Space Environment Screening

Space Environment Screening

Workflow

• Confirm that the task does not include restricted mission details, protected launcher data, controlled requirements, or partner-private spacecraft information.
• State the environmental frame before calculating: orbit or trajectory, altitude, inclination, eclipse assumptions, pointing law, Sun keepout, Earth view, mission duration, and operating or survival mode.
• Separate public-confirmed mission facts from assumptions and placeholders.
• Screen environment in coupled passes:
  • solar flux, Sun angle, and shadowing
  • Earth IR and albedo
  • thermal transients and survival temperatures
  • radiation dose, displacement damage, and single-event exposure
  • coating or detector degradation
  • contamination, venting, and cleanliness assumptions
  • operations constraints such as safe mode, decontamination, or heater duty cycle
• Label simple models as screening-level and state which standards, detailed analyses, or vendor data would be needed later.

Checks

• Spacecraft or payload surfaces have plausible Sun, Earth, radiator, and deep-space views.
• Hot, cold, eclipse, survival, and powered states are not conflated.
• Detector, electronics, coatings, adhesives, and mechanisms are screened against the relevant environment, not just the optics.
• Shielding assumptions are stated in material and thickness terms when radiation numbers are reported.
• Pointing and keepout assumptions are consistent with the claimed science mode.
• Environment inputs flow into requirements, budgets, and verification gaps.

Output Expectations

• Return assumptions, screening calculations, and risk notes in a traceable form.
• Flag values that need mission-specific analysis, standards lookup, vendor confirmation, or spacecraft-interface data.
• Do not imply qualification or flight acceptance from a screening calculation.
