Space Mega Meteor Run6/26/2021
And Russell says The Winchcombe meteorite fall is very timely, as the rock is similar to Ryugu in many ways, and we can use the meteorite to rehearse for mission analyses.From a video by Ben Stanley, processed by Markus Kempf, the AllSky7 network Just before 10 P.M.Feb. 28, a dazzlingly bright meteor traversed the U.K.s western sky, glowing for about six seconds.
Hundreds of people who happened to glimpse the sight took to social media to report what they saw, wondering if their eyes had been playing tricks on them or even if they had just seen a visitor from outer space. Maybe youve even enjoyed watching meteor showers throughout the year. These exceptionally bright meteors streak across the sky with a magnitude greater than 4. Like the larger space rocks that spawn them, meteorites range widely in size. The 1920 meteorite that landed in Hoba, Namibia, for instance, weighs 66 tons (60 metric tons), while the 1949 Beddgelert meteorite that landed in North Wales in the U.K. The pictures taken as part of this project provide vital information about the paths these rocks take through our atmosphere. By comparing images taken from different locations, observers can trace the meteors path to help deduce where surviving fragments may have landed. And using this technique, UKFAll aims to recover such meteorites. Thanks to this collaboration, UKFAll was able to calculate where pieces of the most recent U.K. These were a mixture of eyewitness reports, footage from doorbell cameras, and photographs. Using information from this network of cameras and footage from the public, UKFAll recreated the fireballs flight path to determine possible landing sites in Gloucestershire. Mary McIntyre, an active UKMON participant, tells Astronomy, This is a huge win for citizen science in that so many cameras caught the event across so many networks, and everybody worked together quickly to calculate the strewn field the area where debris might have landed. Several pieces of meteorite were recovered from a residential driveway in Winchcombe, as well as other nearby locations. The black, charcoal-like fragments were quickly retrieved by the Wilcock family, who owns the property. Several other fragments were discovered scattered around the local area. The museum has obtained nearly 11 ounces (300 g) of material from whats now officially named the Winchcombe meteorite. These are some of the most pristine, unaltered material in the solar system. Astronomers believe carbonaceous chondrites come from asteroids in the outer regions of the main belt. And their rare composition of minerals and organic compounds including amino acids can provide valuable information about the origin of our solar system, the formation of the planets, and the building blocks of life. Plus, the pieces are in such good condition that they are comparable to the samples returned by space missions, both in quality and quantity. For context, the Japanese Hayabusa2 mission recently returned 0.16 ounce (4.5 g) of material from asteroid Ryugu, which the museum is also helping characterize.
