NASA Relies on Human Vision for Artemis-2 Lunar Mission

Kathmandu. Even in the era of advanced technology, NASA is once again placing its trust in the human eye for lunar exploration. More than five decades after humans first orbited the Moon, the astronauts of Artemis-2 are preparing to replicate that achievement on Monday, observing the lunar surface with their own eyes.

Despite significant technological progress since the Apollo missions, NASA scientists still consider direct human vision indispensable. According to Artemis-2 mission lead scientist Kelsey Young, the human eye is the most capable 'camera' itself, capable of distinguishing subtle details and colors more effectively than a camera. She noted that the high number of receptors in the human eye plays a crucial role in visual analysis.

While modern cameras are superior in some aspects, she argues that the human eye's ability to distinguish colors, understand context, and analyze interactions with light remains unique. Humans can easily perceive how surface texture and color change as the angle of light shifts, which is considered scientifically invaluable.

Orion spacecraft pilot Victor Glover described the human eye as a 'magical instrument' before departure. During the space journey, they are expected to identify subtle changes on the lunar surface through direct observation.

The four-member team for this mission has spent over two years in rigorous training. Along with classroom studies, geological exercises in Iceland and Canada, and lunar flight simulations, the goal was to turn them into 'field scientists.' American astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with Canada's Jeremy Hansen, have practiced orienting themselves by memorizing 15 key lunar features.

During training, inflatable lunar globes were used to observe the effect of the sun's angle on surface color and texture. Scientists believe this has refined their observational skills and note-taking abilities. According to Kelsey Young, the team is not only excited but fully prepared.

Under the mission, the astronauts will study various lunar sites according to 10 key scientific objectives set by NASA. The flight around the Moon will last for several hours, during which they will conduct direct observations alongside using cameras.

According to NASA planetary geology lead Noah Petro, the Moon will look like a basketball held at arm's length to the astronauts. He stated that the most interesting aspect will be the identification of subtle colors on the lunar surface, which could provide important clues about its composition and history.

David Kring of the Lunar and Planetary Institute noted that while the possibility of a major new discovery is lower due to the availability of many high-resolution images since the Apollo era, the descriptions of details seen firsthand by the astronauts will be historic in their own right. According to him, this will be the first time in at least two generations that people will hear such firsthand accounts.

NASA will broadcast the Artemis-2 flight live, although there will be a temporary loss of contact when the spacecraft reaches the far side of the Moon. Kelsey Young mentioned that hearing the descriptions provided by astronauts during simulations was an exciting experience, and she expressed confidence that the actual flight will yield even more extraordinary observations.
