- 1Nancy Grace Roman Telescope Doubles Mission Life on Less Fuel●Roman Telescope Saves Fuel, Doubles Mission https://hackaday.com/2026/09/30/roman-telescope-saves-fuel-doubles-mission/
The Nancy Grace Roman Space Telescope, NASA's upcoming wide-field infrared observatory, has reportedly extended its planned operational lifetime from five to ten years by adopting a fuel-efficient route to its observing point. Engineers achieved the doubling by conserving propellant during the journey to the Sun-Earth Lagrange point 2, giving astronomers far more observing time.
- 2Testing Coulomb's Law at Home Stays Surprisingly Hard●Testing Coulomb's Law and Similar Fundamentals Yourself Remains Tricky https://hackaday.com/2026/09/29/testing-coulombs-
Hackaday examines why independently verifying Coulomb's law and other basic physics fundamentals remains genuinely difficult for hobbyists, despite the experiments seeming simple on paper. Precision instruments, stray charges and environmental interference make reproducible results elusive. The piece argues that hands-on verification of foundational science is harder than textbooks suggest, a point drawing interest from the amateur science and education community.

Hackaday has published a new article examining how perspective projection works in 3D graphics, walking through the underlying mathematics that make three-dimensional scenes appear correctly on flat screens. The piece, tagged under graphics, 3D printing and programming, breaks down the projection techniques used by developers and hobbyists working in rendering and 3D printing workflows.
- 4Hackaday Highlights Simple Battery Recycling Streamlining Solution●Hackaday: A Simple Solution for Streamlining Battery Recycling https:// hackaday.com/2026/09/30/a-simp le-solution-for-s
Hackaday has published a piece describing a simple approach to streamlining battery recycling. The article is being shared among open-source and tech communities, though no specific details about the method or its developers are provided in the headline. Recycling of lithium-ion and other batteries remains a pressing challenge as discarded devices pile up worldwide.
