Adriana Ocampo grew up in Buenos Aires, Argentina, dreaming about exploring planets. She never doubted that all her dreams would come true someday. How did Adriana land a job with NASA, the U.S. space agency, while still in her teens? How did a robot parked on Mars make her fall in love with rocks and instantly decide to become a planetary geologist? Adriana's imagination and can-do attitude have led her to a life of science adventures. Adriana helped find the missing Crater of Doom, a hole blasted out of Earth by a killer space rock 65 million years ago, when the dinosaurs died out. Now she's searching the world for the stuff that came from that crater. Between rock digs she explores other planets through the electronic eyes of NASA's robotic spacecraft. How did an imaginative young girl with a dream of space exploration become a planetary geologist? Author Lorraine Jean Hopping makes the woman and her science come to life on every page, delighting readers of all ages.
