In a public lecture in Beijing on Thursday, the general manager of space contractor China Aerospace Science and Technology Corporation (CASC) laid out China’s space exploration program for 2030 to 2045, according to state-run news agency Xinhua. It includes Mi Yin (“Searching Sound”), a plan that involves sending spacecraft to discover exoplanets and survey how habitable they are.

For more than two decades, astronomers around the world have been searching the cosmos for galactic neighbors that resemble the Earth -- the only life-sustaining planet that we know of. Likely candidates should be located just the right distance from a solar system’s star -- colloquially known as the Goldilocks zone, not too hot and not too cold -- so that it can harbor liquid water.
