100 Messages to Planet Earth
After looking back to the history during this World Space Week, now we're reaching the future. We launch an initiative to collect 100 Messages to Planet Earth and send selected messages aboard WISA Woodsat to space. How your message can get aboard – read below!

World Space Week from October 4 to 10 is an official United Nations theme week that is celebrated in over 95 nations. The week has its origins in the commemoration of the launch of Sputnik 1 on 4 October 1957, kicking off the space age, but today the week has a broader significance as an international celebration of science and technology, and their contribution to the betterment of the human condition.

“WISA Woodsat™ is an interesting material science mission, and a satellite made of renewable raw material is a message. The resources of our planet are finite. We need to adapt our lifestyle to the resources and use renewable, recyclable, and reusable materials,” says Ari Voutilainen, WISA Woodsat project manager for UPM Plywood.

Now you have a unique opportunity to send your own Message to Planet Earth by launching it to space with WISA Woodsat™. Propose your Message to Planet Earth by sending a direct message (DM) to @wisawoodsat either on Twitter or Instagram by November 6, 2021.

Our team will select a set of 100 messages, that will travel to space with WISA Woodsat. We will publish the selected messages on the WISA Woodsat homepage,, and other media.

“Adding the Messages to Planet Earth to satellite’s payload is not only a pleasure but also another effort to popularize space technology and its benefits. From space you have a unique perspective of our blue planet and our responsibility to take good care of it,” says WISA Woodsat mission manager Jari Mäkinen of Arctic Astronautics.
