China Mars mission Tianwen-1
Part of: GS-III- S&T Space (PT-MAINS-PERSONALITY TEST)
Aiming to catch up with India, U.S., Russia and the European Union to reach the red planet, China’s Mars mission plans to complete orbiting, landing and roving in one mission
China named its first Mars exploration mission to be launched later this year as Tianwen-1 as it celebrated Space Day to mark the 50th anniversary of the launch of the country’s first satellite Dong Fang Hong-1 in 1970.
China in recent years has emerged as a major space power with manned space missions and landing a rover in the dark side of the moon. It is currently building a space station of its own.
However, China’s attempts to send an exploratory probe to Mars called Yinghuo-1, in a Russian spacecraft in 2011 failed as shortly after the launch and it was declared lost and later burnt during re-entry.
The U.S., Russia, the EU besides India so far succeeded in sending missions to Mars regarded as the most complex space mission.
India became the first Asian country to have successfully launched its Mars orbiter mission, Mangalyaan which has entered the orbit of the red planet in 2014.
India also became the first country to have entered the Martian orbit in its first attempt.
About MARS (PT SHOT)
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury. In English, Mars carries the name of the Roman god of war and is often referred to as the 'Red Planet'. The latter refers to the effect of the iron oxide prevalent on Mars' surface, which gives it a reddish appearance distinctive among the astronomical bodies visible to the naked eye. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth.
There are ongoing investigations assessing the past habitability potential of Mars, as well as the possibility of extant life. Future astrobiology missions are planned, including the Perseverance and Rosalind Franklin rovers. Liquid water cannot exist on the surface of Mars due to low atmospheric pressure, which is less than 1% of the Earth's, except at the lowest elevations for short periods. The two polar ice caps appear to be made largely of water. The volume of water ice in the south polar ice cap, if melted, would be sufficient to cover the entire planetary surface to a depth of 11 meters (36 ft). In November 2016, NASA reported finding a large amount of underground ice in the Utopia Planitia region of Mars. The volume of water detected has been estimated to be equivalent to the volume of water in Lake Superior.
Mars Orbiter Mission (MOM) or Mission Mangalyaan is the first interplanetary space mission of Indian Space Research Organisation (ISRO). It was successfully launched on 5th November 2013. The space probe of this mission has been orbiting the Mars since 24th September 2014. Some of the highlights of this successful mission was
Which was the Launch Vehicle used for Mars Orbiter Mission?
Mars Orbiter Mission (MOM) was launched using Polar Satellite Launch Vehicle (PSLV XL – C25) from Satish Dhawan Space Centre, Sriharikota, Nellore District of Andhra Pradesh. It took 298 days for the Mars probe to reach the orbit of Mars. The probe is being tracked from ISRO centres located in Bangalore.
What were the Objectives of Mars Orbiter Mission (MOM)?
The primary objective was to develop the necessary technologies for interplanetary space missions. The other objectives were
What were the Scientific Instruments Carried on the MOM mission?
Payload in the Mars Orbiter Mission (MOM) was made of 5 scientific instruments.
