The return of humans to the Moon.




In February 2026 it will move on to one of the most important astronomical events, Artemis 2, possibly around February 5 or 6, which is when the launch of the Artemis 2 mission is more or less scheduled. If things do not go well, which could happen, NASA manages a period of opportunities or windows that extend during February, March and April 2026, depending on the weather conditions, the orbital alignment and how if a failure has occurred, if They have managed to repair it, obviously.


The launch will be with the SLS rocket, this wonderful and very expensive rocket, and the ship that will take the astronauts to the orbit of the Moon will be the Orion capsule, which both are already in the vehicle assembly building in Florida, where they also carried out the last integration tests and drills with the crew.


This is going to be the first manned mission of the Artemis program, carrying out a lunar flyby without landing on the moon, that will be the third and what they will do is test all the life support systems before returning to the lunar surface, which will be the Artemis 3 mission. This mission will last approximately 10 days, it would be the first manned mission that leaves Earth's orbit since the Apollo 17 mission, which was on December 7, 1972, since then, humans have not gone much further. about 500 km from the Earth's surface, not much further.

If everything goes well, furthermore, because it is not certain that they will achieve it, the crew of the Artemis 2 could also beat the current record of 400,171 km. distance from Earth reached by humans, which was achieved by the crew of the Apollo XI mission. Although that was a tragic disaster because due to the accident they had to take a different orbit around the Moon that allowed them to reach that distance.


The Artemis 3 mission will mark the physical return of human beings to the moon, to the lunar surface, it has undergone several calendar adjustments and as of today, December 29, and this is not a joke, the official launch date is scheduled for mid or late 2027, which I do not believe because, among other things, there are internal documents that already mention 2028º and keep in mind that the SpaceX lunar lander must be ready, which is still a long way off.


We have to see before 2027, even before it should be at the end of this year at most, although it is not scheduled, to see the landing rocket of SpaceX, which would be a SpaceX rocket adapted to land on the moon, must be seen because they have to do the tests to see if it lands correctly, and then we will have to see what happens next with the Artemis 3 (Artemis 4).




Return humans to the moon, the Americans would return, because China is also in it, their goal is 2030, they are about one or two years behind the United States right now, but it all depends on how things go, one of the things we will see will be, Chinese and Americans on the Moon. Who arrives first?


The Chinese, I don't know how the budget thing is, but the American side is very very complicated, that rocket, the SLS, costs 4.1 billion dollars each launch, it is disposable, that is, every time an SLS takes off, like the mission we are going to see, the Artemis 2, the entire rocket is destroyed, it falls into the ocean, part of it integrates into the atmosphere and another part falls into the ocean, but nothing is reused, so we have to build a new one from scratch for each mission.


That is as if you destroyed a Virginia-class nuclear submarine every time something is launched to the moon. Initially the mission is to put up the flag and the photo, but then it is planned to build a space station orbiting the moon and a lunar base and that means a lot of material, a lot of equipment and periodically sending a crew, that is, destroying a Virginia-class nuclear submarine every time something is launched to the moon, they are not going to do the math.
