Greetings Martians! I'm just up here on the Red Planet, roving, taking a low-angle selfie to send home showing my investigation of the "Buckskin" rock target, where I collected my seventh drilled sample. It's been a great three years at work! My job as an explorer, conducting science and technology research, is really paying off. With love, - NASA’s Curiosity Mars Rover Happy #MarsMonday, everybody!
