Rationale: Exposure to atomic oxygen degrades many materials and requires mitigation to ensure full Instrument function over the design mission lifetime. Atomic oxygen levels in GEO are negligible and are only significant for GEO-bound Instruments that spend extended times in LEO prior to GEO transfer. Instrument Developers should conservatively estimate the atomic oxygen environment for their orbit(s), orbital lifetime and launch date relative to Instrument’s specified the solar cycle. One source for predictory models is the Community Coordinated Modeling Center (CCMC) at http://ccmc.gsfc.nasa.gov/index.php Electromagnetic Interference & Compatibility Environment The Instrument should function according to its specification following exposure to the Electromagnetic Interference and Electromagnetic Compatibility (EMI/EMC) environments as defined in the applicable sections of MIL-STD-461. Rationale: Exposure of the hosted payload instrument to electromagnetic fields may induce degraded performance or damage in the instrument electrical and/or electronic subsystems. The application of the appropriate environments as described in the above noted reference and in accordance with those test procedures defined in, or superior to, MIL-STD-461 or MIL-STD-462, will result in an instrument that is designed and verified to assure full instrument function in the defined EMI/EMC environments. Note: the environments defined in MIL-STD-461 may be tailored in accordance with the Host Spacecraft, launch vehicle and launch range requirements.
