晨昏线 CHXLive is a prominent Chinese platform dedicated to tracking global space dynamics. It offers an extensive overview of upcoming launch schedules, mission archives, details about rockets and space agencies, and a curated collection of space news. Named after the terminator line that depicts the transition between day and night on a planet, the platform reflects humanity's gaze towards space through each significant ignition.

CHXLive provides users with a timeline of recent launches, capturing critical information such as countdowns and launch statuses in both Beijing time and UTC. Users can also explore individual rocket missions, including their trajectories and launch sites, alongside significant events in deep space and observational industries.

The website aggregates data from reputable public sources, like Launch Library 2 and Spaceflight News API, ensuring up-to-date information. As a non-commercial personal project, CHXLive not only serves as an educational resource for space enthusiasts but also welcomes feedback and collaboration through its contact channels.
