How Does It Effect Your S/C Design?
•Structure•Electronics•Solar Panels•Radio Communications
•Notes to consider―Deep space temperature range 4 deg K to 5800deg K.―Radiation effects – worse than any place else in LEO orbit.―Best radiation resistant FPGA - Actel

ANOMALIES RELATED TO RECENT SOLAR ACTIVITY
Collected by David Webb from various sources for events arising from recent flares, CMEs, and geomagnetic storms.
Oct. 23: Genesis solar wind satellite at L1 entered safe mode. Normal operations resumed on Nov. 3.

Nov. 2: Chandra observations halted again autonomously due to radiation. Resumption of observations will be delayed for days.
Nov. 6: Polar TIDE instrument reset itself and high voltage supplies were disabled; recovered within 24 hr.
Mars Odyssey spacecraft commanded out of Safe mode; operations nominal.
General:
Satellite operators: Satellites put into safe modes, solar panels rotated, operations reduced.
Power grid managers: Less use of and switching between systems.
