McDonnell Douglas Concept of Orbiting Power System With giant arrays of solar electric cells spread like wings, a space power system that provides electricity for long-term Space Shuttle missions and orbiting payloads is depicted in an artist’s rendering. The McDonnell Douglas Astronautics Company, Huntington Beach, California, has been selected by the NASA Marshall Space Flight Center for a one-year, $1 million competitive design definition study for the 25- kilowatt power system. It would be used during the mid-1980s and beyond, to support many space programs with requirements for power beyond the limits of the Shuttle. A Shuttle Orbiter vehicle is seen in the distance; the large radar dish and other pay loads attached to the power system’s center module are installed in pay load pallets flown up in the Orbiter cargo bay and left in orbit for extended periods.
