The U.S. space shuttle Atlantis has lifed off for an ambitious repair
mission to the Hubble Space Telescope. The U.S. space agency hopes the
complicated and expensive mission will extend Hubble's life over many
years.

During the 11-day mission, Atlantis' astronauts will make five space
walks. They will replace batteries, gyroscopes and cameras that have
been in operation since the orbiting telescope was launched 19 years
ago.
NASA Science Mission Directorate associate administrator Ed Weiler says
Hubble has lasted much lasted longer than anyone expected.
"Considering we launched Hubble in 1990 with a hopeful lifetime of 10 to
15 years, and if we do last the 5 years we expect, we will be entering
our second quarter century on Hubble," Weiler said. "That is not bad on
a mission that we hoped would last 10 to 15 years."
In its nearly two decades, Hubble has conducted vast amounts of
astronomical research, including the discovery that the universe is
expanding at a faster and faster rate. The space telescope has also
collected data suggesting that galaxies were formed shortly after the
Big Bang explosion that created the universe 13.7 billion years ago.
Hubble
has returned spectacular views of the cosmos. Weiler and other space
officials hope with new cameras, Hubble will be able to peer still
deeper into the Universe in the coming years.
"Hubble has become a standard of excellence in our society," he said. As
I said, it is the standard in every new astronomy textbook, whether it
is published in English, Spanish, Chinese, [and] Arabic whatever. The
images of the Hubble appear in newspaper, magazines, the internet,
museums, even art galleries around the world."
NASA has put the cost of the repair mission at $1 billion.
Space officials say thousands of people gathered under sunny skies to
watch the launch of Atlantis at the Kennedy Space Flight Center in
Florida. |
