SOHO marks 30 years of continuous solar observation from L1

On 2 December 1995 the ESA/NASA Solar and Heliospheric Observatory (SOHO) launched on a planned two‑year mission. Thirty years on, SOHO remains stationed about 1.5 million km sunward of Earth, providing an almost uninterrupted record of solar activity spanning roughly three 11‑year cycles.

Briefing

What Hype is tracking

  • Provides a 30‑year, near‑continuous solar dataset from L1 (≈1.5 million km), covering almost three 11‑year solar cycles — a unique baseline for solar physics and long‑term trend analysis.
  • SOHO’s archive underpins operational space‑weather forecasting and complements recent missions such as the launch of dedicated space‑weather probes and ESA’s Solar Orbiter close‑up observations.
  • Demonstrates the value of long‑running international science partnerships and sustained operations, a theme echoed by the ISS 25‑year milestone.
