Vikram Sarabhai is widely regarded as the father of Indian Aerospace Engineering. He played a pivotal role in establishing the Indian Space Research Organization (ISRO) and laid the foundation for India's space program.

The Indian Space Research Organization (ISRO) is the primary space agency of India. It is responsible for the country's space program, including satellite launches, space exploration missions, and the development of space technologies.

The Indian Space Research Organization (ISRO) was established in 1969 by the Government of India. It was formed by merging the Indian National Committee for Space Research (INCOSPAR) and the Thumba Equatorial Rocket Launching Station (TERLS).

Aryabhata was the first Indian satellite to be launched into space. It was named after the renowned Indian mathematician and astronomer Aryabhata. The satellite was launched on April 19, 1975, from the Satish Dhawan Space Centre in Sriharikota.

The primary objective of the Chandrayaan-1 mission was to study the lunar surface and atmosphere. The mission aimed to gather data on lunar topography, mineralogy, and elemental composition, as well as to search for water and other resources on the Moon.

Rakesh Sharma became the first Indian to travel to space in 1984. He was part of the Soviet Union's Soyuz T-11 mission, which launched from the Baikonur Cosmodrome in Kazakhstan.

The CE-20 Engine is India's first indigenously developed cryogenic engine. It is a high-performance rocket engine that uses liquid hydrogen and liquid oxygen as propellants. The engine was successfully tested in 2017 and is expected to power India's future heavy-lift launch vehicles.

INSAT-3D is an Indian satellite used for weather forecasting and disaster management. It was launched in 2013 and carries a variety of instruments for monitoring weather conditions, including a six-channel imager, a sounder, and a scatterometer.

The Reusable Launch Vehicle (RLV) is India's first reusable launch vehicle. It is being developed by the Indian Space Research Organization (ISRO) and is intended to reduce the cost of space access by enabling the reuse of rocket boosters.

INSAT-4A is an Indian satellite used for communication purposes. It was launched in 2005 and provides a variety of communication services, including television broadcasting, telephony, and internet connectivity.

Vikram is India's first lunar rover. It was part of the Chandrayaan-2 mission, which was launched in 2019. The rover was designed to explore the lunar surface and gather data on its composition and structure.

IRNSS-1A is an Indian satellite used for navigation purposes. It was launched in 2013 and is part of the Indian Regional Navigation Satellite System (IRNSS), which provides accurate positioning and navigation services over India and the surrounding region.

Mangalyaan is India's first interplanetary mission. It was launched in 2013 and successfully reached Mars in 2014. The mission aimed to study the Martian atmosphere, surface, and mineralogy.

Resourcesat-1 is an Indian satellite used for earth observation purposes. It was launched in 2003 and provides data on land use, vegetation, water resources, and other environmental parameters.

Gaganyaan is India's first space station. It is currently under development and is expected to be launched in 2023. The space station will be used for conducting scientific experiments, spacewalks, and other space-related activities.
