Expedition 74

NASA’s Northrop Grumman Commercial Resupply Services 24 spacecraft is named in honor of NASA astronaut Steven Nagel. Selected by NASA in 1979, Nagel is a veteran of four space flights (STS-51G and STS-61AA in 1985, STS37 in 1991, and STS-55 in 1993) and has logged more than 723 hours in space. Nagel died in 2014.

NASA astronaut and Expedition 74 flight engineer Jessica Meir’s reflection is captured in a spacesuit helmet visor. The visor assembly is coated with a microscopic layer of gold that reflects infrared radiation to protect an astronaut’s eyes while allowing visible light to pass through. Meir was working inside the International Space Station's Quest airlock, installing leg and arm components on the spacesuit and swapping components from one suit to another.

NASA astronauts Chris Williams and Jessica Meir, both Expedition 74 flight engineers, inspect and configure a spacesuit jetpack, known as the Simplified Aid for EVA Rescue (SAFER), inside the International Space Station’s Destiny laboratory module. The jetpacks attach to the rear of spacesuits and serve as a safety mechanism that allows a spacewalker to maneuver back to the station in the unlikely event they become untethered from their worksite.
