New
Delhi,
Aug
07:
Two
satellites
that
were
onboard
the
first
flight
of
a
new
Indian
Space
Research
Organisation
(ISRO)
rocket
got
placed
in
an
unstable
orbit
and
are
no
longer
usable,
said
the
space
agency.

The
space
agency
said
a
committee
would
analyse
and
make
recommendations
into
today’s
episode
and
with
the
implementation
of
those
recommendations
“ISRO
will
come
back
soon
with
SSLV-D2.”

“SSLV-D1
placed
the
satellites
into
356
km
x
76
km
elliptical
orbit
instead
of
356
km
circular
orbit.
Satellites
are
no
longer
usable.
Issue
is
reasonably
identified.
Failure
of
a
logic
to
identify
a
sensor
failure
and
go
for
a
salvage
action
caused
the
deviation,”
ISRO
said
in
an
update
on
its
official
Twitter
handle.
