| Title |
STS-39 AFP-675 and STP-1 MPESS in OV-103's payload bay (PLB) |
| Description |
An overview of Discovery's, Orbiter Vehicle (OV) 103's, aft payload bay (PLB) documents a variety of STS-39's payloads. In the foreground is the Space Test Payload 1 (STP-1) multipurpose experiment support structure (MPESS) with the Spacecraft Kinetic Infrared Test (SKIRT) (left), ascent particle monitor (APM) (center), and advanced liquid feed experiment (ALFE) (two canisters) visible. Behind the STP-1 is the Air Force Program 675 (AFP-675) experiment support structure (ESS) with ESS tape recorders (left), Uniformly Redundant Array (URA) (front),and Cryogenic Infrared Radiance Instrumentation for Shuttle 1A (CIRRIS-1A) (center back) visible. The ESS pallet power distribution system thermal covering (gold-colored) is visible at the bottom. AFP-675 is a Department of Defense (DOD)-sponsored collection of experiments whose objective is to gather data on the Earth's atmosphere (aurora, Earth limb, and airglow), celestial objects, and the environment in and around the PLB.

STS-39 OV-103 reaction control system (RCS) jets fire during onorbit maneuver |
| Description |
During STS-39 rendezvous maneuvers, two of Discovery's, Orbiter Vehicle (OV) 103's, right reaction control system (RCS) jets fire (one up and one to the right). The RCS jet firings create a glow around OV-103's orbital maneuvering system (OMS) pods and vertical tail against the blackness of space. Some reflection from the crew compartment windows is visible. In the foreground are the Space Test Payload 1 (STP-1) multipurpose experiment support structure (MPESS) (front) and the Air Force Program 675 (AFP-675) experiment support system (ESS) (back). The remote manipulator system (RMS) arm is stowed along the port side sill longeron. |

STS-39 Critical Ionization V
…
| 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). |
