Technology News from Kennedy Space Center

Technology News : The seven-member crew of Atlantis are packing the orbiter and preparing to return home, wrapping up the 31st shuttle flight to the International Space Station. Atlantis is scheduled to land at 9:44 a.m. EST Friday at Kennedy Space Center in Florida.

Commander Charlie Hobaugh and Pilot Barry Wilmore, with help from Mission Specialist Randy Bresnik, will check out Atlantis' flight control surfaces, including the rudder and the wing flaps. Those surfaces will guide Atlantis’ unpowered flight through the atmosphere to a landing. The astronauts also will test fire reaction control system thrusters. The thrusters will control the shuttle’s orientation as it descends and begins its re-entry through the atmosphere.

A recumbent seat for Mission Specialist Nicole Stott will be setup on the shuttle's mid-deck. Stott is returning after 90 days in space, 80 as a station crewmember.

Tuesday at 10 a.m., European Space Agency astronaut Frank De Winne handed over command of the station to NASA astronaut Jeff Williams. De Winne and Expedition 21 Flight Engineers Roman Romanenko and Robert Thirsk are scheduled to leave the station for return to Earth in a Soyuz capsule on Nov. 30.

NASA Provides Venerable Hubble Hardware to Smithsonian

Two key instruments from NASA's Hubble Space Telescope have a new home in the Smithsonian's National Air and Space Museum in Washington after being returned to Earth aboard space shuttle Atlantis last May.

Astronauts brought back the Wide Field and Planetary Camera 2, or WFPC-2, and the Corrective Optics Space Telescope Axial Replacement, or COSTAR, after more than 15 years in space. The camera returned the iconic images that now adorn posters, album covers, the Internet, classrooms and science text books worldwide.

"This was the camera that saved Hubble," said Ed Weiler, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. "I have looked forward for a long time to stand in front of this very instrument while on display to the public."

After Hubble's launch and deployment aboard the shuttle in 1990, scientists realized the telescope's primary mirror had a flaw, known as a spherical aberration. The outer edge of the mirror was ground too flat by a depth of 2.2 microns, roughly equal to one-fiftieth the thickness of a human hair. This tiny flaw resulted in fuzzy images because some of the light from the objects being studied was scattered.

Hubble's first servicing mission provided the telescope with hardware that basically acted as eye glasses. Launched in December 1993 aboard space shuttle Endeavour, the mission added the WFPC-2, about the size of a baby grand piano, and COSTAR, about the size of a telephone booth. The WFPC-2 had the optical fix built in, while the COSTAR provided the optical correction for other Hubble instruments.

The WFPC-2 made more than 135,000 observations of celestial objects from 1993 to 2009. The camera was the longest serving and most prolific instrument aboard Hubble.

"For years the Wide Field and Planetary Camera 2 has been taking pictures of the universe," said John Trauger of NASA's Jet Propulsion Laboratory in Pasadena, Calif. "Today, we are taking pictures of the WFPC-2 and I guess if there was ever a camera that deserves to have its picture taken, this is it."

The Hubble instruments will be on display in the National Air and Space Museum's Space Hall through mid-December. They then will travel to Southern California to go on temporary display at several venues. In March 2010, the instruments will return to the Smithsonian Air and Space Museum, where they will take up permanent residency.

NASA's Jet Propulsion Laboratory designed and built the WFPC-2. The COSTAR instrument was built by Ball Aerospace in Boulder, Colo. The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. The project is managed by NASA's Goddard Space Flight Center in Greenbelt, Md. The Space Telescope Science Institute in Baltimore conducts Hubble science operations. The institute is operated for NASA by the Association of Universities for Research in Astronomy Inc., in Washington.

Space Shuttle Pilot Set to Talk With Tennessee Students from Orbit

Congressman Bart Gordon and Tennessee Technological University in Cookeville will host a live conversation between more than 120 students and NASA astronaut Barry E. Wilmore on Sunday, Nov. 22. Wilmore is the pilot of space shuttle Atlantis, which launched Nov. 16 on an 11-day mission to the International Space Station. Members of Wilmore's family also will attend the event.

The live call from orbit will take place between 11:08 a.m. and 11:28 a.m. CST. Twenty students, ranging from kindergarten to college age, will ask questions of Wilmore and fellow astronauts Nicole Stott and Leland Melvin. Stott has served as a flight engineer and member of the Expedition 21 crew living aboard the International Space Station for more than two months. She will return to Earth aboard Atlantis. Melvin is a mission specialist and crewmate of Wilmore's aboard Atlantis.

Reporters interested in attending the event should contact Monica Greppin at 931-372-3214. Gordon is the chairman of the House Science and Technology Committee. Wilmore was born and raised in Gordon's district in Tennessee and earned bachelor's and master's degrees in electrical engineering from Tennessee Technological University.

The downlink is one in a series with educational organizations in the U.S. and abroad to improve teaching and learning in science, technology, engineering and mathematics. It is an integral component of NASAs Teaching From Space office. The office promotes learning opportunities and builds partnerships with the education community using the unique environment of human spaceflight.

Earhart's Scarf to Fly Again

A scarf belonging to famed aviatrix Amelia Earhart will circle the Earth repeatedly as part of the personal cargo being carried into space by the astronauts of space shuttle Atlantis’ STS-129 mission.

Albert Bresnick was a personal photographer to Earhart, and now, astronaut Randy Bresnick is rekindling the family connection. The Marine aviator and first-time space flier received the white, green and red scarf from the 99s Museum of Women Pilots in Oklahoma City, an organization of female pilots that formed with the help of Earhart. Randy Bresnick is also bringing along a photo from the Amelia Earhart Birthplace Museum in Atchison, Kan.

In 1932, Earhart became the first woman to fly solo across the Atlantic Ocean, becoming in the process a prominent and celebrated adventurer. She, along with her navigator, disappeared over the Pacific Ocean five years later while trying to become the first woman to circumnavigate the globe in an airplane.

The remaining crew members of STS-129 have chosen a wide assortment of medals, shirts, patches and even a thumb drive to commemorate their 11-day venture to the International Space Station.

A cycling jersey from Lance Armstrong's LiveStrong Foundation will travel on the flight, completing the distance in seven minutes that Armstrong and the cyclists in the peloton rode in three weeks during the Tour de France.

Veteran astronaut Charles O. Hobaugh, also a Marine pilot, commands the mission that will deliver a pair of racks loaded with equipment to the station.

First-time shuttle Pilot Barry E. Wilmore has seen to it that Tennessee Technical University is well-represented in the commemorative assortment known as the Official Flight Kit. The school, which Wilmore graduated from with a master's in electrical engineering, will see a thumb drive, purple and gold placard, gold medallion, and a stuffed-toy eagle make the trip into space aboard space shuttle Atlantis.

The toy eagle will be joined by a stuffed-toy blue spider from the University of Richmond, the alma mater of veteran Mission Specialist Leland Melvin. A football jersey from Melvin's Heritage High School days also will make the trip. Melvin was drafted in 1986 by the NFL's Detroit Lions and took part in training camps with the Dallas Cowboys and Canadian Football League's Toronto Argonauts.

NASA Technology Spinoffs Art Contest

NASA Goddard Space Flight Center in Greenbelt, Md. is recognizing award-winning artwork honoring NASA Spinoff technology that was used to restore the Statue of Liberty National Monument, a unit of the National Park Service.

Students are recognizing NASA Goddard's 50th anniversary by reflecting on science, technology, engineering and the fine arts. NASA Goddard was opened in 1959.

NASA's Innovative Partnerships Program (IPP) Office sponsored "Goddard Celebrates 50 Years of Technology Spinoffs Art Contest" last winter. The purpose of the contest was to allow middle and high school students across the country to demonstrate through art, their knowledge of how NASA Goddard scientific technological achievements have made impacts on the quality of life. Some of the reference or source material the students were to use was the IPP Office annual publication, NASA Spinoff magazine, and the IPP Office website.

After receiving and reviewing contest submissions, Ja Hyun "Ashely" Lim was chosen as the winner. At the time of contest submission, she was a ninth grader at North County High School in Glen Burnie, Md. Lim's eloquent rendering of a paint brush stroke from the Space Shuttle's lift off pad launch gantries to the Statute of Liberty monument plainly demonstrates "movement" of NASA technology from one application of a technology to another external to NASA.

The connection between the Statue of Liberty and NASA is in a NASA Goddard-developed technology. When the Statue of Liberty was being restored in the early 1980s, the bars that help to support the copper skin of the Statue of Liberty were covered with a corrosion-resistant coating developed by NASA Goddard engineers. The coating is known as IC531, and is an aerospace Spinoff product manufactured by Inorganic Coatings, Inc. of Malvern, Penn.

IC531 was used as an interior structure primer coating for Miss Liberty. The coating was developed by NASA Goddard to protect gantries and other structures at NASA's Kennedy Space Center, Fla. launch site.

The high-ratio silicate formulation in IC531 bonds to steel and in just 30 minutes and creates a very hard ceramic finish with superior adhesion and abrasion resistance.

Lim was honored at the NASA Goddard Celebrates 50 Years of Technology Spinoffs Event this past summer. In the spirit of cooperation, the NASA Goddard IPP will be presenting a framed copy of Lim's artwork to the National Park Service at the Statue of Liberty on Nov. 13 at 9:30 a.m. EST at Ellis Island, N.Y.

Located on a 12-acre island, the statue of ‘Liberty Enlightening the World' was a gift of friendship from the people of France to the people of the United States and is a universal symbol of freedom and democracy.

Scientists Discover Record Fifth Planet Orbiting Nearby Star

Astronomers have announced the discovery of a fifth planet circling 55 Cancri, a star beyond our solar system. The star now holds the record for number of confirmed extrasolar planets orbiting in a planetary system.

55 Cancri is located 41 light-years away in the constellation Cancer and has nearly the same mass and age as our sun. It is easily visible with binoculars. Researchers discovered the fifth planet using the Doppler technique, in which a planet's gravitational tug is detected by the wobble it produces in the parent star. NASA and the National Science Foundation funded the research.

"It is amazing to see our ability to detect extrasolar planets growing," said Alan Stern, associate administrator for the Science Mission Directorate at NASA Headquarters, Washington. "We are finding solar systems with a richness of planets and a variety of planetary types comparable to our own."

The newly discovered planet weighs about 45 times the mass of Earth and may be similar to Saturn in its composition and appearance. The planet is the fourth from 55 Cancri and completes one orbit every 260 days. Its location places the planet in the "habitable zone," a band around the star where the temperature would permit liquid water to pool on solid surfaces. The distance from its star is approximately 116.7 million kilometers (72.5 million miles), slightly closer than Earth to our sun, but it orbits a star that is slightly fainter.

LCROSS Impact Data Indicates Water on Moon

The argument that the moon is a dry, desolate place no longer holds water. Secrets the moon has been holding, for perhaps billions of years, are now being revealed to the delight of scientists and space enthusiasts alike.

NASA today opened a new chapter in our understanding of the moon. Preliminary data from the Lunar CRater Observation and Sensing Satellite, or LCROSS, indicates that the mission successfully uncovered water during the Oct. 9, 2009 impacts into the permanently shadowed region of Cabeus cater near the moon's south pole.

The impact created by the LCROSS Centaur upper stage rocket created a two-part plume of material from the bottom of the crater. The first part was a high angle plume of vapor and fine dust and the second a lower angle ejecta curtain of heavier material. This material has not seen sunlight in billions of years.

"We're unlocking the mysteries of our nearest neighbor and by extension the solar system. It turns out the moon harbors many secrets, and LCROSS has added a new layer to our understanding," said Michael Wargo, chief lunar scientist at NASA Headquarters in Washington.

Scientists have long speculated about the source of vast quantities of hydrogen that have been observed at the lunar poles. The LCROSS findings are shedding new light on the question of water, which could be more widespread and in greater quantity than previously suspected.

Permanently shadowed regions could hold a key to the history and evolution of the solar system, much as an ice core sample taken on Earth reveals ancient data. In addition, water, and other compounds represent potential resources that could sustain future lunar exploration.

Since the impacts, the LCROSS science team has been working almost nonstop analyzing the huge amount of data the spacecraft collected. The team concentrated on data from the satellite's spectrometers, which provide the most definitive information about the presence of water. A spectrometer examines light emitted or absorbed by materials that helps identify their composition.

"We are ecstatic," said Anthony Colaprete, LCROSS project scientist and principal investigator at NASA's Ames Research Center in Moffett Field, Calif. "Multiple lines of evidence show water was present in both the high angle vapor plume and the ejecta curtain created by the LCROSS Centaur impact. The concentration and distribution of water and other substances requires further analysis, but it is safe to say Cabeus holds water."

The team took the known near infrared spectral signatures of water and other materials and compared them to the spectra collected by the LCROSS near infrared spectrometer of the impact.

Robot Armada Might Scale New Worlds

An armada of robots may one day fly above the mountain tops of Saturn's moon Titan, cross its vast dunes and sail in its liquid lakes. Wolfgang Fink, visiting associate in physics at the California Institute of Technology in Pasadena says we are on the brink of a great paradigm shift in planetary exploration, and the next round of robotic explorers will be nothing like what we see today.

"The way we explore tomorrow will be unlike any cup of tea we've ever tasted," said Fink, who was recently appointed as the Edward and Maria Keonjian Distinguished Professor in Microelectronics at the University of Arizona, Tucson. "We are departing from traditional approaches of a single robotic spacecraft with no redundancy that is Earth-commanded to one that allows for having multiple, expendable low-cost robots that can command themselves or other robots at various locations at the same time."

Fink and his team members at Caltech, the U.S. Geological Survey and the University of Arizona are developing autonomous software and have built a robotic test bed that can mimic a field geologist or astronaut, capable of working independently and as part of a larger team. This software will allow a robot to think on its own, identify problems and possible hazards, determine areas of interest and prioritize targets for a close-up look.

The way things work now, engineers command a rover or spacecraft to carry out certain tasks and then wait for them to be executed. They have little or no flexibility in changing their game plan as events unfold; for example, to image a landslide or cryovolcanic eruption as it happens, or investigate a methane outgassing event.

"In the future, multiple robots will be in the driver's seat," Fink said. These robots would share information in almost real time. This type of exploration may one day be used on a mission to Titan, Mars and other planetary bodies. Current proposals for Titan would use an orbiter, an air balloon and rovers or lake landers.

In this mission scenario, an orbiter would circle Titan with a global view of the moon, with an air balloon or airship floating overhead to provide a birds-eye view of mountain ranges, lakes and canyons. On the ground, a rover or lake lander would explore the moon's nooks and crannies. The orbiter would "speak" directly to the air balloon and command it to fly over a certain region for a closer look. This aerial balloon would be in contact with several small rovers on the ground and command them to move to areas identified from overhead.

"This type of exploration is referred to as tier-scalable reconnaissance," said Fink. "It's sort of like commanding a small army of robots operating in space, in the air and on the ground simultaneously."

A rover might report that it's seeing smooth rocks in the local vicinity, while the airship or orbiter could confirm that indeed the rover is in a dry riverbed - unlike current missions, which focus only on a global view from far above but can't provide information on a local scale to tell the rover that indeed it is sitting in the middle of dry riverbed.

A current example of this type of exploration can best be seen at Mars with the communications relay between the rovers and orbiting spacecraft like the Mars Reconnaissance Orbiter. However, that information is just relayed and not shared amongst the spacecraft or used to directly control them.

"We are basically heading toward making robots that command other robots," said Fink, who is director of Caltech's Visual and Autonomous Exploration Systems Research Laboratory, where this work has taken place.

"One day an entire fleet of robots will be autonomously commanded at once. This armada of robots will be our eyes, ears, arms and legs in space, in the air, and on the ground, capable of responding to their environment without us, to explore and embrace the unknown," he added.

Papers describing this new exploration are published in the journal "Computer Methods and Programs in Biomedicine" and in the Proceedings of the SPIE.
