Artemis, the Advanced Data-Relay and Technology Mission Satellite, is the latest and most sophisticated telecomunications satellite to be developed by the European Space Agency. Artemis is equipped with sophisticated radio systems and for the first time will use lasers to transmit data directly between satellites.
This animation is divided into four sequences:
-SEQUENCE 1: the H2 launch of the Artemis spacecraft from the Tanegashima launch site in Japan, as seen from an altitude of 1500km, introduction to a geostationary transfer orbit, and the circularisation of the orbit by booster firing. Launcher is seen passing South of Hawaii, maintaining constant speed and altitude before separation occurs.The satellite rises over South America, continuing south of the Equator towards the Indian Ocean. The elliptical orbit, with an eight hour period, becomes visible above the North Pole; the apogee booster motor is fired to give an orbital period identical to that of the Earth.
-SEQUENCE 2: the principle of data-relay
