25 Ice Mummies: The Ice Maiden

Follows archeologist Natalya Polosmok as she journeys to the Altay Mountains in southern Siberia to search for traces of an ancient people known as the Pazyryk. * Polosmok and her team discover and unearth a wooden tomb surrounded by the frozen remains of six horses, uncovering a 2,400-year-old woman dubbed the Siberian Ice Maiden. * The Ice Maiden is buried alone, lying as if asleep, in a wood coffin with a headdress and a mirror. An afterlife meal, a yak horn vessel and a wooden table are also found outside the coffin. Archeologists record the Ice Maiden's height, and discover a hole in her skull and peat packed in her body. *They use radiocarbon dating, tree-ring chronology and biological testing to determine the age of the remains and time of death. *The body is excavated and taken to Moscow for preservation and facial reconstruction. Another mummy, and other skeletons, are discovered elsewhere. *The program concludes by raising the question of who has rights to the ancient graves.

Air Date: 1997-01-30

26 Ice Mummies: A Life in Ice

In this second part of the Ice Mummies trilogy, attention turns to Ötzi, the Neolithic man plucked with an ice pick and some not inconsiderable brute force from an Alpine glacier. Once again, as with the Ice Maiden, an impressive set of relationships are on display in the vicinity of the leathery character and his bedraggled belongings. By far the most important man in Ötzi's life is Konrad Spindler, whose chance identification of the age of the mummy upon its discovery catapulted him to stardom and a life of analysis and scientific monitoring. Spindler is fiercely defensive of Ötzi, like Frankenstein and his monster, although the relationship is much less emotional than Natalia and her Ice Maiden. A bewildering array of more minor characters emerge during the course of the film, my particular favourite being a yodeling mountain dweller, included as a representation of how Ötzi has effected the local population. All varieties of archaeological life appear in this film, from Professors zur Nedden and Seidler, whose double act hints at the Muppets Stadtler and Waldorf, to an extra from This is Spinal Tap, Hanspeter Schrattenthaler, whose bare chest and rock star poses suggest he dearly wishes his copper axe were a guitar. Also worthy of mention is the lovable Harm Paulsen, who lives and works in a reconstruction of a Neolithic village and whose lilting Danish tones express some of the more human elements of the sad demise of Ötzi, such as the family he may have left behind, providing a stark contrast to the strictly 'scientific' views of Spindler.

The film traces the frozen bodies of children uncovered by archaeologists in South America, and follows an archaeological expedition to a high-altitude sacred site in search of ritual remains and another body. How did they come to be there? Why did they go to their deaths willingly? What was the religious framework that dictated their sacrifice to fierce gods?

43 What Sank the Kursk?

In August 2000, the Russian submarine, the Kursk, sank with the loss of 118 lives. It was a tragedy which shocked the world. But to many the tragedy remains incomprehensible, for the Kursk had been built to be unsinkable. How could this submarine have foundered? For a week after the tragedy the world watched in horror, as divers struggled to reach the crew trapped inside the Kursk. But the rescue efforts were in vain - all the sailors on board had perished. One overriding question dominated the aftermath of the disaster: what had caused the submarine to sink? As theories and counter-theories have multiplied, this mystery has been mired in confusion and acrimony. The Russians eventually claimed an American spy submarine had collided with the Kursk, causing her to sink - a claim the Americans flatly deny. But the Russian suspicions were based on logic. During the naval exercises there had indeed been two American submarines out in the Barents Sea, spying on the Russian weaponry and tactics. There is also a long history of collisions between US and Russian submarines in the Barents Sea. And above all, the Russians believed they had found overwhelming evidence showing the Kursk sank as a result of a collision with an American submarine. Satellite photographs and underwater footage all seemed to point to the Russian suspicions being correct. However, new scientific evidence suggests that the Russians were wrong. With access to the very latest scientific research, Horizon tells the story of the alternative theory that shows that it probably wasn't a collision, and may point to the true cause of the tragedy. The disaster left a series of geophysical fingerprints. Through a detailed forensic detective story, seismologists have now been able to establish that the Kursk sank because of an explosion, not a collision. But what had exploded? Horizon follows torpedo designers and chemists as they try to track down the precise cause of the explosion. The scientists' investigations take them back to a little-known submarine disaster that occurred almost fifty years ago: not in Russia, but in Britain. And as the scientists uncover the truth about what happened all those years ago, they may also solve the mystery of what really sank the Kursk. The most plausible cause is a leak of hydrogen peroxide, known as HTP, used in the Kursk torpedoes' fuel system. A chemical reaction between HTP and the metal torpedo case could cause a chain of explosions with a seismic trace similar to that observed on the day of the disaster. Update 7 May 2002 Since this programme was first shown, Russian officials have admitted they placed "unfounded trust" in torpedoes powered by HTP. They have now taken this type of torpedo out of service.

47 Pandemic: A Horizon Guide

In the wake of the swine flu outbreak, virologist Dr Mike Leahy goesw back over 50 years of BBC archives to explore the history of pandemics: waves of infectious diseases caused by bacteria, viruses or parasites. Inspired primarily by the Horizon back catalogue, he works his way through the diseases that have been tackled head-on through the 20th Century: polio, malaria, smallpox, AIDS, and up to the present day with SARS and the H5N1 bird-flu virus. Each pandemic episode tells us something about the world and our place within it. In his trip through the ages and the archives, Dr Leahy charts science's ongoing battle with nature and questions which one is winning. He makes a reasonable fist of the exercise, but is somewhat up against it as his source material can be patchy - first triumphant about man's successes and then defeatist when the previous triumph didn't work out quite as planned, etc.

48 Mars: A Horizon Guide

The intriguing possibility of life on Mars has fuelled man's quest to visit the Red Planet. Drawing on 45 years of Horizon archive, space expert Dr Kevin Fong presents a documentary on Earth's near neighbour. Man's extraordinary attempts to reach Mars have pushed technological boundaries past their limit and raised the tantalising prospect of establishing human colonies beyond our own planet. While the moon lies 240,000 miles away, Mars is at a distance of 50 million miles. Reaching the moon takes three days, but to land on Mars would take nearly eight months, and only two thirds of the missions to Mars have made it. The BBC has been there to analyse the highs and lows - including the ill-fated British attempt, the Beagle. Horizon has explored how scientists believe the only way to truly understand Mars is to send people there. If and when we do, it will be the most challenging trip humanity has ever undertaken.

49 How Many People Can Live on Planet Earth?

In a Horizon special, naturalist Sir David Attenborough investigates whether the world is heading for a population crisis. In his lengthy career, Sir David has watched the human population more than double from 2.5 billion in 1950 to nearly seven billion. He reflects on the profound effects of this rapid growth, both on humans and the environment. While much of the projected growth in human population is likely to come from the developing world, it is the lifestyle enjoyed by many in the West that has the most impact on the planet. Some experts claim that in the UK consumers use as much as two and a half times their fair share of Earth's resources. Sir David examines whether it is the duty of individuals to commit not only to smaller families, but to change the way they live for the sake of humanity and planet Earth.

50 Lost Horizons: The Big Bang

Professor Jim Al Khalili delves into over 50 years of the BBC science archive to tell the story behind the emergence of one of the greatest theories of modern science, the Big Bang. The remarkable idea that our universe simply began from nothing has not always been accepted with the conviction it is today and, from fiercely disputed leftfield beginnings, took the best part of the 20th century to emerge as the triumphant explanation of how the universe began. Using curious horn-shaped antennas, U-2 spy planes, satellites and particle accelerators, scientists have slowly pieced together the cosmological jigsaw, and this documentary charts the overwhelming evidence for a universe created by a Big Bang.

52 Diet: A Horizon Guide

Dr Susan Jebb takes a look through nearly fifty years of amazing BBC archive of mankind's relationship with what we eat, charting the shift from the malnutrition of the past to today's obesity epidemic. This is the story of our attempt to control nature through the wholesale industrialisation of food production in our search for enough to eat, and the consequences of that massive shift in our diet on the shape of our bodies, and the diseases that kill us. From the BBC's original eccentric scientist Magnus Pyke comparing the virtues of artificial additives to a Beethoven sonata, to the tragic side effects of diet pills, Horizon and the BBC have covered it all. On her journey through the decades, Dr Jebb explores how scientists have played a crucial role both in transforming the way our food is produced, but also in attempting to understand the biological mechanisms that determine why it is that some of us have become so large.

58 The Horizon Guide: Moon

Professor Brian Cox takes a look through nearly 50 years of BBC archive at the story of man's relationship with the Moon. From the BBC's space fanatic James Burke testing out the latest NASA equipment to 1960s interviews about the bacon-flavoured crystals that astronauts can survive on in space, to the iconic images of man's first steps on the Moon and the dramatic story of Apollo 13, Horizon and the BBC have covered it all. But since President Kennedy's goal of landing a man on the Moon before the end of the 1960s was reached, no one has succeeded in reigniting the public's enthusiasm for space travel and lunar voyages. Why? On his journey through the ages, Professor Cox explores the role that international competition played in getting man to the Moon and asks if, with America no longer the world's only superpower, we are at the dawn of a bright new space age.
