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 .

Of all the features with Which the probes are equipped, Which is primarily for communication with alien life forms?

Halting just outside the village, Harry formed his men with a front across the whole road, and directed the lines to advance, twenty yards apart. Then, placing himself at their head, he gave the word, and charged down the street upon the Roundheads. The latter, occupied by their attack upon the houses, were unconscious of the presence of their foe until he was close upon them, and were taken utterly by surprise. The force of the charge was irresistible, and the Roundheads, dispersed and on foot, were cut down in all directions. Groups of twos and threes stood together and attempted resistance, but the main body thought only of regaining their horses. In three minutes after the Royalists entered the village the surviving Roundheads were in full flight, hotly pursued by the victorious Cavaliers. These, being for the most part better mounted, overtook and slew many of the Roundheads, and not more than half the force which had set out returned to their quarters at Didcot. The pursuit continued to within half a mile of that place, and then Harry, knowing that there was a force of Roundhead infantry there, drew off from the pursuit, and returned to Chalcombe. He found that more than half of Sir Ralph Willoughy's men had been killed, many having been cut down before they could betake themselves to their arms, those quartered in the inn, and at two or three of the larger houses, having alone maintained a successful resistance until the arrival of succor.

Was Chalcombe a town, village, or city?

(CNN) -- Guatemala's government has declared a state of siege and sent hundreds of troops to a northern province where officials say a Mexican drug gang is overtaking towns and threatening residents. President Alvaro Colom announced the 30-day emergency rule in Alta Verapaz on Sunday. The rule allows the military to order anyone suspected of conspiring against the government to be arrested and imprisoned without a warrant, the state-run AGN news agency said. "Starting today, combined forces will retake the streets of Alta Verapaz," a government statement released Sunday morning said. Government data shows cells of the drug gang known as Los Zetas are in the area to protect drug trafficking paths between Honduras and Mexico, "intimidating the population with their heavy weapons and threatening farmers to give up their land for criminal activities," AGN reported. The state of siege also allows the government to place greater restrictions on public gatherings, travel visas and gun licenses, among other things, according to AGN. "The population should be calm. What we are doing is not intended to persecute honest, working people," Interior Minister Carlos Menocal told reporters. Menocal said operations in the coming days would aim to boost regional security, regain control of territory, identify criminal gangs and capture their members. In an interview with CNN en Espanol last month, Menocal said his country needed more help from the United States to combat cartels, which were increasingly carving out new drug transport paths. "In the end, the large majority of drugs travel through Central America, and the assignment of resources or the financial support of the United States government is not the same as Colombia and Mexico receive," he said. Menocal said clashes between authorities and Los Zetas had notably increased.
