In this episode, Michael talks with Dan Katz, the CEO and co-founder of Orbital Sidekick, launcher and operator of hyperspectral imaging satellites that keep an eye on methane emissions from space. Dan shares his fascinating journey from having a background in STEM, physics, and astronomy to co-founding Orbital Sidekick. The company, which started as a bootstrapped venture in Dan's garage, now pioneers in leveraging hyperspectral imaging technology. This advanced tech is used on satellites to monitor energy infrastructure, particularly focusing on oil and gas pipelines.The conversation takes a technical turn as Dan explains the nuances between hyperspectral and multispectral imaging. He sheds light on how these techniques play a pivotal role in analyzing Earthbound emissions. The discussion also touches upon the challenges Orbital Sidekick faced, transitioning from a garage setup to launching a hyperspectral camera system on the International Space Station.Open-source technologies and the role of 3D rapid prototyping in space technology development are also explored. Dan emphasizes the importance of industry heritage and the collective knowledge that has shaped the space tech industry.The aerospace industry's evolution is another highlight of the conversation. With the advent of reusable rockets and increased accessibility for scheduling launches, the landscape of space missions has transformed. Both Michael and Dan discuss the significance of these advancements and their impact on the future of space exploration.Radiation challenges in space travel, especially concerning interplanetary journeys, are also discussed. Michael shares insights on the risks of scuba diving and draws parallels with the significance of the Van Allen Belt in low Earth orbit. The episode concludes with a reflection on the potential colonization of Mars, emphasizing that Earth, despite its challenges, remains the most hospitable option.
