Search for exoplanets included in the list of scientific goals of future Chinese missions

(ORDO NEWS) — The Chinese Academy of Sciences has decided on a set of space missions, from which several of the most interesting missions will be selected after the completion of the competitive review for sending between 2026 and 2030.

Of the 13 proposed missions, only 5 to 7 missions will be approved for launch, reports spacenews.

Three of these missions, Enhanced X-ray Timing and Polarimetry (eXTP), Discovering the Sky at the Longest Wavelength (DSL), and DArk Matter Particle Explorer-2 (DAMPE-2), will conduct astrophysical and astronomical research.

The next four of the proposed missions, named Chinese Heliospheric Interstellar Medium Explorer (CHIME), SOlar Ring (SOR), Solar Polar-orbit Observatory (SPO) and Earth-occulted Solar Eclipse Observatory (ESEO), aim to study the physics of the Sun.

Four possible future missions are aimed at studying the Earth (Low-Earth orbit Climate and Atmospheric Components Exploring Satellites (CACES), Ocean Surface Current multiscale Observation Mission (OSCOM)), as well as other objects of the solar system (studying Venus – the Venus Volcano Imaging and Climate mission Explorer (VOICE);

Finally, two missions will search for habitable exoplanets in space:

– The Closeby Habitable Exoplanet Survey (CHES) will use relative astrometry techniques with a resolution of the order of a few microarcseconds to study 100 sun-like stars located at distances of no more than 33 light-years from Earth;

– The Earth 2.0 (ET) mission will conduct a targeted search for terrestrial planets in the same orbits around sun-like stars as the Earth around the Sun, using a seven-telescope instrument that will be located at the second Lagrange point of the Earth-Sun system.

Each of the 13 missions proposed under the program will be peer-reviewed based on criteria such as budgetary funding requirements, level of technology readiness, and the speed with which technology solutions required for the mission can be implemented within the next 15th five-year China’s plan, which will start in 2026.
