Isro gearing upto launch SSLV, its new-gen mini rocket launch system

The Indian Space Research Organisation (Isro) is all set to add another feather in its cap, as it gets ready to launch a new-generation compact rocket on its maiden orbital test flight.

So far, Isro has developed five generation of launch vehicles — SLV-3, ASLV, PSLV, GSLV and GSLV-MkIII.

It started working on developing a new launch vehicle of mini rockets – Small Satellite Launch Vehicle (SSLV) – to meet needs of the emerging global small satellite launch service market.

In a report, news agency PTI said several sources in Isro have said that SSLV-D1 is targeted to be launched towards the end of March or early April. However, there is no official confirmation on the date so far.

“We are flying an earth observation satellite (EOS-02) on board the first development flight of SSLV,” Isro Chairman and Secretary in the Department of Space, K Sivan was quoted as saying by PTI.

Reports suggest that SSLV has been designed to meet “launch on-demand” requirements in a cost-effective manner for small satellites in a dedicated and rideshare mode.

SSLV is a three-stage all solid vehicle and has the capability to launch up to 500 kg satellite mass into 500 km low earth orbit (LEO) and 300 kg to Sun Synchronous Orbit (SSO).

“By comparison, PSLV — the workhorse of ISRO — can take up to 1,750 kg payload into SSO of 600 km altitude,” PTI reported quoting Isro sources.

Apart from the capability to launch upto 500kg of satellite mass, the SSLV will have the option of multiple satellite mounting options for nano, micro and small satellites.

In the past, Isro chief Sivan had said SSLV would be an innovative vehicle that can be assembled in just 72 hours.

“Instead of 60 days (for building a PSLV), it (SSLV) will be assembled in three days; instead of 600 people (needed to build a PSLV), it (SSLV) will be done by six people”, he had told PTI
