SpaceX opens the door to "sharing" its spacecraft tracking data with its "StarGaze" Space Situational Awareness (SSA) system.

Stargaze aggregates data from ~ 30,000 star trackers distributed across the StarLink satellite fleet to generate accurate orbit estimates and predictions of position and velocity for all detected objects in near real-time and the system generates Conjunction Data Messages (CDMs). 

SpaceX will make Stargaze conjunction data available to any satellite operator (free of charge) that submits its own ephemeris (trajectory) data to the platform. Stargaze ephemeris is updated and shared publicly every hour.

BIG question: How long will Stargaze be "free of charge" ??? https://news.satnews.com/2026/02/18/spacex-unveils-stargaze-system-to-revolutionize-space-traffic-management/

Orbital House of Cards – CRASH Clock Metric

Researchers have updated the possibility that satellites in low earth orbit (LEO) could collapse after accidental collisions quickly cascade into a vicious cycle where initial collisions create a huge vortex of dangerous space debris, which creates even more collisions, and then even more collisions – just like a massive vehicle pileup on an ice covered interstate highway…this cascading collision scenario is known as the Kessler syndrome.

The researchers propose a new metric, the CRASH Clock, that measures the timescale for a possible Kessler like scenario to occur after a severe loss of space situational awareness. They propose the CRASH Clock is currently 5.5 days, which is the window of opportunity to recover/stop a wide spread cascading collision event. https://futurism.com/space/earths-lower-orbit-rapidly-collapse

Can you say “Deconfliction”? The Risk of Satellite Collisions is going Parabolic – Not a good thing.

The latest TechAptitude post is is live - reviews the current state of Space Situational Awareness (SSA) and the growing risk of spacecraft collisions.
