This is the first of two episodes recorded at the Planetary Science Institute in Tucson, Arizona. This episode has two interviews. The first one, with Mark Sykes, the director of PSI, is about the PSI and planetary science in general. The second interview is with Beatrice Mueller about her research area, comets.

This epsiode covers my visit at the Large Binocular Telescope near Tucson, Arizona. The episode is mostly a conversation with the telescope's director, Richard Green. We talk about optical astronomy in general and the LBT in particular. I also talk to a scientist who is currently observing at the telescope as well as a telescope operator.

This episode is a conversation with JPL's Anita Sengupta about Curiosity's landing on Mars. We first discuss the landing process itself and then focus on various aspects of the landing, in particular, the parachute. Next we discuss the development and test of that parachute. We conclude the episode with a general discussion about Mars Science Lab, Curiosity and space flight in general.

This is the long-awaited episode about the Lockheed U-2 Dragon Lady reconnaissance airplaine, the highest-flying jet-powered airplane currently in use. Our guest in the episode is Carl LaRue who has been flying the U-2C and the U-2R in the 60s and 70s. In the episode we discuss the airplane itself, the challenge of flying it, as well as a number of anecdotes surrounding the Dragon Lady.

In this episode we talk to Ryan Murphy of ETH Zuerich about Game Theory. We introduce the topic in general, discuss a number of important games and also address their applicability for various other sciences, including biology, politics and economics.

In this episode we talk to Rainer Kresken of ESA ESOC Darmstadt about orbital mechanics and space flight dynamics. We have obviously addressed this topic in earlier episodes, this episode really diggs down deeper, and helped me understand the concepts and the challenges much better.

This episode wraps up our recent coverage on particle physics by discussing in some detail the recent discovery of a Higgs particle. Our guest in this episode is Kerstin Borras who heads up the CMS group at DESY. We recap the role of the Higgs very briefly, look in some detail at the two detectors CMS and ATLAS, discuss the importance of the famous five sigma and look at the process by which such a discovery is confirmed and (re-)checked.

In this 100th episode of omega tau we talk to Dr. Stephen B. Johnson about system health management, a set of techniques and processes used to improve system dependability. The episode is based on a book Stephen co-edited, and as a consequence of Stephen's background, we use aerospace examples in this episode. We discuss the fundamental concepts such as functions, states and the state vector, failures and faults. We then discuss the influence of complexity on failures, as well as human involvement. We discuss means to prevent failures such as fault isolation, redundancy and model adjustment. We conclude the three-hour conversation by looking at the future of systems engineering and system health management with a particular focus on formal methods.

This episode is a conversation about airborne wind energy. In particular, we talk to Roland Schmehl who leads a team of researchers and engineers at TU Delft who develop the Kitepower system. In this system, kites are automatically flown in a pumping pattern to extract energy from wind as an alternative to classical ground-based wind turbines. In the conversation we cover the benefits of airborne wind energy in general and of kites in particular and we cover in some detail how the Delft system works technically.

This is the long-awaited follow-up to the first Apollo episode, once again with W. David Woods, author of How Apollo Flew to the Moon. In this episode we cover that part that we omitted in the first episode: the time on the moon. We talk about life support, the various scientific instruments and experiments as well as the technology and use of the lunar rover (about which David is actually writing another book).
