    Nov 24, 2022 · On 19 November, asteroid 2022 WJ1 became one of the many small asteroids to strike Earth, but only the sixth we ever saw coming. For the second time this year, humankind predicted an asteroid impact. The ~1-m rock caused no harm and burnt up in the sky above Toronto as a striking fireball.

    • Never seen anything like it. “In January this year, we became aware of an asteroid with the highest ranking on the Palermo scale that we’ve seen in more than a decade, reaching -0.66” explains Marco Micheli, astronomer at ESA’s NEOCC.
    • Planetary defenders – always alert. On 7 January, one day after its discovery by the Catalina Sky Survey, asteroid 2022 AE1 was flagged for a potential future impact by the Asteroid Orbit Determination (AstOD) automated system that makes up part of the NEOCC’s suite of tools to assess the asteroid risk.
    • The Sun never rises on ESA’s eyes on the sky … On the evening of Saturday 8 January, Marco ‘the impactor killer’ Micheli got hold of the 80 cm Schmidt telescope in Calar Alto, which the Coordination Centre has nearly continuous access to (weather permitting), to get more data.
    • … until the Moon gets in the way. During a tense week over 12-19 January, 2022 AE1 couldn’t be seen as the Moon outshone the dim potential impactor. On top of this, the asteroid was moving further away in its current orbit and getting fainter at the same time.

    Sep 22, 2024 · NASA’s DART spacecraft collided with the smaller body of the Didymos binary asteroid system in October 2022. ESA’s Hera mission will survey ‘Didymoon’ post-impact and assess how its orbit has been changed by the collision, to turn this one-off experiment into a workable planetary defense technique.

    In the world’s first test of asteroid deflection, ESA’s Hera mission will perform a detailed post-impact survey of the asteroid Dimorphos – the orbiting Moonlet in a binary asteroid system known as Didymos. NASA’s DART mission will impact the moonlet in September 2022, after which Hera will turn the grand-scale experiment into a well ...
