University researchers find ballpoint pen ink contaminating Martian meteorites during lab preparation
Scientists from the University of the Basque Country found traces of ballpoint pen ink in six samples of Martian meteorites processed between 2001 and 2014, revealing contamination introduced during laboratory preparation rather than extraterrestrial origin. The discovery, published in Applied Geochemistry, underscores a persistent challenge in planetary science: despite rigorous cleaning protocols, terrestrial materials like … Read more
