The Space Force says it changed the nickname of a GPS navigation satellite launched in June from Columbus to instead honor Matthew Henson, a Black explorer on the first expedition to the North Pole more than a century ago, “to acknowledge a fuller history of courageous explorers and pioneers.” The military’s next GPS navigation satellite, set for launch Friday night, is nicknamed Sacagawea.

A Minotaur 4 rocket made up of five solid-fueled rocket motors delivered a U.S. military satellite tracking craft into an equatorial orbit early Saturday after lifting off from Cape Canaveral.
