Live coverage: Soyuz crew lands in Kazakhstan

Christina Koch, veteran of six spacewalks outside the International Space Station — including the first all-female excursion — will join a Russian commander and an Italian flight engineer for a fiery plunge back to Earth early Thursday, setting a new world record for the longest single flight by a female astronaut.

A Russian-built Soyuz rocket lifted off from South America at 0848 GMT (4:48 a.m. EDT) Tuesday with two new navigation satellites for Europe’s Galileo system, readying the network for initial operating capability later this year.

NASA awarded the so-called ‘Lunar Terrain Vehicle Service’ contract and classified it as an “indefinite-delivery/indefinite-quantity, milestone-based LTVS contract with firm-fixed-price task orders.” The agency said it “has a combined maximum potential value of $4.6 billion for all awards.”
