Would meeting an extraterrestrial civilization be good or bad for humanity? Astronomer Dr. Jacob Haqq Misra argues that knowing the outcome in advance is fundamentally impossible, which results in a range of policy implications. Should we camouflage Earth's technosignatures or pour money into perhaps the most transformative event in human history? Should we fear the dark or embrace the unknown?  Discover more at: https://www.planetary.org/planetary-radio/2023-spe-policy-implications-of-active-setiSee omnystudio.com/listener for privacy information.

Prior to Starship's inaugural launch, environmental policy expert Eric Roesch was outspoken about the possibility of catastrophe. As the rocket launched, it kicked up massive clouds of dust and decimated its launchpad, scattering large chunks of concrete into delicate marine and coastal sanctuaries nearby. Eric blames both SpaceX and its regulatory body, the Federal Aviation Administration (FAA), for allowing the company to skirt responsibility in its environmental reporting and mitigating its impact on its surrounding wilderness. He joins the show to discuss the proper role of environmental regulations, why he believes the FAA was irresponsible in approving SpaceX's launch licenses, and how you can simultaneously protect the environment and local wildlife while still pursuing an ambitious path to space.
