    Astronomy Cast Ep. 759: The Commercial Space Program By Fraser Cain & Dr. Pamela Gay Streamed live on Jun 9, 2025. Humanity has turned its focus back to the Moon, sending a fleet of spacecraft to the lunar surface. Some are run by the government, but there's a whole new group of commercial landers bearing instruments to the lunar surface. Is this the future of lunar exploration? Space used to be a place occupied by government-funded and military missions, but today, we're seeing the rise... and fall (somersault, crash, and explosion) of missions with commercial design and funding.

Some of our favorite robots are rovers currently roving around the surface of the Moon & Mars. But there's some pretty tricky terrain out there and engineers are scheming up clever ways to explore other worlds inspired by life that crawls, slithers, hops and flies. As we explore more surfaces and more complex surfaces throughout the solar system, mission teams are designing robot explorers that don't sit still and also don't rove. In this episode, we're going to take a look at the new technologies that are allowing technology to get around.   SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.  Join at the Galaxy Group level or higher to be listed in our YouTube videos.  Thanks to: BogieNet, Stephen Vei, Jeanette Wink, Siggi Kemmler, Andrew Poelstra, Brian Cagle, David Truog, Ed, David, Gerhard Schwarzer, Sergio Sancevero, Sergey Manouilov, Burry Gowen, David Rossetter, Michael Purcell, Jason Kwong

Computers are getting smaller, faster and more capable, which has enabled an entirely mew class of satellites: CubeSats. A mission small enough that you can hold it in your hands, and yet powerful enough to even travel to other planets and send messages home.    Every year, our electronics seem to get smaller and more powerful, with today's smart watches being more fully featured than the computers Pamela and Fraser had as little kids. These tiny processors, sensors, and transmitters are allowing tiny satellites with powerful functionality, and today we take a look at how this is changing space exploration.    SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.

Gay When enormous stars detonate as supernovae they release a burst of neutrinos that can be the first sign of a coming explosion. Now, astronomers have built a network to watch for that flash of neutrinos, and help direct their telescopes for when the sky show begins. Supernovae explosions occur in stages, with neutrinos being emitted hours before photons. If we can accurately detect those neutrinos, we might just be able to get on target before the light show even starts.... Maybe.   SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon. Join at the Galaxy Group level or higher to be listed in our YouTube videos.

The Hubble Tension is a vexing problem, with astronomers measuring the expansion of the Universe at different points in its history and getting different results. Errors have mostly been ruled out, which leaves the potential for new physics. Has the strength of dark energy been changing over time? We thought Dark Energy was constant with time, but new results from DESI say maybe not, and honestly, if it wasn't constant the Hubble Tension would be a whole lot easier to solve.   SUPPORTED BY YOU!
