![]() One possible Earth-Jupiter mission trajectory and timeline was presented at the 2020 General Assembly meetings of the EGU. As of early 2021, the aforementioned 'JCO' and 'JSO' mission profiles are competing to be realized as the Gan De Jupiter system mission. In 2018, Pei Zhaoyu, the deputy director of CNSA's Lunar Exploration and Space Program Center stated that China was planning to conduct four major interplanetary missions before the end of the 2020s the four missions include a mission to Mars ( Tianwen-1), a main-belt comet and asteroid sample-return mission ( ZhengHe), a Mars sample-return mission, and a Jupiter system mission. In the hope of building upon these achievements, CNSA began to contemplate more ambitious interplanetary missions in the 2020s and beyond. On October 15, 2003, CNSA launched China's first independent crewed orbital mission subsequently it prosecuted successful robotic lunar orbital missions ( Chang'e 1 and Chang'e 2) and a robotic lunar lander/rover mission ( Chang'e 3). The tentative name of this mission references the fourth century BCE Chinese astronomer ' Gan De' who made early planetary observations and reputedly first observed the Galilean moons with the unaided eye. Finally, presentations by Chinese researchers suggest that the Gan De Jupiter mission may include an additional probe that would conduct a fly-by of Uranus sometime after 2040. In contrast, the 'JSO' mission profile, while broadly similar to that of 'JCO', would forgo an attempt by a spacecraft to orbit Callisto and instead would focus on more intensive studies of the Galilean moon Io (the 'JSO' mission profile also does not appear to include a lander though it may involve sending the spacecraft to the Sun-Jupiter L1 point at the conclusion of its tour of the Jovian system). 'JCO' would involve a spacecraft conducting fly-bys of Jupiter's irregular satellites before it enters into a polar orbit about Callisto this mission profile also may include a Callisto lander. Īccording to reports in the Western media, there are two competing mission profiles as of January 2021: the 'Jupiter Callisto Orbiter' (JCO) and the 'Jupiter System Observer' (JSO). The goals of the planned Gan De Jupiter mission were detailed in an article published in a Chinese academic journal, they include the following: 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 aforementioned Galilean satellites. 5.4 Radio + optical link + radio science package. ![]() 5.3 Geology/glaciology/geochemistry analyzers package.5.2 Multi-wavelength imaging/spectroscopy package.
