Thomas Pesquet returned to Earth on Tuesday after spending 200 days aboard the international space station.

During his mission, the astronaut conducted numerous experiments intended to collect information to prepare for future trips to the Moon and Mars.


After 200 days aboard the International Space Station, astronaut Thomas Pesquet finally returned to Earth on Tuesday morning.

His stay in the International Space Station (ISS) had scientific aims intended to better understand what is happening in space.

In the sights of scientists: take advantage of the station to test devices and conduct experiments in weightless conditions.

Prepare the next missions to Mars

Many manipulations were carried out on board the ISS by Thomas Pesquet and his teammates of the Alpha mission.

These are complex operations that can only be carried out on board the station thanks to weightlessness.

These experiments provide information to chemists, biologists and physicists.

The crew brought back to Earth 250 kilos of material and results, but most of the work carried out by Thomas Pesquet and his mission is used to imagine the space exploration of tomorrow.


Return of Thomas Pesquet: "their body is weakened after six months in zero gravity", assures François Forget

The Frenchman, for example, tested a device against solar storms, a sleep band or even a virtual reality headset to simulate the control of a robot remotely, for example on the planet Mars.

We know that NASA hopes to return to the Moon from 2024 with the aim of setting up a base there for longer and more regular missions.

All this, Thomas Pesquet knows.

He also tweeted before his departure from the ISS "Next time, the moon?", As if to make it clear that we had not finished hearing about him.
