... mulled over this over, no doubt in conversations with Apollo rock guys, connecting the dots and planning his colorful adventure ... Bob's 1989 catalog listed Zagami as possibly of Martian origin, where his Nakhla was "probably" of Martian origin reflecting the claim of the moment.

I'd say the Mars meteorite story really started with Nakhla in the early 1970s, and that was before Viking, when Apollo guys started getting restless for something new and exciting after learning so much about moon rocks. By then, the view of SNCs being separate from HEDs took hold. I'm guessing guys like Ted Bunch were a little cautious about claiming Mars at the time, but Noboru Nakamura is on record in 1977 as not shy to suggest Mars as the parent body after studying rare earth element compositions. By 1982 this was complemented by the Viking atmospheric data and analyses from what I gather, that were proposed over a dinner in a Mexican restaurant with a sample of Nakhla a Harvard researcher's wife twisted her husband to provide and the rest is history. Perhaps someone else has a more accurate story, but I believe Zagami was the second meteorite to have its glassy sealed gas composition determined - not sure. Between 1983 and 1988 Bob Haag would have mulled over this over, n

Did they have an idea it was from Mars at the time....? It was later when the Viking Lander sent back info that they decided SNCs were most likely from Mars...that would be when the excitement started.

Based on the theories of the likes of McEwen and Melosh, about 2,800,000 years ago, possibly over 500 billion (500x10^9) kilos of Mars escaped the Red Planet, only a small fraction from an impact that left a 10 km primary crater, and 10 million more craters on Mars over 33 feet in diameter each. Fast forward to 1962 as an African man chasing cows away was nearly hit by an 18 kg mass of this material that survived until it plopped into his cornfield. There, the legend was brought into the realm of excited meteorite collectors around the world ... Thanks Tomasz for sharing a handsome piece of the evidence, which still had some of the Martian atmosphere sealed inside it for researchers to observe ...
