How many Mars missions are there?  

China has successfully launched its first interplanetary mission Tianwen-1 to Mars on 23 July, get all the details about the How many Mars missions are there?  and how many Mars Missions are operational right now.

The exploration of Mars Planet by humans is not new. While maneuvered missions have remained financial and logistical near-impossibilities, unmanned missions started in 1960. Mars has historically been unneighborly to Earth’s attempts to visit it. Mars is also called the Red Planet. Many missions have attempted to Mars in search of life and other things, but half of the attempts have failed, But since 1996, Mars exploration has undergone a revival with data from four orbiters and four landed missions evolving a new view of Mars as an Earth-like world with a complex geologic history.There have been 56 Mars missions so far, out of which 26 have successful. Recently China has successfully launched its first interplanetary mission Tianwen-1 to Mars on 23 July, the spacecraft will reach Mars in February 2021. when the spacecraft reaches Mars China could become just the second country to land and possess a rover on the Martian surface. This Mission has three Spacecrafts, These Spacecraft will work to study the geology of Mars and learn more about what might be hiding underneath the planet’s surface.

currently operational missions on Mars are one lander (InSight) and one rover (Curiosity) with another rover (Perseverance) due to launch this year. It doesn’t end thereMany more missions planned for the 2022 and 2024 launch windows, and there are proposals to put humans on Mars by the 2030s.

List of Operational and Enroute Mission to Mars

Mars Odyssey, 2001:- It launched on April 7, 2001, and holds the record as the longest-operating spacecraft orbiting Mars. It is a NASA orbital satellite. currently, it is 2,400 miles above Mars’ surface. The mission of this satellite was to find proof of past or present water on Mars, using spectrometers and a thermal imager to map out the distribution of water, but it was successfully proven on 21st July 2008, by the Phoenix lander. It will remain in operation until 2025.

Mars Express, 2003:- It was launched by the European space agency on 2nd June 2003. Mars Express was launched with the purpose of surveying Mars’ surface using high-resolution cameras, radars, and spectrometers.

Mars Express has discovered water ice and carbon dioxide ice in Mars’ southern ice cap, along with an area of liquid water below, and has given the details of the elemental and chemical balance of the planet’s surface and atmosphere. It will carry on its operation until the end of 2026.

Mars Spirit and Opportunity, 2003:- It was launched in the year 2003 by NASA, This mission was launched to study the mars atmosphere and geology, Mars spirit had a pair of rovers, It gives us the data that Mars was much wetter than it is today.

Mars Reconnaissance Orbiter, 2005:-  On 12th August 2005 Nasa Lunced this spacecraft. The Mars Reconnaissance Orbiter has been observing the landscape and has made numerous high-profile discoveries, including the recent observance of flowing saltwater on the surface and subsurface of the planet.

Curiosity Rover, 2011:- It was also launched by NASA. It was made to study the landscape and climate of Mars, Curiosity is looking for potential evidence of microbial life-sustaining conditions. It’s most notable find so far is the discovery of organic molecules on the planet’s surface in 2018. 

Mangalyaan (Mars Orbiter Mission), 2013:- The Indian Space Research Organization (ISRO) launched its first mission on November 5, 2013. Mangalyaan is lashed with a small suite of research instruments designed to capture atmospheric data. It was the cheapest Mars mission to date, costing only $73 million in the U.S.

MAVEN, 2013:- MAVEN Mission full form is Mars Atmosphere and Volatile Evolution Mission (MAVEN) It’s objective is currently searching for explanations for how and why Mars’ water and atmosphere have been slowly deteriorating and escaping. it was able to confirm that Mars’ atmosphere broke out into space,

ExoMars Trace Gas Orbiter, 2016:- This mission was the result of the partnership between the European Space Agency and Russia’s Roscosmos The mission included two probes, the ExoMars Trace Gas Orbiter (TGO) and the Schiaparelli EDM Lander.

InSight Lander, 2018:- It was launched in 2018, In its first year, the lander enabled new findings of the weather, geology, and magnetic fields of the planet, but its investigations have been somewhat hindered by an ongoing problem with a stuck heat probe.

Hope Mars Mission, 2020:- It was Launched by the United Arab Emirates on 19 July 2020, Hope is scheduled to reach Mars in February 2021. This mission concentrated on understanding Mars weather and atmosphere

Tianwen-1, 2020 (China):- China has successfully launched its first interplanetary mission Tianwen-1 to Mars on 23 July, the spacecraft will reach Mars in February 2021. once the mission reaches Mars China could become just the second country to land and possess a rover on the Martian surface. This Spacecraft will work to study the geology of Mars and learn more about what might be hiding underneath the planet’s surface. Once they reach the Red Planet, all three spacecraft will work to study the geology of the red planet and learn more about what might be hiding under the planet’s surface.

Planned Missions for future

  • Perseverance Rover, 2020 (USA, NASA)
  • Rosalind Franklin, 2022 (ESA-Roscosmos)
  • Tera-hertz Explorer (TEREX), 2022 (Japan)
  • Mangalyaan 2 (Mars Orbiter Mission 2), 2024 (India, ISRO)
