The mosaic shows Curiosity’s eventual mountain destination – Mount Sharp – to its visible peak at the right, as well as the eroded rim of Gale Crater and a rover partial self portrait. Curiosity cannot see the actual summit from the floor of Gale Crater at Bradbury landing.

In about a year, the 1 ton behemoth will begin climbing up the side of Mount Sharp – a layered mountain some 3.4 miles (5.5 kilometers) high that contains deposits of hydrated minerals.

Curiosity will investigate and sample soils and rocks with her powerful suite of 10 state of the art science instruments.

See below JPL’s individual right and left eye pano’s from which the 3-D mosaic was created.

The rover has now departed Bradbury landing and begun her long Martian Trek on an easterly path to Glenelg – her first stop designated for a lengthy science investigation.

Glenelg lies at the intersection of three distinct types of geologic terrain.

So far Curiosity has driven 358 feet (109 meters) and is in excellent health.

Changing Hues Signal Transition of Seasons at Saturn

[SPOILER ALERT: Viewing these images will force you to change your computer wallpaper]

Here on Earth, it’s almost time for the burst of fall color that signals the change of seasons in the Northern Hemisphere. Saturn’s color too is transforming subtly as the gas giant slips into a Saturnian spring and autumn as seen in this series of true-color images from NASA’s Cassini spacecraft.

Titan, a moon larger than the planet Mercury, hangs before the rings and changing colors of Saturn in the first of four spectacular images release by NASA and the Cassini Imaging Central Laboratory for Operations (CICLOPS).

“For no other reason than that they are gorgeous, the Cassini imaging team is releasing today a set of fabulous images of Saturn and Titan…in living color…for your day-dreaming enjoyment,” said Carolyn Porco, Cassini imaging team lead based at the Space Science Institute in Boulder, Colordo, in an email blast.

When Cassini arrived at Saturn eight years ago, the planet’s northern hemisphere, locked in winter, showed azure blue. Now as winter passes to the southern hemisphere, the colors are reversing as the blue fades from the north and rises in the south.

“Note that our presence at Saturn for the last eight years has made possible the sighting of subtle changes with time, and one such change is obvious here,” Porco said. “As the seasons have advanced, and spring has come to the north and autumn to the south throughout the Saturn system, the azure blue in the northern winter Saturnian hemisphere that greeted Cassini upon its arrival in 2004 is now fading; and it is now the southern hemisphere, in its approach to winter, that is taking on a bluish hue.”

Scientists believe that the increasing blue color in the south likely is due to the increasing intensity of ultraviolet light from the Sun which produces the haze. Methane in the atmosphere also absorbs light toward the red end of the spectrum while reflecting blue light. This view looks from just above the ring plane with the Sun shining from above casting broad shadows on the colorful clouds of Saturn. The image was taken on May 6, 2012 from about 778,000 kilometers (483,000 miles) from Titan.

Some of the views, including this image of a vortex at Titan’s south pole are only possible because of a newly tilted, or inclined, orbit that takes Cassini high over the poles of Saturn and its moons. Scientists first noticed the detached mass of clouds over the south pole in March. The swirling mass of the vortex stands out clearly against the golden cloud deck surrounding Titan.

A glowing hint of the polar vortex shows in this image looking toward the night-time, Saturn-facing side of Titan. Sunlight scattering through Titan’s atmosphere forms the ring of color in this image taken about 216,000 kilometers (134,000 miles) from Titan.

The rings obscure Titan in the final image of the quartet. The image is taken from just above the northern, sunlit side of the ring plane. Saturn’s shadow cast along the rings create the dark swath in the center of the image but if you look close, you can see a tiny sliver of Titan through the Cassini Division, the largest gap in Saturn’s wide rings.

“Cassini has been in orbit now for the last eight years, and despite the fact that we can’t know exactly what the next five years will show us, we can be certain that whatever it is will be wondrous,” said Porco.

Mars Trek begins for Curiosity

Mars Trek has begun for NASA’s Curiosity rover. The mega rover has departed from her touchdown vicinity at “Bradbury Landing” and set off on a multi-week eastwards traverse to her first science target which the team has dubbed “Glenelg”

Glenelg lies about a quarter mile (400 meters) away and the car-sized rover drove about 52 feet (16 meters) on Tuesday, Aug 28 or Sol 22 of the mission.

The science team selected Glenelg as the first target for detailed investigation because it sits at the intersection of three types of geologic terrain, affording the researchers the chance to get a much more comprehensive look at the diversity of geology inside the Gale Crater landing site.

The Sol 22 drive was the third overall for Curiosity and the farthest so far. At this new location, some 33 feet ( 10 m) from Bradbury Landing , the Mastcam color camera is collecting high resolution images to create a 3 D map of features off in the distance that will aid the rover drivers in planning a safe traverse route.

“This drive really begins our journey toward the first major driving destination, Glenelg, and it’s nice to see some Martian soil on our wheels,” said mission manager Arthur Amador of NASA’s Jet Propulsion Laboratory in Pasadena, Calif. “The drive went beautifully, just as our rover planners designed it.”

In about a week, the science team plans to deploy the 7 ft (2.1 meter) long robotic arm and test the science instruments in the turret positioned at the terminus of the arm.

“We are on our way, though Glenelg is still many weeks away,” said Curiosity Project Scientist John Grotzinger of the California Institute of Technology in Pasadena. “We plan to stop for just a day at the location we just reached, but in the next week or so we will make a longer stop.”

Perhaps in about a year or so, Curiosity will reach the base of Mount Sharp, her ultimate destination, and begin climbing up the side of the 3.6 mile (5.5 km) high mound in search of hydrated minerals that will shed light on the duration of Mars watery past.

The goal is to determine if Mars ever had habitats capable of supporting microbial life in the past or present during the 2 year long primary mission phase. Curiosity is equipped with a sophisticated array of 10 state of the art science instruments far beyond any prior rover.

In memory of Neil Armstrong, First Man to set foot on the Moon, here’s a summary of Apollo 11 highlights and a collection of some tributes and photos to celebrate his life and the indelible inspiration he gave to current generations and all those yet to come to take up the noble torch for science and exploration. He became an everlasting icon for the ages when he took, “one giant leap for mankind”, and accomplished one of the greatest feats in human history.

Armstrong passed away at age 82 on Saturday, August 25, 2012 due to complications from heart bypass surgery.

Neil Armstrong was the commander of the three man crew of Apollo 11, which included Buzz Aldrin and Michael Collins.

The trio blasted off on their bold, quarter of a million mile moon mission from Cape Canaveral, Florida on July 16, 1969 to fulfill the lunar landing quest set by President John F. Kennedy early in the decade.


Armstrong and Aldrin safely touched down at the Sea of Tranquility on the lunar surface on July 20, 1969 as hundreds of millions across the globe watched in awe and united in purpose.

“Houston, Tranquility Base here. The Eagle has landed !,” Armstrong called out and emotional applause erupted at Mission Control – “You got a bunch of guys about to turn blue.”

Armstrong carried all of humanity with him when he stepped off the footpad of NASA’s Apollo 11 Lunar Module and became the first representative of the human species to walk on the surface of another celestial body.

His first immortal words,

“That’s one small step for [a] man, one giant leap for mankind.”

During their 2 ½ hours moonwalk Armstrong and Aldrin unveiled a plaque on the side of the lunar module. Armstrong read the words;

“Here men from the planet Earth first set foot upon the moon. July 1969 A.D. We came in peace for all mankind.”

The duo collected about 50 pounds (22 kg) of priceless moon rocks and set out the first science experiments placed by people on another world.

Altogether Armstrong and Aldrin spent about 21 hours on the moon’s surface. Then they said goodbye to the greatest adventure and fired up the LM ascent engine to rejoin Michael Collins circling above in the Apollo 11 Command Module.

Tributes to Armstrong have been pouring in – He is often described as a reluctant hero who gave credit to others.

“Armstrong, the lunar Adam,” wrote Virginia Adams

In a statement, NASA Administrator Charles Bolden said in part,

“As long as there are history books, Neil Armstrong will be included in them, remembered for taking humankind’s first small step on a world beyond our own.

“Besides being one of America’s greatest explorers, Neil carried himself with a grace and humility that was an example to us all. When President Kennedy challenged the nation to send a human to the moon, Neil Armstrong accepted without reservation.

“As we enter this next era of space exploration, we do so standing on the shoulders of Neil Armstrong. We mourn the passing of a friend, fellow astronaut and true American hero.”

Armstrong’s family released a statement that said in part;

“We are heartbroken to share the news that Neil Armstrong has passed away following complications resulting from cardiovascular procedures.

“Neil was our loving husband, father, grandfather, brother and friend.

“Neil Armstrong was also a reluctant American hero who always believed he was just doing his job. He served his Nation proudly, as a navy fighter pilot, test pilot, and astronaut. He also found success back home in his native Ohio in business and academia, and became a community leader in Cincinnati.

“For those who may ask what they can do to honor Neil, we have a simple request. Honor his example of service, accomplishment and modesty, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink.”

“He was the best, and I will miss him terribly,” said Michael Collins, Apollo 11 command module pilot.

Buzz Aldrin, Apollo 11 lunar module pilot, released a statement that said in part,

“I am very saddened to learn of the passing of Neil Armstrong today. Neil and I trained together as technical partners but were also good friends who will always be connected through our participation in the Apollo 11 mission. Whenever I look at the moon it reminds me of the moment over four decades ago when I realized that even though we were farther away from earth than two humans had ever been, we were not alone. Virtually the entire world took that memorable journey with us.”

Neil Armstrong, First Man on the Moon, Dies at 82

Former NASA astronaut Neil A. Armstrong was born in Wapakoneta, Ohio, on August 5, 1930

Today we mourn the loss of a true hero and icon of a generation, if not an entire century: Neil Alden Armstrong, former NASA astronaut and first person to set foot on the Moon, has passed away due to complications from cardiovascular surgery. Armstrong had recently turned 82 years old on August 5.

His family has issued the following statement:

We are heartbroken to share the news that Neil Armstrong has passed away following complications resulting from cardiovascular procedures.

Neil was our loving husband, father, grandfather, brother and friend.

Neil Armstrong was also a reluctant American hero who always believed he was just doing his job. He served his Nation proudly, as a navy fighter pilot, test pilot, and astronaut. He also found success back home in his native Ohio in business and academia, and became a community leader in Cincinnati.

He remained an advocate of aviation and exploration throughout his life and never lost his boyhood wonder of these pursuits.

As much as Neil cherished his privacy, he always appreciated the expressions of good will from people around the world and from all walks of life.

While we mourn the loss of a very good man, we also celebrate his remarkable life and hope that it serves as an example to young people around the world to work hard to make their dreams come true, to be willing to explore and push the limits, and to selflessly serve a cause greater than themselves.

For those who may ask what they can do to honor Neil, we have a simple request. Honor his example of service, accomplishment and modesty, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink.

His death was reported at 2:45 p.m. ET.

Armstrong commanded the Apollo 11 spacecraft that landed on the moon on July 20, 1969, and he radioed back to Earth the historic news: “That’s one small step for a man, one giant leap for mankind.”

In a statement issued by the White House, U.S. President Barack Obama said “Today, Neil’s spirit of discovery lives on in all the men and women who have devoted their lives to exploring the unknown – including those who are ensuring that we reach higher and go further in space. That legacy will endure — sparked by a man who taught us the enormous power of one small step.”

Neil Armstrong, along with fellow astronauts Buzz Aldrin, Michael Collins and John Glenn, were honored with the Congressional Gold Medal on November 16, 2011.

Godspeed, Mr. Armstrong. You were — and will always be — a true inspiration to so many. You’ll be missed.

“In my own view, the important achievement of Apollo was a demonstration that humanity is not forever chained to this planet, and our visions go rather further than that, and our opportunities are unlimited.”

— Neil A. Armstrong

NASA Looking at Dozens of Advanced Technology Concepts

All the media focus surrounding the recent landing of NASA’S rover Curiosity has brought increased attention to space technology. Just in time to bask in the limelight, NASA has delivered a tech enthusiast’s dream in terms of astounding new concepts that have recently been funded. They range in scope from nanosatellite technology to the exploration under the ice of Europa.

NASA’s Innovative and Advanced Concepts program announced on August 1st that it has funded 28 studies for the upcoming year. Eighteen of the studies are considered “Phase 1” projects, while ten are considered “Phase 2.”

Phase 1 projects are the new, innovative ideas that NASA received during its call for proposals. Some other conepts include an air purification system with no moving parts, and a system that could use in situ lunar regolith to autonomously build concrete structures on the Moon, as pictured above. Each of the winning proposals, from a pool of hundreds, will receive $100,000 to pursue the idea further. Each team will report back to NIAC at the end of the year with a report on their progress toward the goals of the project that were laid out in the proposal.

Phase 2 projects are pulled from the successful proposals from last year that reapplied for another grant. These projects have already made it through their Phase 1 development and will receive $500,000 for continuing research into the concept. These projects include such technologies as fusion-driven rockets and printable space-craft, and could move on to commercial or mission development if they successfully complete their Phase 2 goals. Other parts of NASA’s Office of the Chief Technologist will help support those goals, as the NIAC only supports project up through the completion of Phase 2.

The NIAC ties nicely into NASA’s new focus on the commercial side of space flight. Many of the concepts funded by the program could serve as the basis for viable commercial businesses, such as asteroid mining and robotic construction. But most importantly, NASA is still funding the risky, game-changing projects that could drastically transform the way people live their every-day lives. Tech enthusiasts everywhere should be happy with that concept.

You can see here for a list of the proposals. We’ll try to feature some of these in future articles.

Multiple Dinosaur Tracks Confirmed at NASA Center

At NASA’s Goddard Space Flight Center in Greenbelt, MD, where some of the world’s most advanced research in space technology is being performed on a daily basis, paleontologists have discovered ancient evidence of dinosaurs on the Center’s wooded campus — at least two, possibly a mother and child, crossed that way between 112 and 110 million years ago and left their muddy footprints as proof.

The tracks of two nodosaurs — short, stocky and heavily-armored herbivorous dinosaurs — have been confirmed by dinosaur tracker Ray Stanford and USGS emeritus paleontologist Dr. Robert Weems. The second track is a smaller version of the first.

The first, larger footprint was announced by Stanford on August 17. When Dr. Weems was called in to verify, the smaller print was discovered within the first, evidence that they were made around the same time and leading researchers to suggest it may have been a mother-and-child pair.

“It looks to be a manus (front foot) print of a much smaller dinosaur than the first one, but it looks to be the same type,” Weems said of the second track. “If the one that came through was a female, it may have had one or more young ones following along. If you’ve seen a dog or cat walking with its young, they kind of sniff around and may not go in the same direction, but they end up in the same place.”

It’s thought that the nodosaurs were moving quickly since the tracks don’t show strong imprints of the animals’ heels. Still, the ruddy Cretaceous-era mud preserved their brief passage well — even as millions of years went by.

“This was a large, armored dinosaur,” Stanford said. “Think of it as a four-footed tank. It was quite heavy, there’s a quite a ridge or push-up here. Subsequently the sand was bound together by iron-oxide or hematite, so it gave us a nice preservation, almost like concrete.”

The next steps will be to have the site analyzed to determine whether further excavation is called for, and possibly to extract and preserve the existing footprints.

“Space scientists may walk along here, and they’re walking exactly where this big, bungling heavy armored dinosaur walked, maybe 110 to 112 million years ago.”

XCOR to Move Operations Near Kennedy Space Center

Kennedy Space Center is getting a new neighbor: XCOR Aerospace announced they intend to establish an operational base in Florida, and also hope to build a manufacturing and assembly center for the XCOR Lynx Mark II suborbital reusable launch vehicles.

“Looking over the KSC Visitor Complex grounds and seeing the history of U.S. human spaceflight and realizing that soon XCOR will be a part of the fabric of the Space Coast is very exciting to me personally and our company” said Jeff Greason, XCOR CEO. “When we started the company back in 1999, we could only have dreamt about the possibility of flying the person on the street or the citizen scientist to space from such an important place.”

KSC and NASA officials — as well as local officials dealing with the job losses from the end of the shuttle program — were thrilled with the news. XCOR’s new operations in Florida could bring new work for highly skilled former space shuttle employees.

“The next era in space exploration is under way, and the Space Coast of Florida is ground zero in the Obama administration’s effort to launch Americans from U.S. soil and create good jobs that support an economy built to last,” said NASA Chief of Staff David Radzanowski. “The region continues to be a key strategic location for companies, like XCOR, who want to build on our nation’s great legacy of innovation and entrepreneurship.”

“We look forward to discussing with XCOR Aerospace and other space companies how Kennedy’s unique capabilities may be made available for use,” said Kennedy’s Center Director Bob Cabana. “This is further evidence that the Space Coast is preparing for the next era of space exploration.”

XCOR made the announcement in Florida, with the Kennedy Space Center Visitor Complex as a backdrop.

The company hopes to fly the Lynx suborbital vehicle from Kennedy Space Center’s Shuttle Landing Facility, the Cecil Field Spaceport, or other suitable Florida locations by 2014. And if all goes well, they will also start building facilities to produce parts for the Lynx Mark II models and eventually production of Lynx vehicles and other XCOR products, “should market demand materialize and the emerging commercial space industry maintain its current momentum,” XCOR said in a press release.

They estimate direct job creation through late 2018 at just over 150.

“As chair of Space Florida, this is the type of investment the Space Florida Board has been working on to attract high-tech, high-wage jobs to Florida,” said Florida Lt. Governor Jennifer Carroll. “We are very pleased to welcome XCOR to Florida as a prime example of how utilizing Florida’s existing infrastructure and leveraging our talented workforce capabilities can attract new and growing business to our state.”

NASA said they are working with XCOR and other commercial space companies so that KSC could be host to many kinds of spacecraft and rockets in the future.

“Negotiations are taking place with other commercial users for Orbiter Processing Facility Bays 1 and 2, as well as with potential commercial users of the Launch Complex 39 launch pads,” NASA said in a statement. “These and other partnerships will cement Kennedy as a true multiuser spaceport as envisioned by our nation’s leadership.”

Mars Lander Wins Out for 2016 Mission Over Titan Boat and Comet Hopper

Credit: JPL/NASA

A new mission to Mars will launch in 2016, NASA announced on Monday, a lander named InSight that will probe Mars’ interior to determine whether it has a solid or liquid core, if it actually does have fault lines and plate tectonics, and figure out the Red Planet’s basic internal structure. All of this will not only help scientists understand Mars, but also to gain insight on how terrestrial planets form and evolve.

“We’re very confident that this will produce exciting science,” said John Grunsfeld, NASA’s associate administrator for the agency’s Science Mission Directorate.

InSight won out for this round of NASA’s lowest cost missions, the Discovery missions, over two other very enticing proposals: the Titan Mare Explorer (TiME) would have sent a floating high-tech buoy to land in a methane sea on Saturn’s moon Titan to study its composition and its interaction with the atmosphere; and Chopper was a proposed Comet Hopper mission that would put a lander on comet 46P/Wirtanen where it would study the comet’s composition, and with thrusters it could essentially “hop” to different locations on the comet.

While all three missions in the competition were compelling, NASA only has enough money, unfortunately, for one Discovery mission in 2016. And, Grunsfeld said, InSight was the best choice of a project that could stay at or even under the Discovery program’s $425 million cost cap, excluding launch costs, and keep its tight schedule to launch in 2016.

“Our Discovery Program enables scientists to use innovative approaches to answering fundamental questions about our Solar System in the lowest cost mission category,” said Grunsfeld. “InSight will get to the ‘core’ of the nature of the interior and structure of Mars, well below the observations we’ve been able to make from orbit or the surface.”

Asked during a press briefing if NASA is becoming, too Mars-centric, Grunsfeld replied, “We still have a broad portfolio of missions, with Juno recently launching, OSIRIS-Rex launching in 2016, the Dawn mission going on and New Horizons heading to Pluto, so I think we’ve shown very broad diversity in past selections.”

Grunsfeld was also asked if the Curiosity rover’s recent successful landing had any influence on the choice, but Grunsfeld said the decision was actually made before the Mars Science Laboratory rover touched down.

“We’re really clueless on the interior of Mars,” said NASA’s Planetary Science Chief, Jim Green. “And this is really our first attempt to understand what terrestrial bodies go through in their early evolution.”

Insight’s body is based on the Phoenix lander, which landed in Mars’ polar region in 2008, and will use solar panels for power instead of a radioisotope power system, which saves on costs. But the instrumentation for InSight is completely different than Phoenix, and it involves an international mix.

InSight will carry four instruments: JPL will supply a geodetic instrument to determine the planet’s rotation axis and a robotic arm and two cameras used to deploy and monitor instruments on the Martian surface. The French space agency CNES is leading an international consortium that is building an instrument to measure seismic waves traveling through the planet’s interior. The German Aerospace Center (DLR) is building a subsurface heat probe to measure the flow of heat from the interior.

And don’t expect any great color photos of Mars’ surface from InSight. It will only have a black and white context camera, and Green said they don’t expect any changes in that regard, as the mission will need to stay on budget and on time.

InSight will land in a flat, equatorial, flat region in September 2016 to begin a two-year scientific mission. “The Phoenix lander went to polar regions and we knew it was going to be a short lifetime,” said Grunsfeld. “Because InSight goes to an equatorial region where the environment is relatively more benign, it has the potential to last longer, so that is exciting.”

Green touched on other potential areas of study for InSight, such as determining if there are “Marsquakes,” and whether the landslides seen by the Mars Reconnaissance Orbiter’s HiRISE camera are due to activity on the planet like quakes or from melting.

“Methane is being potentially being produced from Mars’ interior,” Green said, “and that touches upon the potential life question. But that is a potentially active process a-bioticaly, in interactions between water, minerals and magma. And this mission could determine if Mars has a hot interior magma, and why it doesn’t generate a magnetic field. What we are seeing are some of the different perspectives of Mars being an active planet or not, and these instruments will clearly be able to do this.”
