2026/08/25

Some place in space. Hosted by Steve Nerlich. Dear Cheap Astronomy – What is the role of AI in space? AI simulates human decision-making and finds most practical usage in the sorting and analysing of various kinds of data. So. you can feed an AI program pictures of galaxies and the classifications they fit into and then the AI can then identify and classify new ones that you feed it. It's kind of like how Galaxy Zoo used to work, except with Galaxy Zoo it was actual crowd-sourced people that did the

http://www.astronomycast.com/archive/ From December 12, 2008. Hosted by: Fraser Cain (@frasercain) and Dr. Pamela L. Gay (@CosmoQuest) In the old days, astronomers had to beg for telescope time. They'd put together a proposal, convince observatories to gather data for them, crunch that data and release the results. No telescope, no results. But everything's different now. Fleets of robotic telescopes constantly scan the skies, building up a vast database of raw data about the Universe. Anyone who

Cheap Astronomy - Dear CA Ep. 137: Space Missions

The 365 Days of Astronomy ·

2026/08/11

Hosted by Steve Nerlich. We are still out there. Dear Cheap Astronomy – Why do some space missions last so long? So, we're all familiar with the stories of the Mars rovers, Spirit and Opportunity, landing with mission lifespans of 90 days, that then went on to rove the surface of Mars for 15 years. And the Voyager probes, launched in 1977, were supposed to have five-year missions, which are now going on 47 years and counting. So, what's going on? Is NASA just crap at predicting mission lifetimes?
