Today in class we read a book called “The Adventures of Sojourner”. It was about one of the pathfinders that they sent to Mars. It successfully landed on Mars without harm. It’s APXS  tested on these rocks called Yogi, Barnacle Bill, Soufflé, Scooby Doo, and Shark. On Sol 30 Sojourner set out for a Rock Garden. It was Sojourner next assignment to reach a rock called Shark. It would be Sojourner’s toughest assignments. Sojourner reach Shark on Sol 52. But six days later Sojourner’s backup battery ran out. The team on Earth tried to signal her, but no response came back. On October 1 the team got a signal from the rover, and on October 7 they only got one final signal and that was it. The team keeps on trying to signal the rover once every month, but no luck. The mission had cost about 266 million. Sojourner returned 2.3 million bits of information and more than 16,500 lander images.
