“Exploring Mars with Curiosity” is the topic of this month’s USGS public lecture on Thursday, Oct. 25 at 7:00 pm. Ken Herkenhoff of the USGS Astrogeology Science Center is the speaker. According to the press release: “In early August, the Mars Science Laboratory rover known as ‘Curiosity’ landed successfully to begin its 23-month mission of searching the Martian surface for evidence of environmental conditions capable of supporting microbial life. Find out what scientists have discovered so far during this mission, particularly what they have found at the Gale crater landing site. Also how scientists are using special instruments aboard Curiosity to analyze dust and rocks to learn about the role of water in forming the Martian landscape. The lecture takes place at 345 Middlefield Rd, Bldg. 3, Conference Room A in Menlo Park.
