STS114-E-5282 (28 July 2005) --- This frame and STS114-E-5283 actually can be conjoined and rotated 90 degrees to make a single frame, providing an "astronaut's eye view" from Discovery's aft cabin looking toward the recently docked International Space Station. At the left side are the S0 truss and mobile transporter, with the P6 truss on the right side.

The Space Shuttle Atlantis, STS-110 mission, deployed this railcar, called the Mobile Transporter, and an initial 43-foot section of track, the S0 (S-zero) truss, preparing the International Space Station (ISS) for future spacewalks. The first railroad in space, the Mobile Transporter will allow the Station's robotic arm to travel up and down the finished truss for future assembly and maintenance. The 27,000-pound S0 truss is the first of 9 segments that will make up the Station's external framework that will eventually stretch 356 feet (109 meters), or approximately the length of a football field. The completed truss structure will hold solar arrays and radiators to provide power and cooling for additional international research laboratories from Japan and Europe that will be attached to the Station. The Space Shuttle Orbiter Atlantis, STS-110 mission, was launched April 8, 2002 and returned to Earth April 19, 2002. STS-110's Extravehicular Activity (EVA) marked the first use of the Station's robotic arm to maneuver spacewalkers around the Station.

Backdropped against the blackness of space and the Earth's horizon, the S0 (S-zero) truss is removed from Atlantis' cargo bay and onto the Destiny laboratory of the International Space Station (ISS) by Astronauts Ellen Ochoa, STS-110 mission specialist, and Daniel W. Bursch, Expedition Four flight engineer, using the ISS' Canadarm2. Space Shuttle Orbiter Atlantis, STS-110 mission, prepared the International Space Station (ISS) for future spacewalks by installing and outfitting the 43-foot-long S0 truss and preparing the first railroad in space, the Mobile Transporter. The 27,000-pound S0 truss was the first of 9 segments that will make up the Station's external framework that will eventually stretch 356 feet (109 meters), or approximately the length of a football field. This central truss segment also includes a flatcar called the Mobile Transporter and rails that will become the first "space railroad," which will allow the Station's robotic arm to travel up and down the finished truss for future assembly and maintenance. The completed truss structure will hold solar arrays and radiators to provide power and cooling for additional international research laboratories from Japan and Europe that will be attached to the Station. Milestones of the STS-110 mission included the first use of the Station's robotic arm to maneuver spacewalkers around the Station and it was the first time all of a Shuttle crew's spacewalks were based out of the Station's Quest Airlock. It was also the first Shuttle to use three Block II Main Engines. The Space Shuttle Orbiter Atlantis, STS-110 mission, was launched April 8, 2002 and returned to Earth April 19, 2002.

A photo of NASA’s crawler-transporter 2 odometer on Wednesday, Sept. 25, 2024, at NASA’s Kennedy Space Center in Florida, commemorates the milestone of reaching 2,500 miles traveled since its construction in 1965. Crawler-transporter 2’s original odometer ceased working in 1977 at 644 miles, so teams with NASA’s Exploration Ground Systems added the original figure to the new odometer to calculate the milestone. Built originally to transport massive Saturn V rockets during the Apollo Program, crawler-transporter 2 continued its service during the Space Shuttle Program, and currently transports the massive SLS (Space Launch System) rocket and Orion spacecraft atop the mobile launcher as part of the agency’s Artemis campaign.

A close-up view of the treads on crawler-transporter 2 (CT-2) as the behemoth vehicle moves along the crawlerway at NASA’s Kennedy Space Center in Florida on Jan. 22, 2021. Teams are working to ensure the crawlerway, the path the CT-2, mobile launcher, and Space Launch System rocket with Orion atop will take from the Vehicle Assembly Building to Launch Complex 39B, is strong enough to withstand the weight and provide stability for the Artemis I mission. CT-2 carrying mobile launcher platform 1, used during the shuttle program, was driven back and forth on the crawlerway with several cement blocks, each weighing about 40,000 pounds to strengthen the crawlerway for launch. Artemis I will be the first in a series of increasingly complex missions to the Moon. Under the Artemis program, NASA aims to land the first woman and the next man on the Moon in 2024 and establish sustainable lunar exploration by the end of the decade.

STS-110 Mission astronaut Rex J. Walheim, accompanied by astronaut Steven L. Smith (out of frame) translates along the Destiny laboratory on the International Space Station (ISS) during the third scheduled EVA session. The duo released the locking bolts on the Mobile Transporter and rewired the Station's robotic arm. The STS-110 mission prepared the ISS for future space walks by installing and outfitting the S0 (S-Zero) Truss and the Mobile Transporter. The 43-foot-long S0 truss weighing in at 27,000 pounds was the first of 9 segments that will make up the Station's external framework that will eventually stretch 356 feet (109 meters), or approximately the length of a football field. This central truss segment also includes a flatcar called the Mobile Transporter and rails that will become the first "space railroad," which will allow the Station's robotic arm to travel up and down the finished truss for future assembly and maintenance. The completed truss structure will hold solar arrays and radiators to provide power and cooling for additional international research laboratories from Japan and Europe that will be attached to the Station. Milestones of the S-110 mission included the first time the ISS robotic arm was used to maneuver space walkers around the Station and marked the first time all space walks were based out of the Station's Quest Airlock. It was also the first Shuttle to use three Block II Main Engines. The Space Shuttle Orbiter Atlantis, STS-110 mission, was launched April 8, 2002 and returned to Earth April 19, 2002.

The nearly 400-foot-tall mobile launcher was at the pad for 10 days, while engineers with Exploration Ground Systems and Jacobs performed several tasks, including a timing test to validate the launch team’s countdown timeline, and a thorough, top-to-bottom wash down of the mobile launcher to remove any debris remaining from construction and installation of the umbilical arms. Artemis I will test the Orion spacecraft and Space Launch System as an integrated system ahead of crewed flights to the Moon. Under the Artemis program, NASA will land the first woman and the next man on the Moon in 2024.
