Global pact for planetary defence as Ramses targets Apophis

ESA and JAXA signed memoranda to deepen planetary-defence collaboration and advance the Ramses mission to rendezvous with asteroid Apophis ahead of its 2029 Earth flyby, with ESA leading spacecraft design and JAXA contributing key hardware to study tidal effects and improve deflection knowledge; the 2029 flyby will bring Apophis within about 32,000 km of Earth, presenting a rare science and public-engagement opportunity.
