Hubble telescope beloved by astronomers
Published in Saudi Press Agency on 08 - 06 - 2007


The Hubble space telescope, which has glimpsed
billions of years back in time to the early days of galaxies, got a
new lease on life last October when NASA decided to include a service
mission in its hectic schedule, according to dpa.
NASA officials confirmed Friday the mission date would be
September 11, 2008.
The decision took 18 months and extensive study of safety issues,
NASA director Michael Griffin said at the time. His announcement
triggered a half a minute of applause from workers at the Godddard
Space Centre in Maryland that operates Hubble.
Without servicing, Hubble could lose its ability to take pictures
of galaxy formations and boiling star nebulae by next year,
scientists said. A repair mission slated for 2004 was cancelled under
pressure for the aging shuttles to return to flight and finish
construction on the International Space Station before the heavy-
lifting aircraft are retired in 2010.
The 2003 Columbia shuttle disaster made planning for a repair
mission even more difficult, as NASA has spent the past two years
launching test flights in its cautious return to space. The success
of the test flights confinced Griffin and NASA to add a Hubble repair
flight to the schedule.
The prospect that Hubble would die in space alarmed international
scientists and worried school teachers who use internet photographs
from outer space - quasars and black holes and galaxy formations - to
inspire their students. NASA investigated, then dropped, the idea of
sending a robot to do the repairs.
The Hubble mission will have to carry out at least four or five
space walks to service the telescope, and be prepared to make extra
walks to repair any damages to the shuttle that occurs on takeoff.
Missions to the space station are easier because ISS crew is on
hand to help inspect the shuttle. The ISS also offers up to three
months refuge for visiting crew in case of an emergency.
The Hubble, which orbits 580 kilometres above Earth, offers
neither. That means the shuttle would have to survive on its own for
up to 25 days, with the second shuttle on stand-by at a separate
launch pad for a rescue mission.
After years in planning, the 1.55-billion-dollar space telescope
was released from a shuttle in 1990, only to find its vision blurred
by small error one-fiftieth of the width of a human hair in its lens.
It produced blurry images barely better than those seen through
Earth's cloudy atmosphere.
"Word came back that Hubble couldn't see and it needed the most
expensive contact lens in world history," recalled Senator Barbara
Mikulski, a powerful Democrat and one of NASA's biggest boosters.
After the repair, Hubble became one of the most scientifically
productive spacecraft ever launched, peering 2.2 billion light years
away into the Abell 1689 galaxy, recording the minus-270-degree-
celsius-background glow from the Big Bang and producing jaw-dropping
images of swirling clouds of space matter in oranges, greens,
yellows, reds - the Crab Nebula, the starburst Galaxy Messier 82.
NASA's decision to scrap the Hubble provoked protests in the
scientific community, especially after US President George W Bush
decided to divert NASA money into a 12-billion-dollar new moon
programme over five years.
The space community took little consolation that Hubble's
replacement, the James Webb Space Telescope, is slated for launch in
2013. That would still have left them with a three or four
year gap with no window on the universe.
With the new mission, Hubble can last at least until 2013.
