It will be Earth vs. space in a unique chess match, and you can help Earth win. NASA and the U.S. Chess Federation (USCF) are teaming up to host the first public chess match between International Space Station astronaut Greg Chamitoff and the inhabitants of the Earth, beginning Monday, Sept. 29.

Key players in the game will be the kindergarten through third grade U.S. Chess Championship Team and its chess club teammates from Stevenson Elementary School in Bellevue, Wash. The K-3 champions will select up to four possible moves on Earth's turn. The public then will vote on the move transmitted to orbit. The USCF will facilitate the match on its Web site at:

"For the past 10 years, the International Space Station has been an important platform to learn about living in space. We're excited to have the opportunity to engage not only young students, but the public at large in this unique chess match," said Heather Rarick, lead flight director for the current space station mission at NASA's Johnson Space Center in Houston.

"We hope the excitement and interest this game generates will inspire students to become interested in chess," said USCF Executive Director Bill Hall. "Chess is a valuable tool to lead students to become interested in math and to develop critical thinking skills, objectives we focus on in our work with schools nationwide."

Chamitoff, a space station flight engineer speeding about 210 miles above the Earth at five miles a second, is a chess aficionado. He brought a chess set with him when he arrived at the complex on the STS-124 space shuttle mission in June. Chamitoff has added Velcro to the chess pieces to keep them from floating away in weightlessness. He has been playing long-distance chess during his mission in his off time with station control centers around the world. So far, he is undefeated.

The game against the public will move at a pace of one move per day on weekdays only. Play may be slower, however, because Chamitoff only makes moves when his workload permits.

NASA's Mars Reconnaissance Orbiter has revealed hundreds of small fractures exposed on the Martian surface that billions of years ago directed flows of water through underground Martian sandstone.

Researchers used images from the spacecraft's High Resolution Imaging Science Experiment, or HiRISE, camera. Images of layered rock deposits at equatorial Martian sites show the clusters of fractures to be a type called deformation bands, caused by stresses below the surface in granular or porous bedrock.

"Groundwater often flows along fractures such as these, and knowing that these are deformation bands helps us understand how the underground plumbing may have worked within these layered deposits," said Chris Okubo of the U.S. Geological Survey in Flagstaff, Ariz.

Visible effects of water on the color and texture of rock along the fractures provide evidence that groundwater flowed extensively along the fractures.

"These structures are important sites for future exploration and investigations into the geological history of water and water-related processes on Mars," Okubo and co-authors state in a report published online this month in the Geological Society of America Bulletin.

Deformation band clusters in Utah sandstones, as on Mars, are a few yards wide and up to a few miles long. They form from either compression or stretching of underground layers, and can be
precursors to faults. The ones visible at the surface have become exposed as overlying layers erode away. Deformation bands and faults can strongly influence the movement of groundwater on Earth and appear to have been similarly important on Mars, according to this study.

"This study provides a picture of not just surface water erosion but true groundwater effects widely distributed over the planet," said Suzanne Smrekar, deputy project scientist for the Mars Reconnaissance Orbiter at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "Ground water movement has important implications for how the temperature and chemistry of the crust have changed over time, which in turn affects the potential for habitats for past life."

The recent study focuses on layered deposits in Mars' Capen crater, approximately 43 miles in diameter and 7 degrees north of the equator. This formerly unnamed crater became notable due to this discovery of deformation bands within it and was recently assigned a formal name. The crater was named for the late Charles Capen, who studied Mars and other objects as an astronomer at JPL's Table Mountain Observatory in southern California and at Lowell
Observatory, Flagstaff, Ariz.

The HiRISE camera is one of six science instruments on the orbiter. It can reveal smaller details on the surface than any previous camera to orbit Mars. The orbiter reached Mars in March 2006 and has returned more data than all other current and past missions to Mars combined.

The mission is managed by JPL for NASA's Science Mission Directorate. Lockheed Martin Space Systems of Denver built the spacecraft. The University of Arizona operates the HiRISE camera, built by Ball Aerospace and Technology Corp. of Boulder, Colo.

Images of the deformation band clusters and additional information about the mission are on the Internet at:

Members of the public can send their names around Earth on NASA's Glory satellite, the first mission dedicated to understanding the effects of particles in the atmosphere and the sun's variability on our climate.

The "Send Your Name Around the Earth" Web site enables everyone to take part in the science mission and place their names in orbit for years to come. The Web site, where participants can submit their information, is located at:

Participants will receive a printable certificate from NASA and have their name recorded on a microchip that will become part of the spacecraft. The deadline for submitting names is Nov. 1, 2008.

The Glory satellite will allow scientists to measure airborne particles more accurately from space than ever before. The particles, known as "aerosols," are tiny bits of material found in Earth's atmosphere, like dust and smog.

"Undoubtedly, greenhouse gases cause the biggest climatic effect," said Michael Mishchenko, the Glory project scientist at NASA's Goddard Institute for Space Studies in New York. "But the uncertainty in the aerosol effect is the biggest uncertainty in climate at the present."

Glory will carry two scientific instruments, the Aerosol Polarimetry Sensor, or APS, and the Total Irradiance Monitor, or TIM, and two cameras for cloud identification. The APS instrument will help quantify the role of aerosols as natural and human-produced agents of climate change more accurately than existing measurement tools. The TIM instrument will continue 30 years of measuring total solar irradiance, the amount of energy radiating from the sun to Earth, with improved accuracy and stability. Understanding the sun's energy is an important key to understanding climate change on Earth.

Glory is scheduled for launch in June 2009 from Vandenberg Air Force Base in California. Glory will orbit as part of the Afternoon Constellation, or "A-Train," a series of Earth-observing satellites. The A-Train spacecraft follow each other in close formation, crossing the equator a few minutes apart shortly after 1:30 p.m. local time each day. The A-Train orbits Earth once every 100 minutes.
NASA's Goddard Space Flight Center in Greenbelt, Md., is responsible for Glory project management. Orbital Sciences Corporation in Dulles, Va., is responsible for development, integration and operations of the spacecraft. Raytheon in El Segundo, Calif., is responsible for development of the APS. The Laboratory for Atmospheric and Space Physics in Boulder, Colo., is responsible for the development of the TIM. Glory's cloud cameras were built by Ball Aerospace and Technologies of Boulder.

The target launch date for space shuttle Atlantis' STS-125 mission to service the Hubble Space Telescope has been reset to Oct. 14 at 10:19 p.m. EDT. A news conference is scheduled for Friday, Oct. 3, at NASA's Kennedy Space Center in Florida to announce an official launch date.

With the delay of Atlantis' launch from Oct. 10 to Oct. 14, shuttle Endeavour's STS-126 supply mission to the International Space Station, also will move from Nov. 12 to Nov. 16 at 7:07 p.m. EST. The target launch date adjustments were made Wednesday during the Space Shuttle Program's Flight Readiness Review, which concludes Thursday.

Detailed assessments were presented Wednesday by Mission Operations, Flight Crew Operations, and training divisions affected by the closure of the NASA's Johnson Space Center in Houston, as a result of Hurricane Ike. While vehicle processing at Kennedy continues on schedule, the lost week of training and mission preparation due to the impacts of the storm led to the decision to slip the dates.

The Oct. 3 news conference will follow the Flight Readiness Review, a meeting to assess preparations for the STS-125 mission to Hubble, and will begin no earlier than 4 p.m. EDT.

The briefing participants are:
- Associate Administrator for Space Operations Bill Gerstenmaier
- Deputy Associate Administrator for Programs, Science Mission Directorate Mike Luther
- Space Shuttle Program Manager John Shannon
- STS-125 Launch Director Ed Mango

NASA Television and the agency's Web site will broadcast the briefing live. Media may ask questions from participating NASA locations. Reporters should contact their preferred NASA center to confirm its participation.

Data from the Ulysses spacecraft, a joint NASA-European Space Agency mission, show the sun has reduced its output of solar wind to the lowest levels since accurate readings became available. The sun's current state could reduce the natural shielding that envelops our solar system.

"The sun's million mile-per-hour solar wind inflates a protective bubble, or heliosphere, around the solar system. It influences how things work here on Earth and even out at the boundary of our solar system where it meets the galaxy," said Dave McComas, Ulysses' solar wind instrument principal investigator and senior executive director at the Southwest Research Institute in San Antonio. "Ulysses data indicate the solar wind's global pressure is the lowest we have seen since the beginning of the space age."

The sun's solar wind plasma is a stream of charged particles ejected from the sun's upper atmosphere. The solar wind interacts with every planet in our solar system. It also defines the border between our solar system and interstellar space. This border, called the heliopause, surrounds our solar system where the solar wind's strength is no longer great enough to push back the wind of other stars. The region around the heliopause also acts as a shield for our solar system, warding off a significant portion of the cosmic rays outside the galaxy.

"Galactic cosmic rays carry with them radiation from other parts of our galaxy," said Ed Smith, NASA's Ulysses project scientist at the Jet Propulsion Laboratory in Pasadena, Calif. "With the solar wind at an all-time low, there is an excellent chance the heliosphere will diminish in size and strength. If that occurs, more galactic cosmic rays will make it into the inner part of our solar system."

Galactic cosmic rays are of great interest to NASA. Cosmic rays are linked to engineering decisions for unmanned interplanetary spacecraft and exposure limits for astronauts traveling beyond low-Earth orbit.

In 2007, Ulysses made its third rapid scan of the solar wind and magnetic field from the sun's south to north pole. When the results were compared with observations from the previous solar cycle, the strength of the solar wind pressure and the magnetic field embedded in the solar wind were found to have decreased by 20 percent. The field strength near the spacecraft has decreased by 36 percent. "The sun cycles between periods of great activity and lesser activity," Smith said. "Right now, we are in a period of minimal activity that has stretched on longer than anyone anticipated."

Ulysses was the first mission to survey the space environment over the sun's poles. Data Ulysses has returned have forever changed the way scientists view our star and its effects. The venerable spacecraft has lasted more than 18 years, or almost four times its expected mission lifetime. The Ulysses solar wind findings were published in a recent edition of Geophysical Research Letters.

The Ulysses spacecraft was carried into Earth orbit aboard space shuttle Discovery on Oct. 6, 1990. From Earth orbit it was propelled toward Jupiter, passing the planet on Feb. 8, 1992. Jupiter's immense gravity bent the spacecraft's flight path downward and away from the plane of the planets' orbits. This placed Ulysses into a final orbit around the sun that would take it over its north and south poles.

The Ulysses spacecraft was provided by ESA, having been built by Astrium GmbH (formerly Dornier Systems) of Friedrichshafen, Germany. NASA provided the launch vehicle and the upper stage boosters. The U.S. Department of Energy supplied a radioisotope thermoelectric generator to power the spacecraft. Science instruments were provided by U.S. and European investigators. The spacecraft is operated from JPL by a joint NASA-ESA team.

More information about the Ulysses mission is available on the Web at:

NASA's Phoenix Lander Might Peek Under a Rock

If the robotic arm on NASA's Phoenix Mars Lander can nudge a rock aside today, scientists on the Phoenix team would like to see what's underneath.

Engineers who develop commands for the robotic arm have prepared a plan to try displacing a rock on the north side of the lander. This rock, roughly the size and shape of a VHS videotape, is informally named "Headless."

"We don't know whether we can do this until we try," said Ashitey Trebi Ollennu, a robotics engineer at NASA's Jet Propulsion Laboratory, Pasadena, Calif. "The idea is to move the rock with minimum disturbance to the surface beneath it. You have to get under it enough to lift it as you push it and it doesn't just slip off the scoop."

The lander receives commands for the whole day in the morning, so there's no way to adjust in mid-move if the rock starts slipping. Phoenix took stereo-pair images of Headless to provide a detailed three-dimensional map of it for planning the arm's motions. On Saturday, Sept. 20, the arm enlarged a trench close to Headless. Commands sent to Phoenix Sunday evening, Sept. 21, included a sequence of arm motions for today, intended to slide the rock into the trench.

Moving rocks is not among the many tasks Phoenix's robotic arm was designed to do. If the technique works, the move would expose enough area for digging into the soil that had been beneath Headless.

"The appeal of studying what's underneath is so strong we have to give this a try," said Michael Mellon, a Phoenix science team member at the University of Colorado, Boulder.

The scientific motive is related to a hard, icy layer found beneath the surface in trenches that the robotic arm has dug near the lander. Excavating down to that hard layer underneath a rock might provide clues about processes affecting the ice.

"The rocks are darker than the material around them, and they hold heat," Mellon said. "In theory, the ice table should deflect downward under each rock. If we checked and saw this deflection, that would be evidence the ice is probably in equilibrium with the water vapor in the atmosphere."

An alternative possibility, if the icy layer were found closer to the surface under a rock, could be the rock collecting moisture from the atmosphere, with the moisture becoming part of the icy layer.

The Phoenix mission is led by Smith at the University of Arizona with project management at NASA's Jet Propulsion Laboratory in Pasadena, Calif., and development partnership at Lockheed Martin in Denver. International contributions come from the Canadian Space Agency; the University of Neuchatel, Switzerland; the universities of Copenhagen and Aarhus in Denmark; the Max Planck Institute in Germany; and the Finnish Meteorological Institute.

NASA and the United States Air Force are looking for university and industry partners as they work to advance hypersonic research.

NASA's Aeronautics Research Mission Directorate in Washington and the Air Force Research Laboratory's Office of Science Research at Wright-Patterson Air Force Base in Dayton, Ohio, have released a broad agency announcement describing their intent to establish three national hypersonic science centers. Hypersonic speed is defined as Mach 5, or five times the speed of sound, and faster.

NASA's Fundamental Aeronautics Program and the Air Force Office of Science Research plan to set aside as much as $30 million to fund the centers over five years. The maximum grant will be approximately $2 million a year. The jointly funded program will support university-level basic science or engineering research that provides improved understanding of hypersonic flight.

"We have identified three critical research areas: air-breathing propulsion, materials and structures, and boundary layer control," said James Pittman, principal investigator for NASA's Fundamental Aeronautics Program's Hypersonics Project at NASA's Langley Research Center in Hampton, Va. "These three areas are the biggest hurdles to successful hypersonic flight and low-cost space access using an air-breathing engine."

Details about the announcement and the process for submitting proposals are available at:

NASA's Mars Rover to Head Toward Bigger Crater

NASA's Mars Rover Opportunity is setting its sights on a crater more than 20 times larger than its home for the past two years.

To reach the crater the rover team calls Endeavour, Opportunity would need to drive approximately 12 kilometers (7 miles) to the southeast, matching the total distance it has traveled since landing on Mars in early 2004. The rover climbed out of Victoria Crater earlier this month.

"We may not get there, but it is scientifically the right direction to go anyway," said Steve Squyres of Cornell University, principal investigator for the science instruments on Opportunity and its twin rover, Spirit. "This crater is staggeringly large compared to anything we've seen before."

Getting there would yield a look inside a bowl 22 kilometers (13.7 miles) across. Scientists expect to see a much deeper stack of rock layers than those examined by Opportunity in Victoria Crater.

"I would love to see that view from the rim," Squyres said. "But even if we never get there, as we move southward we expect to be getting to younger and younger layers of rock on the surface. Also, there are large craters to the south that we think are sources of cobbles that we want to examine out on the plain. Some of the cobbles are samples of layers deeper than Opportunity will ever see, and we expect to find more cobbles as we head toward the south."

Opportunity will have to pick up the pace to get there. The rover team estimates Opportunity may be able to travel about 110 yards each day it is driven toward the Endeavour crater. Even at that pace, the journey could take two years.

"This is a bolder, more aggressive objective than we have had before," said John Callas, the project manager for both Mars rovers at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "It's tremendously exciting. It's new science. It's the next great challenge for these robotic explorers."

Opportunity, like Spirit, is well past its expected lifetime on Mars, and might not keep working long enough to reach the crater. However, two new resources not available during the 4-mile drive toward Victoria Crater in 2005 and 2006 are expected to aid in this new trek.

One is imaging from orbit of details smaller than the rover itself, using the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter, which arrived at the Red Planet in 2006.

"HiRISE allows us to identify drive paths and potential hazards on the scale of the rover along the route," Callas said. "This is a great example of how different parts of NASA's Mars Exploration Program reinforce each other."

Other advantages come from a new version of flight software uplinked to Opportunity and Spirit in 2006, boosting their ability to autonomously choose routes and avoid hazards such as sand dunes.

During its first year on Mars, Opportunity found geological evidence that the area where it landed had surface and underground water in the distant past. The rover's explorations since have added information about how that environment changed over time. Finding rock layers above or below the layers already examined adds windows into later or earlier periods of time.

NASA's JPL built and manage the rovers and the Mars Reconnaissance Orbiter for NASA's Science Mission Directorate, Washington.

Taback: Godfather to Viking and a Fair Number of Engineers

Project scientist Gerry Soffen called Israel Taback the "father of the Mars Viking Lander," parentage that Taback rejected with his usual wry wit.

"He thought I was because I was responsible for most of the atmosphere surrounding the lander," Taback said. "Remember, there were over 150 Martin (Marietta) people and over 150 Langley people involved -- all talented, outstanding people. It didn't need a father.

"More of a godfather."

That was a role Taback – who passed away on August 30 -- could play naturally and did, from days when Langley was the National Advisory Committee for Aeronautics laboratory and he helped shepherd the X-15's instrumentation through its supersonic flights.

He carried the role through the transition into NASA, when he was chief engineer of one of the first of the new agency's projects, the Lunar Orbiter, which still ranks among NASA's most successful missions. Five Lunar Orbiters circled the moon, three taking pictures of places where Apollo could land, two mapping 99 percent of the lunar surface.

Then Taback went on to become deputy project manager for Mars Viking, in charge of building the lander that provided information that has been used for more than 30 years and will be used when NASA sends astronauts there, scheduled 22 years hence.

"I had the extraordinary opportunity to work under Iz's leadership for more than a decade," said Tom Young, who eventually became director at Goddard Space Flight Center before becoming an aerospace industry executive. "It's hard to imagine what a special thing it is for a young engineer to have that opportunity. Iz is clearly the best systems engineer I've ever known."

Said Fil Cuddihy, who assisted Taback on the technical side of Mars Viking: "I think Iz was just a wise mentor to everybody who had the privilege of working with him. He taught us all."

Small and slight of stature, Taback could teach so well because he had a natural curiosity and the kind of amazing intellect that made him challenge himself by doing things like working out the value of "pi" to 19 decimal places – in his head. For the curious, it's 3.1415926535897932385.

"I never spent a day in eight years without learning something after talking to Iz," said Gus Guastaferro, who worked on the business side of Mars Viking before leaving Langley for private business. "It was like going to school.

"He would ask the question I wouldn't ask. He would say, 'Fundamentally, that doesn't make sense to me. Explain it to me again,' and I would say, 'I'm glad he asked that because I didn't have the courage to ask it.' I wouldn't want my group to think I didn't know."

As much as anything, it was Taback issuing a Socratic challenge.

"He knew the answer," Guastaferro said. "He wanted to see what you were made of. He was testing you, not in a cruel sense and not in an aggressive sense, but in a way of letting you pass muster so he could gain confidence in what you were trying to sell him."

If it was "no sale," well, Taback had ways of dealing with that, too.

"I hadn't been working with NASA long and we had an outside contractor come in and make a presentation to Iz," Cuddihy said. "Iz gently poked and probed, and the guy didn't pay any attention. He had an agenda that he was going to sell.

"Finally, Iz said, 'well, you may be right,' and the guy went on with his presentation. What he didn't know was 'well, you may be right' was Iz saying, 'I'm done with you.' "

No sale.

Norm Crabill, who worked with Taback on Lunar Orbiter and Mars Viking, talked of a Taback technique that disarmed some.

"When you had a product and you gave it to an engineer and they went off and did all of these big computer programs, Iz would say, 'let's see if this is right,' " Crabill remembered. "He would go to a blackboard, even without a slide rule, and he would get an approximate answer. 'Yeah, that's right,' he would say, because the engineer's answer agrees with his approximate answer."

Young remembers sessions with Taback and a blackboard.

"Iz taught us that when you have a difficult technical problem, you don't solve it with meetings," Young said. "You don't solve it with consultants. You solve it by going back to basic principles. When Iz Taback would pick up a piece of chalk and go to a blackboard and say, 'let's go back to basic principles,' it was like watching a great master at work."

What the engineers came to realize was that Taback could do some of the quick calculations because he had already queried them about their methods. It was part of his management style.

"It was 'management by walking around,' " Guastaferro said. "He would walk around the Viking office and say, 'what are you doing?' He'd look at your in-basket and see it piling up because that was the days before e-mail. He would grab it and throw it in the garbage. He would say, 'you don't need that. Get around and talk to the people.' "

The young engineers would, of course, retrieve the contents of their in-basket, but then they would walk over to somebody else, to talk through problems.

There was some question as to whether Taback ever became comfortable with a computer. A chalkboard or a pencil and paper was more to his liking.

When Taback passed away, he was working on a car rack for his new adult tricycle. Two pages of penciled notes, sketches and engineering formulas were worked out, an 88-year-old man seeming to punctuate a 66-year career of engineering with one more design.


For the first time since July 2001, two shuttles are on the launch pads at the same time at NASA's Kennedy Space Center. Space shuttle Endeavour completed a 4.2-mile journey to
Launch Pad 39B on Friday, Sept. 19, at 6:59 a.m. EDT.

Endeavour left Kennedy's Vehicle Assembly Building at 11:15 p.m. Thursday, traveling at less than 1 mph atop a massive crawler-transporter.

Endeavour will stand by at pad B in the unlikely event that a rescue mission is necessary during space shuttle Atlantis' upcoming mission to repair NASA's Hubble Space Telescope, targeted to launch Oct. 10. After Endeavour is cleared from its duty as a rescue spacecraft, it will be moved to Launch Pad 39A for the STS-126 mission to the International Space Station. That flight is targeted for launch Nov. 12.

NASA's Swift satellite has found the most distant gamma-ray burst ever detected. The blast, designated GRB 080913, arose from an exploding star 12.8 billion light-years away.

"This is the most amazing burst Swift has seen," said the mission's lead scientist Neil Gehrels at NASA's Goddard Space Flight Center in Greenbelt, Md. "It's coming to us from near the edge of the visible universe."

Because light moves at finite speed, looking farther into the universe means looking back in time. GRB 080913's "lookback time" reveals that the burst occurred less than 825 million years after the universe began.

The star that caused this "shot seen across the cosmos" died when the universe was less than one-seventh its present age. "This burst accompanies the death of a star from one of the universe's early generations," says Patricia Schady of the Mullard Space Science Laboratory at University College London, who is organizing Swift observations of the event.

Gamma rays from the far-off explosion triggered Swift's Burst Alert Telescope at 1:47 a.m. EDT on Sept. 13. The spacecraft established the event's location in the constellation Eridanus and quickly turned to examine the spot. Less than two minutes after the alert, Swift's X-Ray Telescope began observing the position. There, it found a fading, previously unknown X-ray source.

Astronomers on the ground followed up as well. Using a 2.2-meter telescope at the European Southern Observatory in La Silla, Chile, a group led by Jochen Greiner at the Max Planck Institute for Extraterrestrial Physics in Garching, Germany, captured the bursts fading afterglow.

The telescope's software listens for alerts from Swift and automatically slewed to the burst position. Then, the team's Gamma-Ray Burst Optical/Near-Infrared Detector, or GROND,
simultaneously captured the waning light in seven wavelengths. "Our first exposure began just one minute after the X-Ray Telescope started observing," Greiner says.

In certain colors, the brightness of a distant object shows a characteristic drop caused by intervening gas clouds. The farther away the object is, the longer the wavelength where this fade-out begins. GROND exploits this effect and gives astronomers a quick estimate of an explosion's shift toward the less energetic red end of the electromagnetic spectrum, or "redshift," which suggests its record-setting distance.

An hour and a half later, as part of Greiner's research, the Very Large Telescope at Paranal, Chile, targeted the afterglow. Analysis of the spectrum with Johan Fynbo of the University of Copenhagen established the blasts redshift at 6.7 -- among the most distant objects known.

Gamma-ray bursts are the universe's most luminous explosions. Most occur when massive stars run out of nuclear fuel. As their cores collapse into a black hole or neutron star, gas jets -- driven by processes not fully understood -- punch through the star and blast into space. There, they strike gas previously shed by the star and heat it, which generates bright afterglows.

The previous record holder was a burst with a redshift of 6.29, which placed it 70 million light-years closer than GRB 080913.

Swift, launched in November 2004, has had a banner year. In March, the satellite detected the brightest gamma-ray burst, which was visible to the human eye despite occurring billions of light-years away. And in January, the spacecraft's instruments caught the first X-rays from a new supernova days before optical astronomers saw the exploding star.

Swift is managed by Goddard. It was built and is being operated in collaboration with Penn State University, University Park, Pa., the Los Alamos National Laboratory in New Mexico, and General Dynamics of Gilbert, Ariz., in the U.S. International collaborators include the University of Leicester and Mullard Space Sciences Laboratory in the United Kingdom, Brera Observatory and the Italian Space Agency in Italy, and additional partners in Germany and Japan.

NASA's Johnson Space Center in Houston is scheduled to reopen Monday, Sept. 22, ending its closure related to Hurricane Ike. Johnson shut down Sept. 11 as Ike approached the Texas coast.

International Space Station flight control is scheduled to resume from Mission Control in Houston during the morning of Friday, Sept. 19. Station flight control was transferred to a backup facility near Austin, Texas, and later, to another facility at the Marshall Space Flight Center in Huntsville, Ala.

The Mission Control Center and other key Johnson facilities are largely unscathed, partly because of extensive preparations and the work of a hurricane rideout team of more than 60 people. However, some center buildings suffered roof, window and facade damage. Several light poles were downed, as were a number of trees. The damage assessment and cleanup continues.

Johnson employees should check the center's Employee Information Line for status updates at 281-483-3351, and are encouraged to contact their supervisors if they have not already done so. NASA has a public Web site to distribute important information for NASA employees and
contractors impacted by Hurricane Ike at:

NASA Selects 'MAVEN' Mission to Study Mars Atmosphere

NASA has selected a Mars robotic mission that will provide information about the Red Planet's atmosphere, climate history and potential habitability in greater detail than ever before.

Called the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft, the $485 million mission is scheduled for launch in late 2013. The selection was evaluated to have the best science value and lowest implementation risk from 20 mission investigation proposals submitted in response to a NASA Announcement of Opportunity in August 2006.

"This mission will provide the first direct measurements ever taken to address key scientific questions about Mars' evolution," said Doug McCuistion, director of the Mars Exploration Program at NASA Headquarters in Washington.

Mars once had a denser atmosphere that supported the presence of liquid water on the surface. As part of a dramatic climate change, most of the Martian atmosphere was lost. MAVEN will make definitive scientific measurements of present-day atmospheric loss that will offer clues about the planet's history.

"The loss of Mars' atmosphere has been an ongoing mystery," McCuistion said. "MAVEN will help us solve it."

The principal investigator for the mission is Bruce Jakosky of the Laboratory for Atmospheric and Space Physics at the University of Colorado at Boulder. The university will receive $6 million to fund mission planning and technology development during the next year. NASA's Goddard Space Flight Center in Greenbelt, Md., will manage the project. Lockheed Martin of Littleton, Colo., will build the spacecraft based on designs from NASA's Mars Reconnaissance Orbiter and 2001 Mars Odyssey missions. The team will begin mission design and implementation in the fall of 2009.

Launched in August 2005, the Mars Reconnaissance Orbiter is a multipurpose spacecraft that carries the most powerful telescopic camera ever flown to another planet. The camera can show Martian landscape features as small as a kitchen table from low orbital altitudes. The mission is examining potential landing sites for future surface missions and providing a communications relay for other Mars spacecraft.

The 2001 Mars Odyssey, launched in April of that year, is determining the composition of the Red Planet's surface by searching for water and shallow buried ice. The spacecraft also is studying the planet's radiation environment.

After arriving at Mars in the fall of 2014, MAVEN will use its propulsion system to enter an elliptical orbit ranging 90 to 3,870 miles above the planet. The spacecraft's eight science instruments will take measurements during a full Earth year, which is roughly equivalent to half of a Martian year. MAVEN also will dip to an altitude 80 miles above the planet to sample Mars' entire upper atmosphere. During and after its primary science mission, the spacecraft may be used to provide communications relay support for robotic missions on the Martian surface.

"MAVEN will obtain critical measurements that the National Academy of Science listed as being of high priority in their 2003 decadal survey on planetary exploration," said Michael Meyer, the Mars chief scientist at NASA Headquarters. "This field of study also was highlighted in the 2005 NASA Roadmap for New Science of the Sun-Earth System Connection."

The Mars Scout Program is designed to send a series of small, low-cost, principal investigator-led missions to the Red Planet. The Phoenix Mars Lander was the first spacecraft selected. Phoenix landed on the icy northern polar region of Mars on May 25, 2008. The spacecraft completed its prime science mission on Aug. 25, 2008. The mission has been extended through Sept. 30.
NASA's Mars Exploration Program seeks to characterize and understand Mars as a dynamic system, including its present and past environment, climate cycles, geology and biological potential.


NASA for the first time last week used microgravity research flights aboard commercially-owned aircraft to test hardware and technologies. These flights, on an airplane operated by the Zero Gravity Corporation, simulated the weightless conditions of space.

In addition to numerous NASA experiments, five companies sponsored by the agency's Innovative Partnerships Program flew experiments aboard the reduced-gravity aircraft flights from Ellington Field in Houston. The flights were the first in NASA's Facilitated Access to the Space Environment for Technology Development and Training program, called FAST.

The companies, which are participating in the Small Business Innovation Research program, tested five new technologies Sept. 9-10:

- Pneumatic mining under lunar gravity conditions (Honeybee Robotics of New York)
- Aircraft sensor-logger operations (Metis Design Corporation of Cambridge, Mass.)
- Microgravity flight testing of self-deploying shells (Mevicon Inc. of Sunnyvale, Calif.)
- Virtual sensor test instrumentation operations (Mobitrum Corporation of Silver Spring, Md.)
- Nanofluid coolant testing (nanoComposix, Inc. of San Diego, Calif.)

Representatives of the companies were aboard the aircraft to operate and evaluate their technologies during the flights, which created zero-gravity and lunar-gravity conditions. The technologies will improve air and space vehicle capabilities and support the design of systems for the exploration of the moon and operations there.

NASA's contract with the Zero Gravity Corporation of Las Vegas, which is managed by NASA's Glenn Research Center in Cleveland, is part of an effort to expand the agency's use of commercial services. The flights were conducted from Ellington Field with the nearby Johnson Space Center in Houston providing technical support to the participating experimenters

Weightless conditions are achieved by flying an airplane on a parabolic trajectory. A typical flight lasting two hours consists of 50 parabolas, generating up to 25 seconds of microgravity during each parabola.

Four days of flights originally were scheduled in September, but the approach of Hurricane Ike caused those scheduled Sept. 11-12 to be suspended. An effort will be made to reschedule the flights in the future. NASA's first flights with the Zero Gravity Corporation occurred the week of Aug. 25. More flights are planned in October, November and January.

A call for new proposals for FAST program flights in 2009 will be issued later this month. It will be open to any companies or organizations working on technologies of value to NASA.

Arctic Sea Ice Reaches Lowest Coverage for 2008

Arctic sea ice coverage appears to have reached its lowest extent for the year and the second-lowest amount recorded since the dawn of the satellite era, according to observations from the NASA-supported National Snow and Ice Data Center at the University of Colorado in Boulder.

While slightly above the record-low minimum set Sept. 16, 2007, this season further reinforces the strong negative trend in summer sea ice extent observed during the past 30 years. Before last year, the previous record low for September was 2005.

In March, when the Arctic reached its annual maximum sea ice coverage during the winter, scientists from NASA and the data center reported that thick, older sea ice was continuing to decline. According to NASA-processed satellite microwave data, this perennial ice used to cover 50-60 percent of the Arctic, but this winter it covered less than 30 percent. Perennial sea ice is the long-lived layer of ice that remains even when the surrounding short-lived seasonal sea ice melts to its minimum extent during the summer.

NASA scientists have been observing Arctic sea ice cover since 1979. NASA developed the capability to observe the extent and concentration of sea ice from space using passive microwave sensors.

The National Snow and Ice Data Center will issue an analysis of the possible causes behind this year's Arctic sea ice conditions during the first week of October. For updates, visit


Engineers at NASA's Marshall Space Flight Center in Huntsville, Ala., have completed first-round testing of a critical motor for NASA's new Ares I rocket. The Ares I is a two-stage rocket that will launch astronauts aboard the Orion crew capsule on missions to the International Space Station and to the moon by 2020.

The ullage settling motor is a small, solid rocket motor that serves two key roles during the launch of the Ares I rocket. During first stage separation, which occurs 125.8 seconds into flight, the motor will fire for four seconds, producing the forward thrust needed to push the second, or upper, stage away from the first stage. This forward thrust also ensures the rocket's liquid fuel is properly pushed to the bottom of the upper stage fuel tank prior to ignition of the J-2X engine that powers the upper stage.

The successful hot-fire test of this new development motor -- the first test in this series -- was conducted Sept. 11 at Marshall. All test objectives were achieved, bringing NASA one step closer to developing America's new space transportation system. This first series of early development testing will consist of four motors. It is scheduled to run through 2009. The second test series is planned for February 2009.

"We are extremely excited about the success of this test that proves we are headed down the correct development path for this program," said Danny Davis, upper stage manager for Ares Projects at Marshall. "We have the right team in place, and we are working a design that will secure America's future in space."

The word "ullage" is taken from the French term "ouillage," which is used in winemaking to describe the space between wine and the top of a storage container, such as a barrel or bottle. In this case, it refers to the space at the top of the first stage fuel tank and the need to push the fuel, or settle it, to the bottom of the tank.

The ullage motor, 9 inches in diameter and 47 inches in length, is similar in design to the booster separation motor used on the space shuttle's reusable solid rocket motor. Eight ullage motors will be arranged in four pairs on the Ares I upper stage aft skirt, which also houses the reaction control system. The aft skirt is located between the upper stage core, which contains the liquid hydrogen and oxygen fuel tanks, and the interstage, which houses the rocket's roll control system.

"We are very excited about this opportunity for our team to practice the basic principles of solid rocket motor design for the Ares I," said Steve Harvison, ullage settling motor design lead at Marshall. "It has been especially beneficial to newer team members who are fresh out of college and eager for this challenge. We are working every engineering aspect of these motors, from technical analysis, modeling and simulations to propellant tailoring work and hands-on developmental testing."

The first Ares I test flight, called Ares I-X, is scheduled for 2009.

NASA's Johnson Space Center in Houston manages the Constellation Program, which includes the Ares I rocket, the Ares V heavy-lift launch vehicle, the Orion crew capsule and the Altair lunar lander. Marshall manages the Ares Projects.

Video of the ullage motor test will be available Friday, Sept. 12, on NASA Television's Video File. For NASA TV downlink, schedule and streaming video information, visit:
