The launch mission is not to let the rocket directly from the ground platform vertical launch, but the aircraft took it to the air and then ignition.

First of all, the Orbital Stargazer L-1011 aircraft will take off from the U.S. state of Florida Cape venal corner of Kennedy Space Center, the rocket to the target region thrown over the Atlantic (elevation 39999 feet / 12192 meters).

Then, the Pegasus rocket will be released. 5 seconds later, the main engine ignition. During the follow-up, the other two engines will also be ignition, in order to NASA eight small satellites sent to the correct near earth orbit.

After that, the spacecraft will be split in two, and the separation module (tubular structure) will be executed once every 30 seconds. After about 10 minutes, it will automatically open the panel to collect solar energy, the entire process takes about 14.5 minutes.


3 hours later, NASA will begin to contact these satellites and carry out scientific research work, CYGNSS satellite will study the sea surface wind in the core of the Hurricane (as an important indicator of a strong storm).

NASA says many of the earth's science missions are unable to carry out such studies, which will help scientists better predict the intensity of a hurricane, or the level of storm that is about to be landed.

Tomorrow will be in the morning at 7:11 a.m. EDT, Orbital Stargazer aircraft will enter the runway at 7:26AM, the Pegasus rocket launch window will open in about an hour (8:19AM), satellite deployment from 8:24AM.
