Georges Lemaître ATV

The Georges Lemaître ATV, or Automated Transfer Vehicle 5 (ATV-5), was a European uncrewed cargo spacecraft, named after the Belgian astronomer Georges Lemaître.[3] The spacecraft was launched during the night of 29 July 2014 (23:44 GMT, 20:44 local time, 30 July 01:44 CEST),[4] on a mission to supply the International Space Station (ISS) with propellant, water, air, and dry cargo. It was the fifth and final ATV to be built and launched. Georges Lemaître was constructed in Turin, Italy, and Bremen, Germany. Cargo loading was completed in Guiana Space Center on 23 July 2014.[5]

Georges Lemaître was launched on an Ariane 5ES rocket from the Guiana Space Centre in Kourou, French Guiana. The launch was conducted by Arianespace on behalf of the European Space Agency.

Artist Katie Paterson sent artwork to the International Space Station aboard ATV-5.[6][7][8]

Mission payload

Georges Lemaître ferried 6.6 tonnes of experiments, spare parts, clothing, food, fuel, air, oxygen and water to the ISS.[5] Included was a Haptics-1 joystick which will be the first force reflecting joystick to be used in space. The Haptics-1 joystick communicates in real-time with a space qualified tablet PC (Dell Latitude 10) to allow astronauts to perform a range of seven physiology experiments.[9]

In addition to the usual cargo ATV-5 performed 2 experiments:

LIRIS (Laser InfraRed Imaging Sensors) was a new autonomous rendezvous sensor set that allowed future ships to dock with uncooperative targets, like debris or sample capsules - Georges Lemaître used a demonstration version of it instead of standard optical sensors bouncing light off the reflectors around ISS docking port.[10]

Break-Up Camera recorded ATV in infrared as it broke up performing atmospheric reentry above Pacific Ocean. After recording was completed, a reinforced SatCom capsule doubling as a black box began transmitting data to one of the Iridium satellites through the gap in plasma behind the vehicle. A message was sent with information on the number of pictures taken — nearly 6000 — as well as accelerometer and magnetometer readings, details of the sphere rotation, and a temperature reading. After that first message, no further data was transmitted.[11]
