The 2017 class of astronaut candidates are inside the Space Station Processing Facility high bay during a familiarization tour of facilities at NASA's Kennedy Space Center in Florida. They are viewing the Interim Cryogenic Propulsion System for NASA's Space Launch System rocket. The candidates toured center facilities, including the Neil Armstrong Operations and Checkout Building high bay; the Launch Control Center, Launch Pad 39B, and the Vehicle Assembly Building. They also toured Boeing's Commercial Crew and Cargo Facility, United Launch Alliance's Space Launch Complex 41 at Cape Canaveral Air Force Station, and SpaceX's Launch Pad 39A at Kennedy. The candidates will spend about two years getting to know the space station systems and learning how to spacewalk, speak Russian, control the International Space Station's robotic arm and fly T-38s, before they're eligible to be assigned to a mission.

The HOST (the Hubble Space Telescope Orbital Systems Test) payload is moved into the high bay of the Space Station Processing Facility (SSPF). HOST is scheduled to fly on the STS-95 mission, planned for launch on Oct. 29, 1998. The mission includes other research payloads such as the Spartan solar-observing deployable spacecraft, the International Extreme Ultraviolet Hitchhiker, as well as the SPACEHAB single module with experiments on space flight and the aging process

Inside the Space Station Processing Facility high bay at NASA's Kennedy Space Center in Florida, a set of International Space Station Roll Out Solar Arrays (iROSA) have been secured onto a platform on March 23, 2023. They are being prepared for delivery to the space station aboard SpaceX’s Dragon cargo carrier on the company’s 28th commercial resupply services (CRS-28) mission to the space station. iROSA is a new type of solar panel that rolls open in space and is more compact than current rigid panel designs.

In the Space Station Processing Facility high bay at NASA's Kennedy Space Center in Florida, technicians are preparing Orbital ATK's CYGNUS pressurized cargo module for bagging. The Orbital ATK CRS-7 commercial resupply services mission to the International Space Station is scheduled to launch atop a United Launch Alliance Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station on March 19, 2017. CYGNUS will deliver thousands of pounds of supplies, equipment and scientific research materials to the space station.

CAPE CANAVERAL, Fla. – Engineers lift the top off a shipping container to reveal NASA's TDRS-L satellite inside the high bay at the Astrotech payload processing facility in Titusville for launch processing. The TDRS is the latest spacecraft destined for the agency's constellation of communications satellites that allows nearly continuous contact with orbiting spacecraft ranging from the International Space Station and Hubble Space Telescope to the array of scientific observatories.

United Launch Alliance (ULA) president and CEO Tory Bruno, left, leads a tour for Vice President Mike Pence on Feb. 20, 2018. They are in the ULA Horizontal Integration Facility (HIF), at Cape Canaveral Air Force Station in Florida. The HIF is where the Delta IV Heavy boosters are being processed for NASA’s upcoming Parker Solar Probe mission. During his visit, Pence will chair a meeting of the National Space Council on Feb. 21, 2018 in the high bay of NASA Kennedy Space Center’s Space Station Processing Facility. The council's role is to advise the president regarding national space policy and strategy, and review the nation's long-range goals for space activities.

The Orion stage adapter for Artemis 1 is in view, wrapped in a protective covering, in this photograph taken on May 16, 2019, inside the high bay in the Space Station Processing Facility (SSPF) at NASA's Kennedy Space Center in Florida. The center is celebrating the SSPF’s 25th anniversary. The facility was built to process elements for the International Space Station. Now it is providing support for current and future NASA and commercial provider programs, including Commercial Resupply Services, Artemis 1, sending the first woman and next man to the Moon, and deep space destinations including Mars.

KENNEDY SPACE CENTER, FLA. - In the Vehicle Assembly Building (VAB), Space Shuttle Atlantis is positioned horizontally as it is lowered into the transfer aisle. The vehicle was just demated from its External Tank_Solid Rocket Booster stack in one of the VAB's high bays. The orbiter will be rolled back to Orbiter Processing Facility bay 1 where processing will begin for mission STS-115, the 19th flight to the International Space Station. The tank, ET-120, is the first redesigned ET to arrive at KSC and will undergo further testing before Return to Flight mission STS-121 next year.

An Integrated Equipment Assembly (IEA) is moved into the center of the Space Station Processing Facility clean room at KSC for transition to the high bay. The IEA, a large truss segment of the International Space Station (ISS), is one of four power modules to be used on the International Space Station. The modules contain batteries for the ISS solar panels and power for the life support systems and experiments that will be conducted. This first IEA will fly on the Space Shuttle Endeavour as part of STS-97, scheduled to launch August 5, 1999

Senior leaders with Kennedy Space Center in Florida, familiarize newly appointed officials from NASA Headquarters with the center’s facilities during a tour on April 19, 2021. The group views Sierra Nevada’s Large Inflatable Fabric Environment (LIFE) habitat inside the Space Station Processing Facility high bay. The habitat is an expandable habitat. Expandable habitats have the benefit of greatly decreasing the amount of volume it takes to launch the habitat, which can then inflate once it is in space.

Technicians use a Hyster forklift to move the Multiple User System for Earth Sensing, or MUSES, payload out of the Space Station Processing Facility high bay at NASA's Kennedy Space Center in Florida. MUSES will be delivered to the International Space Station aboard the SpaceX Dragon cargo carrier on the company’s 11th commercial resupply services mission to the space station. MUSES, developed by Teledyne Brown, is part of the company's new commercial space-based digital imaging business. MUSES hosts earth-viewing instruments, such as high-resolution digital cameras, hyperspectral imagers, and provides precision pointing and other accommodations.
