Incredible Snapshots of Penguins !!!

 

An Australian photographer has captured incredible close-up images of penguins leaping out of the freezing ocean.

The colony of penguins was jumping for joy on leaving the water to warm up on the ice after hunting for food.

Photographer and marine scientist Frederique Olivier got his camera within a few feet of the flightless birds as they appeared to soar out of the ocean.

Frederique, 38, said: ‘You have to be incredibly patient to get the images of the right behaviour in the right light.

‘And you also have to cope with the temperature and winds as I gets down to minus-30 in the Antarctic winter.’

He was able to get close to the penguins as they weren’t bothered by his presence.

The adult penguins 'are all about breeding and raising chicks in the colony', so Mr Olivier had to be very careful not to disturb them

He added: ‘The penguins didn’t pay much attention to me – their mood varies and sometimes they are friendly but it is all about breeding and raising chicks in the colony.

‘They make you feel humble because they are incredibly adapted to the environment that they are in, whereas it is a challenge for us to survive.

‘It’s sometimes hard for them too so we have to be very careful not to disturb them.’

Image of the Day… Frosty Slopes on MARS…!!!

This image of an area on the surface of Mars, approximately 1.5 by 3 kilometers in size, shows frosted gullies on a south-facing slope within a crater.

At this time of year, only south-facing slopes retain the frost, while the north-facing slopes have melted. Gullies are not the only active geologic process going on here. A small crater is visible at the bottom of the slope.

The image was acquired on Nov. 30, 2014, by the High Resolution Imaging Science Experiment (HiRISE) camera, one of six instruments on NASA’s Mars Reconnaissance Orbiter. The University of Arizona, Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., Boulder, Colorado. NASA’s Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter Project for NASA’s Science Mission Directorate, Washington.

Image of the Day…” Holiday Lights On the Sun …” !!!

Holiday Lights on the Sun: Imagery of a Solar Flare

The sun emitted a significant solar flare, peaking at 7:28 p.m. EST on Dec. 19, 2014. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground, however — when intense enough — they can disturb the atmosphere in the layer where GPS and communications signals travel. This flare is classified as an X1.8-class flare. X-class denotes the most intense flares, while the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three times as intense, etc.

America to Australia in 6 Hours !!!

 

From America to Australia in Under 6 Hours

Just 100 years ago, getting from America to Europe was a voyage that took several days by ocean liners. With the invention of airplanes, that travel time was significantly shortened to under 24 hours. At the apex of the era of transatlantic flight, the Concorde was able to fly 100 passengers at mach 2.0 speeds from New York to London in just over 3.5 hours.

Now, the European Space Agency (ESA) just greenlighted the next stage of modern transportation – the hypersonic flight. The ESA has approved a new round of funding to project LAPCAT (Long-Term Advanced Propulsion Concepts and Technologies).
Hypersonic Plane

Ignoring its funny name, the new plane will fly at mach 5.0 speeds (that’s five times the speed of sound!), using liquid hydrogen engines. The planes will be able to travel from England to Australia in four hours, carry 300 passengers and even fly to space in just 15 minutes.

The new kind of engine is being developed by the British company Reaction Engines, who is said to invest over 60 million GBP in the development, and are going to start builing a full-scale prototype engine.

Hypersonic Plane

Current jet engines require that airplanes carry liquid oxygen as a coolant because in speeds beyond mach 3.0 the engines cannot use external oxygen for cooling. The new type of engine can use external oxygen freely, allowing it to cool down its engines from over 1,000°c (1,832°f) to -150°c (-328°f) in a fraction of a second.
Hypersonic Plane

Experts are hailing this development as the biggest advancement in aviation since the invention of the jet engine. The cost of a single plane is estimated to be a whopping $1.1 Billion and will have no windows.

 

Hypersonic passenger plane LAPCAT A2 explainer

 

The Long-term Advanced Propulsion Concept and Technologies (LAPCAT) was developed by British company Reaction Engines Limited (REL) and funded by the European Space Agency (ESA). The 139-meter long hypersonic plane has four liquid hydrogen-powered Synergistic Air-Breathing Rocket Engine (SABRE) engines and can carry up to 300 passengers.
It can travel up to 6,100 kilometer per hour – five times faster than the Airbus A380. By using liquid hydrogen as fuel instead of fossil fuel it is also greener and would only produce water vapor and nitrous oxide instead of carbon emissions.

Coldest Village on Earth … Now You will Realise That Your City or Town is a Paradise !!!

The Coldest Village on Earth !!!

If you think that the winter where you live is cold, the people in the village of Oymyakon, Russia will have a good chuckle at your expense. Located in the heart of Siberian, Oymyakon is considered to be the coldest inhabitable place in the world. With a temperature record of −90°f (−67°c) back in 1933, and an average of −60°f (−50°c) in January, it’s easy to see why.

When Amos Chappel, a photographer from New-Zealand, travelled to this frozen location, he brought back incredible pictures depicting the daily lives of the 500 inhabitants of this extraordinary village.

Astronaut’s-Eye View of NASA’s Orion Spacecraft Re-entry…

New video recorded during NASA’s Orion return through Earth’s atmosphere provides viewers a taste of what the vehicle endured as it returned through Earth’s atmosphere during its Dec. 5 flight test.

New video recorded during the return of NASA’s Orion through Earth’s atmosphere this month provides a taste of the intense conditions the spacecraft and the astronauts it carries will endure when they return from deep space destinations on the journey to Mars.

Among the first data to be removed from Orion following its uncrewed Dec. 5 flight test was video recorded through windows in Orion’s crew module. Although much of the video was transmitted down to Earth and shown in real time on NASA Television, it was not available in its entirety. Also, the blackout caused by the superheated plasma surrounding the vehicle as it endured the peak temperatures of its descent prevented downlink of any information at that key point. However, the cameras were able to record the view and now the public can have an up-close look at the extreme environment a spacecraft experiences as it travels back through Earth’s environment from beyond low-Earth orbit.

The video begins 10 minutes before Orion’s 11:29 a.m. EST splashdown in the Pacific Ocean, just as the spacecraft was beginning to experience Earth’s atmosphere. Peak heating from the friction caused by the atmosphere rubbing against Orion’s heat shield comes less than two minutes later, and the footage shows the plasma created by the interaction change from white to yellow to lavender to magenta as the temperature increases.

As Orion emerges safely on the other side of its trial by fire, the camera continues to record the deployment of the series of parachutes that slowed it to a safe 20 mph for landing and the final splash as Orion touched down on Earth.

NASA's Orion spacecraft is viewed by media at NASA's Kennedy Space Center, Fla. on Dec. 19, 2014.

Orion made the 8-day, 2,700 mile overland trip back to Kennedy from Naval Base San Diego in California. Analysis of date obtained during its two-orbit, four-and-a-half hour mission Dec. 5 will provide engineers detailed information on how the spacecraft fared. The Ground Systems Development and Operations Program led the recovery, offload and transportation efforts.

Orion was then retrieved by a combined NASA, U.S. Navy and Lockheed Martin team and carried back to shore aboard the Navy’s USS Anchorage. After returning to shore, it was loaded on to a truck and driven back to NASA’s Kennedy Space Center in Florida, where it arrived on Thursday.

Orion traveled 3,600 miles above Earth on its 4.5-hour flight test – farther than any spacecraft built for humans has been in more than 40 years. In coming back from that distance, it also traveled faster and experienced hotter temperatures – 20,000 mph and near 4,000 degrees Fahrenheit, to be exact. Orion will travel faster and experience even higher temperatures on future missions, when it returns from greater distances, but this altitude allowed engineers to perform a good checkout of Orion’s critical systems – in particular its heat shield.

Orion’s flight test was a critical step on NASA’s journey to Mars. Work already has begun on the next Orion capsule, which will launch for the first time on top of NASA’s new Space Launch System rocket and travel to a distant retrograde orbit around the moon.

Image of the Day…Ice Berg in South Atlantic !!!

Big iceberg in South Atlantic

Satellites have detected an iceberg adrift in the South Atlantic Ocean. It’s big … but doesn’t meet the criteria for tracking or naming.

The Aqua satellite caught this image of the unnamed iceberg on December 3, 2014.  Image via NASA Earth Observatory.

On December 3, 2014, satellite images revealed a large iceberg – measuring about 165 square kilometers (64 square miles) – east of the southern tip of South America in the South Atlantic Ocean. This iceberg doesn’t meet the criteria for tracking or naming. NASA Earth Observatory said:

Only icebergs that have a side measuring at least 19 kilometers (12 miles) long are named and tracked by the U.S. National Ice Center. That means nearly round or square icebergs—like the one pictured above—can be quite large and still not meet the criteria for naming and tracking.

But it’s still a big iceberg and so interesting. Icebergs such as this one break off from Antarctica, but scientists aren’t sure exactly where on the continent this one broke away.

In that way, it’s different from iceberg B31, a much bigger iceberg, which broke away from Antarctica’s Pine Island Glacier in late 2013 and has been hugging the Antarctic continent since then. B31 is a whopping 240 square miles (over 600 square kilometers). NASA recentlyre-acquired it via satellite, and, although B31 does meet the criteria for tracking and naming, for now it remains in the Amundsen Sea near Antarctica, although free now of surrounding debris and sea ice.

Large icebergs like these pose a danger to ships. For example, in 2007, the MS Explorer, a small Canadian cruise ship, sank after striking an iceberg near the South Shetland Islands.

Read more about the even bigger iceberg B31.

Bottom line: Early December 2014 images of the large, nearly circular iceberg adrift in the South Atlantic Ocean. It’s big – 165 square kilometers (64 square miles) – but doesn’t meet the criteria for tracking or naming.
