The moon is about to get walloped by 3 tons of space junk, a punch that will carve out a crater that could fit several semitractor-trailers.

The leftover rocket will smash into the far side of the moon at 5,800 mph (9,300 kph) on Friday, away from telescopes' prying eyes. It may take weeks, even months, to confirm the impact through satellite images.

The Apollo 16 capsule is dusty all these decades after it carried three astronauts to the moon. Cobwebs cling to the spacecraft. Business cards, a pencil, money, a spoon and even a tube of lip balm litter the floor of the giant case that protects the space antique in a museum.

The COVID-19 pandemic meant a break in the normal routine of cleaning the ship's display at the U.S. Space and Rocket Center, located near NASA's Marshall Space Flight Center. But workers are sprucing up the spacecraft for the 50th anniversary of its April 1972 flight.

Toyota is working with Japan's space agency on a vehicle to explore the lunar surface, with ambitions to help people live on the moon by 2040 and then go live on Mars, company officials said Friday.

The vehicle being developed with the Japan Aerospace Exploration Agency is called Lunar Cruiser, whose name pays homage to the Toyota Land Cruiser sport utility vehicle. Its launch is set for the late 2020's.

Tonga's volcanic eruption felt like an "atomic bomb" that shook "the whole island", an aid worker told AFP on Friday, as the Pacific nation raced to address a drinking water shortage.

Researchers on Thursday reported the latest in a surprising string of experiments in the quest to save human lives with organs from genetically modified pigs.

This time around, surgeons in Alabama transplanted a pig's kidneys into a brain-dead man — a step-by-step rehearsal for an operation they hope to try in living patients possibly later this year.

The 19-year-old Belgian-British pilot Zara Rutherford set a world record as the youngest woman to fly solo around the world, touching her small airplane down in western Belgium on Thursday — 155 days after she departed.

Rutherford will find herself in the Guinness World Records book after setting the mark that had been held by 30-year-old American aviator Shaesta Waiz since 2017.

Albert Bourla, chairman and chief executive of global pharmaceutical giant Pfizer Inc., was awarded on Wednesday the prestigious Genesis Prize for his efforts in leading the development of a COVID-19 vaccine.

The $1 million award is granted each year to a person for their professional achievements, contributions to humanity and commitment to Jewish values. The Genesis Prize Foundation said Bourla had received the largest number of votes in an online campaign in which some 200,000 people in 71 countries participated.

Auction house Sotheby's Dubai has unveiled a diamond that's literally from out of this world.

Sotheby's calls the 555.55-carat black diamond — believed to have come from outer space — "The Enigma." The rare gem was shown off on Monday to journalists as part of a tour in Dubai and Los Angeles before it is due to be auctioned off in February in London.

A 4 billion-year-old meteorite from Mars that caused a splash here on Earth decades ago contains no evidence of ancient, primitive Martian life after all, scientists have reported.

In 1996, a NASA-led team announced that organic compounds in the rock appeared to have been left by living creatures. Other scientists were skeptical and researchers chipped away at that premise over the decades, most recently by a team led by the Carnegie Institution for Science's Andrew Steele.

In a medical first, doctors transplanted a pig heart into a patient in a last-ditch effort to save his life and a Maryland hospital said Monday that he's doing well three days after the highly experimental surgery.

While it's too soon to know if the operation really will work, it marks a step in the decades-long quest to one day use animal organs for life-saving transplants. Doctors at the University of Maryland Medical Center say the transplant showed that a heart from a genetically modified animal can function in the human body without immediate rejection.
