Tianwen-1 (Orbiter)

Part of Zhurong

Tianwen-1 is China's first comprehensive interplanetary mission to Mars, consisting of an orbiter, a lander, and the Zhurong rover. Launched in July 2020, it reached Martian orbit in February 2021 and successfully delivered its payload to Utopia Planitia. The orbiter continues to gather advanced geological, atmospheric, and mineralogical data.

Hope (Al Amal)

The UAESA Hope probe revolutionized Martian meteorology through a high elliptical orbit that enabled continuous modeling of the global atmosphere across all local time zones. Its key achievements include discovering the sinuous discrete aurora, patchy proton aurora, confirming Deimos's planetary basaltic origin, and intercepting the interstellar comet 3I/ATLAS.

ExoMars Trace Gas Orbiter (TGO)

ExoMars Trace Gas Orbiter (TGO), launched in March 2016 by ESA and Roscosmos, is an orbital mission dedicated to studying the Martian atmosphere and searching for trace gases such as methane. Following a long aerobraking process, it began its scientific phase in April 2018 and remains operational, combining atmospheric research with its work as a communications relay.

Mars Reconnaissance Orbiter (MRO)

NASA's MRO mission, launched in 2005, has successfully operated for over 15 years. Using instruments like HiRISE and SHARAD, it has discovered vast subsurface ice deposits at mid-latitudes and serves as the primary communications relay for surface rovers.

Mars Express

Launched in 2003 aboard a Soyuz-Fregat, Mars Express is ESA's first planetary mission. The orbiter achieved a successful insertion and has operated for over two decades. It has revolutionized our understanding of Mars by confirming subsurface water ice, detecting methane, and mapping hydrated minerals that prove a habitable past.

2001 Mars Odyssey

The 2001 Mars Odyssey mission (NASA) is a Mars orbiter designed to map the elemental and mineralogical composition of the surface, search for water ice, and act as a communications relay. Launched in April 2001, it confirmed the presence of vast underground ice deposits and remains active after multiple extensions.
