Abstract In-space manufacturing technologies are considered vital for enabling advanced space missions and addressing logistical limitations of space exploration. While additive manufacturing has progressed rapidly, it still falls short of delivering the ultra-smooth surfaces required for optical elements. Fluidic Shaping is a novel method that harnesses surface tension under microgravity to form optical components with exceptionally smooth surfaces.

Abstract Future long-duration space missions will require in-situ, on-demand manufacturing of tools and components. Photopolymer-based processes are attractive for this purpose due to their low energy requirements, volume efficiency, and precise control of curing. However, photopolymerization generates significant heat, which is difficult to regulate in microgravity where natural convection is absent, leading to defects such as surface blistering and deformation.

From Observation to Insight: How Space-Based Data Reshapes Decisions on Earth

The Strait of Hormuz from space, a deceptively simple view of a global pulse point. Captured from orbit by Eytan Stibbe. Looking down at Earth from space, the view can be deceptively serene. Take the Strait of Hormuz for example. From 400 kilometers up, it looks like a simple photographic map. We see a narrow stretch of water, a defined coastline, a quiet passage between land masses. But in reality, that narrow stretch of water is anything but simple.
