Chinese scientists have proposed a space project to survey the sky through a space-borne telescope to hunt for habitable Earth-like planets outside the solar system, about 32 light-years from Earth, the official media reported on Thursday.

The project, named Closeby Habitable Exoplanet Survey (CHES), if carried out, will be the first space mission specially designed to search for habitable terrestrial planets around nearby Sun-like stars, the report said.

The exploration of habitable planets outside the solar system is one of the key frontiers of fundamental research in astronomy.

The CHES will observe about 100 Sun-like stars 32 light-years away on a long-term survey, and will hopefully discover roughly 50 Earth-like planets or super-Earths, planets that are up to about 10 times the mass of Earth, state-run China Global Television Network (CGTN) reported.

The CHES will offer crucial clues to the issues such as ''Are we alone in the universe?'' and ''How can planets become the cradle of life?'' according to Ji Jianghui, a research professor from the Purple Mountain Observatory of the Chinese Academy of Sciences, who is the principal investigator of the CHESmission.

Ji said more than 5,000 exoplanets have been discovered and confirmed so far, including about 50 Earth-like planets in the habitable zone, but most of them are hundreds of light-years away from Earth.

''The discovery of the nearby habitable worlds will be a great breakthrough for humankind, and will also help humans visit those Earth twins and expand our living space in the future,'' Ji added.

All very well to search for habitable planets 32 light years away but shouldn't China be concentrating on landing humans on Mars in six to seven years from now ? Unless China is building a Dune-like Holtzman Engine fold-space spaceship piloted by an intelligent computer.

China can take both tasks and other space explorations at the same time, you don't have to worry about China's ability.

Absolutely, China can do both tasks at the same time but I am just curious. Is there a current or under-development Chinese equivalent of the under-development SpaceX Starship + Super Heavy spacecraft complex that can take 100 tons to Mars and is supposed to land a few humans on Mars in six or seven years ? Will China land humans on Mars before that or by that ?

China's super heavy rocket Long March 9 is under development currently and it should be ready after 2028. The rocket with 140 tons of capacity will take few astronauts to the Mars no problem. China is first to return a Mars sample in 6 or 7 years time around 2028 launch. And China plans to send astronauts to Mars on 2033, 2035, 2037, 2041 and 2043 consecutively. China intends to build a base station on Mars.

Chinese manned space is focused on moon for colonization due to its close distance and energy and oxygen content, with oxygen extraction from lunar dust already experimented on at pilot scale.

SpaceX has focused on Mars due to its water resources and capability to produce methane.

We will see which approach is more successful.

Good that it will have 140 tons of capacity but what will be its configurations, its forms ? Will it be like SpaceX Starship : reusable, having crew compartments and able to land by itself on Mars ?

China is first to return a Mars sample in 6 or 7 years time around 2028 launch.

By that time SpaceX will have landed humans on Mars and gotten them to bring many samples.

And China plans to send astronauts to Mars on 2033, 2035, 2037, 2041 and 2043 consecutively. China intends to build a base station on Mars.

When will the station be built ?

Yes and also SpaceX is focused on Mars for wider reasons : for humans to be a multiplanetary species and for I believe closeness to the resources-rich Asteroid Belt. Earth's Moon is useless in both regards. So you tell me which approach is better and beneficial ?

You should look at a solar system scale map if you think Mars is anywhere near the asteroid belt.

Moon is already essentially multiplanetary, there are very few events that could affect Earth and Moon simultaneously but not Earth and Mars.

Good luck to SpaceX if they can achieve landing humans on the Mars in 6 to 7 year, Musk can brag all the things in the world he wants like establishing human colony of at least 10000 people on Mars by 2040 some years ago put forward by him. NASA doesn't plan to send humans to Mars until 2040. Chinese Mars station should be build around late 2030s.

Okay. Now all you need is an engineer capable of going twice the speed of light to reach there in 16 years.

Or,

On teleportation, don't know what people believe here about teleportation. But let's say it's possible. Till when can we expect to crack the code ? And what are the theories ? Can we teleport ourselves to other planets ?

Now I'm curious, have SpaceX already know the way how to re-launch their Star Ship from the Mars surface? I haven't seen SpaceX send their Starship to Mars, nor even land their space craft or even bring their space craft up, and leave the Mars orbit. Not to mention that Mars has minus 70 decree celcius, I think. So how could their 'human' survive in their first Mars human mission?

Well there are events that can affect Earth and Mars.

Nearby Supernova, rogue planet entering solar system, another star coming close ect

Now this looks like a promsing telescope.

If habitable planets are found within few lighyears from the Sun, Superplanets would be not so well suited, becauese of its seceral times stronger gravity relative to earths 1G at sea level.

The perfect candidate would be a terrestrial planet similar to earth within the habitable zone and day/night periodicity (own axis rotation cycle) close to 20 hours.

to maintain orbital stability without a moon, a terrestrial planet may need to spin faster ~8-10 hour days.

Didnt really think of that aspect when you mentioned it but yeah moon is really helpful in that regard.
