Built in the classroom.
Flown in orbit.
COSMOS Core is free, forever. Same engine the primes ship with.
From high school robotics labs to graduate COSMOS programs.
One console. Five stops. The same toolchain a student opens on a workbench is the toolchain flying their payload years later.
First contact.
High school robotics labs and intro engineering courses pick up COSMOS Core because it's free, open source, and works on the bench gear they already own.
From breadboard to bus.
Undergraduate aerospace, ECE, and capstone teams use COSMOS to command CubeSats, rovers, and ground stations — the same engine they'll see on the job.
Research-grade flight software.
Graduate labs script test campaigns, model failure modes, and prototype mission ops in Python and Ruby on the same toolchain that flies operational hardware.
Day one, same console.
Graduates land at satellite operators, launch providers, and defense primes — and find COSMOS already on the rack. Zero ramp-up on the tool. All ramp-up on the mission.
Flying real hardware.
The same skills, scripts, and screens follow them into the mission operations center. The console a student opened in a robotics lab is the console flying their payload today.
Three promises. No fine print.
The same engine the primes prototype with — open source, no signup, no key.
Modify, redistribute, and build your curriculum on COSMOS Core - for free.
From an Arduino on your desk to a CubeSat in LEO — same console, same code.

If it has a wire or a packet, COSMOS can talk to it.
A growing library, mostly written by the community.
Don't see your hardware? Write a plugin.
Any board. Any bus. Any protocol. The COSMOS Plugin SDK turns whatever you build into a first-class target — telemetry in, commands out, no fork required.
Built in the open. Improved by everyone who uses it.
