Why Send Humans to the Moon When Robots Can Explore Space?

With today’s advanced probes and robotic tools, what is the purpose of sending human astronauts into space?

What Humans Add to Lunar Exploration

If the goal is simply to take a photo, a robot can do that. Robotic spacecraft routinely capture images, and the International Space Station can also be asked to photograph specific locations. But that is not the purpose of Artemis II—or of the planned Artemis III, IV, V and VI missions.

The Artemis program is designed to maximize human capabilities. Humans are especially good at taking in a wide landscape, quickly focusing on important details, interpreting what they see and deciding what to do next.

Why Human Astronauts Matter on the Moon

Scientists and engineers still do not know everything about the Moon. Learning more requires going above ground, examining the environment directly and determining where to explore next. Artemis training is therefore designed to prepare not only the astronauts, but also flight directors, science teams and engineers. Enabling humans to do what they do best requires all of these groups to work together.

How Astronauts Interpret What They See

Human astronauts can also provide scientific insight in real time. Teams may ask questions such as: What do you think is happening in this scene? Does it resemble a storm, an algae bloom or a fire? What do you see? How is the scene changing? What might be causing that change, and what could happen next? If you could take action, what would you do?

This approach helps scientists understand what astronauts are seeing instead of merely collecting images. Humans can observe, understand and reason about their surroundings. That ability is what the Artemis missions ask astronauts to bring to lunar exploration.
