Launched on July 13, 1994, the 198-kg DARPASAT demonstrated the possibility of placing in orbit a lightweight, low-cost payload for enhancing operational defense and warfighting capabilities. The primary performer, Ball Aerospace, oversaw the design, fabrication, integration, and testing of the spacecraft bus, which carried two government-supplied payloads. With frugal management of battery use and thermal loads, DARPASAT surpassed its mission goal of a three-year lifetime by lasting for eight years.

The goal of the Global Low Orbiting Message Relay (GLOMR) satellite (aka CHEAPSAT) program was to demonstrate the feasibility of building a two-way, digital data communication satellite capable of performing important military missions for less than a million dollars in under a year. The broader objective was to demonstrate low-cost satellite construction technology that could pave the way for future satellites performing diverse missions.

Under DARPA sponsorship, Defense Systems, Inc. (DSI) designed and developed GLOMR. The spacecraft was placed into orbit from a getaway special canister (or GASCAN) aboard the Space Shuttle Challenger (Mission 61-A, Spacelab D-1) on October 30, 1985, and operated successfully on orbit for over 14 months, before it fell back into the Earth’s atmosphere.

A series of tests, including the use of a portable access terminal at DARPA, were conducted between Washington, D.C., and Santa Barbara, California, demonstrating two-way, cross-country communications via GLOMR. DARPA assisted in transitioning the capability of, and lessons learned from, the GLOMR program to the Defense Department (DoD) and other government agencies.

The GLOMR program demonstrated the feasibility of low-cost satellites. This spacecraft served as a model for many DoD and non-DoD uses, including communications, tracking of beacons, remote- sensor readout, and classified applications.

DARPA initiated a Small Standard Launch Vehicle (SSLV) program that led to the Taurus, a launch vehicle designed to supply the Department of Defense with quick-response, low-cost launch of tactical satellites from ground facilities. The initial DARPA model was first test-launched in 1989 and first used operationally in 1994. The prime contractor subsequently offered the vehicle in four versions.

The goal of the DARPA Launch Challenge is to demonstrate responsive and flexible space launch capabilities from the burgeoning industry of small launch providers. For nearly 60 years, the nation’s space architecture has been built around exquisite systems that are launched by large, expensive boosters. The development cycle with the systems is tedious, with a process driven by a desire to reduce risk, rather than deliver timely capabilities.

Inserting new capabilities into a satellite is no simple task. Doing so as that satellite hurdles through space 22,000 miles above the Earth is a bit more challenging still. DARPA’s Phoenix program, which hopes to repurpose retired satellites while they remain in orbit, seeks to fundamentally change how space systems could be designed here on earth and then sustained once in space.
