Howdy, Martians! Now that compelling evidence suggests life on Mars, what on earth should we do next? Norman R. Haynes, of the Mars Exploration Directorate at Pasadena's Jet Propulsion Labs, discusses past and proposed exploration of the red planet in the lecture "Future Exploration of Mars." The Mars Global Surveyor, a long-term robotic exploration program from NASA, will go into orbit a year from now, scanning the planet's surface; the Mars Pathfinder will explore and create images of the planet's surface and monitor the weather. Sci-fi writers, boot up your laptops. The program begins at 7:30 p.m. at the Morrison Planetarium, California Academy of Sciences, Golden Gate Park. Admission is free-$7; call 750-7145.
