NASA's Perseverance rover on Mars captured this image of a cylindrical metallic object on the planet's surface. The object is most definitely a drill bit. How do we know for sure? Because Perseverance dropped it. (Or that's what They want us to believe, anyway.)
Last year, @NASAPersevere Twitter account tweeted a photo of the drill bit in place, commenting:
"This particular drill bit was installed before launch, to close out the drill and keep the inside protected. To keep my science clean and clear, I'm leaving it aside before I start to collect samples with new, pristine drill bits."
