Join Ken Lum ([masked], Cell: [masked]) at the Safeway parking lot at Sharon Park in Menlo Park off Sand Hill Rd. at 10:00 AM for an easy going ride through Shoreline Park to the SETI Institute at 189 Bernardo Ave. in Mountain View for their weekly noon time talks on astronomy, physics and astrobiology. We will meet in the corner of the parking lot nearest the Shell gas station. This week's talk will be about "Is Planetary Defense Feasible - DE-STAR: A Planetary Defense and Exploration System" by Philip Lubin of UC Santa Barbara. For more on the talk, visit the SETI web site at: www.seti.org. We will pick up lunch at the Subway sandwich shop in Mountain View to take to SETI or eat afterwards in Los Altos. Anyone wanting to skip the lecture may return on their own via any of the alternative routes outlined on the route sheet. Rain or Asteroid collision cancels.
