Russian marines take on more than 30 obstacles in a course that exceeds 10 kilometers.
Aftermath of the Chelyabinsk Meteor
A meteor weighing 10,000 metric tons exploded only 23km above the city of Chelyabinsk in Russia on February 15, 2013. Unlike previous such events, this time scientists had the highly sensitive OMPS instrument on NPP to deliver unprecedented data and help them track and study the meteor plume for months. This video shows how accurately the model prediction coincided with the satellite observations.
