Chinese Exoplanet Mission, "Earth 2.0" mission in planning stages. Options

[StargazeInWonder]

China is planning an exoplanet search which would be, in many ways, a sequel to Kepler. By observing the same stars that Kepler observed, it provides opportunities to cinch more candidate earthlike planets in a shorter amount of time, by finding second, third, fourth, etc. transits of exoplanets with periods ~1 year which might have had only 1 or 2 transits observed by Kepler. This would also give us more accurate frequency estimates for terrestrial planets with longer orbital periods of ~2 years.

Moreover, the mission would have a much wider field of view than Kepler, and therefore observe many stars that Kepler did not, and in an entirely separate modality, will conduct a search using the microlensing method, which is more apt for finding planets in orbits like those of Uranus and Neptune.
