Mission to Mars may be canceled?

If Kyuriositi can explore Mars at close range, the people on this issue will have to wait a little while. Manned mission to the Red Planet could be deadly. The present level of technology is not to protect the expedition from radiation, said the NASA.

Detection of cosmic radiation (RAD), mounted inside the rover Kyuriositi, had new measurements of radiation that cause NASA to review the effectiveness of the existing system of protection against radiation.

The obtained data, published in the journal Science on May 31, indicate a possible excess of the allowed rate of radiation exposure for astronauts using modern power plants.

The health of astronauts in space potentially threaten the two forms of radiation. The first threat – galactic cosmic rays (GCR), particles formed by supernova explosions and other high-energy phenomena beyond the solar system. The second threat comes from solar energetic particle (SEP), associated with flares and coronal mass ejections on the Sun.

Modern spacecraft are more protected from the sun’s energy particles than from galactic cosmic rays. Invisible streams of high energy particles can penetrate through the protective walls of modern spacecraft.

To protect astronauts from exposure to external radiation, NASA, you may have to invent a better protection.


Exposure to radiation increases the risk of cancer. Sustained effects of radiation at a dose of 1 Sv (Sievert) increases the risk of cancer by 5 percent. The margin for astronauts – 3 percent.

Detection of cosmic radiation showed that during the flight to Mars rover Kyuriositi received a daily average radiation dose equal to 1,8 milliSv. Accumulated during space travel dose, according to Cary Zeitlin of the Research Institute SwRI in San Antonio (Texas, USA), is comparable to the one that gets people in the whole body CT scan every five or six days.

“It is important to understand the radiation environment inside the spacecraft carrying humans to Mars, which is also critical for planning future manned missions,” – he said.

But it is doubtful whether the results of the study will prevent manned flight to Mars. The data obtained will help just to make certain adjustments to the mission.

Recall that the number of people willing to go to Mars Program Mars One almost reached 80,000 people . The flight and ground colony on the Red Planet will be broadcast on television. The project started in 2011. This year will be selected the first group wishing to go to space travel. The first ship will fly humans to Mars in 2022.
