SpaceX opens orbital safety data to all operators with free SSA service

In a move that could significantly reshape how satellites are managed in increasingly crowded orbits, SpaceX has begun providing precise positional awareness of objects in Earth orbit to satellite operators worldwide—free of charge.

The announcement was confirmed by Elon Musk as he shared this on his X (formerly known as Twitter)

“SpaceX is now providing precise positional awareness of objects in Earth orbit to all satellite operators for free,” Musk said.

“This will greatly reduce the probability of collisions that create orbital debris (space junk) hazards,” Musk added.

The initiative is powered by a new Space Situational Awareness (SSA) system called Stargaze, developed by SpaceX and rolled out through Starlink.

According to Starlink, the system enables ephemeris sharing and conjunction screening—two critical processes used to predict and prevent potential satellite collisions.

Starlink said the service is designed to “maximize safety for all satellites in space,” adding that SpaceX “will be making Stargaze conjunction data available to all operators, free of charge.” 

The company explained that by offering ephemeris sharing and conjunction screening at no cost, it hopes to “motivate operators to take similar steps towards ephemeris sharing and safe flight.”

As Earth’s orbit continues to grow more crowded with active satellites and debris, collision avoidance has become an increasingly important operational issue for both commercial and government space operators. 

Even low-energy impacts can generate additional debris, compounding long-term risks to spacecraft, missions, and orbital infrastructure.

In this context, SpaceX has introduced Stargaze, a space situational awareness capability intended to improve the detection and tracking of objects in orbit using data derived from its satellite systems. 

The availability of higher-quality conjunction data may support more informed collision-avoidance decisions among satellite operators, particularly as overall traffic in low Earth orbit increases.

As launch activity accelerates and orbital environments become more complex, maintaining accurate tracking and reducing debris-creating events are increasingly recognized as essential components of safe and sustainable space operations.
