As our expertise in space technology increases, there have been spin-offs in many areas: particularly in communications. This episode examines the profit-making satellite telecommunications industry and emerging techniques designed to increase the rates of data transmission from distant space probes
What if we could travel not just through space, but through time itself? If you could travel through time, would you change the past or the future? What if you found it couldn’t be changed? What price does the time traveller — and the people they are closest to — pay? This is a journey from H. G. Wells’ The Time Machine through ideas like The Grandfather Paradox and The Butterfly Effect to the professional time traveller that is the ever popular Doctor Who. Steven Moffat, David Tennant, Karen Gillan, and Neil Gaiman offer a unique perspective on the Doctor. Edward James Olmos reveals the hidden meaning of the language he created for the vision of the future that is Blade Runner. Bob Gale and Christopher Lloyd take us behind the scenes of Back to the Future, while Ed Solomon describes the joy of solving a time travel conundrum for Bill & Ted’s Excellent Adventure. But what would be the physical and emotional cost to the time traveller? Audrey Niffenegger explains what inspired her novel The Time Traveller’s Wife. And what if someone from the future tried to travel back in time to warn us? Would we believe them? From the apocalyptic tones of 12 Monkeys to the drama of Quantum Leap and the comedy of Groundhog Day, time travel is a subject that has been irresistible to the creators of every type of science fiction.
In 1976, the dream of supersonic commercial flight became a java: Concorde transported its first passengers. In the United States, Concorde awaits a new challenge: the competent service refuses to grant permission to land in New York. Over time, the White Bird becomes an aircraft of celebrities and important people. Three years after the tragic accident in 2000, Concorde was withdrawn from the service. Today NASA engineers in Ohio and Boom Supersonic experts in Denver reveal our latest research on supersonic flights of the future inspired by Concorde.
Two air catastrophes within five months of each other, both involving the same plane: the Boeing 737 MAX. How could these brand-new passenger jets, built by one of aviation's most trusted companies, just fall out of the sky? Now, through newly uncovered records, plus interviews with experts who investigated the crashes, we reveal why this seemingly reliable aircraft was headed toward disaster from the very beginning, and list the series of miscalculations, mistakes, and fraudulent maneuvers that sent 346 people to their deaths in 2018 and 2019.
