The world's first wooden satellite has been built by Japanese researchers who said their tiny cuboid craft will be blasted off on a SpaceX rocket in September.

Each side of the experimental satellite developed by scientists at Kyoto University and logging company Sumitomo Forestry measures just 10 centimeters (four inches).

The creators expect the wooden material will burn up completely when the device re-enters the atmosphere -- potentially providing a way to avoid the generation of metal particles when a retired satellite returns to Earth.

These metal particles could have a negative impact on the environment and telecommunications, the developers said as they announced the satellite's completion on Tuesday.

"Satellites that are not made of metal should become mainstream," Takao Doi, an astronaut and special professor at Kyoto University, told a press conference.

The developers plan to hand the satellite, made from magnolia wood and named LignoSat, to space agency JAXA next week.

It will be sent into space on a SpaceX rocket from the Kennedy Space Center in September, bound for the International Space Station (ISS), they said.

From there, the satellite will be released from the Japanese ISS experiment module to test its strength and durability.

"Data will be sent from the satellite to researchers who can check for signs of strain and whether the satellite can withstand huge changes in temperature," a Sumitomo Forestry spokeswoman told AFP on Wednesday.

Also on Tuesday, a rocket carrying a separate sophisticated satellite -- a collaboration between the European Space Agency (ESA) and JAXA -- blasted off from California on a mission to investigate what role clouds could play in the fight against climate change.

The EarthCARE satellite will orbit nearly 400 kilometers (250 miles) above Earth for three years.

Greece's 'Instagram Island' Santorini nears Saturation Point

One of the most enduring images of Greece's summer travel brand is the world-famous sunset on Santorini Island, framed by sea-blue church domes on a jagged cliff high above a volcanic caldera.
This scene has inspired millions of fridge magnets, posters, and souvenirs -- and now the queue to reach the viewing spot in the clifftop village of Oia can take more than 20 minutes, said AFP.
Santorini is a key stopover of the Greek cruise experience. But with parts of the island nearing saturation, officials are considering restrictions.
Of the record 32.7 million people who visited Greece last year, around 3.4 million, or one in 10, went to the island of just 15,500 residents.
"We need to set limits if we don't want to sink under overtourism," Santorini mayor Nikos Zorzos told AFP.
"There must not be a single extra bed... whether in the large hotels or Airbnb rentals."
As the sun set behind the horizon in Oia, thousands raised their phones to the sky to capture the moment, followed by scattered applause.
For canny entrepreneurs, the Cycladic island's famous sunset can be a cash cow.
One company advertised more than 50 "flying dresses", which have long flowing trains, for up to 370 euros ($401), on posters around Oia for anyone who wishes to "feel like a Greek goddess" or spruce up selfies.
'Respect Oia'
But elsewhere in Oia's narrow streets, residents have put up signs urging visitors to respect their home.
"RESPECT... It's your holiday... but it's our home," read a purple sign from the Save Oia group.
Shaped by a volcanic eruption 3,600 years ago, Santorini's landscape is "unique", the mayor said, and "should not be harmed by new infrastructure".
Around a fifth of the island is currently occupied by buildings.
At the edge of the cliff, a myriad of swimming pools and jacuzzis highlight Santorini is also a pricey destination.
In 2023, 800 cruise ships brought some 1.3 million passengers, according to the Hellenic Ports Association.
Cruise ships "do a lot of harm to the island", said Chantal Metakides, a Belgian resident of Santorini for 26 years.
"When there are eight or nine ships pumping out smoke, you can see the layer of pollution in the caldera," she said.
Cruise ship limits
In June, Prime Minister Kyriakos Mitsotakis floated the possibility of capping cruise ship arrivals to Greece's most popular islands.
"I think we'll do it next year," he told Bloomberg, noting that Santorini and tourist magnet Mykonos "are clearly suffering".
"There are people spending a lot of money to be on Santorini and they don’t want the island to be swamped," said the pro-business conservative leader, who was re-elected to a second four-year term last year.
In an AFP interview, Tourism Minister Olga Kefalogianni echoed this sentiment and said: "We must set quotas because it's impossible for an island such as Santorini... to have five cruise ships arriving at the same time."
Local officials have set a limit of 8,000 cruise boat passengers per day from next year.
But not all local operators agree.
Antonis Pagonis, head of Santorini's hoteliers association, believes better visitor flow management is part of the solution.
"It is not possible to have (on) a Monday, for example, 20 to 25,000 guests from the cruise ships, and the next day zero," he said.
Pagonis also argued that most of the congestion only affects parts of the island like the capital, Fira.
In the south of the island, the volcanic sand beaches are less crowded, even though it is high season in July.
'I'm in Türkiye
The modern tourism industry has also changed visitor behavior.
"I listened (to) people making a FaceTime call with the family, saying 'I'm in Türkiye," smiled tourist guide Kostas Sakavaras.
"They think that the church over there is a mosque because yesterday they were in Türkiye."
The veteran guide said the average tourist coming to the island has changed.
"Instagram has defined the way people choose the places to visit," he said, explaining everybody wants the perfect Instagram photo to confirm their expectations.
