By coming as close as 5,000 km away from Mars, the planet\u2019s gravity shifted the spacecraft\u2019s trajectory towards its final destination, Dimorphos and the larger Didymos asteroid it orbits around. This manoeuvre shortened Hera\u2019s journey time by many months and saved a substantial amount of fuel.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>While performing yesterday\u2019s flyby of Mars, ESA\u2019s Hera mission for planetary defence made the first use of its payload for scientific purposes beyond Earth and the Moon.
