Spacetek’s CubeSat TOF on Board of CHESS Satellites

The EPFL Spacecraft Team has set itself the ambitious goal of launching a constellation of two satellites, called CHESS, in two years, which will help researchers gain a better understanding of the chemical composition of the outermost layers of our atmosphere, as well as of how it has changed over time.

To achieve this, the satellites will be equipped with several state-of-the-art instruments, including new TOF mass spectrometers developed and built by Spacetek Technology AG in collaboration with the University of Bern.
