The arXiv white paper (preprint, not peer-reviewed) from Soldini et al. advocates UK-led autonomous rendezvous fleets to characterize NEOs, tying planetary defense directly to resource prospecting. Unlike single-spacecraft efforts, the REMORA-derived concept envisions low-cost, distributed missions that could map physical properties ground observations miss. Yet the proposal underplays execution risks: deep-space autonomy must handle unpredictable regolith behavior and communication delays exceeding 20 minutes, areas where even JAXA's Hayabusa2 encountered navigation surprises. Drawing on NASA's DART mission results (published in Nature, 2023; n=1 kinetic impact, limited to Dimorphos), deflection efficacy depends on precise mass and porosity data that fleet in-situ measurements would supply, yet the paper omits how commercial actors like AstroForge are already testing similar rendezvous tech outside government channels. ESA's Hera follow-up (peer-reviewed trajectory papers, 2024) further shows that international coordination often stalls on data-sharing protocols the UK proposal assumes will hold. Long-term, this approach could seed off-world supply chains by 2040, but only if regulatory frameworks address liability for deflected objects that later become mining targets, a civilizational risk dimension the white paper leaves implicit.
