DAMPE has impressed the scientific community with its precise measurements of the energy spectra of cosmic ray electrons, protons, and galactic cosmic ray (GCR) helium. Its follow-up star, DAMPE-2, will have major improvements dedicated to detecting possible signatures of electrons/positrons from gamma rays and dark matter annihilation or decay, new spectral structures of GCRs over 100 TeV, and correlations with gravitational wave events, tidal Interruptions and transients associated with high-energy neutrinos.
3) Very Long Wavelength Astronomical Observation (DSL) Mission
The DSL mission, consisting of a linear array of microsatellites placed in orbit around the moon, will open a new window for astronomical radio observations at frequencies below 30 megahertz, with great potential for the latest and unexpected discoveries, as well as for planets and stars , galaxies, galaxies and various astrophysical processes of supermassive black holes provide new insights. It will also make high-precision measurements of all-sky regions with minimal systematic error, exploring the early days of the universe by observing the redshifted radio signals of neutral hydrogen in the dark ages of the universe after the Big Bang, and the dawn of the universe when the first stars and galaxies were formed. history of the universe.

4) The Near Habitable Exoplanet Exploration (CHES) mission
CHES is committed to discovering terrestrial planets near solar-type stars in the wavelength range of 500-900 nm with ultra-high-precision relative astrometry with an accuracy of 1 μas. There are two main scientific goals: search for terrestrial planets in the habitable zone around 100 FGK stars; and further survey and census nearby planetary systems.
5) Earth 2.0 (ET) mission
ET is a wide-field, ultra-high-precision optical space observation mission, mainly composed of six transit telescopes and one microlens telescope. ET will enable the first measurements of the occurrence rate and orbital distribution of Earth-sized planets, including some elusive Earth-like planets orbiting stars like our sun.
The field of solar physics
6) Solar Orbiting Exploration (SOR) mission
The SOR is proposed to be deployed to monitor and study the Sun and its inner heliosphere from 360 degrees in the ecliptic plane. This major mission will deploy three detectors 120 degrees apart in a 1AU orbit around the sun. SOR aims to study the origin of solar cycles, solar outbursts and severe space weather using the necessary in situ observational instruments and imagers.
7) Solar Polar Orbit Observatory (SPO)
SPO will take an unprecedented direct image of the sun's magnetic poles, and the probe will fly in a small elliptical orbit with a high inclination of 80 degrees nearly perpendicular to the ecliptic plane. SPO will reveal the origin of the solar magnetic field activity cycle that shapes the human living environment, determine the generation mechanism of the high-speed solar wind connecting the sun and solar system celestial bodies, and build a data-driven global heliospheric numerical model as the data basis for space weather forecasting.
8) Earth Covered Eclipse Observatory (ESEO)
Deploy a solar space telescope at the L2 point of the Sun-Earth Lagrange to detect the inner corona using Earth's occultation. ESEO, as a small mission, could be very useful for shedding light on the early stages of coronal outbursts within the Sun and the subsequent response of Earth's far magnetotail after being "shocked" by the solar wind.
9) China Heliospheric Interstellar Medium Explorer (CHIME)
The CHIME program is deployed at a distance of 3 AU from the sun. For the first time, in situ measurements will be carried out in the high-density region of primordial interstellar gas and dust at a distance of 2-3 AU from the sun, and the global high-energy center of the outer boundary of the heliosphere will be obtained. Sex Atom Image. CHIME will be launched into an elliptical heliocentric orbit with about 1AU at perihelion and about 3AU at aphelion.

10) E-type Asteroid Sampling Return (ASR) mission
ASR's goal is to detect the E-type asteroid 1989 ML and will collect samples from three different locations on the asteroid before returning the samples to Earth. An in-depth study of the collected samples will reveal the evolution of the early solar system nebulae in the first 10Ma years under extremely reducing conditions. In addition, by comparing with samples of C-type asteroids Ryugu and Bennu, both formed outside the solar system, it is expected to deepen the understanding of the formation of the dichotomy of the solar system. The whole task will take about 4 years to complete.
11) Venus Volcano Imaging and Climate Exploration (VOICE) mission
VOICE is a Venus orbiting exploration mission that will operate in a near-polar orbit about 350 kilometers from Venus to investigate Venus' geological evolution, atmospheric thermochemical processes, surface-atmosphere interactions, habitable environments and clouds s life.
12) Climate and Atmospheric Composition Exploration Satellite (CACES)
The small mission consists of two satellites in sun-synchronous orbits. It focuses on baseline climate variables and atmospheric composition observations. CACES will provide a deeper understanding of how greenhouse gases affect and respond to climate change and weather disasters, a major challenge in Earth system science, and provide guidance for China's carbon emissions calculations in 2028 and carbon peaking in 2030 and carbon emissions in 2060. Neutralization goals provide support.
13) Ocean Surface Current Multiscale Observation Mission (OSCOM)
Based on satellite Doppler oceanography, OSCOM is dedicated to cutting-edge research in ocean multiscale dynamics and energetics. Simultaneous observations of ocean surface current (OSC), ocean surface vector wind (OSVW) and ocean surface wave spectrum (OSWS) by Doppler scatterometer (DOPS) will provide insights into ocean sub-mesoscale nonequilibrium dynamics, multiscale processes, Contribute to research on mass/energy exchange between the ocean and the atmosphere, biogeochemical cycles, and climate change.
