100 Messages to Planet Earth

WISA Woodsat™ celebrates UN’s World Space Week by launching an initiative to collect 100 Messages to Planet Earth and by taking selected messages onboard WISA Woodsat for a space ride. 

World Space Week is an international celebration of science and technology, and their contribution to the betterment of the human condition.

We are using the “100 Messages to Planet Earth” initiative to provide you a unique opportunity to propose your own Message to Planet Earth and by launching it to space with WISA Woodsat™.

How to suggest your own message

  • Propose your Message to Planet Earth by sending a direct message (DM) to @wisawoodsat either in Twitter or Instagram by November 6, 2021.
  • Be brief (less than 500 characters), positive and polite.

WISA WOODSAT on social media


Our goal is to put the world’s first wooden satellite on Earth’s orbit during the first half of 2022.

WISA WOODSAT is a nanosatellite based on the popular CubeSat standard. The satellite measures roughly 10 x 10 x 10 cm, which is equivalent of 1U CubeSat.

The satellite is designed and built in Finland and it will be launched to space during the first half of 2022 with a Rocket Lab Electron rocket from the Mahia Peninsula launch complex in New Zealand.

The mission of the satellite is to test the applicability of wooden materials, especially WISA-Birch plywood in spacecraft structures and expose it to extreme space conditions, such as heat, cold, vacuum and radiation, for an extended period of time.
