Explore Space Science From Impact to Exploration!
Saturday, June 27, 2026
Join us at Meteor Crater and Lowell Observatory for a full day celebrating Asteroid Day alongside Apollo 9 astronaut Rusty Schweickart, joined by fellow NASA astronauts Steve Smith, Nicole Stott, Ed Lu, and renowned science communicator Scott Manley.
Asteroid Day is an international event commemorating the 1908 Tunguska event, the largest recorded asteroid impact in modern history. Each year, scientists, astronauts, and space communicators gather at Meteor Crater to share discoveries and inspire curiosity about planetary defense and our solar system.
This year’s program will feature astronaut presentations and photo opps, guided crater experiences, special talks and family friendly activities. Guest speakers are made possible through the generous support of the B612 Foundation.
