While artificial intelligence (AI) has enhanced or enabled technologies that were previously not thought possible, its increased presence has also engendered growing concern, particularly in domains where the potential for harm is high. Can a set of definitions and best practices help policymakers gain the confidence to pursue the benefits of AI while also ensuring the AI-enabled future?

Historically, the very low Earth orbit (VLEO) atmosphere has been a tough one for satellites to survive long-term. Can air-scooping electric propulsion (ASEP) potentially extend the life of VLEO satellites?

The concept of space-based solar power, also referred to as solar power satellites (SPS), has been evolving for decades. In 1968, Dr. Peter Glaser of Arthur D. Little, Inc. introduced the concept using microwaves for power transmission from geosynchronous orbit (GEO) to an Earth-based rectifying antenna (rectenna). Since then, technology has advanced on several fronts to remove some of the technological and economic barriers to practical full-scale implementation. U.S. decisionmakers are now facing a pivotal moment as several countries continue to invest in this promising, game-changing technology. This paper discusses the history of SPS, a few leading innovators, key functional components, and market applications. Ultimately, the United States must decide whether and how to invest in SPS to optimize the various operational, competitive, and societal benefits that this type of application offers to commercial, defense, and civilian markets.
