Launch vehicle. | ATLAS Agena D rocket. |
Launch date. | 1965. |
Launch site. | Vandenberg Air Force Base. |
Ceased operations. | It had shut down after 43 days due to a non-nuclear malfunction caused by a broken on-board (carried inside) voltage regulator within the spacecraft. |
Owner(s). | U.S. Atomic Energy Commission. |
Major contractor(s). | Atomics International had primary responsibility and Sandia National Laboratories. |
Is it still in orbit. | Yes, until circa ~5,965. Some minor bits stared coming off since the November of 1979 after a collision and radiation is leaking out. The main parts and the reactor core are still safely in orbit. |

History[]
The plan was tn the 1950s and early 1960s. The Systems Nuclear Auxiliary Power Program (SNAP) reactor was developed i as part of the SNAPSHOT program overseen by the U.S. Atomic Energy Commission.
Idaho National Laboratory conducted 3 pre-launch destructive tests in Test Area North, including the SNAPTRAN-3 destructive experiment, on April 1, 1964. The test simulated a rocket crash into the ocean, radiating part of the Idaho desert in a deliberate fire ball.
There were other atomic satellites, including the Soviet RORSAT and Safe Affordable Fission Engine test satellites.
The plan was to create an endless or near endless power-supply for space vessels and satellites, since solar panels only worked in star-light and batteries would eventually run out.
