The goals of the planned Tianwen-4 Jupiter mission include: study of the interaction between magnetic fields and plasma present in the Jovian system, examination of the compositional variations in the Jovian atmosphere, exploration of the internal structures and surface characteristics of either Ganymede or Callisto, as well as investigation of the space environment surrounding the ...

This is a list of named craters on Callisto, one of the many moons of Jupiter, the most heavily cratered natural satellite in the Solar System (for other features, see list of geological features on Callisto). [1]
Textured terrain in Callisto's Asgard basin. Asgard is the second largest multi-ringed basin (large impact crater) on Jupiter's moon Callisto. [2] It is named after Asgard, the realm of the gods in Norse mythology. The central part of Asgard is dominated by the domed Doh impact crater.
Valhalla is the largest multi-ring basin on Callisto and in the Solar System (with diameter up to 3,800 km). [4] It was discovered by the Voyager probes in 1979–80 and is located on the leading hemisphere of Callisto, in its Jupiter facing quadrant slightly to the north of the equator (at about 18°N latitude and 57°W longitude).
The future of moon exploration. Meanwhile, Chandrayaan-3, which includes a lander, rover and propulsion module, lifted off on July 14 and entered lunar orbit last weekend.
The largest, Ganymede, is the largest moon in the Solar System and surpasses the planet Mercury in size (though not mass). Callisto is only slightly smaller than Mercury in size; the smaller ones, Io and Europa, are about the size of the Moon. The three inner moons — Io, Europa, and Ganymede — are in a 4:2:1 orbital resonance with each other.
