Invitation to the unveiling of WISA Woodsat prototype

Press Release 5.5.2021 14:30 EEST

UPM Plywood, Arctic Astronautics and Huld will present the prototype of the first ever wooden satellite WISA WOODSATTM on 12 May on UPM Plywood’s YouTube channel. The live event begins at 12 EEST (11 CEST) and is open for all interested.

The event will be hosted by Ari Voutilainen from UPM Plywood and features Sami Uuksulainen from UPM Plywood, Jari Mäkinen from Arctic Astronautics and Kevin Vainio from Huld. The presenters will unveil the prototype, explain the technical aspects of the satellite in detail and discuss the challenges of this unique space mission. They will also answer questions sent via channel's chat or social media.

The project for launching this first ever wooden satellite was revealed to the world in April and was welcomed with great enthusiasm. WISA Woodsat will be launched into Earth’s orbit by the end of 2021 from the Mahia Peninsula launch complex in New Zealand. The satellite will be carried to polar orbit by Rocket Lab’s Electron launch vehicle.

The nanosatellite is designed and built in collaboration with Arctic Astronautics, Huld and UPM Plywood. It will gather data on the behavior and durability of plywood over an extended period in the harsh orbital conditions in order to assess the use of wood materials in space structures. The specially coated WISA®-Birch plywood will be monitored by a suite of sensors provided by the European Space Agency and two cameras. One of the cameras will be on deployable boom.

In addition to testing plywood, the satellite will demonstrate accessible radio amateur satellite communication, host several secondary technology experiments, validate theKitsat satellite platform in orbit, and popularize space technology to the public.

The countdown to WISA Woodsat’s launch can be followed on the mission website WISA Woodsat can be found in social media channels with the handle @wisawoodsat and #wisawoodsat.

The media can see the satellite and interview the key persons at UPM headquarters in Helsinki on 12 May after the online event. Because of the COVID restrictions, the time slots are shared individually; please contact UPM media team at or +358 40 588 3284 in advance.

Arctic Astronautics
Arctic Astronautics is a start-up from Finland, which has created the Kitsat educational satellite and the related STEM teaching material package. Kitsat is a fully functional one-unit CubeSat, specifically made for educational use with earthly components. It can be also used for stratospheric flights or easily upgraded with space-qualified parts into a qualified satellite, as demonstrated with WISA®Woodsat. Arctic Astronautics graduated from the European Space Agency's Business Incubation Center in Finland in 2020. –

Huld is a European technology design house with experience from the space industry since 1989. It is now also reaching out to the New Space industry combining software and testing knowhow with tailor-made additive manufacturing mechanisms and out-of-the-box thinking. Huld provides the additively manufactured deployable camera boom and related structures for the mission. –
