Starship Reality-check – Apr 16

The stars beckon. But humans evolved to survive on Earth, not to hurtle through space. For long-duration travel — interplanetary and, even, interstellar — what spacecraft accommodations are necessary? Is on-board human hibernation an option? Might we overcome the problems of space radiation and prolonged weightlessness? Finally, scientists may argue that the ideal craft for fast human interstellar travel is the "1-g starship" (perhaps similar to the Bussard Ramjet, artist's impression above), but what do the engineers say?

Our two speakers are Dr. Pascal Lee, Planetary Scientist at the SETI Institute and the Mars Institute, and Tucker Hiatt, Director of Wonderfest. This will be the first monthly event of 2022's Mt Tam Astronomy Program (MTAP). Consult "How" text, below, for access and parking information.

Our two speakers are Dr. Pascal Lee, Planetary Scientist at the SETI Institute and the Mars Institute, and Tucker Hiatt, Director of Wonderfest. This will be the first monthly event of 2022's Mt Tam Astronomy Program (MTAP). Consult "How" text, below, for access and parking information.

Location: Cushing "Mountain" Amphitheater, Pan Toll Road at Ridgecrest Blvd., Mt Tamalpais State Park
HOW:

Mt. Tamalpais State Park closes at sunset; on April 16th, that's ~ 7:45pm. Only vehicles with an Astronomy Program parking pass will be admitted thereafter:

  •    Print a FREE MTAP parking pass NOT YET at this Eventbrite website.
  •    After sunset, vehicles lacking a parking pass may be cited.
  •    Vehicles can exit the Park until 10:00pm; after that, remaining vehicles may be cited.

This event is presented, admission-free, by Wonderfest, the Friends of Mount Tam, the San Francisco Amateur Astronomers (SFAA). Optional SFAA sky tour and telescope viewing will follow the lecture.

Bring a flashlight and — even though mountaintop weather (above the fog) can be warmer than down at sea level — wear warm clothes in layers. If rain or wildfire threatens, call 415-455-5370 after 3:30pm on event day to learn about event status.
