China’s Einstein Probe, a spacecraft designed to detect X-ray emissions from violent cosmic phenomena, was successfully launched on January 9th, 2024. This mission marks another significant step in China’s dedicated space science efforts.
The Einstein Probe will spend a minimum of three years observing distant interactions such as tidal disruption events, supernovae, and gravitational wave events. Operating in a 600-kilometer altitude, 29-degree inclination orbit, the probe will utilize the Wide-field X-ray Telescope (WXT) with lobster eye-inspired optics.
With the ability to combine 12 modules, the WXT provides an extensive field of view, covering 3,600 square degrees. This wide range will enable the probe to observe X-ray events more deeply and widely than previous missions.
Contributing to this mission, the European Space Agency (ESA) has supported the testing and calibration of the detectors and optical elements of the WXT. In exchange for their contributions, the ESA will receive 10% of the data generated by the Einstein Probe.
One notable feature of the probe is its onboard data processing and autonomous follow-up capabilities. These features allow for prompt study of short-lived events, contributing to faster and more efficient analysis of cosmic phenomena.
The launch of the Einstein Probe came just days after China successfully launched four Tianmu-1 GNSS radio occultation satellites. This event demonstrates China’s continued commitment to space exploration and its growing presence in the field of scientific research.
Looking ahead, China’s next high-profile mission in 2024 will be the Chang’e-6 lunar far side sample return mission. In preparation for this mission, the launch of the Queqiao-2 lunar relay satellite will be necessary.
With these recent achievements and future plans, China is establishing itself as a key player in space science and exploration. The Einstein Probe, along with other missions, will contribute to expanding our understanding of the universe and uncovering its mysteries.
