Image of the Day…Martian Lakebed …!!!

This evenly layered rock photographed by the Mast Camera (Mastcam) on NASA’s Curiosity Mars Rover shows a pattern typical of a lake-floor sedimentary deposit not far from where flowing water entered a lake.

The scene combines multiple frames taken with Mastcam’s right-eye camera on Aug. 7, 2014, during the 712th Martian day, or sol, of Curiosity’s work on Mars. It shows an outcrop at the edge of “Hidden Valley,” seen from the valley floor.  This view spans about 5 feet (1.5 meters) across in the foreground.  The color has been approximately white-balanced to resemble how the scene would appear under daytime lighting conditions on Earth. Figure A is a version with a superimposed scale bar of 50 centimeters (about 20 inches).

This is an example of a thick-laminated, evenly-stratified rock type that forms stratigraphically beneath cross-bedded sandstones regarded as ancient river deposits.  These rocks are interpreted to record sedimentation in a lake, as part of or in front of a delta, where plumes of river sediment settled out of the water column and onto the lake floor.

NASA’s Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, manages the Mars Science Laboratory Project for NASA’s Science Mission Directorate, Washington. JPL designed and built the project’s Curiosity rover.  Malin Space Science Systems, San Diego, built and operates the rover’s Mastcam.

” Miracles Of Aviation History …With Happy Endings” !!!

Dietmar Eckell travels the world to photograph plane wrecks where everyone survived. He told BBC Culture why he decided to find crashes with happy endings.

Fairchild C-82A Packet, Alaska

January 1965, Alaska. A Fairchild C-82 is flying above the Arctic Circle when it encounters trouble. “The plane’s electric system failed and they crash-landed in the night in the tundra forest, cutting down many trees. They survived at -45 degrees Celsius by making a big fire from the wood they had cut. It is very remote up there: they were really lucky that the fire was spotted by another plane three days later and they were rescued.” German photographer Dietmar Eckell is describing one of the stories he discovered while researching his Happy End project, which records plane crashes that had no fatalities. He has even been contacted by those who survived: raising the money to print a book of the photos last year, he was contacted by the pilot of this Fairchild C-82. “He sent me an email to thank me for writing down his story and documenting his plane almost 50 years after the crash.”

 

Cessna 310, Australia

Eckell became interested in documenting wrecks where everyone survived after he had his own crash: flying a paraglider with an engine to take aerial shots over the Mojave Desert in California, he went into a tailspin and landed alone with a broken ankle. “While recovering from surgery I had time to search the internet for crash landings in remote locations with no fatalities.” He makes sure they were happy endings before he documents them: “I found planes where all survived the landing but a few started walking and were never found – if [even] one passenger did not make it, the plane is not included in the series.”

Grumman Hu-16 Albatross, Mexico

He finds the planes online, via “pilot forums, archives, accident reports and websites about World War Two history”. Pinpointing the exact location can be tricky. “Once the story is confirmed I try to find it on Google Earth. If the resolution is not good enough I ask at the local airport and most of the time pilots can help. Sometimes I have to hire a plane to search from above. Then I hike out there.” This plane is on a beach 70km south of Puerto Escondido. Eckell photographed it in September 2010, six years after it crashed: “It was half sunk and already broken in two pieces. On the pictures I saw [online] from 2006 … the engines looked like they would still work. But in four years the Pacific had done massive damage.” He happened to be shooting when a storm was passing. “The clouds were changing every minute. The scenery looked unreal through the viewer of my camera … more like a painting – surreal – with different lines of clouds towards the horizon.” It might not be there for much longer. “With the force of the waves the wreck is disappearing fast.”

 

Bristol Type 170 Freighter, Northwest Territories, Canada

Eckell has even tracked down planes that locals don’t know about. “One time I needed a float plane to get to a lake 400km away and could not afford a charter. After three days I found a retired pilot who was willing to take me there – although he did not believe that I had the location of an abandoned plane that he had never heard of in his 30 years as a local pilot. He was very surprised when we found the plane in great condition resting on the side of the lake, where it had been since 1956.”

 

Avro Shackleton, Western Sahara

The journey on foot to a plane can be hard-going. “Physically the hikes through swamps with all your gear are tough because your feet are wet all day, there are mosquitos and every kilometre feels like 5km.” He remembers his attempt to reach this plane in Western Sahara as particularly dangerous. “It’s in an area that is controlled by Polisario rebels. After a 30-hour car ride from Morocco to Mauritania and a 26-hour ride on an ore train, I got to a mining town and there had to convince the local Polisario leader to take me over the border to the Western Sahara. I had the plane’s GPS location and we drove cross country to avoid getting caught by the Mauritanian military. We had a very old car and after an hour it developed a flat tyre; but everything worked out and I got great shots of an Avro Shackleton. What I found interesting was that the same rebel group also rescued the 19 passengers in 1994.”

 

Douglas C-53 Skytrooper, Australia

Happy End is part of a longer-term project, called Restwert. “It started in the days before GPS when I was riding my motorbike in the remote Sahara following track descriptions with a map and compass. Some of the described landmarks along the way were car wrecks.” After photographing these ‘landmark wrecks’, Eckell went on to document abandoned mobile homes in the Mojave Desert. “With my photography I try to create curiosity for the story behind the picture.” This is one of the planes he has photographed most recently. It was forced to land in 1942 when the pilot missed the airport and ran out of fuel.

 

 

 

 

 

 

Douglas C-47 Skytrain, Yukon, Canada

There is an eerie dissonance between the wrecks and the majestic landscapes in the background, one that Eckell exploits to tell his story. “My ‘restwert’ photography is about abandoned objects forgotten in nowhere. When viewers see a photograph of a plane resting on a mountain or a tank sitting on a coral reef they want to know what happened … ‘Restwert’ is German for ‘residual value’ – the material value is written off, but the beauty, stories, and associations they trigger remain. I document these objects before nature takes them back to preserve their memory.” Ten people survived when this plane flew into the side of a mountain in February 1950. Eckell has visited the site twice. “I spent two hours at the wreck and still cannot imagine how they survived in February 1950 with temperatures in the -40s up there.”

 

Curtiss C-46 Commando, Manitoba, Canada

He sees the wrecks as beautiful, both because they represent a happy ending and because many of the planes have survived the ravages of nature. “Old airplanes, like the DC-3 or Curtiss Commando, are design classics and timeless beauties. Aluminium does not erode so they still look pretty good even after 70 years in the bush.” Eckell draws on artists from a different age. “I was inspired by the shipwreck painters of the Romantic period and in my photography also look for dramatic skies, late light or fall colours.”

 

B-24 Liberator, Papua New Guinea

“The locals in Papua New Guinea called this wreck ‘Swamp Ghost’,” says Eckell, who photographed it in March 2013. “When we arrived a heavy rain started and we had to hide under the wing for over an hour.” Trying to get the shot he wanted from a high vantage point, he climbed a tree. “Soon after I noticed that it was the home of giant ants. By the time I could get to a decent shot position they were all over me and it was difficult to focus.” The B-24 was forced to land in a sago swamp in October 1943, after running low on fuel after a bombing mission. The crew successfully parachuted to the ground, and the two pilots were unhurt in the crash landing.

 

Curtiss C-46 Commando, Manitoba, Canada

“I was in Calgary documenting the abandoned Olympic Ski Jump,” says Eckell, describing his journey to photograph this plane, which crashed near Churchill in 1979. “I took my octocopter which got a lot of attention from the biologists on the train who work at the Polar Bear Research Centre in Churchill. It’s not a good idea to walk out to the wreck – this is polar bear country and they are hungry in summer because they haven’t eaten anything since the ice melted.” He got a lift from a local, and took the pictures quickly. “The plane is sitting on huge rocks – the crew was lucky to crash in November with snow softening the impact.”

Image of the Day…. Launch of Orion …

The United Launch Alliance Delta IV Heavy rocket, with NASA’s Orion spacecraft mounted atop, lifts off from Cape Canaveral Air Force Station’s Space Launch Complex 37 at at 7:05 a.m. EST, Friday, Dec. 5, 2014, in Florida. The Orion spacecraft will orbit Earth twice, reaching an altitude of approximately 3,600 miles above Earth before landing in the Pacific Ocean. No one is aboard Orion for this flight test, but the spacecraft is designed to allow us to journey to destinations never before visited by humans, including an asteroid and Mars.

Image of the Day…Full Circle Rainbow !!!

Rare and wonderful full-circle rainbow

In theory, any rainbow can be a full circle, but – from Earth’s surface – we typically see only the top part of a rainbow.

View larger. | Full circle rainbow was captured over Cottesloe Beach near Perth, Australia in 2013 by Colin Leonhardt of Birdseye View Photography.  He was in a helicopter flying between a setting sun and a downpour.   Used with permission.  Order prints of this photo.

Colin Leonhardt kindly gave us permission to publish this awesome full-circle rainbow photo, which was the Astronomy Picture of the Day on September 30, 2014. People often think they have seen full-circle rainbows, but what they are most commonly seeing are airplane gloriesor halos around the sun. It’s very rare to see a full-circle rainbow. You have to be up high to see one, and sky conditions have to be perfect. Remember … a true rainbow is seen when you’re looking opposite the sun, through a shower of rain.

Colin Leonhardt captured this full-circle rainbow over Cottesloe Beach near Perth, Australia in 2013. He was in a helicopter, flying between sunset and a shower of rain.

Notice the second rainbow – fainter and color-reversed – outside the first.

Order prints of this photo.

Bottom line: Beautiful photo of rare full-circle rainbow, captured from the air by Colin Leonhardt in Perth, Australia.

” Days of Darkness this December …? Of course NOT …”

Days of darkness this December? Of course not.

Heard the rumor that “NASA says” Earth will experience several days of total darkness in December 2014? Not true, of course.

Question: Will Earth experience six (or three) days of darkness in December, 2014?

Answer: No.

We at EarthSky have received many questions already about the so-called days of darkness supposedly announced by NASA and supposedly coming up in December, 2014. This rumor has spread like wildfire, as did the same rumor in 2011, which called for days of darkness caused by the erstwhile Comet Elenin. 2014’s version of the rumor apparently first began with this article from Hutzlers.com. The article states:

NASA has confirmed that the Earth will experience 6 days of almost complete darkness and will happen from the dates Tuesday the 16 – Monday the 22 in December. The world will remain, during these three days, without sunlight due to a solar storm, which will cause dust and space debris to become plentiful and thus, block 90% sunlight.

Oh, brother. Just reading that quote gives us a combination of heartburn plus giggles. Why? Let’s ignore for the moment that space scientists can’t yet predict when a solar storm will occur, although, in the hours leading up to one, they sometimes suggest a probability that one might occur. That aside, there’s never been an event where a solar storm created enough “dust and debris,” whatever that means, to darken Earth … at least not in living memory. Could such a thing even be predicted, sort of like Superman’s dad Jor-El predicted the explosion of planet Krypton (which also had never happened before)? Let’s remember for a moment that Superman was fiction, but, even given that, many other imaginary scientists on that imaginary planet Krypton were arguing that the explosion wasn’t really imminent. Likewise, here on our real Earth, a prediction of days of darkness caused by solar storms would be such outlandish science that scientists would argue about it up until the time it happened … or didn’t happen. NASA wouldn’t just suddenly “predict it,” in other words.

Before we go on, the inquiring reader may want to read what Hutzlers.com says about itself:

Huzlers.com is a combination of real shocking news and satirical entertainment to keep its visitors in a state of disbelief.

Well, they got that part right.

Needless to say, the NASA Earth Observatory website totally disavowed the hoax.

. Is Earth totally dark when it’s night for you? No. Earth is always half illuminated by sunlight. Notice the crescent of illumination on one edge in this photo. If you were on the other side of Earth when the images used in this composite were acquired, you’d see Earth shining brightly in reflected sunlight, aka daylight. Image via NASA/NOAA.
Is all of this a replay of the December, 2012 winter solstice hysteria?

We don’t know what it is about the December solstice, the Northern Hemisphere’s winter solstice, but it seems to inspire all kinds of pseudo-scientific claims and apocalyptic fantasies. The days-of-darkness theme appears to be a revival of sorts of the bogus galactic alignment prophesy, which did not take place – as expected – on the 2012 winter solstice.

Snopes.com, which has already investigated and debunked the supposed December, 2014 NASA Blackout Warning, recalled a 2012 prediction whereby:

The Earth will shift from the current third dimension to zero dimension, then shift to the fourth dimension. During this transition, the entire Universe will face a big change, and we will see a entire brand new world. The 3 days blackout is predicted to happen on Dec 23, 24, 25….

Okay then … moving on …

As Comet Elenin passed to within just 7 million kilometers of the STEREO (Behind) spacecraft, NASA rolled the spacecraft to take a look at it (Aug. 1, 2011) with its wide angle HI-2 instrument. Image credit: NASA
As Comet Elenin passed near the sun in 2011, it was supposed to block the sun and cause three days of darkness. Of course, it didn’t. That would have been far more difficult than, say, a mosquito blocking your car headlight. Image via NASA
Remember Nibiru, the fictitious planet, which was predicted to bombard the inner solar system and collide with our planet Earth in 2012?

When acute telescopic observers wondered why this huge planet wasn’t visible in the night sky by 2010, Nibiru proponents answered the challenge by claiming the discovery of Comet Elenin in December 2010 provided proof of Nibiru’s existence.

Moreover, prognosticators went on to say that Comet Elenin itself was to bring three days of darkness – which, of course, never came to pass. Meanwhile, Comet Elenin eventually disintegrated.

So will you experience three to six days of darkness in December, 2014? No … unless you live north of the Arctic Circle, which has continuous darkness in winter every December.

Bottom line: NASA did not predict – and December, 2014 will not have – three to six days of darkness.

” Astronaut Chris Hadfield Explains The Big Problem With The Mars One Mission”

If you haven’t heard, there’s a plan to start up a colony of humans living on Mars in the near future.

If the next decade goes as planned, the not-for-profit organization, Mars One, will launch a manned mission to Mars that will land the first human colony on the red planet in 2025.

Here’s the catch: Those who leave Earth for the 7-month-long ride in space will never return.

The four-member crew will learn to call Mars – a freezing, barren, lifeless planet – home. Forever.

That may sound great to the tens of thousands of people who applied, but Mars One is going about their grandiose plans all wrong according to retired Canadian Space Agency astronaut Chris Hadfield.

Right now, Mars One is focused more on raising funds and selecting crew members than developing the technology needed for the trip. And the technology, Hadfield told Elmo Keep, writing in Medium, is the most basic starting point for any space mission.

“There’s a great, I don’t know, self-defeating optimism in the way that this project has been set up,” Hadfield told Keep. “I fear that it’s going to be a little disillusioning for people, because it’s presented as if for sure it’s going to happen.”

So far, the company claims they’ve had more than 200,000 people apply, and are about to start interviews with 663 final candidates. Mars One says that they will gather the majority of money for the trip through crowd funding from a global reality television event.

The company anticipates that the trip to Mars will cost approximately $6 billion (that’s shockingly low compared to NASA estimates for a two-way trip to Mars and back costing roughly $100 billion.)

Although Mars One has visions of partnering with companies like SpaceX to procure the proper technology, so far its only contract is with Paragon Space Development Corporation to study initial life support systems.

Hadfield isn’t the only one doubting this project. Doubters at MIT have calculated that “living on Mars” will last only about 68 days before the colonists die.

In particular, Hadfield said, if you don’t have the specifications of the spacecraft, you can’t begin to select the people who will live and work in it.

“I want to see the technical specifications of the vehicle that is orbiting Earth,” Hadfield said. “I want to know: How does a space suit on Mars work? Show me how it is pressurized, and how it is cooled. What’s the glove design?”

What’s more, Mars should not even be a target for colonization at this point, according to Hadfield. Our sites should be set on a place much closer.

“We absolutely need to do it on the moon for a few generations,” Hadfield told Keep.

On average, the moon is about 600 times closer to Earth than Mars. That means if something goes wrong with a colony, we can dispatch help from Earth that will reach the Moon in a matter of hours instead of months. Developing a working moon colony would be an important first step to living on Mars.

NASA

Astronaut Eugene A. Cernan of Apollo 17 tests the Lunar Roving Vehicle on the moon.

Here’s a short list of what Hadfield told Keep we need to know before living on Mars:

  • How do you completely recycle your water?
  • How do you completely recycle your oxygen system?
  • How do you protect yourselves from radiation?
  • How do you not go crazy?
  • How do you set up the politics of the place and the command structure, so that when we get it wrong we won’t all die?

While the Mars One desire to get people excited about space travel again is noble – it has been more than 42 years since we last landed a human on anything in space besides the International Space Station. There’s a right way and a wrong way to go about landing people on other satellites throughout the solar system.

“It’s not a race, it’s not an entertainment event. We didn’t explore the world to entertain other people. We did it as a natural extension of human curiosity and matching capability,” Hadfield told Keep. “And that’s what will continue to drive us.”

Image of the Day…Bar-Headed Geese in India…!!!

Bar-headed geese in India

EarthSky Facebook friend Abhinav Singhai in India captured this evocative shot of bar-headed geese over Basai Wetlands, a well-known destination for birders near Delhi, India. He said there were hundreds of geese over the wetlands that day.

Thank you, Abhihav!

The bar-headed goose is a fascinating bird, by the way, and one of the world’s highest-flying birds. It’s been heard flying across Mount Makalu – the fifth highest mountain on Earth at 8,481 meters (27,825 ft). The British explorer George Lowe is said to have reported seeing bar-headed geese flying over Mount Everest – 8,848 meters (29,029 ft)! You’ll find mention of Lowe’s tale about the geese here.

According to Wikipedia, the bar-headed goose is:

… a goose that breeds in Central Asia in colonies of thousands near mountain lakes and winters in South Asia, as far south as peninsular India …

The bird is pale grey and is easily distinguished from any of the other grey geese of the genus Anser by the black bars on its head.

Vertical Farming @ Singapore !!!

 

According to most scientists, we are fast approaching a global food shortage. The amount of land used for agriculture is just not enough to meet the food demands of the global urban population. That is why creative means must be found to grow food in limited spaces. Nowhere is that problem more profound and noticeable than places like Singapore, where very little land is available. What did they do? They started farming UPWARDS…
