The European Space Agency‘s experimental satellite Artemis has successfully transmitted data from the Japanese earth observation satellite Adeos II, ESA announced Monday. ESA and Japan’s National Space Development Agency (NASDA) had earlier agreed to cooperate on a data relay service between ESA’s Artemis geostationary spacecraft and NASDA’s Adeos II in low earth orbit, using ESA’s ground station in Redu, Belgium.

In this framework, ESA and NASDA performed a series of tests in late March to demonstrate the system’s performance and the operational links between the Adeos II team in Tsukuba, Japan, and the Artemis Mission Control Facility in Redu.
