Who is Going to the Moon For? — Why Manned Spaceflight Still Captivates Our Hearts

Why Are People So Captivated by Dangerous Spaceflights?

Scheduled for launch after April 1, 2026, NASA's Artemis II is a manned lunar orbit mission that will carry four astronauts to fly near the moon for about ten days before returning to Earth. This is not merely a technical test; the very fact that humanity is heading near the moon again for the first time in over half a century is already a significant story. With this flight, NASA aims to put humans aboard the SLS rocket and Orion spacecraft for the first time, testing life support and deep space operational capabilities.

The core of the original article published on Phys.org is clear: spaceflight attracts audiences because there are "people" involved, and those people are putting themselves in danger. Robotic exploration is cheaper, more rational, and has a wider margin for failure. Yet, it is often the manned missions that capture the world's attention. It's not efficiency but the presence of individuals that moves people's emotions. Space development is a story of human endeavor in the face of adversity, as much as it is about technology.

This perspective becomes even clearer when looking at the current trends in space development. In March 2026, NASA effectively revised the lunar orbiting base Gateway and shifted its focus to the "lunar base" concept, enabling sustainable activities on the moon's surface. The plan is phased, with an increase in robotic landings carrying rovers, scientific instruments, power, communication, and transportation means from 2027 onward, eventually progressing to long-term human stays. In other words, the actual lunar development is designed with a division of roles between robots and humans from the start, not progressing with "humans only."

Yet, manned flights still take the forefront. Why? One reason is that the dangers of space are overwhelmingly human. NASA identifies space radiation as one of the major health risks in long-term manned exploration. In a weightless environment, without proper measures, bone density in weight-bearing bones decreases by about 1% per month, and muscles also atrophy. The moon's gravity is one-sixth of Earth's, and Mars is about one-third, but what these "partial gravities" will do to the human body in the long term is still not well understood.

In fact, very few people have experienced going to the moon. According to NASA, 24 people traveled to the moon between 1968 and 1972, and only 12 of them actually walked on the lunar surface. Even during Apollo 17, the lunar stay was limited to about three days. Humanity may seem to know the moon, but it has no experience of living there for long. Artemis II is drawing attention because it is stepping into a realm that humans have barely experienced, even before it serves as a "prelude" to future base construction and Mars exploration.

This feeling of "wanting to see because people are going" is also reflected in the reactions on public SNS and online communities. In the Reddit space community, users who know the Apollo era speak of eagerly awaiting Artemis, and other posts mention preparations to head to the site to watch the launch live. Reuters also reports on people capturing images of the SLS standing on the launch pad. For space fans, Artemis II is not news but an "event to witness."

 

On the other hand, the reactions are not all enthusiastic. Due to ongoing delays and technical issues, there are many voices expressing anxiety. AP reported a two-month delay due to issues like fuel leaks, and on Reddit, reactions like "Honestly, I'm quite anxious" and posts suggesting "We should just build a lunar base with advanced robots without humans" are prominent. Those skeptical of manned flights are critically evaluating whether the scientific and practical returns justify the risks and costs.

This counterargument indeed has persuasive power. The original article also acknowledges that robotic exploration is lower cost and can accept higher risks. Moreover, NASA itself is accelerating numerous robotic landings and technology demonstrations as a precursor to lunar surface activities. In other words, "humans or robots" is not a binary choice. Machines are sent to dangerous places first, and humans are sent when there are roles that only they can fulfill. Future space development will question where to draw that line.

However, there are reasons why manned flights cannot be completely replaced by robots. One is that the human body itself is also a subject of exploration. Adaptation to deep space radiation, long-term stays, and partial gravity ultimately connects to the question of whether humans can live in space. On Reddit, there are counterarguments like "The effects of long-term spaceflight on the human body cannot be studied by robots." Manned spaceflight is not just about exploring space but also about the science of studying "humans who have gone into space."

Another reason is what nations and societies seek from space development. As seen from explanations by Reuters and NASA, the Artemis program is backed by competition with China, expectations for lunar resources and industrialization, and even the concept of using the moon as a stepping stone to Mars. However, to have the public understand these strategic goals, abstract policy documents alone are not enough. When there are four faces to see, expressions before departure to convey, and reasons to await their return, only then can the massive budget of a space program be shared with society through such "human stories."

Therefore, what Artemis II reflects is not just the advancement of space technology. It also reveals our true feelings about what we project into space. If safety is the only concern, robots will suffice. If only rationality is sought, that answer is quite correct. But people do not become passionate about purely rational things. When there is someone who understands the danger and still chooses to move forward, applause, prayers, and discussions arise. The reason spaceflight still holds a strong allure is that every time humans go into space, it is not technology but humanity itself that is tested.

Artemis II is both a test flight for going to the moon and a public experiment of the age-old question, "Should humans still go?" The expectations, anxieties, doubts, and aspirations overflowing on SNS are society's wavering answers to that question. The conclusion is not yet reached. But at least it is certain that while the next era of space development may proceed with robots alone, it will not advance without interest in humans. The main reason Artemis II is drawing attention is not the moon but because the world's emotions are tied to the four people inside the spacecraft.
