2 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 Some slides by Dr. J.

12 19 November 2003 ANOMALIES RELATED TO RECENT SOLAR ACTIVITY Collected by David Webb from various sources for events arising from recent flares, CMEs, and geomagnetic storms. david.webb@hanscom.af.mil Oct. 23: Genesis solar wind satellite at L1 entered safe mode. Normal operations resumed on Nov. 3. Some slides by Dr. J. Cutler – Univ. of Michigan Space Environment - I Introduction to Space Systems and Spacecraft Design Space Systems Design

13 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. Some slides by Dr. J.
