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 [S1][S2].
It is India's largest privately developed Earth observation satellite, at ~190 kg [S1][S2].
Contact was lost after a geomagnetic solar storm damaged an onboard system during the final stage of LEOP (Launch and Early Orbit Phase) [S1].
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 [S2].

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" [S1].

GalaxEye founded in 2021 by engineers from IIT Madras [S2].
Mission Drishti launched on 3 May 2026 aboard a SpaceX Falcon 9 from Vandenberg Space Force Base, California [S1][S2].
Uses proprietary SyncFused technology to co-locate EO and SAR sensors, capturing aligned data in a single pass [S2].
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 [S2].
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 [S1].

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 [S1][S2].
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 [S2].
Governance: Anomaly highlights space-weather risk management and the need for radiation-hardening standards in India's fast-growing private satellite sector.

3 May 2026: Mission Drishti launched via Falcon 9 from Vandenberg [S1].
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 [S1].

Mission Drishti is the world's first OptoSAR satellite, combining EO and SAR sensors [S1].
It is India's largest privately developed Earth observation satellite [S1].
Built by GalaxEye, a Bengaluru-based space start-up founded in 2021 by IIT Madras engineers [S2].
Launched on 3 May 2026 aboard a SpaceX Falcon 9 rocket.
Launch site: Vandenberg, California (not an Indian spaceport) [S1].
Contact lost due to an anomaly following a geomagnetic solar storm during the LEOP phase [S1].
LEOP = Launch and Early Orbit Phase.
Proprietary sensor-fusion technology named SyncFused [S2].
Approx. satellite mass: ~190 kg [S2].
Planned full constellation: 8–12 satellites, targeted by 2029 [S2].
GalaxEye operates under India's New Space regime, governed by the Indian Space Policy 2023 and regulator IN-SPACe [S2].

GS-III: Science & Technology — indigenization of technology; Space sector reforms and private participation.
GS-II (peripheral): Governance of emerging sectors — regulatory frameworks (IN-SPACe, Indian Space Policy 2023).
Possible question stems:
"Discuss the significance of private participation in India's space sector post the Indian Space Policy, 2023, with reference to recent satellite missions." (GS-III)
"What are the risks posed by space weather events to satellite operations? Suggest measures for resilience." (GS-III)
"Examine the role of start-ups in building India's sovereign Earth observation capacity." (GS-III)

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.

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.
