After 60 years of discussion, we may finally be making real, actionable plans to send a crew to Mars. One of the prime advocates for sending humans to the Red Planet has been Dr. Robert Zubrin, founder and president of The Mars Society. In 1990, he and David Baker worked up a plan called "Mars Direct," which took the core of then-current NASA planning and streamlined it into a more realistic, affordable approach. Since then, some of the key elements have been incorporated into NASA's Design Reference Missions, still the primary set of plans for reaching Mars. Join us for this fascinating discussion.

Crew-9 Return: Astronauts Wilmore and Williams returned to Earth via SpaceX Dragon with dolphins swimming around their capsule—spoiler alert: it was NOT AI generated! Isar Aerospace: A German company prepared for the first orbital launch from Norway's Andoya Spaceport SpaceX Record: Achieved fastest booster turnaround yet by flying the same booster twice within nine daysMain Topic: Mars Exploration with Dr. Robert Zubrin
Mars Direct Plan: Zubrin's revolutionary 1990 proposal using just two heavy-lift launches and in-situ resource utilization, influencing NASA's planning Purpose vs. Vendor-Driven: Critique of NASA's Artemis as "vendor-driven" rather than focused on the mission goal Current Opportunity: New potential for Mars exploration under the current administration, but it must be a national program Timeline Prediction: Realistic goals of uncrewed Starship on Mars by 2028 and humans by 2033 Scientific Value: First Mars Starship should carry substantial scientific payload instead of just a demonstration mission—no red Tesla Roadsters to Mars, please Planetary Protection: Strong case against the "anti-human aesthetics" of keeping Mars pristine Science Budget Concerns: Warning against proposed 50% cuts to NASA's science programs Starboat Concept: Proposal for a smaller ascent vehicle to complement Starship for more efficient Mars and Moon missions Moon vs. Mars Strategy: Design hardware primarily for Mars that can also work for lunar explorationHosts: Rod Pyle and Tariq Malik

In this episode of This Week in Space, Rod Pyle and Tariq Malik host Dr. Robert O'Brien, Director of the Universities Space Research Association's Center for Space Nuclear Research, for a fascinating deep dive into nuclear propulsion technology for space exploration. They discuss the history, current developments, and future potential of nuclear electric and nuclear thermal propulsion systems, which could revolutionize our ability to explore Mars and beyond—both robotically and with human crews.
Headlines
Crew-10 Launch Update: SpaceX's Dragon Endurance prepared to launch relief crew for ISS, addressing delays and setting stage for Williams and Wilmore's return. NASA Layoffs: NASA shuttering several offices including Technology Policy and Strategy, Chief Scientist, and diversity initiatives to comply with Trump administration executive orders. Saturn's Moon Count: 128 additional moons discovered orbiting Saturn, bringing total to 274 (surpassing Jupiter's 95), raising questions about moon classification criteria. Lunar Eclipse: First total lunar eclipse of 2025 visible across western hemisphere, with another eclipse in September for viewers in Asia and Australia. New Space Billionaire: Eric Schmidt, former Google CEO, takes over as CEO of Relativity Space (a 3D printing rocket company), joining Bezos, Musk, and Branson in the space industry.Main Topic: Nuclear Propulsion with Dr. Robert O'Brien
Propulsion Types: Dr. O'Brien explained two main types: nuclear electric propulsion generates electricity for electric thrusters, while nuclear thermal propulsion heats propellant directly through a fission reactor for thrust. Efficiency Advantages: Nuclear systems offer greater efficiency than chemical rockets, potentially reducing Mars mission mass to one-third or less while enabling "maneuver without regret" capability. Historical Context: US launched SNAP-10A reactor in mid-1960s; Rover-NERVA program demonstrated nuclear thermal rocket technology before cancellation after Apollo. Current Development: Working to regain 1960s capabilities while implementing modern safety protocols, testing procedures, and materials science improvements. Safety Considerations: Modern development includes full exhaust containment and comprehensive safety measures, with waste containment as the primary focus. AI Applications: AI could accelerate development through materials optimization, autonomous operation for deep space, and enhanced reactor control safety. Fusion Propulsion: Remains promising future technology potentially enabling interstellar travel, with growing international investment. Project Orion: Historical nuclear pulse propulsion concept using small nuclear explosions for thrust - impractical for Earth launches but potential for interstellar applications. Public Education: Addressing concerns requires transparent communication, moving away from the "veil of mystery" of earlier nuclear programs. Educational Outreach: The Universities Space Research Association is developing a talent pipeline for "unicorn capabilities" in space nuclear expertise.Hosts: Rod Pyle and Tariq Malik

Does OpenAI have the capability for creative writing? Would you want to be coached in gaming through AI? What is Apple planning for its possible operating system redesign? And does AI have inconsistencies when providing the correct information to search queries?
Amanda Silberling of TechCrunch joins Mikah Sargent this week. Amanda talks about OpenAI and Sam Altman's social media post about how OpenAI is good at creative writing. Mikah talks about Microsoft's plan to launch Xbox Copilot, an AI-powered gaming assistant that can offer tips, guides, and information about the games you are playing. Mark Gurman of Bloomberg stops by to talk about Apple's plans to dramatically overhaul the look of its operating systems with the next iterations of iOS, iPadOS, and Mac OS. And Mikah talks about a study from the Tao Center and how AI systems are frequently providing incorrect information and citations from various sources and news articles.Hosts: Mikah Sargent and Amanda Silberling

Mikah Sargent dives deep into Archive Utility on macOS, a powerful but often overlooked tool that works behind the scenes to compress and expand files on your Mac. From creating basic zip archives to encrypted files, this episode reveals all the hidden features of this versatile utility.
How compression works - Compression algorithms look for repeating patterns in data to make files smaller, though already compressed files like JPEGs may not benefit much. Quick compression with right-click - The fastest way to compress files is selecting them, right-clicking, and choosing "Compress," which always creates a standard zip file. Opening Archive Utility - Access it directly by using Command+Space and typing "archive" to explore its full capabilities beyond the right-click option. Archive Utility settings - Configure where expanded files are saved, what happens to archives after expansion, and whether to automatically expand nested archives. Expansion options - Choose to keep, trash, or delete archives after expanding them, or move them to a specific location. Compression options - Similar settings exist for what happens to original files after creating an archive. Archive formats explained - Despite setting preferences in Archive Utility, the right-click "Compress" option always creates zip files regardless of settings. Creating CPGZ archives - These compressed archives must be created by selecting a folder through the File menu, not through right-click compression. Regular archives (CPIO) - Simple "briefcase" archives without compression, useful for bundling files without reducing size. Apple Archive (AAR) - A Mac-specific format that uses multi-threaded compression to efficiently compact files. Encrypted archives (AER) - Secure, password-protected archives that can be unlocked with Touch ID if saved to your keychain. Why ZIP remains the standard - ZIP format is used for the right-click compression option because of its universal compatibility across different operating systems.Zip and unzip files and folders on Mac - https://support.apple.com/guide/mac-help/zip-and-unzip-files-and-folders-on-mac-mchlp2528/mac
