Risk examples for the mission classified following ECSS-M-ST-80 (2008) for their their likelihood (A [low] to E [high]) and their severity (1 [low] to 5 [high]).
|Possible scenario||Risk||Index||Proposed action|
|Launch fails||A5||Low||No action - mission failed|
|Failure of one spacecraft||B5||Medium||Continue mission with remaining spacecraft, focus on scientific research|
|Launch misses time window||C2||Low||Wait 19 months for the next time window|
|Miss the trajectory for GAM||B5||Medium||Mission failed|
|Collisions of spacecraft during deployment||B4||Low||Communicate to spacecraft and try to recover possible orbit problems with propulsion system|
|Not enough data rate during safe mode to ensure communication between spacecraft and ground station||B3||Low||Spacecraft are on a circular orbit pointing to the Sun. Wait until spacecraft is closer to the ground station, where higher data rate is possible. Two small emergency antennas (70 m dish ground station)|
|Damage of sensitive optics of a coronagraph during space flight||B3||Low||Analyze the influence of the damage and try to reduce it using image processing at the science ground station|
|Radiation damage of the measurement system caused by GCR background and SEPs||D2||Medium||Expected damage, which limits the lifetime of the measurement system. Possible to move spacecraft slightly in order to protect them.|
|If the spacecraft enters safe mode in a 40° range on the backside of the Sun, connection will not be possible in this area||B3||Low||Ask communication specialist. Communicate with spacecraft, when it leaves the 40° area behind the Sun and recover it|
|Blackout of measurements device||A3||Low||Ask payload specialist. Check the whole spacecraft housekeeping system, special communication time to the spacecraft|
|Explosion of some propulsion tank after deployment||A4||Low||Check damage, continue mission with remaining spacecraft|
