Aircraft-mounted cameras capture stunning views of polar regions

NASA is in the fifth year of its mission to survey the Arctic and Antarctic. Its cockpit cameras have gathered some spectacular footage…

NASA IS CURRENTLY undertaking the largest-ever airborne survey of the planet’s polar regions — known as Operation IceBridge. The US space agency’s P-3B aircraft have been tasked with collecting radar, laser altimetry and other data on the changing ice sheets of the Arctic and Antarctic circles.

The cockpit- and rear-mounted on-board cameras have also captured stunning vistas of some of the most remote regions on the globe: the sequence below shows highlights from the programme’s springtime flights over Greenland and the Arctic Ocean.

Each area is surveyed yearly using an array of instrumentation, and its planned the data collected will be used to produce what NASA describe as an “unprecedented three-dimensional view of Arctic and Antarctic ice sheets, ice shelves and sea ice”. According to the agency’s mission statement:

NASA’s Operation IceBridge images Earth’s polar ice in unprecedented detail to better understand processes that connect the polar regions with the global climate system.

In addition, IceBridge collects critical data used to predict the response of earth’s polar ice to climate change and resulting sea-level rise. IceBridge also helps bridge the gap in polar observations between NASA’s ICESat satellite missions.

The Greenland flights are conducted in March-May of each year, with the surveys of Antarctica taking place in in October-November. Other smaller airborne surveys also take place around the world.

    There is no possibility of Irish unity while sinn fein and the DUP are the main voices in northern politics . Two bitter, sectarian sides of the same coin, they need each other, feed off each other. But while either or both of them are on the pitch, nobody can win the game.

    A border poll is pointless as long as the large number of unionists who identify as British in the north are ignored or conveniently not part of such a process. They won’t go quietly and will not shy from fighting for what they hold close to their hearts. Like most Republicans I want a United Ireland….. but not at any cost

    @Marc Power: no one is advocating excluding or ignoring unionism, you’re confusing their unwillingness to engage in any form of discussion as them being ignored. But the Unionist veto is gone forever.

    @Marc Power: a border poll is pointless if
    1/ unionism is ignored
    2/ they won’t go quietly and will fight
    3/ you want unification but not at any price, ie the costs of above.
    You are precisely saying that a democratic poll is pointless because of those factors.

    I will vote no. It will cost us at least €10 billion which of course will but an end to Limerick to Cork motorway plus other projects. We would also have to put up with the bigotry of DUP and Sinn Fein. The only people who vote yes will be the shiners and some FF’ s

    Answer: NI decided they want a border poll. If they vote yes. ROI decide if we want them.

    Remainder of U.K. and ROI should not interfere till NI figure out what the want.

    It can’t be “Eff the unionists, because they lost”. That’s not how you treat somebody just because you disagree with their opinion. You’d have to do things like provide for schools where Irish is indeed an optional subject. And that’d just be the tip of the iceberg.

    Reunification is supposedly the only goal of nationalism, so if you can achieve that, any other olive branches you can offer to unionists should be on the table.

    The only thing worse than a sore loser is a sore winner. If nationalists win, people need to be prepared to be gracious winners. That’s all.

The majority of the population of Ireland wanted independence in 1919/1920, but hey the brits and the unionists didn’t agree hence we are where we are today. Sauce for the goose then, but not acceptable now according to your stance

    The only people who would have a vote are the people of northern Ireland. 90 % of the unionist population would vote no about 30% of the Catholic population would vote no. Can’t see it going thru. The people in the south can’t vote. As the population of GB can’t vote.

    It’s SF making political gain while this government staggers along drunk on this own PR spin. While Leo is busy dancing a tango around the fuzz. Micheál has gone virtual to impress. A welcome distraction on capitol hill. Even St Paddy himself would be applauded how community divides have being ripped open in America. All in the interest of one man. Who not only lost an election but also lost a coup attempt. Still leads a political party and holds court in this Florida palace. What good are virtual shamrocks when democracy is under attack.

    Should voters on both sides of the border agree ………….

    If we are a national community we must have sensitivity to all shades of Irishness … even the Ulster Scot who has resided on this island for centuries ..

    A majority or even a two thirds majority for anything does not define agree …..
    there is enormous need for agreement and that takes patience and time and understanding …there is no need for a vote ever …… just let it happen
    Any vote will simply drive us apart

    Cost issues would evaporate over time, because the social divide issues would. Reunification is a one way door, and sooner or later, most unionists would see it was a lost cause.
