Seems plausible for Worldview Legion or NROL-174, but I haven't found anyone making "let's go" posts, so no clear association.

There's a dogleg: the ascent is on a 201 deg heading, while the 2nd stage splash zone is aligned to 192 deg heading. (I think the latter is still consistent with a sun-sync orbit, right?)
Interested in your thoughts...

Trajectory goes to SSO, which matches this flight

Thanks, zubenelgenubi, it looks like you’re a winner:

USSF-62 launched successfully earlier today.

Is this the next Vandenberg Falcon 9 launch?  My bold:
Quote from: Maxar Technologies tweet
Our first two WorldView Legion satellites are being prepared for a mid-April launch. Once operational, they’ll provide high-resolution #satelliteimagery for our customers’ critical missions. See what’s coming: https://maxar.com/worldview-legion

[Apr 2]

Or, will it be Starlink 8-2 or 7-19?

Cross-post:
Here are a couple NGA Space Debris notices that I don't know what they are. They are not necessarily related to each other, though they came out around 15 minutes apart. I don't know whether either or both are even SpaceX.

The first is Vandy.  The second is in the Eastern North Pacific running from well off the coast of California up to off the coast of British Columbia.

Which first stage will be used for this launch?  (semi-rhetorical question)

Falcon 9 first stages are apparently now cleared for use up to twenty times for non-human spaceflight missions, although that number is apparently more restricted for Cargo Dragon and Cygnus than these other payloads.

Available first stages, with UTC date of most recent recovery:
1061.20   Feb 23
1063.18   Mar 11
1075.11   Mar 19

Edit May 1: It's B1061.20.

Possibility B1061.20?:
Another F9 (either 1060 or 1061) will fly for the 20th time next week.

May there be many boosters hitting 20 or 30 or 50, with an unbroken success streak. Kudos to the team!

Another one next week!

DigitalGlobe is the name of the company who was originally developing the WorldView Legion constellation. Maxar acquired DigitalGlobe in 2017.

This explains why we had no launch announcement from SpaceX, when they announced the Starlink 6-51 launch, also on April 17, this afternoon EDT. 🤔

Launch delayed long enough not to keep Go Beyond at sea.

If the delay grows beyond a few days, SpaceX may slide in a Starlink launch instead.
