IceBridge Retraces 2010 SEAT traverse route
By Lora Koenig Yesterday was an exciting day in the office. While I was downloading satellite data, answering e-mails and tying up loose ends before leaving for Antarctica, I was also closely following the NASA Airborne Sciences Flight Tracker and the flight path of the NASA DC-8 aircraft. The DC-8 is currently flying over Antarctica […]
Taurids Dust the November Sky
The Orionid meteor shower is over, as Earth has finally left the wide stream of debris produced by Comet Halley. However, we are now encountering particles produced by Comet Encke, the second comet to be assigned a name (Halley was the first). This debris wake is much larger, lasting many weeks, causing the Taurid complex …

Images of Rare Aurora in Southern Tennessee
The colors of emitted light within an aurora depend on the initial energy of the charged particles (mostly electrons) cascading into Earth’s atmosphere. Electrons with higher initial energies are able to penetrate deeper into the atmosphere, whereas those with lower initial energies lose all their energy at higher altitudes. The blue aurora emitted from low-altitude …
From Athens to Tuscaloosa — In 3 Seconds!
MSFC’s all sky meteor camera recorded this bright meteor last night (November 1st) at 9:04 pm CDT.
