This mission had already been discussed. But today, these are theto the mandates that evoke it. Who details it, even. Since they publish a white book of about 115 pages to explain how they intend to go in search of a “Earth 2.0”. Relying on a new generation space observatory whose launch is scheduled for the end of 2026. The mission ” Y “ — for “Earth 2.0” — as they baptize it. Because the goal 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 that, like theof NASA, it will be “stationary” a For four years.

The seventh telescope of the ET mission will look toward the center of our. With the aim of identifying gravitational microlensing phenomena that could reveal, in particular, the presence of some wandering exoplanets. Planets that are no longer attached to a star. And, in fact, particularly difficult to remove.

Chinese researchers have already run some simulations. They announce that the ET mission should be able to detect about 29,000 new exoplanets. Among them, almost 4,900 the size of our Earth. And, assuming the rate of appearance of rocky planets similar to ours is 10%, possibly between 10 and 20 Earth 2.0. Everything from 2030, therefore.
Once these 2.0 Earths have been identified, it will still be necessary to study the composition of theirand to determine if water can flow on its surface. Next, the researchers will have to look for biomarkers, such as methane or oxygen, or — as transmissions — which could indicate that life developed there.
