11 a.m. in the Meijer Theater

Commander John Herrington, PhD, is a retired NASA astronaut, U.S. Navy Commander, and the first enrolled member of a Native American tribe (the Chickasaw Nation) to fly in space, During the 2002 STS-113 mission, where he served as a Mission Specialist, he performed three spacewalks focused on the International Space Station’s construction (these spacewalks are commemorated on the back of the 2019 version of the Sacagawea dollar). Herrington holds a PhD in education from the University of Idaho and a Master’s in aeronautical engineering from the Naval Postgraduate School. His service as a naval aviator, test pilot, and astronaut has earned him multiple awards and honors, including induction into both the Chickasaw and International Air & Space Halls of Fame. Dr. Herrington continues to share his experiences through public speaking and his children’s book, Mission to Space.

Community Involvement

We would love if you or your organization got involved in this stellar event! Sign up to join us on Saturday, February 15 with a demonstration, information, or activity table. We also welcome vendors for a small fee of $25. Help us inspire all ages to reach for the stars and get involved with STEAM.

Continue celebrating space exploration by visiting the GRPM’s Chaffee Planetarium. 

Shows in the Chaffee Planetarium take place every hour on February 17 and are $4 per person or $2 for Museum members. 

In addition to planetarium shows, the GRPM also partnered with astronaut Brent Bos and created a set of new interactive experiences outside of the Chaffee Planetarium. These include a lunar crater station, meteors under a microscope and a meteor pinball machine. 

The Planetarium lobby also features an exhibit with Roger B. Chaffee artifacts that tell a detailed story of his life.

Apollo 1 Tragedy

On January 27, 1967, tragedy struck NASA’s Apollo program when a flash fire occurred in command module 012 during a launch pad test of the Apollo/Saturn space vehicle being prepared for the first piloted flight, the AS-204 mission. Three astronauts, Lt. Col. Virgil I. Grissom, a veteran of Mercury and Gemini missions; Lt. Col. Edward H. White, the astronaut who had performed the first United States extravehicular activity during the Gemini program; and Grand Rapids Native Roger B. Chaffee, an astronaut preparing for his first space flight, died in this tragic accident.

The Grand Rapids Public Museum renamed its planetarium to the Roger B. Chaffee Planetarium the same year.

This event, scholarly in nature and open to the general public, is co-organized by the Grand Rapids Public Museum, Grand Valley State University, and the Roger B. Chaffee Scholarship Fund. Roger That! seeks to honor Chaffee and highlight local research in a two-day celebration of space exploration.
