Episode 106 – ESA’s new science missions

By Leave a Comment

Pau McNamara

European Space Agency’s Dr Paul McNamara was studying low-frequency gravitational waves just before they were discovered in 2015. Now he is the astronomy and astrophysics coordinator for the European Space Agency. In this interview, recorded in Athens during Cospar2022, he speaks about some of the exciting science missions that ESA will be launching later this decade.

These missions include

  • Juice – JUpiter ICy moons Explorer
  • Euclid – To explore dark matter and dark energy
  • Plato – The next-generation planet-hunting mission
  • Ariel – A UK-led mission to explore the atmospheres of exoplanets

He also talks about ESA’s publicly available resources especially useful to science educators. Planetary Science Archive and ESA Sky. They are available to anyone, in or outside Europe and without charge. Links are available on this episode’s web page.

Episode 105 – Return to Titan – Dragonfly

By Leave a Comment

NASA’s Cassini-Huygens lander arrived at Titan on 14th January 2005. The first instrument to make contact with the surface of Titan was a penetrometer made by Ralph Lorenz. Since then he has gone on to write many books and work on several other projects.

Dr Ralph Lorenz

In this episode, he speaks about some of those projects, especially Dragonfly, a return mission to land on Titan. This mission, for which he is the mission architect, is like no other. It is not really a lander or rover but a quadcopter that will sample different regions near the landing site during its 3.3-year lifetime. Ralph talks about what we can expect from Dragonfly which launches in 2027 and arrives at Titan in 1934.

The documentary Destination Titan we refer to in this discussion is available here is available on Youtube here.

Episode 102 – Martian Geology with Prof Sanjeev Gupta

By Leave a Comment

In 1972, Harrison Schmitt became the first (and so far only), scientist to walk on the surface of the Moon. As a practising geologist, he brought a scientific perspective to understanding lunar geology. Since then many scientists have brought their scientific insights to understanding the surfaces of comets, asteroids, the planets in the solar system and their moons.

Professor Sanjeev Gupta

Professor Sanjeev Gupta is amongst the geologist helping to understand the martian surface today. Not from field trips to the martian surface but from data returned by martian landers, rovers and orbiters. In this interview recorded in July during COSPAR2022 in Athens, he describes his journey from revealing how the United Kingdom became an island to making sense of martian geology.

Episode 95 European Space Cooperation DeGaulle to ExoMars with Brian Harvey

The latest book from author Brian Harvey @BrianHarveyAut1, 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. 

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 on how collaboration in space 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.
