ISRO & Global Space Agencies

          1. ISRO (India) - Indian Space Research Organisation

 India's prestigious agency, known for delivering best results at low costs.

History and Development of ISRO

• Beginning: India's space program started under the leadership of Dr. Vikram Sarabhai, who is considered the 'Father of the Indian Space Program'.
• Establishment: 'INCOSPAR' was established in 1962, which later became 'ISRO' in 1969.
• First Satellite: On April 19, 1975, India launched its first satellite, 'Aryabhata' (with help from the Soviet Union).
• Indigenous Rocket: In 1980, India created history by launching the 'Rohini' satellite using its own rocket, SLV-3.

Launch Vehicles of ISRO

• PSLV: Known as the 'Workhorse' of ISRO, it is extremely reliable.
• GSLV: Used to launch heavy satellites into high Earth orbits.
• LVM3: India's most powerful rocket, used in the Chandrayaan-3 mission.
• SSLV: A new rocket for launching small satellites quickly and at a low cost.

Historic Missions

• Chandrayaan-1 (2008): This mission discovered water molecules on the Moon.
• Mangalyaan (MOM - 2013): India became the first country in the world to reach Mars' orbit in its first attempt.
• 104 Satellites (2017): Created a world record by launching 104 satellites with a single rocket (PSLV-C37).
• Chandrayaan-3 (2023): India became the first country in the world to achieve a soft landing on the Moon's South Pole.

Ambitious Projects

• Gaganyaan: India's first human spaceflight mission, preparing to send Indian astronauts (Gaganauts) into space.
• Aditya-L1: India's first dedicated mission to study the Sun.
• Shukrayaan: Planned mission to research the planet Venus.
• NISAR: A joint mission between NASA and ISRO to monitor Earth's changing environment.

Role of ISRO in the Economy

ISRO contributes significantly to the country's progress beyond science:

• Agriculture: Satellite-based crop monitoring and weather forecasting.
• Disaster Management: Saving thousands of lives by providing early warnings of disasters like cyclones or floods.
• Education and Telemedicine: Providing education and health services to remote villages.
• Navigation: Developed 'NavIC', India's own GPS-like system.

ISRO's greatest strength is its simplicity and efficiency, making India a 'Superpower' in space science.
