The following is an updated time line for certain events in the Phase 3-B mission, starting with Ariane first stage ignition (H0) and ending with the first motor firing at fourth apogee. The clock time entries are based on a launch at the opening of the window on 16 June; a delay in the launch would of course not affect the elapsed time column. The "AOS/LOS" times early in the mission are only of academic interest, since the transmitter will most likely be kept off for five hours after launch to allow outgassing to hard vacuum. Times of various events during launch are approximate, as I do not yet have ESA final values for these (most of the entries in the ESA manual say "TBD".)
