Perché le linee aeree non volano sopra al Polo Sud

Geek   13.12.21  

Le compagnie aeree sorvolano continuamente il Polo Nord per collegare l'Europa, il Nord America e l'Asia con rotte ortodromiche; tuttavia, seppure l'Antartide sia raggiungibile anche da voli commerciali, le compagnie aeree preferiscono rotte più lunghe per collegare gli aeroporti dell'emisfero australe pur di evitare il circolo polare antartico.
Half as Interesting spiega i motivi tecnici e logistici che sono alla base di questa decisione.

Sopravvivere all'inverno in Antartide

Geek   18.02.15  

Trascorrere l'inverno nella base permanente Amudsen-Scott al Polo Sud è una sfida per le decine di ricercatori isolati per mesi a 2.863 metri sul livello del mare, a una temperatura media di -49° C, in uno degli ambienti più inospitali e remoti della Terra.

The Amundsen-Scott South Pole Station is the southern-most of the three U.S. research stations down in Earth’s basement. It is located about a hundred meters from the pole itself. It houses around 150 people during the summer and 50 during the winter. The other stations are McMurdo Station, located on Ross Island, and Palmer Station, on Anvers Island. McMurdo is the most populous of the bunch, with 800 to 900 people residing there in the summer and nearly 150 during the winter. Winter on Antarctica’s Ross Island is slightly shorter than at the South Pole. This winter, planes will fly intermittently out of McMurdo, where winter begins on February 28, and the station’s summer crowd arrives on October 1.

The U.S. Antarctic Program doesn't fly over Antarctica during the winter, even between bases, because temperatures get below -50 degrees Fahrenheit, the point at which gasoline freezes. In the depths of winter, around the beginning of July, temperatures can drop below -100 degrees Farenheit. Compounding the cold is the altitude--the South Pole station is nearly 10,000 feet above sea level. In such conditions, even breathing can be painful. Many who attempt to join the 300 Club--a group that endures a 300-degree temperature change by heating themselves in a 200-degree sauna and then streaking naked to the pole and back in sub-negative-100-degree weather--will often wear a scarf, if nothing else.

Le fotografie perdute del capitano Scott

Herbert Ponting fotografa il Terra Nova

Un libro ripercorre la tragica spedizione di Robert Falcon Scott al Polo Sud e la sua leggendaria competizione con Roald Amundsen, con fotografie rimaste inedite per un secolo.

In 1910, Captain Robert Falcon Scott and a small crew of men embarked on the infamous Terra Nova Expedition to the South Pole, only to arrive there on January 17, 1912, and discover that a Norwegian expedition had beaten them to the feat. To add tragedy to letdown, the crew never made it home -- they perished on the way back in the grip of starvation, exhaustion, and extreme cold. Though it was known that Captain Scott documented the ill-fated expedition in a wealth of photos, the location of most of them remained a mystery for nearly a century.
