With this week’s delays to Artemis II and III, astronauts likely won’t walk on the moon until 2026 at the earliest. Also, weight-loss drugs, AI, clean-energy tech and more: digging into MIT Technology Review’s annual list with executive editor Amy Nordrum.NASA Once Again Delays Artemis Crewed Missions To the MoonThis week, NASA announced that it was delaying two of its planned crewed missions to the moon. Artemis II, which was scheduled to launch in November 2024, was pushed to September 2025. And Artemis III, originally planned for late 2025, is now looking at a September 2026 launch date. The Artemis campaign has faced challenges with its lunar landers, spacesuits, life-support systems, and the Orion capsule’s heat shield, according to NASA. When launched, Artemis II will swing around the moon and return to Earth, while Artemis III will land on the south pole of the moon, and will mark the first time humans have walked on the moon since 1972.Joining Ira to talk about this and other top science stories in the news this week is Casey Crownhart, climate reporter at MIT Technology Review. They talk about challenges facing the offshore wind industry, a Hawai‘i coal plant that was replaced by a battery farm, why AI weather forecasting is not ready for primetime, and a new discovery that giant apes went extinct earlier than we thought—and for a different reason.Top Technologies To Watch In 2024The technology world moves so fast, it can be hard to know what to pay attention to. Sometimes it’s helpful for someone to tell you straight up who the big players are, and what technologies really could change the world.Luckily for us, MIT Technology Review compiles an annual list of the 10 breakthrough technologies they say matter most. This year, that list ranges from super-efficient solar panels to weight-loss drugs, and AI in just about everything.Joining guest host Kathleen Davis to discuss this year’s list is Amy Nordrum, executive editor at MIT Technology Review based in Boston, Massachusetts.Transcripts for each segment will be available the week after the show airs on sciencefriday.com.

It’s no longer just the realm of science fiction: It’s possible that in our lifetimes, astronauts will go to Mars. NASA is doing a lot of technological preparation for this, but the key to the success of these missions will be the astronauts involved. As Mars space missions will require months or even years on the red planet, the agency wants to better understand how our bodies are affected by time in space.NASA recently launched the Complement of Integrated Protocols for Human Exploration Research, or CIPHER. This is a suite of 14 studies astronauts will undergo on the International Space Station, measuring everything from bone health to brain activity to vision changes.Joining Ira to talk about CIPHER and the hopes for health data collection is Dr. Cherie Oubre, CIPHER project scientist in NASA’s human research program based in Houston, Texas.Transcripts for each segment will be available the week after the show airs on sciencefriday.com.

In 2023, a flood of science journalists lost their jobs. At the same time, public trust in science continues to decline.Last year was a tough one for science journalism. National Geographic laid off all of its staff reporters, and Wired laid off 20 people. And the most recent blow came in November, when Popular Science announced it would stop publishing its magazine after a 151-year run, and laid off the majority of its staff.Beyond talented journalists losing their jobs, many people seem to be losing trust in science in general. A recent Pew Research Center survey found that only 57% of Americans think science has a mostly positive effect on society, down considerably since the beginning of the COVID-19 pandemic.Is the waning trust in science reflected in the shrinking of science journalism?Ira talks about the current state of science journalism with Deborah Blum, science journalist, author, publisher of Undark magazine, and director of the Knight Science Journalism Program at Massachusetts Institute of Technology and Sabrina Imbler, author and science reporter for Defector.Transcripts for each segment will be available the week after the show airs on sciencefriday.com.
