ISRO’s New Earth Observation Satellite Launch: 7 Key Details You Need to Know

ISRO’s Earth Observation Satellite Launch Tomorrow: 7 Important Details

Introduction

The Indian Space Research Organisation (ISRO) is preparing to launch a new Earth observation satellite tomorrow morning. This mission will involve the Small Satellite Launch Vehicle (SSLV-D3), which will carry the EOS-08 satellite and a satellite from the startup Space Rickshaw. The launch is significant not only for ISRO but also for the future of India’s space endeavors. Below, we break down everything you need to know about this exciting mission.

The Countdown Begins

The countdown for this Earth observation satellite launch is notably short. According to ISRO officials, it will start at 2:30 AM on Friday and continue until the rocket’s launch at 9:17 AM the same day. This tight schedule reflects the mission’s importance and the precision required to ensure a successful launch.

The SSLV-D3: A Crucial Developmental Flight

The mission, named SSLV-D3/EOS-08, is the third and final developmental flight for the SSLV, a key player in ISRO’s future satellite launches. If successful, the SSLV will move from the developmental phase into full operational mode. This means it will be ready for regular missions, marking a major milestone in ISRO’s satellite launch capabilities.

What Is the Earth Observation Satellite?

The primary payload for this mission is the Earth observation satellite EOS-08, which weighs 175.5 kg and has a life expectancy of one year. This satellite is built on the Microsat/IMS-1 bus and is equipped with advanced technology designed to enhance satellite-based surveillance, environmental monitoring, and disaster management.

The SSLV Rocket: Capabilities and Technology

The SSLV is designed to launch Mini, Micro, or Nano satellites, with a mass ranging from 10 to 500 kg, into a 500 km planar orbit. The rocket’s three stages are powered by solid fuel, with a final Velocity Trimming Module (VTM) powered by liquid fuel to fine-tune the satellite’s orbit. Just 13 minutes after liftoff, the rocket will place the Earth observation satellite EOS-08 into orbit, followed by the separation of the SR-0 satellite three minutes later. Both satellites will be positioned at an altitude of 475 km.

Space Rickshaw’s First Satellite: SR-0

This mission is particularly significant for Space Rickshaw, a Chennai-based space sector startup. The SR-0 is their first satellite, marking a milestone for the company. Srimathy Kesan, Co-Founder of Space Rickshaw and CEO of Space Kidz India, shared that they plan to build six more satellites on a commercial basis, indicating a bright future for private participation in India’s space sector.

The Advanced Features of EOS-08

The Earth observation satellite EOS-08 is equipped with several cutting-edge features that will enhance its performance in various missions. The satellite carries three main payloads:

• Electro Optical Infrared Payload (EOIR): This is designed to capture images in the Mid-Wave IR (MIR) and Long-Wave IR (LWIR) bands, both day and night. This capability is crucial for applications like disaster monitoring, environmental surveillance, fire detection, and industrial safety.
• Global Navigation Satellite System-Reflectometry (GNSS-R): This payload demonstrates how GNSS-R-based remote sensing can be used for ocean surface wind analysis, soil moisture measurement, cryosphere studies, flood detection, and inland water body monitoring.
• SiC UV Dosimeter: This device monitors UV radiation at the viewport of the Crew Module in the Gaganyaan Mission. It also acts as a high-dose alarm sensor for gamma radiation, making it an essential tool for future manned space missions.

Technical Innovations in EOS-08

One of the significant advancements in the Earth observation satellite EOS-08 is its satellite mainframe system, known as the Communication, Baseband, Storage, and Positioning (CBSP) Package. This integrated avionics system combines multiple functions into a single, more efficient unit. The satellite also features a miniaturized design in its Antenna Pointing Mechanisms, capable of achieving a rotational speed of 6 degrees per second and maintaining a pointing accuracy of ±1 degree.

The Future of SSLV and ISRO’s Satellite Missions

The successful launch of this Earth observation satellite will complete the SSLV Development Project, allowing it to transition to operational missions. This shift will enable Indian industry players, particularly NewSpace India Ltd, to participate more actively in the space sector. The SSLV’s ability to launch small satellites into low Earth orbit opens up numerous possibilities for commercial, scientific, and governmental applications.

Conclusion: A Step Forward for ISRO and India’s Space Industry

As ISRO prepares to launch the Earth observation satellite tomorrow, the success of this mission could significantly impact India’s space exploration capabilities. The development and operationalization of the SSLV will provide a reliable platform for launching small satellites, benefiting various sectors. The innovations in EOS-08, such as its advanced payloads and integrated avionics, demonstrate ISRO’s commitment to pushing the boundaries of space technology. This launch marks another step forward in India’s growing role in the global space community, setting the stage for future missions and partnerships.
