Underwater environments simulate the conditions of space exploration and allow NASA to test equipment, perform research, and prepare for future missions in extreme settings such as the moon or Mars. Being underwater replicates the isolation, confined spaces, and limited resources astronauts experience in space.
I am a 55-year-old avid diver who made about 300 dives in 2023, most of which were coldwater shore-entry dives near San Diego, California, to below 100 feet (30 meters). […]

Researchers at the University of Colorado Boulder’s Shields Lab — led by Wyatt Shields, PhD, an assistant professor of
chemical and biological engineering — are investigating how engineered microparticles, specifically designed for use in biomedicine, can be used in areas such as biosensing, where they bind to certain molecules or cells to enable drug delivery and the detection of biological conditions.
Diving has inherent risks. The human body was not designed to be underwater, and drowning, decompression illness, barotrauma, hazardous marine life injuries, and preexisting health issues all require an emergency response. Diving in remote areas introduces additional risks, especially access to medical care.
