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.


Alien Planet starts out with an interstellar spacecraft named Von Braun , leaving Earth's orbit. Traveling at 20% the speed of light (37,000 miles/s), 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 (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 (2.4 m) high, 40-foot (12 m) 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. 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. It tries to communicate with one, but a sonic ping interrupts the conversation and scares off the animal, and he is knocked out by a mysterious creature. Ike ventures to the meadows and gullies of Darwin IV, encountering massive Grovebacks and a herd of Littoralopes. Flying above are dangerous predators: the Skewers.

Leo briefly re-establishes contact with Von Braun, but soon gets destroyed by a mysterious and evasive creature, and Ike is ordered by the mothership to search for Leo and his attacker. Ike's route takes him over perilous terrain, and across the Amoebic Sea. As he embarks on his journey, one of the Grovebacks seen earlier falls victim to a swarm of Beach Quills. Ike then finds a pack of Prongheads hunting a Gyrosprinter, and crosses the Amoebic Sea (which attempts to attack him), encountering a herd of giant Sea Striders.

Ike manages to find Leo after a harrowing experience with a Skewer which tries to attack him, but is killed by a spear thrown by the newly discovered floating Eosapien. Shortly afterward, Ike communicates with the Eosapien tribe and discovers that they are truly intelligent. 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 an attack and destroys the camera disk. 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.


Alien Planet is based on Expedition (1990) by the American artist and writer Wayne Barlowe, a heavily illustrated book which aimed to explore and describe a fictional extraterrestrial ecosystem as if it was as real as that of Earth. [1] Barlowe served as one of the executive producers of the adaptation. [1] For the TV version, a broad team of scientists, and other figures, were assembled to comment on the life on Darwin IV, or to make general statements on life on Earth or out in the universe. Some of the people featured include physicists Michio Kaku and Stephen Hawking, paleontologist Jack Horner, NASA chief scientist James B. Garvin and director, screenwriter and producer George Lucas. [1] Though the documentary gives the appearance of the featured scientists having designed Darwin IV and its animals, [2] most of what is shown of the actual planet and its life follows what is described in Expedition. [1]

Though much of Darwin IV and its creatures is identical to what was presented in the book, Alien Planet diverges from Expedition in several ways. Unlike Expedition, which is set in the mid-24th century, Alien Planet is set at an unspecified point in the near future, and unlike in the book, when the expedition was a crewed mission, the planet is explored using sophisticated probes. [1] The technology featured is more advanced than present-day technology, but is based on current trends and informed speculation. Technologies such as autonomous probes and controlled 'miniprobes' are similar to technologies proposed by, or under development, by modern militaries and space agencies. [1]


Writing in The Space Review, the space historian Dwayne A. Day gave the special a positive review and concluded that "the writers and producers of Alien Planet have managed to successfully transcend current definitions of biology and yet still remained within the realm of the possible". [1]

As also happened with the 1990 book, some criticism was leveled by reviewers at the strangeness of the creatures showcased in Alien Planet. In his review of the TV special, Dwayne A. Day stated that "the animals are bizarre and frequently border on the implausible" and that "they do not appear to have been developed with a single biological theory in mind". Day also noted, concerning the scientists who talk about the animals as if they were real, "clearly some of them think that the animals that they are supposed to report about are barely plausible". However, Day also stated that the Darwinian creatures are thought-provoking and that their strangeness is a good departure from the typical science fiction approach of making alien life look much like Earth life (such as using humanoid aliens). According to Day, the life of Darwin IV "makes the point that alien life, if it is detected, will challenge our abilities to understand and even comprehend it". [1] A review in TheWashington Post stated that "a few too many of the creatures seem like cartoonish monsters", though stated "but around almost every corner one encounters some sort of nutritious food for thought".

Astrobiology Science concerned with life in the universe

Astrobiology, formerly known as exobiology, is an interdisciplinary scientific field that studies the origins, early evolution, distribution, and future of life in the universe. Astrobiology considers the question of whether extraterrestrial life exists, and if it does, how humans can detect it.

The Fermi paradox is the conflict between the lack of clear, obvious evidence for extraterrestrial life and various high estimates for their existence.

Space exploration Discovery and exploration of outer space

Space exploration is the use of astronomy and space technology to explore outer space. While the exploration of space is carried out mainly by astronomers with telescopes, its physical exploration though is conducted both by uncrewed robotic space probes and human spaceflight. Space exploration, like its classical form astronomy, is one of the main sources for space science.

The idea of self-replicating spacecraft has been applied – in theory – to several distinct "tasks". The particular variant of this idea applied to the idea of space exploration is known as a von Neumann probe after mathematician John von Neumann, who originally conceived of them. Other variants include the Berserker and an automated terraforming seeder ship.

Extraterrestrial hypothesis Hypothesis that some unidentified flying objects are occupied by extraterrestrial life

The extraterrestrial hypothesis (ETH) proposes that some unidentified flying objects (UFOs) are best explained as being physical spacecraft occupied by extraterrestrial life or non-human aliens, or non-occupied alien probes from other planets visiting Earth.

Xenoarchaeology, a branch of xenology dealing with extraterrestrial cultures, is a hypothetical form of archaeology that exists mainly in works of science fiction. The field is concerned with the study of the material remains to reconstruct and interpret past life-ways of alien civilizations. Xenoarchaeology is not currently practiced by mainstream archaeologists due to the current lack of any material for the discipline to study.

The cultural impact of extraterrestrial contact is the corpus of changes to terrestrial science, technology, religion, politics, and ecosystems resulting from contact with an extraterrestrial civilization. This concept is closely related to the search for extraterrestrial intelligence (SETI), which attempts to locate intelligent life as opposed to analyzing the implications of contact with that life.

Speculative evolution Science fiction genre exploring hypothetical scenarios in the evolution of life

Speculative evolution is a genre of speculative fiction and an artistic movement focused on hypothetical scenarios in the evolution of life, and a significant form of fictional biology. It is also known as speculative biology and it is referred to as speculative zoology in regards to hypothetical animals. Works incorporating speculative evolution may have entirely conceptual species that evolve on a planet other than Earth, or they may be an alternate history focused on an alternate evolution of terrestrial life. Speculative evolution is often considered hard science fiction because of its strong connection to and basis in science, particularly biology.

Breakthrough Initiatives is a science-based program founded in 2015 and funded by Julia and Yuri Milner, also of Breakthrough Prize, to search for extraterrestrial intelligence over a span of at least 10 years. The program is divided into multiple projects. Breakthrough Listen will comprise an effort to search over 1,000,000 stars for artificial radio or laser signals. A parallel project called Breakthrough Message is an effort to create a message "representative of humanity and planet Earth". The project Breakthrough Starshot, co-founded with Mark Zuckerberg, aims to send a swarm of probes to the nearest star at about 20% the speed of light. The project Breakthrough Watch aims to identify and characterize Earth-sized, rocky planets around Alpha Centauri and other stars within 20 light years of Earth. Breakthrough plans to send a mission to Saturn's moon Enceladus, in search for life in its warm ocean, and in 2018 signed a partnership agreement with NASA for the project.

Snaiad Speculative evolution project

Snaiad is a speculative evolution, science fiction and artistic worldbuilding project by Turkish artist C. M. Kosemen, focused on a fictional exoplanet of the same name. Begun in the early 2000s and inspired by earlier works such as Wayne Barlowe's 1990 book Expedition, Kosemen has produced hundreds of paintings and sketches of creatures of Snaiad, with detailed ecological roles and taxonomic relationships to each other. The sheer number of invented creatures and lineages makes Snaiad one of the most biologically diverse fictional worlds.
