The Earth is one ordinary planet among many orbiting one typical sun among many in an unremarkable galaxy, the Milky Way, one of countless galaxies in an ever-expanding universe.

Since the beginning of human civilisation, people have looked up at the night sky and wondered – are we alone? The science and technology of the 20th century have made it possible to try to address that question. So how is are we doing?

What have been the near-misses? How has the search evolved since then? What are the current prospects of detecting a signal?

Jill Tarter from @SETIInstitute has worked on a number of major scientific projects, most relating to the search for extraterrestrial life and the attempt to answer the question ”Are we alone in the universe.  The 1997 Hollywood film ‘Contact’ starring Jodi Foster was largely based on her work. 

As the former director of the SETI Institute, she explains when SETI research began, the technology used, how it is funded and the global collaborative international endeavour it has now become.

Episode 95 European Space Cooperation DeGaulle to ExoMars with Brian Harvey

By Leave a Comment

The latest book from author Brian Harvey @BrianHarveyAut1 is probably the first English-language analysis of the individuals, institutions, and early space projects that would eventually lead not just France but Europe to its status as a leader in designing, building, and operating complex space infrastructure. 

This is probably the first English-language analysis of the individuals, institutions, and early space projects that would eventually lead not just France but Europe to its status as a leader in designing, building, and operating complex space infrastructure.

In the first chapter, “Early Days”, the author refers to John F. Kennedy’s little-known but perhaps most powerful speech on 10 June 1963, Strategy for Peace. Here, it would have been interesting to see the author’s assessment of how space collaboration has cultivated peace on Earth.

In this episode, Brian talks about his motivation for writing this book and accessing the complex sources he needed to tell this story.

Episode 94 Seti – Techniques and Technology with Jill Tarter

By Leave a Comment

The systematic search for extraterrestrial intelligence could only begin once the technology was sufficiently mature. That happened in early 1960s. Until then SETI was firmly in the realm of science fiction. 

How has the SETI evolved over the last six decades and especially what can modern technology allow today that was not possible then?

Episode 93: Exploring the surface of Titan

By Leave a Comment

Prof. John Zarnecki

In the early hours of Christmas Day 2004, a small probe called Huygens separated from the larger spacecraft Cassini. Three weeks later, on 14 January, it descended through Titan’s atmosphere to make the most distant soft landing in the solar system to date. Huygens transmitted data during its 136 minute descent through the thick atmosphere and a further 130m minutes from the surface until Cassini disappeared below the horizon.

Prof. John Zarnecki was the principal investigator for the UK-based team that built the instruments that first made contact with the surface of Titan, Saturn’s largest Moon.

In this conversation, recorded in December 2020, Prof. Zarnecki recalls how the mission came about, the science Huygens revealed at the time and today, a decade and a half later. Cassini-Huygens was a joint mission between NASA and ESA. He also shares his views on the value of international collaboration in space.
