COLUMBUS — John Glenn is continuing to inspire 55 years after becoming the first American to orbit Earth.

Since Mr. Glenn’s death on Dec. 8 at the age of 95, untold numbers of devotees have stopped by an exhibit of his artifacts on the campus of Ohio State University, backers have begun fund-raising for an observatory and astronomy park in Mr. Glenn’s name and work has begun on a 7-foot statue in his likeness.

While he also spent time as a military test pilot and U.S. senator, it was the history-making Mercury mission that propelled Mr. Glenn and his spacecraft Friendship 7 into the history books. Monday marked the anniversary of the flight.

For 4 hours, 55 minutes, and 23 seconds on Feb. 20, 1962, the capsule circled the Earth three times, making Mr. Glenn the first American to orbit Earth.

Jeffrey Thomas, an archivist at Ohio State who curated the Glenn display on display until March, said the event was so intensely anticipated and followed by the public that it made Mr. Glenn an instant hero.

He said the world knew debris from a burning heat shield was flying by Mr. Glenn’s window as he entered the atmosphere and into radio silence.

“So, here he goes into the atmosphere and everything’s black for 10 minutes,” Mr. Thomas said. “Did he make it? Did he burn up?”

Mr. Glenn was fine, and he went on to a long life remembered in the display. Among items displayed are his baby book, his first pilot’s license, flight logs, personal notes, anti-aircraft shell fragments recovered from a jet fighter-bomber he flew during the Korean War, patches, jackets, medals, and headgear.

The walls of artist Zenos Frudakis’ studio in eastern Pennsylvania are also plastered with photos of Mr. Glenn, as the sculptor produces clay models for an eventual full-size sculpture.

Mr. Frudakis has connected with Adam Sackowitz, a New York graduate student pursuing a sculpture, portrait, and other tangible remembrances of Mr. Glenn. An initial application seeking a spot on the Historic Register for Mr. Glenn’s birthplace was rejected. The National Park Service has indicated Mr. Glenn’s boyhood home in New Concord is more suitable for the designation.

The Ohio History Connection, the state history office, has not yet received initial paperwork on the boyhood home, said spokeswoman Emmy Beach.

Mr. Glenn’s legacy is also inspiring members of the nonprofit Friends of Hocking Hills State Park.

The group has secured half of the $1.6 million budget to build an observatory and astronomy park at the location about 45 miles southeast of Columbus. A lack of light pollution in the area allows clear views of the night sky, the group says.

Mr. Frudakis’ business partner said fundraising efforts are also underway for the sculpture project, which will exceed six figures.
