Expecting the Risk of Space – Unpredictable Solar Particle Events and Galactic Cosmic Rays


Unpredictable (SPEs) Solar Particle Events and (GCR) Galactic Cosmic Rays pose a considerable threat to astronauts during their space expedition. Every source of radiation has an exceptional effect on the wellbeing of human tissue, shielding style, and mitigation techniques during spaceflight operation. Scientists are not certain of how instantaneous and extended exposure to the radiations will affect long or short term human wellbeing.

Along with the distinguished treats of space- crushing pressures, freezing temperatures, isolation- astronauts also encounter threats from radiation that can injure body organs or cause serious illness.

Though not thought to be a forthcoming risk of current expeditions, astronauts might encounter radiation from galactic cosmic rays and solar wind one day. What type of radiation and what the expected impacts on health of exposure will be to astronauts is some of the open questions amongst space agencies.

A research scientist named Jeffery Chancellor from the Department of Physics and Astronomy at A&M University in Texas, has spent many years studying the effect of radiation as portion of the 4 NASA missions. Lately, collaborating with Serena Aunon-Chancellor a physician and an astronaut and John Charles an Associate Director of NASA's Human Research Program for Exploration Research Planning (NASA), Chancellor studied the health inferences of too much exposure to space radiation in low-altitude polar orbits.

They utilized as an experiment case the MOL or Manned Orbiting Laboratory, about which expedition documents were just declassified.

The Manned Orbiting Lab was conceived in year 1963 and gone through planning from year 1965 to year 1969, on the other hand never really flew. The Manned Orbiting Laboratory was visualized as an investigational lab for human spaceflight; however it was recast as reconnaissance platform during Cold War in 1965.

Chancellor said, “It was such an exceptional orbital profile. Low altitude, polar, I could not estimate or guess what the impacts would be. Therefore, I chose to take a step back and use state of the art numerical and computational techniques to this expedition profile.”

They discovered that the minimum protection of the Manned Orbiting Lab program spacecraft and its high inclination polar orbit has left the crew at risk of high exposure to solar particle events and cosmetic radiation. Results were posted last January in Aerospace Medicine and Human Performance.

The research was backed by ODNI or Office of the Director on National Intelligence. They made extensive application of the supercomputers at TACC or Texas Computing Center.
