This Week in Space (Audio)

Rod Pyle is out this week, so Rick Jenet of the National Space Society joins Tariq Malik this week to talk about SpaceX's Starship Flight 13, which deployed new Starlink V3 satellites and stunned viewers when the ship survived reentry intact enough to float in the ocean for days afterward. They also discuss NASA's Roman Space Telescope, now just a month from launch, and an in-progress emergency effort to save the ailing Swift Space Observatory using a servicing spacecraft that is itself now experiencing technical trouble. Finally, they look into Boeing's continued Starliner delays and India's first successful private orbital launch via Skyroot Aerospace's Vikram-1 rocket. Tune in!

This week, we cover how Starship Flight 13 finally prepares to launch amid a legal battle over SpaceX's proposed land swap at Starbase, plus a Chinese Long March 3B rocket gets struck by lightning during liftoff, yet still delivers its satellite safely. Then, guests Dr. Pascal Lee and astrobiologist Dr. Penny Boston join the show to mark the 50th anniversary of Viking 1's landing on Mars and revisit the mission's groundbreaking life-detection experiments and the decades-long controversy over what they actually found. The conversation traces Mars exploration from the earliest Mariner flybys through Viking's ambiguous, still-debated results—later explained by perchlorates in the Martian soil—and the fierce scientific rivalry the findings sparked. Join us!

This week we're jumping into the space headlines for the past few weeks. It's been busy, and some exciting things are happening! A couple of companies are moving into the space solar power arena--something we've long advocated--and that's welcome progress. Starship is set to fly Starship test number 13, and a lot is riding on this--the system is overdue for some proof of concept to keep up with NASA's HLS contract. An exoplanet spotted a decade ago has shown signs of a potentially habitable atmosphere; there are landslides--big ones--on Pluto, and evidence of "space candy" sugars in an interstellar cloud are in the news. Finally, SpaceX is doubling down on their big defense contracts with a well-funded US Space Force. Join us for all the latest!

We've been hearing a lot about NASA's new moonbase plans, and they are ambitious. Starting with Artemis V (so far), the US plans to begin preparations for a permanent base situated in the south polar regions of the moon. Details are somewhat fluid, but one thing stands out: the poles are likely to be the most challenging places to set up shop in an already hostile environment. Planetary scientist Dr. Pascal Lee joins us to discuss moonbase siting options and why the poles may not be the best choice at first.
