SharePlusAs humanity looks toward crewed missions to Mars, researchers are highlighting significant physiological risks. Deep space travelers face severe health hazards from cosmic radiation and microgravity. While scientists understand that these elements negatively affect human biology, the full severity and long-term consequences remain largely unknown.
Applying medication to the eyes is notoriously difficult in microgravity environments due to fluid dispersion and the absence of downward force. To solve this challenge, a collaborative research team from KAIST and Seoul National University Bundang Hospital has developed an innovative wearable patch. The newly invented device delivers precise doses of liquid medication directly to the ocular surface without depending on gravity. Published in Sensors and Actuators B: Chemical, this breakthrough promises to improve astronaut healthcare during long-duration space missions.
Four astronauts have successfully returned to Earth from the International Space Station on Thursday. They had originally hurried to the orbital outpost eight months ago to replace an ailing colleague and his crew.
