This event provides a unique opportunity to study the asteroid's physical and dynamical changes under strong tidal forces. The experiment leverages a combination of Earth-based radiometric measurements, optical imaging, and inter-satellite links between the RAMSES mothercraft and deployable subcraft in proximity to Apophis. Using high-precision Doppler and optical navigation data, the RSE aims to estimate the asteroid's ma","authors_text":"Andrea Negri, Edoardo Gramigna, Giacomo Paialunga, Giovanni Cucinella, Lorenzo Simone, Marco Zannoni, Paolo Tortora, Pier Luigi De Rubeis, Riccardo Lasagni Manghi","cross_cats":["astro-ph.EP"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.IM","submitted_at":"2025-03-25T18:32:33Z","title":"A Radio Science Experiment for the Ramses Mission to Apophis"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2503.19998","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:a28315fb9c476613592284f3587d5ed9572d5136ce638a9a69668ab272870f6e","target":"record","created_at":"2026-07-05T10:39:29Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"2eaa56e4a283bb16bb24dd91344b7a1d8310abe72d66b35b16ce3869d9fd9a95","cross_cats_sorted":["astro-ph.EP"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.IM","submitted_at":"2025-03-25T18:32:33Z","title_canon_sha256":"aa82e00c917790ecd9a63b42e15e29831fd33cf0ab22a1cd32c744dfac9e4829"},"schema_version":"1.0","source":{"id":"2503.19998","kind":"arxiv","version":1}},"canonical_sha256":"7f39eea5dc654e7d57f5258a3a1726e7c7af6d6c55c60a8cdc6d73d11bd6aaf2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7f39eea5dc654e7d57f5258a3a1726e7c7af6d6c55c60a8cdc6d73d11bd6aaf2","first_computed_at":"2026-07-05T10:39:29.881584Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:39:29.881584Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"kwccdEgUPaa/lpYrejh4Pn70LdxjVofVYrkMvj6npLG3kUUg0s0cuPVnAY5ghQbP3E64cc445rZEFD7YvloHAA==","signature_status":"signed_v1","signed_at":"2026-07-05T10:39:29.882056Z","signed_message":"canonical_sha256_bytes"},"source_id":"2503.19998","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a28315fb9c476613592284f3587d5ed9572d5136ce638a9a69668ab272870f6e","sha256:b9140103c650b9fd8708d2acb293049db1609970a55e51573e4d2d81820134a3"],"state_sha256":"8c9f8f2d50d18df334c3d800623609574d5d9fe370e86bcf6e90166dcfe6def5"}
