Universe: China has discovered a second Earth2 min read
China’s space program is always growing and after the space station, missions to the Moon and Mars, the project is to explore new solar systems and their exoplanets . With existing technology and modern telescopes it is extremely difficult to find the presence of small Earth- like planets mainly due to its host stars, which are much heavier and brighter.
However, the Chinese mission, called Earth 2.0 , hopes that the situation will change. The mission will be funded by the Chinese Academy of Sciences and is currently completing the first design phase . If it later passes the expert review, the team will receive the funding it will need to begin building the satellite. The team plans to launch the spacecraft on a Long March rocket by the end of 2026 .
China, a new mission will leave to discover a second Earth
The future satellite will be able to carry seven telescopes that will observe the sky for 4 years . They will best observe the constellations of Swan and Lyre, the same portion of the sky that has already been scoured by the Kleper telescope. The satellite may be 10-15 times more powerful than NASA’s Kepler telescope in its sky sensing capability. It can also essentially conduct a census that identifies exoplanets of different sizes, masses and ages. The mission will provide a good collection of exoplanet samples for future research.
Of the seven telescopes, six will study 1.2 million stars over a 500-square-degree portion of the sky . Earth 2.0 will be able to locate farther stars than can be seen by NASA ‘s Transiting Exoplanet Survey Satellite , which examines bright stars near Earth. The seventh tool will be the Microlensing Gravitational Telescope to observe rogue planets, free celestial bodies that do not orbit any stars and exoplanets , such as Neptune, far from their star.
There will be a lot of data, so we need all the hands we can get. Earth 2.0 is an opportunity to enhance international cooperation . The team of Chinese scientists hopes to find at least a dozen planets of Earth 2.0 within a few years of its operations.
