jsc2019e050038 (8/12/2019) --- Photo documentation taken during the NG-12 Crew Equipment Interface Test (CEIT) The view is of a SAFFIRE sensor. The NASA Advanced Exploration Systems program began a project to develop and demonstrate spacecraft fire safety technologies in relevant environments. The keystone of these demonstrations is a large-scale fire safety experiment conducted on an International Space Station (ISS) re-supply vehicle after it has undocked from the ISS and before it enters the atmosphere.

jsc2023e046377 (12/14/2019) --- A view of the Spacecraft Fire Safety Experiments (Saffire) VI experiment hardware, loaded inside the Northrop Grumman (NG) Cygnus cargo vehicle for the 19th NG resupply mission to the International Space Station. Saffire is a series of experiments to investigate how fire spreads on a variety of combustible materials in the microgravity environment. The experiments are ignited in the Cygnus cargo spacecraft after it departs the space station and before it reenters the Earth's atmosphere. Saffire-VI builds on prior results to test flammability at different oxygen levels and aims to further knowledge of realistic flame spread to aid the development of fire safety equipment and strategies for future spacecraft.

iss061e147761 (1/31/2020) --- A view from the Unity module aboard the International Space Station (ISS) of the Northrop Grumman NG-12 hatch. Attached to the hatch is the SlingShot small satellite deployer loaded with eight CubeSats that were deployed into Earth orbit for communications and atmospheric research several hours after Cygnus departed the orbiting lab on Jan. 31, 2019. The deployed CubeSats include: SEOPS-CIRiS, SEOPS-EDGECUBE, SEOPS-MakerSat, SEOPS-MiniCarb, SEOPS-ORCA, SEOPS-Quantum Radar, SEOPS-UbiquitiLink and SEOPS-VPM.
