Mission Details

Vela 5A/5B

Vela was the name of a group of satellites developed as the Vela Hotel element of Project Vela by the United States to detect nuclear detonations to monitor compliance with the 1963 Partial Test Ban Treaty by the Soviet Union.

Payloads: 2
Total Mass: 518.0 kg
Highly Elliptical Orbit

OV5-5

The satellite had an octagonal configuration, was spin-stabilized, and was placed in a moderately elliptical earth orbit (eccentricity - 0.670) by a Titan 3C on May 25, 1969. The purpose of the satellite was to monitor x-ray, electron, and proton radiation associated with solar activity in order to develop data handling techniques in near real-time for use by the Air Weather Service Forecast Center in forecasting solar flares.

Payloads: 1
Total Mass: 11.0 kg

OV5-6

The satellite had an octagonal configuration, was spin-stabilized, and was placed in a moderately elliptical earth orbit (eccentricity - 0.670) by a Titan 3C on May 25, 1969. The purpose of the satellite was to monitor x-ray, electron, and proton radiation associated with solar activity in order to develop data handling techniques in near real-time for use by the Air Weather Service Forecast Center in forecasting solar flares.

Payloads: 1
Total Mass: 23.0 kg

OV5-9

The purpose of this octahedral satellite was to monitor solar activity by measuring solar particle and x-ray fluxes. The experiments were designed to investigate physical processes occurring at the magnetopause and the mechanisms of particle acceleration. This spacecraft malfunctioned from the first day of launch due to commutator and power system problems. A very limited amount of useful data was obtained. The satellite became inoperable as of October 1972.
