Aditya-L1 was launched in 2023 and was placed in a halo orbit around the first Lagrange point between the Earth and the Sun, a position from which the Sun can be watched without eclipses, and it carries instruments to study the corona, the solar wind and solar flares.

The spacecraft was launched by a PSLV in November 2013 and entered the orbit of Mars on 24 September 2014, which made India the first country to succeed at Mars on its first attempt and the first in Asia to reach Mars orbit.

Chandrayaan-1 was launched in 2008, carried the Moon Impact Probe and instruments from several countries, and its data showed the presence of water molecules on the lunar surface, which changed the understanding of the Moon.

The correct answer is A, Sriharikota, an island on the coast of Andhra Pradesh, from which PSLV, GSLV and LVM3 flights take off.

The headquarters of ISRO and of the Department of Space are at Bengaluru, where the U R Rao Satellite Centre and the telemetry and tracking network ISTRAC are also located.

The SLV-3 placed it in orbit on 18 July 1980 from Sriharikota, with A. P. J. Abdul Kalam as the mission director, and the flight made India a country able to launch its own satellites.

It was launched on 19 April 1975 from a Soviet launch site, was named after the astronomer of the fifth century and carried experiments in astronomy and solar physics.

ISRO was formed on 15 August 1969, taking over the work of the committee that had been running the programme.

He chaired the Indian National Committee for Space Research set up in 1962, chose Thumba for the first sounding rocket launches and argued that a poor country needed space technology for communication, education and weather rather than for prestige.

It is the second of the three Yudh Seva medals instituted in 1980, below the Sarvottam Yudh Seva Medal and above the Yudh Seva Medal.

The two lists are announced on 26 January and on 15 August, and the medals are presented later at investiture ceremonies by the President, who is the Supreme Commander of the armed forces.

The series has three grades, the Sarvottam Jeevan Raksha Padak, the Uttam Jeevan Raksha Padak and the Jeevan Raksha Padak, and it is administered by the Ministry of Home Affairs and open to civilians, including children.

The Sena Medal, the Nao Sena Medal and the Vayu Sena Medal were instituted in 1960 for individual acts of gallantry or exceptional devotion to duty, one for each service, and the word Nao in the name marks the Navy just as Vayu marks the Air Force.

He was awarded the Param Vir Chakra posthumously for the action at Badgam in Kashmir in November 1947, during the first conflict after independence, and the medal itself was instituted on 26 January 1950 with effect from 15 August 1947.

It is the highest peacetime gallantry award and is given for the most conspicuous bravery or self-sacrifice away from the field of battle, to members of the armed forces and to civilians alike.

The three grades of the series are worded exactly this way and questions are set on the wording alone: the most exceptional order for the Param Vishisht Seva Medal, an exceptional order for the Ati Vishisht Seva Medal and a high order for the Vishisht Seva Medal.

The three medals were instituted in 1980 and follow the same three steps as the Vishisht Seva medals, but the word Yudh in the name shows that they belong to wartime service rather than peacetime service.

The medal was instituted in that year in three classes, and in 1967 the classes were given the separate names Param Vishisht Seva Medal, Ati Vishisht Seva Medal and Vishisht Seva Medal.

It is given for distinguished service of the most exceptional order, and the word Param marks the top step of every Indian series of decorations.

Project Elephant was launched in 1992 to protect elephants, their habitat and the corridors along which herds move between forests, and it also deals with human elephant conflict and the welfare of captive elephants.
