Context:
ISRO commenced the countdown for the PSLV-C62/EOS-N1 Mission, marking the 105th launch from Sriharikota and the 64th flight of PSLV, including international satellite collaborations.
Key Highlights:
- Mission Overview
- Launch Vehicle: PSLV-DL variant (fifth mission of this configuration).
- Payload: EOS-N1 (primary satellite) + 15 co-passenger satellites.
- Launch Site: Satish Dhawan Space Centre (SDSC), Sriharikota.
- Commercial mission executed by NewSpace India Limited (NSIL).
- Primary Payload – EOS-N1
- Intended for strategic and earth observation purposes.
- Injected into a Sun Synchronous Orbit (SSO).
- Co-Passenger Satellites
- Developed by Indian startups, academic institutions, and international partners.
- International participation from Thailand, U.K., Nepal, Spain, France, Brazil, etc.
- Reflects India’s expanding role in the global small satellite market.
- Technical Features
- Post-deployment, PS4 stage restart for de-boost and controlled re-entry.
- Separation of KID Capsule, both impacting the South Pacific Ocean.
- Significance
- Strengthens India’s commercial space footprint.
- Encourages private sector participation under space sector reforms.
- Boosts international collaboration in space technology.
