Dear Colleagues,
  
There will be an Astronomy and Space Science seminar on 05/16, 04:30 PM, in the Auditorium, Kyung Hee University Astronomical Observatory.
 
Prof. Ian Garrick-Bethell of University of California, Santa Cruz will give a presentation about "Age of the lunar South Pole-Aitken basin"
The language of the seminar will be English and abstract is shown below.
  
You are asked to join the seminar five to ten minutes before it starts. Your attendance will greatly be appreciated.

Thank you.

Abstract: The lunar farside South Pole-Aitken (SPA) basin is the oldest and largest impact basin on the Moon.  However, the age of the basin is unknown.  Determining its age would help determine the ages of all of the Moon's subsequent basins.  A sample return mission to date the basin has been a high priority for almost 20 years, as identified by the US National Academies, and numerous proposals to NASA's mission programs.  Here I present evidence that the age of the SPA basin can be fairly well established as 4.23 billion years old, based on Apollo sample 76535, Dhofar meteorite 489, and the statistics of craters on its surface.
