Dark Sand Cascades on #Mars
Dark streaks on Martian dunes, mistaken for trees, are actually cascades of sand revealed by melting frost. Captured by the Mars Reconnaissance Orbiter in 2008 near Mars' North Pole, these features form as CO2 ice thaws in spring, causing sand to slide down dunes.

It is really time for Ukraine to respond with 'like for like'. If Russia attacks civilian infrastructure/buildings, Ukraine must do the same to Moscow. Focus needs to be on Moscow as that is where the Russian barbarian action is organized. Ukraine's 'excuse' of being accused of targeting civilians is just a cop-out. Easily countered with the 'excuse' that it is only a response to Russian action first. Moscow people need to feel the same pain as Ukrainian people. That may result in a change of approach, or even leadership.
Слава Україні 🇺🇦
