In this episode we talk about extra-vehicular activities, also known as spacewalking, with former astronaut Tom Jones. In the episode we cover the underwater training in the Neutral Buoyancy Lab, we talk about the preparation of the space walk in the shuttle, and of course we discuss the spacewalking itself. In particular, we talk about Tom’s participation in the STS-98 spacewalks that installed the Destiny lab onto the ISS.
Note: I forgot in the episode to thank some listeners for the questions they contributed: Daniel Hölbling, Andrew Moylan, Henning Krause, Mathias Menzer, Ekki Beyer-Christoph, Jake Brownson, Clive van Hilten, and somebody called Tim. Sorry for that.
This episode covers the moon, and in particular, its creation. We talk to the two scientists who came up with the theory of the moon’s creation that is still prevalent today: Don Davis and Bill Hartmann In the episode we discuss in detail their theory that the moon has been created by an impact event into earth, as well as some of the history of this theory. We also discuss other space related topics such as water on the moon, human vs. robotic space flight, and flights to Mars.
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.
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.
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 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).
This episode is a conversation with ESA astronaut Paolo Nespoli about the construction of and life on the ISS. As part of the STS-120 shuttle mission, Paolo was involved in installing the Harmony Module onto ISS. Later he served as a flight engineer on board ISS, as part of Expeditions 26 and 27. In the episode we talk about his two missions and compare the experiences on the Shuttle, the ISS and the Soyuz.
In dieser Episode unterhalte ich mich mit Denis Regenbrecht vom DLR Raumfahrtmanagement über die europäische Ariane Rakete (inbesondere über die Ariane 5). Wir sprechen über die Historie (Ariane 1 bis 5), die Struktur und die wichtigen Baugruppen der Ariane 5 sowie den Ablauf einer typischen Mission.
