Dc Icebridge Dryden B
The IceBridge mission , a six - yearNASAcampaign , is the big airborne survey of Earth ’s polar ice rink ever flown . It will yield never - before - seen 3 - five hundred image of Arctic and Antarctic frappe . The flights provide a annual , multi - perspective looking at at the behaviour of the quickly changing feature of the Greenland and Antarctic Ice Sheets and the glaciers that run from them into the ocean .
On Oct. 17 , the IceBridge DC-8 , parked outside the hanger at NASA ’s Dryden Flight Research Center in Edwards , Calif. , is groom for an instrument test flight .
Dc Icebridge Santiago B
The DC-8 flew to Santiago , Chile , on Oct. 21 , where it stayed overnight before heading to Punta Arenas , Chile – base for the 2010 Antarctic IceBridge mission .
Weddell Sea Radar B
The first trajectory of the IceBridge mission was flown on Oct. 27 . The researchers fly over the Weddell Sea , travel along a itinerary give by researchers from the year before . The satellite image shows differing ice thickness in the area .
Dc Icebridge B
Five days of forged weather delayed the first flight but finally everything cleared up and the team was capable to head out . This image testify a window scene of the Weddell Sea from the window of the mission ’s DC-8 .
Icebridge South Pole Flight
This map details the trajectory paths that researchers took during the the 2009 and 2010 IceBridge missions over the South Pole . The more late South Pole flight was undertaken Nov. 4 and is shown on the mathematical function in Orange River .
Icebridge South Pole Station
The Amundsen - Scott South Pole Station was easily visible during the Nov. 4 flight . By flying over the station , the researcher were able to use the GPS data that is being roll up there for their flight computations .
Runway Topography Icebridge
On Nov. 7 , while hold off for a replacement airplane part , Kyle Krabill , an locomotive engineer at NASA ’s Wallops Flight Facility made this topographic mathematical function of the runway the commission ’s DC-8 used . This type of map is called a " car survey " because it involves a three - hour journey criss - crossing the sidewalk at a maximum fastness of 5 miles per hour ( 8 kilometers per hour ) . An elevation single-valued function like this is vital for calibrating IceBridge ’s airborne instruments .
Icebridge Crew Takeoff
On Nov. 10 , the sheet had its new part and the research worker made another flight of the same South Pole spark from Nov. 4 . This image shows the DC-8 work party cook for takeoff .
Icebridge Timezone Map
During their flight around the South Pole , the DC-8 and all of its passenger will flew through enough time zones to go through Wednesday and Thursday . Here , a buffer shows a researcher how narrow the south-polar time zones are .
Icebridge Lvis Engineer
Shane Wake and Bryan Blair LVIS technologist and chief investigator at NASA ’s Goddard Spaceflight Center in Maryland - take a spirit at the LVIS legal document read - out in their place near the rear of the DC-8 . The LVIS ( Land , Vegetation and Ice Sensor ) takes measurements of surface meridian . A optical maser heart rate is air from the instrument and reflected back from the surface where the return pulse is recorded . Using those readings , scientists can direct the height of the ice below .
