“Red and Rover” pay tribute to the space shuttle program, racing alongside the space shuttle as it lands for the final time later this year. Cartoonist and space exploration supporter Brian Basset created this commemorative drawing for NASA, to honor the shuttles. A poster commemorating the program’s 30th anniversary will feature Basset’s cartoon and a patch selected as part of a contest among NASA employees to honor the program.
“The U.S. space program has been the one constant throughout my entire life,” Basset said. “I was humbled and honored when given the opportunity to create the art for the commemorative Space Shuttle Program 30th anniversary poster.”
“Red and Rover” is a great cartoon series about the unconditional love between a boy and his dog. The two often dream of going to space together. But it won’t be on a space shuttle.

‘In Flight’ …. That’s the heart of the dramatic plan to showcase a Space Shuttle Orbiter being proposed by the Kennedy Space Center Visitor Complex (KSCVC) as they seek to win the heated competition to become the permanent new home to one of NASA’s three soon to be retiredOrbiters.
Honoring the past, embracing the future of human spaceflight and celebrating the spirit of human determination; this is the new theme planned by the Visitor Complex at Kennedy so that guests of all ages will feel like they are embarking on an interactive space expedition. See the ‘In Flight’ graphic illustration above.
Some 21 science centers and museums across the US are bidding for the once in a lifetime chance to house NASA’s surviving shuttle orbiters; Discovery, Atlantis and Endeavour.
“The Kennedy Space Center is the home of the Space Shuttle unlike all the other places,” said Bill Moore, Chief Operating Officer of KSCVC. I spoke to Moore at KSC in an exclusive interview for Universe Today.
“All of the shuttle missions have launched from here, not anywhere else. So Kennedy is their home. And they all eventually come back here at the end of each mission. So we have a compelling story to tell about their history at KSC and the future.”

The Smithsonian National Air & Space Museum, Washington, D.C., has long been expected to be picked as the retirement home for Space Shuttle Discovery, the oldest orbiter. That leaves Atlantis and Endeavour remaining in the bidding war. Since the Smithsonian currently displays the shuttle Enterprise, that unflown orbiter would also be up for grabs by another venue.
NASA Administrator Charles Bolden will decide the final site selections. He is scheduled to announce the winner of the nationwide competition on April 12, which is the 30th anniversary of the first shuttle flight (STS-1) by Columbia on April, 12, 1981.
Another location that plays a pivoital role in the U.S. space program is NASA’s Johnson Space Center in Houston, Texas, home to Mission Control. Johnson Space Center is also home base for the shuttle astronauts and houses the facilities where they train for space missions. The Johnson Visitor Center – Space Center Houston – has proposed a 53,000 square foot pavilion with interactive exhibits.
The proposed new 53,000-square-foot space shuttle exhibit located at the Visitor Center at the NASA Johnson Space Center in Houston will be an interactive, educational experience that encourages student interest and commitment to science, technology, engineering and math (STEM) education.

Many of those who work on space projects feel strongly that two of the orbiters should unquestionably be awarded to the Kennedy Space Center (KSC) and the Johnson Space Center JSC) since these are the two locations most intimately involved with the Space Shuttle program. All the crews were trained at JSC and blasted off to space from KSC.
Among the other contenders in the running to house an orbiter are; the Intrepid Sea-Air-Space Museum in New York City; the Adler Planetarium in Chicago; the National Museum of the Air Force in Dayton, Ohio; the U.S. Space & Rocket Center in Huntsville, Alabama; the Museum of Flight in Seattle.

At the Kennedy Visitor Complex, a brand new 64,000 square-foot hall would be constructed to display the orbiter “In Flight”. The exhibit would engage viewers in an up close experience to see how the vehicle actually worked in space and also feature its major accomplishments; such as building the International Space Station (ISS) and upgrading the Hubble Space Telescope.
The orbiter home is projected to cost some $100 million and would be the marquee element of the master plan entailing a transformative overhaul of the entire visitor complex at Kennedy, according to Moore.
The KSCVC concept is outlined in a thick book with extensively detailed story boards and drawings. Clearly, a lot of hard work and thought has gone into designing KSCVC’s proposal to house an orbiter and integrate it with a complete renovation and update of the spaceport tour facilities. The goal is to satisfy the interests of the whole family- not just hard core space geeks.
“We (KSCVC) will display the orbiter tilted, like it is flying in space and at work. Because that’s the way people think about the orbiter – working in space. Not sitting on the ground on three wheels,” Moore explained to me.
“So, our job at KSC is to show the shuttle’s working time as it is flying in space. The payload bay doors will be open and the robotic arm will be extended. Some type of cargo will be inside. We will also show the Hubble and the ISS with models, giant video screens and murals, because we think that’s key to understanding the role of the shuttle.”
Tilted Endeavour 'In Flight'
This tilted view of Space Shuttle Endeavour ‘In Flight’ may give an impression of what visitors might experience in the shuttle orbiter exhibit planned by the Kennedy Space Center Visitor Complex if they are selected as a permanent home for the retired vehicle.

The photo has been rotated 90 degrees to look as though it were horizontal. Credit: Ken Kremer
Moore told me that this will be the largest building ever constructed at KSCVC, even bigger than the popular Shuttle Launch Experience completed a few years back.
“When people come into the exhibit, their first view will be to see the orbiter as though someone would see it by looking out from the ISS, up against a gorgeous backdrop of the Earth, the Sky and the Universe.”
“The point is to make you believe that you are actually seeing the orbiter in space. Visitors will be able to view the orbiter from many different angles,” said Moore.
The shuttle will be shown as it really looks and is flown with the heat shield tiles, with all its scorch marks, pits, scars and imperfections.
“We do not want the orbiter to be polished to a pristine state,” Moore stated firmly.
“We want to expose as many people as possible from around the world to this wonderful vehicle and to what’s happened up there in space.”
“The vehicle is just part of the story. The story is much bigger.
Historic Final Landing of Space Shuttle Discovery
Space Shuttle Discovery concluded her magnificent final journey with a safe landing on March 9, 2011 at the Kennedy Space Center in Florida. Discovery is the first shuttle to be retired and will likely be housed at the Smithsonian National Air and Space Museum in Washington, DC. Credit: Ken Kremer
“The purpose of the display building is that we want to show the whole story of what the shuttle has done and all the major milestones. The people who processed and cared for the orbiters are also part of the story,” Moore amplified.
“We will remember and show the story of those who made the ultimate sacrifice, what we learned from the accidents and then fixed lots of issues to get to a better flight system.”
I asked Moore, when will the exhibit open ? “I would like to open the exhibit by mid to late 2013,” he replied.
The orbiter will be showcased with components from the shuttle’s history. “We have the beanie cap, the white room and a fairly large collection of many other artifacts, parts and items beyond just the orbiter that will be used to tell the story of the shuttle program.”
“The shuttle story covers 30 remarkable years,” said Moore.
Only two flights remain until the shuttles are forcibly retired for lack of many and some say willpower to continue exploring.
The final flight of Endeavour on the STS-134 mission is set for April 19. Atlantis is honored with the shuttle programs very last mission, STS-135, slated for late June 2011.
Discovery just landed on her historic final mission on March 9 – a thrilling and bittersweet experience for all who work and report on the shuttle program. Discovery is being decommissioned and now belongs to history although she has a lot of life left in her.
Stay tuned for the April 12 announcement of the Orbiter homes selected.

The next major program initiative is a new Space Gallery which would house the orbiter in a new climate controlled Iindoor display hanger. The Air Force is most interested in Atlantis due to it being the primary Air Force/Department of Defense shuttle. Atlantis has included more than 30 Air Force astronauts among its crews.

Lockheed Martin is aiming for a first unmanned orbital test flight of Orion as soon as 2013, said John Karas, vice president and general manager for Lockheed Martin’s Human Space Flight programs in an interview with Universe Today . The first operational flight with humans on board is now set for 2016 as stipulated in the NASA Authorization Act of 2010.
Orion manned capsule could launch in 2016 atop proposed NASA heavy lift booster from the Kennedy Space Center This Orion prototype capsule was assembled at NASA’s Michoud Assembly Facility (MAF) in New Orleans, LA and shipped by truck to Denver. At Denver, the capsule will be put through a rigorous testing program to simulate all aspects of a space mission from launch to landing and examine whether the vehicle can withstand the harsh and unforgiving environment of deep space.
Orion was originally designed to be launched by the Ares 1 booster rocket, as part of NASA’s Project Constellation Return to the Moon program, now cancelled by President Obama. The initial Orion test flight will likely be atop a Delta IV Heavy rocket, Karas told me. The first manned flight is planned for the new heavy lift rocket ordered by the US Congress to replace the Project Constellation architecture.
The goal is to produce a new, US-built manned capsule capable of launching American astronauts into space following the looming forced retirement of NASA’s Space Shuttle orbiters later this year. Thus there will be a gap of at least three years until US astronauts again can launch from US soil.
“Our nation’s next bold step in exploration could begin by 2016,” said Karas in a statement. “Orion was designed from inception to fly multiple, deep-space missions. The spacecraft is an incredibly robust, technically advanced vehicle capable of safely transporting humans to asteroids, Lagrange Points and other deep space destinations that will put us on an affordable and sustainable path to Mars.”

Following installation of the heat shield and thermal backshell panels, the spacecraft will undergo rigorous testing to validate Orion’s ability to endure the harsh environments of deep space.

Lockheed Martin is the prime contractor for Orion under a multiyear contract awarded by NASA worth some $3.9 Billion US Dollars.
The SOSC was built at a cost of several million dollars. The 41,000 square foot facility will be used to test and validate vehicles, equipment and software for future human spaceflight programs to ensure safe, affordable and sustainable space exploration.
Mission scenarios include docking to the International Space Station, exploring the Moon, visiting an Asteroid and even journeying to Mars. Lockheed has independently proposed the exploration of several challenging deep space targets by astronauts with Orion crew vehicles which I’ll report on in upcoming features.

The SOSC facility provides the capability for NASA and Lockheed Martin engineers to conduct full-scale motion simulations of many types of manned and robotic space missions. Demonstrations are run using laser and optically guided robotic navigation systems.
Inside the SOSC, engineers can test the performance of a vehicles ranging, rendezvous, docking, proximity operations, imaging, descent and landing systems for Earth orbiting mission as well as those to other bodies in our solar system.
“The Orion spacecraft is a state-of-the-art deep space vehicle that incorporates the technological advances in human life support systems that have accrued over the last 35 years since the Space Shuttle was designed.” says Karas. “In addition, the Orion program has recently been streamlined for additional affordability, setting new standards for reduced NASA oversight. Orion is compatible with all the potential HLLVs that are under consideration by NASA, including the use of a Delta IV heavy for early test flights.”
The Orion flight schedule starting in 2013 is however fully dependent on the level of funding which NASA receives from the Federal Government.
This past year the, Orion work was significantly slowed by large budget cuts and the future outlook is murky. Project Orion is receiving about half the funding originally planned by NASA.
And more deep cuts are in store for NASA’s budget – including both manned and unmanned projects – as both political parties wrangle about priorities as they try to pass a federal budget for this fiscal year. Until then, NASA and the entire US government are currently operating under a series of continuing resolutions passed by Congress – and the future is anything but certain.

Opportunity made landfall at the western edge of Santa Maria on Dec. 15, 2010 (Sol 2450) after a long and arduous journey of some 19 kilometers since departing from Victoria Crater nearly two and one half years ago in September 2008. Santa Maria is the largest crater that the rover will encounter on the epic trek between Victoria and Endeavour.

Credit: NASA/JPL/CornellThe science team decided that Santa Maria would be the best location for an intermediate stop as well as permit a focused science investigation because of the detection of attractive deposits of hydrated minerals. The stadium sized and oval shaped crater is some 80 to 90 meters wide (295 feet) and about nine meters in depth.
Opportunity has since been carefully driven around the lip of the steep walled crater in a counterclockwise direction to reach the very interesting hydrated sulfates on the other side. The rover made several stops along the way to collect long baseline high resolution stereo images creating 3 D digital elevation maps and investigate several rocks in depth.
Opportunity was directed to Santa Maria based on data gathered from Mars orbit by the mineral mapping CRISM spectrometer – onboard the Mars Reconnaissance Orbiter (MRO) – which indicated the presence of exposures of water bearing sulfate deposits at the southeast rim of the crater.

“Santa Maria is a relatively fresh impact crater. It’s geologically very young, hardly eroded at all, and hard to date quantitatively,” said Ray Arvidson from Washington University in St. Louis. Arvidson is the deputy principal investigator for the Spirit and Opportunity rovers.
The rover had to take a pause anyway in its sojourn to Endeavour because of a restrictive period of solar conjunction. Conjunction is the period when the Sun is directly in between the Earth and Mars and results in a temporary period of communications disruptions and blackouts.
During conjunction – which lasted from Jan. 28 to Feb. 12 – the rover remained stationary. No commands were uplinked to Opportunity out of caution that a command transmission could be disrupted and potentially have an adverse effect.
Advantageously, the pause in movement also allows the researchers to do a long-integration assessment of the composition of a selected target which they might not otherwise have conducted.
By mid-January 2011, Opportunity had reached the location – dubbed ‘Yuma’ – at the southeast rim of the crater where water bearing sulfate deposits had been detected. A study of these minerals will help inform researchers about the potential for habitability at this location on the surface of Mars.

The rover turned a few degrees to achieve a better position for deploying Opportunity’s robotic arm, formally known as the instrument deployment device or IDD, to a target within reach of the arms science instruments.
“Opportunity is sitting at the southeast rim of Santa Maria,” Arvidson told me. “We used Opportunity’s Rock Abrasion Tool (RAT) to brush a selected target and the Moessbauer spectrometer was placed on the brushed outcrop. That spot was named ‘Luis De Torres’, said Arvidson.
Ruiz Garcia rock imaged by pancam camera on Sol 2419. Credit: NASA/JPL/Cornell‘Luis De Torres’ was chosen based on the bright, extensive outcrop in the region in which CRISM sees evidence of a hydrated sulfate signature.”
Opportunity successfully analyzed ‘Luis De Torres’ with all the instruments located at the end of the robotic arm; including the Microscopic Imager (MI), the alpha particle X-ray spectrometer (APXS) and then the Moessbauer spectrometer (MB) for a multi-week integration of data collection.
After emerging in fine health from the conjunction, the rover performed a 3-millimeter deep grind on ‘Luis De Torres’ with the RAT in mid-February 2011 to learn more about the rocks interior composition. Opportunity then snapped a series of microscopic images and collected spectra with the APXS spectrometer.
The rover then continued its counterclockwise path along the eastern edge of the crater, driving northwards some 30 meters along the crater rim to a new exposed rock target – informally named ‘Ruiz Garcia’ to collect more APXS spectra and microscopic images. See our mosaic showing “Ruiz Garcia” at the lip of the crater (above).
Opportunity finished up the exploration of the eastern side of Santa Maria in March by snapping a few more high resolution panoramas before resuming the drive to Endeavour crater which lies some 6.5 kilometers (4 miles) away.
Endeavour is Opportunity’s ultimate target in the trek across the Martian dunes because it possesses exposures of a hitherto unexplored type of even more ancient hydrated minerals, known as phyllosilicates, that form in neutral water more conducive to the formation of life.

Virtual Vesta. Taking their best guess, the science team on NASA’s Dawn Asteroid Orbiter have created a series of still images and videos (see below) to simulate what the protoplanet Vesta might look like. The exercise was carried out by mission planners at NASA's Jet Propulsion Laboratory and science team members at the German Aerospace Center and the Planetary Science Institute.

The excitement is building as NASA’s innovative Dawn spacecraft closes in on its first protoplanetary target, the giant asteroid Vesta, with its camera eyes now wide open. The probe is on target to become the first spacecraft from Earth to orbit a body in the main asteroid belt and is set to arrive about four months from now in late July 2011.
Vesta is the second most massive object in the Asteroid Belt between Mars and Jupiter (map below). Since it is also one of the oldest bodies in our Solar System, scientists are eager to study it and search for clues about the formation and early history of the solar system. Dawn will spend about a year orbiting Vesta. Then it will fire its revolutionay ion thrusters and depart for Ceres, the largest asteroid in our solar system.
Dawn is equipped with three science instruments to photograph and investigate the surface mineralogy and elemental composition of the asteroid. The instruments were provided by the US, Germany and Italy. The spacecraft has just awoken from a six month hibernation phase. All three science instruments have been powered up and reactivated.
Dawn will image about 80 percent of Vesta’s surface at muliple angles with the onboard framing cameras to generate topographical maps. During the year in orbit, the probe will adjust its orbit and map the protoplanet at three different and decreasing altitudes between 650 and 200 kilometers, and thus increasing resolution. The cameras were provided and funded by Germany.
To prepare for the imaging campaign, mission planners from the US and Germany conducted a practice exercise to simulate the mission as though they were mapping Vesta. The effort was coordinated among the science and engineering teams at NASA’s Jet Propulsion Laboratory, the Institute of Planetary Research of the German Aerospace Center (DLR) in Berlin and the Planetary Science Institute in Tuscon, Ariz.

“We won’t know what Vesta really looks like until Dawn gets there,” said Carol Raymond in a NASA statement. Raymond is Dawn’s deputy principal investigator, based at JPL, who helped orchestrate the activity. “But we needed a way to make sure our imaging plans would give us the best results possible. The products have proven that Dawn’s mapping techniques will reveal a detailed view of this world that we’ve never seen up close before.”
Two teams worked independently and used different techniques to derive the topographical maps from the available data sets. The final results showed only minor differences in spatial resolution and height accuracy.
Using the best available observations from the Hubble Space Telescope and ground based telescopes and computer modeling techniques, they created maps of still images and a rotating animation (below) showing their best guess as to what Vesta’s surface actually looks like. The maps include dimples, bulges and craters based on the accumulated data to simulate topography and thus give a sense of Virtual Vesta in three dimensions (3 D).
“Working through this exercise, the mission planners and the scientists learned that we could improve the overall accuracy of the topographic reconstruction, using a somewhat different observation geometry,” said Nick Mastrodemo, Dawn’s optical navigation lead at JPL. “Since then, Dawn science planners have worked to tweak the plans to implement the lessons of the exercise.”

The framing camera system consists of two identical cameras developed and built by the Max Planck Institute for Solar System Research, Katlenburg-Lindau, Germany and the German Aerospace Center (DLR) in Berlin.
“The camera system is working flawlessly. The dry run was a complete success,” said Andreas Nathues, lead investigator for the framing camera at the Max Planck Institute in Katlenburg-Lindau, Germany.
Since the probe came out of hibernation, the mechanical and electrical components were checked out in mid March and found to be in excellent health and the software was updated.
Dawn is a mission of many firsts.

The twin Framing Cameras at top (white rectangles) and VIR Spectrometer at right. Credit: Ken Kremer The spacecraft is NASA’s first mission specifically to the Asteroid Belt. It will become the first mission to orbit two solar system bodies.
The revolutionary Dawn mission is powered by exotic ion propulsion which is vastly more efficient than chemical propulsion thrusters. Indeed the ability to orbit two bodies in one mission is only enabled via the use of the ion engines fueled by xenon gas.
Vesta and Ceres are very different worlds that orbit between Mars and Jupiter. Vesta is rocky and may have undergone volcanism whereas Ceres is icy and may even harbor a subsurface ocean conducive to life.
Dawn will be able to comparatively investigate both celestial bodies with the same set of science instruments and try to unlock the mysteries of the beginnings of our solar system and why they are so different.
Dawn is part of NASA’sDiscovery program and was launched in September 2007 by a Delta II rocket from Cape Canaveral Air Force Station, Florida.

Cover of Augustine Commision Report. We're still seeking a human spaceflight program
[/caption]
Over at Space Politics, Jeff Foust points out that a provision for an independent study about human spaceflight was quietly included in last year’s NASA authorization act. The parameters of such a study would be similar to the decadal surveys done by the astronomy and planetary science disciplines. Foust reports that last week such a concept for human spaceflight was debated at a small conference where NASA’s Phil McAlister from the Office of Program Analysis and Evaluation said, “I believe in this Academies-like study that will allow the human spaceflight community to come together, like the science community has done for years and years, effectively. With that kind of document and blueprint… then finally, maybe, we can get the long-term consensus required to actually finish one of these programs. That is my sincere hope.”
Would such a study be helpful in giving U.S. human spaceflight unwavering direction and goals that don’t change with each presidential administration?
The debate is continuing in the comment section on Foust’s article and on Twitter, and so far the lines are divided between this being a good idea or one that would never work for human spaceflight.
Some comments suggest this type of survey would be just another exercise on paper that will accomplish nothing – and would be a repeat of the Stafford Report or the Augustine Commission, where programs and direction is suggested, but since it isn’t “law” politicians would ignore it in favor of projects in their own districts.
Others said there isn’t a strong figure in human spaceflight, such as a Steve Squyres who led the recent planetary decadal survey (although someone suggested Wayne Hale or Bill Gerstenmaier).
On the other side of the debate, still others said that some kind of consensus review is needed in order to direct NASA’s priorities with human space flight, as there has been no clear sustainable direction since the decision to build the ISS. Someone suggested this would be helpful for the international partner, as well, to know what NASA might do next.
What are your views – would a decadal survey for US human spaceflight be a good idea?
'High Texture Hand Embroidery of the Moon,' by Rachel Barry Hobson, which won the NASA/Etsy craft contest in the 2D Original category. Image courtesy of Rachel Barry Hobson
[/caption]
If you aren’t yet familiar with Etsy, it is an arts and crafts goldmine where you can find almost anything your heart desires when it comes to handmade art, jewelry, knick-knacks, photography, clothing, quilts, toys and more. Not surprisingly, space exploration and astronomy is an inspiration for many crafters, and NASA and Etsy held a “Space Craft” contest, where contestants entered an original handmade item or work of art inspired by NASA programs, such as the space shuttle, human spaceflight, aeronautics, science and exploration of the universe, and the winners have now been announced.
I was thrilled to see the winner in one category, the 2D Original category, was this beautiful hand-embroidered representation of the Moon (above) – because not only was it my favorite in the entire contest, but I also know the creator, Rachel Barry Hobson. Her winning piece may fly on one of the final space shuttle flights.
I asked Rachel how she felt about winning, and she said, “I am truly humbled. When I created this piece, I worked from a place of pure passion and love for embroidery and space exploration. I love having the opportunity to use this medium to inspire people to fall in love with space, and to be recognized by peers and such a distinguished panel of judges is a huge honor.”
One of the judges was astronaut Steve Robinson.

Other winners include Colleen and Eric Whiteley from Brooklyn, NY, who received the Grand Prize for Best of Show for their detailed design of the Northstar Table. The table features a North Star design that, when pressed, opens a hidden drawer.
For the category of Two Dimensional Reproduction, “Universal Thoughts” by Nikkita Karsan Bhakta from Mobile, Ala., won the top prize.
Winner, 3D Original. Brother Sun, Sister Moon Ring by Partrick Burt. Image credit: Ets
Patrick Burt from Tempe, Ariz., won the Three Dimensional Original category with a Titanium ring titled “Brother Sun, Sister Moon.” The silver, gold and diamond embedded ring represents stars, the sun, moon, Mercury, Mars, Venus, Jupiter and Saturn.
NASA said their goal for the contest was to help inform Etsy’s 5.8 million members about the agency’s present and future exploration plans. There were over 600 pieces entered in the contest.
Rachel said she was inspired to capture the gorgeous textures and geologic attributes of the Moon in hand embroidery, as “the moon has always served as artistic and scientific inspiration for humankind. It’s easily recognizable, and is a comforting, welcome sight in our sky. Its violently beautiful craters remind us what an active place our solar system is. When I observe the Moon through my telescope, I literally get weak in the knees.”
Like many of us, Rachel said when she was young she dreamed of one day flying in space. “My life ended up taking me down a different path, and for a long time I thought there was no way I’d be able to participate in the space program,” she said. “Connecting with a great community of space enthusiasts online and finding a way to use my art to express my passion for space has helped me realize dreams I’d almost given up on. I’m so thankful for both the space “geek” community and craft community supporting my work and the work of so many incredibly talented Space Tweep artists.”
The grand prize team received a $500 shopping spree on Etsy and an all-expense-paid trip with a guest to attend the next shuttle launch at NASA’s Kennedy Space Center in Florida. Shuttle Endeavour and its crew are targeted to lift off on April 19. The winning two dimensional art piece (and pictures of the others) may be flown aboard the flight, or perhaps STS-135.
The winner of each category received a $250 shopping spree on Etsy and a gift package of NASA and Etsy merchandise.
Congrats on to the winners and hats off to NASA and Etsy for recognizing we all have our own unique way of expressing our spaciness!

Curiosity, also known as the Mars Science Laboratory or MSL, is the size of a mini-Cooper. It was placed inside a 7.6 meter (25 foot) diameter high vacuum chamber at NASA’s Jet Propulsion Laboratory. Engineers are now conducting an extensive regimen of tests that will check out the performance and operational capabilities of the rover under Mars-like conditions.
Curiosity enters the 7.6-meter-diameter space-simulation chamber on March 8, 2011 at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The rover is fully assembled with all primary flight hardware and instruments. The test chamber's door is still open in this photo.

The internal chamber temperature was decreased to minus 130 degrees Celsius (minus 202 degrees Fahrenheit) using liquid nitrogen flowing through the chamber walls to approximate the Antarctic like bone chilling cold. Martian lighting conditions are being simulated by a series of powerful lamps.
Upon successful completion of the testing, all components of the MSL spacecraft system will be shipped to the Kennedy Space Center for final integration. This includes the cruise stage, descent stage and back shell.
MSL will land using a new and innovative sky crane system instead of airbags. Using the helicopter-like sky crane permits the delivery of a heavier rover to Mars and with more weight devoted to the science payload. Indeed the weight of Curiosity’s science payload is ten times that of any prior Mars rover mission.

MSL also features a precision landing system to more accurately guide the rover to the desired target than past missions, to within an ellipse about 20 kilometers long. After extensive evaluation, four landing sites where water once flowed have been selected for further evaluation. The final decision will come sometime in 2011.
Curiosity is about twice the size and four times the weight compared to NASA’s Spirit and Opportunity Mars Explorations Rovers which landed on Mars back in 2004. Opportunity continues to stream back science data from Mars after seven years. The fate of Spirit is unknown at this time as the plucky rover has been out of contact since entering hibernation in March 2010.
The science goal of Curiosity is to search the landing site for clues about whether environmental conditions favorable for microbial life existed in the past or even today on Mars and whether evidence for life may have been preserved in the geological record.
The rover is being targeted to an area where it is believed that liquid water once flowed and may be habitable. In particular the science teams hope to sample and investigate phyllosilicate clays, which are minerals that form in neutral watery conditions more favorable to the formation of life compared to the more acidic environments investigated thus far by Spirit and Opportunity.

Space Shuttle Endeavour now sits majestically at launch pad 39 A at the Kennedy Space Center, awaiting her historic final spaceflight on the STS-134 mission. Following her nighttime rollout to the pad, I was part of a lucky band of photographers and journalists permitted to travel along and participate in the ultimate photo op on a picture perfect day.
NASA allowed us to get breathtakingly close and document Endeavour from multiple absolutely awesome vantage points all around the launch pad from top to bottom. We were given access to shoot from the upper reaches of the launch gantry with stunning panoramic vistas of the Florida coastline to the bottom of the launch platform and standing directly beneath the External Tank and adjacent to the Twin Solid Rocket Boosters.
Here is part 1 of my photo album which focuses on the upper levels and includes our visit to the White Room – where the astronauts enter the crew hatch to board the shuttle orbiter to take their seats for the adventure of a lifetime.

With the shuttle era rapidly drawing to a close, NASA has opened up media access in ways not previously allowed so that we can share these rarely seen views of the shuttle with the public.

STS-134 will be the 25th and final flight for Space Shuttle Endeavour. Liftoff is set slated for April 19 with an all veteran crew of six, led by Shuttle Commander Mark Kelly.
Endeavour will haul the Alpha Magnetic Spectrometer (AMS) to orbit and attach this premiere science experiment to the truss structure of the International Space Station. AMS will search for dark matter and antimatter and seak to determine the origin of the universe.

Star Trek’s Data must be smiling.
One of his kind has finally made it to the High Frontier. The voyages of Robo Trek have begun !
Robonaut 2, or R2, was finally unleashed from his foam lined packing crate by ISS crewmembers Cady Coleman and Paolo Nespoli on March 15 and attached to a pedestal located inside its new home in the Destiny research module. R2 joins the crew of six human residents as an official member of the ISS crew. See the video above and photos below.

The fancy shipping crate goes by the acronym SLEEPR, which stands for Structural Launch Enclosure to Effectively Protect Robonaut. R2 had been packed inside since last summer.
”Robonaut is now onboard as the newest member of our crew. We are happy to have him onboard. It’s a real good opportunity to help understand the interface of humans and robotics here in space.” said Coleman. “We want to see what Robonaut can do. Congratulations to the team of engineers [at NASA Johnson Space center] who got him ready to fly.”

Discovery blasted off for her historic final mission on Feb. 24 and made history to the end by carrying the first joint Human-Robot crew to space.
“It feels great to be out of my SLEEPR, even if I can’t stretch out just yet. I can’t wait until I get to start doing some work!” tweeted R2.
The 300-pound R2 was jointly developed in a partnership between NASA and GM at a cost of about $2.5 million. It consists of a head and a torso with two arms and two hands. It was designed with exceptionally dexterous hands and can use the same tools as humans.

R2 will function as an astronaut’s assistant that can work shoulder to shoulder alongside humans and conduct real work, ranging from science experiments to maintenance chores. After further upgrades to accomplish tasks of growing complexity, R2 may one day venture outside the ISS to help spacewalking astronauts.
“It’s a dream come true to fly the robot to the ISS,” said Ron Diftler in an interview at the Kennedy Space Center. Diftler is the R2 project manager at NASA’s Johnson Space Center.
President Obama called the joint Discovery-ISS crew during the STS-133 mission and said he was eager to see R2 inside the ISS and urged the crew to unpack R2 as soon as possible.
“I understand you guys have a new crew member, this R2 robot,” Obama said. “I don’t know whether you guys are putting R2 to work, but he’s getting a lot of attention. That helps inspire some young people when it comes to science and technology.”
Commander Lindsey replied that R2 was still packed in the shipping crate – SLEEPR – and then joked that, “every once in a while we hear some scratching sounds from inside, maybe, you know, ‘let me out, let me out,’ we’re not sure.”
Robonaut 2 is free at last to meet his destiny in space and Voyage to the Stars.
“I don’t have a window in front of me, but maybe the crew will let me look out of the Cupola sometime,” R2 tweeted from the ISS.
