spacecraft

is

traveling

to

Mars

to

collect

information

about

the

red

planet.

The

Mars

Reconnaissance

Orbiter

left

Cape

Canaveral

in

Florida

on

August

12th.

The

space

vehicle

is

expected

to

arrive

in

The

U.S.

space

shuttle

Columbia

has

returned

to

Earth

after

an

abbreviated

stay

in

space

because

of

a

mechanical

problem.

The

Space

Agency

ordered

the

shuttle

back

to

Earth

after

one

of

the

three

power

generators

failed

Sunday.

The

generators

called

“fuel

cells”

provide

all

of

shuttle’s

electrical

power,

and

NASA

safety

rules

require

the

space

ship

to

return

to

Earth

if

any

fuel

cell

fails.

US

space

shuttle

Discovery

has

made

a

successful

lift-off

from

Kennedy

Space

in

Florida,

en

route

to

the

International

Space

Station.

The

shuttle

with

5

male

and

2

female

astronauts

onboard

will

take

another

section

of

the

half-built

International

Space

Station

a

little

truss,

or

frame

into

orbits.

It’s

scheduled

to

come

back

to

earth

on

December

21.

United

States

Space

Agency

NASA

says

it's

given

up

any

real

hope

of

reviving

its

space

on

Mars.

The

spacecraft

Pathfinder

made

its

last

transmission

of

scientific

data

from

the

surface

of

Mars

at

the

end

of

September,

83

days

after

landing.
