The 2030s Roadmap — Part 6: CMB-S4 and the cosmological mass measurement
A 30 meV precision on Σm_ν by 2032. CMB-S4's cosmological neutrino-mass measurement will essentially settle the absolute mass scale.

Open Questions — Part 3: The absolute neutrino mass scale
Oscillation gives us mass-squared differences. But what is the lightest neutrino's actual mass? KATRIN, Project 8, CMB-S4 — and 0νββ in parallel — are closing in on the answer.
CMB-S4: the next-generation cosmology experiment that will weigh the neutrinos
Over the next decade, a network of telescopes at the South Pole and in the Chilean Andes will map the cosmic microwave background with unprecedented precision. Among the consequences: a measurement of the total neutrino mass to within 30 meV, possibly closing the question for good.
