ISRO's Launch Logjam And NavIC Woes Overshadow Gaganyaan Advances Amid Private Sector Surge

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.
| Mission | Rocket | Description / Significance |
|---|---|---|
| PSLV C62/EOS-N1 | PSLV | Earth Observation Mission; failed to complete its intended trajectory. |
| HLVM3-G1/OM1 | LVM3 (Human-Rated) | First uncrewed orbital test flight under the Gaganyaan program. |
| GSLV-F17/EOS-05 | GSLV | Earth Observation Mission utilizing the Geosynchronous Satellite Launch Vehicle. |
| PSLV C63/TDS-01 | PSLV | Technology Demonstration Satellite mission. |
| PSLV-N1/EOS-10 | PSLV | First PSLV realised by NSIL through a consortium of Indian industries. |
| SSLV-L1/NSIL | SSLV | Small Satellite Launch Vehicle mission managed by NewSpace India Ltd. |
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.
