Mars 2020 Hero

Ground Support Equipment (GSE) is critical to spacecraft build. The equipment can be quite large, including hardware rotation fixtures, cranes, hardware used in specialized lifts and moves, shipping crates, and tall ballymores and ladders. This type of GSE is complex and extremely large. GSE also includes electrical cables, tools, vacuum hoses, computers, phones, tables, benches, chairs and any other non-flight equipment used to support the assembly activities.
