Which is why it still boggles my mind that they didn’t add a brush tool to clean off the solar panels on insight lander. They were literally willing to drop rocks on the panels durring the mission, but adding a 5$ brush to the arm thats already on the billion dollar martian lander, apparently thats not an option.
