A team of researchers, led by George Cybenko and Sue McGrath, are developing a mobile agent-based system to monitor bone loss in astronauts during extended space missions. The system will analyze data on urinary calcium, diet, exercise, atmospheric conditions, and medical history to provide timely feedback and prevent bone loss.
The Deep Gulf of Mexico Benthos project aims to study the structure and functions of deepsea life forms, with a focus on the ecological impact of offshore oil production. The research team will collect data on ocean floor ecology, including biodiversity, species abundance, and environmental contamination.
Conservation biologists leverage NASA's technology for biodiversity conservation projects. Satellite and radar images are used to identify high-biodiversity areas, track changes in ecosystems, and understand the impact of human activities on wildlife populations. These studies have implications for reserve creation and corridor managem...
A virtual-reality training tool is being developed to help astronauts learn techniques for navigating complex spacecraft and maintaining orientation in microgravity environments. The device tests users' ability to maintain spatial awareness and navigate through various modules.
Researchers found American astronauts and mission control personnel reported lower emotional health scores compared to their Russian counterparts. The study suggests steps NASA can take to boost morale, such as rotating leadership roles among three-person crews.
Loren Acton, a former astronaut and solar physicist, has won the prestigious George Ellery Hale Prize for his outstanding contributions to solar astronomy. Acton's research focuses on understanding the Sun's behavior, shapes, colors, and motions.
The NASA Marshall Open House offers a daylong space adventure with interactive exhibits, including a Space Shuttle Pavilion, magnetic levitation track and International Space Station mockup. Meet astronauts, robots and celebrities, and participate in activities like the Astronaut Moon Bounce.
A new analysis by Futron estimates the risks faced by NASA's space station crew, including serious illness, deaths, and accidents inside the station. The consultancy predicts a 93% probability that a micrometeorite impact will cause disaster if it occurs.
Researchers aim to develop an exercise regimen that can prevent fainting in healthy individuals. Dr. William H. Cooke's study found that a malfunction in arterial pressure sensors and inadequate neural response to blood volume decreases may cause fainting. The investigation explores the effects of different exercise training programs o...
A study by NASA's Johnson Space Center found that spaceflight increases the levels of Epstein-Barr virus (EBV) in astronauts' saliva samples. EBV can cause glandular fever and has been associated with Burkitt's lymphoma, a type of cancer common in Africa.
NASA gave astronauts melatonin to improve sleep, but found no benefit; instead, electrodes seemed to help them relax and sleep better. Astronauts' duties likely cause insomnia, and monitoring equipment helps them see sleep as part of their mission.
Researchers have developed a unique antenna design called the Orlan antenna to provide communications and vital signs for astronauts on the International Space Station. The antenna's special loop design couples sufficient energy to transmit radio-frequency signals while minimizing reflections.
Orthostatic intolerance affects at least 70% of returning astronauts due to the body's adaptation to weightlessness. Astronauts often struggle with standing and may have puffy faces and thin legs during and after space travel. Researchers are studying this condition to improve astronaut health for future long-duration missions.
