Fifty years ago, Stanley Kubrick and Arthur C. Clarke set out to make a new kind of sci-fi. How does their future look now that it’s the past?

Prepare for liftoff. In this episode we go deep into space: into the known unknowns we’ve explored, and the unknown unknowns that lie ahead.
Feet on the Ground, Eyes on the Stars: The True Story of a Real Rocket Man with G.A. “Jim” Ogle – User Defenders podcast : Inspiring Interviews with UX Superheroes.
G.A. “Jim” Ogle fell in love with airplanes at the early age of 8 years old. The circumstances that presented this initial passion were far from ideal.
He was recovering in a hospital bed following a 7-hour surgery to essentially re-attach his badly mangled right leg from a horrible school bus wreck. He awoke from the operation to see a model airplane hanging down from a wooden structure over his bed that was to be used as a traction device to slowly pull his left leg back into place. It was broken at the hip and rammed almost three inches into his lower torso.
His injuries would prevent him from being a pilot in the Air Force. But this reality would not deter him from being in the air with airplanes because 12 years later he became involved in space with missiles and rockets on his first job at Cape Canaveral, Florida in 1958. This was the beginning of his 51-year career of being associated with every manned moon mission and all 135 Space Shuttle missions. He finally got his layoff notice along with 8,000 other space workers following the final Shuttle mission, STS-135, in July 2011.
He likes to tell folks questioning his unusual longevity in this field that he was fortunate to be “in the right place at the right time and the right age.” He considers himself blessed for having had the opportunity to be a part of this truly exciting time in America’s beginnings in space.
Fun fact: Jim requires 10 lemons and multiple servings of tartar sauce with every seafood meal. The last lemon squeeze after the meal is used to clean his hands!
In partnership with aerospace engineers and the Nevada Museum of Art, Trevor Paglen will launch Orbital Reflector into low-earth orbit as the world’s first nonutilitarian satellite. This ephemeral artwork will have a life span of several weeks. Paglen aims to make an artistic and aesthetic statement while encouraging dialogue related to larger issues surrounding the interdisciplinary fields of science, engineering, politics, and space.

If we find, anywhere in the universe, one more instance of life besides what evolved on Earth, then we are bound to conclude that life is common throughout the vastness of this galaxy and the 200 billion other galaxies.
The discovery would change how we think about everything.
Most of the search for life beyond Earth, Porco explained, is the search for habitats.
They don’t have to look comfy, since we know that our own extremophile organisms can survive temperatures up to 250°F, total desiccation, and fiercely high radiation, high pressure, high acidity, high alkalinity, and high salinity.
In our own Solar System there are four promising candidate habitats—Mars, Europa (a moon of Jupiter), Titan (a moon of Saturn), and Enceladus (“en-SELL-ah-duss,” another moon of Saturn).
They are the best nearby candidates because they have or have had liquids, they have bio-usable energy (solar or chemical), they have existed long enough to sustain evolution, and they are accessible for gathering samples.
On Mars water once flowed copiously.
It still makes frost and ice, but present conditions on Mars are so hostile to life that most of the search there now is focussed on finding signs of life far in the past.
Europa, about the size of Earth’s Moon, has a salty ocean below an icy surface, but it is subject to intense radiation.
Photos from the Hubble Space Telescope revealed that occasional plumes of material are ejected through Europa’s ice, so future missions to Jupiter will attempt to fly by and analyze them for possible chemical signatures of life.
The two interesting moons of Saturn are Titan, somewhat larger and much denser than our Moon, and tiny Enceladus, one-seventh the diameter of our Moon.
Both have been closely studied by the Cassini Mission since
Titan’s hazy atmosphere is full of organic methane, and its surface has features like dunes and liquid-methane lakes “that look like the coast of Maine.”
But it is so cold, at 300°F below zero, that the chemical reactions needed for life may be too difficult.
Enceladus looks the most promising.
Cassini has sampled the plumes of material that keep geysering out of the south pole.
The material apparently comes from an interior water ocean about as salty as our ocean, and silica particles may indicate hydrothermal vents like ours.
“I hope you’re gettin excited now,” Porco told the audience, “because we were.”
The hydrothermal vents in Earth’s oceans are rich with life.
Enceladus has all the ingredients of a habitat for life—liquid water, organics, chemical energy, salts, and nitrogen-bearing compounds.
We need to look closer.
A future mission (arriving perhaps by the 2030’s) could orbit Enceladus and continually sample the plumes with instruments designed to detect signs of life such as complexity in the molecules and abundance patterns of carbon in amino acids that could indicate no biology, or Earth-like biology, or quite different biology.
You could even look for intact organisms.
Nearly all of the material in the plumes falls back to the surface.
Suppose you had a lander there.
“It’s always snowing at the south pole of Enceladus,” Porco said.
“Could it be snowing microbes?”
(A by-the-way from the Q&A:
Voyager, which was launched 40 years ago in 1977, led the way to the outer planets and moons of our Solar System, and five years ago, Porco pointed out, “It went beyond the magnetic bubble of the Sun and redefined us as an interstellar species.”)

For the last few years, WikiHouse Foundation have been developing open source technologies to digitise and democratise the way we make homes. In this talk, Alastair shares WikiHouse Foundation’s vision for a new kind of digital civic infrastructure, one they believe has the potential to transform the way we design, make and learn from the physical world around us.

Carlos Frenk, Eugenia Cheng, Jim Al-Khalili and Louisa Preston debate time and space.
Carlos Frenk, Eugenia Cheng, Jim Al-Khalili and Louisa Preston debate time and space with presenter Rana Mitter and an audience at Radio 3’s Free Thinking Festival at Sage Gateshead.
We can measure time passing but what actually is it? What do scientists mean when they suggest that time is an illusion. Can time exist in a black hole? Is everyone’s experience of time subjective? What is the connection between time and space? How does maths help us understand the universe?
Professor Carlos Frenk is founding Director of the Institute for Computational Cosmology at Durham University and the winner of the Gold Medal of the Royal Astronomical Society in 2014.
Dr Eugenia Cheng is Scientist in Residence at the School of the Art Institute of Chicago and an Honorary Fellow of the University of Sheffield. She is trilingual, a concert-level classical pianist and the author of Beyond Infinity: An Expedition To The Outer Limits Of The Mathematical Universe.
Jim Al-Khalili is Professor of Physics at the University of Surrey and presenter of BBC Radio 4’s The Life Scientific and TV documentaries. His books include Paradox: the Nine Greatest Enigmas in Science, Black Holes, Wormholes and Time Machines and Quantum: a Guide for the Perplexed.
Dr Louisa Preston is a UK Space Agency Aurora Research Fellow. An astrobiologist, planetary geologist and author, she is based at Birkbeck, University of London. Her first book is Goldilocks and the Water Bears: the Search for Life in the Universe.
What first attracted one of the world’s foremost astrophysicists to the night sky? Are we alone in the universe? And how can scientific thinking benefit us all?
