Orbiting Vehicle 1-7 (also known as OV1-7), launched on 14 July 1966, was the sixth satellite launched in the OV1 series of the United States Air Force's Orbiting Vehicle program. OV1-7 was a sky science satellite, designed to return data on charged particles in orbit as well as measurements of solar X-rays and nightglow. Co-launched with OV1-8, the satellite was lost when it failed to detach from its launch rocket.

Orbiting Vehicle 1-8 (also known as OV1-8, OV1-8P, PasComSat,  and Gridsphere), launched on 14 July 1966, was the seventh satellite launched (fourth successfully) in the OV1 series of the United States Air Force's Orbiting Vehicle program. OV1-8 was designed to test the passive communications utility of an aluminum grid sphere versus a balloon satellite (e.g. NASA's Project Echo).
