During rollout operations for NASA’s Artemis I Moon rocket, the iconic Vehicle Assembly Building is visible in the background behind the countdown clock at Kennedy Space Center in Florida, Tuesday, Aug. 16, 2022. As part of the agency’s Artemis I flight test, the fully stacked and integrated Space Launch System (SLS) rocket with the Orion spacecraft is scheduled to liftoff on Monday, Aug. 29. The first in a series of increasingly complex missions, Artemis I will provide a foundation for human deep space exploration and demonstrate our commitment and capability to extend human presence to the Moon and beyond. The primary goal of Artemis I is to thoroughly test the integrated systems before crewed missions by launching Orion atop the SLS rocket, operating the spacecraft in a deep space environment, testing Orion’s heat shield, and recovering the crew module after reentry, descent, and splashdown.

KENNEDY SPACE CENTER, FLA. -- Apollo 10 rollout to Complex 39-B.

NASA’s Space Launch System and Orion spacecraft atop the mobile launcher are in view in High Bay 3 of the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida on Tuesday, Aug. 16, 2022. All of the work platforms have been retracted in preparation for rollout to Launch Complex 39B ahead of launch of Artemis I. The crawler-transporter, driven by engineers, is under the Artemis I stack atop the mobile launcher and will carry it 4.2 miles via the crawlerway that connects the VAB to the launch pad. The agency’s Artemis I flight test is scheduled to liftoff on Monday, Aug. 29. The first in a series of increasingly complex missions, Artemis I will provide a foundation for human deep space exploration and demonstrate our commitment and capability to extend human presence to the Moon and beyond.

KENNEDY SPACE CENTER, FLA. - Robert T. Nelson of KSC Security points to an approximately 24-foot-long crack on the Mobile Launcher Platform (MLP), which is holding the Space Shuttle Discovery en route to Launch Pad 39A for the STS-82 mission. Nelson was riding on the MLP when he heard a loud noise and noticed the crack. Rollout had begun shortly after 7 a.m. EST and was stopped at about 8:25 a.m. This Y-shaped crack is on the MLP surface and runs from near the left-hand solid rocket booster flame hole toward the near corner of the MLP. Rollout of Discovery resumed just past noon after structural engineers determined that the integrity of the MLP had not been compromised. Discovery is scheduled to lift off on the second Hubble Space Telescope servicing mission on Feb. 11.

KENNEDY SPACE CENTER, FLA. - Like candles embedded in a sculptured “cake,” the Mobile Launcher Platform (MLP) number 3 with twin solid rocket boosters bolted to it inches along the crawlerway at various speeds up to 1 mph in an effort to achieve vibration data gathering goals. The boosters are braced at the top for stability. The primary purpose of these rollout tests is to gather data to develop future maintenance requirements on the transport equipment and the flight hardware. Various parts of the MLP and crawler transporter have been instrumented with vibration data collection equipment.

KENNEDY SPACE CENTER, FLA. -- After Endeavour’s rollout from inside the Orbiter Processing Facility, the transporter (foreground) prepares to tow it to the Vehicle Assembly Building for temporary transfer. A protective cover surrounds the nose of Endeavour. The move to the VAB allows work to be performed in the OPF that can only be accomplished while the bay is empty. Work scheduled in the OPF includes annual validation of the bay’s cranes, work platforms, lifting mechanisms and jack stands. Endeavour will remain in the VAB for approximately 12 days, then return to the OPF.

CAPE CANAVERAL, Fla. – Space shuttle Atlantis stands ready in the Vehicle Assembly Building at NASA’s Kennedy Space Center for the pending rollout to Launch Pad 39A. The Sept. 2 rollout date was postponed due to Tropical Storm Hanna’s shift to a northern track. Managers are closely following Hanna to determine when would be the best time this week to move space shuttle Atlantis to its launch pad. The tentative rollout time is 10 a.m. Sept. 4, depending on the track Hanna follows along the Florida coast. Atlantis is scheduled to launch on the STS-125 mission to service NASA’s Hubble Space Telescope. Launch is targeted for Oct. 8. Photo credit: NASA/Jack Pfaller

KENNEDY SPACE CENTER, FLA. -- Space Shuttle Program Director Wayne Hale talks to reporters about the rollout of Space Shuttle Discovery to Launch Pad 39B. First motion from NASA's Vehicle Assembly Building was at 12:45 p.m. EDT. The rollout is an important step before launch of Discovery on mission STS-121 to the International Space Station. Discovery's launch is targeted for July 1 in a launch window that extends to July 19. During the 12-day mission, Discovery's crew will test new hardware and techniques to improve shuttle safety, as well as deliver supplies and make repairs to the station.

KENNEDY SPACE CENTER, FLA. -- After an early morning rollout, Space Shuttle Atlantis sits on the launch pad. The Rotating Service Structure is wide open (at left). After being stacked with its solid rocket boosters and external tank, Atlantis began its rollout to Launch Pad 39B at 2:27 a.m. EDT in preparation for launch to the International Space Station. The Shuttle arrived at the Pad and was hard down at 9:38 a.m. Launch is scheduled no earlier than Oct. 2 for mission STS-112, the 15th assembly flight to the International Space Station. Atlantis will carry the S1 Integrated Truss Structure, which will be attached to the central truss segment, the S0 truss, during the mission.
