Contact lost with Drishti, world’s first OptoSAR satellite
  • Mission Drishti, built by Bengaluru start-up GalaxEye, is the world's first OptoSAR satellite — fusing Electro-Optical (EO) and Synthetic Aperture Radar (SAR) sensors on one platform [1][2].
  • It is India's largest privately developed Earth observation satellite, at ~190 kg [1][2].
  • Contact was lost after a geomagnetic solar storm damaged an onboard system during the final stage of LEOP (Launch and Early Orbit Phase) [1].
  • Relevant for UPSC as an example of India's post-2023 New Space private-sector push under the Indian Space Policy 2023, regulated by IN-SPACe [2].

2. Why in the News

  • GalaxEye announced on Tuesday (7 July 2026) that it has lost contact with Mission Drishti following a solar-storm-induced anomaly; recovery chances are stated as "currently appears low" [1].

3. Background & Evolution

  • GalaxEye founded in 2021 by engineers from IIT Madras [2].
  • Mission Drishti launched on 3 May 2026 aboard a SpaceX Falcon 9 from Vandenberg Space Force Base, California [1][2].
  • Uses proprietary SyncFused technology to co-locate EO and SAR sensors, capturing aligned data in a single pass [2].
  • Envisaged as the first satellite of a planned constellation of 8–12 (reported elsewhere as up to 10) satellites, targeted for completion by 2029/2030 [2].
  • Anomaly occurred in the final LEOP stage, attributed by the company to radiation effects from a geomagnetic solar storm impacting a critical onboard system; communication became intermittent before being lost entirely [1].

4. Core Static Facts

Item Detail
Satellite Mission Drishti
Developer GalaxEye Space (Bengaluru start-up)
Sensor type OptoSAR — combined EO + SAR on single platform [1]
Launch date 3 May 2026 [1]
Launch vehicle SpaceX Falcon 9
Launch site Vandenberg Space Force Base, California [1]
Approx. mass ~190 kg [2]
Status (as of Jul 2026) Contact lost; recovery unlikely [1]
Governing policy framework Indian Space Policy 2023 / IN-SPACe [2]
Founded 2021, by IIT Madras engineers [2]

5. Multi-Dimensional Analysis

  • Scientific/Technological: First-ever fusion of optical and radar imaging on one commercial satellite; SAR enables all-weather, night-capable imaging while EO gives true-colour detail [1][2].
  • Economic: Signals maturing private Indian space manufacturing capability and investment in New Space start-ups; loss of the satellite is a commercial and reputational setback for GalaxEye.
  • Strategic/Administrative: Demonstrates India's growing private launch-and-build ecosystem operating under IN-SPACe authorisation, even while using a foreign (SpaceX) launch vehicle [2].
  • Governance: Anomaly highlights space-weather risk management and the need for radiation-hardening standards in India's fast-growing private satellite sector.

6. Recent Developments (last 12-18 months)

  • 3 May 2026: Mission Drishti launched via Falcon 9 from Vandenberg [1].
  • 7 July 2026: GalaxEye reports loss of contact with the satellite due to a geomagnetic-storm-related anomaly in the final LEOP stage; recovery efforts ongoing but deemed unlikely to succeed [1].

7. Prelims Hooks

  • Mission Drishti is the world's first OptoSAR satellite, combining EO and SAR sensors [1].
  • It is India's largest privately developed Earth observation satellite [1].
  • Built by GalaxEye, a Bengaluru-based space start-up founded in 2021 by IIT Madras engineers [2].
  • Launched on 3 May 2026 aboard a SpaceX Falcon 9 rocket.
  • Launch site: Vandenberg, California (not an Indian spaceport) [1].
  • Contact lost due to an anomaly following a geomagnetic solar storm during the LEOP phase [1].
  • LEOP = Launch and Early Orbit Phase.
  • Proprietary sensor-fusion technology named SyncFused [2].
  • Approx. satellite mass: ~190 kg [2].
  • Planned full constellation: 8–12 satellites, targeted by 2029 [2].
  • GalaxEye operates under India's New Space regime, governed by the Indian Space Policy 2023 and regulator IN-SPACe [2].

8. Mains Relevance

9. Related Topics to Study Next

  • Indian Space Policy 2023 — the enabling framework for private players like GalaxEye.
  • IN-SPACe — the regulator authorising private space activity in India.
  • Synthetic Aperture Radar (SAR) technology — relevant to ISRO's RISAT/EOS series.
  • Space weather / geomagnetic storms — causes and effects on satellites and infrastructure.
  • ISRO's Earth Observation Satellite (EOS) series — for comparison with private EO missions.
  • New Space economy in India — broader trend of private space start-ups (Skyroot, Agnikul, Pixxel).
  • SpaceX and commercial launch dependency — India's reliance on foreign launch vehicles for private payloads.

10. Common Errors / Trap Areas

  • Do not confuse GalaxEye (private start-up) with ISRO — Mission Drishti is privately built and funded, though enabled by government policy (IN-SPACe/Indian Space Policy 2023).
  • Do not assume Indian launch site — it was launched from Vandenberg, California via SpaceX, not from Sriharikota.
  • OptoSAR refers to sensor fusion (EO + SAR), not a single sensor type — avoid conflating it with plain SAR or plain optical imaging satellites.
  • LEOP stands for "Launch and Early Orbit Phase," not "Low Earth Orbit Phase" — a common confusion.
  • Note the loss of contact happened due to space weather (solar storm), not a launch failure — the launch itself was successful.
