STS-122 astronauts get ready for Earth

Houston -- The U.S. space agency was preparing for a Wednesday return to Earth and the end of STS-122's 13-day, 5.3 million-mile space mission.

The crew of space shuttle Atlantis was scheduled Tuesday to, among other things, test the spacecraft's thrusters and control surfaces for its flight
through the atmosphere.

The STS-122 astronauts also were to set up a recumbent landing seat for astronaut Daniel Tani, who boarded the Atlantis at the International Space Station. Tani, who worked on the space station for nearly four months, was replaced by European Space Agency astronaut Leopold Eyharts. The seat is designed to help Tani adjust to Earth's gravity after spending so much time in weightlessness.

NASA controllers in Houston said Wednesday's landing opportunities at the Kennedy Space Center were 9:07 a.m. and 10:42 a.m. EST. There were additional opportunities at 12:12 p.m. and 1:47 p.m. EST at Edwards Air Force Base, Calif., which is a backup landing site.

NASA Awards Reusable Solid Rocket Contract

Washington -- The U.S. space agency has awarded a contract to ATK Launch Systems Inc. of Brigham City, Utah, for delivery of space shuttle reusable solid rocket motors.

The National Aeronautics and Space Administration said the modification contract, valued at $812.5 million, changes the current contract to align production to launch schedule requirements through Sept. 30, 2010. The modification reflects adjustments made in the shuttle manifest and makes deliveries consistent with the planned retirement of the space shuttle in September 2010.

ATK will produce and refurbish flight and ground-test reusable solid rocket motors for the space shuttle program under the cost-plus-award fee contract, which was initially awarded in October 1998.

Work will be performed at the contractor's plants in Brigham City and Clearfield, Utah, along with facilities at NASA's Marshall Space Flight Center in Huntsville, Ala., and NASA's Kennedy Space Center in Florida.

NASA looks at future astronomy missions

Washington -- The U.S. space agency has selected 19 science teams to conduct year-long studies of new concepts for its next generation of major space observatories.

The National Aeronautics and Space Administration said every 10 years U.S. astronomers and physicists take part in the Astronomy and Astrophysics Decadal Survey in cooperation with the National Academy of Sciences. They produce directions that guide federal agencies such as NASA and the National Science Foundation in planning astronomy and astrophysics programs for the coming decade. "The exciting new astrophysics mission concept studies we are funding will seed preparations for astronomical space missions and paradigm-shifting discoveries across the early 21st century," said Alan Stern, associate administrator for NASA's Science Mission Directorate.

NASA revises shuttle launch dates

Cape Canaveral, Fla -- The U.S. space agency has revised the launch dates for space shuttle flights during the second half of 2008, necessitated by the delayed STS-122 launch.

The National Aeronautics and Space Administration said the next two shuttle flights -- STS-123 on shuttle Endeavour targeted for March 11 and STS-124 on Discovery targeted for April 24 -- haven't been changed. Any decision regarding those launch dates will take place after the current STS-122 mission, aboard the space shuttle Atlantis, lands Wednesday.

Late 2008 shuttle mission revised target launch dates are:

Aug. 28 -- Atlantis (STS-125) to service the Hubble Space Telescope.

Oct. 16 -- Endeavour (STS-126) to deliver equipment to the International Space Station.

Dec. 4 -- Discovery (STS-119) to deliver the final set of solar arrays to the space station.

NASA offers university scholarships

Washington -- The National Aeronautics and Space Administration is accepting applications for its fall 2008 scholarship program in aeronautics and related fields.

NASA's Aeronautics Research Mission Directorate said it will accept applications from undergraduate and graduate students between Feb. 22 and Mar. 17 for the program, which is designed to attract highly-motivated students for space-related studies.

Undergraduates in their second year of study can earn up to $15,000 per year for two years, and graduate students can earn up to $35,000 per year for three years. The money can be used for tuition, room and board, and other school-related expenses.

Students also can apply for optional summer internships at NASA research centers to earn an additional $10,000 in stipends.

Endeavour moves to launchpad

Cape Canaveral, Fla. -- Space shuttle Endeavour arrived at its launchpad Monday at the Kennedy Space Center in Florida, in advance of its scheduled March 11 launch.

The rollout of the shuttle began at 11:24 p.m. Sunday, approximately seven hours earlier than scheduled. The shuttle and its STS-123 crew will conduct a 16-day mission to the International Space Station.

The fully assembled space shuttle, consisting of the orbiter, external fuel tank and twin solid rocket boosters were mounted on a mobile launcher platform and delivered to the pad on top of a crawler transporter. It was secured at 6:22 a.m. Monday.

In addition, as part of the National Aeronautics and Space Administration's 50th anniversary, the U.S. Air Force Thunderbirds were to fly over Endeavour at the launch pad during a midmorning ceremony.

Atlantis Begins Its Journey Back to Earth

Houston -- Space shuttle Atlantis ended its nearly nine-day mission to the International Space Station by undocking at 4:24 a.m. Monday.

The National Aeronautics and Space Administration said shortly after separation, the shuttle flew around the space station to allow a close inspection of its heat shield prior to setting course for Earth.

The shuttle arrived at the station Feb. 9, delivering the European Space Agency's Columbus laboratory. The crews installed Columbus Feb. 11 and conducted three spacewalks to prepare Columbus for its scientific work. They also replaced an expended nitrogen tank on the station's P1 truss.

In addition, Atlantis delivered a new station crew member, flight engineer Leopold Eyharts, an ESA astronaut. He replaced astronaut Daniel Tani, who is returning to Earth aboard Atlantis.

Astronauts complete spacewalk duties

Houston-- NASA says two astronauts upgraded science facilities for studying the sun during a seven-hour spacewalk Friday outside the shuttle Atlantis.

Rex Walheim and Stan Love bolted two packages for solar experiments onto the outside of the International Space Station and examined a dent in the station's skin, USA Today reported Saturday.

NASA is trying to determine whether the dent, located on a handrail near the door, is responsible for a puzzling series of snags in astronauts' spacesuits during the last 18 months. None of the astronauts were injured, but NASA officials feared a deep cut could allow air to leak from their suits, USA Today said.

"It is a little bit rough. I can feel it snagging," Walheim said in describing the dent to Mission Control. Walheim and Love are scheduled to return to Earth aboard Atlantis Wednesday.

Endeavour to be moved to launch pad

Cape Canaveral, Fla. -- The U.S. space agency announced plans Tuesday to move space shuttle Endeavour to its launch pad in advance of its March 11 launch.

The National Aeronautics and Space Administration said Endeavour's move to Launch Pad 39A at the Kennedy Space Center next Monday is in preparation for the STS-123's 16-day mission to the International Space Station. That mission will include delivery of the first section of the Japan space agency's Kibo laboratory and the Canadian Space Agency's two-armed robotic system, Dextre. Five spacewalks are scheduled for the flight.

The first motion of the shuttle from Kennedy's Vehicle Assembly Building is scheduled for 7 a.m. EST Monday. The fully assembled space shuttle -- the orbiter, external tank and twin solid rocket boosters -- will be mounted on a mobile launcher platform and delivered to the pad on top of a crawler transporter.

NASA assigns STS-127, Expedition 19 crews

Washington -- The U.S. space agency has assigned the crews for the STS-127 space shuttle mission and the Expedition 19 International Space Station mission.

The Endeavour space shuttle's STS-127 mission is to deliver the final components of the Japanese space agency's Kibo laboratory to the space station. Expedition 19 will double the size of the station's resident crew to six people.

Mark Polansky will command Endeavour for STS-127, targeted to launch in 2009. Marine Lt. Col. Douglas Hurley will serve as pilot, with astronauts Christopher Cassidy, Thomas Marshburn, David Wolf and Julie Payette, a Canadian Space Agency astronaut, onboard.

The mission will deliver U.S. Army Col. Timothy Kopra to the station to join Expedition 18 as a flight engineer and science officer and return Japanese astronaut Koichi Wakata to Earth. Hurley, Cassidy, Marshburn and Kopra will be making their first trips into space.

Deep Impact searches for exosolar planets

Greenbelt, Md. -- The U.S. space agency's Deep Impact spacecraft is aiming its largest telescope at five stars in a search for extrasolar planets.

Deep Impact made history July 4, 2005, when National Aeronautics and Space Administration scientists directed an probe into comet Tempel 1. The spacecraft has been redirected for a flyby of comet Hartley 2 on Oct. 11, 2010.

As it cruises toward the comet, Deep Impact is observing five nearby stars with planets passing between its star and Deep Impact. Those observations began Jan. 22, NASA said.

However, if there are also other worlds around those stars, they might also pass by the star and be discovered by the spacecraft.

"We're on the hunt for planets down to the size of Earth, orbiting some of our closest neighboring stars," said Deputy Principal Investigator Drake Deming of NASA's Goddard Space Flight Center in Greenbelt, Md.

NASA wants help in re-naming telescope

Washington -- The U.S. space agency is asking the public for help in re-naming the cutting edge Gamma-ray Large Area Space Telescope, otherwise known as GLAST.

The space observatory, targeted for launch later this year, is designed to observe some of the universe's most powerful forces in a search for signs of new laws of physics and what composes the mysterious dark matter.

"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," said Alan Stern NASA's associate administrator for science. "We are looking for something memorable to commemorate this spectacular new astronomy mission. 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."
