The New Mexico Museum of Space History is honored to host the community’s annual 9.11 Memorial Stair Climb in conjunction with the City of Alamogordo Fire Department and area first responders. Teams of up to four participants climb the equivalent of the 110 stories of the World Trade Center in tribute to the fallen heroes of Sept. 11. Firefighters and first responders from across the region are expected to participate. The general public is invited to join the stair climb. One complete circuit – the equivalent of the 110 stories of the World Trade Center – is approximately 11 and a half trips up the stairs of the museum, across the fifth floor, and then down the stairs on the other side. Medical personnel will be onsite during the event.
