  1. Ganymede Lander mission overview

  2. Purposes and main tasksof the space complex • Main destination of the space complex, composed of two spacecraft (orbiter andlander) is carrying out of researches of Jupiter and it’s natural satellite Ganymede. • The tasks of the orbiter: • entrance to the orbit with the specified parameters around Ganymede; • carrying out of distance researches of the satellite and it’s ambient space; • mapping of the Ganymede surface, selection of landing area for the lander; • transmission to the Earth of scientific data, images of the surface and telemetry data; • retranslation of the data from the lander. • The tasks of the lander: • entrance to the orbit with the specified parameters around Ganymede; • carrying out of soft landing to the surface of satellite in preliminary selected area; • carrying out of contact researches of the satellite; • transmission to the orbiter of scientific data, images of the surface and telemetry data (nominal channel); • transmission to the Earth of scientific data, images of the surface and telemetry data (redundant channel). Ganymede mission

  3. Initial data • Launch vehicles • separated launch of orbiter and lander with the LV of “Proton”/ “Angara” class; • upper stage– “Breeze-M”; • fairing with diameter of payload zone not less, than 3800 mm. • Mass budget • the initial mass of the spacecraft after separation from the upper stage – not less, than 4000 kg; • the mass of the orbiter on entrance to the orbit around Ganymede – not more, than 950 kg; • the mass of the lander after landing to the surface – not more, than 800 kg. • Ganymede characteristics • distance to Earth~ 640 mil. km; • FFA – 0,146g; • orbital velocity – 10,880 km/s; • temperature on the surface – 70…152 K; • surface – ice crust up to 950 km; • atmosphere – none. Power budget The summary electrical power, provided for all systems of orbiter and lander – not less, than 70 W. Ganymede expedition
