The atlas has been launched to spread awareness about some of the landmark achievements of Indian Space Research Organisation (ISRO), and to engage those citizens who cannot understand English but are well versed in Hindi.

After success of many missions like Chandrayaan, Mangalyaan and ASTROSAT, ISRO has gained worldwide popularity and many foreign space agencies have shown interest in working with India.

This step will encourage young minds across the country to contribute to the field of space research, even if they do not possess the knowledge of English language.

The atlas will contain a compilation of images acquired by the Mars Colour Camera, and data collected by the five payloads of MOM. ISRO had also released a Mars Atlas in English on the occasion of Mangalyaan’s first anniversary on September 24, 2015. It provides a lot of detailed information about the different features of the red planet, such as its craters, moons, volcanic features, tectonic features and more.

” Flying Free Forever…” !!!

Back in 1981, in an effort to raise some quick funds, American Airlines introduced a $250,000 pass (about $641,000 today) that would allow customers to fly on its airlines for free for the rest of their lives. In 1990, they bumped the price to $600,000 (about $1.07 million today), and then in 1993 to $1.01 million (about 1.7 million today). Despite the sticker price, the airline has since admitted this is one of the costliest mistakes it has ever made.

Introduced in the summer of 1981, the unlimited “AAirpass” was originally envisioned as, to quote the airline’s former chief executive Robert Crandalll, something that “firms would buy for top employees” and it was thought that the scheme would bring in many millions of dollars in revenue in a very short timespan- essentially, easy money now to grow the company with, with future costs of having people use these passes being negligible to absorb. However, the AAirpass’ high cost resulted in a less than enthusiastic response from customers and in the end, only 66 passes were actually sold.

This is a shame for consumers, because those 66 customers got an amazing deal. As Crandall later noted, “It soon became apparent that the public was smarter than we were.”

According to the rather loose terms of the original AAirpass contract, customers who purchased one were entitled to free first class travel anywhere in the world and were given lifetime membership to American Airline’s Admirals Club, which grants priority boarding, same day booking and access to lounges across the world that offer free food and drink for members.

These benefits alone have seen some likening the unlimited AAirpass to “owning a fleet of private planes”. As one of the top frequent fliers, Steve Rothstein said, “A very fun Saturday would be to wake up early and fly to Detroit, rent a car and go to Ontario, have lunch and spend $50 or $100 buying Canadian things…” and then be back by dinner.

In another case, an individual travelled all the way to London 16 times in a single month, sometimes just staying long enough for a bite to eat before flying back home.

But it didn’t stop there. Savvy customers found ways to get even more out of their passes. You see, under the terms of the agreement, customers were still allowed to claim air miles on all flights they took, allowing those who used the service frequently (because why wouldn’t you?) to rack up literally millions of air miles in the space of just a handful of years, which they could give away to family and friends or in the cases of some customers, sell.

On top of this, because the AAirpass offered unlimited free travel, the airline were forced to absorb any and all fees customers incurred while using them (including taxes), meaning customers could literally book a dozen flights at a dozen different times for a single day and roll up to their airport whenever they felt like it, knowing that there would be no cancellation fees to pay for missing the other flights or additional duties or taxes to pay.

But we’re not done yet. On top of all this, American Airlines offered customers a chance to purchase a “companion pass” at a discount price (about 40% off), which granted all the same perks to anyone the original holder wanted as long as they flew together. Customers who opted for this particular upgrade utilised it in a number of impressively creative ways from booking an empty seat under a false name to score more elbow room in the already spacious first class, to ferrying friends and often random strangers across the world for free. In the case of a guy called, Steven Rothstein, he’d sometimes book two tickets for every flight he took just to surprise people at the airport with a free first class upgrade.

If you’re wondering how customers came up with all these ideas for bending the rules, many of them didn’t. A lot of the aforementioned tricks like booking multiple flights on a given day or an empty seat were often suggested to customers by people working for the airline itself as part of the complimentary booking service provided to Admirals Club members.

According to an internal report from American Airlines in 2007, the top unlimited AAirpass holders cost the airline in excess of a million dollars that year, each.Although, it would be interesting to actually see how they tallied this up, because if first class wasn’t sold out on a particular flight an AAirpass owner took, the airline wouldn’t actually lose money other than taxes, the price of in-flight consumables and the like, as it’s likely many of these customers wouldn’t have taken the flights in question had they not had the unlimited pass.

Regardless, the results of this internal report were alarming enough that it prompted American Airlines to sic its so-called revenue integrity unit onto owners of the passes in attempts to find something they’d done that constituted a breach of the AAirpass’ terms.

After pouring over the contracts and doing extensive investigations, American Airlines were able to successfully revoke the passes of a handful of the customers who’d “abused” the system the most. For instance, American tried to coerce certain people who’d been given a free ride courtesy of some of the more generous AAirpass owners into admitting that they’d paid for their tickets. In one such case, it was noted in an internal email from American Airlines that the individual in question who’d been given a ticket by AAirpass owner Jacques Vroom, “appears to be naive, without financial wherewithal, and most probably very anxious to return ‘home’”. So upon the young man checking in, he was taken to a private office and a former police officer working security for American Airlines questioned him, then offered him a free ticket home if he’d just admit he gave Vroom money for a ticket.

In another case concerning Vroom, the individual, one Sam Mulroy, was told his flight was canceled, but that he’d be given a new ticket, free of charge, if he’d just say he payed Vroom for the original ticket. Mulroy denied paying anything. When the offer of a free ticket didn’t work, American Airlines froze Mulroy’s Frequent Flier account. When Mulroy complained to American Airlines and the U.S. Department of Transportation that he felt he was being extorted by the airline, his account was unfrozen.

In the end, Vroom did indeed lose his pass when it was discovered in a subsequent lawsuit that he really had accepted payment for at least a few flights. Vroom, however, claimed the payments were for “business advice” (Vroom is a very successful marketing consultant), not for the tickets. However, Vroom’s lawyers noted that it shouldn’t matter whether he accepted payments or not, as American Airlines didn’t explicitly ban the practice of selling tickets in their “unlimited” pass contracts until three years after Vroom purchased his.

Other customers who lost their passes included a retired bond broker called Willard May who’d been very openly using his pass to ferry people across America for a fee for about two decades and the aforementioned Steven Rothstein for things like booking empty seats for his suitcase under the name “Bag Rothstein”.  While May decided against pursuing the matter in court, Rothstein did. He ultimately lost when a judge ruled he had indeed violated the terms of his contract. (Amusingly given how it all turned out, Rothstein once met the aforementioned American Airlines chief executive Robert Crandall during a flight, prompting the then CEO to send Rothstein a letter saying, “I am delighted that you’ve enjoyed your AAirpass investment. You can count on us to keep the company solid, and to honor the deal, far into the future.”)

At least two others were also found to have been in breach of their contracts, according to American Airlines, but their tickets were not revoked for undisclosed reasons.

For the curious, you can still purchase an AAirpass today, though not too shockingly, American Airlines no longer offers an unlimited version. The last time they did so was in 2004, three years before they’d realised exactly how much these passes were costing them every year. At that time, they offered the pass through Neiman-Marcus for $3 million (about $3.7 million today) per pass.  Despite that this would have still been a pretty good deal for a certain type of wealthy flyer or certain businesses to have such tickets at their disposal any time, nobody bought any at that price point.

Image of the Day…” Moon over Metéora monastery in Greece…”

Photo of rising moon on October 26, 2015 by Aimilianos Gkekas.

Last night’s rising moon behind a Greek monastery first settled in the 11th century.

Aimilianos Gkekas submitted this photo of last night’s moon – October 26, 2015 – rising behind theMetéora monastery in Greece. It’s one of the largest and most important complexes of Greek Orthodox monasteries in Greece, second only to Mount Athos. Both Metéora and Mount Athos are designated as UNESCO World Heritage Sites. UNESCO spoke of Metéora this way:

In a region of almost inaccessible sandstone peaks, monks settled on these ‘columns of the sky’ from the 11th century onwards.

There’s a hidden message written on the back of this family portrait that an Apollo astronaut left on the moon…

On April 20, 1972, Apollo 16 astronaut Charles Duke took his first steps on the moon. He was 36 at the time and is the youngest human in history to ever walk on the lunar surface.

But that’s not the only achievement of Duke’s that lives on in American history.

NASA John W. Young    Astronaut Charles M. Duke Jr., Lunar Module pilot of the Apollo 16 mission, is photographed collecting lunar samples at Station no. 1 during the first Apollo 16 extravehicular activity at the Descartes landing site.

While he was on the moon, he snapped this family portrait of him, his two sons, and his wife, which remains on the moon to this day.

DUKE

On the back of the photo Duke wrote:

“This is the family of astronaut Charlie Duke from planet Earth who landed on the moon on April 20, 1972.”

Here’s a clearer copy of the photo Duke gave us. On the far left is his oldest son Charles Duke III who had just turned seven. In the front in red is his youngest son, Thomas Duke, who was five. Duke and his wife, Dorothy Meade Claiborne, are in the background:

Portrait

“I’d always planned to leave it on the moon,” Duke told Business Insider. “So when I dropped it, it was just to show the kids that I really did leave it on the moon.”

The photo has since been featured in numerous popular photo books and is a great example of the “human side of space exploration,” Duke said.

When Duke was training to be an Apollo astronaut, he spent most of his time in Florida. But his family was stationed in Houston. As a result, the children didn’t get to see much of their father during that time.

“So, just to get the kids excited about what dad was going to do, I said ‘Would y’all like to go to the moon with me?’” Duke said. “We can take a picture of the family and so the whole family can go to the moon.”

More than 43 years have passed since Duke walked on the moon. And while the footprints that he made in the lunar soil are relatively unchanged, Duke suspects the photo is not in very good shape at this point.

“After 43 years, the temperature of the moon every month goes up to 400 degrees [Fahrenheit] in our landing area and at night it drops almost absolute zero,” Duke said. “Shrink wrap doesn’t turn out too well in those temperatures. It looked OK when I dropped it, but I never looked at it again and I would imagine it’s all faded out by now.”

Unfortunately, there is no way to determine just how faded the photo is because it’s too small for lunar satellites to spot.

Regardless, the photos “was very meaningful for the family,” Duke said. In the end, that’s all that matters, right?

Most Important Airplanes of All Time….

Ever since the Wright Brothers managed to get their Wright flyer airborne in 1903, the history of aviation has been dotted with a number of fascinating, landmark moments. This list will run through 14 of the most innovative, important and incredible airplanes ever to grace the skies, and tell the remarkable stories that made them such trailblazing groundbreakers.
1. Wright Flyer

The first plane to successfully take flight

The Wright Flyer is famous for being the first airplane to successfully take flight. Designed and built by pioneering inventors and entrepreneurs Orville and Wilbur Wright, it achieved its feat on the beaches of Kitty Hawk, when Orville Wright piloted the airborne plane for 12 short seconds, covering 120 feet. The flight may have been short, but it was to prove one of the moments of the century, and the brothers toured with their plane to show off their achievements to skeptical audiences throughout the world. It was during this tour that they flew about Le Mans in France and kick-started an aviation revolution across Europe that was to change the world.

2. Lockheed SR-71 Blackbird

The fastest airplane ever built

Important Airplanes

The Lockheed SR71 Blackbird was a long range, strategic reconnaissance aircraft operated by the US Air Force. Despite the fact that the Blackbird last flew in 1999, it still holds the record for the fastest flight speed ever recorded by an air-breathing manned aircraft at 2,193.2mph (3,529kph), a record that it has held – remarkably – since 1976. It once flew from London to New York (a distance of 3461.53 miles or 5,570.79km) in a ridiculously fast 1 hour 54 minutes in 1972, but Incredible speed was not the Blackbird’s only selling point. Throughout its commission it was also the highest flying plane in the world, capable of flying at an altitude of 85,069 feet or 25,929m. Of course, these attributes were not just for show, they helped the plane carry out crucial reconnaissance missions without detection, and evade missile fire when under attack.

3. Spitfire

The only plane to be manufactured throughout World War II

Important Airplanes

The Supermarine Spitfire was used extensively by the British Royal Air Force and other Allied countries during and beyond World War II. It has achieved iconic status for its role during the Battle of Britain when used by heavily outnumbered allied pilots to repel invaders from the German Luftwaffe. It was also produced in greater numbers than any other British aircraft, and was the only plane to be continuously manufactured throughout the war. It remained in production until 1954.

4. Benoist XIV

The first plane to fly a paying passenger

Important Airplanes

The Wright Brothers had proved that man’s dream of flying could become reality, but it was left to a tiny plane called the Benoist XIV to bring that dream to the paying market. The small plane was specifically designed in the hope of carrying passengers, but suffered problems in its early days. The summer of 1913 saw its first attempts to establish itself as a passenger plane, but the plan failed and the aircraft was a wrecked. It wasn’t until the winter of 1914 that the designer Thomas Benoist partnered with businessman Percival Fansler to offer commercial flights between the Florida cities of St Petersburg and Tampa. Finally, on January 10th 1914 pilot Tony Jannus flew former St Petersburg mayor Abram C. Pheil across the route for the princely sum of $400.00. Although regular flights were priced at $5.00, Pheil had paid more at auction for the honor of being the very first passenger.

5. de Havilland Comet

The first commercial jetliner

Important Airplanes

The de Havilland Comet is regarded as both a trailblazer and a tragedy by aviation historians. It was the first jet-powered passenger plane, capable of cruising at high altitudes  – and brought with it new levels of comfort and fresh possibilities for passenger flights. However, the Comet was beset by design faults leading to a number of awful accidents including three incidents in 1954 where planes broke up in mid-air. The tragedies ushered in a new era of extensive accident investigation and informed future aircraft design testing as engineers learned from the mistakes made by the Comet’s designers, including the use of catastrophically inadequate airframes.

6. Messerschmitt Me 262

The first jet-powered military plane

Important Airplanes

The German built Messerschmitt Me 262 become the first jet-powered fighter aircraft when it was first commissioned in 1942, bolstering the Luftwaffe fleet in the middle of World War II. Allied attacks on fuel supplies and problems with the reliability of the engines meant that its impact on the direction of the War was not as great as the German military hoped, and it was not in production for very long. However, its jet engines offered a degree of maneuverability and speed that was not replicated elsewhere at the time, and its design would inspire future military aircraft into the jet-powered age.

7. Gossamer Albatross

The first human powered aircraft to cross the English Channel

Important Airplanes

At first glance, you could be forgiven for thinking that the Gossamer Albatross was the product of aviation experimentation in the early 20th century. However, it was actually designed and built in the late 1970s. Paul B. McGready was the man behind the concept, and the Albatross was intended as a man-powered craft capable of long distance travel. On June 12th 1979, it achieved its ultimate goal when amateur cyclist and keen pilot Bryan Allen successfully flew it from England to France in 2 hours 49 minutes, reaching a top speed of 18mph. The super-lightweight composition of the Albatross has gone on to inspire the design of solar powered electric aircraft seen today.

8. Cirrus SR22

The first plane to have a life-saving ‘whole-airplane parachute’

Important Airplanes

The Cirrus SR22 has been the best selling single-engine, four-seater aircraft since it was introduced in 2001 – and for good reason. It features a composite construction fitted with a parachute that works on the entire plane. The parachute system has saved well over 100 lives over the course of the Cirrus’s production run, and has given confidence to budding pilots who can take the controls without the same levels of danger associated with other light aircraft. 19 year old Ryan Campbell flew in a Cirrus when he became the youngest pilot to fly around the world in 2014.

 

9. Concorde

Brought supersonic flights to the masses

Concorde is one of only two supersonic jets to ever carry commercial passengers and became synonymous with luxury travel and wealth. It first flew in 1969, but was not actually the first of its type – the Soviet built Tupolev Tu-144 beat it into flight by two months and the two types of plane were to be pitted in a commercial battle for years to follow. However, it was Concorde’s distinctive design that became best known throughout most of the world, and it remains an iconic symbol of aviation history today, even though it took its last flight (in a blaze of publicity) in 2003.

 

10. General Atomics MQ-1 Predator

The first military ‘drone’

Important Airplanes

The MQ-1 Predator was the first ‘unmanned aerial vehicle’ (more commonly known as ‘drone’) to be used in conflict. It is capable of being piloted remotely for up to 14 hours, monitoring its target and completing missions before returning to base. The plane has been used on reconnaissance missions primarily but is also capable of firing missiles, making it a trailblazer for a new era of drone warfare that is changing the face of military conflict.

 

11. Blériot XI

The first plane to cross the English Channel

Important Airplanes

Image: Bain News Service via Wikicommons

The Blériot XI was designed and piloted by Frenchman Louis Blériot, becoming the first aircraft to successfully fly the 22 miles of the English channel on July 25th 1909. The accomplishment was one of the foremost achievements of the ‘pioneer era’ of aviation in the early 20th century, and sees Blériot take his place alongside the likes of the Wright Brothers as one of the most influential innovators of early aircraft design. His achievements changed the way aviation was viewed and inspired the famous ‘Britain is no longer an island’ headline from British newspaper the Daily Express once news of the successful Channel crossing broke.

 

12. Boeing 747

The original high passenger capacity ‘Jumbo Jet’

Important Airplanes

Image: Flickr user Kevin White

The Boeing 747 was the original ‘jumbo jet’ built to transport more passengers than ever to faraway vacations. Much of the increase was provided by the ‘upper deck’, typically reserved for first class passengers. For 37 years it held the record for passenger capacity, after being originally introduced in 1970, and its design was even more impressive considering engineers had to hand-draw 75,000 technical sketches in the days before computers could do the job for them. The design was so good, in fact, that further advancements stalled and commercial passenger aviation remained unchanged for a number of years.

 

13. Bell X-1

The first aircraft to break the speed of sound

Important Airplanes

Image: U.S Airforce via Wikicommons

The Bell X-1 was the product of a research experiment by the National Advisory Committee for Aeronautics and the US Air Force, designed in 1944 and built in 1945. It was intended to break the sound barrier, and it did, achieving the first Mach 1 flight ever on October 14th 1947, in a plane pilot Chuck Yeager named Glamorous Glennis after his wife. The legacy of the Bell X-1 was vast as the research techniques informed future designs of supersonic aircraft and the flight data was crucial to American military design in the latter half of the 20th century.

 

14. Solar Impulse

The airplane powered by the sun

Solar Impulse

Solar Impulse represents the fruits of a Swiss led project to build a solar powered aircraft capable of flying long distances. The project has been in development since 2003 and has achieved a number of successes, included manned test flights, a continental flight across the USA and a re-design that saw the development of Solar Impulse 2, a second model that is currently on a round-the-world trip conducted in 13 stages over two years. As of the 23rd of October 2015, Solar Impulse 2 has completed 8 of those stages and sits in Hawaii ready to complete the final 5 stages of its journey back to Abu Dhabi, from where its journey began in March 2015.

The Beautiful Scenery of the Atacama Desert….The Driest Place in the World …!!!

The Atacama Desert in northern Chile is famous for being the driest place in the world. It is a virtually rainless plateau that sits across a location nearly 600 miles wide and is 50 times drier than the Death Valley in the United States, with an average rainfall of just 1 millimeter per year across the region, while some weather stations have never reported any precipitation since they started keeping records.

Atacama’s landscape has been carved by volcanic activity in the area and looks like no other. When you see the beautiful colors of the lagoons, volcanic peaks and vast salt basins that cover the desert, you will see why it is one of the most up-and-coming travel destinations in the world.

Given that the Atacama Desert is famous for being the driest place on Earth, it may come as a surprise to many to see a series of high altitude lagoons dotting across the area and providing a beautiful color contrast against the red volcanic landscapes. However, many hundreds of years ago, small periods of heavy rainfall caused water to accumulate in basins and create small lakes. Other lagoons formed from melting glaciers during the last ice age and have remained until this day. The lakes are generally extremely salty and given that more water evaporates in the area than falls, the lakes are technically drying up – although they will still be around for a while.

Many visitors flock to the area to experience its famous ‘otherworldly’ landscape. The comparisons with faraway lands are not just aesthetic either – they are grounded in science. Samples of soil taken in the desert have been found to have a similar composition to samples taken from Mars. NASA even uses the area to test roving vehicles and other instruments before they depart on missions for the red planet.

Despite the harsh conditions, nature (as it so often does) has found a way to thrive. Many varieties of weird and wonderful plant life add some color to the landscape, and a number of animal species have made the desert their home. Llama-like vicunas, small and furry viscachas and the elusive South American Grey Fox are among the mammals of the region, while a variety of birds can also be spotted including three different types of flamingos.

The desert was at the center of a huge land dispute between Chile and Bolivia in the 1800s. Because the area is home to the largest supply of sodium nitrate, it is a lucrative source of economic possibilities. The mining industry remains a big business today, and there are many abandoned towns that provide a reminder of the mining practices of yesteryear.  Chile won the land dispute, which is still the cause for some resentment across the border today.

The desert is largely isolated with a just a few small towns dotting the landscape. Visitors can arrive by air or overland into the largest town in the region – Calama – and most head for San Pedro de Atacama, from which many tours of the region can be arranged. The remoteness of the desert and lack of ambient light ensure it is a special place to be after night falls, offering not only spectacular sunsets above ethereal scenery, but also incredible views of the stars after nightfall. It is a one of the best places in the world to gaze into the milky way and it’s easy to arrange stargazing trips to please any budding astronomer.

This Made-In-India Chip Can Use TV Spectrum to Take the Internet to Rural India….

An Indian organization has come up with a technology that can help increase internet connectivity and take it to the rural parts of the nation as well.

A postal stamp-sized chip, called Pruthvi might have the potential to connect India’s rural population to the internet.

Developed by the Bangalore-based semiconductor firm, Saankhya Labs, the chip powers a system called Meghdoot that can use television White Space to transmit internet to many households.

White Space refers to the underutilised portion of the radio frequency spectrum. According a report in CNET, networks often leave a buffer between channels for safety purposes. Thus, large portions of the spectrum, usually in the 470 MHz to 790 MHz band, allocated for television broadcasting are unused or wasted, like the spectrum traditionally used for over-the-air transmission using TV towers and rooftop antennas. These spaces are at a lower frequency, and therefore a longer wavelength. This gives the signal a longer range, which can be used to deliver fairly low-speed Internet access over a wide area.

Saankhya Labs was founded in 2007 by Parag Naik, Hemant Mallapur and Vishwakumara Kayargadde. Pruthvi’s use is to allow Meghdoot to connect to a user-side modem to translate the white space signals to the more common internet bands that smartphones, tablets and computers use.

This technology can provide internet for up to a radius of 10-15 km depending on the height of the antenna tower and transmission power. The range can also be increased.

Saankhya labs is set to carry out field trials across the country in collaboration with IIT-Bombay, IIT-Delhi and IIT-Hyderabad. Discussions with Microsoft are also going on with the view of conducting trials in at Srikakulam in Andhra Pradesh.

“World over regulatory authorities are using or planning to use this spectrum for their respective connectivity programmes. India can take the lead in both technology and the markets for TV White Space-based broadband delivery,” Parag Naik, CEO and co-founder of Saankhya Labs, told The Economic Times.

The chip is crucial in today’s times when the country is taking various measures to increase the impact of digital India, and also when various technology companies are working on similar goals. Saankhya Labs has now joined the likes of Google, Facebook and Microsoft.

The Meghdoot product line is also compliant to the Wi-FAR standard. This makes it suitable for use in other countries as well. The organization is also engaged with partners in the Philippines, the US and Singapore for trials.

NASA launched a new website Monday so the world can see images of the full, sunlit side of the Earth every day. The images are taken by a NASA camera one million miles away on the Deep Space Climate Observatory (DSCOVR), a partnership between NASA, the National Oceanic and Atmospheric Administration (NOAA) and the U.S. Air Force.

Once a day NASA will post at least a dozen new color images of Earth acquired from 12 to 36 hours earlier by NASA’s Earth Polychromatic Imaging Camera (EPIC). Each daily sequence of images will show the Earth as it rotates, thus revealing the whole globe over the course of a day. The new website also features an archive of EPIC images searchable by date and continent.

The primary objective of NOAA’s DSCOVR mission is to maintain the nation’s real-time solar wind monitoring capabilities, which are critical to the accuracy and lead time of space weather alerts and forecasts from NOAA. NASA has two Earth-observing instruments on the spacecraft. EPIC’s images of Earth allow scientists to study daily variations over the entire globe in such features as vegetation, ozone, aerosols, and cloud height and reflectivity.

EPIC is a four megapixel CCD camera and telescope. The color Earth images are created by combining three separate single-color images to create a photographic-quality image equivalent to a 12-megapixel camera. The camera takes a series of 10 images using different narrowband filters — from ultraviolet to near infrared — to produce a variety of science products. The red, green and blue channel images are used to create the color images. Each image is about 3 megabytes in size.

“The effective resolution of the DSCOVR EPIC camera is somewhere between 6.2 and 9.4 miles (10 and 15 kilometers),” said Adam Szabo, DSCOVR project scientist at NASA’s Goddard Space Flight Center, Greenbelt, Maryland.

Since Earth is extremely bright in the darkness of space, EPIC has to take very short exposure images (20-100 milliseconds). The much fainter stars are not visible in the background as a result of the short exposure times.

The DSCOVR spacecraft orbits around the L1 Lagrange point directly between Earth and the sun. This orbit keeps the spacecraft near the L1 point and requires only occasional small maneuvers, but its orbit can vary from 4 to 15 degrees away from the sun-Earth line over several years.

EPIC was built by Lockheed Martin’s Advanced Technology Center, in Palo Alto, California. Using an 11.8-inch (30-centimeter) telescope and 2048 x 2048 CCD detector, EPIC measures in the ultraviolet, visible and near-infrared areas of the spectrum. The data from all 10 wavelengths are posted through a website hosted by the Atmospheric Science Data Center at NASA’s Langley Research Center, Hampton, Virginia. All images are in the public domain.

NASA uses the vantage point of space to increase our understanding of our home planet, improve lives, and safeguard our future. NASA develops new ways to observe and study Earth’s interconnected natural systems with long-term data records. The agency freely shares this unique knowledge and works with institutions around the world to gain new insights into how our planet is changing.
