Four commercial space fliers who launched from NASA’s Kennedy Space Center on Axiom’s second private astronaut mission Sunday arrived at the International Space Station on a SpaceX crew capsule Monday to start an eight-day stay full of scientific experiments, student outreach events, and sightseeing.

The sixth in a series of environmental monitoring satellites jointly developed by China and Brazil successfully launched Dec. 20 on top of a Long March 4B rocket.

A Russian Soyuz rocket rolled out to a launch pad Monday at the Baikonur Cosmodrome in Kazakhstan, ready for final inspections, checkouts and fueling before liftoff Thursday with a Progress supply ship bound for the International Space Station.
