Six-year-old Ollie Tyrrell knows all about Christa McAuliffe. He hopes to be an astronaut someday and frequently visits the planetarium at the McAuliffe-Shepard Discovery Center in Concord.

When his mom, Danielle Vincent, heard a statue of McAuliffe, the widely beloved Concord teacher who died on the Challenger space shuttle 38 years ago, would be unveiled at the State House grounds, she knew she had to take him along. Tyrrell and his siblings were decked out in NASA spacesuit costumes as they waited on a picnic blanket near the statue.

They weren’t alone. About 500 people gathered in Concord on Monday to see McAuliffe’s likeness unveiled on what would’ve been her 76th birthday. Now, she’s memorialized on the New Hampshire State House lawn – the first woman to ever receive the honor.

McAuliffe taught social studies at Concord High School and was the first citizen to go into space. She died alongside six others in the Challenger when it exploded on Jan. 28, 1986, just 73 seconds after takeoff. Before the launch, McAuliffe’s presence on the shuttle had drawn excitement across the nation – many who attended the unveiling said they remember exactly where they were when they saw the tragedy live on TV. She was survived by her husband, Steven McAuliffe, and her two children, Scott and Caroline, who were 9 and 6 years old at the time.

Created by sculptor Benjamin Victor, the 8-foot-tall bronze statue depicts McAuliffe in motion, walking like she did aboard the platform to the shuttle. She’s smiling and dressed in her spacesuit. The statue is placed on a granite pedestal, with her name in raised letters and informational plaques.

On one side is her motto: “I touch the future; I teach.”

Victor, like many people, remembers where he was when the Challenger exploded. Then a young student, his teachers wheeled the big television into his classroom to watch the takeoff. He didn’t truly understand what had happened until it was explained to him.

“There’s a silver lining in all of this, and that’s what we’re here to celebrate today. That is that her lesson is continually taught,” Victor said. “That lesson of inspiration hasn’t been lost in the disaster, and her memory will go on forever.”

Gov. Chris Sununu was in fourth grade when McAuliffe was selected for NASA’s Teacher in Space Project. As he saw her on television, training for a year to go on the Challenger and teach the first class in space, Sununu recalled realizing that as a Granite Stater and a teacher, she was “one of us.”

“She was just larger than life,” Sununu said, “but she was just down the road.”

He established the Christa McAuliffe State House Memorial Commission via an executive order last February. Now, when kids come to tour the Capitol, Sununu said, they’ll be able to walk right up and see Concord’s “hero teacher.”

Steven, Christa’s husband and a judge for the New Hampshire District Court who now lives in New London, described his wife as an amazing teacher and a happy person with a contagious laugh. He remembers her helping students outside the classroom, too – she housed students sometimes if things were bad for them at home. One day, Steven mentioned the potential liability that could incur.

Her response? “So sue me.”

Christa was “thrilled” when she got selected for the NASA program, he said, but the celebrity that came with it never changed her. She always viewed herself as a regular person who’d been given an incredible opportunity.

“That opportunity, of course, included training for and flying in the space shuttle, which she was over the moon about,” Steven said. “But, there was another part of this opportunity that meant far more to her – the opportunity to represent her fellow teachers, to play an effective national role in focusing the public’s attention on and fostering public appreciation for the critical role that teachers play, not only in educating our children but also in teaching them to be honorable, ethical and informed citizens.”

Kristin Jacques, a student of Christa’s, now teaches fifth grade in Hopkinton. She remembers Christa greeting students at her classroom door every day and said she didn’t just lecture students – she engaged with them. During the year leading up to takeoff, Christa took a sabbatical to train for the mission but returned every now and then to Concord High School to tell them all about her travels, training and experiences. She still wrote college recommendations and did other things for her students during her time away, Jacques said.

“She didn’t just teach us about the world. She taught us how to be part of it,” Jacques said. “Thank you, Mrs. McAuliffe, for all you gave us. Your legacy will live on, not just in bronze, but in the countless lives that you touched.”

If anything, Monday’s crowd was a testament to that.

A current student at Maple Street School in Hopkinton, Nathaniel Dunlap, won an essay contest commemorating Christa and read his paper to the crowd. He looks up to Christa, he said, because she was an inspiring educator and seized new opportunities.

“She achieved what was thought impossible,” Dunlap said. “She has motivated me to look out for all opportunities and take them. If life looks like it’s going one way or another, keep an eye out so that change is still possible. It has inspired me to try and be the best I can be as a person.”
