Professor Brian Cox fulfils a childhood dream by going behind the scenes at Nasa's Jet Propulsion Laboratory (JPL), mission control for Mars 2020 – one of the most ambitious missions ever launched that may finally reveal if life ever existed on the red planet. In 1980, a young Brian Cox wrote to JPL asking for photos from some of their missions to the planets. The pictures they sent him from Voyager and the Viking mission to Mars were a source of inspiration that set him on the path to becoming a physicist. Now, over 40 years later, he has been granted privileged access to JPL, including key mission areas that are usually off-limits to film crews. Brian spends a week following the team who guide the Perseverance rover and the Ingenuity helicopter - the first powered aircraft ever sent to another planet - across the surface of Mars during a critical stage of the mission. Perseverance's goal is to search for signs of long extinct life on the surface of Mars in an area called Jezero Crater, which, 3.8 billion years ago, was filled by a vast lake. If it finds evidence of that life, it could change everything we know about life in the universe - and even transform our understanding of our own origins.

In July 2022, the James Webb Space Telescope released its first images. They were visually stunning, and it was clear they provided more detail of stars, galaxies and planets than ever before. But for the scientists waiting on the data, this was just the beginning of their journey to discover what the new telescope would reveal. Since then, they have been working hard and publishing papers on all the data JWST has been sending back. Two years ago, just after the first images were released, Chris Lintott set off on a road trip to meet some of the scientists that were excitedly waiting on the first data. He wanted to find out what they hoped it could reveal. To mark the second anniversary Chris, along with fellow presenters Maggie Aderin-Pocock and George Dransfield, headed off to meet scientists old and new, to find out what the Webb Telescope has told us so far. Chris gives us a run-down of the highs and lows the Webb Telescope has been through and the other discoveries it has made. Maggie is off to Bristol University to revisit Dr Hannah Wakeford who has been using JWST data to reveal what interesting chemicals exoplanet atmospheres contain. George meets Professor Leigh Fletcher at the University of Leicester. When Chris met him two years ago, only one JWST image of Jupiter had been released. Now, he has data from all four of the outer planets of the solar system, and they have all thrown up surprises. JWST has revealed new jet streams on Jupiter and provided a greater understanding of its Galilean moons. Seasonal changes on Saturn have now been documented, and Uranus and Neptune have thrown up quirks that need another few years of work to understand. Chris also visits the University of Cambridge to meet Dr Sandro Tacchella, who has been part of a team looking back at some of the earliest galaxies. He explains what new light the JWST data can shed on ancient stars, and what that can reveal about how our cosmos formed after the Big Bang. Finally, our resident astronomer Pete Lawrence guides us through what there is to see in this month’s night sky, and how you too can look at some of the same targets as the James Webb Space Telescope – just not quite in the same level of detail!

"This film documents an event that has never taken place – man's first encounter with intelligent life from space". We've been fantasizing about an extraterrestrial visit for decades, but what would happen if it actually took place? How would we cope? Should we be afraid? These and many other questions are addressed in this philosophical film about a hypothetical initial contact with aliens. Scientists and space affairs specialists at the UN and NASA and in the British government cooperate in this cinematic simulation of the undoubtedly exciting meeting between extraterrestrial life and humanity. The interviewees speak directly to the unknown entities as if they've already arrived. From their own fields – politics, theology, sociology, biology or space science – they ask probing questions. What are you doing here? Do you have a sense of right and wrong? Do you carry bacteria that could make us sick? Are we hazardous to your immune system? Information specialists in the British government show how a first summit in this situation could go. How do you inform the public? Will countries work together? Is there a danger involved? Above all, the alien visit raises questions about the relation between our own history of exploration, colonization and warfare, and the expectations with which we approach the unknown. This is a journey beyond terrestrial perspective, revealing the fears, hopes, and rituals of a species forced not only to confront alien life forms, but also its own self image.
