Check out this awesome item from @MemorySteelUA. It's a stylish piece of a Russian T-72 tank No 583 destroyed during The Battle for Kyiv in early 2022. What a cool way to support a Ukrainian company.

In terms of classification level of emergencies at Dept. of Energy facilities, a 'Site Area Emergency' sits underneath a 'General Emergency' and above 'Unusual Event' or 'Alert'.
The DoE defines a Site Area Emergency as "Events are in progress or have occurred which have caused (or likely will cause) major failures of plant functions that protect the public, or involve security events with intentional damage or malicious acts that could lead to the likely failure of (or prevent effective access to) equipment needed to protect the public."
There are no outward indications that the incident is any more than what officials have reported, however it is still a significant incident.
Per a post on Facebook from the SRS, there was a fire at the Savannah River National Lab, within the Savannah River Site, earlier this evening resulting in the declaration of a Site Area Emergency at 5:39pm local time. The fire was extinguished and no contamination is reported outside the affected facility. All entrances to the SRS have been secured and air traffic in the vicinity is being restricted.
The Savannah River National Lab is the research portion of the site and conducts a variety of radioactive related research.

Leaked fragments of the document cementing the local humanitarian ceasefire beteeen Russian and Ukrainian forces around Russia-occupied town of Oleshky in Ukraine's Kherson Oblast.
Acccording to the agreement, Ukrainian citizens who expressed a desire to return to non-occupied parts of Ukraine were set to be evacuated to the Anapa Airport in southern Russia, and then transported to Homel in southern Belarus on a Russian military transport plane.
U.S. First Lady Melania Trump says that the geographical area of the humanitarian ceasefire between Russia and Ukraine has expanded beyond Russia-occupied town of Oleshky, within Ukraine's Kherson Oblast, to provide safe passage for the humanitarian convoys.
The limited truce is set to last from October 27, 2026, 01:00am UTC, until November 1, 2026, 8:59pm UTC.
For reference, this is about like dissipating the heat from a campfire or a rack of 32 H100s
F-35 electronics put out about 30 kW of waste heat, and Block 4 is expected to push that to 47 kW. The jet’s engine was optimized for about 14 kW. The U.S. Navy just gave Lockheed more money to work on the fix.

🛰️ CHANGING OF THE KINGS: China's TJS-17 & TJS-19 swap coverage in GEO
The "Four Kings" (TJS-15, 16, 17, and 19) are classified as Chinese GEO Satellites launched in 2025 to support the PLA's SIGINT and early warning missions.
Over the past month, our team watched two of the "Four Kings" satellites trade places across 40° of the GEO belt, leaving one sitting between Yaogan 41, a GEO surveillance satellite, and a U.S. inspector, USA 270.
TJS-17 (SSC.63524), the "King of the North", held 164.5°E (above the Pacific, just west of Nauru) since Aug 2025. On 29 Sep it raised its orbit ~202 km and began drifting west at ~2.6°/day.
TJS-19 (SSC.63924), the "King of the South", held 141.3°E (above the equator north of New Guinea) since May 2025. On 7 Oct it lowered its orbit ~197 km and began drifting east at ~2.5°/day, toward the slot TJS-17 had just left. The two crossed paths on 8-9 Oct.
TJS-17 stopped its drift on 15 Oct and parked at ~123.5°E, between YAOGAN-41 (SSC.58582) at 123.2°E and GSSAP USA 270 (SSC.41744) at 125.3°E. Its new spot sits above the Molucca Sea, nearly due south of the Philippines and Taiwan.
TJS-19 reached 167.3°E and then burned again on 22 Oct to drift back west at ~0.85°/day. That's an interesting use of fuel, possibly a correction for an overshoot.
Net effect: Western-Pacific coverage at 165°E stays (TJS-19 takes over), 141°E is now empty, and TJS-17 now watches the South China Sea / Taiwan Strait from ~123°E.
A coordinated handoff or a new mission? We'll keep watching.

Incredible footage of two Russian Kalibr cruise missiles being intercepted simultaneously by a single MIM-23 HAWK air defense missile.

More footage from Lipetsk. We can see a "Pantsir" anti-aircraft gun-missile system actively engaging aerial targets.
There is no characteristic explosion following a hit on an aerial target. It’s possible the Pantsir failed to do the job. 😏

Pakistan announced nuclear explosions at two sites in 1998: five at Ras Koh on May 28, then another in the Kharan Desert on May 30. @CoreyAH identified where the Kharan shot likely happened. I processed 1998 SPOT & LANDSAT imagery and ... she's right! Clear ground disturbance.
