Story summary

The European Space Agency (ESA) released an image of dark streaks on Mars linked to a meteoroid impact on Apollinaris Mons during 2013–2017.
Valentin Bickel of the University of Bern analyzed over two million streaks, concluding that most arise from seasonal wind and dust.
Only about one in a thousand streaks results from meteoroid impacts.
The findings stress dust dynamics for future Mars exploration, and ESA scientists call for observations.
