Ancient life on Mars

The New England Aquarium at Central Wharf Simons IMAX Theatre will welcome Dr. John P. Grotzinger of the California Institute of Technology in the eighth annual John H. Carlson Lecture in conjunction with the Massachusetts Institute of Technology, at 7 p.m. on Thursday, Oct. 11.

In “Searching for Ancient Life on Mars,” Grotzinger will discuss NASA’s 20-year exploration of the red planet’s earliest history and the search of signs of life. These missions discovered that in contrast to its current harsh environment, the ancient surface of Mars was wet with a warmer climate and thought to have been habitable by simple microorganisms. The question for future missions is how to determine if life ever originated on Mars. The 2020 rover mission will collect rock samples to be examined with the most technologically advanced scientific instruments, giving scientists the best chance to date to search for fossils of ancient life.

The lecture is free, but registration is required and can be made at www.neaq.org or by calling 617-973-0235.
