Scientists
preparing
for
NASA's
proposed
Jupiter
Icy
Moons
Orbiter
believe
that
Jupiter's
moons
Europa
may
be
a
____________________
mixture
of
acid
and
peroxide
.
Thus
,
it
____________________
not
be
the
____________________
place
for
life
to
exist
as
was
thought
possibly
to
be
the
case
.
____________________
all
the
information
we
have
about
Europa
comes
from
the
spacecraft
Galileo
,
which
completed
its
mission
to
study
Jupiter
and
its
moons
close
up
before
NASA
dramatically
crashed
it
into
Jupiter
in
2003
.
____________________
the
general
perception
of
Europa
is
of
a
frozen

of
water
ice
harboring
a
salty

ocean
kilometers
below
,
researchers
studying
the
most

measurements
say
light
reflected
from
the
moon's
icy
surface
bears
the
____________________
fingerprints
of
hydrogen
peroxide
and
strong
acids
.

they
accept
that
it
could
just
be
a
thin
surface
dusting
and
might
not
come
