SpaceX is gearing up to launch a third top-secret spacecraft for the U.S. government, a mission the company calls "Zuma" but has said little else about.
The mystery satellite is tentatively slated to lift off from Florida's Kennedy Space Center on Friday, November 17, after 8 p.m. ET though possibly as late as 10 p.m. ET. SpaceX plans to broadcast the launch live via YouTube starting about 15 minutes beforehand. (You can watch the video feed at the end of this post.)

SpaceX, the aerospace company founded by tech mogul and Mars-colonizing hopeful Elon Musk, initially planned to launch the clandestine spacecraft on Wednesday. However, the company delayed the launch multiple times.
The reason for the delay doesn't appear to be weather-related, given the current forecast. Previous delays were made "to allow engineers to complete additional mission assurance work," according to Spaceflight Now. SpaceX said in later statements that a fairing (i.e. rocket nosecone) inspection "for another customer" caused the company to stand down, and that it "will take the time we need to complete the data review and will then confirm a new launch date" — so a Friday lift-off may be canceled.
SpaceX has loaded the Zuma payload atop a reusable Falcon 9 rocket earlier this week.
When it lifts off, the Falcon 9's roughly 133-foot-tall booster — the largest and most expensive part — will lug Zuma a few dozen miles above Earth, then detach and attempt to land at Cape Canaveral Air Force Station. Right after separating from the booster, a smaller second-stage rocket will fire up and finish pushing the secret payload into orbit.

Since then, the vacuum of information has led to evolving speculation about the details and purpose of the launch. NASA Spaceflight's thread about Zuma and a Nov. 15 story from Spaceflight Now have floated a number of ideas and theories:
- If the National Reconnaissance Office isn't behind Zuma (although Ars Technica claims it is the NRO's), the payload may be for the Central Intelligence Agency, the National Security Agency, or some other non-military U.S. government agency.
- Estimates of Zuma's orbit around Earth may be good for spying on China and North Korea, though its trajectory can't be confirmed until after launch.
- The predicted orbit is similar to that if the NRO's USA-276 (or NROL-76) satellite. With Zuma launching around 8:00 p.m. ET, it could go into orbit less than 10 minutes behind USA-276 — very close in terms of outer space.
- This has led some to suggest Zuma may be a refueling mission for USA-276, or part of a spy satellite constellation or program associated with that mission.
