NASA Image Fireball Tools Over Bering Sea



On December 18,
2018, big "fireball" – term used for
extremely bright meteors that can be seen on a wide area

exploded about 16 kilometers above the Bering Sea. Explosion
unleashed approximately 173 kilotonnes of energy or more than 10 times more energy
of the atomic bomb over Hiroshima during the Second World War. Two NASAs
aboard the Terra satellite have captured images of the remains of the big ones
meteor. The image sequence displays views of five of the nine-camera of the Polar Spectrometer Spectrometer (MISR) camera.

8, the fiery ball was the most powerful meteor to be observed since 2013;
however, given the height and the remote area in which it was located,
the object does not pose any threat to anyone on earth. Fireball events are actually fair
common and recorded in NASA's Near Earth Center
Survey database.

The Terra spacecraft was put into operation in 1999 and is run by NASA's Goddard Space.
Flight Center in Greenbelt, Maryland. The MISR tool is built and is
run by NASA Laboratory for Reactive Movement in Pasadena, California, for NASA
The Science Mission Directorate in Washington. JPL is a division of Caltech. Mostly,
MISR data was obtained from NASA's Langley Atlantic Research Center
Data Center in Hampton, Virginia. The MODIS tool is operated by NASA's Goddard
Space Flight Center
