On today’s episode Dr. Ralf Gellert, principal investigator of the Alpha Particle X-Ray Spectromer, or APXS, one of the primary instruments on the Mars Curiosity rover, joins Justin Trottier at The Star Spot to discuss how his instrument is currently assisting in the search for signs of Martian habitability. Dr. Gellert compares Curiosity to its predecessors, especially the Mars Exploration Rovers Spirit and Opportunity on which he continues to work. He describes how Curiosity's ten instruments together contribute to the mission goals, ponders whether we'll ever know for sure if Mars was, or was not, habitable, and shares his hope that the next step in Martian exploration would be a sample return mission. Gellert gives a feel for the complexity and scale of planetary exploration missions, describing how government, research institutions and private industry collaborate, and how Curiosity has become and international project.
In Current in Space we report on the discovery of super-luminous supernovae out at edge of the observable universe, and provide an update on Voyager 1 and its mission to a different edge - that of our own solar system.

Appropriate to Episode #13, given the superstitious associations of that particular number, our guest today, Guy P. Harrison, is a debunker of superstitions and paranormal beliefs of all stripes. He joins Justin Trottier at The Star Spot to discuss his newest book 50 Popular Beliefs That People Think Are True. After an introduction to skepticism, why it's vitally important and how it differs from simply cynicism or denial, the two focus down on a variety of exciting specific beliefs: ancient aliens, modern UFOs, abductions, astrology, and the moon landing hoax. Harrison explains what convinced him to give up his belief that ancient aliens visited the Earth. He explains what we can learn about psychology and culture by looking seriously at alien abduction experiences. He confronts the most effective arguments of the moon landing hoax community and finally explains why we shouldn't take our newspaper horoscopes too seriously.
In Current in Space we comment on discussions from the 100 Year Starship initiative which seeks to prepare for interstellar travel within a century. At a recent symposium everything from new possibilities for warp drives to a debate about whether religion should accompany humanity was on the table. Finally, we provide an update on the status of the B612 Foundation's Sentinel mission, a sun-orbiting telescope that will increase our ability to track dangerous asteroids on potential collision courses with Earth.

Our guest today is Patrick Hall who joins Justin Trottier at The Star Spot to discuss one of the most energetic, myserious and ancient of phenomana in our universe: quasars. Hall shares his insights into the role quasars played in the evolution of the cosmos and galaxy formation, the mechanisms and physics of their behaviour, and the rare occurence of double quasars. He also describes the eventual fate of our Milky Way Galaxy to merge with Andromeda and produce quasars of our own. Finally, they focus on the Sloan Digital Sky Survey and explore the tremendous opportunities afforded researchers by the growing scale and scope of large sky surveys.
In Current in Space we introduce a cryptic new start-up company Uwingu seeking to fundraising and raise public engagement in space exploration, comment on the enduring fascination with the concept of a space elevator, and pay tribute to one of the greatest explorers of our time - Neil Armstrong.

Our guest today is Julian Barbour who joins Justin Trottier at The Star Spot to share his unique insights into the elusive mystery of time. He explains how new perspectives and research he is leading on time - which take seriously the puzzling implications of the Many World interpretation of quantum mechanics - may herald a new revolution in physics. The two explore the paradoxes of simultaneity and duration, asking how we know a second today is the same as a second a billion years ago. They then discuss Barbour's own personal paradox, in which his belief that time is illusory exists alongside his fascination with human history. In his own eccentric, provocative and illuminating style, Barbour finally takes listeners on a tour of platonia, a new concept in which existence is turned into a series of nows - or time capsules - and time is intricately connected to every activity in the universe.
Barbour is a theoretical physicist. Uniquely, he contributes to various fields without holding an academic position. He works part time as a translator and lives on a farm north of Oxford village. He’s been a visiting professor at the University of Oxford since 2008.

Our guest today is Professor Sarah Symons who joins Justin Trottier at The Star Spot to enlighten us about ancient Egyptian sophisticated conceptions of the night sky. The conversation ranges from understanding the intimate interplay between the supernatural and the scientific, to the practical uses of the stars for such purposes as predicting the flood of the Nile, and to the role of special classes of stars in ancient Egyptian myth and ritual.
Dr. Symons shares her enthusiasm in detailing how the night sky was at the centre of Egyptian religion. Pharoahs sought to transform themself into celestial beings, while the very body of one goddess formed the foundation of the Egyptian conception of celestial regularities. To close their conversation, the two reflect on why ancient Egypt continues to catalyze so much wild and crazy pseudoscentific and pseudoastronomical theorizing.
In Current in Space we discuss the illuminating findings from the nineth collection of UFO files recently turned over by the British government, then prepare for the August 6th landing of the Mars Science Laboratory Curiosity Rover by exploring the many unique attributes of this most exciting mission to the red planet.
