Good idea, Paolo!
Dawn's ion engine have been OFF in the last hours (at least 9 hours from my checks) and, as expected, now spacecraft started to accelerate: at current distance, I espect an acceleration toward Vesta of 1,0e-4 m/s2; considering current phase angle, close to 90°, this should cause an increase of total velocity close to 1 mph each 2 hours... until next engines power on! -------------------- I always think before posting! - Marco -
