Three of the astronauts from the Shuttle Discovery's maiden voyage were at the Cosmosphere on Saturday, Aug. 22, to commemorate its 25 year anniversary.
Charlie Walker, Hank Hartsfield and Steve Hawley spoke to a large group about the mission and the craft. They shared stories of what was happening behind the scenes too, including how the mission patch was designed.
After the speech they signed autographs and met the public before attending a private reception for premium members only.
