EU Clean Aviation to fund €60m for ground demonstrators of hybrid-electric narrowbody powerplants

The EU's Clean Aviation programme will provide €60 million (about $70.3 million) to support ground demonstrators of hybrid-electric narrowbody powerplants, with funding potentially shared by up to three engine manufacturers. The ground-based rigs are intended to validate propulsion technologies targeted at future narrowbody efficiency gains.

Spaceflight’s Atmospheric Footprint: Early Science and Major Unknowns Spaceflight’s returns—reentries, stage drops and spent hardware—deposit burned and vaporised particulates and metals into the upper atmosphere. Early science maps emissions and chemical impacts but large uncertainties remain about cumulative deposition, climate effects and whether industry growth demands regulatory controls.

Ice‑nucleating exhaust additives proposed to shorten contrails and curb aviation’s near‑term warming A U.S. researcher proposes adding ice‑nucleating particles to jet exhaust to alter contrail microphysics, accelerating ice crystal growth and evaporation to shorten contrail lifetime. The approach aims to reduce contrails’ radiative forcing and near‑term climate impact but would need environmental, safety and regulatory review.

ANA and Japan’s space agency mount sensors on passenger jets to track greenhouse gases ANA Holdings and Japan’s space agency are accelerating a program to mount atmospheric sensors on commercial passenger jets to improve monitoring of greenhouse‑gas emissions. The initiative will collect in‑flight environmental data from routine services to bolster national emissions observation efforts.

EU adopts 90% emissions cut by 2040 — new aviation mandates to hit airlines, hotels and cruises The EU has adopted a climate law mandating a 90% cut in greenhouse gas emissions by 2040 versus 1990 levels. The package includes new aviation mandates, building rules and a softened car ban that will drive compliance costs and operational changes for airlines, airports, hotels and cruise operators.

Sentinel‑6B returns first ocean altimetry data and begins ultra‑precise sea‑level mapping Launched in November, Copernicus Sentinel‑6B has reached orbit and returned its first ultra‑precise ocean altimetry maps, showing sea‑level variations across the North Atlantic and U.S. East Coast. The satellite will extend the decades‑long global sea‑level record and improve marine forecasting, coastal monitoring and related services.
