28 July 2016 12:33 Washington, July 28 (Prensa Latina) astronauts involved in the Apollo missions, ie on travel beyond Earth’s magnetosphere, have a higher risk of dying from heart disease, published today in the journal Scientific Reports.
The study, conducted by scientists at the University of Florida in the United States, indicates that 43 percent of the cosmonauts who died of cardiovascular diseases, traveled to deep space as part of the lunar missions and were exposed to high levels of radiation galactic cosmic
of the 24 men. who were in the Apollo lunar missions, eight are dead and seven were included in the study. One of them, Edgar Mitchell, died after completing the analysis of the data.
According to the lead author of the research, Michael Delp, this is the first study investigating the deaths of the Apollo astronauts. “So far, very little was known about the effects of deep-space radiation on human health, particularly in the cardiac system.”
To carry out the inquiry, the scientists exposed mice to the same type of radiation that the Apollo astronauts. After six months-the equivalent of 20 years humans-animals showed a deterioration of the arteries, one of the main causes of the development of atherosclerotic cardiovascular disease in people.
“Data analysis in mice showed that radiation from deep space is detrimental to vascular health, “he said Delp.
in addition, in such explorations, far from the protection of the magnetic field of the Earth, humans are exposed sources of ionizing radiation, and the Van Allen belts, capable of damaging DNA. In addition to cosmic rays, he said.
The Apollo program ran from 1961 to 1972, with 11 manned space flights between 1968 and 1972. Nine of them were beyond Earth orbit in deep space
This mission is well known by landing men on the moon.; and the failed mission Apollo 13 that inspired the popular 1995 film Ron Howard
