Solstice Canyon was an important site of early pioneering space research. Technology laboratories, Inc., a subsidiary of Thompson-Ramo-Wooldridge (TRW), rented 10 acres from the Roberts Family from 1961-1973. The site was used to test satellite equipment for space missions, including the Pioneer 12.
Solstice Canyon was one of only three places in the world chosen to conduct such tests, due to the lack of man-made or natural disturbances. At the TRW overlook you can see the foundations of the TRW buildings, all that remain after the Corral Fire.
Today, Solstice Canyon still serves as a haven from city life. The Santa Monica Mountains Conservancy first opened Solstice Canyon as a public park in 1988. It is now managed by the National Park Service.
