Alien Planet is a 2005 docufiction TV special created for the Discovery Channel. Based on the 1990 book Expedition by the artist and writer Wayne Barlowe, Alien Planet explores the imagined extraterrestrial life of the fictional planet Darwin IV in the style of a nature documentary. Although closely following Barlowe's depiction of Darwin IV, Alien Planet features a team of scientists and science fiction figures discussing Darwin IV as if it had actually been discovered. Among the people featured are Michio Kaku, Stephen Hawking, Jack Horner, James B. Garvin and George Lucas. Alien Planet garnered positive reviews as a thought-provoking programme, though some criticism was raised concerning the strange creatures featured, which some reviewers saw as bordering on implausible.
== Plot == Alien Planet starts out with an unmanned interstellar spacecraft named Von Braun, leaving Earth's orbit. Traveling at 20% the speed of light (37,000 miles/s), it reaches Darwin IV, a planet 6.5 light-years away, 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 (nicknamed Leo) and Isaac Newton (nicknamed Ike), 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 8-foot-high (2.4 m), 40-foot-long (12 m) 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 four-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. Later that night, the twins find the wreckage of Balboa and are ordered to split up, Ike studying the unique plant life and Leo going after big game. Ike's voyage takes him to one of Darwin IV's pocket forests, where he encounters a flock of Trunk Suckers and their predator, the Daggerwrist. Before his research is finished, a massive hurricane-like storm hits and Ike must take to the sky, launching weather balloons. Leo goes to the mountain ranges and finds a herd of Unths engaged in rutting-like behavior. Afterward, Leo finds a pair of Bladderhorns engaging in combat, and tries to present the holographic message to one, but a sonic ping interrupts the conversation and scares off the animal before the probe is suddenly knocked out. Ike ventures to the meadows and gullies of Darwin IV, encountering massive Grovebacks, a herd of Littoralopes, the dangerous airborne predatory Skewers, a Groveback falling victim to a swarm of Beach Quills, and a pack of Prongheads hunting a Gyrosprinter. Leo briefly re-establishes contact with Von Braun until a mysterious and evasive creature suddenly interferes, and Ike is ordered by the mothership to search for Leo. Ike's route takes him over perilous terrain, including the planet’s only sea, and find the entire aforementioned sea is Amoebic in nature (and attempts to attack him), making it a source of food to giant Sea Striders. Ike manages to find Leo’s last known location, where a Skewer tries to attack him, but is killed by a spear. Investigating, Ike finds Leo and the mysterious, evasive and sapient species that has been trailing the two probes, the floating Eosapiens. Ike presents the holographic message to the Eosapien tribe and discovers they are truly intelligent, at a level estimated to be comparable to early humans. Ike launches a camera disk to record the moment, or perhaps "to assess the threat" due to a third Eosapien appearing; however one of the Eosapiens mistakes it as a deliberate attack, and destroys the camera disk while the others are prompted to directly attack Ike. Before shutting down, the wrecked camera disk records the Eosapien tribe carrying Ike away. Commentary from notable people discussing the details behind the fictional world of Darwin IV and the likelihood of extraterrestrial life, in general, is interspersed throughout the special.
