The astronauts' principal interest should be to substitute the out dated high resolution spectrograph and a cam with a couple of instruments mat kinh hang hieu constructed by Ball Aerospace in Broomfield

Astronauts in space cab Detection are intending this morning mat kinh thoi trang to snag the Hubble Space Telescope for a tuneup and key apparatus transforms.
The modernization consists substituting two instruments with new ones which were produced in Colorado. It won't come cost efficient; NASA approximates the whole of the refurbishment 're going to cost $795 mil, consisting of launch costs.
Because NASA's Hubble fix task in 1993, the telescope has supplied an empty, profound view into far attains of space. It has relayed spectacular shots, consisting of photos mat kinh thoi trang of clouds of hydrogen, dust billowing for trillions of miles and glimpses of galaxies colliding at 1 mil mph.
The effects have revolutionized presumptions to the birth of the galaxy and star development.
That begs the question, if Hubble is not damaged anymore, why jeopardy messing around with it?
Astronomers mentioned Mon which snagging the telescope is actually a perilous technique which may backfire. The observatory was modeled within the Nineteen Seventies and the various tools timetabled for alternative are out dated. Quite a few components are sick, too.
``If we were to depart it solitary, the danger of not doing anything will be finer,'' mentioned Ted Snow, a College of Colorado astronomer and chairman of the Hubble Users Team, the multinational science advisory body.
The Hubble Space Telescope was modeled for tuneups in orbit. Still, it will not be a simple career.
Astronauts have been coaching maritime for 24 months to mimic doing work in microgravity.
They should grasp the faculty bus-sized satellite with the shuttle's robot arm, drag it inside the shipment bay and latch it to a platform.
The fresh instruments are suited into chests as big as telephone booths. They slide into compartments at the telescope's base really love drawers in a cabinet; each apparatus suits with 1 / 4 clearance.
``We can't pay up an error,'' mentioned NASA project manager Frank Cepollina. ``We cannot leave this automobile worse off than it was before we got to it.''

The fresh $125 mil imagining spectrograph 're going to do the duty of the old instruments, plus mat kinh hang hieu more. From the space object's ultraviolet light signature, research workers could determine a star's matchless composition, heat level and movements.
The fresh spectrograph operates 40 times speedier and A hundred times more effectively than old instruments, mentioned Ball program manager John Hetlinger. Source
The 2nd new apparatus, a $One hundred and five mil near-infrared cam, 're going to use wide-angle and telephoto lenses to fellow through dust clouds in space - what astronomers call ``star nurseries.'' Astronomers wish to record the birth of actresses and photo voltaic systems.
