ALH84001

Historic meteorites in the 20th century? Sure. They may not be historic in terms of their age, but many have booked a place in the history books.

The Nakhla impact (Egypt, *1911), for instance. Not only was it alleged to have struck and killed a dog, it was subsequently discovered that it originated from an impact on the planet Mars. Indeed, a whole class of meteorites (Nahklites) are named after it.

Allende (Mexico, *1969) is still by far the largest recorded fall of carbonaceous material. It was used as test specimens for the NASA moon rock receiving labs.

ALH84001 – the “proof” of life on Mars, was recovered in Antarctica in 1984. Some ten years later, researchers claimed they had found evidence of fossilised Martian microbes trapped in the meteorite. The jury is still out.
