NASA is sure enough that Boeing and SpaceX can safely launch astronauts to the International Space Station by early 2019 to hold off paying Russia to keep flying U.S. crews to the research complex, and one official says a deadline to order parts for new Russian Soyuz crew capsules may have already passed.

SpaceX is gearing up for the next big leap in the development of the next-generation Starship heavy-lift launch vehicle with a test flight to more than 40,000 feet over the Texas Gulf Coast as soon as Tuesday.

Six satellites built in France for OneWeb are set for blastoff Wednesday from French Guiana, the first of at least 21 launches using Russian-made Soyuz rockets to haul more than 600 of the refrigerator-sized craft to orbit for global broadband service.
