Parts Provided For NASA’s Artemis Lunar Program

Estonian company Crystalspace, partnered with Tartu Observatory of Tartu University and Krakul, has been selected by Maxar Technologies, a partner and innovator in Earth Intelligence and Space Infrastructure, to build two cameras that will act as a stereo pair to monitor the operations of a robotic arm that will collect regolith samples from the Moon.

The Crystalspace cameras will be part of Maxar’s robotic arm called Sample Acquisition, Morphology Filtering, and Probing of Lunar Regolith (SAMPLR). Maxar’s SAMPLR robotic arm will be the first United States-provided robotic arm operated on the surface of Earth’s Moon since the Surveyor missions more than 50 years ago.

SAMPLR is one of 12 externally-developed payloads that NASA selected in 2019 as part of the Commercial Lunar Payload Services (CLPS) project, which allows rapid acquisition of lunar delivery services for payloads like SAMPLR that advance capabilities for science, exploration or commercial development of the Moon.

The two cameras built for the lunar mission will need to withstand extreme conditions. Jaan Viru, founder of Crystalspace: “During take-off and the entire mission, the cameras will be subjected to extreme conditions and temperatures from -173 to +100 degrees Celsius that occur on the Moon. We are proud to provide our profound knowledge and experience with satellite camera systems to Maxar’s SAMPLR arm.”

Estonia became a space nation with a human-made object in space when the nanosatellite ESTCube-1 reached orbit in 2013. “Most of our current project team were among the core developers of the ESTCube-1 Cubesat mission and we have developed payloads for multiple satellites that are orbiting the Earth. We are now most excited to combine our years of experience with space cameras to deliver a stereo camera system that will enable the exploration of the Earth’s Moon,” explained Viru.

Crystalspace will develop the camera solution together with Tartu Observatory of the University of Tartu and Estonia’s leading IoT and autonomous systems development company Krakul. Crystalspace will deliver system integration and the design and optics of the camera in cooperation with Tartu Observatory. The cameras will be tested in the laboratories at the Tartu Observatory. Krakul will design the electronics and embedded software for the stereo cameras.

According to Dr. Mihkel Pajusalu, Associate Professor of Space Technology and Head of the Space Technology Department of the Tartu Observatory, this is a big step in the development of Estonian space technology. “Together with other recent Estonian advances in space, it shows that Estonia has become a recognized space country and proves the importance of both space technology and technology education in Estonia in general,” said Pajusalu.

In addition to this mission, the Tartu Observatory also participates in the European Space Agency’s F-class science mission Comet Interceptor, due to launch in 2028, with its OPIC instrument (Optical Periscopic Imager for Comets). The observatory has also participated and is currently participating in several other ESA missions with non-instrument contributions, like the Ariel exoplanet mission just adopted by the European Space Agency.

Jaan Hendrik Murumets, CEO of Krakul, added: “Sending one’s development to the Moon is every engineer’s dream. Krakul’s solutions can be found on Earth, in space and the depths of the seas, and now also on the surface of the Moon.”

For the production of the two cameras, Crystalspace has partnered with Incap Electronics Estonia to produce the electronics, Insero to design the mechanics, Radius Machining to produce the mechanics and Tauria for software development. The flight models will be completed in the first half of 2021.
