Associated space launch
Nimbus 2, the second in a series of second-generation meteorological research-and-development satellites, added an additional medium-resolution infrared radiometer (MRIR) compared to Nimbus 1.
NIMBUS 2 was lifted into orbit during the mission ‘Thor SLV-2A Agena B | Nimbus 2’, on board a Thor SLV-2A Agena B space rocket.
The launch took place on May 15, 1966, 7:55 a.m. from Space Launch Complex 2E.
