China's Xuntian CSST set to map the cosmos with Hubble-scale sky coverage by 2027

China is advancing the CSST/Xuntian space telescope, a bus-sized observatory with a 2-meter primary mirror and a 2.5-billion-pixel camera designed to survey the sky from near-UV to near-IR with a field of view about 300 times larger than Hubble. Slated for launch in early 2027, it will operate in low Earth orbit co‑orbiting with the Tiangong space station and can be serviced by astronauts. An end-to-end simulation study published ahead of launch highlights potential science across cosmology, galaxies, the Milky Way, and planetary systems, including insights into dark matter and dark energy.

Hubble Telescope's End: Is Its Disappearance Nearing?

The Hubble Space Telescope, launched in 1990, is nearing the end of its operational life due to orbital decay accelerated by solar activity, with potential reentry as early as 2029. NASA has attempted to extend its lifespan, but without intervention, Hubble may soon be lost, creating a gap in space observation. However, the upcoming Lazuli telescope, funded by private sources and planned for launch in 2028, aims to succeed Hubble with advanced capabilities.

China's Xuntian Space Telescope to Reveal Universe's Secrets with Breakthrough Data Simulations

China's Chinese Space Station Telescope (CSST), also known as Xuntian, has completed a high-quality scientific data simulation, marking a key step toward its 2026 launch. The telescope features advanced optical systems with a 2-meter aperture, designed for wide-field, multi-color imaging to study galaxies, stars, and exoplanets, promising significant contributions to astrophysics and cosmology. It will operate independently and dock with China's space station for maintenance, supporting long-term space-based scientific exploration.
