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.

Message For the Day…” God is above and beyond the limits of Time and Space…”

There is no compulsive rule that incarnations should occur only on the earth and in human form. Any place and any form can be chosen by the fully free. Whichever place and form promote the purpose of fulfilling the yearning of the devotee, that place and form are chosen by the will of God. God is above and beyond the limits of time and space. He is beyond all characteristics and qualities, and no list of such can describe Him fully. For Him, all beings are equal. The difference between man, beast, bird, worm, insect, and even a god is but a difference of the ‘vessel’ (upadhi). The one single God activates every vessel and gives rise to manifold consequences. God appreciates the consciousness of unity as the basic motive of acts. He doesn’t appreciate the activity itself being one without variety; activity must be suited to the various needs

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.

This Day In Space Science… Establishment of NASA Ames on 20 Dec 1939…

75th Anniversary of NASA Ames

December 20, 2014 marks NASA Ames Research Center’s 75th Anniversary. The center was established in 1939 as the second laboratory of the National Advisory Committee for Aeronautics, and was named for the chair of the NACA, Joseph S. Ames. It was located at Moffett Field in Sunnyvale, California, now at the heart of Silicon Valley. The Laboratory was renamed the NASA Ames Research Center with the formation of NASA in 1958.

This June 2, 1943 photograph shows the construction of the Ames full-scale 40- by 80-foot wind tunnel, with a side view of the entrance cone and a blimp in the background.

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.

The successful launch of GSLV Mark III makes ISRO self reliant in launching heavier communication satellites

The Indian Space Research Organisation on Thursday launched its first experimental suborbital flight.

This was the test launch for ISRO heaviest and upgraded rocket, the GSLV Mark III, which is carrying the Crew Module Atmospheric Re-entry Experiment (CARE).

The flight took off from ISRO’s space station Sriharikota, near Chennai. Here are five things you need to know about the GSLV Mark III mission.

1) After its successful Mars mission, this is ISRO’s next step to put a man in space.

2) The Rs 155 crore mission has twin purposes — the main purpose is to test the rocket’s atmospheric flight stability with around 4-tonne luggage. The second is to study the re-entry characteristics of the crew module called Crew Module Atmospheric Re-entry Experiment.

3) Other critical technologies are also to be developed for ISRO’s manned mission. These are being developed parallelly at other centres. But recovery of the capsule from out of atmosphere will be the first to be tested.

4) GSLV Mark III is the heaviest next generation rocket, conceived and designed to make ISRO self reliant in launching heavier communication satellites of INSAT-4 class, which weigh 4,500 to 5,000 kg. Once operational, this rocket will have the capability to ferry four-tonne class of Insat series of communication satellites, which are currently being launched through Arianespace.

5) This is the second mission of the GSLV rocket during the last four years after two such launches failed in 2010.

Is There Life on Mars ?… Question Remains….

Questions of life on Mars revive with methane spike

Curiosity rover has now measured a dramatic spike in methane, an organic chemical, in the Martian air, plus other organic molecules in a Martian rock.

The first definitive detection of Martian organic chemicals in material on the surface of Mars came from analysis by NASA's Curiosity Mars rover of sample powder from this mudstone target,

The mystery of whether Mars has or ever had life got a boost today (December 16, 2014) when NASA announced that its Curiosity rover – which landed on Mars in August, 2012 – has measured a tenfold spike in methane in the atmosphere around the rover. NASA scientists made the announcement at the annual meeting of the American Geophysical Union in San Francisco. The journal Science also published these results today.

Methane is an organic chemical, and it’s conceivable, although far from certain, methane-belching microbes on Mars might be responsible for the spike.

Overall, researchers said, methane levels recorded by Curiosity’s onboard Sample Analysis at Mars (SAM) are lower than expected.

However, for about a two-month period in late 2013 and early 2014, researchers did observe a temporary and dramatic increase in methane in the Martian air around the rover.

NASA scientists are quick to point out that the source of the methane on Mars could be either biological or non-biological. For example, a non-biological source of the methane might be an interaction between water and rock.

At the same time, for the first time ever, the rover has detected other organic molecules in a rock-powder sample collected by drilling into a rock on Mars, which scientists have dubbed Cumberland. Organic molecules, which contain carbon and usually hydrogen, are chemical building blocks of life (although they can exist without the presence of life). NASA says it’s the first definitive detection of organics in surface materials of Mars. These Martian organics could either have formed on Mars or been delivered to Mars by meteorites, scientists say.

Is there life on Mars today, or was there ever life on Mars? These results don’t prove either speculation. However, said John Grotzinger, Curiosity project scientist of the California Institute of Technology in Pasadena:

We will keep working on the puzzles these findings present. Can we learn more about the active chemistry causing such fluctuations in the amount of methane in the atmosphere? Can we choose rock targets where identifiable organics have been preserved?

NASA says that Curiosity is:

… one element of NASA’s ongoing Mars research and preparation for a human mission to Mars in the 2030s.

Read more about Curiosity’s measurement of a methane spike on Mars.

Bottom line: Mars Curiosity rover measures a dramatic spike in methane and detects other organic molecules in a rock-powder sample collected by the robotic laboratory’s drill.
