For this question, block-quoting all of the relevant information would be unwieldy (even for me) so I will just link four articles (plus one quoted section from the last item):
- NASA Spaceflight 16-Oct-2017 SpaceX adds mystery “Zuma” mission, Iridium-4 aims for Vandenberg landing
- NASA Spaceflight 11-Nov-2017 SpaceX static fires Zuma Falcon 9; engine test anomaly no issue for manifest
- Florida Today 14-Nov-2017 SpaceX ready for mystery 'Zuma' launch from KSC and landing at Cape Canaveral
- Spaceflight Now 14-Nov-2017 Top secret ‘Zuma’ mission puzzles satellite trackers
A top secret payload developed in secrecy for the U.S. government is set to ride into orbit from Florida’s Space Coast aboard a SpaceX Falcon 9 rocket Thursday.
Known only by the codename Zuma, the payload is likely heading for an orbit less than 1,000 miles in altitude, and perhaps much lower. The existence of the mission was not revealed until it was disclosed in regulatory filings last month.
A disclosure so close to launch is rare in the space industry, and little information about the mission has been released in the last few weeks. Clandestine spacecraft owned by the National Reconnaissance Office — the U.S. government’s spy satellite agency — receive codenames years before they lift off. They’re also listed in public procurement documents and launch manifests. (emphasis added)
It looks like NASA was going through normal procedures to approve the use of "used rockets" ("once-flown Falcon 9 booster that lofted a payload to Low Earth Orbit (LEO)" item 1.) to supply the ISS, but I'm not sure this was complete.
Question: Did the sudden appearance of Zuma on the schedule expedite this approval, by "bumping" NASA from business class and encouraging them to accept an empty seat in coach (putting CRS on pre-flown boosters)? Or would NASA have approved the use of once-used-to-LEO F9's in time for the CRS launches anyway?
Bonus: Will Zuma appear on the mission patch?
