For anyone who’s ever wanted a souvenir from Mars without the hassles of traveling there, here’s their chance. A Lincoln company is auctioning off part of the famous Mars meteorite Zagami, which fell to Earth Oct. 3, 1962, in central Nigeria. Bids for the fragment, which weighs about 6.6 ounces and is about the size of a soda can, begin at $450,000 when the online auction starts Sept. 5 on the Internet site eBay.
