\t\t\t\t\t\t04\/10\/2024<\/span> ESA’s Hera asteroid mission will lift-off soon! Hera will launch on a SpaceX Falcon 9 rocket from Cape Canaveral Space Force Station in Florida, USA. The launch window opens on 7 October and teams on both sides of the Atlantic are currently hard at work carrying out launch preparations.<\/p>\n ESA will livestream the launch on ESA WebTV, ESA YouTube and on ESA\u2019s X, and\u00a0LinkedIn\u00a0accounts.\u00a0More details will follow as we receive confirmation of the launch date and time from the launch service provider.

We currently know of more than 35 000 asteroids whose orbits bring them close enough to Earth that we keep a close eye on them. ESA\u2019s Hera mission is part of the international effort to answer the question: could we do anything if we discovered one on a collision course?<\/p>\n<\/p><\/div>\n In September 2022, NASA\u2019s DART spacecraft impacted the asteroid Dimorphos in the first test of asteroid deflection, shifting its orbit around the larger asteroid Didymos. Now, ESA\u2019s Hera spacecraft is launching on a mission to perform a detailed post-impact survey of Dimorphos.<\/p>\n Using the suite of scientific instruments on the main spacecraft and its two CubeSat passengers, Hera will assess the effectiveness of asteroid deflection and help turn this grand experiment into a well-understood and repeatable planetary defence technique.<\/p>\n<\/p><\/div>\n Hera will be the first spacecraft to rendezvous with a binary asteroid system and its scientific survey of the target asteroids will greatly improve our understanding of how binary systems form and why they are so common.<\/p>\n The spacecraft will also demonstrate new technologies for autonomous spacecraft navigation and for close proximity operations in low-gravity environments.<\/p>\n<\/p><\/div>\n Hera is an ESA mission, and the first spacecraft developed under ESA\u2019s Space Safety programme. It features contributions from 18 European ESA Member States and the Japanese space agency JAXA has provided one of the spacecraft\u2019s scientific instruments. The global Hera science community overlaps significantly with that of NASA\u2019s DART mission.<\/p>\n<\/p><\/div>\n Once launched, Hera will begin a two-year cruise phase. An initial deep space manoeuvre in November 2024 will be followed by a Mars flyby that offers a rare and exciting view of Mars\u2019s moon Deimos in March 2025. A second deep space manoeuvre in February 2026 will line Hera up for arrival at the Didymos binary asteroid system. An \u2018impulsive rendezvous\u2019 in October 2026 will bring Hera into the vicinity of the asteroid system for orbit insertion.<\/p>\n<\/p><\/div>\n
