- 4Hacker News·8/21/2026researchStudy finds Hubble’s radiation damage is out of phase with the solar cycle
A recent arXiv paper reports that radiation damage patterns in the Hubble Space Telescope have been offset from the solar cycle by about 4.3 years. The result suggests the telescope’s degradation is influenced by delayed or indirect effects rather than tracking solar activity in lockstep.

The article describes Sandia National Laboratories' effort to recreate the Intel 8085 as a radiation-hardened CMOS chip, resulting in the SA3000. It explains the engineering challenges of converting an HMOS design to CMOS, the higher transistor count, and the support chips Sandia produced for use in harsh environments such as space and defense systems.
