Standing by for F and H!

CYGNSS observatories A and C have been successfully deployed! Standing by for E and G in about 30 seconds.

The eight satellites will deploy in pairs at 30-second intervals beginning 13 minutes and 4 seconds into the flight.

Deployment of the CYGNSS payload is coming up in about five minutes. Now that the final engine burn is complete, the vehicle is in orbit.

The final burn of today's CYGNSS launch is underway with the ignition of the Pegasus XL rocket's third stage.

The protective payload fairing around the CYGNSS spacecraft separated and fell away as expected. Stage 2 has burned out. All milestones are taking place as expected.

All continues to go well in the early stages of flight. The first stage completed its burn and fell away as planned, followed by ignition of the second stage.

At 8:37 a.m. NASA's CYGNSS mission began with launch aboard the Orbital ATK Pegasus XL rocket. Stand by for updates from ascent.

Pegasus is away!
