SOON A FOOT ON MARS

"With the current budget or a slightly increased budget, it will take 25 years to address these issues," said retired astronaut Tom Jones. But what problem still unresolved!

You must know that Mars is located 225 million kilometers from the Earth, which requires nine months of travel.

And a move that is not without risk!

Scientists warn about the dangers that duration might represent this mission. According to them, an extended stay in space could degrade the blood vessels of the retina and thus alter the vision of the cosmonauts. They also warn against a loss of calcium in the bones, also caused by a period spent too long in zero gravity.

"We need to start focusing on some key technologies right now," said Jones. And for this former astronaut, the solution is simple: it is necessary to create nuclear propulsion systems to shorten the travel time.

NASA must find not only a solution to reduce travel time but also to avoid radiation. During the journey, astronauts could suffer as much as during an entire career.

"We do not yet have the solution for the protection of cosmic rays and solar flares," acknowledged Tom Jones. NASA experts have begun to work on technologies to develop to carry out this mission with the minimum of risk for the health of their men.

While waiting to send men to Mars, NASA continues to exploit the data collected by the Curiosity robot that has been on the planet since 2012.

Sent May 5, 2018, the probe InSight, created by the American space agency, must land on November 26 on the red planet.

It will notably study the internal structure of Mars to better understand how the rocky planets of the solar system are formed.

A new rover must be sent to Mars in 2020 to determine this time if the planet is habitable.
