CARA Risk Assessment Thresholds

Hejduk, M. D.
View original source ↗Export metadata ↓

Abstract

Warning remediation threshold (Red threshold): Pc level at which warnings are issued, and active remediation considered and usually executed. Analysis threshold (Green to Yellow threshold): Pc level at which analysis of event is indicated, including seeking additional information if warranted. Post-remediation threshold: Pc level to which remediation maneuvers are sized in order to achieve event remediation and obviate any need for immediate follow-up maneuvers. Maneuver screening threshold: Pc compliance level for routine maneuver screenings (more demanding than regular Red threshold due to additional maneuver uncertainty).

NASA CA Operations Devolution: Status Update

What is Devolution? Devolution is a spreading of CA (Conjunction Assessment) operations responsibilities to mission FOTs (Flight Operations Teams): Permits efficiencies in handling the increased workload caused by Space Fence and large constellations; Missions given more flexibility in choosing specific approach to CA requirements that resonates best with their particular needs; CARA (Conjunction Assessment Risk Analysis) retains Agency oversight through an established NASA Standard - will establish requirements for devolved CA preparations, processing, and operations conduct. Devolution is a PROPOSED paradigm under consideration by SMD (Space Missions Directorate): Number of activities required before Agency-level decision can be rendered; Agency requirements established via approved CA Standard; Operational experience testimony from two separate pilot programs; After these activities complete, decision will be made whether devolution is a feasible option for missions; CARA is recommending devolution to exist as an option for missions.

History of Late-Notice HIEs

Question was raised: are we seeing more late-notice events in recent months? Two definitions oflate-notice used to compare data: Event has at least one data point between TCA-4 days and TCA-2 days where the Pcwas below 1E-7, OR there were no data points in that timeframe. Event has at least one data point between TCA-2days and TCA where the Pc was at least 1E-4Event has at least one data point between TCA-4 days and TCA-2 dayswhere the Pc was below 1E-5, OR there were no data points in that timeframe. Event has at least one data pointbetween TCA-2 days and TCA where the Pc was at least 1E-4. The case studies that were examined all fall within criteriafor both definitions Terra vs 38192; TCA 24 JUN 2015Aura vs 89477; TCA 29 AUG 2015Terra vs 37131; TCA 19 DEC2015GPM vs 28685; TCA 5 SEP 2015.
