MESSENGER (an acronym of MErcury Surface, Space ENvironment, GEochemistry and Ranging) is a robotic NASA spacecraft orbiting the planet Mercury, the first spacecraft ever to do so. The 485-kilogram spacecraft was launched aboard a Delta II rocket in August 2004 to study Mercury’s chemical composition, geology, and magnetic field. It became the second mission after 1975’s Mariner 10 to reach Mercury successfully when it made a flyby in January 2008, followed by a second flyby in October 2008, and a third flyby in September 2009.

The Greenhouse Gases Observing Satellite or GOSAT, also known as Ibuki (meaning breath in Japanese) is an Earth observation satellite and the world’s first satellite dedicated to greenhouse-gasmonitoring. It measures densities of carbon dioxide and methane from 56,000 locations on the Earth’s atmosphere. The GOSAT was developed by the Japan Aerospace Exploration Agency (JAXA) and launched on January 23, 2009, from the Tanegashima Space Center. Japan’s Ministry of the Environment, and National Institute for Environmental Studies (NIES) use the data to track gases causing the greenhouse effect, and share the data with NASA and other international scientific organizations. Note : On Dec. 22, 2016 China has successfully sent its first carbon dioxide monitoring satellite TanSat into space via a Long March-2D rocket. The spacecraft was launched from the Jiuquan Satellite Launch Center located in the Gobi Desert.

The Indian Space Research Organisation (ISRO) is the primary space agency of the Indian government. ISRO is amongst the six largest government space agencies in the world, along with NASA, RKA, ESA, CNSA and JAXA. Its primary objective is to advance space technology and use its applications for national benefit. Established in 1969, ISRO superseded the erstwhile Indian National Committee for Space Research (INCOSPAR). Headquartered in Bangalore, ISRO is under the administrative control of the Department of Space, Government of India. ISRO has achieved numerous milestones since its establishment. India’s first satellite, Aryabhata, was built by ISRO and launched by the Soviet Union in 1975. Rohini, the first satellite to be placed in orbit by an Indianmade launch vehicle, SLV-3, was launched in 1980. ISRO subsequently developed two other rockets: the Polar Satellite Launch Vehicle (PSLV) for putting satellites into polar orbits and the Geosynchronous Satellite Launch Vehicle (GSLV) for placing satellites into geostationary orbits. These rockets have launched numerous communications satellites, earth observation satellites, and, in 2008, Chandrayaan-1, India’s first mission to the Moon.

Kaiga generating station is a nuclear power generating station situated at Kaiga, near the river Kali, in Uttar Kannada district of Karnataka, India. The plant has been in operation since March 2000 and is operated by the Nuclear Power Corporation of India. It has four units. The fourth unit went critical on 27 November 2010. The two oldest units comprise the west half of the site and the two newer units are adjoining the east side of the site. All of the four units are small-sized CANDU plants of 220 MW.
