Marvelous Mars meteorites
Less than 1 percent of meteorites found on Earth come from Mars. About 60 have been found. These rare rocks tell us what the Red Planet was like billion of years ago.
A sample from the Tissint meteorite, which dropped from the sky in Morocco at 2 a.m. local time on July 18, 2011. Several large and small chunks of the meteorite fell in a shower that morning, giving scientists plenty of material to study from the 600-million-year-old rock, according to NASA.
This fragment of the Tissint meteorite, which fell in Morocco in 2011, was auctioned off for $43,750. The 1.6-ounce (46-gram) rock, like others in the Tissint meteor shower, was likely ejected from Mars some 1.1 million years ago, scientists estimate.
This infamous rock from Mars sparked years of controversy when researchers said the 3.9-billion-year-old rock held signs of life. Others say there's no evidence for biological activity in the meteorite.
