T+19: SpaceX’s Manifest, Flight-Proven Hardware, Blue Origin Updates, and Antares’ Engines

SpaceX has a busy manifest as they close out 2016, including SES-10 which will fly with a “flight-proven” first stage. A few bits of info have come out regarding Blue Origin’s future plans—including flying diverse payloads on New Shepard, and construction of their factory in Florda. Antares’ return-to-flight launch date is still a mystery, and I have a theory about its future engines.
