Probability in 20 years Interplanetary cruise: 5σ navigation error = 0.02% (400 km error acceptable with 1σ error = 80 km; assumes Gaussian error distribution) Mars intercept = 35% (geometric factor considering B-plane dispersions; only some navigation error cause spacecraft to hit Mars) 2. Mars orbit insertion probability of spacecraft destructive “disassembly” = 1% (this estimate is based on the observation that only about a dozen satellites experienced major propulsion malfunction, out of 1000+ satellites known to be launched with substantial propulsion capability) probability of descent module ejected with adequate dv = 1% (based on possible distribution of mechanical momentum of resulting debris and considering geometric factors for spreading of this debris cloud) 3. 5. 0.006% 0.006% 0.010% 0.010% Initial transfer/phasing orbit 0.050% spacecraft failing in this orbit = 5% (simple ratio of duration in this orbit - 3 months and total spacecraft lifetime - 5 years) unique LON/Periarg combination = 1% (conservative estimate, based on fact that >100 combinations were tested and no rapid-decay combination was found -- though they are known to exist) 50 year estimate based upon linearly extrapolating the 20 year probability out to 50 years 4. Phobos orbit operations Probability in 50 years 0.1250% 0.000% 0.000% Trans-earth departure 0.010% probability of 180-deg inverted burn = 0.1% (based on the fact this error was observed only a few times over many thousands of actual inspace propulsion maneuvers) probability of inverted burn causing Mars entry = 10% (based on geometric and energy considerations of this particular maneuver) 0.010% Total estimate ~0.08% ~0.15% 11-15 October 2010 Requirement 1% 5% Margin of estimate over requirement 12x 33x 1MS-3 LOUIS FRIEDMAN Planetary Protection The Phobos LIFE experiment is fully compliant with the COSPAR planetary protection guidelines. 19 Some Tests to be Done After Sample Return Culture the spores and count the vegetative cell forms, compare with negative controls Mutation Morphological characteristics before and after the mission (EM analysis) Biochemical activities before and after the mission Contamination control Viability/Capability of Self-propagation Culture each organism in their optimal culture conditions, and compare the growing cell number with the negative controls.
