The EPFL Spacecraft Team is a student association at EPFL developing the CHESS mission, which aims to deploy two 3U CubeSats to study the composition of the exosphere, the outermost layer of the atmosphere.
The team has already completed two in-orbit demonstrations of its on-board computer in 2023 and 2025. Its next milestone is the launch of its first operational satellite, CHESS Pathfinder 0, planned for 2027. The satellite will carry two payloads, including a multi-GNSS receiver developed by ETH Zurich and a SPAD-based flight camera by NovoViz.
The team brings together more than 80 members, organized into specialized groups covering all aspects of the mission, from satellite subsystems to system engineering and ground operations.
