ISRO's Upcoming Space Programs

A Comprehensive Guide to India's Galactic Ambitions (2026–2035)

The Indian Space Research Organisation (ISRO) has rapidly evolved from a developing nation's space agency into a global heavyweight in space exploration. Following the monumental achievements of the Chandrayaan-3 lunar landing and the Aditya-L1 solar observatory, ISRO is now gearing up for a transformative era. Over the next decade, India's space roadmap shifts focus toward human spaceflight, deep-space planetary exploration, and the establishment of an independent space station.

The period from 2026 to 2035 is packed with groundbreaking missions, including crewed flights, Venus orbiters, Mars landers with aerial vehicles, and complex lunar sample return operations. This article delves into the intricate details of ISRO's upcoming space programs, exploring their scientific objectives, technological innovations, payloads, and launch timelines.

1. Gaganyaan: India's Human Spaceflight Programme

At the absolute forefront of ISRO's immediate future is the Gaganyaan mission, representing India's inaugural human spaceflight program. The mission's core objective is a massive technological leap: to demonstrate indigenous capability to undertake human spaceflight to Low Earth Orbit (LEO) safely and efficiently.

• The Objective: Launch a crew of three Indian astronauts to an orbit of 400 km for a 3-day mission, followed by a safe splashdown in Indian sea waters.
• Timeline & Test Flights: Before risking human lives, ISRO will conduct uncrewed test flights. Gaganyaan-1, Gaganyaan-2, and Gaganyaan-3 are scheduled through 2026 as vital technology demonstrators.
• The Launch Vehicle: The reliable Launch Vehicle Mark 3 (LVM3) has been meticulously reconfigured into the Human-Rated LVM3 (HLVM3) to meet stringent safety standards.
• Global Significance: Upon successful completion, India will become only the fourth nation in the world—after the United States, Russia, and China—to launch humans into space independently.

2. Bharatiya Antariksha Station (BAS)

Moving beyond brief human spaceflights, India has charted a monumental course toward establishing its own modular space station. The Bharatiya Antariksha Station (BAS) was formally approved by the Union Cabinet in late 2024, supported by a massive funding allocation of ₹20,193 crore (inclusive of the Gaganyaan expansion).

Orbiting at an altitude of 400-450 km, BAS will serve as an advanced research hub for microgravity experiments across physics, biology, materials science, and space medicine. It will allow Indian astronauts to stay in space for extended durations of three to six months.

Module Name	Expected Launch	Primary Function
BAS-01 (Base Module)	2028	Houses crew quarters, life support systems, and docking ports (9-10 tonnes).
BAS-02 to BAS-05	By 2035	Includes Core Control, Science Labs, and Common Berthing extensions.

3. Shukrayaan-1: Venus Orbiter Mission (VOM)

Expanding its planetary horizons, ISRO is setting its sights on Earth’s "evil twin," Venus, through the highly anticipated Shukrayaan-1 mission (Venus Orbiter Mission). Despite being roughly the same size as Earth, Venus features a crushing atmosphere of carbon dioxide, sulfuric acid clouds, and surface temperatures around 460°C. Studying Venus is critical for modeling Earth's future climate and understanding planetary habitability.

Mission Specifications:

• Launch Date: Scheduled for March 29, 2028. The spacecraft will undertake a 112-day journey to enter Venusian orbit on July 19, 2028.
• Budget: ₹1,236 crore.
• Launch Vehicle: Heavy-lift upgraded LVM-3 rocket.
• Payloads: 19 distinct scientific instruments (16 Indian, 3 international). Key instruments include the VSAR (Venus S-Band Synthetic Aperture Radar) to map the surface through thick clouds, and a Sub-Surface Radar, marking the first time any global space agency attempts a ground-penetrating radar study of Venus.

4. Mangalyaan-2: Mars Lander Mission

Following the historic success of the Mars Orbiter Mission (MOM) in 2014, ISRO is exponentially scaling up its Martian ambitions with Mangalyaan-2. Unlike its predecessor, which was strictly an orbital mission, Mangalyaan-2 represents a colossal technological leap.

ISRO plans to deploy a complete package: a Mars Orbiter, a Lander, a surface Rover, and incredibly, a Martian Helicopter. Landing on Mars—often referred to as the "seven minutes of terror"—is notoriously difficult due to its thin atmosphere. ISRO is developing specialized mechanisms, including a "sky crane", to safely lower the 4,500 kg payload onto the red dust.

While initially slated for the 2026-2030 window, the intricate development of planetary descent stages means the launch will occur later in the decade. If successful, Mangalyaan-2 will make India one of the rare nations capable of conducting direct surface operations on another planet.

5. Chandrayaan-4 (Sample Return)

Targeted for 2027, Chandrayaan-4 aims to land on the Moon, extract regolith (soil and rocks), and safely transport the samples back to Earth. Because of the extreme weight of a return vehicle, the mission will be highly complex, featuring four separate modules (Transfer, Lander, Ascender, and Reentry). It will require dual launches (using LVM3 and PSLV) and orbital assembly before heading to the Moon—a massive first for ISRO.

6. LUPEX (Lunar Polar Exploration)

Scheduled for the 2028–2029 timeframe, LUPEX is a massive joint venture between ISRO and Japan’s space agency, JAXA. ISRO will supply the lunar lander, while JAXA provides the H3 launch vehicle and the rover. The mission will explore the permanently shadowed regions of the lunar south pole, deploying advanced drills to extract sub-surface samples and search for water ice—a crucial resource for future human lunar bases.

7. NISAR: NASA-ISRO Synthetic Aperture Radar

No discussion of ISRO's future is complete without NISAR. Launched by the GSLV-F16 in July 2025, this massive Earth-observing satellite is now entering its critical operational science phase for the remainder of the decade.

Representing one of the most expensive and advanced collaborations between NASA and ISRO, NISAR utilizes dual frequencies (NASA’s L-band and ISRO’s S-band) to comprehensively map Earth's dynamic surfaces. From monitoring groundwater depletion and tracking shifting ice sheets in Antarctica to assessing agricultural biomass and disaster zones, NISAR's data is fundamentally altering global climate science and hazard management.

8. The Backbone: Next Generation Launch Vehicle (NGLV)

To support these massive payloads—including the space station modules and heavy planetary explorers—ISRO is developing the Next Generation Launch Vehicle (NGLV), named Surya. While the current heavy lifter (LVM3) maxes out around 10 tonnes to LEO, NGLV aims to triple this capacity to 30 tonnes. Crucially, the NGLV will feature reusable first stages, drastically cutting launch costs and serving as the foundational rocket for India's ultimate goal: landing an Indian on the Moon by 2040.

Conclusion

The upcoming decade is arguably the most transformative period in the history of the Indian Space Research Organisation. From sending astronauts into orbit aboard Gaganyaan to deploying advanced aerial vehicles on Mars, and from establishing an indigenous space station to probing the toxic clouds of Venus, ISRO’s roadmap is nothing short of spectacular. These upcoming space programs represent more than scientific curiosity; they are a testament to India's technological self-reliance, its strategic geopolitical positioning, and its commitment to unraveling the profound mysteries of the cosmos. As we head toward 2030, the entire globe will undoubtedly be watching Sriharikota closely.
