SpaceX goes for a launch doubleheader this weekend

Ars Technica ------- It's a big weekend for SpaceX, the California rocket company that has already had a big year. On Friday, the company will attempt to launch BulgariaSat-1, a commercial communications satellite, to a geostationary orbit. On Sunday, the company will attempt to launch a second batch of Iridium satellites into low Earth orbit. If successful, this weekend would put the company on pace for a record-smashing number of missions this year. The BulgariaSat-1 launch was delayed from earlier this week due to a payload fairing issue, but that appears to have been resolved. The flight is notable because it marks only the second time the company has flown a "used" rocket back into space. The five-month turnaround on this booster has been much shorter than SpaceX's first reflight in March—this first stage was last used during a January 14th launch from California.
