India runs its space program through a civilian agency, ISRO, with a smaller and newer military space arm alongside it. The program is known for reaching the Moon and Mars on modest budgets, an approach that has drawn wide attention. As of 2026 it has landed near the lunar south pole, put a probe around Mars on its first attempt, and demonstrated the ability to destroy a satellite. A crewed program is in development.
India stands out less for any single mission than for the price of its missions. Doing hard things cheaply is the program’s signature, and it shapes how India competes in a field dominated by far larger budgets.
ISRO and India’s Civil Space Program
The Indian Space Research Organisation (ISRO) is the national agency that runs India’s civil space activity. It designs and builds satellites, operates the country’s launch vehicles, and plans the science and exploration missions. It grew from a program that once carried rocket parts on bicycles into one that competes on the global launch market.
ISRO earns much of its budget by launching satellites for other countries. Its rockets are cheaper than most competitors, so foreign governments and companies buy rides on them. On one 2017 flight, a single Indian rocket placed more than a hundred satellites into orbit at once, a record at the time. This commercial launch business funds part of the science program.
The PSLV and GSLV Rockets
India flies two main rocket families, the PSLV and the GSLV, and they carry most of what the country launches. The Polar Satellite Launch Vehicle (PSLV) is the reliable workhorse, used for Earth-observation satellites, the Mars mission, and the early Moon probes. Its long record of successful flights made it the rocket of choice for commercial customers.
The Geosynchronous Satellite Launch Vehicle (GSLV) is the heavier lifter, built to place larger communications satellites into high orbit. Its most capable version, sometimes called the GSLV Mark III or LVM3, lofted the Chandrayaan Moon missions and is the intended ride for India’s crewed program. Developing a domestic engine for it took years, which is why India relied on foreign rockets for heavy payloads earlier in its history.
Chandrayaan and the Moon
India’s lunar program, Chandrayaan, reached a milestone in 2023 that no other nation had. The Chandrayaan-3 mission soft-landed near the Moon’s south pole, making India the fourth country to land on the Moon and the first to reach that polar region. The south pole draws interest because it may hold water ice in permanently shadowed craters, a resource for any future base.
The success followed a public failure. The earlier Chandrayaan-2 lander crashed during its 2019 descent, though its orbiter survived and still maps the Moon. India rebuilt the lander design and tried again rather than abandoning the goal. The pattern of a setback followed by a corrected retry runs through several parts of the program.
Mangalyaan and Mars
India reached Mars on its first attempt, a feat no other nation had managed. The Mars Orbiter Mission, known as Mangalyaan, launched in 2013 and entered orbit around Mars in 2014. Reaching Mars is hard; many missions from established programs have failed, so a first-try success drew wide notice.
Mangalyaan also became the emblem of India’s low-cost approach. Its total cost was widely reported as less than the budget of some Hollywood space films, a comparison that stuck. The mission was modest in its instruments, but it proved India could navigate a probe across interplanetary space and insert it into orbit, capabilities only a handful of programs hold.
The Low-Cost Approach
India’s defining feature is doing hard missions cheaply, and the savings are real rather than a slogan. The Mars mission and the Moon landings cost a fraction of comparable Western efforts. This lets India attempt exploration that its budget would otherwise rule out, and it makes the country’s launch services attractive to paying customers.
The cost efficiency comes from a few concrete choices. India uses simpler mission designs, keeps instruments lean, reuses proven hardware instead of developing new systems each time, and benefits from lower domestic engineering and labor costs. The tradeoff is that Indian missions often carry fewer or lighter instruments than a flagship Western probe. A cheaper mission does less science, but India can afford to fly more of them.
Gaganyaan and Crewed Spaceflight
India is building a crewed program called Gaganyaan, aiming to launch its own astronauts into orbit. The plan uses a version of the LVM3 rocket and a new crew capsule, with uncrewed test flights preceding any human launch. As of 2026 the program is in active testing, so a crewed flight remains a stated goal rather than an achievement.
Success would put India in a small club. Only Russia, the United States, and China have launched humans into orbit on their own rockets. India joining would mark a shift from a program known for cheap robots to one that also flies people.
Military Space and the Defence Space Agency
India’s military space effort is younger than its civil program and grew quickly after 2019. That year India set up the Defence Space Agency, a tri-service body meant to coordinate military use of space across the army, navy, and air force. The move followed a recognition that satellites underpin modern communications, navigation, and reconnaissance, and that they could become targets.
The clearest signal of India’s military space intent was Mission Shakti in March 2019. India destroyed one of its own satellites in low orbit with a direct-ascent missile, becoming the fourth nation to demonstrate the ability to destroy a satellite. India chose a low altitude on purpose so most debris would re-enter and burn up quickly, a nod to the debris problem covered in our anti-satellite weapons explainer.
