ISRO's SSLV-D2 successfully launched

The Indian Space Research Organization (ISRO) will conduct the Small Satellite Launch Vehicle’s second development flight (SSLV –D2).

The SSLV-D2 is designed to deliver ISRO’s EOS-07, Antaris’ Janus-1, and Chennai-based Space Kidz’s AzaadiSAT-2 satellites into a 450-km circular orbit in 15 minutes.
ISRO designed, developed, and launched EOS-07, a 156.3 kg satellite. Its mission is to design and develop payload instruments that are compatible with microsatellite buses and new technologies for future operational satellites.
Janus-1: Janus-1, weighing approximately 10.2 kg, is a technology demonstrator, smart satellite mission based on the Antaris software platform.
AzaadiSAT-2: An 8.7-kg satellite, AzaadiSAT-2 is a collaborative effort of approximately 750 girl students from across India, led by Space Kidz India in Chennai.

The SSLV is an ISRO-developed small-lift launch vehicle with payload capacity of 600 kg to Low Earth Orbit (500 km) or 300 kg to Sun-synchronous Orbit (500 km)
It would aid in the launch of small satellites capable of multiple orbital drop-offs.
A dedicated launch pad called the Small Satellite Launch Complex (SSLC) will be built in Sriharikota in the future.
When completed, a new spaceport near Kulasekharapatnam in Tamil Nadu will handle SSLV launches.
After entering the operational phase, the vehicle’s production and launch operations will be handled by an Indian consortium led by NewSpace India Limited (NSIL).

The vehicle will launch in four stages.
The first three stages will use a solid propellant based on hydroxyl-terminated polybutadiene (HTPB), with a fourth terminal stage being a Velocity-Trimming Module (VTM).

The SSLV was developed with the aim of launching small satellites commercially at drastically reduced price and higher launch rate as compared to Polar SLV (PSLV).
The projected high launch rate is based on largely autonomous launch operations and simple logistics in general.
In comparison, a PSLV launch involves 600 officials, whereas SSLV launch operations are managed by a small team of around six people.
The SSLV’s launch readiness period is expected to be less than a week rather than months.
The SSLV can launch satellites weighing up to 500 kg into low-Earth orbit, whereas the tried-and-true PSLV can launch satellites weighing up to 1000 kg.
The entire project will be completed in a very short period of time, and the cost for SSLV will be around Rs 30 crore.

SSLV is ideal for simultaneously launching multiple microsatellites and supports multiple orbital drop-offs.
The SSLV’s development and production are expected to increase synergy between the space sector and private Indian industries, which is a key goal of the space ministry.
