Bengaluru, Feb 25 (PTI) The Indian Space Research
Organisation (ISRO) is getting ready to launch a new-
generation compact rocket on its maiden orbital test flight,
the space agency said.
Bengaluru-headquartered ISRO has over the years realised
five generation of launch vehicles -- SLV-3, ASLV, PSLV, GSLV
It had taken up development of the mini rocket -- Small
Satellite Launch Vehicle (SSLV) -- to cater to emerging global
small satellite launch service market.
Multiple sources in ISRO said on Thursday SSLV-D1 is
targeted to be launched towards the end of March or early
April -- most likely in the first month of the financial year
-- though no firm date has been set so far.
"We are flying an earth observation satellite (EOS-02) on
board the the first development flight of SSLV", ISRO Chairman
and Secretary in the Department of Space, K Sivan told PTI.
SSLV has been designed to meet "launch on demand"
requirements in a cost-effective manner for small satellites
in a dedicated and rideshare mode.
It is a three-stage all solid vehicle with a 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, according
to ISRO officials.
With lower per kg launch cost, the mini launcher will
have multiple satellite mounting options for nano, micro and
Sivan had earlier termed the SSLV an innovative vehicle
which 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
Chairman and Managing Director of ISRO''s commercial arm,
NewSpace India Limited (NSIL), G Narayanan said: "world over
there is a big boom for small launch vehicles and that''s why
we are focusing on that".
"As soon as SSLV-D1flight is over successfully, further
roadmap (for SSLV) will be charted out", Narayanan told PTI.
In fact, Seattle, US-based satellite rideshare and
mission management provider, Spaceflight Inc., has already
purchased the first commercial launch of the SSLV (SSLV-D2)
from NSIL for launch from the Satish Dhawan Space Centre in
Spaceflight had said at the time that it has already
sold-out the entire manifest (launch) for this secured SSLV-D2
launch, with spacecraft from an undisclosed U.S.-based
satellite constellation customer.
This undisclosed customer is reportedly Seattle-based
BlackSky Global which will launch four earth observation
satellites on board SSLV-D2 in the rideshare mission arranged
"We''re taking advantage of the growth in the small
satellite market to deliver more launch options with the
mini-launcher", a senior NSIL official said.
"The SSLV is the much-needed solution to fill the gap in
the portfolio of small launch vehicles," CEO and President of
Spaceflight, Curt Blake, had said.
"SSLV is designed for the launch-on-demand concept with
very quick turn-around capability in between launches. SSLV is
perfectly suited for launching multiple microsatellites at a
time and supports multiple orbital drop-offs", Blake had said.
