NOVA
Lethal Seas

 

Marine scientists across the world are hunting for clues to one of the greatest environmental catastrophes facing our planet today: ocean acidification. For years we’ve known the ocean absorbs about a quarter of the carbon dioxide in Earth’s atmosphere. But as carbon emissions continue to rise, seawater chemistry is changing, and the ocean’s acidity is increasing. As a result, the skeletons and shells of marine creatures that form the foundation of the web of life are dissolving. Follow scientists who are seeking solutions and making breakthrough discoveries, including a unique coral garden in Papua New Guinea that offers a glimpse of what the seas could be like in a half-century.

Mars was once a blue water world studded with active volcanoes. But when its magnetic field and protective atmosphere faded, it became the frozen desert planet we know today. With so many necessary elements in place, did life ever form on Mars?

 

 

 

The Farthest – Voyager in Space

 

With participation from more than 20 of the original and current mission scientists, engineers and team members, this program tells captivating tales of one of humanity’s greatest achievements in space exploration. From supermarket aluminum foil added at the last minute to protect the craft from radiation, to the near disasters at launch, to the emergency maneuvers to fix a crucial frozen instrument platform, viewers get a sense of how difficult – and rewarding – space exploration can be. NASA’s epic Voyager missions, launched in 1977, revolutionized our understanding of Jupiter, Saturn, Uranus, Neptune and their dazzling moons and rings. In 2012, Voyager 1 left our solar system and ushered humanity into the interstellar age.
