This is the first in-flight AO. The second and final in-flight AO is foreseen to take place in approximately a year's time. At that point it is expected to have a more accurate estimate of the mission lifetime.

Like all previous AOs, the final AO will have two parts: GT2 and OT2. There is very little GT still unallocated. The amount of time to be offered in OT2 will depend on the predicted mission lifetime and the need of observations for efficient scheduling.
