Additionally, as more nations and corporations launch lunar missions and establish long-term infrastructure, cislunar space is increasingly becoming a strategic focus for exploration, logistics, and transportation.

Planetary Defense As The Ethico-Legal Gateway For International Space Security, Evie Kendal

Space and Defense

Following the news in late 2024 that there was a city-killer asteroid on a possible collision course with Earth, many members of the public were shocked to learn there was no reliable global plan for managing such asteroidal and cometary impact hazards. While calculations of Asteroid 2024 YR4’s trajectory were further refined to exclude the previously reported 2-3% chance of collision in 2032, this event highlighted a major security threat: the lack of a globally coordinated, appropriately resourced, and politically supported planetary defense strategy (Gibney, 2025). In so doing, it also provided an opportunity for security experts to consider the …

Space-Based Missile Defense With Early Interceptor Launch Strategies, William Priedhorsky, James Wells

Space and Defense

There is renewed interest in space-based boost-phase intercept (SBPI) for missile defense against ICBMs of near-peer adversaries. We discuss SBPI in the context of other missile defense approaches, and address one of its challenges, which is the expense of fielding a large enough constellation of interceptors in space to counter even a small number of ICBMs. We develop an early-launch approach that could substantively reduce the required density of interceptors. Because every second matters in boost-phase defense, early launch of interceptors can significantly increase the reach of each interceptor. Early launch would require interceptors that have highly throttleable motors. Our …

Golden Dome: Seeking Space Security, Namrata Goswami

Space and Defense

The “Golden Dome” initiative [formerly Iron Dome] was announced by President Donald Trump on January 27, 2025, signifying a transformative shift in global space security policy. It fundamentally questions long-standing assumptions about deterrence, national vulnerability to missile attacks, and the role of space in strategic defense. More importantly, it emerges at a moment of acute strategic transition: the erosion of Cold War arms control frameworks, the rapid advancement of hypersonic and orbital delivery systems, and the growing integration of space into warfighting doctrines. Launched via a presidential memorandum in January 2025, Golden Dome calls for a layered missile defense system …
