Does anyone know where these photos were taken?

Orbital ATKís Pegasus XL rocket is being prepared to launch NASAís Ionospheric Connection Explorer, or ICON mission. The rocket is being prepared in a facility at Vandenberg Air Force Base (VAFB) in California.

That's OATK's Vehicle Assembly Building on the north base side of VAFB. It's a nondescript building with two side-by-side bays for doing horizontal assembly and integration of some of OATK's rockets.

VAFB Building 1555 is used solely for processing Orbital ATK's Minotaur-C and Pegasus-XL. All other Minotaur and defense target products use VAFB Building 1900.

Both of which can be seen in a new photo from the Minotaur-C mission thread.

Mission Update Nov. 3, 2017 - NASA is postponing launch of the Ionospheric Connection Explorer (ICON) until 2018. The mission was previously planned to launch Dec. 8, 2017, on an Orbital ATK Pegasus XL rocket from the Reagan Test Site on Kwajalein Atoll in the Marshall Islands. NASA and Orbital ATK need additional time to assess a separation component of the rocket. More information on a revised launch date will be provided once it becomes available.

Speculating,  maybe this separation component has something to do with SpaceX Zuma component.  Explosive bolt testing might have found a bad batch?

Fairly[1] far fetched.  Not every thread is about SpaceX.

1 - see what I did there?

Spacex doesn't use explosive bolts

Seems that this missionís launch site is now a toss-up: because of the lengthy delay the missionís experiencing, analyses are now being done to determine if it can be launched out of the Cape. Kwaj is a very busy place, and it may be very difficult to find a slot in its schedule. It all depends on mass - the s/c came in at the low end of its estimated mass. That makes a Cape launch feasible - if the solution to the current issue doesnít drive up the total LV mass. No firm decisions yet...

The mission is not restricted to solely US launch Sites, although that is generally preferred. It can also launch from many sites in allied nations.

An example of an "allied nation launch" was from Gran Canaria in the Spanish Canary Islands.

In the case of this mission the two launch site options I cited are the only two launch site options on offer. While Pegasus has indeed launched from other locations, NASA will not, unless there are special conditions identified by the launch customer. Historically, all NASA Pegasus missions have launched from US-controlled territory (Wallops, VAFB, EAFB, RTS, CCAFS). ICON will follow this model.

Bad example: Minisat 01 was a Spanish Space Agency payload, so they specified a Spanish launch site. Celestis was a commercial customer on that flight and didn't really care where it launched from.
