Colonizing Mars or exploring deep space may be more difficult than expected, according to the recent study analyzing cancer-causing cosmic rays.
Frank Cucinotta, a health scientist, collaborated with Eliedonna Cacaoat of the University of Las Vegas, to study cosmic rays effects. In the research disclosed in the Journal Nature, the researchers studied the results of former analysis of tumors in mice and noticed the animals were as twice vulnerable to cancer in deep space as initially believed.
The flaw in previous studies
The study team believes that former studies didn’t recognize that cosmic rays can move from primary cells to secondary, destroying the DNA, converting them into cancerous cells.
Shielding technique was said to possess just modestly decreased the intensity of radiation the mice were given out to. Cosmic rays can also cause nerve damage, cataracts, and problems with circulating blood, and possess energetic atoms and subatomic particles that come from the explosion of black holes and stars.
Astronauts face higher radiations more than those on Earth, as the atmosphere of the planet gives a natural guide from dangerous energy. Crew members aboard the ISS also benefit from the Earth’s magnetic field which moves cosmic rays direction away from the orbit of the Earth.
Significant differences may abound between the cancer rates in humans and mice; the research findings can stop deep-space exploration by man in the future. Various organizations are sourcing means of withstanding the effects of radiation in space, involving satellite that can divert radiation, and a radiation-absorbent vest.
NASA is working to launch human missions to Mars by 2030, and China declares it aims at getting their soon, starting with its Mars landing mission in 2020.
