Between March 2015 and March 2016, a man spent a total of 357 hours being poked and prodded: sacrificing blood and urine, sweating through sprints and letting others read his journals oh; and living on the International Space Station. The man was Scott Kelly, and with his Russian counterpart, Mikhail Kornienko; he spent a total of 340…

Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The invention that measures astronauts’ levels of radiation exposure will improve the safety of humans and electronics during space missions. In other words, UOW…
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to fundamental importance to an understanding of the physical universe. Research Institute for Space Health The Translational Research Institute…
More people today are poised to explore space than ever before; those who will experience the effects of microgravity on the human body. Recognizing the need for more data related to those effects, Medical University of South Carolina (MUSC) neuroradiologist Donna Roberts, MD, and co-author Lonnie G. Petersen, Ph.D., "The Study of Hydrocephalus Associated With Long-term Spaceflight (HALS) Provides New Insights into Cerebrospinal Fluid Flow.
NASA hopes to send humans to Mars by 2030 on a round-trip mission that could take up to three years far longer than any human has ever traveled in space. Such long-term spaceflights could adversely affect certain cells in the immune systems of astronauts, according to a new study led by University of Arizona researchers.
As space continues to play an increasingly critical role in our nation’s defense, the need for the space medicine specialty grows. Medical Airmen within U.S. Air Force Space Command are making sure space operators are ready for future readiness requirements.
Humanitarian relief organization Airlink has partnered with Ethiopian Airlines, Boeing, and the Afya Foundation to transport specialty microscopes to treat hundreds of patients awaiting ear surgery. The unique partnership between nonprofits and the private sector is bringing relief to hundreds of children awaiting surgeries for chronic ear diseases in Adama, Ethiopia.
As the Air Force’s interest in the future of space warfare mounts, Wright-Patterson Air Force Base could be at the helm of the Defense Department’s research efforts. The Air Force last week released a report created by the National Air and Space Intelligence Center (NASIC) detailing growing challenges in the space domain.
The human spaceflight environment is notable for the unique factor of microgravity, which exerts numerous physiologic effects on macroscopic organisms, but how this environment may affect single-celled microbes is less clear.
When flight vehicles (e.g., aerospace vehicles, Low Earth Orbit (LEO) satellites, near-space aircrafts, Unmanned Aerial Vehicles (UAVs) and drones) fly at high speed, their surfaces suffer the micro-pressure from high-altitude thin air. The long-term effect of this pressure causes the surface components of flight vehicle to deform or fall off, which can lead to a serious accident.
The objectives of this study were to quantify decrements in controlling tilt on astronauts immediately after short-duration spaceflight and to evaluate vibrotactile feedback of tilt as a potential countermeasure. Eleven subjects were rotated on a variable radius centrifuge (216°/s <20 cm radius) in a darkened room to elicit tilt disturbance in roll (≤± 15°).
Researchers have had a rare opportunity to see how conditions on the International Space Station translated to changes in gene expression by comparing identical twin astronauts one of the twins spent close to a year in space, while the other remained on Earth.
