The SLS and Orion are rolled out to the launch pad for Artemis I mission

As part of preparations for launch, NASA moves Artemis 1 to Launch Complex 39B at the Kennedy Space Center. Orion and the rocket were about six and a half km from the launch pad on August 16. Here's the live stream.

A launch of the SLS rocket and Orion spacecraft is scheduled for no earlier than August 29 from the complex. It will be powered by five-segment boosters and four RS-25 engines, producing more than 3.9 million kilograms of thrust. 

As soon as the boosters, service module panels, and launch abort systems are jettisoned, along with the core stage engines being shut down, the core stage will separate from the spacecraft.

The spacecraft will deploy solar arrays after orbiting the earth. As a result of the Interim Cryogenic Propulsion Stage, Orion will be able to leave the Earth's orbit and travel in the direction of the moon shortly after that. 

Within two hours of launch, Orion will separate from the ICPS. ICPS will then deploy small satellites, known as CubeSats, including the BioSentinel, which will carry yeast to deep space. CubeSats will conduct many experiments and demonstrate the technology.

An ESA-built service module will propel Orion from Earth's orbit to the Moon. It is expected that the service module will supply the propulsion and power systems of the spacecraft. 

The module will also be used for storing air and water during future crewed missions. The spacecraft will stay in that orbit for approximately six days to collect data and assess its performance. 

As a result of this maneuver, Orion will once again come close to the moon's surface, about 95 kilometers from its surface, to accelerate back towards our planet using a precisely timed engine firing of the service module and the force of gravity emanating from the moon.

As Orion enters Earth's atmosphere at about 40,000 km/h, temperatures will approach 3,000°C. As it arrives at its destination after traveling more than 2 million miles and having spent about three weeks on a mission, the spacecraft should make a precision landing after a total of about three weeks.

As long as everything goes according to plan, the ship should be able to land within the eyesight of a recovery ship that will be stationed off the coast of Baja, California, on the night.

A small boat from the recovery ship can be used to approach and recover the spacecraft in small boats for some time until divers from the US Navy and team members from NASA's Exploration Ground Systems approach it in small boats. The divers will tow the capsule to the recovery ship after inspecting it.
