A new study of Apollo lunar rocks suggests that the moon is older than anyone believed.

The moon, researchers now say, likely formed about 50 million years after the solar system did, which is much earlier than the previous estimate of 150 million years after solar-system formation. A German-led group ferreted out the new estimate by studying three rare elements.

The traditional scientific origin story of the moon goes like this: The solar system arose about 4.56 billion years ago from a cloud of gas and dust in our cosmic neighborhood. Then, early in Earth's history, a Mars-size object careened into our planet. The invader got smashed to bits and took out a big chunk of our planet with it. This collision formed a huge debris cloud around Earth that over eons coalesced into our moon.

The newly theorized lunar age of 4.51 billion years, however, came after the team reanalyzed samples brought back by Apollo astronauts around 50 years ago. Such studies have happened many times before, but as instruments improve with advancing technology, it's possible for experts to make more-sensitive measurements of the rocks.

A sample collected during the Apollo 12 mission is predominantly ilmenite basalt and also includes glass created by an impact.

The scientists behind the new research zeroed in on the magma ocean that covered the moon shortly after the natural satellite formed; over time, this ocean cooled into the darker basalt regions still visible on the moon today. The researchers measured characteristics of three rare elements within this material: hafnium, uranium and tungsten.

3. Why did Neil and Buzz give Holland a fake "moon rock"?

UK Telegraph 29 AUG 2009

'Moon rock' given to Holland by Neil Armstrong and Buzz Aldrin is fake
A moon rock given to the Dutch prime minister by Apollo 11 astronauts in 1969 has turned out to be a fake



Curators at Amsterdam's Rijksmuseum, where the rock has attracted tens of thousands of visitors each year, discovered that the "lunar rock", valued at £308,000, was in fact petrified wood.

Xandra van Gelder, who oversaw the investigation, said the museum would continue to keep the stone as a curiosity.

"It's a good story, with some questions that are still unanswered," she said. "We can laugh about it."

The rock was given to Willem Drees, a former Dutch leader, during a global tour by Neil Armstrong, Michael Collins and Edwin "Buzz" Aldrin following their moon mission 50 years ago.

J. William Middendorf, the former American ambassador to the Netherlands, made the presentation to Mr Drees and the rock was then donated to the Rijksmuseum after his death in 1988.

"I do remember that Drees was very interested in the little piece of stone. But that it's not real, I don't know anything about that," Mr Middendorf said.

Nasa gave moon rocks to more than 100 countries following lunar missions in 1969 and the 1970s...more: https://www.telegraph.co.uk/news/science/space/6105902/Moon-rock-given-to-Holland-by-Neil-Armstrong-and-Buzz-Aldrin-is-fake.html

How could NASA have "lost" the original videos?

The Apollo 11 missing tapes were those that were recorded from Apollo 11's slow-scan television (SSTV) telecast in its raw format on telemetry data tape at the time of the first Moon landing in 1969 and subsequently lost. The data tapes were recorded as a backup in case the live television broadcasts failed for any reason.

A team of retired NASA employees and contractors tried to find the tapes in the early 2000s but was unable to do so. The search was sparked when several still photographs appeared in the late 1990s that showed the visually superior raw SSTV transmission on ground-station monitors. ... https://en.wikipedia.org/wiki/Apollo_11_missing_tapes
