WISA Woodsat was tested at ESTEC

Press Release 9.7.2021 15:00 EEST

WISA Woodsat satellite was put through rigorous tests during this week at ESTEC, the technical centre of the European Space Agency located in the Netherlands. The world’s first wooden satellite is now certified for a rocket ride and the final pre-launch phase can begin.

The model used for the tests was an exact copy of the actual satellite to be launched to space. The satellite was subjected to a rigorous vibration test, mimicking a ride to space atop of a rocket shaken by the engines. The satellite also faces hard acoustic noise from the engines accentuated by aerodynamic forces around the fairing.

According to WISA Woodsat mission manager Jari Mäkinen, the structure and the plywood panels of the satellite resisted the forces well, as expected, and can endure the spaceflight from the vibration point of view. Only a minor mechanical problem occurred as two screws of the deployable camera boom loosened during the forceful shaking.

“These tests are done precisely for finding hiding problems. Everything must be tested to a tee because design faults can’t be repaired after launch. The detected fault will be analyzed and fixed promptly as the deployable camera used to monitor the satellite is a vital feature”, says Mäkinen.

The WISA Woodsat team consists of members from UPM Plywood, Arctic Astronautics, Huld and European Space Agency. The latter provides a sensor package for analysing the behaviour of the plywood panels.

The world’s first wooden satellite, WISA Woodsat, is scheduled to be launched to orbit by the end of 2021 from the Mahia Peninsula launch complex in New Zealand. WISA Woodsat’s space journey can be followed online and on social media channels.

About WISA Woodsat
WISA Woodsat is the world’s first satellite using wood in its primary structure. It is made of WISA-Birch plywood, which is coated against strong UV radiation using a new atomic layer deposition method. The comparison panels are coated with industrial UV lacquer. WISA Woodsat will be launched to space from New Zealand using Rocket Lab’s Electron rocket. The mission is exploring the behavior of plywood in space for a period of two years. The countdown to WISA Woodsat’s launch can be followed on the mission website wisawoodsat.space and in social media channels with the handles @wisawoodsat and #wisawoodsat.
