Flight hardware

Space transportation system An integrated sytem consisting of the Space Shuttle (Orbiter, External Tank [ET], Solid Rocket Booster [SRB], and flight kits), upper stages, Spacelab, and any associated flight hardware and... 

The Rosetta mission imposed very strict requirements on the flight hardware. The electronic components had to withstand a high radiation dose during the more than 10- year flight and had to operate within a wide temperature range and with low power consumption. 

Like in other space projects, different test environments exist for the development and validation of the OBSW. These range from a pure software emulator (which provides great flexibility, like full introspection, fault injection, and debugging capabilities) to the actual flight hardware with additional components to simulate the environment (providing the maximum possible representativity). Examples are ... 

Evidence examined in the review of space shuttle material, manufacturing, assembly, quality control, and processing of nonconformance reports found no flight hardware shipped to the launch site that fell outside the limits of shuttle design specifications. 

Launch site activities, including assembly and preparation, from receipt of the flight hardware to launch were generally in accord with established procedures and were not considered a factor in the accident. 

The Prometheus flight hardware shall be designed and verified to meet applicable functional, performance, operation, and other design requirements without damage or degradation when exposed to the design environments specified herein in ERD). (Ref 1-9) In addition to particle and radiation environments described above, the module must withstand launch loads and other space environments. Section 10 has more details about environments. 

The pre-launch environments primarily comprise the atmospheric and dynamic conditions to which a component or assembly will be exposed prior to launch. These do not include the simulated launch and flight environments to which hardware is subjected during test events. Generally, pre-launch environments are controlled so that they do not drive the design of flight hardware. These include,...
