Could A Planet Like Arrakis From ‘Dune’ Exist?

“Dune: Part II” is one of the year’s most highly anticipated films, and it picks up where the first film left off: with Paul Atreides escaping into the desert on the planet Arrakis. It’s a scorching-hot world that’s covered in dunes, and home to giant, deadly sandworms.

Obviously “Dune” and its setting are fictional, but could there be a real planet that resembles Arrakis? And if so, could it sustain life?

Ira talks with Dr. Mike Wong, astrobiologist and planetary scientist at the Carnegie Institution for Science, about what Arrakis’ atmosphere is like, the search for life in the universe, and what sci-fi films get wrong—and right—about alien planets.

Preparing Astronauts For The Loneliness Of A Mars Mission

NASA is preparing to send humans to Mars. Although the launch date has been pushed back over the years, the agency says it wants to get there in the 2030s. And it has a lot on its to-do list. NASA needs to build new rockets, new habitable living spaces, new spacesuits, and new radiation shielding, just to name a few items.

But what if the one of the biggest challenges of these missions is not the engineering, but the mental health of the astronauts? Can all of the crew members get along with each other and stay alive over the course of three years in tight quarters and unforgiving environments? How will they cope with being separated from their families and friends for so long? And what lessons can they learn from astronauts who’ve lived on the International Space Station—and from our collective experience of isolation during the pandemic?

A new documentary, out March 8, explores all these questions and more. It’s called "The Longest Goodbye," and it dives into NASA’s Human Factors program, which includes a group of psychologists who are trying to figure out the best way to preserve astronauts’ mental health on a long and demanding mission.

SciFri producer and host of Universe Of Art, D. Peterschmidt, spoke to the film’s director, Ido Mizrahy, and one of its featured astronauts, Dr. Cady Coleman, about how NASA is thinking about tackling loneliness in space and what we can learn from astronauts who’ve already lived on the space station.

Should The Aliens In “65” Have Known About Earth’s Dinos?

Some science fiction movies, like “Alien,” are instant classics. A good sci-fi movie weaves together themes of science and technology with a gripping narrative structure to create a memorable story that leaves the viewer with something to think about. But some (many) sci-fi movies leave the viewer with one thought: “Huh?”

The 2023 movie “65” is in some ways a reversal of “Alien.” Instead of humans coming to an alien world and getting attacked by aliens, in “65,” an alien that existed 65 million years ago crash lands on Earth and gets attacked by dinosaurs. Oh, and the alien is Adam Driver. What’s not to get?

Sometimes, calling in a real-life scientist is the best way to wrap your head around science fiction. Dr. Lisa Kaltenegger, an astrobiologist at Cornell University, says that if there were advanced extraterrestrials near Earth during the age of the dinosaurs, our planet’s life should have been no mystery to them. That’s because around 300 million years ago, Earth’s atmosphere had abundant oxygen and methane, two of the building blocks of life. Kaltenegger’s own research has shown how Earth’s atmosphere during that period would have been visible through a telescope—and indicated an even stronger potential for life than Earth’s atmosphere today. She also saw “65” on a plane.

Based on Kaltenegger’s research, should Adam Driver have seen those dinosaurs coming? In an interview with Digital Producer Emma Gometz, she shares how telescopes can spot exoplanet atmospheres, why Jurassic Earth’s atmosphere was special, and a few of her thoughts on “65.”
