The first Artemis is gone. The SLS rocket left Earth, launching the Orion capsule toward the moon


At 7:47 Italian time, on November 16, the Space Launch System (SLS) rocket of the Artemis I mission, which will allow the unmanned Orion capsule to reach the moon, was finally able to lift off from the Kennedy Space Center.

The actual departure was delayed by about 40 minutes compared to the time estimated by NASA because it was during the night However, NASA engineers had to stop the intermittent leakage of liquid hydrogen In the tanks of the primary stage, i.e. the main stage. The Red Intervention Team solved it Kennedy Space Center.

There was also an unexpected problem with the US Space Force’s eastern range, which is responsible for the overall safety of all launches from the Florida Space Coast: A faulty ethernet switch temporarily caused one of its radar sites to lose signal. Essential launch safety cover if the missile goes off course.

Artemis I has finally begun

However, NASA managed to solve the unexpected and launch the SLS rocket. Two minutes after launch, the two solid-propellant side thrusters separated, leaving the task of thrusting the four primary RS-25 stage engines already in use on shuttle missions. These are four engines that have already completed 3 to 12 flights behind them.

8 minutes after launch, the Core Stage also completed its mission, separating from the second stage consisting of the Orion shuttle and its associated ICPS module.

Orion then opened its solar arrays, after which the ICPS module ignited its rockets to achieve their desired trajectory. At this point, the ten Cube satellites will also be launched for the parallel missions of Artemis I; Among these there is also the Italian Argomoon which will have the mission of external observation to separate the ICPS module from OrionExpected approximately two hours after launch.

Artemis I’s mission will last for 26 days. Orion will orbit the Moon and then return to Earth by crashing into the Pacific Ocean to test its heat shield.

Update 11/16: Fix for ICPS module missiles firing after Orion’s solar panels are unlocked and not before.
