On China's space station, scientists will study some of Earth's earliest organisms

A large T-shaped space station is seen from above with Earth below it.

China's space station is set to host a scientific experiment aimed at assessing the viability of Earth's early life forms in a simulated cosmic environment.

China launched the Tianzhou 7 cargo spacecraft on a Long March 7 rocket from Wenchang Satellite Launch Center on Jan. 17. It arrived at Tiangong space station just over three hours later, successfully docking with the core module.
