Tianwen-4

The name "Tianwen-4" refers to a proposed future Chinese planetary exploration mission, likely targeted at a destination beyond Mars. As of late 2024, details surrounding Tianwen-4 are still largely preliminary and subject to change. The mission is expected to build upon the successes of the Tianwen-1 mission, which successfully landed a rover on Mars.

While specific details are scarce, Tianwen-4 is broadly anticipated to be a multi-faceted mission potentially involving an orbiter, lander, and possibly a sample return component. Several destinations have been speculated, including:

• Jupiter System: Exploring Jupiter and its moons, particularly Europa, which is considered a potential location for extraterrestrial life due to its subsurface ocean.
• Uranus/Neptune System: Conducting the first in-depth exploration of the ice giants and their complex systems of moons and rings.
• Venus: Further investigation of Venus, potentially involving advanced atmospheric probes or durable landers capable of withstanding the planet's harsh conditions for extended periods.

The mission is expected to incorporate advanced technologies in areas such as autonomous navigation, deep-space communication, and potentially new propulsion systems. The official launch date and final mission objectives are still to be formally announced by the China National Space Administration (CNSA).
