The article certainly captures readers' attention with a clickbaity headline, but ultimately the article was very straightforward, provided great context, and left me with a new understanding of what it's like for the rover team to process the images it's seeing and how it has to account for materials that it is responsible for dropping on the red planet.

Misleading headline that leads the reader into believing it's something alien or extraterrestrial, knowingly so, for clicks, when it's already been confirmed to have been debris from previous missions.
