Projects: Save Voyager and Hubble
Hubble -- The People's Telescope

Hubble Space Telescope
The name itself encourages familiarity: the Hubble Space Telescope -- in documents
reduced to its NASA acronym, HST -- in popular parlance was inevitably
shortened to just "Hubble" -- a friendly, easy-to-remember name. Here

By now you've heard the news: NASA Administrator Mike Griffin has decided
to send the space shuttle Discovery to repair the Hubble Space Telescope,
reversing a decision made by his predecessor, Sean O'Keefe.
This is a tremendous victory for Planetary Society members -- and for
the millions around the world who rose up in protest at the unbelievable
decision to let Hubble die. Some 10,000 Planetary Society members focused
their efforts in a petition campaign directed at the U.S. Congress, which
controls NASA's purse-strings. Congress listened to us. And NASA listened
to Congress.
Now that we have won the battle, it's perhaps useful to take a moment
to consider how the miscalculation to let Hubble die could have been made.
I believe it's because administration managers did not understand that
-- as scientific success followed engineering triumph, and image after
image brought home the beauty and sheer magnificence of space -- Hubble
had become more than an orbiting scientific instrument.
Hubble became the people's telescope -- surprising NASA managers who perhaps
underestimated the passion generated by those magnificent images of the
cosmos. The astounding images captured by Hubble made the unfathomable
depths of space accessible as had no other telescope in history. People
came to feel a personal connection with this scientific instrument of metal
and glass. They refused to let it die.
Here is the measure of their devotion: It will cost $900 million to repair
Hubble, AND is the people have made clear that is a price they are willing
to pay. Even though it is 16 years old, they see Hubble as an asset for the
future. NASA and the politicians now know the public feels that repairing
Hubble is worth the money -- and worth the risk of a shuttle flight.
And so, in early May 2008, the shuttle discovery will rendezvous with Hubble
and attempt the repairs that could keep it alive and teaching us more about
the wonders of the universe.
You made that possible. You and your fellow Planetary Society members made
your voices heard. You and millions around the world changed a government
bureaucracy and got the result the future will thank you for. Congratulations.
But in our elation over Hubble, let's not forget Voyager.
The Planetary Society campaigned not just to save Hubble, but also to save
the Voyager spacecraft now probing the edges of our solar system. As part
of another wave of budget-cutting, NASA planned to shut down operations just
as the spacecraft were approaching the heliopause, the boundary with interstellar
space.
The patent absurdity of that move made it easier to counter than the decision
to cancel the repair mission to Hubble, which involved the risk of human life
following the loss of the shuttle Columbia.
The move to shut down Voyager was simply over-zealous bean-counting. When
the ramifications of turning off two of the most successful robotic explorers
in history were rammed home, the proposal was allowed to evaporate.
At the edge of the solar system, Voyagers 1 and 2 will continue to explore
the unknown until around 2020, when their nuclear batteries will run down.
By then, we will be ready to say "well done" and let them go. Even
without power, they will continue to voyage outward, each carrying a gold
record, created by Planetary Society co-founder Carl Sagan and friends, that
is a message from the people of Earth to whomever or whatever might someday
find these emissaries somewhere among the stars.
Whew! Hubble and Voyager saved. It's been a good day's work. Thank you.
