China launched the Shenzhou 23 spacecraft with three astronauts to the Tiangong space station, including one planned for a yearlong stay to investigate long-duration flight effects on humans. The launch overlaps with biological experiments aboard Tiangong, notably the shipment of synthetic human embryos to study early development and reproduction in space. These investigations broaden the station’s scientific agenda and could involve crew support or monitoring.
