Mars Lander Mission (MLM) or Mangalyaan-2, is a proposed second mission to Mars by the Indian Space Research Organisation (ISRO). [3]
Following the successful insertion of the Mars Orbiter Mission (also called Mangalyaan) into Martian orbit, ISRO announced its intent to launch a second mission to Mars at the Engineers Conclave conference held in Bengaluru on 28 October 2014. [6] The proposed launch vehicle for this campaign is the LVM3, which flew for the first time on 5 June 2017, and might be powerful enough to place MOM on a direct-to-Mars trajectory alongside much heavier satellites, unlike the lighter Mars Orbiter Mission, which used a less powerful PSLV XL rocket. [7]
In January 2016, India and France signed a letter of intent for ISRO and CNES to jointly build MOM 2 by 2020, [8] but by April 2018, France was not yet involved in the mission. [9] The Indian government funded MOM 2 in its 2017 budget proposal, and ISRO was considering whether the best path would be to conduct an orbiter/lander/rover mission or to opt for only an orbiter with more sophisticated instruments than those flown on MOM. [10] In a podcast recording, Vikram Sarabhai Space Centre director S. Somanath in October 2019 reported the architecture for mission was yet to be finalized and may also have a lander and rover, but no timeline was announced. [2]
In February 2021, ISRO called for an 'Announcement of Opportunities' on MOM 2. In it, K. Sivan announced that Mangalyaan 2 will only be an orbiter mission. [11] [12] Being launched by the LVM3 rocket (formerly the GSLV mk III), and using Aerobraking the MOM-2 satellite can carry more than 7 times the payload for MOM-1, also with a reduction in perigee to about 200 km above the surface of Mars. [13]
In a recorded interview in October 2019, the Vikram Sarabhai Space Centre (VSSC) director indicated the possibility of inclusion of a lander, [2] but in an interview to The Times of India in February 2021 the ISRO chairman clarified that the mission will consist solely of an orbiter. [14] The orbiter will use aerobraking to lower its initial apoapsis and enter into an orbit more suitable for observations. [15] [16] [10]
In 2024, the mission plan was updated, and now includes a rover, helicopter, sky crane and a supersonic parachute. [4]
An Announcement of Opportunity was released requesting submissions for scientific instruments for an orbiter only, with a deadline set for 20 September 2016. [17] [18] The total science payload mass is estimated at 100 kg (220 lb). [1]
One of the science payloads under development is an ionosphere plasma instrument named ARIS. It is being developed by Space Satellite Systems and Payloads Centre (SSPACE), which is part of the Indian Institute of Space Science and Technology (IIST). The engineering model and high vacuum test have been completed. [19]
In a panel discussion in September 2022, it was told that mission would include a hyperspectral camera, a very high resolution panchromatic camera and a radar to better understand the early stages of Mars, its early crust, recent basalts, and ongoing activities such as boulder falls. [20]
The mission will consist of four main payloads. [21]
The Polar Satellite Launch Vehicle (PSLV) is an expendable medium-lift launch vehicle designed and operated by the Indian Space Research Organisation (ISRO). It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into Sun-synchronous orbits, a service that was, until the advent of the PSLV in 1993, only commercially available from Russia. PSLV can also launch small size satellites into Geostationary Transfer Orbit (GTO).
The Indian Space Research Organisation is India's national space agency. It serves as the principal research and development arm of the Department of Space (DoS), overseen by the Prime Minister of India, with the Chairman of ISRO also serving as the chief executive of the DoS. It is primarily responsible for space-based operations, space exploration, international space cooperation and the development of related technologies. The agency maintains a constellation of imaging, communication and remote sensing satellites. It operates the GAGAN and IRNSS satellite navigation systems. It has sent three missions to the Moon and one mission to Mars.
ExoMars is an astrobiology programme of the European Space Agency (ESA).
Mylswamy Annadurai is an Indian scientist working as vice president for Tamil Nadu State Council for Science and Technology, Chairman, Board of Governors, National Design and Research Forum. He is often dubbed as the "Moon Man of India".
Indian Deep Space Network (IDSN) is a network of large antennas and communication facilities operated by the Indian Space Research Organisation to support the interplanetary spacecraft missions of India. Its hub is located at Byalalu, Ramanagara in the state of Karnataka in India. It was built under the leadership of S K Shivakumar, the then ISTRAC Director and inaugurated on 17 October 2008 by the former ISRO chairman G. Madhavan Nair.
Chandrayaan-2 is the second lunar exploration mission developed by the Indian Space Research Organisation (ISRO) after Chandrayaan-1. It consists of a lunar orbiter, the Vikram lunar lander, and the Pragyan rover, all of which were developed in India. The main scientific objective is to map and study the variations in lunar surface composition, as well as the location and abundance of lunar water.
K. Radhakrishnan a.k.a. Koppillil Radhakrishnan is an Indian space scientist who headed the Indian Space Research Organisation (ISRO) as Chairman of Space Commission, Secretary of the Department of Space, Government of India. Under his leadership, India became the first country to reach Mars in its first attempt.
Mars Orbiter Mission (MOM), unofficially known as Mangalyaan, was a space probe orbiting Mars since 24 September 2014. It was launched on 5 November 2013 by the Indian Space Research Organisation (ISRO). It was India's first interplanetary mission and it made ISRO the fourth space agency to achieve Mars orbit, after Soviet space program, NASA, and the European Space Agency. It made India the first Asian nation to reach Martian orbit and the second national space agency in the world to do so on its maiden attempt after the European Space Agency did in 2003.
Aluru Seelin Kiran Kumar is an Indian space scientist and former chairman of the Indian Space Research Organisation, having assumed office on 14 January 2015. He is credited with the development of key scientific instruments aboard the Chandrayaan-1 and Mangalyaan space crafts. In 2014, he was awarded the Padma Shri, India's fourth highest civilian award, for his contributions to the fields of science and technology. Kiran Kumar previously served as Director of Ahmedabad Space Applications Centre.
