Christina Koch, veteran of six spacewalks outside the International Space Station — including the first all-female excursion — joined a Russian commander and an Italian flight engineer for a fiery plunge to landing in frigid Kazakhstan early Thursday, setting a new record for the longest single flight by a female.

The final flight of a Delta 2 rocket, a mainstay of the U.S. launch industry for nearly 30 years, began at 6:02 a.m. PDT (9:02 a.m. EDT; 1302 GMT) from Vandenberg Air Force Base in California with NASA’s ICESat 2 Earth science satellite.

An Ariane 5 rocket lifted off Thursday at 2345 GMT (7:45 p.m. EDT), flying from a French Guiana launch pad to geostationary transfer orbit with the ViaSat 2 and Eutelsat 172B communications satellites.
