Clumpy Soil on Mars, What's a Lander to Do? Two weeks ago, the world marveled when the Phoenix survived a 420 million-mile space journey and landed on Mars, right where it was supposed to. Now it's expected to analyze Martian soil to determine whether there might have been life on that planet. The lander has a robotic arm that has scooped up Martian soil for analysis by instruments, including a miniature oven. But the dirt sample has turned out to be clumpier than the oven's filter could handle. Michael Hecht heads one of the Jet Propulsion Laboratory's two soil analysis team.
Trump plays scolder-in-chief with NATO allies At the opening of NATO’s dramatic new headquarters in Brussels today, President Trump acknowledged that Article 5 — promising that “an attack on one nation is an attack on all” -- has only been invoked one time: in the aftermath of September 11. But the President failed to provide what 27 other Alliance members have been waiting for: a re-commitment by America’s new leader to Article 5. Instead, they got a scolding.
What happens when America retreats from the world? Is President Trump taking his "America First" agenda to extremes, withdrawing the country from the international stage on trade and climate change, distancing America from its traditional allies across the Atlantic and even threatening to physically isolate the country through the building of a wall along its southern border? León Krauze guest hosts.
