CHESS is a real space mission coordinated by the EPFL Spacecraft Team. Join the team to take your first step into space! click the button bellow for recruitment session zoom link
A Swiss orbital mission
CHESS is a Swiss space mission to monitor the Earth’s upper atmosphere using two nano-satellites.
CHESS is a Swiss space mission to monitor the Earth’s upper atmosphere with 2 mass spectrometers aboard 2 nano-satellites. Made at Bern University, it’s a world class gas analyser, and an outstanding piece of technology.
The adventure has already started !
Team creation and first mission designs
In-depth cost study and payload requirements
First design for all the subsystems
Partial redesign of the platform and preparation for PDR
Flatsat developement, testing ,and preparation for CDR.
System integration and testing
The big boom
Getting all the data from the sat, updating, first data analysis
We will continue gathering data until reentry.
Nation wide project

CHESS is a student project, supervised by well-known teachers and universities.
Main payload
Universität Bern is famous around the world for its cutting-edge mass spectrometers. Each CHESS satellites will receive one CubeSat TOF, a miniaturized version of the regular mass spectrometers.
Second payload
Analyzing the atmosphere is possible with the CubeSat TOF, but to be accurate in the measurements, we need a very precise positioning system: a GNSS made by the ETH team.
Flight Software
One of the critical elements in a satellite is the flight software. HE-ARC brings its long experience in embedded software development into the CHESS mission.
On Board Computer
HES-SO students and teachers work on solutions for the satellites' brain, a state-of-the-art nano computer interfacing all the other subsystems.
Ground Station
It's cool to send a satellite into space, but it's better to get all the data back on earth! HSLU takeover this strategic part of the project, using its experience with SwissCube, the first swiss satellite in history.
Coordination + Satellite
The EPFL team coordinate the administrative and financial part. Also, all the other subsystems (electric power, structure...) will be located design and build at the EPFL.
