This photograph depicts the Saturn V vehicle (SA-501) for the Apollo 4 mission in the Vehicle Assembly Building (VAB) at the Kennedy Space Center (KSC). After the completion of the assembly operation, the work platform was retracted and the vehicle was readied to rollout from the VAB to the launch pad. The Apollo 4 mission was the first launch of the Saturn V launch vehicle. Objectives of the unmanned Apollo 4 test flight were to obtain flight information on launch vehicle and spacecraft structural integrity and compatibility, flight loads, stage separation, and subsystems operation including testing of restart of the S-IVB stage, and to evaluate the Apollo command module heat shield. The Apollo 4 was launched on November 9, 1967 from KSC.

This photograph was taken during the final assembly operation of the Saturn V launch vehicle for the Apollo 4 (SA 501) mission. The instrument unit (IU) was mated atop the S-IC/S-II assembly in the Vehicle Assembly Building high bay at the Kennedy Space Center.

Objectives of the unmanned Apollo 4 test flight were to obtain flight information on launch vehicle and spacecraft structural integrity and compatibility, flight loads, stage separation, and subsystems operation including testing of restart of the S-IVB stage, and to evaluate the Apollo command module heat shield. The Apollo 4 was launched on November 9, 1967 from KSC.

Armstrong Operations and Checkout Building during Crew-4 dry dress rehearsal on April 20, 2022. Cristoforetti, along with fellow Crew-4 astronauts Kjell Lindgren, Bob Hines, and Jessica Watkins, is scheduled to lift off from Kennedy’s Launch Complex 39A at 5:26 a.m. EDT on April 23, 2022. SpaceX’s Falcon 9 rocket and Crew Dragon, named Freedom by the Crew-4 crew, will launch the astronauts to the International Space Station as part of NASA’s Commercial Crew Program.

CAPE CANAVERAL, Fla. – The Vehicle Assembly Building, Launch Control Center and Mobile Launcher are in this view of the Launch Complex 39 area at NASA's Kennedy Space Center in Florida. Inside the Launch Control Center, the Ground Systems Development and Operations Program is overseeing efforts to create a new firing room based on a multi-user concept in Firing Room 4. The design of Firing Room 4 will incorporate five control room areas that are flexible to meet current and future NASA and commercial user requirements. The equipment and most of the consoles from Firing Room 4 were moved to Firing Room 2 for possible future reuse. Photo credit: NASA/Ben Smegelsky
