A redesigned hatch for an Apollo spacecraft is shown inside the new tribute to the crew of Apollo 1 who perished in a fire at the launch pad on Jan. 27, 1967, during training for the mission. Astronauts Gus Grissom, Ed White II and Roger Chaffee were lost during the fire. The tribute at the Apollo/Saturn V Center at NASA's Kennedy Space Center opened Jan. 27, 2017, 50 years after the crew of three was lost. It features numerous items recalling the lives of the three astronauts. The tribute also includes the three-part hatch to the spacecraft itself, the first time any part of the Apollo 1 spacecraft has been displayed publicly. The version of the hatch after it was redesigned was also showcased as an example of improvements NASA made throughout the agency and to the Apollo spacecraft that would later carry astronauts to the moon.
