Did you know there’s a side of the moon we never see from Earth? It’s called the far side, and it does get sunlight, just like the side we see. But that’s not the most interesting part. What’s really intriguing is the danger posed by moon dust.
When astronauts first landed on the moon, they kicked up a lot of dust. This dust turned out to be a big problem. Some astronauts even had allergic reactions to it! For example, in 1972, an astronaut named Harrison Schmitt experienced sneezing, red eyes, and an itchy throat after being exposed to moon dust. Imagine being allergic to something from the moon! But the issue is more serious than just sneezing.
As space agencies plan more missions to the moon, they’re worried about the dangers of lunar dust. This dust is sharp and rough, like tiny pieces of glass. Since there’s no wind on the moon, these particles stay sharp and can damage spacesuits or clog equipment. Breathing in this dust can also be harmful to health.
Scientists at Stony Brook University wanted to understand the risks of moon dust. They studied two iron-based compounds found on the moon by soaking them in a solution similar to human lung fluid. After about 15 minutes, they found that the dust produced harmful compounds called hydroxyl radicals. These can damage cells in the lungs. Because the dust is so sharp, it can be especially harmful to lung tissue.
The research shows that moon dust could have serious long-term health effects. It likely contains silicon dioxide, which is known to be toxic and can cause lung diseases. This is important because NASA’s Artemis program plans to send humans back to the moon soon.
NASA is working on new spacesuit designs to help with the dust problem. These suits will have better mobility and insulation. They won’t have zippers or cables, which can trap dust, and will include special sealants to keep dust out. While these changes are promising, more work is needed to manage the dust, like using vacuums to clean suits before taking them off.
More research is needed to understand the compounds on the moon and their effects on human health. A workshop on this issue is coming up, led by a professor from William & Mary. It’s exciting to think about the new ideas that will come from this research as we prepare to return to the moon.

It turns out there’s a lesser-known aspect of the moon that might surprise you. The side of the moon that we never see from Earth is more accurately called the far side, as it does receive sunlight. However, that’s not the main point. What I want to highlight is that the moon poses certain dangers, particularly its dust.
When the first astronauts landed on the moon, they stirred up a significant amount of dust, which became a persistent issue. Some astronauts have even had reactions to it. For instance, in 1972, Apollo 17 astronaut Harrison ‘Jack’ Schmitt experienced symptoms like sneezing, red eyes, and an itchy throat after exposure to moon dust. While that might sound uncomfortable, it’s fascinating to think about being allergic to something from the moon. However, the implications can be more serious than just temporary discomfort.
As space agencies plan more crewed missions to the moon, researchers are investigating the hazards these missions may encounter, and lunar dust is a significant concern. The dust is sharp and abrasive, similar to tiny shards of glass. Since there’s no wind on the moon, the particles remain sharp and can damage spacesuits or clog equipment, which is problematic. Inhaling this dust can also pose serious health risks.
To understand the risks of exposure, a team at Stony Brook University studied two iron-based compounds found on the moon by soaking them in a solution that mimics human lung fluid. After about 15 minutes, they observed the production of hydroxyl radicals, reactive oxygen compounds that can harm biological tissue at the cellular level. These particles can remain in the lungs for an extended period, potentially causing more damage than what was measured in the initial study. Given their sharpness, they can be particularly harmful to lung tissue.
The research indicates that moon dust could have serious long-term health implications. Additionally, silicon dioxide, which is likely a significant component of lunar dust, is known to be toxic and can cause lung diseases. This research is timely, as NASA announced the Artemis program, aiming to send humans back to the moon by 2024. There is an urgent need to address the challenges posed by moon dust.
NASA is already innovating with redesigned spacesuits that enhance mobility and insulation while addressing the dust issue by eliminating zippers and cables, reducing creases, and incorporating special sealants. While these improvements are promising, further consideration is needed regarding dust management, including potential vacuum-cleaning processes before suit removal.
More research is necessary to understand the compounds present on the moon and their effects on human health as astronauts explore. A workshop focused on the dust issue is scheduled soon, led by a professor from my alma mater, William & Mary, which I find very exciting. I look forward to the innovations that will emerge to tackle this challenge and others as we prepare for our return to the moon.
