Fifth grade students from Stuart Roosa Elementary had a field trip that was out of this world Thursday as they celebrated Stuart Roosa Day.

Splitting into three groups, students went the the Claremore Museum of History and downtown to see the mural.

At the museum, students decorated star charts, watched videos about Roosa’s life and career and spoke with former aerospace technology quality assurance inspector Ron Strothmann.

Students learned that Roosa was one of only 24 astronauts to have ever visited the moon, and that his mission involved taking seedlings to the surface and returning them to earth to see if space travel affected their growth. Roosa’s moon trees are still growing on earth today.

From there students walked to the mural, downtown, and stared up in wonder at the vibrant, larger-than-life portrait of Roosa.

They met with the artist, John Hammer, who answered all their questions and encouraged them to pursue their passions.

“No matter where you are from, you can do what you want. You can even go to the moon,” he said.

Hammer is donating a smaller version of the Roosa painting to the Museum of History.
