India is gearing up for another spectacular space mission on July 30, 2023, when it will launch seven Singaporean satellites using its Polar Satellite Launch Vehicle (PSLV). This will be the PSLV’s second mission this year and the 90th space mission of the Indian Space Research Organisation (ISRO).

What are the satellites and why are they important?

🛰️The main satellite of the PSLV-C56 mission is the DS-SAR, a 360-kg satellite developed by Singapore’s Defence Science and Technology Agency (DSTA) and ST Engineering. DS-SAR stands for Dual-Sided Synthetic Aperture Radar, which is a type of radar that can produce high-resolution images of the Earth’s surface under all weather conditions and at any time of the day or night.

🚀DS-SAR will be used to support the satellite imagery needs of various agencies within the Government of Singapore, as well as for commercial purposes by ST Engineering. The satellite will also demonstrate the capabilities of Singapore’s space industry and foster collaboration with other countries.

📌The six co-passenger satellites are:

VELOX-AM, a technology demonstration microsatellite that will test a new attitude control system and a novel propulsion system.
ARCADE, an experimental satellite that will study the effects of atmospheric coupling and dynamics on radio signals.
SCOOB-II, a 3U nanosatellite that will fly a technology demonstrator payload for space situational awareness.
NuLIoN by NuSpace, an advanced 3U nanosatellite that will enable seamless IoT connectivity in both urban and remote locations.
Galassia-2, a 3U nanosatellite that will orbit at low earth orbit and test various subsystems and payloads.
ORB-12 STRIDER, a satellite developed under an international collaboration that will demonstrate a new propulsion system and a novel deployable structure.

🛰️These satellites will showcase the diversity and innovation of Singapore’s space sector and provide valuable data and services for various applications.

How will the launch take place?

🚀The launch will take place from the first launchpad at ISRO’s Sriharikota spaceport in Andhra Pradesh at 6.30 am IST. The PSLV-C56 will be configured in its core-alone mode, which means it will not have any strap-on boosters. This mode is suitable for launching lighter satellites into low earth orbit.

🛰️The PSLV-C56 will inject the DS-SAR satellite into a sun-synchronous orbit at an altitude of about 500 km and an inclination of 97.5 degrees. The co-passenger satellites will be released into different orbits according to their requirements.

🛰️The launch has been procured by NewSpace India Limited (NSIL), a central public sector undertaking under the Department of Space, which is responsible for marketing ISRO’s products and services. NSIL has signed a contract with DSTA and ST Engineering to deploy the DS-SAR satellite using the PSLV-C56.

Benefits and Challenges of this mission

❇️This mission will strengthen India’s position as a reliable and cost-effective launch service provider for small satellites. It will also enhance India’s cooperation with Singapore in the field of space technology and applications. The mission will also contribute to ISRO’s vision of harnessing space for national development and global welfare.

😒However, the mission also faces some challenges, such as ensuring the safety and security of the satellites during launch and orbit operations, as well as complying with international norms and regulations regarding space activities. Moreover, the mission will have to deal with the uncertainties and risks associated with space exploration, such as weather conditions, technical glitches, and orbital debris.

Conclusion

India’s PSLV-C56 mission is an exciting and ambitious endeavor that will showcase the capabilities and achievements of both India and Singapore in the domain of space. The mission will also demonstrate the potential and benefits of collaboration and innovation in advancing humanity’s exploration and utilization of space.
