King Charles was granted five-star rank in each branch of Australia's armed forces Saturday, a ceremonial gesture to mark the first full day of his landmark tour Down Under.

Charles, in addition to being king of realm can now call himself field marshal of Australia's army, marshal of its airforce and admiral of the fleet.

It was not a bad day's work for the 75-year-old monarch, who spent Saturday recuperating and without public engagements after a marathon flight from London to Sydney.

The monarch -- who received the life-changing cancer diagnosis just eight months ago -- and Queen Camilla have begun a nine-day visit to Australia and Samoa, the first major foreign tour since being crowned.

They landed in Sydney on Friday and were greeted by local dignitaries and posy-bearing children, before a quick private meeting with Australia's staunchly republican Prime Minister Anthony Albanese and his fiancée.

"We are really looking forward to returning to this beautiful country to celebrate the extraordinarily rich cultures and communities that make it so special," the royal couple said in a social media post ahead of their arrival.

Royal tours to far-flung domains are a vital way of kindling local support for the monarchy, and the political stakes for the royals are high.

A recent poll showed about a third of Australians would like to ditch the monarchy, a third would keep it, and a third are ambivalent.

Visiting British royals have typically embarked on weeks-long visits to stoke support, hosting grand banquets and parading through streets packed with thrilled, flag-waving subjects.

This visit will be a little different. The king's health has caused much of the usual pomp and ceremony to be scaled back.

A planned stop in New Zealand was cancelled altogether, and he will be in Sydney and Canberra for just six days before attending a Commonwealth summit in Samoa.

There are few early morning or late night engagements on his schedule and aside from a community barbecue in Sydney and an event at the city's famed Opera House, there will be few mass public gatherings.

There had been rumors that he may attend a horse race in Sydney on Saturday, but he was not to be seen.

When the time came the well-hydrated crowd belted out Australia's anthem "Advance Australia Fair" rather than the royal anthem "God Save the King".

- 'Old white guy vibes'-

It is not just age, jetlag and health worries that the king has to contend with Down Under.

Australians, while marginally in favor of the monarchy, are far from the enthusiastic loyalists they were in 2011 when thousands flocked to catch a white-gloved wave from his mother Queen Elizabeth II.

"I think most people see him as a good king," said 62-year-old Sydney solicitor Clare Cory, who like many is "on the fence" about the monarchy's continued role in Australian life.

"It's a long time. Most of my ancestors came from England, I think we do owe something there," she said, before adding that multi-cultural Australia is now more entwined with the Asia-Pacific than a place "on the other side of the world".

Some are less charitable, seeing no reason to retain a king whose accent, formal get-up and customs have little to do with the daily lives of easygoing antipodeans.

"He just gives old white guy vibes," said home school teacher Maree Parker. "We don't need a king and queen, we can just do our own thing."

- The lucky country -

Still, Australia is a land of many happy memories for Charles, and he can be sure to find some support.

He first visited as a gawky 17-year-old in 1966, when he was shipped away to the secluded alpine Timbertop school in regional Victoria.

"While I was here I had the Pommy bits bashed off me," he would later remark, describing it as "by far the best part" of his education.

Bachelor Charles was famously ambushed by a bikini-clad model on a later jaunt to Western Australia, who pecked him on the cheek in an instantly iconic photo of the young prince.

Meteorites - rocks that fall to Earth from space - have pelted our planet from its birth about 4.5 billion years ago to today, often causing scant damage but sometimes triggering cataclysms. But from where exactly are these space rocks coming? New research has the answer, according to Reuters.

By studying the composition of meteorites that have landed over the years and the asteroids populating our solar system, astronomers have determined that about 70% of known meteorite impacts came from just three groups of asteroids residing in our solar system's main asteroid belt between Mars and Jupiter.

In total, the researchers in three different studies have now been able to account for the origins of most of the tens of thousands of known meteorites that have landed on Earth.

As part of the research, the astronomers carried out numerical simulations that enabled them to model the formation and evolution of families of asteroids orbiting the sun in the main asteroid belt.

"It is a group of asteroids which have similar orbits because they were fragments created during a collision between two asteroids," said astronomer Miroslav Brož of Charles University in Prague, lead author of two of the studies, published in the journal Nature, and Astronomy and Astrophysics.

Collisions in the main asteroid belt send rocky fragments flying haphazardly through space, with some of those eventually striking Earth.

"While more than 70,000 meteorites are known, only 6% had been clearly identified by their composition as coming from the moon, Mars, or Vesta, one of the largest asteroids in the main asteroid belt. The source of the other meteorites had remained unidentified," said astronomer Michaël Marsset of the European Southern Observatory in Chile, lead author of one of the two studies published in the journal Nature.

The Massalia asteroid family, formed about 40 million years ago, accounts for a class of meteorites called L chondrites that represent 37% of known Earth meteorites, the research found. The Karin family, formed 5.8 million years ago, and the Koronis family, formed 7.6 million years ago, account for a class of meteorites called H chondrites that represent 33% of known Earth meteorites, it showed.

Another 8% of the Earth meteorites can be traced to the Flora and Nysa asteroid families in the main asteroid belt, the research found. And about 6% of the meteorites can be traced to Vesta, it showed. Previous research found that less than 1% of the meteorites came from Mars and the moon.

The researchers are still exploring the source of the remaining roughly 15% of known Earth meteorites.

Space rocks have played a role in shaping the direction of life on Earth.

The new research did not look at the source of the one that struck Earth 66 million years ago that wiped out the dinosaurs, aside from their bird descendants, and enabled mammals to become dominant. Another study published in August found that this object formed beyond Jupiter and probably migrated inward to become part of the main asteroid belt before being sent hurtling toward Earth, perhaps due to a collision.

As the dinosaur-killing impact showed, a large space rock can pose a mortal threat to life on Earth. In 2022, NASA's DART spacecraft slammed into the asteroid Dimorphos in a proof-of-principle planetary defense mission that showed that a spacecraft can change a celestial object's trajectory just enough to keep Earth safe.

Some of the meteorites that have landed on Earth can give clues about the solar system's early history. They are primordial leftovers from a time before the planets formed in a large disk of material - called the protoplanetary disk - swirling around the newborn sun.

"Chondrites are primitive meteorites that have mostly preserved their original composition since their formation in our protoplanetary disk," Marsset said.
