Servicing Missions to the Hubble Space Telescope
Author: Jeremy Hier

The Hubble Space Telescope received its first Service Mission in December 1993. The missions most important objective was to install two devices to fix the Hubble Telescope's vision problem . The space telescope could not focus all the light from an object to a single sharp point because Hubble's primary mirror was incorrectly shaped. Instead it saw a fuzzy halo around objects it observed in space.

Interesting facts about Hubble Space Telescope is there is no question that the Hubble Telescope gave us amazing pictures and views of very early distant galaxies. But because the universe is expanding, the light from the most distant space galaxies is shifted to infrared wavelengths. So to see the galaxies the Hubble neede to be fitted with an instrument that could observe infrared light.

In Feb. 1997 the Hubble Telescope received its Second Servicing Mission. The space shuttle Discovery was boarded by seven astronauts. They installed two technologically advanced instruments, onto the Hubble. To observe space objects in infrared wavelengths the Near Infrared Camera and Multi-Object Spectrometer was installed. The second instrument installed was the Space Telescope Imaging Spectrograph, which is used to take detailed pictures of celestial objects and hunt for black holes.

Service Mission 3A in December 1999 was a busy one for the space telescope. Their goal was the replacement of gyroscopes, which accurately point the Hubble at celestial targets. The crew replaced all six gyroscopes as well as one of Hubble's three fine guidance sensors, which allow fine pointing and keep Hubble stable during space observations.

Service Mission B for the Hubble Telescope occurred on March 1st 2002 when NASA launched the space shuttle Columbia, where its seven member crew met with Hubble to perform a series of upgrades. The astronauts performed five spacewalks. Their mission was to install the Advanced Camera for Surveys. The ACS doubled Hubble's field of view and collects data ten times faster than before.

Exploring the Universe with Dr. Norio Kaifu
Author: Gayle Olson
During 1998 we were fortunate to attend a dinner hosted by the Japanese Chamber of Commerce and Industry of Hawaii, featuring a lecture by Dr. Norio Kaifu. Professor Kaifu is the director of the Subaru Telescope, National Astronomical Observatory of Japan (NAOJ) and has held the position as vice president of the International Astronomical Union (IAU) since 1997. A specialist in radio astronomy, infrared astronomy and interstellar matter, Dr. Kaifu has published some 100 papers on astronomy in addition to 15 popular science books. Before joining the Subaru in 1990, he was a director, a professor and an associate professor at the Nobeyama Radio Observatory, and a senior research associate in the Faculty of Science at the University of Tokyo. As an amateur backyard astronomer we were delighted to learn of the possibilities this new telescope will bring to the exploration of universal knowledge.

Dr. Kaifu shared his views about the design of the new telescope, cylindrical in shape, rather than dome, it can be more optimal for wind resistance. The 8-meter diameter glass mirror is only 8 inches thick and has taken six years to construct and polish. The mirror is controlled by two Fujitsu parallel computers, with the largest memory capacity in the world with 261 supporting structures. 100 times per second the computer adjusts the mirror to counteract the atmospheric turbulence, which we see as twinkling stars. The mirror can be controlled by the computer by each second, to obtain the best view of the deeper universe. Mauna Kea was chosen as a location for the new Japanese telescope because of the stable weather and easy access.

What will the new telescope discover? Astronomer's will be using the telescope to study the history of our galaxy and answer questions as to how life was created in the universe. New planets may be discovered, possibly including planets which support life. They will be looking as far as possible into deep space and looking back in time. Light from the most distant objects have been travelling for billions of years, they may even be able to catch sight of the end of the universe. The Subaru will be beneficial to the science of astronomy as all data will be shared with astronomers worldwide. The economic spinoffs and technology have greatly enhanced the Island of Hawaii.

The History and Achievements of the Hubble Telescope
Author: Jeremy Hier

The Hubble Telescope is famous worldwide for its amazing images of the universe. Congress in 1977 voted to fund a project to construct the Hubble. Completion of the telescope was in 1985. The Hubble was supposed to be launched a year later but was delayed because of the 1986 Space Shuttle Challenger disaster.

The Hubble Space Telescope was launched on April 25th, 1990 on the space shuttle. The giant telescope Hubble sent back pictures from space that were out of focus. The giant mirror had a major flaw. It was too flat on one edge 1/50th of the width of a single human hair.

The Space Shuttle Endeavor in December 1993 captured and corrected the Hubble by adding to the telescope a camera to correct problems with the Hubbles mirror. In February 1997 astronauts exchanged some of its instruments and added new blankets to keep Hubble warm. NASA decided on Oct. 1997 to extend its operations from 2005 to 2010.

Hubble's mission in space is to explore the solar system, and measure the age and size of the universe. Hubble's giant telescope searches for our cosmic roots, and charts the evolution of the universe. It also trys to unlock the mysteries of stars, planets, galaxies, and life itself.

Achievements of the Hubble

NASA releases Orion Nebula images from the Hubble in June 1994 that confirms the births of planets around newborn stars in space.

In Nov. 1995 telescope images released by NASA of the "Eagle Nebula" showing where stars are born.

NASA releases the "Deep Field" images in Jan. 1996 in which Hubble looks back in time more than 10 billion years. Revealing at least 1,500 galaxies at various stages of development.

New images of "Ant Nebula" in Feb. 2001.

Hubble Telescope
Author: George Royal -
One of the most important telescopes in the history of astronomy, the Hubble telescope has allowed observers to peer farther into space than any previous telescope. By moving outside and above the atmosphere of the earth, the Hubble telescope has been able to observe visual data much more clearly than a terrestrial telescope, and it has been able to see much farther into the ultraviolet and infrared spectrums as well, since these spectra are largely absorbed by the earth's atmosphere. Thus, by moving the observing platform into open space, the Hubble telescope has given a much clearer view of the universe, allowing scientists to peer even deeper into space.

The Hubble telescope is named for Edwin Hubble, the astronomer who originally determined that the universe is expanding. This discovery, one of the foundations of modern astronomy and cosmology, made Hubble an excellent choice for the honor of having this telescope named for him.

The concept for the Hubble telescope was originally the idea of Lyman Spitzer back in 1946. He clearly saw that earth-based telescopes were inherently limited in their ability to see into the heavens, since dust, clouds, and even turbulence in the atmosphere interfered with telescopes' clarity. Which meant that the best way to get a clear image from a telescope was with a telescope that was in orbit around the earth.

After some success with the smaller Orbiting Astronomical Observatory, the plan for a large scale telescope was born. There were some fits and starts however, mostly due to budget constraints, and the project did not really take off until the 1970's and funding was not approved until 1978. Then, with funding in place, plans were made to launch the Hubble telescope in 1983. However, due to various delays, it was not actually launched until 1990.

After a few early problems, the Hubble telescope finally started sending back clear images. And those images were well worth the effort. The Hubble telescope was able to achieve a sharpness and resolution that was unimaginable with a standard, earth-bound telescope; crisp images that not only showed new detail in known areas of space, but also peered deeper into space than ever before. And with these new images, astronomers have been able to discover new and exciting information about our universe.

However, it is not only astronomers who have been amazed at the images that the Hubble telescope has produced. In fact, the images from Hubble are delights to view all on their own. From the clearly defined galaxies, to pictures of nebulae, to the Apollo 15 landing site, Hubble has been as exciting for the public as it has been for scientists.

As the Hubble telescope ages, its future is uncertain. Corrective software has allowed earth-based telescopes to pick up much of the information previously possible only with a space-based telescope. And as NASA retools itself to follow its mandate to take a man to Mars, money that would be spent on maintenance of the Hubble is being spent elsewhere. However, before the Hubble telescope enters the atmosphere sometime in 2010, it will provide a remarkable window into the universe and all that is in it.
