Peter Jenniskens points our attention at a recently published meteor related paper:

Asteroid that hit Botswana in 2018 likely came from Vesta

This article appeared online on the SETI institute website.

 

Abstract:  April 23, 2021, Mountain View, CA — An international team of researchers searched for pieces of a small asteroid tracked in space and then observed to impact Botswana on June 2, 2018. Guided by SETI Institute meteor astronomer Peter Jenniskens,  they found 23 meteorites deep inside the Central Kalahari Game Reserve and now have published their findings online in the journal Meteoritics and Planetary Science.

“Combining the observations of the small asteroid in space with information gleaned from the meteorites shows it likely came from Vesta, second largest asteroid in our Solar System and target of NASA’s DAWN mission,” said Jenniskens. “Billions of years ago, two giant impacts on Vesta created a family of larger, more dangerous asteroids. The newly recovered meteorites gave us a clue on when those impacts might have happened.”
