The FT’s space industry editor Peggy Hollinger speaks to researchers about the physical and mental pressures astronauts would face living millions of miles from home and to scientists studying the suitability of Mars’ atmosphere and soil.

US President Donald Trump wants to “plant the stars and stripes on the planet Mars”. But more than 50 years on from the moon landings, America’s space agency, Nasa, is in disarray. Meanwhile, China is forging ahead with its own plans for manned missions to the Moon and perhaps to Mars. Who will win the race to the red planet? 

The FT’s space industry editor Peggy Hollinger speaks to former and current Nasa employees about the challenges facing the space agency, and to Jared Isaacman, Trump’s one-time nominee for Nasa administrator.

Elon Musk wants humans to settle on Mars, and his rocket company SpaceX is spending billions of dollars on developing the spacecraft to take us there. The ‘Starship’ is being designed to take astronauts back to the moon, and eventually, on to the red planet. But why is Musk so obsessed with building a colony on Mars, and is he really the man to take us there? 

The FT’s space industry editor Peggy Hollinger speaks to space experts and Mars enthusiasts about the pull of the red planet, both for scientists and explorers, and how realistic Musk’s vision for humanity as an interplanetary species really is.

AI models have learned to create their own music by harvesting millions of songs from the internet. But critics say they’re using musicians’ work without permission, and three major record labels are suing them for ‘copyright infringement on an almost unimaginable scale’. 

In the second episode of this two part series, the FT’s pop critic Ludovic Hunter-Tilney speaks to campaigners and lawyers about the legal battle over AI generators, and to artists about the growth of AI music on streaming platforms. How are AI generated songs racking up millions of listens? And should streaming platforms do anything to stop it?

Generative AI models trained on vast swaths of popular music can create songs almost indistinguishable from human-made work. For some, they represent the future of pop music. For others, they threaten to flood the world with ‘AI slop’, drowning out the work of human artists, stealing musicians' jobs, and ending the process of music-making as we know it. Is this just a case of technophobia? Or could AI music generators replace human musicians altogether?

In the first in a two-part series, the FT’s pop critic Ludovic Hunter-Tilney speaks to musicians and artists about the inventive power of generative AI in music, as well as the potential threat it might pose to musicians’ livelihoods and the music industry as a whole.

AI music generators - platforms that use artificial intelligence to create new, original music from scratch - can make songs that are almost indistinguishable from human creations. For some musicians, they’re the next frontier in music-making technology. But for others, they represent a grave threat, flooding the world with low-grade AI music, stealing the jobs of working musicians, and even spelling the end of the creative process as we know it. Is this just technophobia, or is music facing AI annihilation?

In a new two-part series, the FT’s pop critic Ludovic Hunter-Tilney explores the emerging world of AI music, and the impact it could have on the industry.

Tech Tonic is presented by Ludovic Hunter-Tilney. The producers are Lulu Smyth and Josh Gabert-Doyon. Edwin Lane is the senior producer, Flo Phillips is the executive producer. Sound design by Breen Turner and Samantha Giovinco. Original music by Metaphor Music. Manuela Saragosa and Topher Forhecz are the FT’s acting co-heads of audio.

Peter Thiel is unlike any other Trump tech bro. As well as a wildly successful investor, he’s seen as a thinker - the philosopher king of Silicon Valley. Thiel’s acolytes in the tech world and Washington include vice-president JD Vance but his relationship with the Trump camp is complicated. And there are still questions about what, if anything, he wants with the president.

In the final episode of this season of Tech Tonic, Murad Ahmed speaks to FT columnist Gillian Tett about Thiel’s political philosophy, and to Tabby Kinder, the FT’s West Coast financial editor, about his influence in Silicon Valley.
