NASA has assembled the first of its powerful Space Launch System rockets (SLS), who will transport humans to the moon this decade

Friday, engineers at Kennedy Space Center in Florida finished lowering the center stage by 65 m (212 ft) high between two smaller booster rockets

This is the first time that the three key elements of the rocket have been brought together in their launch configuration

During this mission, known as Artemis-1, the SLS will carry Orion – the next generation American crew vehicle – towards the Moon However, no astronaut will be on board ; engineers want to test both the rocket and the spacecraft before humans are allowed to climb into 2023

The SLS consists of a giant central stage, which houses propellant tanks and four powerful engines, flanked by two 54 m powder thrusters (177 feet) de long (SERB) They provide most of the pushing force that propels the SLS off the ground during the first two minutes of flight.

The main stage and the SRBs are taller than the Statue of Liberty, minus its pedestal

Friday and Saturday, Kennedy Space Center crews used a lifting crane to first lift the center stage, transfer it from a horizontal position to a vertical position, then lower it into place between the SRBs on a structure called the mobile launcher

The mobile launcher provides access to the SLS for testing, inspection and maintenance It will also transfer the giant rocket to the launch pad

Meanwhile, the main stage was attached to a test bench in Mississippi, undergoing a comprehensive assessment program known as the Green Run

In March, the main stage engines were successfully fired for approximately eight minutes – the time taken by the SLS to get from ground to space – in the final and most important test of the green race.

Artemis-3, which will be the first mission to land humans on the Moon since Apollo 17 in 1972, expected to launch in the next few years NASA recently awarded the contract to build the next-generation lunar lander to SpaceX, who adapts the design of their spaceship for this purpose
