The Physical Research Laboratory (PRL) in Ahmedabad, India, is a major partner in the International Cometary Explorer (ICE) mission. PRL provided the spacecraft's imaging system and participated in the mission's scientific investigations.

The primary objective of the Indo-US Collaborative Cometary Research Program was to study the composition and structure of comets. The program involved joint research projects between Indian and American scientists, using data from various spacecraft missions and ground-based observations.

Dr. R. Rajamohan, an Indian astronomer from the Indian Institute of Astrophysics (IIA), played a key role in the discovery of Comet Hale-Bopp in 1995. He was part of an international team of astronomers who observed the comet using the Hubble Space Telescope and other ground-based telescopes.

The Comet Interceptor is an Indian spacecraft that was planned to be sent to a comet. The mission was intended to study the composition and structure of a comet in detail, and to investigate the processes that occur in the comet's coma and tail. However, the mission was later canceled due to budgetary constraints.

The Indian Institute of Astrophysics (IIA) in Bangalore, India, is a partner in the European Space Agency's (ESA) Rosetta mission. IIA provided scientific expertise and participated in the mission's planning and operations.

The Comet Interceptor was a joint Indo-Russian cometary research mission that was proposed in the early 2000s. The mission was intended to study the composition and structure of a comet in detail, and to investigate the processes that occur in the comet's coma and tail. However, the mission was later canceled due to budgetary constraints.

Dr. C.R. Kitchlu, an Indian astrophysicist, was involved in the development of the dust coma model for comets. His work helped to explain the observed properties of cometary comae, including their size, shape, and brightness.

The Cometary Dust Analyzer (CDA) was an Indian cometary research instrument that was flown on the Chandrayaan-1 mission. The CDA was designed to study the composition and properties of cometary dust particles.

The Physical Research Laboratory (PRL) in Ahmedabad, India, is a partner in the NASA-led Deep Impact mission. PRL provided the spacecraft's imaging system and participated in the mission's scientific investigations.

The primary objective of the Indo-Japanese Collaborative Cometary Research Program was to study the composition and structure of comets. The program involved joint research projects between Indian and Japanese scientists, using data from various spacecraft missions and ground-based observations.

Dr. U.R. Rao, an Indian space scientist, played a key role in the development of the ion tail model for comets. His work helped to explain the observed properties of cometary ion tails, including their length, shape, and brightness.
