Big Picture Science for May 01, 2023 -Finding Endurance

Big Picture Science - Finding Endurance

(REPEAT)
In 1915, Endurance, the ship that took Ernest Shackleton to the Antarctic, was slowly crushed and sank. Shackleton, and the 28 men he brought with him, were camped on the ice near the ship, and watched helplessly as their transport went to a watery grave, two miles down.

But a recent expedition has found the Endurance, taking the world back to the last hurrah of the heroic age of polar expedition. How was it found, and what will be done with it?

Also, while feats of exploration inspire TV shows and magazine articles, do they have other functions in society? Is modern exploration more than just a nice thing to do?

We go to the bottom of the world on “Finding Endurance.”

Guests:

• Michael Smith – Author and journalist. His book: “Shackleton: By Endurance We Conquer”
• Christian Katlein – Sea ice physicist
• Tim Jarvis – Adventurer and environmental scientist

Electric Blue Clouds over Antarctica

NASA's AIM spacecraft has spotted electric-blue clouds forming over Antarctica.  These are noctilucent clouds (NLCs) and their apparition marks the beginning of the 2014-2015 season for southern NLCs.  By the second week of December, Antarctica could be blanketed in electric blue.

The Antarctic ozone hole reached its annual peak size on Sept. 11, according to scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA). The size of this year’s hole was 24.1 million square kilometers (9.3 million square miles) — an area roughly the size of North America.

A new study by researchers at NASA and the University of California, Irvine, finds a rapidly melting section of the West Antarctic Ice Sheet appears to be in irreversible decline, with nothing to stop the glaciers in this area from melting into the sea.

Big Picture Science for 08/29/11 - Into the Unknown

Big Picture Science - Into the Unknown

During the great age of exploration men risked their lives to set foot upon unknown lands, whether in the humid jungles of Peru or on the barren ice cap of the South Pole. We’ll hear those dramatic tales…

… but also where modern exploration is taking us. Could it be to the deepest, darkest part of the sea?

Or to space? Discover how to build a space suit that will let you move like an athlete on Mars. Also, why some say that the ultimate frontier requires no packing and no travel: voyages into the human brain.

Guests:

• Dava Newman – Professor of Aeronautics and Astronautics Engineering Systems, MIT
• David Eagleman – Neuroscientist, Baylor College of Medicine and author of Incognito: The Secret Lives of the Brain
• Mark Adams – Author of An Empire of Ice: Scott, Shackleton and the Heroic Age of Antarctic Science
• Edward Larson – Author of An Empire of Ice: Scott, Shackleton and the Heroic Age of Antarctic Science
• Liz Taylor – President, Deep Ocean Exploration and Research, Alameda, CA
