NASA Trip to Mars could increase the risk of leukemia

Are you ready to travel to Mars in 2030. Think again!

In the quest of understanding our universe, the space agencies like NASA are trying to put diverse efforts which may have serious repercussions to Humans. According to a recent study by NASA, trip to Mars could increase the risk of leukemia.

The exploration of Mars has been a goal of national space program for decades. Several types of mission plans have been proposed like Opposition class, Conjunction class, or the Crocco class. But the Mars mission is giving rise to a problem for the Astronauts.

Leukemia, a group of cancers that usually starts from bone marrow and resulting in a high number of White Blood Cells is usually caused by the radiations from nuclear reactors after the large dose of Sr-90 emissions. Space is a door for those radiations to enter into our atmosphere and increasing the risk.

The study conducted by NASA warned, the Radiation exposure is one of the most dangerous aspects of traveling to Mars, which is planning to send humans to the red planet in the 2030s. The research was carried out in a mice transplanted with human stem cells.

What radiations can do to your body

The Heavy ions and low energy protons and Helium particles are highly ionizing forms of radiations, which can produce distinct biological damage compared to the X-rays and Gamma rays. There is both acute and chronic health damage to our health.

There are various after-effects, involving direct damage to DNA, indirect effects due to the generation of reactive oxygen species and changes to the biochemistry of cells and tissues and altering gene transcription and producing DNA mutations.

The space program to the Mars is being seen as the biggest threat to our heath by NASA. Several measures are thought to be taken to ameliorate the effect. Spacecraft should be constructed out of hydrogen-rich plastics rather than the aluminum. Proper shielding is to be done to reduce the risk, Water can be used for the shielding purpose and also, Asteroids could serve the purpose of shielding.

The radiations may reduce the ability of the Astronaut’s immune system to fight malignant cells that arise due to the radiation-induced mutations. The team is directed and testing to find a common dietary supplement for their ability to cope with radiations.
