How the Artemis 1 mission to the moon will unfold

This is the first time launcher SLS (space launch system) show yourself fully to the public Cape Canaveral. accompanied by full moon, the SLS dominates the historic launch site as it slowly progresses toward Pad 39B.It reminded observers and an entire generation of the path the Saturn V took towards the same launch pad prior to launch astronaut exist moon. is a critical step NASA who succeeded SLS lunar rocket glides. Now what’s the next step?

SLS has reached its launch pad, what now?

We now have to check if the SLS fits well into its launchpad. NASA has scheduled a rehearsal for early April. An exact date has not yet been communicated. In this comprehensive exercise, a test to fill the SLS fuel tank was specifically included. to take off, Rocket Lunar calendar will consumeoxygen andhydrogen in the state liquid. If the tank has been pre-tested for the detonation, then this is to check that everything works under launch countdown conditions.

After the rehearsal, NASA will announce the departure date. If all goes well, it could take off from May 7, or later in the summer as expected.There will be no one on the spaceship Orion It was placed on top of this Titanic launcher. Artemis I is a qualification mission for both European and American-built spacecraft, as well as Boeing-produced SLS. If the mission is successful, the astronauts of Artemis II will take over.

Launch Pad 39B at the Kennedy Space Center has experienced Apollo 10This American space shuttleroll out space station skylabeven the mission of peace Apollo Soyuz. It has been refurbished and reinforced to support the weight of 2,125 African elephants! It’s strong enough to hold the 2,628-ton SLS lunar rocket. The latter will only work for one hour and fifty-three minutes in the mission. The rest of the mission involves the Orion spacecraft and will last nearly 25 days.

At T-0, the release will start with the update fire Four RS-25 motors and two huge thruster fuel booster hard Courtesy of Northrop Grumman. They will be ejected after two minutes, completely running out of fuel. The RS-25 engine will continue to roar for six minutes and fourteen seconds.At this point, the main stages of SLS, which can be identified by colour Red, will do its job, we’re already at an altitude of over 150 kilometers, so in space.

Two minutes after the main stage was released, Orion spacecraft Its solar panels will be deployed. If the rocket catches fire on the launch pad or while crossing the strait, it will have gotten rid of the protective panels as well as the rescue tower, an important device for ejecting the ship and its passengers.atmosphere.

It was not until much later, 54 minutes after the start of the launch, that the thrusters of the second stage ICPS were powered by co-founded alliance (ULA). ICPS was used for the first time to gain altitude, the second time after half an hour to inject the Orion into a transfer track towards the moon. Once its task is complete, ICPS is discarded.Then we’ll take the opportunity to pop a dozen cube satellite Who is the secondary passenger on this flight.

around the moon

This isn’t Orion’s first demonstration flight.As part of this program, it already made its maiden flight in 2014 Constellation, the predecessor of Project Artemis.This flight will allow him to once again test the manned module built by Lockheed Martin, and service module Provided by the European Space Agency (ESA). Orion will reach the same trajectory as the mission’s trajectory during the Artemis I mission Apollo 8.

It will take a little more than three days to reach the moon.To get into orbit, Orion will pass nearly 100 kilometers from the surface and will use gravity the moon to increase its speed. With the help of some corrections, the ship will enter a retrograde orbit around the moon. In fact, the spacecraft will orbit the Moon in the opposite direction to the Earth.

The Orion spacecraft will remain in lunar orbit for just over six days. NASA will take the opportunity to recover data and test the spacecraft’s various communications and navigation systems.To communicate with him, NASA will use deep space networkan antenna array for interacting with interplanetary probes.

The Orion spacecraft will conduct an experiment (Mare), the purpose of which is to measure the radiation levels that the crew on board may be exposed to.Around the Moon, we are almost no longer affected by Earth’s magnetic field it is deflected by Sun. On board, two mannequins will be covered sensor One of them will be wearing an experimental vest, which is supposed to block some radiation.

Return to Earth and continue the program

After leaving lunar orbit and returning to Earth, Orion will once again accelerate through an altitude of nearly 100 kilometers, using not only the lunar gravity but also the host of the service module. It then places itself on a transfer orbit in the direction of our planet. The trip should last a little over three days.

The Orion spacecraft will return to Earth after a three-week journey of more than 1.3 million kilometers. The habitable module will be separated from the service module before entering Earth’s atmosphere. The latter is unprotected, it will burn in the atmosphere during a fall, and the Habitable Module will pass through it, protected by its heat will end its descent parachute. It should land in the Pacific Ocean near California. The task of Artemis I will be completed.

The rest we have to wait patiently, depending on the outcome of the first mission. Artemis II shouldn’t take place before 2023 or even 2024. This will be the program’s first mission with astronauts, but they won’t land on the moon. They’ll just go around it in “rehearsal” mode, like Apollo 10.that’s the task Artemis III This will bring astronauts back to the surface of our natural satellite, including the first moonwalk in history.
