Artemis II: NASA’s long road back to the Moon

Final preparations are underway for NASA’s Artemis II mission, the first crewed mission around the Moon for more than 50 years. Four astronauts, three men and one woman, will spend 10 days aboard the Orion spacecraft, going further into space than any other humans as they orbit the Moon and return to Earth. The mission is the next step of the Artemis programme, which plans to land astronauts back to the Moon by 2028. China has its own programme targeting a full crewed mission to the lunar surface by 2030. In this episode, we speak to Scott Pace, director of the Space Policy Institute at George Washington University about why the US is going back to the Moon. Pace worked in space policy for the George W. Bush Administration, followed by a stint at NASA before his appointment as the executive secretary of the National Space Council during the first Trump administration, where he worked on the launch of the Artemis programme. This episode was written and produced by Katie Flood and Gemma Ware was the executive producer. Mixing by Eleanor Brezzi and theme music by Neeta Sarl.

How the US cloned Iran's drones

The day after the US began bombing Iran, US Central Command confirmed it had used a new, cheap type of kamikaze drone called a Lucas for the first time in a combat operation. These drones were made in America, but their roots actually lie in Iran – they are reverse engineered copies of an Iranian drone called a Shahed that the Russians have also been using to bomb Ukraine. In this episode, PhD researcher and military expert Arun Dawson at King's College London explains how the Iranians developed the Shaheds, why the US decided to copy them, and what role these low-cost drones might play in the future of warfare. This episode was written and produced by Mend Mariwany and Gemma Ware was the executive producer. Mixing by Eleanor Brezzi and theme music by Neeta Sarl.

The Making of One Nation: the unlikely rise of Australia’s Pauline Hanson

From a fish and chip shop in regional Queensland to the heart of Australian politics: this is the unlikely story of One Nation, Australia's most controversial minor party. For thirty years, One Nation and Pauline Hanson have been ridiculed, dismissed and shut out. Now, no one is laughing. This week we're running the first episode of The Making of One Nation, a new series from The Conversation hosted by Ashlynne McGhee. She explores how a party built on fear and grievance thrived, died and rose again to upend Australian politics. Hanson's infamous 1996 maiden speech to the Australian Senate — warning that Australia was "being swamped by Asians" — still echoes through Australian political life. But who was Pauline Hanson before she became a phenomenon, and what did she actually represent? Was she a cause of a new kind of politics, or a symptom of one already forming? We hear from Anna Broinowski, documentary maker and senior lecturer at the School of Art, Communication and English at the University of Sydney, who made a documentary and wrote a book about Hanson. Follow The Making of One Nation to make sure you don't miss more episodes in the coming weeks. Sign up here for a free daily newsletter from The Conversation.

Was the Gulf blindsided on Iran?

As Israel and the US continued to bomb Iran after killing the country's supreme leader Ali Khamenei, Iran lashed out at its neighbours with multiple drone strikes, including against the US embassy in Riyadh. Saudi Arabia and Iran have a long and bitter rivalry. Yet, in recent years, the Saudis had begun building new diplomatic relationship with Iran, even as they and other Gulf states continued to host American military bases, and court American investment. Now the Gulf states find themselves in the middle of the very regional conflict many of its leaders hoped to avoid. It's one which threatens longstanding efforts to cement the Gulf as a hub for finance, travel and tourism, and as an oasis of security. Were they blindsided? Or did some actually want the US to attack Iran? With the US and Israel seemingly calling the shots, what will the Gulf states do now? In today's episode, we speak to Simon Mabon, a professor of international relations at Lancaster University in the UK and expert in Saudi-Iran relations, about how the Gulf's delicate balancing act between the US and Iran came toppling down. This episode was written and produced by Mend Mariwany and Katie Flood. The executive producers was Gemma Ware. Mixing by Eleanor Brezzi and theme music by Neeta Sarl.

Peering into the history of the universe: astronomers explain why the James Webb Space Telescope is such a big deal

With a mirror six and half metres in diameter, a sun shield the size of a tennis court and an instrument compartment bigger than a phone booth, the James Webb Space Telescope is enormous. After years of delays, it's now set for launch on December 22. We speak to two astronomers about the telescope and the questions they hope it will answer about the beginning of the universe and the conditions on exoplanets orbiting far-away stars. Featuring Martin Barstow, professor of astrophysics and space science at the University of Leicester in the UK and chair of the Space Telescope Science Institute Council; and Marcia Rieke, Regents professor of astronomy at the University of Arizona in the US and principal investigator on the near-infrared camera onboard the James Webb Space Telescope. In our second story, Edwin Kwong, a research fellow at the University of Melbourne in Australia, explains his recent research into the tactics used by the food industry to boost sales of ultra-processed foods in middle-income countries. And Luthfi Dzulfikar, an editor for The Conversation in Jakarta, Indonesia recommends some analysis on the recent volcanic eruption on the island of Java. The Conversation Weekly is produced by Mend Mariwany and Gemma Ware, with sound design by Eloise Stevens. Our theme music is by Neeta Sarl.

Is there a multiverse?

Interest in the multiverse theory, suggesting that our universe is just one of many, has spiked since the movie Everything Everywhere All At Once was released. The film follows Evelyn Wang on her journey to connect with versions of herself in parallel universes to stop the destruction of the multiverse. The multiverse idea has long been an inspiration for science fiction writers. But does it have any basis in science? And if so, is it a concept we could ever test experimentally? Featuring Andrew Pontzen, professor of Cosmology at University College London, Katie Mack, Hawking chair in cosmology and science communication at the Perimeter Institute for Theoretical Physics, and Sabine Hossenfelder, research fellow of physics at the Frankfurt Institute for Advanced Studies. This episode is presented by Miriam Frankel and produced by Hannah Fisher. Executive producers are Jo Adetunji and Gemma Ware. Social media and platform production by Alice Mason, sound design by Eloise Stevens and music by Neeta Sarl. A transcript is available here.

The 'national humiliation' behind Russia's war on Ukraine

As the 21st century dawned, a newly-elected Vladmir Putin was making friends on the world stage. He smiled for photo ops at G8 meetings, and was the first foreign leader to call George W. Bush after the attacks of 9/11, offering his support against terrorism. So what changed? To understand Russia's view of the world now – and its continued aggression towards Ukraine – it helps to know more about the psyche of the country and its leader. In today's episode, we talk to James Rodgers, a reader in international journalism at City St George's, University of London, about how a festering sense of national humiliation after the collapse of the Soviet Union hardened Putin's tough man regime and led Russia to turn its back on the west. This episode was written and produced by Mend Mariwany and Gemma Ware with editing help from Ashlynne McGhee. Mixing by Michelle Macklem and theme music by Neeta Sarl.

Fundamental constants: is the universe fine tuned for life to exist?

Imagine a universe with extremely strong gravity. Stars would be able to form from very little material. They would be smaller than in our universe and live for a much shorter amount of time. But could life evolve there? It after all took human life billions of years to evolve on Earth under the pleasantly warm rays from the Sun. Now imagine a universe with extremely weak gravity. Its matter would struggle to clump together to form stars, planets and – ultimately – living beings. It seems we are pretty lucky to have gravity that is just right for life in our universe. Featuring Fred Adams, professor of physics, University of Michigan, and Paul Davies, professor of physics, Arizona State University. This episode was presented by Miriam Frankel and produced by Hannah Fisher. Executive producers are Jo Adetunji and Gemma Ware.

Mystery covid methane spike solved

Six years ago, as countries around the world went into COVID lockdowns, the air got cleaner. Factories slowed down, roads emptied and aeroplanes were grounded. As people stayed home, the world burned fewer fossil fuels and so carbon dioxide emissions dropped. But something else was also happening in the atmosphere. Levels of methane, an extremely potent greenhouse gas that warms the planet even faster than CO2, rose faster in 2020 than at any point since records began in the 1980s. And methane levels kept on rising during 2021 and 2022. Ever since, scientists have been trying to piece together what caused this sudden mysterious increase in methane. Now, they think they have the answer – and it was partly due to COVID lockdowns. In this episode, we speak to Philippe Ciais, a researcher at the Laboratory for Environmental and Climate Science at Université Paris-Saclay in France, and one of the authors of a new study in the journal Science about the spike in methane levels, who explains how they solved the mystery. This episode was written and produced by Mend Mariwany and Katie Flood and Gemma Ware was the executive producer. Mixing by Eleanor Brezzi and theme music by Neeta Sarl.
