The Indian Space Research Organisation (ISRO) has faced a significant hurdle in its 2026 operational schedule, failing to meet a series of mission deadlines previously outlined by the Union Government. In December 2025, it was announced that seven major missions were slated for completion by March 2026; however, only the LVM3 M6 mission by NewSpace India Ltd (NSIL) successfully reached orbit on Christmas Eve.

The remaining six missions, slated for the first quarter of 2026, have yet to materialise. These include PSLV C62/EOS-N1, which failed to achieve its intended trajectory. HLVM3-G1/OM1, the inaugural uncrewed test flight for the Gaganyaan human spaceflight programme, remains grounded.

Further pending launches are GSLV-F17/EOS-05, PSLV C63/TDS-01, and PSLV-N1/EOS-10—the first PSLV built by NSIL via an Indian industry consortium. SSLV-L1/NSIL rounds out the list. With March's deadline passed, these setbacks highlight logistical and technical hurdles at ISRO.

The remaining missions were scheduled to be launched in the first three months of 2026. Here's a quick ready reckoner:

A significant blow has struck the NavIC system, India's indigenous regional navigation network. Only three of its satellites now boast functional atomic clocks, falling short of the four needed for full GPS-like positioning and navigation services. The IRNSS-1F satellite, launched in March 2016, saw its clock fail on 13 March 2026, three days after completing its 10-year design life.

ISRO has repurposed IRNSS-1F for one-way broadcast messaging, such as storm forecasts. This development undermines NavIC's reliability, originally designed to deliver precise navigation independent of foreign systems.

Amid these challenges, progress continues in key areas. In March 2026, ISRO conducted a successful sea-level hot test of the CE20 cryogenic engine, delivering 22 tonnes of thrust with a novel nozzle protection system and multi-element igniter. This engine powers the LVM3 rocket's third stage and stands qualified for Gaganyaan.

To boost LVM3 payload capacity, ISRO plans an uprated third stage for future missions. On the human spaceflight front, ISRO has partnered with the All India Institute of Medical Sciences (AIIMS) for space medicine research. This collaboration targets ground and orbital studies to safeguard astronaut health.

Focus areas include human physiology, behavioural health, immunology, gut microbiology, biomedical science, neuroscience, nutrition, musculoskeletal atrophy in microgravity, infectious disease control, and performance countermeasures. Such expertise will support long-duration missions like the Bharatiya Antariksh Station and lunar crewed flights, while advancing national healthcare.

Internationally, ISRO and the European Space Agency (ESA) signed an agreement for joint calibration, validation, and scientific studies on Earth observation missions. This builds on their cooperation since 1978, fostering shared technological advancements.

Parliamentary scrutiny has intensified. The Standing Committee on Science and Technology, in its report on Demands for Grants (2026-27) for the Department of Space, voiced concerns over undervalued technology transfers to private entities. It criticised low pricing relative to commercial potential, allowing firms to reap disproportionate profits.

The Committee urged a shift to competitive, market-aligned pricing frameworks. This reflects broader tensions in India's space sector liberalisation, balancing public investment with private gains.

Private players are pushing boundaries. Agnikul Cosmos achieved a milestone with its Agnibaan engine test. Notably, its engines are fully 3D-printed in just seven days, slashing production timelines from months and simplifying manufacturing.

Bellatrix Aerospace secured a $20 million pre-series B funding round, led by Cactus Partners. This infusion will hasten the commercial rollout of its propulsion systems, bolstering in-space mobility solutions.

Samtel Avionics is venturing into space and drones with over ₹200 crore investment. It aims to develop low Earth orbit (LEO) and miniature satellites, with its debut space project imminent. The firm also eyes space debris management opportunities.

These developments underscore India's evolving space ecosystem. While ISRO contends with delays and NavIC woes, engine tests, medical partnerships, and private innovations signal resilience. Strategic pricing reforms could unlock greater value from public R&D, propelling the nation towards self-reliance in space.
