This mission had already been discussed. But today, these are theto the commands that evoke it. Who detail it, even. Since they publish a white paper of some 115 pages to explain how they intend to go in search of a “Earth 2.0”. By relying on a new generation space observatory whose launch is scheduled for the end of 2026. The mission ” AND “ — for “Earth 2.0” — as they baptize it. Because the objective is there: to find a .

Hence the idea of first identifying an Earth 2.0 before starting to look for traces of life.
At the base of the project, seven telescopes which, like thefrom NASA, will be “stationary” to for four years. Six of them — each 30 centimeters in diameter — will be aimed at the same region of the sky as the Kepler has already observed. To find your way around faster.

The seventh telescope of the ET mission will face the center of our. With the aim of identifying the phenomena of gravitational microlenses which could in particular betray the presence of a few wandering exoplanets. Planets that are no longer attached to a star. And in fact, particularly difficult to flush out.
More than a dozen Terres 2.0 in sight

Also those whose orbits differ from that of our Earth and therefore, the possible wanderers.
Chinese researchers have already conducted some simulations. They announce that the ET mission should be able to detect some 29,000 new exoplanets. Among them, nearly 4,900 the size of our Earth. And, assuming that the rate of occurrence of rocky planets similar to ours is 10%, possibly between 10 and 20 Earths 2.0. All from 2030, therefore.
Once these Earths 2.0 have been identified, it will still be necessary to study the composition of theirand to determine if water can flow on their surface. Next, researchers will have to look for biomarkers — such as methane or oxygen — or — like transmissions — which could indicate that life developed there.
The white paper published by the researchers in charge of the project also tells us that the ET mission will not stop there. It will also target tens of thousands of objects in ourof the or some .
