For five years, researchers with the European Space Agency have analyzed exhaled Nitric Oxide in astronauts’ breath to detect dust and other toxins. Future astronauts on the Moon or Mars could inhale dust that has collected in their habitats or on their spacesuits potentially inflaming their airways. Monitoring a crewmember’s airways could improve the mission environment and optimize crew health for a successful long-term mission. The research has also contributed to asthma diagnosis and treatment back on Earth. This week the crew completed the final session on the final subject for the investigation. Astronauts on the ISS have been breathing for the sake of science as part of ESA-sponsored research. Under the scientific lead of Lars Karlsson from the Karolinska Institute in Sweden, this research has been ongoing for more than 10 years, most recently within the Airway Monitoring experiments. These experiments analyze the amount of nitric oxide exhaled by astronauts under different conditions in the weightless environment of space (e.g., normal pressure, reduced pressure in an airlock, pre-/post-spacewalk etc.) The astronauts breathe into a specially developed instrument that measures nitric oxide levels. The purpose of taking reduced measurements in an airlock––normally used to exit a spacecraft for spacewalks, and is set at a 30% reduced pressure–– is to simulate conditions in future habitats on Mars, and is equivalent to being at 3000 m (9843 ft) altitude on Earth. The device that measures the nitric oxide is lightweight, easy to use and accurate. The same instrument is currently used in clinics and hospitals, helping asthmatics and offering a quick and cheap way to diagnose lung problems. It was developed in close collaboration between the medical technology industry and the researchers at Karolinska Institute. In a similar collaboration with the pharmaceutical industry, the same researchers developed a nitric oxidedonating drug (Supernitro) with a uniquely selective effect in lung circulation. The drug widens the blood vessels and counteracts life-threating increases of the local blood pressure. On the Moon and on Mars, astronaut’s lungs may become easily irritated or inflamed by dust particles. The reduced gravity on those celestial bodies makes floating dust a real threat for humans. Understanding the effects of weightlessness and reduced pressure on airway health will help space explorers monitor, diagnose and treat lung inflammation during spaceflight. This information is key to ensuring the health and safety of astronauts on longer missions beyond Earth’s orbit. ... https://www.youtube.com/watch?v=55vuhzYXFyo
