MECO-1.

T+10 minutes, 13 seconds. We have SECO-1, and the second stage has directly inserted itself into the proper orbit to deploy the two GRACE-FO spacecrafts.

Deployment should occur 80 seconds after SECO-1.

GRACE-FO separation confirmed. Each of the two spacecrafts weigh 580 kilograms and will work together to continue the mission of tracking water movement throughout our planet.

Now in 45mins coast to Stage 2 re-ignition.

Since the M-Vac restart won't occur for another 45 minutes, I'll cut away for the time being, relax during the coast phase, and be back in time for the second burn.

Do not have AOS on satellite #2 yet. edit: indication was that they have to switch frequencies for #2

NASA TV is reporting that they only got downlink from the first of the two Grace Sats but they will wait till passage over the north pole to get the second.
