Incredible Journey of Pristine Meteorite Reveals Survival Secrets
Los Angeles CA (SPX) Apr 01, 2025 In April 2019, an unusual meteorite fall near Aguas Zarcas in northern Costa Rica offered scientists a rare look at a well-preserved, water-rich space rock. Researchers have since analyzed the event in detail, publishing their findings in Meteoritics and Planetary Science, and shown that despite their nickname, "mudball" meteorites can be remarkably durable. "27 kilos of rocks were recovered, making this the largest fall of its kind since similar meteorites fell near Murchison in Australia in 1969 ... read more
