GalaxEye Launches World's First OptoSAR Satellite Aboard SpaceX Falcon 9, Marking India's Largest Privately Built Earth Observation Spacecraft

Bengaluru-based GalaxEye flew Mission Drishti, a 190-kilogram OptoSAR satellite fusing radar and multispectral optics, on a SpaceX Falcon 9 rideshare from Vandenberg.

Overview

Bengaluru space startup GalaxEye placed its Mission Drishti satellite into orbit on May 3, 2026, aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California, according to News On AIR. The 190-kilogram spacecraft is described by News On AIR as “the world’s first OptoSAR satellite” and “the largest Earth observation satellite ever built by a private Indian company.”

The satellite flew as one of 44 secondary payloads on SpaceX’s CAS500-2 rideshare mission, which carried a total of 45 spacecraft including the primary Compact Advanced Satellite 500-2 from Korea Aerospace Industries, as reported by Spaceflight Now.

What We Know

  • Liftoff from Space Launch Complex 4 East at Vandenberg occurred at 12 a.m. PDT (0700 UTC), per Spaceflight Now, which corresponds to roughly 12:30 PM IST, according to GK Now.
  • Falcon 9 first stage booster B1071 completed its 33rd flight on the mission and landed at Landing Zone 4 adjacent to the pad it launched from, Spaceflight Now reported. Rideshare integrator Exolaunch coordinated most secondary payloads, deploying 21 CubeSats and 18 MicroSats, the same outlet noted.
  • The OptoSAR payload combines an X-band synthetic aperture radar sensor with a seven-band multispectral imager on a single thermally stable optical bench, Analytics Drift reported, producing data the outlet describes as “three times richer in information than a standalone sensor, at 1.8-meter fused resolution.”
  • GK Now reports a combined SAR-and-optical resolution range of 1.2 to 3.6 metres and notes the spacecraft carries a deployable 3.5-metre radar antenna and an electric propulsion system, operating in a sun-synchronous low-Earth orbit at roughly 500 kilometres of altitude.
  • The fusion approach is intended to compensate for the trade-offs of each sensor type. SAR can image through clouds and at night but produces coarser data, while optical imaging captures more intuitive multispectral views but fails in poor visibility, per GK Now.

The Company and Its Distribution Plan

GalaxEye is a Bengaluru-based startup founded by IIT Madras alumni, with Suyash Singh serving as chief executive and Denil Chawda as chief technology officer, The Tribune reported. Analytics Drift names the founding team as “five IIT Madras alumni including CEO Suyash Singh, CTO Denil Chawda, Kishan Thakkar, Pranit Mehta, and Rakshit Bhatt.”

For commercialization, the company has partnered with NewSpace India Limited (NSIL), the commercial arm of the Indian Space Research Organisation, for global distribution of its imagery, Analytics Drift reported. The Tribune characterizes the NSIL partnership as a “landmark” arrangement for satellite imagery distribution.

Roadmap

Analytics Drift reports that GalaxEye “plans a full OptoSAR constellation by 2028 aimed at providing daily global coverage,” and notes that second-generation satellites “targeting 300 kilograms with 0.5-meter resolution are in preliminary design.”

Government Reaction

Prime Minister Narendra Modi said in a public statement that “Mission Drishti by GalaxEye marks a major achievement in our space journey. The successful launch of the world’s first OptoSAR satellite and the largest privately-built satellite in India is a testament to our youth’s passion for innovation and nation-building,” The Tribune reported.

Vice President C.P. Radhakrishnan said the mission “marks a significant step forward for India’s commercial space ecosystem,” according to News On AIR.

What We Don’t Know

  • First operational imagery from Drishti has not yet been published. Reviewed sources do not specify a date for first-light release of OptoSAR data.
  • Sources differ on GalaxEye’s incorporation date — some place the founding in 2020, others in 2021 — and on whether the planned constellation comprises a specific number of satellites; Analytics Drift states only that the full OptoSAR constellation is targeted for 2028.
  • Pricing for NSIL-distributed imagery, end-user contracts, and government customers have not been disclosed in the cited reporting.
