The Indian Space Research Organisation (ISRO) has improved its impressive space technology by successfully launch of its Polar Satellite Launch Vehicle, i.e., PSLV-C56, from Sriharikota, Andhra Pradesh.PSLV-C56’s launch with seven satellites, including DS-SAR, is a significant milestone for India’s space efforts and global cooperation in space research.
DS-SAR Satellite: A Breakthrough in Collaboration
The primary payload of PSLV-C56 is the DS-SAR satellite, a joint venture between Singapore’s government Defence Science and Technology Agency (DSTA and ST Engineering. The DS-SAR satellite weighs 360 kg and features an advanced Synthetic-aperture radar (SAR) from Israel Aerospace Industries (IAI). This radar provides all-weather, day, and night coverage with exceptional 1-meter resolution at full polarimetry.
The high-resolution SAR payload allows the Singapore government to assess natural disaster damage, monitor land use, track deforestation, and efficiently support security and defense operations. The satellite’s applications also cater to commercial customers for tasks like oil and gas exploration, agriculture monitoring, and infrastructure assessment.
Near-equatorial Orbit (NEO) Deployment
The DS-SAR satellite was launched into a Near-equatorial Orbit (NEO) at 535 km altitude, perfectly meeting the imagery needs of Singapore government agencies and ST Engineering’s commercial clients. The NEO deployment optimizes the satellite’s capabilities for intended purposes, making it more effective in meeting the diverse needs of users.
Co-Passenger Satellites: Showcasing India’s Space Expertise
In addition to DS-SAR, PSLV-C56 carried six co-passenger satellites, highlighting India’s space technology expertise and promoting international collaborations in space research.
- VELOX-AM: This microsatellite is designed for technology demonstration.
- ARCADE: This experimental satellite is dedicated to exploring atmospheric coupling and dynamics.
- SCOOB-II: This nanosatellite carries a technology demonstrator payload.
- NuLIoN by NuSpace: This advanced technology nanosatellite ensures smooth IoT connectivity in cities and remote areas.
- Galassia-2: This nanosatellite is situated in low earth orbit.
- ORB-12 STRIDER: Global cooperation led to the development of this satellite.
Emphasizing Responsible Space Practices
After deploying all satellites, the upper stage of PSLV-C56 will be maneuvered to a lower orbit, showcasing ISRO’s commitment to responsible space practices. By minimizing the upper stage’s orbital life, ISRO aims to contribute to space sustainability and reduce potential hazards from space debris.
The successful launch of PSLV-C56 with DS-SAR satellite and co-passenger payloads is a significant achievement for ISRO and India’s space exploration efforts. This achievement showcases India’s space technology capabilities and emphasizes the importance of international cooperation in advancing space research.
Collaborative missions like PSLV-C56 promise to expand our knowledge of the cosmos and its wonders as we continue to explore and push the boundaries of space technology. ISRO and its international partners use advanced satellite technology to address global challenges, monitor Earth, and support diverse applications for governments and industries worldwide.
