NASA announced Thursday that members of the general public from around the world will have a chance to suggest a new name for the cutting edge Gamma-ray Large Area Space Telescope, otherwise known as GLAST, observatory before it launches in mid-2008. The satellite will observe some of the most powerful forces known in the universe.

"The idea is to give people a chance to come up with a name that will fully engage the public in the GLAST mission," said Steve Ritz, the mission's project scientist at NASA's Goddard Space Flight Center, Greenbelt, Md.

The mission's scientific objectives are to:

• Explore the most extreme environments in the universe, where nature harnesses energies far beyond anything possible on Earth
  
• Search for signs of new laws of physics and what composes the mysterious dark matter
  
• Explain how black holes accelerate immense jets of material to nearly light speed
  
• Help crack the mysteries of the stupendously powerful explosions known as gamma-ray bursts
  
• Answer long-standing questions about a broad range of phenomena, including solar flares, pulsars and the origin of cosmic rays

"We're looking for name suggestions that will capture the excitement of GLAST’s mission and call attention to gamma-ray and high-energy astronomy. We are looking for something memorable to commemorate this spectacular new astronomy mission," said Alan Stern, associate administrator for Science at NASA Headquarters in Washington. "We hope someone will come up with a name that is catchy, easy to say and will help make the satellite and its mission a topic of dinner table and classroom discussion."

Suggestions for the mission's new name can be an acronym, but it is not a requirement. Any suggestions for naming the telescope after a scientist may only include names of deceased scientists whose names are not already used for other NASA missions. All suggestions will be considered. The period for accepting names closes on March 31, 2008. Participants must include a statement of 25 words or less about why their suggestion would be a strong name for the mission. Multiple suggestions are encouraged.

Anyone who drops a name into the "Name That Satellite!" suggestion box on the Web page can choose to receive a "Certificate of Participation" via return e-mail. Participants also may choose to receive the NASA press release announcing the new mission name. The announcement is expected approximately 60 days after launch of the telescope.

NASA's GLAST mission is an astrophysics and particle physics partnership, developed in collaboration with the U.S. Department of Energy, along with important contributions from academic institutions and partners in France, Germany, Italy, Japan, Sweden, and the U.S.

GLAST arrives in Florida to prepare for launch

NASA's Gamma-ray Large Area Space Telescope, or GLAST, arrived Tuesday at the Astrotech payload processing facility near the Kennedy Space Center to begin final preparations for launch. Liftoff of GLAST aboard a Delta II rocket is currently targeted for 11:45 a.m. EDT on May 16.

GLAST is a collaborative mission with the U.S. Department of Energy, international partners from France, Germany, Italy, Japan and Sweden, and numerous academic institutions from the U.S. and abroad. The spacecraft will explore the most extreme environments in the universe, and answer questions about supermassive black hole systems, pulsars and the origin of cosmic rays. It also will study the mystery of powerful explosions known as gamma-ray bursts.

The milestones to be accomplished over the next two months include attaching the Ku-band communications antenna and the two sets of solar arrays, a complete checkout of GLAST's scientific instruments, installing the spacecraft's battery, and loading aboard the observatory's propellant. These activities will be performed by General Dynamics, builder of the spacecraft for NASA. GLAST currently is scheduled to be transported to Pad 17-B at Cape Canaveral Air Force Station on May 1.

The rocket that will launch GLAST is a Delta II 7920-H, manufactured and prepared for launch by United Launch Alliance. It is a heavier-lift model of the standard Delta II that uses larger solid rocket boosters. The first stage is scheduled to be erected on Pad 17-B the week of March 17.

The following week, the nine strap-on solid rocket boosters will be raised and attached. The second stage, which burns hypergolic propellants, will be hoisted atop the first stage in late March. Next, the fairing that will surround the spacecraft will be hoisted into the clean room of the mobile service tower.

Engineers will perform several tests of the Delta II. In late April, the first stage will be loaded with liquid oxygen and checked for leaks. The following day, a simulated flight test will be performed, testing the vehicle's post-liftoff flight events without fuel aboard. The electrical and mechanical systems of the entire Delta II will be exercised during this test.

Once the GLAST payload is atop the launch vehicle, a final major test will be performed. The combined minus count and plus count test simulates all events as they will occur on launch day, but without propellants aboard the vehicle.

The NASA Launch Services Program at Kennedy Space Center is responsible for the countdown and launch management of the Delta II GLAST mission.
