Atlas V Launched
updated: Apr 03, 2014, 8:26 AM

By the Dedicated Staff of edhat.com

Atlas V rocket carrying the DMSP F-19 military weather satellite launched from Vandenberg AFB Thursday morning around 7:46 am.

"At liftoff, the Atlas will rise vertically from SLC-3 for several seconds before it slowly begins to pitch over and head southward. The vehicle will briefly produce a contrail as it passes through a zone that extends roughly from 33,000 to 38,000 feet above sea level."

"The Atlas V rocket variant for slated for launch on Thursday uses liquid propellant engines, but no strap-on solid rocket motors. Unlike solid motors, which produce a brilliant flame, liquid propellant engines produce a much fainter flame. At launch time, the Sun will be above the horizon, creating a bright sky background. The rocket's use of liquid propellants and the bright sky will greatly diminish the visibility of the launch."
