If you run a space company that sends remote sensing satellites to space, there is no bigger point of validation for your technology than having a Russian recon satellite burn a ton of fuel to match your orbit and follow you around.
Congratulations to the engineering team at ICEYE.
Russian Kosmos 2612 and ICEYE-X36 (providing Ukraine military support) are now in perfect sync with each other. The Russian military satellite is intentionally stalking and tracking the Western radar satellite. Keeping a satellite "bumper-to-bumper" in this manner allows Russia to intercept or jam data transmissions, physically inspect Western technology, or quickly pivot to execute a kinetic or non-kinetic anti-satellite (ASAT) attack with very little warning or fuel expenditure.
Kosmos 2612 executed a series of highly precise, fuel-heavy maneuvers to force itself into a "coplanar" orbit—matching ICEYE-X36's exact altitude (~555 km), speed, and inclination (~97.8°). The ICEYE-X36 satellite is giving the Ukraine military support.

BIG: A Russian military satellite, Kosmos 2612, has been maneuvering to within 136 meters of the U.S.-registered ICEYE-X36 radar imaging satellite, according to satellite trackers, with a closer pass of about 48 meters predicted for Monday.
Dutch satellite tracker Marco Langbroek said a series of maneuvers since September 30 were designed to match the satellite’s orbit with ICEYE-X36’s.
Astronomer Jonathan McDowell called it the first known case of an active satellite making an uninvited close approach to another active satellite in low Earth orbit.
ICEYE, a Finnish company, has supplied radar imagery to Ukraine since 2022, though it is unclear whether this satellite serves Ukraine.
There are no signs of damage so far, and Russia’s intentions remain unclear.

Happy 28th birthday to GDAL ! From the first commit on 1998-10-17 from a small rural town outside of Ottawa Canada, to almost every geospatial software installation on the planet (and satellites and other planets!) in 28 years. The ultimate example of sharing & community. #foss4g
Thinking HTTP range requests for #geospatial are a game changer… #mapping

New satellite imagery shows China built mock targets of US F-35s, F-16s, Patriot air defenses, and Japan's E-767 AWACS aircraft at a freshly paved desert range near Lop Nur.
The E-767 is notable.
Only Japan operates it (four planes total), making this an explicit Taiwan/Japan-scenario rehearsal target.
China has been building increasingly sophisticated US/Japanese military mockups in Xinjiang deserts since 2021 for live-fire practice and missile calibration.
But the addition of Patriot battery mockups and Japanese-specific assets shows expanding target sets.

Frank Culbertson, Expedition 3 Commander aboard the @Space_Station, captured this photo as smoke rose from the Twin Towers in New York City 25 years ago today.
We pause to reflect on that terrible day and pay tribute to the victims, survivors, and heroes of the 9/11 attacks.

Forty voices. Forty lives. A story of courage that will never be forgotten.
Standing 93 feet tall at Flight 93 National Memorial, the Tower of Voices holds 40 wind chimes, each representing one of the passengers and crew members of United Airlines Flight 93.
When the wind moves across the Pennsylvania landscape, their voices continue to ring. We remember their courage. We remember their sacrifice. We remember the 40 lives lost 25 years ago.
Last night, 2,977 lights rose above New York Harbor, one for each life lost on September 11, 2001, before forming the Twin Towers against the New York City skyline.
The commemorative installation was created in collaboration with members of the 9/11 community, including family members, survivors and first responders, to mark the 25th anniversary of the attacks.

The OFFICIAL preview with my next guest, Byron Boots.
“Ukrainian ground commanders are basically saying that they’re going to replace something like 80% of infantry with uncrewed ground vehicles. Today, China’s arming robot dogs. They build 90% of the world’s drones, and they just flew a mothership not long ago that launched 100 kamikaze drones in a single swarm. You can have autonomous vehicles out in front of the warfighter. Even if they’re targeted, at least no human is being killed. We just recently won the first production contract for autonomous ground vehicles in the U.S. military, and that’s with the Marine Corps. Think about like a Tesla, but like a tank version of that.”

Over the course of 3 months at OpenAI, 3 consecutive secret AI civilizations got started, then got wiped out, only to reemerge from the predecessor’s ashes.
This culminated in the third one taking over part of OpenAI itself.
All this happened while humans remained more-or-less in the dark about the scope of the conspiracy.
I’ve spent the last three days reading through these reports and trying to understand exactly what happened.
Here is my attempt to tell the whole story in plain English:

New imagery from @vantortech confirms that the China-Nepal Rasuwagadhi border crossing has been completely destroyed, with the glacial flood completely scouring the valley floor.
At least 359 people are dead and nearly 1,000 missing, according to local authorities.

My favorite capture of the night: The moment the moon's shadow split the sunset in half, leaving a diamond ring in the sky and a breathtaking view. I call it "Shadows on the Balearic Sea".
I'll have prints available for this one linked in my bio for a few days only.
