Elmo and STS-135 Commander Chris Ferguson

"The crew of STS-135, NASA's final space shuttle mission, and Sesame Street's Elmo welcomed visitors to "What's Your Favorite Space?" in New York City. The free, public event was presented by NASA and Eventi on Wednesday, Aug. 17, from 10 a.m. until 4 p.m. on the hotel's "Big Screen Plaza." The outdoor plaza was transformed into a miniature space outpost filled with displays including an inflatable Mars Rover, demonstrations, interactive exhibits, video segments, children's activities and more. Pictured with Elmo is STS-135 Commander Chris Ferguson."
