5. A Florida Early Morning, Launch Assembly Building (VAB) stands in it
The rocket and spacecraft are processed and assembled at the launch assembly building (VAB) prior to deployment on the launch tower. At VAB, upgrading of the dockyard area is under way to adjust the height of the basin quay to fit the SLS rockets' core level, which is assembled by NASA's Michuid Parts Assembly Plant in New Orleans Arrived at the AVB by a dedicated barge, it will be integrated with other hardware to prepare for the first launch of the SLS.

6. Used to lift Orion to launch the navel cranes and rigging
NASA installed several connections on mobile launchers, called the launch navel, which would connect to the SLS core and dual solid rocket propulsion, the temporary cryogenic propulsion and the Orion spacecraft. They will play a role in supplying energy, communications, cooling and fuel.

7. During the track test, a rainbow connects the VAB building in the distance with the crawler tractor
At the Kennedy Space Center (located in Florida), NASA's CT-2 tracks along the track to test the structural dynamics and load conditions of the recently upgraded track. The test was carried out to ensure that the track was well prepared for the first joint flight of the Orion spacecraft and SLS rockets.
At NASA's Kennedy Space Center (located in Florida), Crawler Tractor 2 (CT-2) is slowly moving down the track as it returns to the launch assembly building (as if in this background).

8. SLS engine section test object loading Pegasus barge
The SLS engine section structural qualification test object passed the Pegasus Barge and arrived at the NASA Marshall Space Flight Center (Huntsville, Alabama) by the Mittal Assembly Plant (New Orleans). Test objects were tested for structural loads. The electronically controlled hydraulic cylinder pushes, pulls, twists and tows the test object with millions of pounds of force to ensure that the hardware can withstand the extreme conditions of launch and lift. The engine section will house four RS-25 engines, mounted at the bottom of the rocket's core stage and attached as two solid rocket booster attachments.
At NASA's Machu Picchu plant in New Orleans, Pegasus barge is loaded with an engine section structural qualification test article designed to test NASA's new rocket SLS design.

9. Spacesuit vacuum pressure test
At the NASA Johnson Space Center in Houston, technicians stress-test aerospace suits to test the enhancements that astronauts can make on spaceships to be worn on Orion spacecraft. During this test, the spacesuit would be linked to a life support system, which would then evacuate the air from an 11-foot hot vacuum chamber, simulating a condition similar to that in the space capsule and assessing the performance of the spacesuit.
At NASA's Johnson Space Center in Houston, engineers and technologists are testing spacesuits and astronauts will take deep space travel on Orion spacecraft in this spacesuit.

15. Leave the spacecraft quickly
In the crew evacuation test in the Gulf of Mexico, the team evaluated each of the two modes of evacuation of crew members or aids separately. When the cabins fall into the sea, upside-down bags will be responsible for "knocking" Orion "over" if it is flipped upside down. At the NASA Johnson Space Center in Houston, the team also conducted a series of tests to assess how quickly those astronauts and ground crew involved in the final preparation stage before the launch of Orion's mission, if an emergency occurred prior to launch Leave the spacecraft.
July 10-14, waters off the coast of Galveston, Texas. A team of NASA and Defense researchers simulated a variety of scenarios to test the Orion's evacuation process.
