US Space Force 5 years later: What has it accomplished so far, and where does it go from here?

The emblem of the United States Space Force.

The U.S. Space Force celebrates its fifth anniversary today.

The service was formally established on Dec. 20, 2019, when President Donald Trump signed it into law with the National Defense Authorization Act, the bill that allocates U.S. military spending each year. Since then, the U.S. Space Force has grown to nearly 15,000 servicemembers and civilian personnel. In its fifth year, Space Force has overseen astronaut launches from its facility at Florida's Cape Canaveral Space Force Station and has even seen one of its own active Guardians, as Space Force members are known, launch into space.
