Summary
8 x CYGNSS launched on an Orbital ATK Pegasus XL from Cape Canaveral, Air launch to orbit on December 15, 2016. It was Orbital ATK's 2nd launch, 2nd this year and humanity's 5,610th orbital launch attempt. It was the 29th Pegasus XL flight and the 1st this year. The payload was bound for low Earth orbit (LEO). CYGNSS FM05, one of 9 catalogued objects, reached a 526 × 539 km orbit inclined 35.0°. 9 objects from this launch are catalogued, 8 of them payloads.

About this launch
CYGNSS or Cyclone Global Navigation Satellite System is a NASA developed system to improve hurricane forecasting. It is a constellation of 8 small observation satellites, 27.5 kg each, that will make accurate measurements of ocean surface winds in and near the eye of the storm throughout the lifecycle of tropical cyclones, typhoons & hurricanes.
