This young girl named the robots: Spirit Opportunity Size of a golf cart
She was born in Russia and adopted by an American family when she was two years old.
This is what she wrote that won a contest she had entered.
I used to live in an orphanage. It was cold, dark & lonely. At night, I looked up at the sky to feel better. I dreamed I could fly there. In America, I can make all my dreams come true. Thank-you for the 'Spirit' and the 'Opportunity'
