Refurbishment on Grand Scale for Iconic VAB

 Iconic VAB

The Vehicle Assembly Building at NASA's Kennedy Space Center in Florida has been a landmark to the technological advancements of sending men to the moon and astronauts into space for more than 45 years. But the VAB, as it is best known, is due for major renovations to continue processing launch vehicles and support the subsequent launching of a new generation of astronauts into orbit and deeper into space than ever before.

"This is home improvement, VAB style," said Jose Lopez, who is managing the effort to refurbish a structure that was once the biggest in the world. "We're going for more flexibility and reliability with modern equipment. That building has many systems that haven't been touched up since it was built (in 1965)."

Although the work is massive simply because of the scale of the VAB, Lopez said now is the time to do it and take advantage of the pause in rocket processing that is to end in a couple years. Before another generation of rocket processing kicks in, Lopez said, the VAB must be outfitted with everything it needs to host these rockets and spacecraft assembly for another 40 years.


NASA Conducts Orion Parachute Testing for Orbital Test Flight

Orion Parachute Testing

NASA successfully conducted a drop test of the Orion crew vehicle's parachutes high above the Arizona desert Tuesday, Dec. 20, in preparation for its orbital flight test in 2014. Orion will carry astronauts deeper into space than ever before, provide emergency abort capability, sustain the crew during space travel and ensure a safe re-entry and landing.

A C-130 plane dropped the Orion test article from an altitude of 25,000 feet above the U.S. Army's Yuma Proving Grounds. Orion's drogue chutes were deployed between 15,000 and 20,000 feet, followed by the pilot parachutes, which then deployed two main landing parachutes. This particular drop test examined how Orion would land under two possible failure scenarios.

Orion's parachutes are designed to open in stages which are called reefing, to manage the stresses on the parachutes after they are deployed. The reefing stages allow the parachutes to sequentially open, first at 54 percent of the parachutes' full diameter, and then at 73 percent. This test examined how the parachutes would perform if the second part of the sequence was skipped.

NASA Mars-Bound Rover Begins Research in Space


NASA's car-sized Curiosity rover has begun monitoring space radiation during its 8-month trip from Earth to Mars. The research will aid in planning for future human missions to the Red Planet. Curiosity launched on Nov. 26 from Cape Canaveral, Fla., aboard the Mars Science Laboratory. The rover carries an instrument called the Radiation Assessment Detector (RAD) that monitors high-energy atomic and subatomic particles from the sun, distant supernovas and other sources.

These particles constitute radiation that could be harmful to any microbes or astronauts in space or on Mars. The rover also will monitor radiation on the surface of Mars after its August 2012 landing. "RAD is serving as a proxy for an astronaut inside a spacecraft on the way to Mars," said Don Hassler, RAD's principal investigator from the Southwest Research Institute in Boulder, Colo. "The instrument is deep inside the spacecraft, the way an astronaut would be. Understanding the effects of the spacecraft on the radiation field will be valuable in designing craft for astronauts to travel to Mars."

Previous monitoring of energetic-particle radiation in space has used instruments at or near the surface of various spacecraft. The RAD instrument is on the rover inside the spacecraft and shielded by other components of Mars Science Laboratory, including the aeroshell that will protect the rover during descent through the upper atmosphere of Mars. Spacecraft structures, while providing shielding, also can contribute to secondary particles generated when high-energy particles strike the spacecraft. In some circumstances, secondary particles could be more hazardous than primary ones

"Coming Back Down to our Fragile Oasis," featuring Peter Gabriel's "Down to Earth"

 Fragile Oasis
A time-lapse video is about as close as we can come to show what astronauts see in space. This time-lapse video is a collaboration between images taken by Ron Garan and Mike Fossum from the International Space Station and music from Peter Gabriel. The music featured in the video is Peter Gabriel's "Down to Earth".

All of the sequences for this video were shot by either Mike Fossum or Ron Garan. Although the International Space Station travels at 17,500 mph, orbiting the Earth every 90 minutes, time-lapse photography speeds up the apparent motion considerably.

The flashes of lightning throughout the video are captured by the individual frames of the photography. Yet, only a small percentage of the actual lightning is captured in the imagery. While the video is sped up, it still accurately captures the paparazzi-look of lightening storms as we see them from space. While still onboard the ISS, Peter Gabriel and Ron Garan brainstormed some ideas for using this type of imagery to help tell the Fragile Oasis story. The hope with this video and others like it is to help people follow the missions not as spectators, but as crewmembers, inspired to help improve life on our planet.


What Goes Up Must Come Down

Must Come Down

NASA's Langley Research Center completed another successful test of the Orion spacecraft's landing capabilities in their Hydro Impact Basin.While workers prepared the 18,000-pound (8,165 kg) Orion Multi-Purpose Crew Vehicle to take a dive into the 115-feet-long, 90-feet-wide, 20-feet-deep water basin (35.1 x 27.4 x 6.1 meters), media sat inside a conference room overlooking the action.

Langley offered experts to explain the process and importance of the test."It was the second in a series of six that would help predict conditions for a safe water landing," said Dave Bowles, the head of Langley's Space Exploration Directorate.

Following this round of testing, a new Orion capsule will be delivered to Langley for another series of tests that will capture additional data using sensors. The new vehicle more closely resembles the capsule that will eventually carry astronauts into space.
 

Desert RATS 2011: Mid-way Report

Mid-way Report

NASA's Desert Research and Technology Studies (Desert RATS) crew has reached the mid-way point in the 14th annual Desert RATS mission, conducted at Black Point Lava Flow in the Arizona desert. On Aug. 30, the crew consisting of engineers, astronauts, scientists, and technicians from across NASA and throughout industry and academia began integrated mission simulations to evaluate different conditions that will enable human and robotic exploration of an asteroid.

So far, much of the testing has focused on crew operations inside of the Deep Space Habitat (DSH). For three nights each, Crew A and Crew B slept overnight in the DSH to test independent crew operations and the habitability of the xHab Loft and Hygiene Module. Testing these elements is crucial for understanding what logistics and living quarter’s humans will need during deep-space exploration missions.

The Desert RATS crew has also successfully tested communication links through the European Science and Technology Centre (ESTEC). With primary science backroom support from mission control in Houston, the ESTEC provided secondary science backroom operations support from the Netherlands.

Calling the Caribbean from the International Space Station

 International Space Station

Close to 300 students in the Caribbean got a very long distance call from the International Space Station on Monday, Aug. 8, 2011. Crew members aboard the station used the Amateur Radio on the International Space Station, or ARISS, to make contact with their eager audience on the ground. The goal was to inspire students and educators via an interactive space experience. This was the first ARISS communication for the Caribbean region.

The ARISS conversations usually last about 10 minutes. During that time, chosen students on the ground ask questions, which the crew answers from the space station. Questions during the Caribbean contact ranged from how space travel affects human health and how the space station was powered and maneuvered to concerns about space debris. Students also wanted to know what it was like to be an astronaut, asking about the most difficult aspects of the job.

Students prepared by learning about the space station, radio waves and how amateur radio works, as well as proposing questions to ask the crew. Ken Ransom, project coordinator with the International Space Station Ham Radio Program, points out the educational benefits of the approximately 50 conversations that take place every year. "The ARISS program is all about inspiring and encouraging by reaching the community and providing a chance for schools to interact with local technical experts. It also brings the space program to their front door."

Atlantis and Crew Land in Florida, Closing Out Shuttle Era

Atlantis and Crew Land in Florida

"It is great to have Atlantis safely home after a tremendously successful mission -- and home to stay," said Bob Cabana, Kennedy Space Center director, referencing Atlantis' retirement at Kennedy's Visitor Complex."I'm unbelievably proud to be here representing the Space Shuttle Program and the thousands of people across the country who do the work," said Mike Moses, space shuttle launch integration manager. "Hearing the sonic booms as Atlantis came home for the last time really drove it home to me that this has been a heck of a program."

"The workers out here and across the country in the Space Shuttle Program have dedicated their lives, their hearts and their souls to this program, and I couldn't be more proud of them," said Mike Leinbach, space shuttle launch director at Kennedy.A crew news conference with the STS-135 astronauts is scheduled for noon and will be carried live on NASA TV and online at www.nasa.gov/ntv. Atlantis landed at 5:57 a.m. EDT, after 200 orbits around Earth and a journey of 5,284,862 miles.

The STS-135 crew consisted of Commander Chris Ferguson, Pilot Doug Hurley, Mission Specialists Sandra Magnus and Rex Walheim. They delivered more than 9,400 pounds of spare parts, spare equipment and other supplies in the Raffaello multi-purpose logistics module - including 2,677 pounds of food - that will sustain space station operations for the next year. The 21-foot long, 15-foot diameter Raffaello brought back nearly 5,700 pounds of unneeded materials from the station.

Wakeup Music of the Space Shuttle’s Final Mission

Space Shuttle’s Final Mission

Use of music to awaken astronauts on space missions dates back at least to the Apollo Program, when astronauts returning from the moon were serenaded by their colleagues in mission control with lyrics from popular songs that seemed appropriate for the occasion.

Usually picked by flight controllers or by crew members’ friends and family members, most wakeup calls are musical, but sometimes include dialog from movies or TV shows. The playlist is eclectic, ranging from rock, country, classical, bluegrass and jazz, to children’s choruses and songs from the countries of international crewmembers. The recording is usually followed by a call from the CAPCOM in Mission Control, wishing the crew a good morning.

The common element of all these selections is that they promote a sense of camaraderie and esprit de corps among the astronauts and ground support personnel.

NASA Honors Pioneer Astronaut Alan Shepard With Moon Rock

http://nasa-satellites.blogspot.com/
NASA will posthumously honor Alan B. Shepard Jr., the first American astronaut in space who later walked on the moon, with an Ambassador of Exploration Award for his contributions to the U.S. space program. Shepard's family members will accept the award on his behalf during a ceremony at 5:30 p.m. EDT on Thursday, April 28, at the U.S. Naval Academy Museum, located at 74 Greenbury Point Road in Annapolis, Md. His family will present the award to the museum for permanent display. NASA's Chief Historian Bill Barry will represent the agency at the event, which will include a video message from NASA Administrator Charles Bolden.

Shepard, a 1945 graduate of the Naval Academy, was one of NASA's original seven Mercury astronauts selected in April 1959. On May 5, 1961, he was launched from Cape Canaveral, Fla., aboard the Freedom 7 spacecraft on a suborbital flight that carried him to an altitude of 116 miles. Shepard made his second spaceflight as the commander of Apollo 14 from Jan. 31 to Feb. 9, 1971. He was accompanied on the third lunar landing by astronauts Stuart Roosa and Edgar Mitchell. Maneuvering the lunar module "Antares" to a landing in the hilly upland Fra Mauro region of the moon, Shepard and Mitchell deployed and activated a number of scientific instruments and collected almost 100 pounds of lunar samples for return to Earth.

Reporters interested in covering the award ceremony must contact the Naval Academy's public affairs office at 410-293-2292 or mediarelations@usna.edu by noon, Wednesday, April 27, for access information. NASA is giving the Ambassador of Exploration Award to the first generation of explorers in the Mercury, Gemini and Apollo space programs for realizing America's goal of going to the moon. The award is a moon rock encased in Lucite, mounted for public display. The rock is part of the 842 pounds of lunar samples collected during six Apollo missions from 1969 to 1972. The astronauts or family members receiving the award present it to a museum of their choice, where the moon rock is placed on public display. 

NASA Awards Next Set Of Commercial Crew Development Agreements

http://nasa-satellites.blogspot.com/
NASA has awarded four Space Act Agreements in the second round of the agency's Commercial Crew Development (CCDev2) effort. Each company will receive between $22 million and $92.3 million to advance commercial crew space transportation system concepts and mature the design and development of elements of their systems, such as launch vehicles and spacecraft.

The selectees for CCDev2 awards are:
-- Blue Origin, Kent, Wash., $22 million
-- Sierra Nevada Corporation, Louisville, Colo., $80 million
-- Space Exploration Technologies (SpaceX), Hawthorne, Calif., $75 million
-- The Boeing Company, Houston, $92.3 million

"We're committed to safely transporting U.S. astronauts on American-made spacecraft and ending the outsourcing of this work to foreign governments," NASA Administrator Charles Bolden said. "These agreements are significant milestones in NASA's plans to take advantage of American ingenuity to get to low-Earth orbit, so we can concentrate our resources on deep space exploration." The goal of CCDev2 is to accelerate the availability of U.S. commercial crew transportation capabilities and reduce the gap in American human spaceflight capability. Through this activity, NASA also may be able to spur economic growth as potential new space markets are created.

Once developed, crew transportation capabilities could become available to commercial and government customers. "The next American-flagged vehicle to carry our astronauts into space is going to be a U.S. commercial provider," said Ed Mango, NASA's Commercial Crew Program manager. "The partnerships NASA is forming with industry will support the development of multiple American systems capable of providing future access to low-Earth orbit." 

Discovery’s last crew arrive at NASA’s Kennedy Space Center

http://nasa-satellites.blogspot.com/
Arriving in their trademark T-38 Talon jets, the crew that will fly the final mission of the space shuttle Discovery inwards at NASA’s Kennedy Space Center in Florida. The astronauts landed at the Shuttle Landing Facility (SLF) at 3:45 p.m. EDT and took a little moments to speak to members of the media and pose for pictures before heading off to train for their 11-day mission. Discovery is now slated to begin its mission to the International Space Station (ISS) with liftoff taking place at 4:50 p.m. EDT Thursday, Feb. 24. The STS-133 mission is Discovery’s last planned flight.

However, STS-132, which took place this past May, was shuttle Atlantis’ final planned flight now that orbiter is scheduled to close out the shuttle program when it whole mission STS-135, which is scheduled to take place late this summer. The crew will convey the Leonardo Permanent Multipurpose Module (PMM) to the space station. The PMM was customized from the Multi-Purpose Logistics Module (MPLM) Leonardo which was fundamentally a cargo container. Now, Leonardo will be a permanent fixture on the orbiting outpost given that additional storage for the station’s crew. On the way to orbit, the PMM will carry, among further things, the first human-like robot ever flown in space, Robonaut 2 (R2).

R2 will stay onboard the place and will be used to test the viability of related robots in assisting astronauts on future long-duration missions. One of the things that the station can forever use is more spare parts. STS-133 will deliver various division and the Express Logistics Carrier 4, a platform that holds great equipment. The crew consists of Commander Steve Lindsey, Pilot Eric Boe and Mission expert Alvin Drew, Steve Bowen, Michael Barratt and Nicole Stott. Bowen is a final minute addition to the crew.

A Race Against Time to Find Apollo 14's Lost Voyagers

http://nasa-satellites.blogspot.com/
In communities all across the U.S., travelers that went to the moon and back with the Apollo 14 mission are living out their quiet lives. The whereabouts of more than 50 are known. Many, now aging, reside in prime retirement locales: Florida, Arizona and California. A few are in the Washington, D.C., area. Hundreds more are out there or at least, they were. And Dave Williams of NASA's Goddard Space Flight Center in Greenbelt, Md., wants to find them before it's too late. The voyagers in question are not astronauts. They're "moon trees" redwood, loblolly pine, sycamore, Douglas fir, and sweetgum trees sprouted from seeds that astronaut Stuart Roosa took to the moon and back 40 years ago.

"Hundreds of moon trees were distributed as seedlings," says Williams, "but we don't have systematic records showing where they all went." And though some of the trees are long-lived species expected to live hundreds or thousands of years, others have started to succumb to the pressures of old age, severe weather and disease. At least a dozen have died, including the loblolly pine at the White House and a New Orleans pine that was damaged by Hurricane Katrina and later removed. To capture the vanishing historical record, Williams, a curator at the National Space Science Data Center, has been tracking down the trees, dead or alive.

His sleuthing started in 1996, prompted by an email from a third-grade teacher, Joan Goble, asking about a tree at the Camp Koch Girl Scout Camp in Cannelton, Ind. A simple sign nearby read "moon tree." "At the time, I had never heard of moon trees," Williams says. "The sign had a few clues, so I sent a message to the NASA history office and found more bits and pieces on the web. Then I got in touch with Stan Krugman and got more of the story." Krugman had been the U.S. Department of Agriculture Forest Service's staff director for forest genetics research in 1971. He had given the seeds to Roosa, who stowed them in his personal gear for the Apollo 14 mission. The seeds were symbolic for Roosa because he had fought wildfires as a smoke jumper before becoming an Air Force test pilot and then an astronaut

Astronaut Marsha Ivins Leaves NASA

http://nasa-satellites.blogspot.com/NASA astronaut Marsha Ivins, a veteran of five spaceflights, has retired from the agency. "Marsha's incredible depth of mission experience and technical expertise has been a tremendous asset to this office," said Peggy Whitson, chief of the Astronaut Office at NASA's Johnson Space Center in Houston. "We have relied on her expertise for years in many diverse areas, including but not limited to crew provisions, optimal hardware packing, human ratings development, vehicle habitability and orbiter preflight vehicle checks. Her expertise and dedication to NASA's mission will be sorely missed."

Ivins joined NASA in 1974 as an engineer. She worked on space shuttle displays, controls, man-machine engineering and the development of the orbiter's head-up display. She served in Johnson's aircraft operations as a flight engineer for the Shuttle Training Aircraft and copilot of the Gulfstream I. Ivins was selected as an astronaut in 1984. She spent more than 1,300 hours in space during five shuttle flights: STS-32 in 1990, STS-46 in 1992, STS-62 in 1994, STS-81 in 1997 and STS-98 in 2001. Ivins most recently worked within the Astronaut Office supporting the Space Shuttle, International Space Station and Constellation Programs.

Astronaut Alan Poindexter Leaves NASA


Veteran NASA astronaut Alan Poindexter has left the agency to return to the Naval Postgraduate School in Monterey, Calif. Poindexter, a U.S. Navy captain, earned a Master of Science degree in aeronautical engineering from the school in 1995. He will return to serve as the dean of students and executive director of programs. "Dex was a well-respected leader within our office," said Peggy Whitson, chief of the Astronaut Office at NASA's Johnson Space Center in Houston. "We will miss him being part of our team and wish him the best in his new role as he continues his service to the Navy and the country."

A veteran of two spaceflights, Poindexter logged more than 669 hours in space. In 2008, he was the pilot on the STS-122 space shuttle mission to deliver and install the European Space Agency's Columbus laboratory to the International Space Station. In 2010, he was the commander for STS-131, a resupply mission to the station that delivered more than 13,000 pounds of hardware and equipment. He was selected as an astronaut candidate in June 1998 and served in the Astronaut Office Shuttle Operations Branch as the lead support astronaut at NASA's Kennedy Space Center in Florida. He also served as a spacecraft communicator, or capcom, for several missions.

Hundreds Tour Kennedy on Two Wheels

http://nasa-satellites.blogspot.com/
Hundreds of bicyclists mingled with spacecraft Oct. 23 as Kennedy employees, family and guests pedaled around the center for the second Tour de KSC. Grouped by speed and skill levels, some riders covered all the landmarks Kennedy has to offer, including the Vehicle Assembly Building, both shuttle launch pads and the Shuttle Landing Facility. Plenty of stops along the way offered employees and their guests photo ops with space shuttle Discovery on Launch Pad 39A. In all, 681 people rode their bikes onto the space center for the event, said Dicksy Hansen, chair of Combined Federal Campaign or CFC. " We had a range of those employees who haven’t been on a bike for years up to very talented cyclists who cycle passionately," Hansen said.

"There were beach cruisers, recumbents, touring, and racing bikes. Some people were dressed in cycling gear and others dressed in regular, every day clothes. There was even an 18th Century style bicycle with a very large rear wheel and small front wheel. This made the event even more diverse and entertaining." The entry fee for each person included a donation to the CFC and organizers of this year's event were able to contribute $10,215 to the annual fundraising drive. Riders also received a T-shirt. "We increased our CFC donation from $5 to $15 a ticket which increased our donation from $2,500 last year to $10,000 this year," Hansen said. Center Director Bob Cabana, a former astronaut and avid cyclist, led a group out from the Kennedy Space Center Visitor Complex then up to the VAB.

"I believe that there is a variety of reasons folks come out," Hansen said. "Some because they love cycling and KSC so it is a great day for them when the two come together. Other folks just enjoy coming out to KSC and bringing their guests to view the Center. There aren’t very many opportunities for employees to bring guests on Center. Others wanted to support CFC and contribute by enjoying a few hours cycling around the Center." Last year's inaugural event also opened the CFC season. This was the second Tour de KSC, but will not be the last, Hansen said. Each event takes considerable planning and Hansen's group already anticipates holding the third event next year. 

LRO Supports Historic Lunar Impact Mission

http://nasa-satellites.blogspot.com/
The lunar rocks brought back to the Earth by the Apollo astronauts were found to have very little water, and to be much drier than rocks on Earth. An explanation for this was that the Moon formed billions of years ago in the solar system's turbulent youth, when a Mars-sized planet crashed into Earth. The impact stripped away our planet's outer layer, sending it into orbit. The pieces later coalesced under their own gravity to form our Moon. Heat from all this mayhem vaporized most of the water in the lunar material, so the water was lost to space.

However, there was still a chance that water might be found in special places on the Moon. Due to the Moon's orientation to the Sun, scientists theorized that deep craters at the lunar poles would be in permanent shadow and thus extremely cold and able to trap volatile material like water as ice perhaps delivered there by comet impacts or chemical reactions with hydrogen carried by the solar wind. Last year on October 9, NASA's LCROSS intentionally crashed its companion Centaur upper stage into the Cabeus crater near the lunar south pole. The idea was to kick up debris from the bottom of the crater so its composition could be analyzed. The Centaur hit at over 5,600 miles per hour, sending up a plume of material over 12 miles high.

"Seeing mostly pure water ice grains in the plume means water ice was somehow delivered or chemical processes are causing ice to accumulate in large quantities," said Anthony Colaprete, LCROSS project scientist and principal investigator at NASA's Ames Research Center, Moffett Field, Calif. "Furthermore, the diversity and abundance of certain materials called volatiles in the plume, suggest a variety of sources, like comets and asteroids, and an active water cycle within the lunar shadows." LCROSS was a companion mission to NASA's Lunar Reconnaissance Orbiter (LRO) mission.

NASA Wants Student Innovators For 2011 Great Moonbuggy Race

http://nasa-satellites.blogspot.com/
Four decades after the first NASA lunar rover rolled across the surface of the moon, innovative students are preparing to design and build a new generation of wheeled wonders. Registration is open for the 18th annual NASA Great Moonbuggy Race, set for April 1-2, 2011, in Huntsville, Ala. Participating schools and institutions may register one or two vehicles and teams. Registration closes Feb. 1. NASA's Marshall Space Flight Center organizes the races held at the U.S. Space & Rocket Center, both in Huntsville. The event challenges high school and college students to design, build and race lightweight, human-powered "moonbuggies."

The first rover was developed, built and tested at Marshall in just 17 months. The rover's inaugural trip across the moon's surface took place on July 31, 1971. It was driven by Apollo 15 astronauts David Scott and James Irwin. Two more rovers followed, enabling expanded scientific exploration during the Apollo 16 and 17 missions in 1972. NASA Great Moonbuggy Race teams carry on the tradition of engineering ingenuity. The teams attempt to post the fastest vehicle assembly and race times in their divisions, while incurring the fewest penalties on a challenging course simulating the rocky, unforgiving surface of the moon.

Prizes are awarded to the three teams in each division that finish with the fastest race times. NASA and industry sponsors present additional awards for team spirit, best newcomer, most memorable buggy wipeout and other achievements. In 2010, for the first time, the victors in the high school and college divisions were both from outside the continental United States. The International Space Education Institute of Leipzig, Germany, raced to a winning time of just 3 minutes, 37 seconds in the high school category. The University of Puerto Rico in Humacao, the only school to enter a moonbuggy every year since the races began in 1994, won the college division with a time of 4 minutes, 18 seconds.

NASA and Gowalla Launch Partnership With Search for Moon Rocks

http://nasa-satellites.blogspot.com/
NASA and Gowalla are bringing people one small step closer to the universe. Anyone who uses Gowalla, a mobile and web service, now has the opportunity to find and collect four NASA-related virtual items a moon rock, a NASA patch, a spacesuit and a space shuttle. Gowalla's mission is to inspire discovery by connecting people with the places around them. When Gowalla users virtually "check-in" at NASA-related venues via their iPhone, Blackberry, Android, Palm or iPad, they now have a chance to find one of the four items.

Virtual moon rocks can be found when Gowalla users check in to any location where a real one is on display. The United States successfully brought lunar samples back to Earth during the Apollo 11, 12, 14, 15, 16, and 17 missions. NASA provides a number of these moon rocks for display and public viewing at museums, planetariums and scientific expositions around the world. To help people find the lunar samples, Gowalla and JESS3, a creative agency that specializes in data visualization, created a special edition NASA+Gowalla Map: Search for the Moon Rocks.

Gowalla users can find the virtual NASA patch, spacesuit and space shuttles by checking in to NASA visitor centers, agency-related locations, or one of the more than 400 museums, science centers, planetariums, observatories, parks, nature centers, zoos and aquariums that are part of NASA's Museum Alliance. The partnership also enables a NASA account on Gowalla and an account for astronaut Mike Massimino, both linked to their respective Twitter accounts, @NASA, and @Astro_Mike. NASA and Massimino also will drop virtual items for users to find and collect throughout the nation. Anyone with a Gowalla account who collects three of the four items will receive a special pin in their Gowalla Passport. In addition, the first 100 people to collect three items will receive a poster of the map in the mail.

NASA Selects Astronaut Leland D. Melvin to Lead Office of Education

http://nasa-satellites.blogspot.com/NASA Administrator Charles Bolden announced Tuesday the selection of Leland D. Melvin as the agency's new associate administrator for education, effective immediately. He succeeds James L. Stofan, who had served in an acting capacity since the spring. Since April 2010, Melvin has been assigned to the Office of Education at Headquarters leading the Education Design Team. His job was to develop a strategy to improve NASA's education offerings and to assist the agency in establishing goals, structures, processes and evaluation techniques to implement a sustainable and innovative science, technology, engineering and math (STEM) education program. He also served as the partnership development manager for the agency's new Summer of Innovation education initiative, aimed at engaging middle school students in STEM activities during the summer break.

"I am delighted to have Leland lead the Office of Education at a time when engaging more students in STEM-related studies and careers is so critical not only to NASA but to our nation," Bolden said. "With his dedication and passion, I know we will have a bright future in education under his leadership." "I also want to thank Jim Stofan for the outstanding job he has done leading the Office of Education since April," Bolden added. "He launched several key new education programs during his tenure and will continue to be a valued asset as he resumes his previous role as deputy associate administrator."

As associate administrator, Melvin will be responsible for the development and implementation of the agency's education programs that strengthen student involvement and public awareness about NASA's scientific goals and missions. "My passion for education was inspired by my parents, who were both middle school teachers," Melvin said. "I witnessed the direct impact that educators can have in a community and on an individual's destiny. NASA's people, programs and resources are unparalleled. Our unique assets are poised to engage students, to captivate their imagination and to encourage their pursuit of STEM-related studies that are so vital to their future. This is an exciting challenge and I am ready to work with Administrator Bolden, my colleagues at NASA, our partners, and students across the country to usher in a new era of opportunity to inspire that next generation of explorers."
