India's space journey is nothing short of a cosmic saga, where every mission tells a story of ingenuity and resourcefulness. The Indian Space Research Organisation (ISRO) has captured the imagination of the world with its astonishing, budget-friendly space missions. Despite operating on a fraction of the funds available to its global peers, ISRO has consistently delivered extraordinary results, proving that great things can come from modest investments. Here’s a look at seven standout missions that highlight ISRO’s prowess in space exploration.

Mangalyaan: Mars on a Minimal Budget

In 2013, ISRO achieved a remarkable feat with the launch of Mangalyaan, the Mars Orbiter Mission (MOM). This mission cost just $74 million, a fraction of NASA’s Maven mission, which had a budget of $670 million.

• Mission Objectives: Chandrayaan-1 involved sending an orbiter to the Moon to map its surface and study its mineral composition.
• Historic Discovery: The mission made history by discovering water molecules on the lunar surface, which has significant implications for future lunar exploration.
• Comprehensive Mapping: The orbiter contributed to an extensive mapping of the Moon’s surface, providing crucial data for selecting future lunar landing sites.
• Cost Efficiency: Despite its modest budget, Chandrayaan-1 delivered results comparable to more expensive missions, such as NASA’s $500 million Lunar CRater Observation and Sensing

Chandrayaan-1: India’s Lunar Pioneer

Launched in 2008, Chandrayaan-1 marked India’s foray into lunar exploration. This mission, which cost $82 million, involved sending an orbiter to the Moon to map its surface and study its mineral composition.

• Objective: The orbiter was sent to map the Moon's surface and study its mineral composition.
• Historic Discovery: Chandrayaan-1 made history by discovering water molecules on the lunar surface, a groundbreaking finding for future lunar exploration.
• Mapping Contribution: The orbiter provided comprehensive mapping data of the Moon’s surface, aiding in the selection of landing sites for future missions.
• Comparison to Other Missions: Despite its modest budget, Chandrayaan-1 delivered results comparable to more expensive missions, such as NASA’s $500 million Lunar CRater Observation and Sensing Satellite.

PSLV: The Versatile Workhorse

The Polar Satellite Launch Vehicle (PSLV) has become ISRO’s most reliable and cost-effective launch vehicle. Since its debut, PSLV has been used to deploy a wide array of satellites into various orbits. Each launch, costing just $20 million, supports a diverse range of missions, from Earth observation to interplanetary exploration.
