The Sun Sets on Delta

United Launch Alliance launched a Boeing Delta IV on May 16 with a global positioning satellite for the U.S. Air Force.

GPS Block IIF replaces an earlier group of satellites launched in the 1990s.

Above is video of the launch I filmed from about three miles west of Launch Complex 37.

The launch was at 8:03 PM EDT, just before sunset, so the vapor trail was lit in colors of pink, yellow and orange.

The vapor trail left after the launch. Photos credit:

Note the shadows cast by the vapor trail.
