Europe's ATV Johannes Kepler supply ship on its way to Space Station
ESA's second Automated Transfer Vehicle, Johannes Kepler, has been launched into its targeted low orbit by an Ariane 5. The unmanned supply ship is planned to deliver critical supplies and reboost the International Space Station during its almost four-month mission. Read more
When ATV Johannes Kepler is lofted into space on 15 February, an ESA tracking station on Portugal's Santa Maria island will watch closely, gathering crucial data as Ariane 5 streaks overhead. In 2008, the Santa Maria station, located five kilometres from the town of Vila do Porto on the Portuguese island of Santa Maria, in the Azores, became the latest station to join ESA's global ESTRACK tracking network. Santa Maria's 5.5 m-diameter antenna provides crucial tracking services for Ariane 5 rockets as they boost Europe's Automated Transfer Vehicles (ATVs) into orbit. Read more
After Ariane 5 lofts ATV Johannes Kepler into space on 15 February, ESA's Artemis data relay satellite will be ready for action. Artemis will provide communications between Johannes Kepler and the ATV Control Centre (ATV-CC) in Toulouse, France. Hovering some 36 000 km above the equator at 21.4šE, Artemis will route telemetry and commands to and from the control centre whenever the satellite sees the International Space Station or ATV. During every ATV-2 orbit, there is close to 40 minutes of continuous contact. Read more
