HOUSTON -- Crews at NASA are gearing up to test one of the two largest vacuum chambers in the world.
The next generation, deep space telescope will be tested at Johnson Space Center starting next year.
One NASA manager says they have just one chance to get it right in the simulated space environment.
"We're not going to go there and service it. We're not going to go and be able to repair it. It's got to work when it leaves the Earth and it's got to work when it gets up there. We have to do lot's of ground testing to insure that," said NASA manager Mary Cerimele.
The telescope will be launched a million miles from earth, four times farther than the moon.
NASA hopes it will see more than Hubble ever has.
