Space Policy Events For March-2019

House and Senate hearings on the FY2020 budget request begin in earnest this week; with appropriations or authorization hearings on DOD, NASA, NOAA, and the Department of Transportation (DOT).  DOT appropriations hearings usually focus on high-level issues, so it is not likely that the FAA’s commercial space transportation activities; will discussed to any great degree,…

Astronauts Embark On Hours-Long Spacewalk

An astronaut or cosmonaut is a person train by a human spaceflight program to command, pilot, or serve as a crew member of a spacecraft. Although generally reserved for professional space travelers; the terms are sometimes to anyone who travels into space, including scientists, politicians, journalists, and tourists. Until 2002, astronauts were sponsored and trained exclusively by governments;…

Herpes Viruses Reactivate During Spaceflight

Herpes viruses reactivate in more than half of crew aboard Space Shuttle and International Space Station missions; according to NASA research published in Frontiers in Microbiology. While only a small proportion develop symptoms; virus reactivation rates increase with spaceflight duration and could present a significant health risk on missions to Mars and beyond. NASA’s rapid…

Long-Duration Spaceflight

Long-Duration Spaceflight Adversely Affects Post-Landing Operator

For future exploration-class missions to asteroids or other planetary bodies crewmembers; will required to perform operational tasks following extended periods of microgravity exposure. It is well documenting that astronauts returning from long-duration missions to the International Space Station (ISS); exhibit adverse sensorimotor, cardiovascular and neuromuscular effects upon return to Earth due to in-flight adaptation to…

Herpes Virus Reactivation In Astronauts During Spaceflight

Latent herpesvirus reactivation has demonstrated in astronauts during shuttle and International Space Station (≥180 days) flights. Following reactivation, viruses are shed in the body fluids of astronauts. Typically, shedding of viral DNA is asymptomatic in astronauts regardless of mission duration; however, in some cases, live/infectious virus was recovered by tissue culture that was associated with…

Doctors Need To Bone Up On Spaceflight

Civilian doctors need to start boning up on the medical implications of time spent in microgravity in readiness; for the advent of commercial spaceflight; researchers warn. Until now, they say, all astronauts have rigorously healthy and fit people who have to match the high standards imposed by NASA; other state-owned space agencies around the world.…

Space Medicine: War on Flu and Pneumonia, Sleep

Space medicine is the practice of medicine on astronauts in outer space whereas astronautical hygiene is the application; of science and technology to the prevention or control of exposure to the hazards that may cause astronaut ill health. Both these sciences work together to ensure that astronauts work in a safe environment. The main objective…

Space Medicine In The Era Of Civilian Spaceflight

Since the first human spaceflight by Yuri Alekseyevich Gagarin in 1961, more than 560 persons have flown in space. The vast majority of highly trained and rigorously selected astronauts in excellent physical condition and health. Currently, astronauts and other participants in spaceflights to the International Space Station must adhere to medical certification; standards set by…

Agreement On Cooperation In Science, Engineering And medicine

Space research is a scientific study out in outer space, and by studying outer space. From the use of space technology to the observable universe, space research is a wide research field. Earth science, materials science, biology, medicine, and physics all apply to the space research environment. The term includes scientific payloads at any altitude…

Considerations For Fixed-Wing Air Medical Transports

The need to move ill or injured patients from one location to another by air is not a new concept. Injured soldiers among the first patients in history to transport by air to a medical facility; beginning with the use of hot air balloons in 1784. Since fixed-wing aircraft was developed in 1903; the use…

Health Effects Of Particulate Matter From Aircraft Engines

Aircraft emissions contribute to local and global air pollution. Health effects of particulate matter (PM); from aircraft engines are largely unknown since controlled cell exposures at relevant conditions are challenging. They examined the toxicity of non-volatile PM (nvPM) emissions from a CFM56-7B26 turbofan; the world’s most used aircraft turbine using an unprecedented exposure setup. So…

Magnificent Women And Their Flying Machines

One of the best places to hear stories of women breaking traditional barriers is in the Indian Air Force (IAF); more generally, women who work in and with the sky. For me, it’s the most exciting subversion of a range of elite jobs fighter pilot; aerospace engineer, navigator, missile scientist, aviation medicine specialist that have…
