” Forget the Internet….Soon There will Be OuterNet …” !!!

 

  • An ambitious project known as Outernet is aiming to launch hundreds of miniature satellites into low Earth orbit by June 2015
  • Each satellite will broadcast the Internet to phones and computers giving billions of people across the globe free online access
  • Citizens of countries like China and North Korea that have censored online activity could be given free and unrestricted cyberspace
  • ‘There’s really nothing that is technically impossible to this’

 

You might think you have to pay through the nose at the moment to access the Internet.

But one ambitious organisation called the Media Development Investment Fund (MDIF) is planning to turn the age of online computing on its head by giving free web access to every person on Earth.

Known as Outernet, MDIF plans to launch hundreds of satellites into orbit by 2015.

And they say the project could provide unrestricted Internet access to countries where their web access is censored, including China and North Korea.

The ISS could be a testbed for Outernet technology

Could our Internet one day be delivered from space?

The New York company plans to ask NASA to test their Outernet technology on the International Space Station (left) so that they can begin broadcasting Wi-Fi to web users around the world (right)

 

Using something known as datacasting technology, which involves sending data over wide radio waves, the New York-based company says they’ll be able to broadcast the Internet around the world.

The group is hoping to raise tens of millions of dollars in donations to get the project on the r

 

The Outernet team claim that only 60% of the world’s population currently have access to the wealth of knowledge that can be found on the Internet.

This is because, despite a wide spread of Wi-FI devices across the globe, many countries are unable or unwilling to provide people with the infrastructure needed to access the web.

The Outernet project is aiming to raise tens of millions of dollars to launch hundreds of miniature satellites known as cubesats to make their dream a reality

The company’s plan is to launch hundreds of low-cost miniature satellites, known as cubesats, into low Earth orbit.

Here, each satellite will receive data from a network of ground stations across the globe.

Using a technique known as User Datagram Protocol (UDP) multitasking, which is the sharing of data between users on a network, Outernet will beam information to users.

Much like how you receive a signal on your television and flick through channels, Outernet will broadcast the Internet to you and allow you to flick through certain websites.

THE OUTERNET PROJECT TIMELINE

By June of this year the Outernet project aims to begin deploying prototype satellites to test their technology

In September 2014 they will make a request to NASA to test their technology on the International Space Station

By early 2015 they intend to begin manufacturing and launching their satellites

And in June 2015 the company says they will begin broadcasting the Outernet from space

‘We have a very solid understand of the costs involved, as well as experience working on numerous spacecraft,’ said Project Lead of Outernet Syed Karim, who fielded some questions on Reddit.

‘There isn’t a lot of raw research that is being done here; much of what is being described has already been proven by other small satellite programs and experiments.

There’s really nothing that is technically impossible to this’

But at the prospect of telecoms operators trying to shut the project down before it gets off the ground, Karim said: ‘We will fight… and win.’

If everything goes to plan, the Outernet project aims to ask NASA for permission to test the technology on the International Space Station.

And their ultimate goal will be to beginning deploying the Outernet satellites into Earth orbit, which they say can begin in June 2015.

Fate of MH 370… Finally….

 

Malaysian authories are assuming beyond a reasonable doubt that the missing Malaysia Airlines Flight 370 has been lost in the Southern Indian Ocean, according to South China Morning Post reporter Danny Lee.

 

NBC News reports that Malaysia Airlines sent a text message to the relatives of the 239 passengers who were on board the plane saying “we have to assume beyond any reasonable doubt that MH370 has been lost and that none of those on board have survived. … We must now accept all evidence that  suggest the plane went down in the Southern Indian Ocean.”

Malaysia Prime Minister Najib Razak will announce the new developments at a press conference on Monday.

The U.S. Navy is now flying a black box detector to the area in hopes of recovering the cockpit voice recorder and flight data recorder. A U.S. Navy plane flying over the possible debris field detected two or three faint radar hits, according to NBC News reporter Bill Neely.

Families of the MH370 passengers are taking charter flights to Australia tonight, according to Sky News.

Both Chinese and Australian aircraft have spotted possible debris in the Indian Ocean. The Boeing 777 plane went missing on March 8 during a flight from Kuala Lumpur to Beijing. There were 239 people on board.

Military radar shows that the plane reportedly changed altitutde and dropped to about 12,000 feet after making a sharp turn off its planned flight path, CNN reports.

This could point to the pilots trying to save the plane after something catastrophic happened – dropping to a low altitude is a procedure pilots use when the plane loses pressure. Getting down to a low altitude can save passengers on board because there’s enough air in the atmosphere to keep everyone alive.

All the Airplanes that Have Mysteriously Vanished since 1948 …

All the airplanes that have mysteriously vanished since 1948

As this Bloomberg map shows, Malaysian flight 370 is not the first flight to mysteriously disappear. 83 flights have vanished since 1948—80 of them never to be found again (the dots in yellow). This map only includes flights capable of carrying more than 14 passengers.

Some more curious stats:

  • Five planes were missing in the famous Bermuda Triangle.
  • The DC-3 is the airplane with the higher count of disappearances: 19.
  • The average number of people missing: 13.
  • The average number of vanished flight per year: 1.2.

Is This the Most Plausible Theory on the Missing MH 370 Flight ?

A CANADIAN pilot with 20 years experience has a simple theory regarding the disappearance of flight MH370.

Chris Goodfellow, a veteran flyer, isn’t buying any of the complicated ideas that have been floated by aviation experts since the plane vanished 11 days ago.

In a lengthy Google+ post, Goodfellow argues that the missing Malaysia Airlines flight probably fell victim to a fire, not a hijacking.

He says the plane’s sudden left turn is the key piece of evidence.

“We old pilots were drilled to know what is the closest airport of safe harbour while in cruise,” he writes. “If something happens, you don’t want to be thinking about what you are going to do — you already know what you are going to do. When I saw that left turn with a direct heading, I instinctively knew he was heading for an airport.”

Goodfellow believe Captain Zaharie Ahmad Shahs was taking a direct route to Pulau Langkawi, a 3,962-metre airstrip with an approach over water and no real obstacles. If the plane had turned back towards Kuala Lumpur, it would have needed to cross a series of high ridges.

According to Goodfellow, an electrical fire could explain MH370’s failure to communicate.

“For me, the loss of transponders and communications makes perfect sense in a fire. And there most likely was an electrical fire,” he says.

“In the case of a fire, the first response is to pull the main busses and restore circuits one by one until you have isolated the bad one. If they pulled the busses, the plane would go silent.

“It probably was a serious event and the flight crew was occupied with controlling the plane and trying to fight the fire. Aviate, navigate, and lastly, communicate is the mantra in such situations.”

Goodfellow also floats the possibility of a fire being caused by an overheating tyre on the plane’s landing gear.

“Once going, a tyre fire would produce horrific, incapacitating smoke,” he writes.

“What I think happened is the flight crew was overcome by smoke and the plane continued on the heading, probably on George (autopilot), until it ran out of fuel or the fire destroyed the control surfaces and it crashed.

“You will find it along that route — looking elsewhere is pointless.”

The former pilot has not been convinced by other theories that suggest the plane was hijacked.

“There are many ways a pilot can communicate distress,” Goodfellow says. “A hijack code or even transponder code off by one digit would alert ATC that something was wrong. Every good pilot knows keying an SOS over the mike always is an option … So I conclude that at the point of voice transmission all was perceived as well on the flight deck by the pilots.”

Goodfellow suggests the pilots were unaware that the ACARS system was not transmitting, and says an electrical fire is more likely to have caused that problem than a deliberate shutdown.

He says the analysis offered by news outlets has been “almost disturbing”, and the plane’s pilots deserve better.

“There is no point speculating further until more evidence surfaces, but in the meantime it serves no purpose to malign pilots who well may have been in a struggle to save this aircraft from a fire or other serious mechanical issue,” he says.

“Captain Zaharie Ahmad Shah was a hero struggling with an impossible situation trying to get that plane to Langkawi. There is no doubt in my mind.”

Goodfellow may have no doubts about his theory, but other aviation experts do. Greg Feith, a former crash investigator with America’s National Transportation Safety Board, has told NBC News that a fire would have given the pilots time to communicate.

“I’ve seen those remarks. I’ve seen the articles. If there was an electrical fire on board, there still has to be a source,” Mr Feith said. “And you can’t take out the entire electrical system all in one fell swoop without really catastrophically compromising the structure of the aeroplane.

“Typically, with an electrical fire, you’ll have smoke before you have fire. You can do some troubleshooting. And if the systems are still up and running, you can get off a mayday call.”

” How Safe Flying Has Become … “

When Malaysian Airlines flight MH370 disappeared without a trace over Southeast Asia sometime Saturday, a persistent question quickly emerged: How could an airliner just vanish? But as the days continue to pass without any sign of the plane, we have been reminded that flight is a complex process that we now frequently take for granted. That’s right, maybe this whole flying through the air in a metal tube with wings thing isn’t as easy or simple as we make it look, and sometimes, albeitextremely rarely, it does go wrong.

From the beginnings of the remarkable achievement of human flight and the mysterious disappearance of American aviator Amelia Earhart, a number of seemingly unbelievable incidents have helped shape how we fly. Some of the following air incidents ultimately made airplane travel safer, but usually only after emphasizing the fact that the skies — and what we do in them — can sometimes be shockingly unpredictable. Perhaps it’s amazing that things almost always go right.
1. A commercial airliner went down over the Atlantic and wasn’t found for five days.

88368623

Crew members of a Brazilian frigate recover debris from Air France flight 447. 

A little after 10 p.m. on May 31, 2009, Air France Flight 447 took off from Rio de Janeiro, Brazil to make its way across the Atlantic to Paris’ Charles de Gaulle International Airportf. The Airbus A330-203 was carrying 216 passengers, as well as 12 crew members. The aircraft was last contacted at 2:10 a.m. on June 1. Five days later, wreckage of the plane finally began showing up in the Atlantic. All aboard were presumed dead and the cause of the crash remained largely undetermined until the plane’s flight data recorder and the cockpit voice recorder were recovered nearly two years later, about two miles under the ocean.

Analysis of the black boxes determined that Air France Flight 447’s autopilot failed and the pilots mistakenly raised the nose of the plane causing it to stall. The pilots were reportedly unaware of the stall and continued pulling up, which resulted in the plane eventually plummeting intact from 38,000 feet, falling at roughly 10,000 feet per minute. Experts concluded that the plane broke apart not in the air but upon impact with the Atlantic Ocean.

2. An American Airlines plane was stolen off a runway in Luanda, Angola and has never been seen again.

The stolen American Airlines plane, 14 years prior. 

It was 2003, and Ben Charles Padilla — airline mechanic, flight engineer and private pilot — was in charge of maintenance of a used Boeing 727 American Airlines plane(owned by a Miami airline leasing company), that had been sitting on the runway in Luanda, Angola at Quatro de Fevereiro Airport for a little over a year. On May 25, 2003, the plane inexplicably made its way down the runway, without authorization and with its transponder turned off. The FBI and CIA believe Padilla was at the controls, but reports vary as to how many people were with him upon takeoff. U.S officials suspect the plane was used for illegal activity, such as running drugs, guns or perhaps even crashed for insurance money, but no one is certain. As of today, the plane and Padilla remain missing.
3. An Australian pilot reported a UFO hovering above him mid flight. He and his plane are still missing.

Single engine Cessna craft similar to that flown by Valentich. 

In October 1978, Frederick Valentich was flying over Melbourne’s Bass Strait when he reported that an aircraft that he could not identify was hovering a thousand feet above him. The flight tower told Valentich they detected no other aircraft in the area. At about 7:12 p.m., Valentich told the tower the object was “hovering and it’s not an aircraft.” This was followed by 17 seconds of unidentified “metal scraping sounds” and then silence. Valentich and his Cessna 182L were never seen again.

Without the wreckage, we’ll never really know what happened, but subsequent reports suggest it is likely that Valentich became disoriented, possibly misjudged his altitude and crashed. Given that the disappearance took place over 30 years ago, and no wreckage has ever been found on land, it leads many to believe that Valentich must have gone down over water, which could conceivably hide a crashed plane indefinitely.
4. The roof of a commercial airliner blew off mid-flight, leaving passengers and crew exposed to the elements. The plane still managed to land safely.

Passengers recover as the exposed cabin of Flight 243 looms in the background. 

On April 28, 1988, Aloha Airlines Flight 243 was carrying passengers from Hilo to Honolulu, Hawaii on a Boeing 737-297 when an explosive decompression caused the roof just outside the cockpit to rupture, leaving a gaping hole through which debris from the aircraft and unsecured items from the cabin were rapidly sucked out. One flight attendant, Clarabelle Lansing, was also ejected from the plane, and her body was never found. She was the lone fatality in the catastrophic incident, which according to the NTSB, was caused by a structural failure in the fuselage due to age and stress on the 19-year-old aircraft. Others had different hypotheses, but following the NTSB’s report, safety inspection and construction standards were changed for this line of commercial airliner.
5. A pilot successfully crash-landed a 737 in the middle of the jungle after flying in the wrong direction upon takeoff.

A Varig 737 similar to the one piloted into the Amazon. 

Varig Flight 254 was supposed to be taking a plane full of passengers on the final leg of a flight from São Paulo to Belém, in Brazil, on Sept. 3, 1989. After completing a number of successful stopovers, the crew prepared for the home stretch, a short journey from Marabá to Belém. When the pilot went to input the heading for the final flight, he misread the coordinates, leading him to direct the plane to fly in the opposite direction, into an uninhabited section of the Amazon. The true extent of the mistake went unnoticed until it was too late, as the pilots attempted to find nearby airfields to land in when they couldn’t find the Belém runway. The plane eventually ran out of fuel and the crew was forced to take the aircraft down over an isolated stretch of rainforest.

The impact and ensuing disintegration of the plane led to eight fatalities. Survivors of the crash then hiked out of the jungle to retrieve help for their companions. A total of 13 were killed as a result of the incident.
6. A commercial jetliner went down in the ocean just short of its island destination. Out of 153 people on board, only one survived.

yemenia flight 626

French and Yemeni divers search the Indian Ocean for the wreckage of Yemenia Flight 626. 

Yemenia Flight 626, an Airbus A310-324, crashed into the Indian Ocean off the coast of the small island of Comoros on June 30, 2009. Thirteen hours after the crash, rescuers spotted 14-year-old Bahia Bakari clinging to debris in the ocean. Without a life vest and apparently unable to swim, Bakari was the only survivor of the flight, which also claimed the life of her mother. An investigation of the crash ultimately determined that the plane had gone down due to crew error.
7. The U.S. Navy shot down a commercial jet thinking it was an F-14.

The U.S.S. Vincennes. 

With the Iran-Iraq war still going strong in 1988, there was still a great deal of uneasiness in the Persian Gulf. Iran Air Flight 655 left from Tehran on its way to Dubai on July 3. Patrolling the Gulf that day was the USS Vincennes, a U.S. Navy guided missile cruiser. The U.S. claims that it attempted to make contact with the aircraft, which did not identify itself, and thus was forced to shoot down the plane using two surface to air missiles, killing all 290 on board.

The U.S. military has stated that it believed the Airbus A300 was actually an F-14 fighter jet, a much smaller and much faster aircraft. The lack of concrete reasoning for firing upon the aircraft, along with its historical opposition to Iran, did not paint the U.S. in a forgiving light. And though it has never admitted fault, the U.S. government paid the families of the deceased $61.8 million in restitution.
8. A plane veered off the runway shortly after takeoff, severing its wing and exploding onto a nearby highway.

northwest airlines flight 255

A flatbed truck hauls the remains of Northwest Airlines flight 255’s two engines. 

Northwest Airlines Flight 255 took off just outside of Detroit on August 16, 1987. The McDonnell Douglas MD-82 departed the runway shakily and veered off in one direction, severing the fuel-filled wing of the plane on a light pole. That ignited the plane as it crashed and broke apart on nearby Interstate 94. A total of 148 passengers and six crew members were killed in the accident. Two people on the ground were also killed. The lone survivor of the flight was a 4-year-old girl named Cecelia Cichan. She lost her mother, father and 6-year-old brother in the incident. It remains thedeadliest sole-survivor crash in the history of aviation.

9. A corporate jet had part of its wing and tail clipped by a commercial airliner — at 37,000 feet.

shocking flights

The Legacy 600 jet with part of its wing and tail clipped. 

New York Times travel writer Joe Sharkey was flying above the Amazon rainforest on September 29, 2006 in what he called an “uneventful and comfortable flight.”Suddenly, the $25 million Embraer Legacy 600 corporate jet he was flying in was hit. By what, no one knew. The passengers could only see that part of a wing was gone. And all this at nearly 40,000 feet in the air, above the Amazon. The pilots, unsuccessful in contacting anybody on the ground, desperately looked for a place to land. Finally, they located a hidden military base and miraculously brought the aircraft down safely.

Sharkey and the other passengers all celebrated and joked about their brush with death, wondering what might have hit them. Then news came. A Brazilian flight went missing right in the area where they had reported the collision. It was carrying 155 passengers. The two aircraft had somehow been traveling at the same altitude in opposite directions, in the same space, each at about 500 miles per hour.

The other craft turned out to be Gol Transportes Aéreos Flight 1907, a Boeing 737 traveling from Manaus, Brazil to Rio De Janeiro. According to crash reports, the Legacy 600’s left winglet (part of the wing that juts vertically off the wing’s tip) had collided with and sliced off nearly half of the Boeing 737’s left wing. This caused Flight 1907 to nose dive from 37,000 feet into an uncontrollable spin, which broke the aircraft apart in midair, sending all passengers and crew members to their death in the jungle below.

___________________________________________________________
All of these incidents were as tragic are they were unusual, which is perhaps why they are so fascinating. Flying in an airplane is seemingly inevitable. The airline industry has made it possible for us to jet coast to coast, continent to continent and everywhere in between, pretty much at the drop of a hat. And while the two million-plus passengers who board more than 30,000 flights every day in the U.S. (and no doubt others around the world) love to complain when things go wrong and flights are delayed or interrupted by crying babies, being involved in something like one of the incidents above seems almost unthinkable.

And that’s not by accident: The airline industry has continued to improve safety standards for both planes and broader flight protocols, ensuring that we almost always get from point A to point B without any real trouble, much less danger. You have a one-in-11 million chance of being killed in an airplane crash, meaning you’re much more likely to be eaten by a shark, or as some airline executives claim, more likely to die in the airport — and certainly while driving there — than on the plane itself.

Magnificent Mars !!!

Anthony Wesley captured this glorious telescope image of the planet Mars on March 6. He wrote on his Facebook page:

Some good seeing this morning for the first time in many weeks…. I nearly missed it as the forecast was for cloud and rain, but at 3 a.m. it was clear although I could see lightning off in the distance…

North polar cap at top left, Syrtis Major to the lower left, cloud over the Elysium volcanoes at upper right, still bright blue cloud in Hellas at bottom. A faint band of equatorial cloud is also visible.

When to see Mars in 2014

A few days earlier, he got this awesome shot of Mars’ two moons, Phobos and Deimos.

Anthony Wesley also caught both of Mars' moons - brighter and closer Phobos and fainter, more distant Deimos - on March 2, 2014.

Of the image above, he wrote:
