| Title |
STS-39 Critical Ionization Velocity (CIV) gas release from OV-103 payload bay |
| Description |
A plume of nitrous oxide gas is released from a compressed gas canister mounted on the increased capacity adaptive payload carrier 1 (ICAPC-1) on the forward port side of Discovery's, Orbiter Vehicle (OV) 103's, payload bay (PLB). The gas release is part of the Critical Ionization Velocity (CIV) experiment conducted during STS-39. The Shuttle Pallet Satellite II (SPAS-II) "parked" about two kilometers (km) away, is taking infrared, visible, and ultraviolet radiometric spatial, spectral, and temporal measurements of the gas plumes. Surrounding the CIV ICAPC-1 are: the ICAPC-2 payload support subsystem, radiometer, and Langmuir probe also mounted on the port side, the Space Test Payload 1 (STP-1) multipurpose experiment support structure (MPESS) (just beyond gas beam), and the Air Force Program 675 (AFP-675) experiment support structure (ESS). |
