SpaceX Launches X-37B
A SpaceX Falcon 9 rocket launched the U.S. Air Force's X-37B space plane into orbit on Sept. 7, 2017. The robotic spacecraft will conduct its fifth secret mission for the military while in orbit. This mission,

A Cloudy Sky
SpaceX launched the X-37B mission just days ahead of the expected arrival of Hurricane Irma in the Florida area. Early forecasts called for a 50-percent chance that bad weather would prevent a launch.
The X-37B in Orbit
The X-37B space plane uses solar panels to provide power during its long missions in Earth orbit.
Smooth Ascent
Any weather fears evaporated during the countdown as conditions were clear for the Sept. 7 launch. Here the Falcon 9 soars into orbit from Pad 39A at NASA's Kennedy Space Center.
How the X-37B Works
The U.S. Air Force's robotic X-37B space plane is a miniature space shuttle capable of long, classified missions in orbit. See how the X-37B space plane works in this Space.com infographic.

Reaching 'Max Q'
About 1 minute and 20 seconds after launch, the Falcon 9 rocket passed through the region of maximum dynamic pressure, or "Max Q," where the aerodynamic force in front of the rocket is at its strongest.
