The journey to return humans to the lunar vicinity is no longer a matter of distant planning. As NASA prepares for the la misión Artemis II sobrevuela la Luna en vivo: última hora, imágenes y noticias, the world is bracing for a historic flyby that serves as the critical bridge between robotic exploration and the eventual landing of astronauts on the lunar surface. This mission is not merely a flight test; it is the first time in over half a century that humans will venture beyond low-Earth orbit.
Artemis II represents a pivotal step in the Artemis program, designed to prove that the Orion spacecraft and its life-support systems can sustain a crew during a deep-space trajectory. Unlike the previous Artemis I mission, which sent an uncrewed capsule around the Moon, Artemis II will carry a crew of four astronauts who will loop around the lunar far side before returning to Earth.
The stakes for this mission extend beyond technical validation. By orbiting the Moon, NASA aims to refine the operational protocols required for the subsequent Artemis III mission, which intends to land the first woman and first person of color on the lunar south pole. The precision required for this trajectory is immense, relying on a complex choreography of gravity assists and precise engine burns to ensure the crew’s safe return.
Although the modern mission focuses on the future, the scientific foundation for Artemis is built upon the legacy of the Apollo era. The understanding of what the Moon is—and where it came from—was fundamentally rewritten by the samples brought back decades ago, a legacy that continues to inform the goals of the current lunar exploration architecture.
The Geological Mystery: How the Moon Was Born
For decades, the origin of the Moon was one of the most contested debates in planetary science. Before the Apollo landings, researchers were split between several competing theories: some believed the Moon was a “captured” asteroid from elsewhere in the solar system, others suggested it formed alongside Earth as a “sister” planet, and some theorized it was flung from Earth during a period of rapid rotation.
However, the physical evidence collected during the Apollo missions provided a definitive clue. According to Carolyn Crow, an assistant professor in the Department of Geological Sciences at the University of Colorado Boulder, the Apollo samples pointed toward a far more violent and cohesive origin story.
The key was the discovery of anorthosite, a specific type of igneous rock. While anorthosite is rare on Earth in its isolated form, it was prevalent on the Moon’s near side. This suggests the Moon once experienced conditions that allowed for the formation of a massive “magma ocean.”
Crow explains that for anorthosite to form in such abundance, a vast pool of magma must crystallize slowly, allowing the mineral to float to the top as the magma cools. This evidence, combined with the analysis of chemical isotopes, revealed that the Moon and Earth are fundamentally made of the same material.
Dr. Lori Glaze, acting associate administrator of NASA’s Exploration Systems Development Directorate, emphasizes that the chemical signatures—essentially the “fingerprints” of planetary bodies—found in Apollo rocks match those of Earth’s mantle. This suggests that the two bodies formed at the same time and from the same source.
The Giant Impact Theory and the Magma Ocean
The convergence of this evidence led to the current prevailing scientific theory: the Giant Impact Hypothesis. This theory posits that an object roughly the size of Mars collided with the early Earth. The collision was so energetic that it expelled a massive amount of molten material into orbit, which eventually coalesced to form the Moon.
The presence of anorthosite proves that the entire lunar orb was once a molten ocean. This geological history is exactly what Artemis II and subsequent missions seek to explore further. By returning to the Moon, NASA is not just repeating a feat of engineering, but pursuing a deeper understanding of the solar system’s evolution.
Comparing the Eras of Lunar Exploration
| Feature | Apollo Program (1961-1972) | Artemis Program (Current) |
|---|---|---|
| Primary Goal | First human landing / Cold War prestige | Sustainable presence / Deep space prep |
| Crew Diversity | All male, U.S. Astronauts | Inclusive; first woman and person of color |
| Technology | Analog systems / Saturn V rocket | Digital systems / Space Launch System (SLS) |
| Target Site | Lunar Equator / Maria | Lunar South Pole (Water-ice deposits) |
What to Expect During the Artemis II Flyby
As the mission approaches, the focus shifts to the operational “last mile.” The crew will undergo rigorous training in the Orion capsule’s interfaces, focusing on manual maneuvers and emergency protocols. The trajectory is designed as a Free Return Trajectory, meaning that if the main engine fails, the Moon’s gravity will naturally swing the spacecraft back toward Earth.
The mission’s timeline involves several critical checkpoints:
- Launch: The Space Launch System (SLS) rocket will propel the Orion spacecraft out of Earth’s atmosphere.
- Trans-Lunar Injection: A critical burn that puts the crew on a direct path toward the Moon.
- Lunar Flyby: The spacecraft will swing around the far side of the Moon, providing a unique perspective of the lunar surface.
- Re-entry: A high-velocity atmospheric entry into the Pacific Ocean, testing the heat shield’s integrity at speeds significantly higher than those experienced in low-Earth orbit.

The Path to the South Pole
The ultimate objective of the Artemis program is the establishment of the Artemis Base Camp. This permanent outpost is intended to serve as a laboratory for studying the lunar south pole, where scientists believe there are significant deposits of water ice in permanently shadowed regions. This ice is critical; it can be harvested for drinking water, breathable oxygen, and hydrogen fuel for further journeys into the solar system.
By mastering the flyby in Artemis II, NASA establishes the safety margins necessary for the landing in Artemis III. The transition from “visiting” to “staying” marks a shift in human spaceflight, moving from short-term exploration to the creation of a sustainable interplanetary economy.
The next confirmed milestone for the program is the final integration and testing phase of the Artemis II Orion spacecraft, with NASA providing regular updates on crew readiness and system certifications.
