Greetings Meteorite Friends! Have you wondered what is next for the OSIRIS-REx spacecraft after delivering its precious sample of asteroid Bennu? Join us Wednesday, Nov. 15 for the upcoming presentation by Dr. Daniella DellaGiustina to learn about the extended mission known as OSIRIS-APEX! (Great doorprizes will be on hand for those who attend in person).
Also, for those in the Washington, D.C. area, note that the Smithsonian Institution just unveiled a new OSIRIS-REx exhibit that includes a sample of asteroid Bennu! Here is another in the 2023 series of Lunar & Planetary Laboratory Evening Lectures at the University of Arizona in Tucson: LPL Evening Lecture Wednesday, Nov. 15, 2023 7:00p.m. (Arizona) Kuiper 308 or Zoom webinar<https://bit.ly/LectureDaniDellaGiustina11152023> Dr. Daniella DellaGiustina Assistant Professor, Lunar and Planetary Laboratory Exploring Hazardous Asteroids with the OSIRIS Spacecraft The Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer (OSIRIS-REx) spacecraft mission characterized and collected a sample from asteroid (101955) Bennu. After the OSIRIS-REx Sample Return Capsule is released to Earth's surface in 2023, the spacecraft will divert into a new orbit that encounters asteroid (99942) Apophis in 2029, enabling a second mission with the same unique capabilities: OSIRIS–Apophis Explorer (APEX). On April 13, 2029, the 340-m-diameter Apophis flies within ~32,000 km of Earth's surface, <1/10th the lunar distance. Apophis will be the largest object to approach Earth this closely in recorded history. This rare planetary encounter will alter Apophis' orbit, subject it to tidal forces that change its spin state and may seismically disturb its surface. APEX will distantly observe Apophis during its Earth encounter and capture its evolution in real-time, revealing the consequences of an asteroid undergoing tidal disturbance by a major planet. The spacecraft's instrument suite will subsequently provide high-resolution data of a "stony" asteroid—advancing knowledge of these objects and their connection to meteorites. Near the mission's end, APEX will perform Regolith Excavation by S/C Thrusters; a technique demonstrated at Bennu. Observations during and after excavation will provide insight into the material properties of stony asteroids. Furthermore, Apophis' material and structure have critical implications for planetary defense. ___________________________________________________________________________________________________________________________________________________ This event is free and open to the public.
