That document is from February 2017. According to this November doc, https://www.nasa.gov/sites/default/files/atoms/files/2017_11_29_csli_manifest_list.pdf the ELaNa-XVIII secondary payloads manifest is ELFIN, DAVE, and SurfSat. IT-SPINS and ChefSat went elsewhere.
The ICESat-2 project is proceeding to integration and testafter problems with lasers within the primary instrument—theAdvanced Topographic Laser Altimeter System (ATLAS)—caused NASA to delay the launch readiness date from June2018 to October 2018. This represents a 17-month delaybeyond the original baseline and a 4-month delay beyondthe rebaselined date set in 2014. However, the project isworking to an earlier, September 2018 launch readinessdate.

In @NASA's Building 8337 at @30thSpaceWing, technicians and engineers cleaned and took samples from the payload fairing that will protect @NASA_ICESat2 🛰️ during launch. Liftoff atop a @ulalaunch Delta II 🚀 is scheduled for Sept. 12, 2018. More photos: go.nasa.gov/2LFuioJ
Heads up! The ULA #DeltaII rocket slated to launch NASA’s @ICESat-2 mission is vertical on the launch pad at Vandenberg AFB! See you in Sept as we launch this important Earth science mission – the final for the storied #DeltaII. Photos: @NASA_LSP @NASA_Edge
3 months ahead of launch? Interesting.
Quote from: Lar on 06/07/2018 08:27 pm3 months ahead of launch? Interesting. they typically do that at VAFB. I dont remember the main reason but there is greater longitivtiy when vertical at the pad. Also because they are cleaning out and vacating Delta-II facilities for FAI (Firefly Aerospace Inc.) to move into as they become disused.

Also because they are cleaning out and vacating Delta-II facilities for FAI (Firefly Aerospace Inc.) to move into as they become disused.There have been Delta's going vertical on the pad as much as six (6) months (or more) before the launch. Sit-time for the core stage is almost unlimited.
After launching 154 missions, the @ulalaunch #DELTAII will fly its final this fall from Vandenberg with NASA's #ICESat2, now scheduled for Sep 15 at 5:46am PDT.Was the first rocket I ever watched launched in person, I look forward to seeing it off on its final mission.
