KENNEDY SPACE CENTER, FLA. - Volunteers from the KSC Fire-Rescue team dressed in launch and entry suits settle into seats in an orbiter crew compartment mock-up under the guidance of George Brittingham, USA suit technician on the Closeout Crew. Brittingham is helping Catherine Di Biase, a nurse with Bionetics Life Sciences. They are all taking part in a “Mode VII” emergency landing simulation at Kennedy Space Center. The purpose is to exercise emergency preparedness personnel, equipment and facilities in rescuing astronauts from a downed orbiter and providing immediate medical attention. This simulation presents an orbiter that has crashed short of the Shuttle Landing Facility in a wooded area 2-1/2 miles south of Runway 33. Emergency crews will respond to the volunteer “astronauts” simulating various injuries. Rescuers must remove the crew, provide triage and transport to hospitals those who need further treatment. Local hospitals are participating in the exercise.

CAPE CANAVERAL, Fla. -- In the White Room at Launch Pad 39A at NASA's Kennedy Space Center in Florida, STS-135 Mission Specialist Rex Walheim prepares to board space shuttle Atlantis through the crew hatch in the background. Members of the Closeout Crew, in white uniforms, are there to assist astronauts with their launch-and-entry suits and the boarding process. Seen in the background is Mission Specialist Sandy Magnus speaking with a Closeout Crew member. The STS-135 crew is at the pad to participate in a launch countdown simulation exercise. As part of the Terminal Countdown Demonstration Test (TCDT), the crew members are strapped into their seats on Atlantis to practice the steps that will be taken on launch day. Shuttle Atlantis and its crew are targeted to lift off July 8, taking with them the Raffaello multi-purpose logistics module packed with supplies and spare parts to the International Space Station. The STS-135 mission also will fly a system to investigate the potential for robotically refueling existing satellites and return a failed ammonia pump module to help NASA better understand the failure mechanism and improve pump designs for future systems. STS-135 will be the 33rd flight of Atlantis, the 37th shuttle mission to the space station, and the 135th and final mission of NASA's Space Shuttle Program.

The outer end of the orbiter access arm ends in an environmental chamber (the White Room) that mates with the orbiter and allows personnel to enter the crew compartment. With assistance, each member of the flight crew dons a parachute pack before crawling through the open hatch into the shuttle. The closeout crew also straps the astronauts into the space shuttle's crew module and takes care of any other last-minute needs that arise. Space Shuttle Endeavour's STS-118 mission is the 22nd shuttle flight to the International Space Station. It will continue space station construction by delivering a third starboard truss segment, S5, and other payloads such as the SPACEHAB module and the external stowage platform 3. Liftoff of Endeavour is scheduled at 6:36 p.m. EDT. Photo credit: NASA/John Kechele, Scott Haun, Tom Farrar

KENNEDY SPACE CENTER, FLA. -- In the White Room on Launch Pad 39A, astronaut Clayton Anderson is helped by the closeout crew to secure his launch suit before climbing into Space Shuttle Atlantis. Anderson is flying to the International Space Station with the STS-117 crew to join the Expedition 15 crew on the space station. Flight Engineer Suni Williams will return to Earth in his place. The mission to the space station is scheduled to launch at 7:38 p.m. EDT. Members of the closeout crew help the astronauts don a parachute pack, strap them into the space shuttle's crew module and take care of any other last-minute needs that arise. The White Room is at the end of the orbiter access arm that extends from the fixed service structure and provides entry into the orbiter. The shuttle is delivering a new segment to the starboard side of the space station's backbone, known as the truss. Three spacewalks are planned to install the S3/S4 truss segment, deploy a set of solar arrays and prepare them for operation. STS-117 is the 118th space shuttle flight, the 21st flight to the station, the 28th flight for Atlantis and the first of four flights planned for 2007. Photo credit: NASA/Tony Gray & Don Kight

CAPE CANAVERAL, Fla. -- In the White Room at Launch Pad 39A at NASA's Kennedy Space Center in Florida, STS-135 Mission Specialists Rex Walheim and Sandy Magnus enjoy a light moment with the Closeout Crew before boarding space shuttle Atlantis through the crew hatch in the background. Members of the Closeout Crew, in white uniforms, are there to assist astronauts with their launch-and-entry suits and the boarding process. Seen in the background is Mission Specialist Sandy Magnus speaking with a Closeout Crew member. The STS-135 crew is at the pad to participate in a launch countdown simulation exercise. As part of the Terminal Countdown Demonstration Test (TCDT), the crew members are strapped into their seats on Atlantis to practice the steps that will be taken on launch day. Shuttle Atlantis and its crew are targeted to lift off July 8, taking with them the Raffaello multi-purpose logistics module packed with supplies and spare parts to the International Space Station. The STS-135 mission also will fly a system to investigate the potential for robotically refueling existing satellites and return a failed ammonia pump module to help NASA better understand the failure mechanism and improve pump designs for future systems. STS-135 will be the 33rd flight of Atlantis, the 37th shuttle mission to the space station, and the 135th and final mission of NASA's Space Shuttle Program.

CAPE CANAVERAL, Fla. -- In the Multi-Payload Processing Facility at NASA's Kennedy Space Center in Florida, workers take photos and video of fire and rescue personnel, as well as a closeout crew, participating in an exercise known as crew egress evaluation from an Orion mock-up. The spacecraft is replicated in all areas that could affect a crew's escape, including the area that seals to a launch pad's White Room. The exercise focuses on whether astronauts and their rescue crews can exit the vehicle quickly in the event of a pad emergency. For more information on Orion, visit www.nasa.gov/orion.

KENNEDY SPACE CENTER, FLA. - At the KSC Launch Pad 39A, two members of the payload closeout crew check equipment as the doors are just about ready to be closed. The Payload inside the bay of Discovery, the orbiter for the STS-82 mission, is ready for the launch of the second Hubble Space Telescope service mission. The payload consists of the Near Infrared Camera and Multi-Object Spectrometer (NICMOS) that will be installed, Fine Guidance Sensor #1 (FGS-1), and the Space Telescope Imaging Spectrograph (STIS) to be installed. The STS-82 will launch with a crew of seven at 3:54 a.m. EST, Feb. 11, 1997. The launch window is 65 minutes in duration. The Mission Commander for STS-82 is Ken Bowersox. The purpose of the mission is to upgrade the scientific capabilities, service or replace aging components on the Telescope and provide a reboost to the optimum altitude.

Teams at NASA’s Kennedy Space Center in Florida practice the Artemis mission emergency escape or egress procedures during a series of integrated system verification and validation tests at Launch Pad 39B on Sunday, Aug. 11, 2024. Members of the closeout crew, simulated flight crew, pad rescue team, and the Exploration Ground Systems Program practiced the process of getting inside and out of the emergency egress baskets. While the crew and other personnel will ride the emergency egress baskets to the terminus area in a real emergency, no one rode the baskets for this test. Instead, teams tested the baskets during separate occasions by using water tanks filled to different levels to replicate simulate the weight of passengers.
