Rocket Report: A rare Falcon 9 scrub; is it just about Vulcan's time to shine?

Welcome to Edition 9.14 of the Rocket Report! This week, the big news centers around United Launch Alliance's Vulcan rocket, which appears to be on the verge of launching. A no-earlier-than launch date of October 29 for the return to flight mission of an Amazon Leo flight has been announced, along with another Amazon Leo mission slated for this year.

If the solid rocket boosters perform as expected, Vulcan could experience a significant boost in launch frequency next year.
