NASA research could provide vital information needed to help protect astronauts during future deep-space missions and advance the prevention and treatment of disease for people on Earth.
Impacts & Benefits
-
Precision Health
NASA studies the physiological, cellular, and genetic alterations that can occur during space travel. This fundamental research can help ensure crew health and safety on their missions, as well as contribute to significant advancements in medicine for all.
Human exploration exposes astronauts and their microbiomes to spaceflight stressors. NASA’s four Precision Health focus areas will provide a mechanistic understanding of the physiological, cellular, and genetic alterations that occur during space travel. Research will expand knowledge of the short- and long-term risks of prolonged deep-space exploration, as well as the onset and progression of disease and dysfunction that could affect astronauts beyond low Earth orbit. -

Organ-On-a-Chip (Organ Chips)
Organ-chips are tiny devices that act like small versions of human organs. Made with human cells, the chips mimic how tissues, such as the brain, heart, liver, or dozens of other organs, work. NASA research, including AVATAR, will focus on validating and leveraging these models to assess the impacts of deep-space stressors on human health. Insights could advance personalized medicine in space and on Earth.
Aging and Disease
Research to-date has revealed aging-like phenotypic changes that suggest spaceflight accelerates the onset and progression of age-related disease. NASA research aims to clarify this linkage by using relevant model systems and computational modeling and analyses. Work will focus on identifying the underlying mechanisms of spaceflight aging and disease and understanding if severity is altered by the duration or destination of the mission.
Synthetic Biology
Microbes can be used as tools for protecting human health. NASA will investigate ways to engineer molecules that are beneficial to astronaut health, such as vitamins or pharmaceuticals essential for long-duration missions. This could include developing beneficial bacteria to counteract disease or expanding capabilities such as biosensors for measuring low oxygen. Synthetic biology research could yield advancements benefitting agriculture, medicine, and manufacturing.
Acclimation and Adaptation
Organisms, including humans and microbes, may acclimate and adapt to living in a spaceflight environment. Acclimation is the short-term physiological responses organisms undergo, while adaptation involves permanent genetic changes resulting from exposure to selective environmental pressures. NASA research will focus on understanding the mechanisms of acclimation and adaptation and determining whether changes are beneficial or associated with dysfunction and disease.

BPS Scientific Goals Overview
Revolutionary Research in Extraordinary Places.
NASA research contributes to breakthroughs that advance national priorities and maintain U.S. leadership in science and technology.
Studying the fundamental effects of space stressors (such as radiation and microgravity) on biological and physical phenomena promotes mission success and benefits life on Earth.

Quantum Leaps
Unraveling mysteries of the universe
While modern physics has led to numerous scientific breakthroughs, many aspects of quantum phenomena remain unexplained. NASA’s research conducted in space offers unique opportunities to advance quantum science in ways that Earth-based studies cannot. Technologies like smartphones, computers, GPS, and medical imaging all stem from quantum research. Continued exploration in this field could contribute to innovations beyond our most imaginative theories.

Foundations
Revealing the novel behaviors of fluids, fire, and materials in space
Physical phenomena behave differently in space: how flames burn, fluids flow, and materials react to extreme conditions. Research in these areas can lead to scientific breakthroughs and new technologies that enable safe, sustained missions to the Moon, Mars, and beyond. It can also contribute to everyday life, including improvements in fire safety, manufacturing, commercial products, and more.

Space Crops
