On Thursday, more satellite imagery of Chuhuiv Air Base was captured by a space company, revealing further damage to fuel storage areas and other airport infrastructure.

In the Brestsky training area near Brest, Belarus, Maxar imagery revealed the presence of military forces and over 50 heavy equipment transporters.

Near Sergievka, Russia, Maxar imagery detected a military convoy heading west toward Ukraine, approximately six miles east of the Ukrainian border.

Earlier on Thursday, limited satellite imagery was available due to cloud cover, which hindered the ability to observe Russian invasion attacks and troop movements from space, particularly in the southern part of Ukraine.
