Video: Fireball in the sky over southeast US

A super bright meteor fireball was visible over the southeastern USA during the early hours of August 28th: Fireball outshines moon:  NASA cameras captured video of a meteor streaking past the moon. The fireball was one of the brightest observed by NASA in the past five years. – CSMonitor.com

“Recorded by all six NASA cameras in the Southeast, this fireball was one of the brightest observed by the network in 5 years of operations,” Bill Cooke, head of the Meteoroid Environment Office at NASA’s Marshall Space Flight Center in Huntsville, Ala., wrote in a blog post Tuesday (Sept. 3).

“From Chickamauga, Georgia, the meteor was 20 times brighter than the full moon; shadows were cast on the ground as far south as Cartersville.”

Here’s a brief video of the fireball talken by a NASA camera:

Caption:

Early Wednesday morning, at 3:27:20 AM Eastern Time, a piece of an asteroid, about 2 feet in diameter and weighing over 100 pounds, entered Earth’s atmosphere above the Georgia/Tennessee border, just south of Cleveland. The meteor was moving northeast at 56,000 miles per hour, and began to break apart north east of Ocoee, at an altitude of 33 miles. A second, fragmentation occurred less than half a second later, at an altitude of 29 miles. NASA cameras lost track of the fireball pieces at an altitude of 21 miles, by which time they had slowed to a speed of 19,400 mph. Sensors on the ground recorded sound waves (“sonic booms”) from this event, and there are indications on Doppler weather radar of a rain of small meteoritic particles falling to the ground east of Cleveland, Tennessee.

The SciShow‘s Hank Green talks about some benefits from the ISS:

We all know it’s awesome, and we could watch Chris Hadfield sing all day, but do you know about the awesome science that’s being done on the International Space Station? Hank explains three big discoveries made on the ISS that you should know about.

Minotaur V launch of lunar probe to be visible in wide area

On Friday night at at approximately 11:27 p.m. EDT, Orbital Sciences will launch a five-stage Minotaur V rocket from the Wallops Island spaceport on the Eastern Shore of Virginia. It will send NASA’s LADEE science probe to orbit the Moon: Orbital Set to Launch NASA’s LADEE Lunar Orbiter Aboard Minotaur V Rocket.

The launch will be webcast on NASA TV but if you are in a region from South Carolina to Maine and inland as far as West Virginia, you may see at least a portion of the launch. Check the Launch visibility map.

Updates on the launch status can be found here: Minotaur Launch Report | Mission Status Center – Spaceflight Now.

 

Project Morpheus flight test today [Postponed]

Project Morpheus plans another test flight of their rocket lander vehicle today – Twitter / MorpheusLander:

Aiming for ~1pm CT ignition! When we go live, it’ll be here: http://1.usa.gov/mr3Ybo  You can follow our Twitter feed there as well!

The pointer is to the webcast page at  Project Morpheus : Live.

Update: The test has been postponed – Morpheus Lander (MorpheusLander) on Twitter:

  • “Bummer News! We are postponing our test today. Here is the condensed explanation… Safety is priority! And,”
  • “Since this is our 1st Ground Takeoff & land with “Bravo” vehicle, we are scrutinizing everything in major detail…”
  • “We had some instruments that showed questionable data, & we want to run more tests before we execute this important test.”
