Hera is a planetary defense mission under development in the European Space Agency's Space Safety and Security program for launch in October 2024. It will rendezvous in late December 2026 with the binary asteroid Didymos and specifically its moon, Dimorphos, which was hit by NASA's DART spacecraft on Sept. 26, 2022 as the first deflection test of the asteroid. Hera's main objectives are the detailed characterization of the physical properties of Didymos and Dimorphos and of the crater produced by the DART mission, as well as the measurement of the momentum transfer efficiency resulting from the DART impact.
Hera è una missione di difesa planetaria in fase di sviluppo nel programma Space Safety and Security dell'Agenzia spaziale europea per il lancio nell'ottobre 2024. Si incontrerà alla fine di dicembre 2026 con l'asteroide binario Didymos e in particolare la sua luna, Dimorphos, che è stata colpita dalla navicella spaziale DART della NASA il 26 settembre 2022 come primo test di deflessione dell'asteroide. Gli obiettivi principali di Hera sono la caratterizzazione dettagliata delle proprietà fisiche di Didymos e Dimorphos e del cratere prodotto dalla missione DART, nonché la misurazione dell'efficienza del trasferimento del momento derivante dall'impatto di DART.

Abstract
Hera is a planetary defense mission under development in the European Space Agency's Space Safety and Security program for launch in October 2024. It will rendezvous in late December 2026 with the binary asteroid Didymos and specifically its moon, Dimorphos, which was hit by NASA's DART spacecraft on Sept. 26, 2022 as the first deflection test of the asteroid. Hera's main objectives are the detailed characterization of the physical properties of Didymos and Dimorphos and of the crater produced by the DART mission, as well as the measurement of the momentum transfer efficiency resulting from the DART impact.File | Dimensione | Formato | |
