Heliocentric Confirmation
Scientists confirm the impact changed the entire system's orbit around the sun.
Hera Mission Launch
ESA launches the Hera spacecraft to conduct a post-impact survey.
Kinetic Impact
DART successfully strikes Dimorphos, the moonlet of the Didymos system.
DART Launch
NASA launches the DART spacecraft aboard a SpaceX Falcon 9 rocket.
New data confirms NASA's Double Asteroid Redirection Test (DART) successfully altered the orbital path of the entire Didymos-Dimorphos binary system around the sun. This milestone marks the first time human activity has intentionally modified the trajectory of celestial bodies on a heliocentric scale.
This page surfaces every story mentioning ESA across our space & defense coverage. We track each entity's appearance over time so readers can trace how the narrative evolves — which developments are isolated incidents, which build into longer arcs, and which reframe how operators in the space think about the entity. Story selection uses the same multi-source verification gate applied across the rest of our coverage.
Read our editorial methodology for how we identify, deduplicate, and score entity references. Our glossary defines the technical terms used across stories on this page, and our trends index contextualizes individual developments against the longer-running space & defense beat. Cross-entity comparisons live on our compare view.
