Summary

The federal government must not buy human spaceflight transportation from a foreign company unless three things are true: no U.S. government-run human spaceflight is available, no U.S. commercial provider is available, and the foreign company is a qualified foreign entity. The law defines: "commercial provider" — a private company that offers human spaceflight; "qualified foreign entity" — a foreign company that meets safety rules and is not barred by other laws; "United States commercial provider" — a U.S.-organized company more than 50% owned by U.S. nationals. It does not stop the NASA Administrator from working with foreign companies to keep flights safe and to keep the ISS operating. Congress also says the United States must keep an uninterrupted ability to fly people and operate in low-Earth orbit and beyond because this ability is essential for national security and U.S. leadership in space.
