Space Shuttle Endeavour was joined to the 747 Jumbo carrier jet that will carry her majestically on Sept 17 on her final flight to the California Science Center – her permanent new home at the in Los Angeles. Enjoy my photos from onsite at the Kennedy Space Center in Florida.

On Friday (Sept. 14), Endeavour was towed a few miles in the predawn darkness from the Vehicle Assembly Building (VAB ) to the Shuttle Landing Facility (SLF) and the specially modified 747 known as the Shuttle Carrier Aircraft, or SCA.

In a day long process, Endeavour departed the VAB at 5:04 a.m. and was hauled into the gantry-like Mate-Demate device, hoisted and then lowered onto the awaiting 747 Jumbo Jet. The pair were joined at about 2:41 p.m.

Final work to hard mate NASA’s youngest orbiter to the SCA Jumbo Jet known as NASA 905 is due to be completed by Sunday.

The 747 crew will fly perform multiple, crowd pleasing low flyovers of the Florida space coast region, the KSC Visitor complex and the beaches – giving every spectator a thrilling front row seat to this exciting but bittersweet moment in space history as the shuttle takes flight for the very final time.

Everyone involved felt a strong mix of emotions from pride in the tremendous accomplishments of NASA’s Space Shuttle Program to the sad and bittersweet feeling that comes with the retirement of all 3 orbiters barely one third of the way into their design lifetime. All three shuttles could easily have flown tens of millions more miles but for lack of money and political support from Washington D.C.

Altogether Endeavour flew 25 missions and traveled 122,883,151 miles during 299 days in space.

Is Triton Hiding an Underground Ocean?

Voyager 2 mosaic of Neptune’s largest moon, Triton (NASA)

At 1,680 miles (2,700 km) across, the frigid and wrinkled Triton is Neptune’s largest moon and the seventh largest in the Solar System. It orbits the planet backwards – that is, in the opposite direction that Neptune rotates – and is the only large moon to do so, leading astronomers to believe that Triton is actually a captured Kuiper Belt Object that fell into orbit around Neptune at some point in our solar system’s nearly 4.7-billion-year history.

Briefly visited by Voyager 2 in late August 1989, Triton was found to have a curiously mottled and rather reflective surface nearly half-covered with a bumpy “cantaloupe terrain” and a crust made up of mostly water ice, wrapped around a dense core of metallic rock. But researchers from the University of Maryland are suggesting that between the ice and rock may lie a hidden ocean of water, kept liquid despite estimated temperatures of  -97°C (-143°F), making Triton yet another moon that could have a subsurface sea.

How could such a chilly world maintain an ocean of liquid water for any length of time? For one thing, the presence of ammonia inside Triton would help to significantly lower the freezing point of water, making for a very cold — not to mention nasty-tasting — subsurface ocean that refrains from freezing solid.

In addition to this, Triton may have a source of internal heat — if not several. When Triton was first captured by Neptune’s gravity its orbit would have initially been highly elliptical, subjecting the new moon to intense tidal flexing that would have generated quite a bit of heat due to friction (not unlike what happens on Jupiter’s volcanic moon Io.) Although over time Triton’s orbit has become very nearly circular around Neptune due to the energy loss caused by such tidal forces, the heat could have been enough to melt a considerable amount of water ice trapped beneath Triton’s crust.

Related: Titan’s Tides Suggest a Subsurface Sea

Another possible source of heat is the decay of radioactive isotopes, an ongoing process which can heat a planet internally for billions of years. Although not alone enough to defrost an entire ocean, combine this radiogenic heating with tidal heating and Triton could very well have enough warmth to harbor a thin, ammonia-rich ocean beneath an insulating “blanket” of frozen crust for a very long time — although eventually it too will cool and freeze solid like the rest of the moon. Whether this has already happened or still has yet to happen remains to be seen, as several unknowns are still part of the equation.

“I think it is extremely likely that a subsurface ammonia-rich ocean exists in Triton,” said Saswata Hier-Majumder at the University of Maryland’s Department of Geology, whose team’s paper was recently published in the August edition of the journal Icarus. “[Yet] there are a number of uncertainties in our knowledge of Triton’s interior and past which makes it difficult to predict with absolute certainty.”

Still, any promise of liquid water existing elsewhere in large amounts should make us take notice, as it’s within such environments that scientists believe lie our best chances of locating any extraterrestrial life. Even in the farthest reaches of the Solar System, from the planets to their moons, into the Kuiper Belt and even beyond, if there’s heat, liquid water and the right elements — all of which seem to be popping up in the most surprising of places — the stage can be set for life to take hold.

See Armstrong’s Hands and Eyes on the Moon

You see those gloves? Those gloves grasped the lunar ladder as Neil Armstrong hopped down to the moon’s surface on July 20, 1969. Tinged with blue silicon rubber fingertips to help Armstrong feel his way, those gloves carried experiments, and tools, and touched Moon dust. They were the first gloves used while walking on the Moon.

They’ve been in storage for more than a decade. But right now — for at least the next two weeks — they are sitting in a special display case at the Smithsonian’s airport annex in Washington. The National Air and Space Museum Steven F. Udvar-Hazy Center is showing them to the public in honour of Armstrong, who died at the age of 82 on Aug. 25.

Oh yeah, and you can also check out the helmet that Neil Armstrong used as he described the lunar surface to millions of awe-struck listeners on live television. (The gold-plated visor he used on the surface is not being lowered again due to concerns about damaging it, but it’s inside the helmet.) No big deal.

Yes, the surface is fine and powdery. I can kick it up loosely with my toe. It does adhere in fine layers, like powdered charcoal, to the sole and sides of my boots. I only go in a small fraction of an inch, maybe an eighth of an inch, but I can see the footprints of my boots and the treads in the fine, sandy particles.

This is probably your last chance to catch these artifacts before at least 2017. Armstrong’s spacesuit has been in storage since 2001 in a special temperature and humidity-controlled facility, to protect it from damage. The museum has tentative plans to display it again when it renovates the Apollo gallery in the main museum building on the Washington Mall. That said, his crewmate Buzz Aldrin’s spacesuit is on display there right now.

Now you can enjoy the thrills of Curiosity’s touchdown site at Bradbury Landing as if you there – chronicled in stunning 3 D !! Check out this glorious 360-degree stereo panorama just released by JPL.

The pano was assembled by JPL from individual right and left eye images snapped by the rover’s mast mounted navigation cameras on sols 2 and 12 of the mission – Aug. 8 and 18, 2012.

So whip out your handy-dandy, red-blue (cyan) anaglyph glasses and start exploring the magnificent home of NASA’s newest Mars rover inside Gale Crater.

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.

In tribute to Neil Armstrong, first human to grace another world here’s a new gallery of unpublished photos to enjoy as shared by my good friend – space photographer John Salsbury.

Armstrong was the first person to walk on the Moon as the commander of NASA’s Apollo 11 flight in 1969. Neil passed away on August 25, 2012 at age 82.

Salsbury writes, “I was fortunate enough to be at the KSC Saturn Exhibit for this photo op of the 30th Anniversary of Apollo 11 on July 16, 1999. These photos were the best I could get using my Minolta XGM 135 mm and Kodak 1000 with no flash.”

On Friday August 31, a private memorial service was held in Cincinnati, Ohio (photos below) to pay tribute to Neil Armstrong. Numerous dignitaries attended the service including his two surviving crewmates Buzz Aldrin and Michael Collins

NASA released this statement from NASA Administrator Charles Bolden

“Today, we pay tribute to a pioneering American; an explorer, a patriot and an individual who, with ‘one small step,’ achieved an impossible dream. Family, friends and colleagues of Neil’s gathered to reflect on his extraordinary life and career, and offer thanks for the many blessings he shared with us along the way.

His remarkable achievements will be forever remembered, and his grace and humility will always be admired. As we take the next giant leap forward in human exploration of our vast universe, we stand on the shoulders of this brave, reluctant hero. Neil Armstrong’s first step on the moon paved the way for others to be the ‘first’ to step foot on another planet. We have an obligation to carry on this uniquely American legacy.

A grateful nation offers praise and salutes a humble servant who answered the call and dared to dream.”

Researchers Send Mars Some Radar Love

A radar map of Mars’ major volcanic regions created by the Arecibo Observatory in Puerto Rico (John Harmon et al., NAIC)

Even though we currently have several missions exploring Mars both from orbit and on the ground, there’s no reason that robots should be having all the fun; recently a team of radio astronomers aimed the enormous 305-meter dish at Puerto Rico’s Arecibo Observatory at Mars, creating radar maps of the Red Planet’s volcanic regions and capturing a surprising level of detail for Earth-based observations.

The team, led by John Harmon of the National Astronomy and Ionosphere Center, bounced radar waves off Mars from Arecibo’s incredibly-sensitive dish, targeting the volcanic Tharsis, Elysium, and Amazonis regions. Depolarized radar imagery best reveals surface textures; the rougher and less uniform a surface is, the brighter it appears to radar while smooth, flat surfaces appear dark.

What the radar maps portray are very bright — and therefore rough — areas on most of the major volcanoes, although some regions do appear dark, such as the summit of Pavonis Mons.

This likely indicates a covering by smoother, softer material, such as dust or soil. This is actually in line with previous observations of the summit of Pavonis Mons made with the HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter, which showed the summit to appear curiously soft-edged and “out-of-focus”, creating a blurry optical illusion of sorts.

It’s thought that the effect is the result of the build-up of dust over millennia, carried across the planet by dust storms but remaining in place once settled because the Martian wind is just so extremely thin — especially at higher altitudes.

The team also found bright areas located away from the volcanoes, indicating rough flows elsewhere, while some smaller volcanoes appeared entirely dark — again, indicating a possible coating of smooth material like dust or solidified lava flows.

The resolution of the radar maps corresponds to the wavelength of the signals emitted from Arecibo; the 12.6 centimeter signal allows for surface resolution of Mars of about 3 km.

The team’s paper was published in the journal Icarus on July 25. Read more on the Red Planet Report here.

What Has the Kuiper Belt Taught Us About The Solar System?

Over 4 billion miles (6.7 billion km) from the Sun, the Kuiper Belt is a vast zone of frozen worlds we still know very little about. Image: Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute (JHUAPL/SwRI)

Today marks the 20th anniversary of the discovery of the first Kuiper Belt Object, 1992QB1. KBOs are distant and mostly tiny worlds made up of ice and rock that orbit the Sun at incredible distances, yet are still very much members of our Solar System. Since 1992 over 1,300 KBOs have been found, and with NASA’s New Horizons spacecraft speeding along to its July 2015 rendezvous with Pluto and Charon (which one could argue are technically the first KBOs ever found) and then onwards into the Belt, we will soon know much more about these far-flung denizens of deep space.

But how has the discovery of the Kuiper Belt — first proposed by Gerard Kuiper in 1951 (and in a fashion even earlier by Kenneth Edgeworth) — impacted our current understanding of the Solar System? New Horizons Principal Investigator Alan Stern from the Southwest Research Institute recently discussed this on his mission blog, “The PI’s Perspective.”

First, Stern lists some of the surprisingly diverse physical aspects of KBOs that have been discovered so far:

  • Some are red and some are gray;
  • The surfaces of some are covered in water ice, but others (like Pluto) have exotic volatile ices like methane and nitrogen;
  • Many have moons, though none with more known moons than Pluto;
  • Some are highly reflective (like Pluto), others have much darker surfaces;
  • Some have much lower densities than Pluto, meaning they are primarily made of ice. Pluto’s density is so high that we know its interior is about 70% rock in its interior; a few known KBOs are more dense than Pluto, and even rockier!

But although these features are fascinating in themselves, just begging for further exploration, Stern notes that there are three very important lessons that the Kuiper Belt has taught us about the Solar System:

1. Our planetary system is much larger than we had ever thought.

“In fact, we were largely unaware of the Kuiper Belt — the largest structure in our solar system — until it was discovered 20 years ago,”  Stern writes. “It’s akin to not having maps of the Earth that included the Pacific Ocean as recently as 1992!”

2. Planetary locations and orbits can change over time.

“This even creates whole flocks of migration of planets in some cases. We have firm evidence that many KBOs (including some large ones like Pluto), were born much closer to the Sun, in the region where the giant planets now orbit.”

3. Our solar system, and likely others as well, was very good at making small planets.

“Today we know of more than a dozen dwarf planets in the solar system, and those dwarfs already outnumber the number of gas giants and terrestrial planets combined. But it is estimated that the ultimate number of dwarf planets we will discover in the Kuiper Belt and beyond may well exceed 10,000. Who knew?”

And with a little jab at the whole Pluto-isn’t-a-planet topic, Stern asks: “And which class of planet is the misfit now?”

Read: Was Pluto Ever REALLY a Planet?

The discovery of the Kuiper Belt has shown us that our solar system — and very likely planetary systems across the galaxy, even the Universe — aren’t neat and tidy things that can be easily summed up with grade-school models or chalkboard diagrams. Instead they are incredibly diverse and dynamic, continually evolving and consisting of countless, varied worlds spanning enormous distances… yet still connected through the ever-present effects of gravity (not to mention the occasional-yet-unavoidable collision.)

“What an amazing set of paradigm shifts in our knowledge the Kuiper Belt has brought so far. Our quaint 1990s and earlier view of the solar system missed its largest structure!”

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.”

Curiosity flexed her mighty robotic arm for the first time on Monday (Aug. 20) and aimed the hand-like tool turret squarely at Mount Sharp, her ultimate driving destination.

If you want to see exactly where Curiosity is headed and why she was sent to Gale Crater, just take a look at the new mosaic assembled by Ken Kremer and Marco Di Lorenzo.

Curiosity is pointing with her robotic arm right at Mount Sharp, the huge 18,000 foot tall (5.5 kilometer) mysterious mound that covers the center of the 96 mile (154 km) wide crater. Our mosaic was prominently featured on the front page of NBC News and in a new article by Alan Boyle – here

The layered sediments in Mount Sharp could unveil the geologic history of Mars stretching back billions of years and reveal why the planet transitioned from an ancient, wet period of flowing liquid water on the surface to the dry, desiccated era of today.

As Curiosity unstowed and raised the 7 foot long (2.1 m) arm and reached towards Mount Sharp, the mast mounted navigation cameras on her head snapped a series of black and white images that included the shadow of NASA’s newest Martian robot. The 6 wheeled, car-sized rover made a harrowing pinpoint touchdown barely 2 weeks ago.

The arm is critical to the success of the mission because it will be used to maneuver a sophisticated turret, mounted at the arms terminus and laden with scientific instruments. It weighs a hefty 66 pounds (30 kg) and is about 2 feet in diameter. The turret includes a high resolution focusable color camera, a drill, an X-Ray spectrometer, a scoop and mechanisms for sieving and portioning samples of powdered rock and soil.

“We continue to hit home runs. We unstowed the robotic arm and took a look at the tools on the end of the arm,” said Curiosity Mission Manager Michael Watkins of NASA’s Jet Propulsion Lab (JPL) at a news briefing on Tuesday, Aug. 21. “It’s kind of a Swiss army knife there where we have a lot of instruments. We wanted to make sure all of that was working by doing these first motor checks. All of that went successfully.”

Watkins said the team was thrilled to finally see images of the arm deployed on Mars after seeing thousands of engineering test images.

“We have looked at images thousands of times in our test environment and I always see the walls of the test lab there.Now to see the arm out there deployed with Mars out there in the background is just a great feeling.”

The next step is more tests to confirm the arms utility and movements and calibrate the instruments . “We will fully check out the arm, drill and processing unit,” said Louise Jandura of JPL, sample system chief engineer for Curiosity, at the briefing. “The arm has already performed all these motions on Earth, but in a different gravity condition and that gravity does matter. Our turret at the end of the arm weighs as much as a small child and the differences in gravity change the amount of sag at the end of the arm. We want to be able to fine tune these end-point positions. So it will take some time to put the arm through all its paces.”

What’s more is that Curiosity is wiggling her wheels and is all set to make her first martian test drive on Wednesday.

“Late tonight, we plan to send Curiosity the commands for doing our first drive tomorrow,” said Watkins. “Curiosity will drive about 10 feet, turn right and then back up so her rear wheels will wind up about where her front wheels are now. The cameras will photograph the tracks and evaluate the performance of Curiosity driving ability and the softness of the surface soil.”

The 1 ton mega robot is also equipped with the DAN (Dynamic Albedo of Neutrons) instrument provided by Russia to check for water bound into minerals as hydrates in the top three feet (one meter) of soil beneath the rover.

“Curiosity has begun shooting neutrons into the ground,” said Igor Mitrofanov of Space Research Institute, Moscow, principal investigator for DAN. “We measure the amount of hydrogen in the soil by observing how the neutrons are scattered, and hydrogen on Mars is an indicator of water.”

The mission goal is to ascertain whether the Red Planet was ever capable of supporting microbial life, past or present and to search for the signs of life in the form of organic molecules during the 2 year primary mission phase.
