Florida: Spectacular Dawn Rocket Launch Today!
September 2, 2015 16 Comments
We had an absolutely spectacular Atlas 5 rocket launch this morning of a Navy MUOS communications satellite into orbit. The 20-story tall rocket lifted off at 6:18 am. The dawn sky brightened as the rocket took off and rose up. Then we saw something we had never seen before – the white rocket plume brightened into an enormous tadpole-like cloud of mist as the rocket arced east across the Atlantic. The phenomenon was caused by the perfect combination of sun angle below the horizon and high humidity. The white cloud of water vapor (not smoke) was formed when the rocket’s hot exhaust gases hit the air. It was an amazing sight, and one of the top two launches we have ever seen!
