This episode is a mix between computer architecture, programming and (historic) space flight. We cover the ins and outs of the Apollo Guidance Computer. Our guest ist Frank O’Brien, who wrote an incredibly detailed book about this machine. In the episode we cover the hardware architecture, the instruction set, the various layers (native, executive and interpreter) as well as some mission programs.
This episode is a conversation with Ruud Hoogeveen from the Netherlands Institute for Space Research about satellite-based Earth observation, and primarily about measuring the concentration of gases such as CO2 or Ozone from space. We talk about the effects of these gases on the atmosphere, how the sensors work in principle, and about the history and evolution of the sensors over the various missions. We conclude with a look on detecting and measuring aerosols and at the future challenges and current research for satellite-based earth observation.
In this episode we talk about mission control for the Space Shuttle. Our guest is Dan Adamo, a former flight dynamics officer (FDO) in the Mission Control Center. We cover the organization of mission control, the various roles, qualification and training, the specific tasks of the FDO as well as a little bit of history. Dan also relates many interesting episodes from his time “in the trench”.
This is the last episode in 2014. Nora and Markus wish you Merry Christmas, a few quiet days between the years and a good start into 2015. Stay tuned, there’s a lot of good stuff coming on this station :-)
In this episode we talk with Jochen Liske from the European Southern Observatory about the E-ELT Telescope for which construction is about to start. We discuss the engineering challenges of building a 40m mirror and the associated telescope, as well as the science that is planned to be addressed with the E-ELT once it is finished. We also discuss a number of issues around optical astronomy in general that were not covered in our episode about the LBT.
Joe Liske is also the host of both the HUBBLEcast and the ESOCast, two video podcasts about astronomy you may want to check out.
This is the second of two episodes on the the Space Shuttle’s systems and operations. We talk to Davide Sivolella, an aerospace engineer who has written a quite technical book on the shuttle. In this episode we talk about some of the shuttle’s operations, including launch, landing and proximity operations in space.
This is the first of two episodes on the the Space Shuttle’s systems and operations. We talk to Davide Sivolella, an aerospace engineer who has written a quite technical book on the shuttle. In this episode we talk about some of the shuttle’s systems, including the structure, the engines, the boosters and the thermal protection system.
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.
