Alien Planet starts out with an interstellar spacecraft named Von Braun , leaving Earth's orbit . Traveling at 20 % the speed of light , it reaches Darwin IV in 42 years . Upon reaching orbit , it deploys the Darwin Reconnaissance Orbiter , Which looks for potential landing sites for the probes . The first probe , Balboa , explodes along with its lifting body transport during entry , because one of its wings failed to unfold . Two backup probes , Leonardo da Vinci and Isaac Newton , successfully land on the planet , and learn much about its bizarre indigenous lifeforms , including an apparently sapient species . The robotic probes sent out to research on Darwin IV are called Horus Probes . Each Horus probe consists of an { { convert } } long inflatable , hydrogen-filled balloon , Which is covered with solar receptors , a computer ' brain ' , a ' head ' covered with sensors , and several smaller robots that can be sent to places too dangerous for the probes themselves . The probes have a limited degree of artificial intelligence , very similar to the ' processing power ' of a 4-year-old . All the real thinking is done by a supercomputer in the orbiting Von Braun . The probes are programmed with different personalities ; Ike is more cautious , while Leo is the risk-taker . The two probes are also equipped with a holographic message that will be projected to any sentient life found on Darwin . After the two probes inflate their gas-bags , they encounter a voracious Arrowtongue and watch it pursue a Gyrosprinter .

Balboa, Leonardo da Vinci, and Isaac Newton are all types of what?

Duane was hungry, but he hurried through the ample supper that was set before him, urged on by curiosity and astonishment. The only way he could account for his presence there in a ranger's camp was that MacNelly hoped to get useful information out of him. Still that would hardly have made this captain so eager. There was a mystery here, and Duane could scarcely wait for it to be solved. While eating he had bent keen eyes around him. After a first quiet scrutiny the rangers apparently paid no more attention to him. They were all veterans in service--Duane saw that--and rugged, powerful men of iron constitution. Despite the occasional joke and sally of the more youthful members, and a general conversation of camp-fire nature, Duane was not deceived about the fact that his advent had been an unusual and striking one, which had caused an undercurrent of conjecture and even consternation among them. These rangers were too well trained to appear openly curious about their captain's guest. If they had not deliberately attempted to be oblivious of his presence Duane would have concluded they thought him an ordinary visitor, somehow of use to MacNelly. As it was, Duane felt a suspense that must have been due to a hint of his identity.

Who were the rangers pretending to not paying attention to?

Boone, Ia. -Poor and elderly people may soon go without legal representation in Boone County. Boone County Legal Aid, which for 31 years has provided legal services to those who couldn't afford them, will close in February if a $10,000 grant from Prairie Meadows Racetrack and Casino is not awarded. The legal service is one of the few programs in Iowa that offers legal representation to those who qualify without turning to the state for its services. "It is a very sad situation, but that's the fact," said Alan Schroeder, city attorney and supervisor of Boone County Legal Aid. For the past two years using money mostly from the city and county, Schroeder has upheld the outfit alone, taking on about 60 clients a year, and settling cases that range from domestic abuse to bankruptcy. He also has a private practice. If the legal service closes, he's unsure where his clients will go. The city of Boone gave Schroeder $6,300 in July to resolve pending cases, said Kathy Berg, Boone's finance officer. Without that, the program might already be closed. "All governments are having problems with finances," Boone Mayor George Maybee said. "No one else stepped in. The county didn't. The state didn't." Donovan Olson, chairman of the county Board of Supervisors, said the board quit funding the legal service in July because it felt the county didn't need it. Drake University ended its funding after the 2000 spring semester "for a variety of reasons," Suzanne Levitt, the law professor who oversaw the program, said via e-mail. Olson said Schroeder must prove Prairie Meadows is the primary money source for the board to grant the program any more money. Schroeder ran the program without the help of law students or Drake, which had provided as much as two-thirds of the money in some years.
