Setback for India: PSLV-C62 Rocket Fails, Satellite Mission Ends in Loss

A High-Stakes Mission Ends in Setback

On January 12, 2026, a significant mission failure was reported by the Indian Space Research Organisation (ISRO) as the PSLV-C62 rocket did not achieve its intended orbit, resulting in the loss of the vital DRDO’s hyperspectral imaging satellite EOS-N1 (also referred to as Anvesha) along with 15 additional satellites that included advanced technologies. This was anticipated to be India’s inaugural orbital launch of the year, but the mission ended abruptly after an anomaly disrupted the rocket’s trajectory during the critical third stage.

The implications of this failure are vast, impacting national strategic capabilities, international customer trust, and the expanding Indian private space sector. In this report, we analyze what transpired, why it’s significant, and what lies ahead for ISRO and its collaborators.

The Mission at a Glance

The Launch and Its Purpose

The PSLV-C62 mission took off from the Satish Dhawan Space Centre’s First Launch Pad in Sriharikota, Andhra Pradesh, carrying 16 satellites in total, including both strategic payloads and commercial units from domestic and international sources.

The main payload was the EOS-N1 (Anvesha) Earth observation satellite developed with the Defence Research and Development Organisation (DRDO). As a hyperspectral imaging satellite, EOS-N1 was planned to enhance surveillance capabilities—vital for defence and civilian uses such as agriculture, environmental monitoring, and urban planning.

In addition to EOS-N1, several co-passenger payloads from space startups and international partners were included, showcasing innovative disruptive technologies in fields like on-orbit refuelling, artificial intelligence, and Earth imaging.

Technical Configuration of the Rocket

The vehicle was the PSLV-DL variant, which is known for its combination of solid and liquid stages alongside two strap-on boosters. This type represents one of India’s most dependable launch vehicles, designed to securely place its cargo into a sun-synchronous orbit at about 505–512 kilometers.

What Went Wrong? The Anomaly Explained

Third Stage Disturbance and Path Deviation

Initially, the rocket's ascent appeared sound, with both the first and second stages functioning as expected. However, complications arose during the third stage (PS3) burn, as telemetry indicated an unexpected disturbance and pressure drop, which caused a deviation from the predetermined flight path.

ISRO Chairman Dr. V. Narayanan confirmed that a significant anomaly occurred late in the third stage, hindering the vehicle from attaining the required orbital velocity and insertion. Consequently, none of the satellites on board could be deployed into their planned orbits.

Such a failure during the third stage is particularly challenging, given the critical operational stage when the rocket accelerates toward orbital velocity. A slight deviation can lead to severe consequences, as evidenced in this case.

The Technical Challenge and Investigation Ahead

ISRO has initiated a thorough analysis to uncover the root cause of the anomaly. Engineers and specialists are examining ground-station telemetry, system logs, and component data from all rocket stages to determine whether the issue was linked to manufacturing tolerances, integration challenges, or propulsion inconsistencies.

The agency has committed to transparency in its investigation and will publish detailed findings once the Failure Analysis Committee has completed its review.

Strategic and Scientific Significance of the Lost Payloads

DRDO’s EOS-N1 — The ‘Super-Eye’ Satellite

EOS-N1, also known as Anvesha, aimed to be a hyperspectral Earth-observation satellite capable of capturing images across a wide range of wavelengths—far surpassing traditional optical or infrared systems. Its potential applications included:

• Strategic defence surveillance

• Monitoring borders and maritime areas
