CYGNSS (Cyclone Global Navigation Satellite System)

Since Nov. 26, NASA's Cyclone Global Navigation Satellite System (CYGNSS) team has not been able to make contact with one of the eight CYGNSS spacecraft, FM06. The team is currently still working to acquire a signal and establish a connection. The other seven spacecraft continue to operate normally and have been collecting science measurements since …

We have successfully contacted each of the 8 observatories on our first attempt. This bodes very well for their health and status, which is the next thing we will be carefully checking with the next contacts in the coming days. It is an amazingly rewarding feeling to spend such an intense and focused time working …

The eighth CYGNSS satellite was contacted at 3:30 p.m. EST through the Chile ground station — 100-percent success! Full constellation redundancy achieved.

CYGNSS satellite six was contacted at 3:01 p.m. EST, seven at 3:28 EST, both by the ground station in Chile. One more to go!

The fifth CYGNSS satellite was contacted at 1:53 p.m. EST — also at a Chile ground station. Three to go!

The fourth satellite was contacted at 1:48 p.m. EST through a ground station in Chile — four more to go!

The second satellite was contacted at 1:21 p.m. EST through our Hawaii ground station, the third at 1:24 p.m. Both are healthy. Five to go!

Contact was successfully established at 11:42AM EST through the Hawaii ground station. Contact with the second CYGNSS micro-satellite is expected at approximately 1:20pm EST.

Hurricane forecasters will soon have a new tool to better understand and forecast storm intensity. A constellation of eight microsatellites, called NASA's Cyclone Global Navigation Satellite System mission, or CYGNSS, got a boost into Earth orbit at 8:37 a.m. EST today, Dec. 15, aboard an Orbital ATK Pegasus XL rocket. The unique, air-launched vehicle was …
