Scientists find presence of minerals that formed in high temperatures in the comet dust returned by NASA’s Stardust mission. The presence of Olivine suggests that the material may have been formed near the center of the solar system, instead of outside the solar system, as previously believed.
NASA’S Stardust Mission
After seven years in space, NASA’s Stardust sample return mission returned safely to Earth when the capsule carrying cometary and interstellar particles successfully touched down at 5:10 a.m. Eastern time (3:10 a.m. Mountain time) in the desert salt flats of the U.S. Air Force Utah Test and Training Range.
