Dust devil…on Mars

NASA’s Curiosity Mars rover spotted this dust devil with one of its Navigation Cameras on Aug. 9, 2020…Taken from the “Mary Anning” drill site, this dust devil appears to be passing through small hills just above Curiosity’s present location on Mount Sharp. The dust devil is approximately one-third to a half-mile away and estimated to be about 16 feet wide. The dust plume disappears past the top of the frame, so an exact height can’t be known, but it’s estimated to be at least 164 feet tall.

As we explore this tiny corner of our solar system, sometimes we discover new, sometimes we find same or similar. As someone with a basic understanding of what should be high school-level science…would know.

    “Buried lakes of liquid water discovered on Mars” (BBC News 9/29/20) https://www.bbc.com/news/science-environment-54337779
    “Three underground lakes have been detected near the south pole of Mars.
    Scientists also confirmed the existence of a fourth lake – the presence of which was hinted at in 2018.
    Liquid water is vital for biology, so the finding will be of interest to researchers studying the potential for life elsewhere in the Solar System.
    But the lakes are also thought to be extremely salty, which could make it difficult for any microbial life to survive in them.
    Mars’ thin atmosphere means that the presence of liquid water on the surface is a near-impossibility. But water could remain liquid below ground.
    The latest discovery was made using data from a radar instrument on the European Space Agency’s (Esa) Mars Express spacecraft, which has been orbiting the Red Planet since December 2003.”

    The main lake (centre) is surrounded by at least three smaller bodies of water
