NASA Advised To Rethink Astronaut Radiation Exposure Limits
NASA Advised To Rethink Astronaut Radiation Exposure Limits

Report: NASA Should Update Astronaut Radiation Exposure Limits, Improve Communication of Cancer Risks “The report recommends that NASA proceed with its proposed single standard dose limit for all astronauts, which is based on “risk of exposure-induced death” (REID) calculations for a 35-year-old female (who is considered most susceptible to radiation-induced cancer risk). Currently, men and women astronauts have different allowable doses of radiation, based on their reported relative susceptibilities to […]

Radiation Risk and Exploring Mars
Radiation Risk and Exploring Mars

Collateral damage from cosmic rays increases cancer risks for Mars astronauts, University of Nevada Las Vegas “Galactic cosmic ray exposure can devastate a cell’s nucleus and cause mutations that can result in cancers,” Cucinotta explained. “We learned the damaged cells send signals to the surrounding, unaffected cells and likely modify the tissues’ microenvironments. Those signals seem to inspire the healthy cells to mutate, thereby causing additional tumors or cancers.” Cucinotta […]

ISS Cosmic Radiation Results Published

MATROSHKA Experiment: Space Travel is a Bit Safer Than Expected, Institute of Nuclear Physics of the Polish Academy of Sciences “Analysis of data from the MATROSHKA experiment, the first comprehensive measurements of long-term exposure of astronauts to cosmic radiation, has now been completed. This experiment, carried out on board and outside of the International Space Station, showed that the cosmos may be less hostile to space travellers than expected.”

Is There a Radiation Gender Barrier at NASA?

Female Astronauts Said To Face Discrimination Over NASA’s Space Radiation Concerns, Huffington Post “Depending on when you fly a space mission, a female will fly only 45 to 50 percent of the missions that a male can fly,” Peggy Whitson, the former chief of NASA’s Astronaut Corps, said. “That’s a pretty confining limit in terms of opportunity. I know that they are scaling the risk to be the same, but […]

Important Research Results NASA Is Not Talking About (Update)

Houston, We Have Another Problem: Study Shows that Space Travel is Harmful to the Brain “The possibility that radiation exposure in space may give rise to health problems such as cancer has long been recognized. However, this study shows for the first time that exposure to radiation levels equivalent to a mission to Mars could produce cognitive problems and speed up changes in the brain that are associated with Alzheimer’s […]

False Claim of NASA Participation in Wrinkle Research (Update)

False Claim of NASA Participation in Wrinkle Research “According to information provided by NASA PAO, the “AS10″ food substance mentioned in this news story is not a NASA food product. This food substance may have been developed by someone else using a product developed originally by AmeriSciences but NASA itself has not used any material or food substance described in these various news stories related to wrinkles nor is it […]

NASA OIG Reports on Problems With ISS Radiation Health Research

NASA’s Development of Radiation Monitoring Instruments for the International Space Station “This Office of Inspector General (OIG) review found that NASA has poorly managed the development of these replacement radiation monitoring instruments. Specifically, total estimated ARI Project costs increased approximately 62 percent, from $16 million to $26 million; the Project has been de-scoped and will not include all planned elements; and delivery of the new instruments has been delayed by […]
