@planetlabs has a series of great collects of China's Jiuquan Satellite Launch Center. Interestingly, the rotating service structure on pad 921 underwent modification in June likely to accommodate a larger payload fairing on the LM-2F rocket for the 4 September launch. Image
Here's a quick look at the service structure before modification. Image
Here's a nice off nadir shot during modification in June with a section of the structure removed. Image
And after modification... Image
The day of the launch with the LM-2F on the pad. Image
Lastly, a hazy shot later in the day prior to launch with the swing arms open. Image

Umbra synthetic aperture radar imagery acquired 0648Z 19APR2024 showed evidence of damage to the Iranian S-300PMU2 strategic surface-to-air missile battery in Isfahan since 15APR2024. A probable damaged 30N6E target engagement radar was visible in imagery still on the radar hardstand. Other battery system components however have been withdrawn from the site. Their status and location is currently unclear. According to senior U.S. military sources speaking to FOX News, “The Israelis hit what they intended to strike.”Image
In my haste to make the previous tweet I pulled callouts from other slides in the deck, so there were discrepancies that required amending. Apologies for deleting the tweet.

This is Luninets AB, located approximately 50 km north of the Ukrainian border in #Belarus. It's a reserve airfield that we often see used in air and air defense exercises. (Imagery: @planet) Image
Similarly, we also have Babryusk AB, another reserve airfield that #Russia has previously used in air defense exercises with Belarus. Like Luninets, we have an active EW site and a cleared runway. (Imagery: @planet) Image
Then there's Baranovichi where Russian Su-30SM likely stayed on. However, this low light image from December 2021 doesn't show the canards very clearly. (Imagery: @planet) BY Su-30SM parked in QRA right / prob RS Su-30SM on main ramp w/ prob BY MIG-29. Image

As #china claimed the Sakteng wildlife sanctuary in eastern #bhutan in June 2020—in likely an effort to sow further confusion—it built a new track to one of four new areas cleared for construction in the Dramana and Shakhatoe areas of western Bhutan. shorturl.at/gipNW
Given the Ladakh crisis that had just begun, it’s likely decision makers were off-balance as China exerted additional pressure with new deployments along the LAC, some of which we still see today. (imagery: @planet)
Furthermore, construction activity has also been monitored in the Langmarpo valley and further south on the Doklam plateau. Several areas have been cleared and we expect additional construction activity in 2022. Here's an area with new foundations (imagery: @capellaspace)
