The `once upon a time' science fiction concept of a space elevator has been envisioned and studied as a real mass transportation system in the latter part of the 21st century. David Smitherman of NASA's Marshall Space Flight Center's Advanced Projects Office has compiled plans for such an elevator. The space elevator concept is a structure extending from the surface of the Earth to geostationary Earth orbit (GEO) at 35,786 km in altitude. The tower would be approximately 50 km tall with a cable tethered to the top. Its center mass would be at GEO such that the entire structure orbits the Earth in sync with the Earth's rotation maintaining a stationary position over its base attachment at the equator. Electromagnetic vehicles traveling along the cable could serve as a mass transportation system for transporting people, payloads, and power between space and Earth. This illustration by artist Pat Rawling shows the concept of a space elevator as viewed from the geostationary transfer station looking down the length of the elevator towards the Earth.

S86-25375 (1986) --- (Artist's concept of possible exploration programs.) On Phobos, the innermost moon of Mars and likely location for extraterrestrial resources, a mobile propellant-production plant lumbers across the irregular surface. Using a nuclear reactor the large tower melts into the surface, generating steam which is converted into liquid hydrogen and liquid oxygen.

STS-26 Discovery, Orbiter Vehicle (OV) 103, artwork depicts tracking and data relay satellite C (TDRS-C) deployment. OV-103 orbits above Earth in bottom-to-sun attitude, moments after TDRS-C's release into space. TDRS-C is seen just below open payload bay (PLB). Artwork was done by Pat Rawlings of Eagle Engineering.

S84-36158 (June 1984) --- The STS-41G Challenger mission insignia focuses on its seven crew members (first to exceed six), the United States flag and the Unity symbol known as the astronaut pin. The pin design in center shows a trio of trajectories merging in infinite space, capped by a bright shining star and encircled by an elliptical wreath denoting orbital flight. Crew members for the (originally-scheduled 17th STS) mission include astronauts Robert L. Crippen and Jon A. McBride, commander and pilot, respectively, whose surnames flank those of the NASA mission specialists - astronauts Kathryn D. Sullivan, David C. Leestma and Sally K. Ride. Paul Scully-Power, a United States Navy oceanographer, and Marc Garneau, a Canadian, join the crew as payload specialists. The artwork was done for NASA by Patrick Rawlings. The NASA insignia design for space shuttle flights is reserved for use by the astronauts and for other official use as the NASA Administrator may authorize. Public availability has been approved only in the forms of illustrations by the various news media. When and if there is any change in this policy, which is not anticipated, the change will be publicly announced. Photo credit: NASA
