One of the world’s earliest and most well-known spy satellite programs, the now declassified Corona photo-reconnaissance program was jointly funded by DARPA and the Central Intelligence Agency. Withstanding a series of initial failures, the program scored its first success in August 1960 when a canister of film dropped back through the atmosphere was successfully recovered, delivering a trove of intelligence photos taken over Soviet territory. The Corona program continued to acquire crucial Cold War intelligence until the mission ended in 1972.

On October 4, 1957, the Soviet Union (USSR) launched the first satellite ever, triggering events that led to creation of the Advanced Research Projects Agency (ARPA) on February 7, 1958. Although it was well known that both the USSR and the United States were working on satellites for the international scientific collaboration known as the International Geophysical Year (an 18-month “year” from July 1, 1957, to December 31, 1958 and designed to coincide with a peak phase of the solar cycle), many in the United States never fathomed that the USSR would be the first into space. “Now, somehow, in some way, the sky seemed almost alien,” then-Senate Majority Leader Lyndon B. Johnson recalled feeling on that night, adding that he remembered “the profound shock of realizing that it might be possible for another nation to achieve technological superiority over this great country of ours.” Ever since its establishment on February 7, 1958, ARPA—which later added the D for defense at the front of its name—has been striving to keep that technological superiority in the hands of the United States.

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.
