'Does it pose a threat to civilian aviation? Our assessment is it does not. 'So the first question is does it pose a threat - physical kinetic threat to individuals in the United States or the U.S.
They decided not to 'take kinetic action due to the risk to safety and security of people on the ground from the possible debris field.'Ī defense source explained: 'We have to do the risk-reward here. They discussed shooting it out of the sky, but decided it was too risky to recommend. Present were Mark Milley, the chairman of the Joint Chiefs of Staff General Van Herck, commander of NORTHCOM/NORAD, and other combatant commanders, NBC reported. Montana is home to fields of underground Minuteman III intercontinental ballistic missile silos. It was flying above Billings, Montana on Wednesday, NBC reported. ABC News reported it was as big as three buses, and had what they termed 'a technology bay'. Sources told NBC News that there were concerns about the possible debris from shooting the balloon out of the sky. 'We continue to track and monitor it closely.'į-22 Raptors were sent from Nellis Air Force Base in southern Nevada, but they are not thought to have engaged with the balloon - their activities prompted a ground stop at the airport in Billings, however, with air traffic controllers citing a 'special military mission.' 'The United States government has detected and is tracking a high-altitude surveillance balloon that is over the continental United States right now,' Pentagon spokesperson Brig. The Pentagon opposed the move, fearing civilian casualties if the giant balloon - the size of three buses - is exploded in the air. The Associated Press contributed to this report.The balloon is seen in the skies above MontanaĪ massive Chinese surveillance balloon has been hovering over the northern United States for the last few days, senior defense officials confirmed on Thursday - with Joe Biden being briefed on Wednesday about his options, including shooting it out of the sky.īiden suggested the high-altitude balloon should be shot down, after it was spotted and reported by civilians in a commercial airliner, U.S. In order to confirm that the object is a newly discovered asteroid, more position data relative to background stars is required.
If confirmed as a new asteroid discovery, this detection would have implications for the understanding of the formation and evolution of the solar system. Small asteroids have been studied in less detail than larger asteroids due to the difficulty of observing such objects. In an analysis of this data, the team's results suggest the object measures 100–200 meters, occupies a very low-inclination orbit and was located in the inner main-belt region at the time of the Webb observations. The calibration team considered the observations to have failed for technical reasons, but data on the asteroid 10920 were used by the team to establish and test and new technique to constrain an object’s orbit and to estimate its size. They were not designed to hunt for new asteroids and were calibration images of the main belt asteroid 1998 BC1. The observations were published in the journal Astronomy and Astrophysics.
