PASSENGERS on a Brazilian Airlines flight found themselves in a close call earlier this month after one of its jets unknowingly flew into a destructive hailstorm.

Brazilian TAM Airlines Flight JJ 3307 took off in Rio de Janeiro en route to the Brazilian city of Natal on February 9 and climbed to approximately 18,000 feet when the flight entered what has been described as a “cloud of hail”.

Local media Odia suggest lightning damaged the flight’s weather radar, steering the flight into dangerous territory and leaving its pilots powerless to know what lay ahead.

Reports indicate that as the plane was turning back, a hail strike hit, cracking the plane’s three-layered windscreen and crushing its nose. Pictures reveal the sheer power of the thunderstorm.

Despite the drama, the flight was able to make it to land safely within forty minutes.

No injuries were reported.

“In the path (the air) passed through a turbulent area and hail damage was not detected by radar,” TAM said in a statement.

“The landing was carried out at the Galeão International Airport, with complete safety for the passengers and crew.”

YOUR plane could soon be operated by remote control if the latest trial in Sweden takes off.

Örnsköldsvik airport in the northeast of Sweden has ditched its control tower and is now landing planes via remote control from an airport sitting 100km away. And there are plans for a similar system to come to Australia.

Air traffic controllers for Örnsköldsvik now sit in a computer simulated room at the larger Sundsvall airport surrounded by giant television screens beaming footage to them of Örnsköldsvik’s incoming planes.

The only airport in the world to be managed by remote control, it is called the Remote Tower System (RTS) and is being trialled in Sweden as a way of improving accuracy and cutting costs.

It works by streaming high definition images of incoming planes at Örnsköldsvik to a Remote Tower Control room based in Sundsvall. Using high tech cameras, sensors and microphones — the RTS collects data about the plane to provide a simulated digital visual to the controllers as well as surround sound audio of the incoming plane.

The technology has been designed by Saab, the Swedish defence and security company, who says it provides “enhanced situational awareness” for air traffic controllers.

New features include object tracking and alerting, night vision, image enhancement, onscreen display of plane statistics, runway incursion warnings and options for zooming and switching to infra-red view in thick fog and darkness.

Mikael Henriksson, the project manager of the RTS in Sundsvall, told NPR it’s a “paradigm shift” for the industry. “For the air traffic controller, this is like airline pilots going from propeller to jet,” he said.

NPR spoke to Erik Backman who runs the RTS in Sundsvall, who says he was dubious when he first saw the mock-up technology in 2004. However a decade later he says they’ve been landing planes remotely for months without any major problems.

The use of remote control towers has been explored by the aviation industry as a way of cutting costs at airports too quiet to warrant full time air traffic controllers.

Later this year a US airport, Leesburg Executive Airport in Virginia, will be installing the RTC, making it the first remote-controlled operated airport in the country.

This airport is operated by remote control... really?

Australia is also considering installing the technology with plans to control planes at Adelaide airport by air traffic controllers sitting in Melbourne, 700km away.

Rob Walker, spokesman for Airservices Australia, told the Adelaide Advertiser that the increase in air traffic across Australia requires an upgraded and centralised air traffic system.

He said this system would allow controllers monitoring aircraft in Adelaide to be based in Melbourne and aircraft in Cairns to be monitored from Brisbane.

“There is no change in the number of controllers but only where the service is delivered from … and safety is not an issue,’’ he said. Changes will not be made until 2017.

Selfie of Curiosity ‘Mojovae’ Site on Mount Sharp of MARS !!!!

 

This self-portrait of NASA’s Curiosity Mars rover shows the vehicle at the “Mojave” site, where its drill collected the mission’s second taste of Mount Sharp.

The scene combines dozens of images taken during January 2015 by the Mars Hand Lens Imager (MAHLI) camera at the end of the rover’s robotic arm.  The pale “Pahrump Hills” outcrop surrounds the rover, and the upper portion of Mount Sharp is visible on the horizon.  Darker ground at upper right and lower left holds ripples of wind-blown sand and dust.

An annotated version, Fig. A, labels several of the sites Curiosity has investigated during three passes up the Pahrump Hills outcrop examining the outcrop at increasing levels of detail. The rover used its sample-collecting drill at “Confidence Hills” as well as at Mojave, and in late February was assessing “Telegraph Peak” as a third drilling site.

The view does not include the rover’s robotic arm.  Wrist motions and turret rotations on the arm allowed MAHLI to acquire the mosaic’s component images. The arm was positioned out of the shot in the images, or portions of images, that were used in this mosaic. This process was used previously in acquiring and assembling Curiosity self-portraits taken at sample-collection sites “Rocknest” (http://photojournal.jpl.nasa.gov/catalog/PIA16468), “John Klein” (http://photojournal.jpl.nasa.gov/catalog/PIA16937) and “Windjana” (http://photojournal.jpl.nasa.gov/catalog/PIA18390).

Curiosity used its drill to collect a sample of rock powder from target “Mojave 2” at this site on Jan. 31, 2015.  The full-depth, sample-collection hole and the shallower preparation test hole beside it are visible in front of the rover in this self-portrait, and in more detail at http://photojournal.jpl.nasa.gov/catalog/PIA19115 .  The Mojave site is in the “Pink Cliffs” portion of the Pahrump Hills outcrop. The outcrop is an exposure of the Murray formation, which forms the basal geological layer of Mount Sharp.  Views of Pahrump Hills from other angles are at http://photojournal.jpl.nasa.gov/catalog/PIA19039 and the inset at http://mars.jpl.nasa.gov/msl/multimedia/images/?ImageID=6968 .

The frames showing the rover in this mosaic were taken during the 868th Martian day, or sol, of Curiosity’s work on Mars (Jan. 14, 2015).  Additional frames around the edges to extend the amount of terrain included in the scene were taken on Sol 882 (Jan. 29, 2015).  The frames showing the drill holes were taken on Sol 884 (Jan. 31, 2015).

For scale, the rover’s wheels are 20 inches (50 centimeters) in diameter and about 16 inches (40 centimeters) wide.  The drilled holes in the rock are 0.63 inch (1.6 centimeters) in diameter.

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

” You Think Our City Roads are More Congested ? … Watch this Video clip !!!”

 

Both Europe 24 and North Atlantic Skies were designed to give an overview of the daily complexity and volumes of air traffic across the UK and Europe and to do so in a way that was cinematic and exciting to watch. I think we were able to do that to great effect, but we now want to take you a little deeper.

We are therefore very excited to publish UK 24 – your guided tour to some of what makes UK aviation work.

Our airspace is busy, complex and there is a lot going on. Each year we manage around 2.2 million movements, peaking at over 8,000 a day (although there are around 7,000 on this particular day), with only 5.5 seconds delay per flight attributable to NATS. Obviously there are the flows of large aircraft from the airports into and out of the UK, but there is also a lot of activity outside controlled airspace. UK 24 is designed to help visualise the breadth and depth of UK aviation and why airspace is such an important asset.

The day starts with the bow wave of transatlantic traffic heading towards the UK on their organised and separated tracks. This is quickly joined by traffic from Europe and the first waves of departures from UK airports. Over a short period of time the traffic levels grow to show the main trunk roads of airspace as well as the hubs around London, Manchester and central Scotland.

We then move to give a unique view of the holding stacks over London and how they are a fundamental part of the Heathrow operation, providing the constant flow of traffic that makes it the world’s busiest dual runway airport with 1,350 movements a day.

Our tour then take us around the UK, including the other major airports, our two control centres in Swanwick and Prestwick, some general aviation traffic and examples of military training off the east coast of England and near to North Wales. We then dwell on the spider’s web of helicopter tracks that originate from Aberdeen, taking people and vital supplies to and from the North Sea oil and gas rigs.

We hope you enjoy this insight into the complexity and beauty of a day of UK air traffic and the value of airspace as the invisible infrastructure that makes it all work.

Value of aviation to the UK economy

The aviation sector and its supply chain generates over £20bn per year in economic output and directly employs circa 220,000 people. At Heathrow alone, goods worth £133 billion were shipped in and out last year, more than the combined value of goods transiting through the UK’s two largest ports, Felixstowe and Southampton.

Aviation is on average a much more productive sector than the rest of the economy; each pound spent on upgrading our aviation infrastructure is expected to generate over £5 in return. In addition aviation is a significant growth sector within key regions for UK trade, for example China, the Middle East and Turkey have ambitious plans to more than double their capacity.

Without additional capacity in the UK, we risk the rapid growth in traffic and its associated commerce being focused elsewhere.

Image of the Day…. ISS astronauts’ Space Walk Today… Feb 25…

Today’s spacewalk – the 2nd of 3 planned – began at 7:10 a.m. EST (1210 UTC) and will last 6.5 hours. This post has links to today’s live coverage, plus spectacular images from Saturday’s spacewalk.

Today – February 25, 2015 – beginning at 7:10 a.m. EST (1210 UTC), International Space Station (ISS) astronauts are performing the second of three spacewalks to prepare the orbiting laboratory for future arrivals by U.S. commercial crew spacecraft. NASA TV coverage has begun and will go until 2 p.m. EST (1900 UTC) Wednesday. Watch here

NASA astronauts Barry Wilmore and Terry Virts completed the first spacewalk on February 21 and the third is scheduled for Sunday, March 1.

The spacewalks are designed to lay cables along the forward end of the U.S. segment to bring power and communication to two International Docking Adapters slated to arrive later this year. The new docking ports will welcome U.S. commercial spacecraft launching from Florida beginning in 2017, permitting the standard station crew size to grow from six to seven and potentially double the amount of crew time devoted to research.

Ground controllers have maneuvered the space station’s large robotic arm Canadarm2 in place for work planned for Wednesday’s spacewalk. Spacewalkers Barry Wilmore and Terry Virts will start their spacewalk at 7:10 a.m. EST to lay more cables and lubricate one of Canadarm2’s two latching end effectors, which serve as tip or base for the robotic arm. They will also prepare the Tranquility module for the relocation of the Permanent Multipurpose Module and the new Bigelow Expanded Activity Module later this year.

All three spacewalks are in support of the long-planned ISS reconfiguration from its current configuration, which was designed to support visiting Space Shuttles, to its new configuration optimived for future visiting commercial crew and cargo vehicles.

While cargo vehicles attach to the ISS using the process of berthing, whereby they are captured with the station’s robotic arm and positioned below a berthing port prior to being bolted into place, commercial crew vehicles will not use this method.

This is because the process of un-berthing takes a long time to complete, since cables and ducting between the visiting spacecraft and the ISS must first be manually disconnected, control boxes installed, hatches closed, and then the visiting spacecraft must be maneuvered away from the station with the robotic arm.

This means that berthing ports cannot support a rapid evacuation of crew from the ISS should it ever be necessary, which will be one of the primary roles of the commercial crew vehicles as they serve as “lifeboats” during their crew’s stay at the ISS.

Instead, crewed vehicles will attach to the ISS via a process of docking, whereby the visiting spacecraft flies itself all the way into its docking port and attaches via a capture ring striking a corresponding attachment mechanism.

Bottom line: NASA astronauts Barry Wilmore and Terry Virts aboard the International Space Station completed the first of three spacewalk on February 21, 2105. The second is scheduled for Wednesday, February 25 and the third for Sunday, March 1. The astronauts are securing cables to prepare the orbiting laboratory for future arrivals by U.S. commercial crew.
