The
exploration
of
Mars
has
been
an
important
part
of
the
space
exploration
programs
of
Russia,
the
United
States,
Europe,
and
Japan.
Dozens
of
robotic
spacecraft,
including
orbiters,
landers,
and
rovers,
have
been
launched
toward
Mars
since
the
1960s.
These
missions
were
aimed
at
gathering
data
about
current
conditions
and
answering
questions
about
the
history
of
Mars.
The
questions
are
expected
to
not
only
give
a
better
appreciation
of
the
red
planet
but
also
yield
further
insight
into
the
past,
and
possible
future,
of
Earth.

What
is
the
main
aim
of
the
plan?
To
transform
Mars
so
that
people
can
live
there.

2.
The
programme
of
transform
Mars
involves
four
main
stages.
3.
At
the
stage
1,
if
people
wear
spacesuits,
they
can
survive.
4.
The
thicker
of
the
atmosphere
in
Mars
is,
the
more
of
the
Sun's
heat
can
be
kept.
5.
At
the
stage
4,
plants
are
introduced
from
earth.
6.
At
the
last
stage,
the
people
living
in
Mars
can
go
outside
without

Space
research
is
an
extremely
costly
research
programme.
Although
space
research
extends
knowledge
beyond
the
planet
earth
and
satisfies
our
curiosity
about
the
mystery
of
the
universe,
is
it
worth
investing
the
money
and
resources
in
space
exploration
programmes
when
we
already
have
many
problems
to
be
solved
on
the
earth?

What
are
the
benefits
of
space
exploration?
The
advances
made
