Ejections or Impacts

  • Marsprobe5 by Marsprobe5

    I'm beginning to think that these types of images are a type of impact that are not the type that create creators.
    I was thinking at first they might be vapour/gasses ejections/eruptions. ....?

    They are definitely not impacts, they are too regularly repeating each spring over same small areas - impossible to target so well any natural projectiles.

    In this image there is something else that makes me pose each time: the tiny blue fans in the middle of dark fans. Totally not usual - blue fans are normally around the dark fan. These are more rare and I have a gut feeling that they are only very early spring features. So, I'd like you (and anybody else) to #-tag them with #central_blue_fans - I'd really like to see the stats on these guys.
