Feature Guest: Peter Visscher
The return of humans to the moon is well over a decade away. But one key step, the development of unmanned lunar rovers that could be scaled up for human exploration, is well underway. Today on the star spot i’m joined by Peter Visccher, an engineer working to design just this future.
Ontario Drive and Gear Ltd, popularly known as Argo after their trademark all-terrain amphibious vehicles, was founded in 1962. The company’s vehicles are well known in recreational, industrial and search and rescue functions. More recently under contract to the Canadian Space Agency and in coordination with NASA, they’re moving into lunar rover design. To bring us up to speed on the return to the moon agenda and where lunar rovers fit into the plans, I’m joined here at the Star Spot by Peter Visscher, profession engineer and program manager of space and robotics at Ontario Drive and Gear.
Current in Space
In today’s Current in Space, Benjamin waxes poetic with an ode to death... of the largest known star in our universe. Then Anuj picks up the narrative by sharing what astronomers are now able to learn from the ashes of long gone planets circling deceased stars.

Feature Guest: Jill Tarter
The Search for Extraterrestrial Intelligence. No other space-related program so effectively stirs our emotions, symbolizes our sense of hope and optimism for the future, or provokes philosophical debates about the meaning of our life and our place in the universe. Today Justin Trottier talks with Dr. Jill Tarter, a key player and icon of SETI, the Search for Extraterrestrial Intelligence. The Star Spot was privileged to be invited to interview the real life inspiration behind the protagonist in the film Contact in front of a live audience at a special fall equinox event hosted by the educational charity the Centre for Inquiry.
Current in Space
In today’s Current in Space, Denise shows that weather isn’t a boring topic of conversation, provided you’re talking about cloud cover on an extrasolar planet. Then Anuj surprises us with new discoveries of early atmospheric oxygen that could push back the clock on important components in the the evolutionary tree. And finally Victoria talks of two-face pulsars, which can alternates between X-rays and radiowave emission in just a few weeks!

Feature Guest: Martin Laforest
Martin Laforest joins Justin Trottier at The Star Spot to discuss the fascinating, complex and bizarre world of the quantum. After describing the Institute for Quantum Computing and the uniqueness of its home, the University of Waterloo and the technological industrial hub of Waterloo, Ontario, the two explore quantum information, cryptography, and the often counter-intuitive theoretical underpinnings of these technological breakthroughs.
Justin then goes through his list of fanciful “science meets science fiction” topics, ranging from quantum teleportation and replication to what possible effect it would have on SETI (Search for Extraterrestrial Intelligence) if aliens have moved on to using quantum encoded signals in their communication.
Finally Laforest comments on how we can harness a topic like quantum computing - which has excited public interest but is inherently complicated - to drum up interest in science.
Current in Space
As a special treat, given that we missed our last regularly scheduled episode, we’ve included an expanded Current in Space segment featuring:

“When beggars die there are no comets seen. The heavens themselves blaze forth the death of princes.”
- William Shakespeare’s Julius Caesar, Act 2, Scene 2
Feature Guest: David Levy
As we are quickly learning, our solar system is anything but quiet. Today we celebrate the very dynamic and violent place that is our home and immediate neighborhood. In Current in Space we covers the stormy space weather that will greet us shortly when the sun’s magnetic field flips. Then we ask if supposedly dead comets can be resurrected to continue their adventurous and on rare occasions, disastrous, lives.
Finally David Levy joins Justin Trottier at The Star Spot .The giant of comet hunting, who discovered 22 comets, including Comet Shoemaker-Levy 9 which collided with Jupiter in 1994, explains why comets are part of our culture. Following a far ranging interview sprinkled with quotes from Shakespeare, comparisons to cats, and the famous Shoemaker-Levy 9 discovery story, Levy concludes with musings on the grim decline in amateur comet hunting but a hopeful future of comet discovery around extrasolar planets.
About David Levy
Despite the lack of formal training in astronomy or space sciences, David Levy would go on to become a comet hunting legend, discovering or co-discovering 22 comets and publishing 34 books, most on astronomical subjects. He is best known as the co-discover of Comet Shoemaker-Levy 9 which crashed into Jupiter in 1994.
A literature student, he received a PhD from the Hebrew University of Jerusalem in 2010 for his thesis “The sky in early modern english literature.” As I learned during our conversation he enjoys combining his love of comets with his passion for literature, especially Shakespeare, whom he is likely to quote when discussing the importance of comets to our culture.
In 1998 Levy also won a News and Documentary Emmy Award for the script of 3 minutes to impact, a documentary produced for the discovery channel.

Feature Guest: Anne-Marie Weijmans
Dark matter and galaxies turn out to live together as intimate partners. What role did dark matter play in the formation, characteristics and subsequent evolution of galaxies in our universe? And what do our studies of galaxies in turn teach us about the nature of dark matter haloes? To help answer those questions, Dr. Anne-Marie Weijmans joins Justin Trottier at the Star Spot.
The two touch on tantalizing and little known discoveries. Evidence of ancient dwarf galaxy mergers from the movement of stars in our galaxy. Dark matter in our own solar system. And the previously empty space between galaxies turns out to harbor dark matter haloes extending between galactic islands.
Current in Space
Victoria Duncan shares new data from the Mars Reconnaissance Orbiter focused on the Mars northern lowlands showing evidence of fossilized water channels and even an ancient river delta. Jessica Campbell on what we’re learning about how dark holes accrete mass and grow by studying gas around the Milky Way’s own supermassive black hole. And Denise Fong asks, Where are all the waves on Saturn’s larget moon, Titan?
About Anne-Marie Weijmans
Dr. Anne-Marie Weijmans is Fellow at the Dunlap Institute for Astronomy and Astrophysics at the University of Toronto. This summer 2013 she is working as lecturer at the school of physics and astronomy at the University of St. Andrews in Scotland. Her specialty is in galactic dark matter haloes.

Feature Guest: James Robert Brown
We talk a lot at The Star Spot about space, but what, exactly, is space, or time for that matter, and how is it we can know anything at all about our universe and its laws. Some have pronounced the death of philosophy at the hands of science. But are rumours of the discipline's death greatly exaggerated? Philosopher of science James Robert Brown joins Justin Trottier at The Star Spot to discuss the history and philosophy of astronomy.
After introducing the work of philosophy of science, Brown describes the pervasive nature of arguments over the basic nature of space and time, defends Platonism, speaks to the odd power of thought experiments, and provides an update from the frontlines in the Science Wars. Brown also assures us why we should not worry over new attempts to rehabilitate the reality of time. The passage of time is still an illusion after all!
Current in Space
Denise Fong and Jessica Campbell discuss new insight into space wind and why it should matter to you, plus what we're learning from the leftovers of supernovae 1987A in the Large Magellanic Cloud.
About James Robert Brown
James Robert Brown is philosopher of science and mathematics in the Department of Philosophy at the University of Toronto. He is the author of many excellent books including The Laboratory of the Mind: Thought experiments in the natural sciences, Smoke and mirrors: how science reflects reality, and Who Rules in Science: An opinionated guide to the wars. His diverse interests include scientific realism, platonism, foundations of physics and the relationship between science and politics, religion and commercialization.

Feature Guest: Christopher McKee
Astronomy and science popularizaer Carl Sagan famously declared “We are all starstuff.” He was referring to the discovery that much of the heavier elements in our body formed in the supernovas of dying stars. But after supernovas eject material out into the galaxy, how does that gas - and the rest of the interstellar medium - form into new stars, planets and ultimately us? To help answer that question Christopher McKee joins Justin Trottier at The Star Spot.
The two discuss McKee's contribution to our understanding of the interstellar medium, how the discovery of dark matter effected his model, and what role his work in two very different areas of astrophysics - quasars and the space between the stars - played in advancing his career.

Episode 30: Hacking the Future of Space Exploration, Featuring the International Space Apps Challenge
On the weekend of April 20, 2013, 9000 people from over 80 countries responded to NASA’s call to hack their way towards unique and innovative solutions to special space challenges. A huge array of projects were available, from designing a deployable greenhouse for Mars to building an app to help visualize the topography of the dark side of the moon, to more arts related projects like designing jewellery celebrating the unique properties of 55 Cancri E, a carbon-rich Super Earth planet.
To assist NASA provided scientists and other experts as consultants through live international hookups. The goal? To open up both space exploration and social need while empowering citizens around the world. The event was the international space apps challenge.
On today’s episode of The Star Spot we chat with Jonathan Moneta, an organizer with the Toronto contingent. Then, we speak with William Sellier, a member of the team Green Mars. Green Mars, which answered the challenge of designing the concept for a deployable greenhouse for a future mission to Mars, won one of the two Best in Hardware awards. Finally, we hear from 4 members of the Team known as Museum of Intergalactic Species (Jane Saputra, Charlotte Tang, Kris Nicolaoum, and Mario Dabrowski). Their challenge was to adopt a space-craft, that is to humanize the voyager mission by telling the story of the first human object to leave the solar system in an innovative and interactive way that connected it to people’s lives.
