HOUSTON, TX, October 12, 2018 / 24-7 PressRelease / – NASA is stepping up the pace to learn about five dangers of spaceflight and how they can collectively affect the human body and mind in the future. 39; space. In a recent bid solicitation, the agency seeks to address these risks to enable safe, reliable and productive exploration of the human space.
NASA's Human Research Program (HRP) is responsible for discovering the best methods and technologies for supporting safe and productive human space travel, bringing together five-part activities to address the dangers of manned spaceflight . With this new research opportunity, NASA was seeking a fully integrated approach to explore the relationships between radiation, isolation and confinement, modified gravity fields and the potential damage they cause to the central nervous system, to health. behavioral and sensorimotor system of an astronaut – known collectively. like CBS.
"CBS illustrates the complexity of the deep space environment and is designed to understand the simultaneous adverse effects of the three hazards or stressors on humans," said Jennifer Fogarty, Chief Scientist of the Human Research Program. Johnson Space Center at NASA in Houston. "For example, it has been shown that spatial radiation, microgravity and isolation had an effect on the central nervous system, your brain, when they were studied one after the other." We are concerned that the areas of the brain affected by each danger will worsen when stressors are felt at the same time, which could change the way you think, move your body, and react emotionally to events and situations. teammates during the mission, which may not be successful, many spatial factors combine to make it an extremely complex environment. "
As part of this solicitation, HRP has adopted a comprehensive and fully integrated approach to managing the central nervous system, behavioral health and sensorimotor system of an astronaut. Appendix A of the 2018 Exploration and Human Search Opportunities asked research teams in specialized areas to apply their skills to the problem; The unique expertise of each discipline should accelerate scientific discoveries.
"An integrated approach takes advantage of the combined research on brain power and crosses," said Fogarty. "It's a critical period. Our concern for the health and safety of astronauts demands that we find answers to the complex combination of risks to which astronauts will be exposed during deep-space exploration missions on the Moon and Mars. This integrated approach of teaming together to understand the problems of human exploration in the deep space will accelerate the process and give us a much more realistic picture of the risks. "
The paper addressed issues such as:
• What happens to the central nervous system of the body in space? Are significant changes occurring over time? How should science define the term "significant"?
• What is the probability that spatial radiation affects the nervous system? How are you going to look like? Are there any characteristics (called "biomarkers") that scientists can identify to indicate that space radiation has effects on the body?
• What are the most effective medical or dietary countermeasures (prevention methods and protective measures) to reduce the risk of harm? How would these countermeasures work in space?
• How to integrate new data from molecular, cellular, tissue and animal models into our growing body of knowledge about the human body in space? Is there research on mobility, cognitive function, or behavioral change that may be useful in assessing the risks to the central nervous system of astronauts?
• Are there significant risks to the central nervous system of space radiation when it is associated with other known hazards related to spaceflight? For example, when the risk of space radiation is associated with a risk of isolation and containment and / or modified severity, do they act together and have an impact greater than each alone?
• What is the effect of these three space-related hazards on the body's stress, sleep, respiratory function, immune system, and more?
NASA expects to have reviewed the proposals and made selections in the spring of 2019.
NASA's human research program enables space exploration by reducing the health and performance risks of astronauts through ground search facilities, the International Space Station and analog environments. This leads to the development and delivery of a biomedical exploration program focused on: information on standards of human health, performance and habitability; the development of prevention and risk reduction solutions; and advanced technologies of habitability and medical support. HRP supports innovative human scientific research by funding more than 300 research grants to renowned NASA universities, hospitals and centers, and more than 200 researchers from more than 30 states.
