept depicts the SASP.

During 1980 and the first half of 1981, the Marshall Space Flight Center conducted studies concerned with a relatively low-cost, near-term, manned space platform to satisfy current user needs, yet capable of evolutionary growth to meet future needs. The Science and Application Manned Space Platform (SAMSP) studies were to serve as a test bed for developing scientific and operational capabilities required by later, more advanced manned platforms while accomplishing early science and operations. This concept illustrates a manned space platform.

KENNEDY SPACE CENTER, FLA. - At Vandenberg Air Force Base in California, Orbital Sciences technicians check the bottom of the DART (Demonstration for Autonomous Rendezvous Technology) flight demonstrator as it is raised off its platform. The spacecraft was developed to prove technologies for locating and maneuvering near an orbiting satellite. Future applications of technologies developed by the DART project will benefit the nation in future space-vehicle systems development requiring in-space assembly, services or other autonomous rendezvous operations. Designed and developed for NASA by Orbital Sciences Corporation in Dulles, Va., the DART spacecraft will be launched on a Pegasus launch vehicle. At about 40,000 feet over the Pacific Ocean, the Pegasus will be released from Orbital’s Stargazer L-1011 aircraft, fire its rocket motors and boost DART into a polar orbit approximately 472 miles by 479 miles. Once in orbit, DART will rendezvous with a target satellite, the Multiple Paths, Beyond-Line-of-Site Communications satellite, also built by Orbital Sciences. DART will then perform several close proximity operations, such as moving toward and away from the satellite using navigation data provided by onboard sensors. DART is scheduled for launch no earlier than Oct. 18.

Also aboard the free-flying research platform will be the Middle Atmosphere High Resolution Spectrograph Instrument (MAHRSI). Other payloads on the 11-day mission include the Manipulator Flight Demonstration (MFD), a Japanese Space Agency-sponsored experiment. Also in Discovery’s payload bay are the Technology Applications and Science-1 (TAS-1) and International Extreme Ultraviolet Hitchhiker-2 (IEH-2) experiments

KENNEDY SPACE CENTER, Fla. -- Blasting through the hazy late morning sky, the Space Shuttle Discovery soars from Launch Pad 39A at 10:41 a.m. EDT Aug. 7 on the 11-day STS-85 mission. Aboard Discovery are Commander Curtis L. Brown, Jr.; Pilot Kent V. Rominger, Payload Commander N. Jan Davis, Mission Specialist Robert L. Curbeam, Jr., Mission Specialist Stephen K. Robinson and Payload Specialist Bjarni V. Tryggvason, a Canadian Space Agency astronaut .

KENNEDY SPACE CENTER, FLA. -- In the late afternoon shadows, space shuttle Atlantis is still poised on the pad after its launch on mission STS-122 was postponed Thursday. It sits atop the mobile launcher platform. Shuttle program managers decided at 9:56 a.m. to postpone the launch because of an issue with a fuel cut-off sensor system inside the external fuel tank. This is one of several systems that protect the shuttle's main engines by triggering their shut down if fuel runs unexpectedly low. During countdown activities this morning, two sensors failed a routine prelaunch check. There are four engine cut-off, or ECO, sensors inside the liquid hydrogen section of the tank, and Launch Commit Criteria require three of the four sensor systems to be functioning properly. The tank's liquid oxygen and liquid hydrogen was drained from the tank, and preparations will begin for a possible launch attempt Friday. NASA's launch rules have a preplanned procedure that states in the case of ECO sensor system failure, engineers need to drain the tank and verify all the sensors are working as they go dry. Atlantis carries the Columbus Laboratory, the European Space Agency's largest contribution to the construction of the space station. When permanently attached to Node 2, the laboratory will carry out experiments in materials science, fluid physics and biosciences, as well as perform a number of technological applications, in a microgravity environment.
