‘Whatever Russia is testing, it’s sophisticated’: 2 Russian satellites get within 10 feet of each other in orbit

Two Russian spacecraft just demonstrated a very particular set of orbital skills.

The satellites, known as COSMOS 2581 and COSMOS 2583, got within just 10 feet (3 meters) or so of each other on April 28, according to COMSPOC, a Pennsylvania-based space situational awareness company.

"This wasn’t a coincidental pass — COSMOS 2583 performed several fine maneuvers to maintain this tight configuration," COMSPOC wrote in a May 1 X post, which featured an animation of the rendezvous.

The two satellites and a third one, COSMOS 2582, launched to low Earth orbit in February 2025 atop a Soyuz rocket. According to COMSPOC, all three of them were involved in the recent rendezvous and proximity operations (RPO), as was "Object F," a subsatellite previously deployed by COSMOS 2583.

During the 10-foot close approach, "COSMOS 2582 trailed the formation at sub-100 km range, while Object F passed within 15 km of 2582 and within 10 km of 2581 — neither maneuvered," wrote COMPSOC, which analyzed radar tracking data gathered by the California company LeoLabs.

"For context: in late 2025 to now, we tracked these same COSMOS satellites performing 3-object RPO," COMSPOC added in the May 1 X post. "Whatever Russia is testing, it’s sophisticated."

Such sophisticated orbital maneuvering is not exactly surprising; we’ve seen similar things from Russia before. For example, according to outside observers, the nation has operated multiple "inspector satellites," including COSMOS 2542, which made a close approach to a U.S. spy satellite in 2020.

The other major space powers have such capabilities as well. American and Chinese satellites have also been observed checking out other nations’ spacecraft high above Earth.

Brembo Brings Fluid-Free Brakes to Production Cars

https://www.autoblog.com/news/brembo-brings-fluid-free-brakes-to-production-cars

Relying on Hydraulic Brake Systems Since Time Immemorial

Braking systems have stuck to the same playbook for a very long time. Step on the pedal, hydraulic fluid travels through lines, pressure builds, and the calipers bite down on the rotors. It doesn’t matter if you’re driving a city hatchback, a big SUV, or a supercar – the basics haven’t really changed.

Braking tech has definitely moved forward – drums gave way to discs, ABS and brake force distribution arrived, and now we have regenerative braking and stability systems. But underneath all that, cars still depend on hydraulics to actually bring things to a halt.

That could finally be changing. Brembo just confirmed that its Sensify intelligent braking system is now in large-scale production. It’s one of the strongest signals yet that fully by-wire brakes are about to go mainstream.


A Brake System Without Hydraulic Fluid

Brembo says Sensify uses a fluid-free setup, ditching the usual hydraulic circuits and central actuators. Instead, each wheel gets its own electronic brain, so braking force is managed by software, not just hardware.

Put simply, pressing the brake pedal doesn’t push fluid through lines anymore. Instead, your input is read electronically and each wheel gets its own dose of braking force.

That means much finer control. Brembo claims the system can constantly adjust braking force based on road conditions, how the car is moving, and how much grip you have.

Brembo also sees Sensify as a big step toward software-defined cars. New EVs and next-gen vehicles are built around central software, where updates and even driving feel can change with a download. Sensify fits right in, especially for advanced driver aids and future self-driving tech.

Interestingly, Brembo said that Sensify will be standard on every car in this unnamed production run. So this isn’t just a one-off supercar experiment – we’re talking real volume, with contracts for hundreds of thousands of units each year already in place.

So Which Automaker Is Using It?

That’s the big question. Brembo just calls the customer a “leading global vehicle manufacturer” and won’t say which one. Some brands have played with steer-by-wire and brake-by-wire in concept cars, especially among premium EVs. But rolling out a fully fluid-free brake system in mass production is a much bigger leap, especially since brakes are so crucial for safety and driver trust.

This could be one of those changes that quietly reshapes the industry over the next decade. Most drivers won’t notice if their car uses hydraulics or electronics to stop – just like nobody thinks about throttle cables or old-school handbrakes anymore. But underneath, it’s another step toward cars becoming software-driven machines instead of purely mechanical ones.

If Sensify really works as smoothly as Brembo says, old-school hydraulic brakes might soon start to feel outdated.
