The world's first wooden satellite has blasted off on a SpaceX rocket, its Japanese developers said Tuesday, part of a resupply mission to the International Space Station.
Scientists at Kyoto University expect the wooden material to burn up when the device re-enters the atmosphere -- potentially providing a way to avoid generating metal particles when a retired satellite returns to Earth, AFP reported.
These particles may negatively impact both the environment and telecommunications, the developers say.
Each side of the box-like experimental satellite, named LignoSat, measures just 10 centimeters (four inches).
It was launched on an unmanned rocket from NASA's Kennedy Space Center in Florida, Kyoto University's Human Spaceology Center said.
The satellite, installed in a special container prepared by the Japan Aerospace Exploration Agency, "flew into space safely", it said in a post on X.
A spokeswoman for LignoSat's co-developer Sumitomo Forestry told AFP the launch had been "successful".
It "will arrive at the ISS soon, and will be released to outer space about a month later" to test its strength and durability, she said.
Data will be sent from the satellite to researchers who can check for signs of strain and determine if the satellite can withstand extreme changes in temperature.
"Satellites that are not made of metal should become mainstream," Takao Doi, an astronaut and special professor at Kyoto University, said at a press conference earlier this year.

Prince William went on an early-morning nature walk near South Africa's Table Mountain on Tuesday to promote the work of conservation rangers in a unique urban national park.

The Prince of Wales and heir to the British throne met with some of the rangers who guard the Table Mountain National Park, an 85-square-mile (220-square kilometer) area that overlooks Cape Town and spills into the city's suburbs in some areas.

William didn't go to the top of the famous flat-topped mountain, instead strolling through nature trails on Signal Hill, a foothill that sits by the ocean's edge.

The prince was accompanied on the walk by Megan Taplin, the park manager, and Robert Irwin, an Australian conservationist. William met with rangers, park firefighters and members of a K-9 dog unit.

“He got to learn about what they do on a daily basis and what challenges they face,” Taplin said. “We also spoke a lot about ranger wellness and how that's really important that rangers are supported, that their families are supported, because they are doing quite dangerous work and difficult work.”

William is in South Africa to promote his annual Earthshot Prize, which awards $1.2 million in grants to five entrepreneurs or organizations for innovative ideas that help the environment and combat climate change. William set up the Earthshot Prize in 2020 through his Royal Foundation and the awards ceremony will be held in Cape Town — the first time it's been in Africa — on Wednesday night.

The prince's four-day visit is a kind of environmental roadshow and is heavily focused on climate and conservation, though he did break away from those issues on his first day in Cape Town on Monday to attend a rugby practice at a local high school and play a little of South Africa's favorite sport with some of the kids.

William was also due to meet with South African President Cyril Ramaphosa at the president's Cape Town residence on Tuesday.

William has a range of engagements planned in South Africa's second-biggest city, including meetings with young environmentalists, attending a wildlife summit, visiting a botanical garden and spending time at a sea rescue institute and with a Cape Town fishing community.

William last visited Africa in 2018 but he has a strong connection to the continent. He traveled there as a boy after the death of his mother, Princess Diana, in a Paris car crash in 1997. He and his wife, Kate, got engaged at a wildlife conservancy in Kenya in 2010. And he said he came up with the idea for the Earthshot awards while in Namibia in 2018.

Before the visit, William said that Africa has always had “a special place in my heart.” William's brother Prince Harry visited South Africa and neighboring Lesotho last month for a charity he set up in southern Africa.

William's wife Kate, the Princess of Wales, and their children Prince George, Princess Charlotte and Prince Louis did not travel to South Africa. Kate only recently returned to some public duties after completing treatment for an undisclosed type of cancer.
