SSLV-D1 Lift-Off
First I will try to explain the Mission objectives then I will explain that why this mission failed. I will request you to keep reading till last word to get the idea
You're quite wondering what is SSLV. Meanwhile, you're also appreciating India for its advancement in the field of science and technology.
So without wasting our time we move toward that what is SSLV?
SSLV stands for Small Satellite Launch Vehicle. The Small Satellite Launch Vehicle (SSLV) is a small-lift launch vehicle developed by the Indian Space Research Organisation (ISRO) with payload capacity to deliver 500 kg (1,100 lb) to low Earth orbit (500 km (310 mi)) or 300 kg (660 lb) to Sun-synchronous orbit (500 km (310 mi)) for launching small satellites, with the capability to support multiple orbital drop-offs.] SSLV is made keeping low cost, low turnaround time in mind with launch-on-demand flexibility under minimal infrastructure requirements.
EOS-02 and "AzaadiSAT," an 8 kilogramme CubeSat created by 750 female students from government schools in India, are manifested by SSLV-D1.
The Small Satellite Launch Vehicle (SSLV) is a new launch vehicle from ISRO that can send Mini, Micro, or Nanosatellites (10 to 500 kg in mass) into an orbit 500 km in the upper atmosphere. All three stages of the SSLV's three-stage design include solid propulsion. A liquid-based Velocity Trimming Module is used to propel the satellite into its intended orbit (VTM).
What is EOS-02?
Salient Features of EOS-02
- A flexible and experimental satellite with an imaging payload is what EOS-02 is designed to be.
- Supplying information on thermal anomalies to support applications for forestry, hydrology, agriculture, soil, coastal studies, and other geoenvironmental studies.
EOS-02 configuration
- The structure's framework is made of aluminium honeycomb. A 552 mm x 600 mm x 600 mm cuboid structure is intended and qualified for a 145 kg total spacecraft mass.
- Subsystems for the mainframe/Bus are integrated, separate payloads. The top deck has space for the entire payload.
- The only deployable appendages are the two solar panels, each of which can produce 350 W of power.
- The platform has a pointing precision of 0.1 and a mobility of 3.5°/s.
- In X-Band, the payload data transmission rate is 32 Mbps.

Features of SSLV-D1
- To save segment assembly and launch integration time, the booster motor segment has an open joint configuration.
- Pyro systems can be started directly using a shortened Pyro circuit.
- Modular separation hardware and software for quick turnaround and easy production.
- unified configuration of the interstage joints to facilitate rapid integration and launch. Multi Satellite Adaptor (MSA) deck for multi-satellite accommodations.
- Low-cost, industrial COTS avionics systems that have been downsized.
- Integrated inertial navigation system for the NaviC that is affordable and has a control-class MEMS sensor allows for assisted navigation throughout the flight regime. a totally indigenous digital control system with electromechanical actuators.
- With a minimal number of ground connectors, the onboard checkout computer has a straightforward and quickly reconfigurable checkout system.

Failure
Issuing a statement on the SSLV-D1/EOS-02 mission update, ISRO said, “All stages performed normally. Both satellites were injected. But the orbit achieved was less than expected which makes it unstable.”
