Episode 103 -Observing the Solar System with the JWST

By Leave a Comment

The James Webb Space Telescope has already wowed astronomers and the general public with some incredibly spectacular deep space images. But did you know, NASA has set aside a substantial number of hours for JWST to observe the objects in the solar system? What’s more that programme kicks in this autumn so some images of planets and their moons along with asteroids and comets will be published before the end of this year.

Dr Connr Nixon

A team of astronomers including planetary scientist Dr Connor Nixon will make use of the Guaranteed Time Observations (GTO) to observe the objects in the solar system from Mars and beyond. JWST cannot look towards the Sun so excludes the Earth, Venus or Mercury. The program is led by Dr. Heidi B. Hammel.

In this interview recorded in July during COSPAR2022 in Athens, Connor Nixon talks about the GTO and his role in it looking at Titan.

Episode 93: Exploring the surface of Titan

Prof. John Zarnecki

In the early hours of Christmas day 2004, a small probe called Huygens separated from 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 on the surface of Titan, Saturn and the solar system’s largest Moon.

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

Episode 57: 15 October 2012 – Cassini Huygens Mission

By Leave a Comment

Launched 15 years ago today, the Cassini Huygens mission has been one of the outstanding successes of solar system exploration and a model of NASA ESA collaboration.

In episode 14 Professor John Zarnecki spoke about the science conducted from the surface of Titan by the Huygens lander in January 2005.

The European Space Agency’s Huygens probe had hitched a lift to Saturn aboard the Cassini orbiter. Six years after its arrival at Saturn, Cassini is still making spectacular discoveries about Saturn, its majestic rings and its many moons.

In this episode, Professor Carl Murray from Queen Mary University London talks about some of those discoveries and how the mission will eventually come to an end.

This interview was recorded during the National Astronomy Meeting in Manchester in March 2012.
