Lat month, a fiery meteor was detected in Greenland close to a U.S. Air Force base with 2.1 kilotons of force, as reported by scientists on Twitter.
On July 25, an object moving at about 15 miles/second (24.4 kilometers/second), or 54,000 mph (87,000 km/h), was identified near Thule Air Base. The U.S. Air Force did not immediately report the event or respond to the crash, according to The Aviationist. However, Air Force spokeswoman Capt. Hope Cronin said in an email to Military.com that no one was injured and that the meteor didn't affect or harm any activity at the base.
Though concerning, the object had a relatively small effect. "By comparison, the 2013 meteor over Chelyabinsk, Russia released over 200 times the energy of the Greenland meteor," JoAnna Wendel, a NASA spokeswoman, said in the report by Military.com. NASA's Jet Propulsion Laboratory (JPL) confirmed the object's speed, though the actual size of the meteor remains unknown. It was also reported that the object was about 27 miles (43 km) north of Thule Air Base.
Hans Kristensen, director of the Nuclear Information Project for the Federation of American Scientists, and Ron Baalke of JPL, also known as "Rocket Ron," a "Space Explorer at the Jet Propulsion Laboratory" on Twitter, have discussed the impact on Twitter. Baalke reported the event, while Kristensen added that the event did not seem to be any sort of attack.
We’re still here, so they correctly concluded it was not a Russian first strike. There are nearly 2,000 nukes on alert, ready to launch.
It is not uncommon for small asteroids to enter Earth's atmosphere and turn into bolides, or fireballs, according to data from NASA's Near-Earth Object program. "Meteors of this magnitude or greater, caused by the impact of small asteroids (a few meters in size) with Earth's atmosphere, occur a few times a year," Wendel said.
