A European spacecraft is heading to check an asteroid after NASA purposely knocked it off its course greater than two years in the past.
The European House Company’s (ESA) Hera spacecraft lifted off on a SpaceX Falcon 9 rocket from Cape Canaveral House Pressure Station in Florida at 10:52 a.m. ET on Monday.
It is scheduled to conduct a “crash scene investigation,” researchers mentioned.
Hera’s mission will deal with the asteroid Dimorphos, the place a golf cart-sized spacecraft crashed on Sept. 26, 2022. That mission, referred to as the Double Asteroid Redirection Take a look at (DART), shortened Dimorphos’ orbit round Didymos, a much bigger asteroid, by 33 minutes, researchers mentioned.
The profitable mission was solely a take a look at of the idea — to see, if an asteroid sooner or later threatens to hit Earth, whether or not it may very well be pushed out of hurt’s method.
On a collection of flybys, Hera will survey Dimorphos’ mineral make-up and the mud surrounding it, the company mentioned. Its mission may also assist scientists perceive how large the crater is that was created in the course of the DART mission, which they are saying may assist in future asteroid deflections. Hera may also allow researchers to get a extra correct estimate of Dimorphos’ mass.
The highest ESA official referred to as Monday’s mission a “bold step” in ramping up the European company’s function in defending the planet.
“Planetary defence is an inherently international endeavour, and I am really happy to see ESA’s Hera spacecraft at the forefront of Europe’s efforts to help protect Earth,” ESA Director Common Josef Aschbacher mentioned in an announcement.
Whereas in house, Hera may also conduct experiments and take a look at “self-driving” navigation round each asteroids, the company additionally mentioned.
The asteroids are a part of a binary asteroid system by which Dimorphos, at about 530 ft throughout, orbits Didymos, about half a mile throughout. The 2 asteroids will not be a risk to Earth, based on NASA. Each got here inside roughly 6 million miles of Earth in 2022, based on the ESA.
Hera’s mission may also embody “the first detailed survey” of Didymos.
The spacecraft is ready to succeed in the asteroids within the fall of 2026, based on the ESA.
