Does Martin Luther King III still have a dream?

When Martin Luther King the third visited Australia earlier this year, we sat down with him to find out how he has harnessed his father’s dream of an oasis of freedom and justice now in the 21st century.   Martin Luther King III was ten years old when his father, the hero of the modern US civil rights movement, was assassinated for his advocacy against racism. King III has picked up his father's fight for a free and equal America, but is his father's dream still possible in 2026?  King joins Hamish Macdonald and Kylie Morris to talk about whether the spirit of non-violent resistance can help push back against ICE, his hopes that Trump abides by the law when it comes to the next Presidential election and what he would ask  his father if he were still alive today.

Prof Brian Cox on whether Elon Musk owns the moon

Since we first broadcast this episode in February, much has happened space wise; there was the NASA Artemis mission bringing a lunar colony closer to reality, Jeff Bezo’s rocket launch that exploded, Space X became the biggest IPO in history and Elon Musk reached beyond the skies as the world’s first trillionaire. But as tech billionaires compete for NASA contracts, from Elon Musk's SpaceX to Jeff Bezos' Blue Origins, can we trust corporations to act on humanity's behalf . Hamish Macdonald and Jonathan Webb (Lab Notes [https://www.abc.net.au/listen/programs/lab-notes]) speak to rockstar physicist Professor Brian Cox, about who owns space, and why tech billionaires are not the bad guys, but not the good guys either.

What does Trump actually want from Iran?

Back in February despite uprisings, sanctions and the ongoing conflict with Israel negotiations were underway between the US and Iran over its nuclear ambitions. Those negotiations saw Israeli Prime Minister Benjamin Netanyahu rushing to Washington to influence any potential deal. Two weeks later Israel and US made their first military strikes. A vital question at the time was: how does Iran sit within the wider region? And what deal did the US really want?  Today, despite ongoing negotiations for peace deal between Iran and the US those questions still stand. Geraldine Doogue and Hamish Macdonald are joined in studio by Vali Nasr, who advised the US State Department on Iran during the Obama era to talk about why Trump fell for his own saviour narrative, and how October 7 is still reshaping the region.
