After three and a half years on Mars, NASA’s InSight lander is nearing the end of its operations. Martian dust has coated the spacecraft’s two solar panels to the point that they will soon not be able to generate enough power to run InSight’s instruments. You can see just how much Martian dust has accumulated in this comparison of a photo taken in December 2018 (left) and another taken in June 2021 (right). NASA expects that InSight’s operations will end in July unless strong winds blow enough dust off the solar panels. Image credit: NASA/JPL-Caltech.
Martian dust storms are serious business. InSight was hit by a dust storm nearly twice the size of the United States in January 2022. A dust storm that obscured the entire planet caused the end of NASA’s Opportunity mission in 2018.
Listened to a NASA guy last night. He said put a single grain of sand on your fingertip and hold it out at arms length. At that distance the grain of sand would completely hide the piece of sky that pic was taken of. That just completely blows my mind.
Our brains are just not evolved to visualise the scope and scale of the cosmic reality we are a part of.
But having said that, the thing that amazes me more than anything else is that evolution driven by physical and chemical processes has produced not just life but consciousness. Awareness. The thing that makes our intelligence different from a machine.
