Darmstadt, September 15
The European house company (ESA) signed a deal price 129 million euros ($154 million) on Tuesday to make a spacecraft for a joint venture with NASA how you can deflect an asteroid heading for Earth.
NASA is because of launch a spacecraft in June 2021 set on a collision course with the Dimorphos asteroid to check whether or not it could be doable to nudge objects that is likely to be threatening Earth onto a safer path.
ESA will then launch its spacecraft — named Hera after the Greek goddess of marriage — in October 2024 to map the ensuing impression crater and measure the asteroid’s mass, reaching the world in late 2026 for a six-month survey.
The mission is paying homage to the 1998 movie Armageddon, by which actor Bruce Willis performs a member of a crew despatched to destroy an asteroid to avoid wasting Earth.
“We want to try for the first time to steer an asteroid on its potential collision course with Earth,” ESA director Rolf Densing instructed Reuters tv.
Dimorphos has a diameter of 160 metre, concerning the width of the Great Pyramid of Giza in Egypt, which ESA mentioned was large enough to destroy a complete metropolis if it had been to hit Earth.
Hera, set to be solely the dimensions of a desk, ought to navigate autonomously across the asteroid whereas it collects knowledge. It may even launch mini satellites — 10 cm cubes which is able to be capable to fly a lot nearer to the asteroid’s floor.
Marco Fuchs, chief government of German house and know-how group OHB that may develop the Hera craft, mentioned attempting to divert an asteroid was like “playing billiards” and famous the problem of steering in the direction of such a small celestial physique.
“You have to steer very precisely, you have to find it first and then approach it in such a way that you can really observe what has happened as a result of the impact of the American probe,” he mentioned. Reuters
