Intanto, i membri della Toy Box 2 si imbattono in una mina spaziale degli USA e Fee si lancia in azioni anti-governative per opporsi alla guerra spaziale in procinto di scoppiare.
Nonostante il rifiuto di Fee, il colonnello Thunders la erge ad eroina del movimento pacifista.
Il capitano della Von Braun incarica Hachi di pronunciare il discorso di sbarco su Giove. Locksmith fa visita ad un prete, suo professore di ingegneria, per reclutarlo come scienziato per una missione su Saturno, ma quest'ultimo rifiuta.
Nel giugno Sunrise e Bandai Visual iniziarono a discutere di una possibile coproduzione animata di genere fantascientifico. I produttori della serie TV decisero dunque di modificare in parte la vicenda, facendo apparire Tanabe come protagonista sin dal primo episodio della serie per poi plasmare i successivi episodi sulla sua esperienza nello spazio e sulla missione di Hachimaki a bordo della Von Braun; gli eventi conclusivi della serie hanno a loro volta uno svolgimento differente da quelli presenti nel manga.
Parte dello staff di produzione dell'anime ha partecipato anche alla produzione di un'altra serie, che venne trasmessa nello stesso periodo dal network NHK , Twin Spica.
Per questa ragione, si trovano alcuni velati riferimenti a quest'ultima serie all'interno di Planetes, come ad esempio:. Seppur differenti nello sviluppo della trama principale, delle sottotrame e in parte del cast di personaggi, l'anime e il manga presentano numerosi riferimenti reciproci, tra i quali:.
Nell'anime non mancano i riferimenti alla tecnologia odierna, o ad oggi considerata futuribile ma realizzabile negli anni a venire, per esempio:. Altri progetti.

The absence of evidence of lava flow accompanying any of the visible calderas remains an enigma. These features are volcanic in origin.
Most Venusian surface features are named after historical and mythological women. The last three features were named before the current system was adopted by the International Astronomical Union , the body which oversees planetary nomenclature.
The longitude of physical features on Venus are expressed relative to its prime meridian. The original prime meridian passed through the radar-bright spot at the centre of the oval feature Eve, located south of Alpha Regio.
Much of the Venusian surface appears to have been shaped by volcanic activity. The only volcanic complex of this size on Earth is the Big Island of Hawaii.
Several lines of evidence point to ongoing volcanic activity on Venus. Sulfur dioxide concentrations in the atmosphere dropped by a factor of 10 between and , jumped in , and again declined fold.
In January , astronomers reported evidence that suggests that Venus is currently volcanically active. In and , the first direct evidence for ongoing volcanism was observed by Venus Express , in the form of four transient localized infrared hot spots within the rift zone Ganis Chasma ,  [n 1] near the shield volcano Maat Mons.
Three of the spots were observed in more than one successive orbit. These spots are thought to represent lava freshly released by volcanic eruptions.
Almost a thousand impact craters on Venus are evenly distributed across its surface. On other cratered bodies, such as Earth and the Moon, craters show a range of states of degradation.
On the Moon, degradation is caused by subsequent impacts, whereas on Earth it is caused by wind and rain erosion. Without plate tectonics to dissipate heat from its mantle, Venus instead undergoes a cyclical process in which mantle temperatures rise until they reach a critical level that weakens the crust.
Objects with less than a certain kinetic energy are slowed so much by the atmosphere that they do not create an impact crater.
The stratigraphically oldest tessera terrains have consistently lower thermal emissivity than the surrounding basaltic plains measured by Venus Express and Magellan , indicating a different, possibly a more felsic , mineral assemblage.
However, the nature of tessera terrains is far from certain. Without seismic data or knowledge of its moment of inertia , little direct information is available about the internal structure and geochemistry of Venus.
Like that of Earth, the Venusian core is at least partially liquid because the two planets have been cooling at about the same rate.
This results in reduced heat loss from the planet, preventing it from cooling and providing a likely explanation for its lack of an internally generated magnetic field.
Venus has an extremely dense atmosphere composed of This temperature is higher than that used for sterilization.
Venus' atmosphere is extremely enriched of primordial noble gases compared to that of Earth. An unusually large comet impact  or accretion of a more massive primary atmosphere from solar nebula  have been proposed to explain the enrichment.
However, the atmosphere is also depleted of radiogenic argon, a proxy to mantle degassing, suggesting an early shutdown of major magmatism.
Thermal inertia and the transfer of heat by winds in the lower atmosphere mean that the temperature of Venus' surface does not vary significantly between the planet's two hemispheres, those facing and not facing the Sun, despite Venus' extremely slow rotation.
Winds at the surface are slow, moving at a few kilometres per hour, but because of the high density of the atmosphere at the surface, they exert a significant amount of force against obstructions, and transport dust and small stones across the surface.
This alone would make it difficult for a human to walk through, even without the heat, pressure, and lack of oxygen. Above the dense CO 2 layer are thick clouds, consisting mainly of sulfuric acid , which is formed by sulfur dioxide and water through a chemical reaction resulting in sulfuric acid hydrate.
Clouds at different levels have different compositions and particle size distributions. The permanent cloud cover means that although Venus is closer than Earth to the Sun, it receives less sunlight on the ground.
The surface of Venus is effectively isothermal ; it retains a constant temperature not only between the two hemispheres but between the equator and the poles.
This substance likely formed from a similar process to snow, albeit at a far higher temperature. Too volatile to condense on the surface, it rose in gaseous form to higher elevations, where it is cooler and could precipitate.
The identity of this substance is not known with certainty, but speculation has ranged from elemental tellurium to lead sulfide galena.
Although Venus has no seasons as such, in astronomers identified a cyclical variation in sunlight absorption by the atmosphere, possibly caused by opaque, absorbing particles suspended in the upper clouds.
The variation causes observed changes in the speed of Venus' zonal winds, and appears to rise and fall in time with the Sun's year sunspot cycle.
The existence of lightning in the atmosphere of Venus has been controversial  since the first suspected bursts were detected by the Soviet Venera probes    In —07, Venus Express clearly detected whistler mode waves , the signatures of lightning.
Their intermittent appearance indicates a pattern associated with weather activity. According to these measurements, the lightning rate is at least half of that on Earth,  however other instruments have not detected lightning at all.
In , Venus Express discovered that a huge double atmospheric vortex exists at the south pole. In December , and to a lesser extent in April and May , researchers working on Japan's Akatsuki mission observed bow shapes in the atmosphere of Venus.
This was considered direct evidence of the existence of perhaps the largest stationary gravity waves in the solar system.
In , Venera 4 found Venus' magnetic field to be much weaker than that of Earth. This magnetic field is induced by an interaction between the ionosphere and the solar wind ,   rather than by an internal dynamo as in the Earth's core.
Venus' small induced magnetosphere provides negligible protection to the atmosphere against cosmic radiation. The lack of an intrinsic magnetic field at Venus was surprising, given that it is similar to Earth in size and was expected also to contain a dynamo at its core.
A dynamo requires three things: a conducting liquid, rotation, and convection. The core is thought to be electrically conductive and, although its rotation is often thought to be too slow, simulations show it is adequate to produce a dynamo.
On Earth, convection occurs in the liquid outer layer of the core because the bottom of the liquid layer is much higher in temperature than the top.
On Venus, a global resurfacing event may have shut down plate tectonics and led to a reduced heat flux through the crust. This would cause the mantle temperature to increase, thereby reducing the heat flux out of the core.
As a result, no internal geodynamo is available to drive a magnetic field. Instead, the heat from the core is reheating the crust. One possibility is that Venus has no solid inner core,  or that its core is not cooling, so that the entire liquid part of the core is at approximately the same temperature.
Another possibility is that its core has already completely solidified. The state of the core is highly dependent on the concentration of sulfur , which is unknown at present.
The weak magnetosphere around Venus means that the solar wind is interacting directly with its outer atmosphere.
Here, ions of hydrogen and oxygen are being created by the dissociation of neutral molecules from ultraviolet radiation. The solar wind then supplies energy that gives some of these ions sufficient velocity to escape Venus' gravity field.
This erosion process results in a steady loss of low-mass hydrogen, helium, and oxygen ions, whereas higher-mass molecules, such as carbon dioxide, are more likely to be retained.
Atmospheric erosion by the solar wind probably led to the loss of most of Venus' water during the first billion years after it formed.
Venus orbits the Sun at an average distance of about 0. Although all planetary orbits are elliptical , Venus' orbit is the closest to circular , with an eccentricity of less than 0.
All the planets in the Solar System orbit the Sun in an anticlockwise direction as viewed from above Earth's north pole.
Most planets also rotate on their axes in an anti-clockwise direction, but Venus rotates clockwise in retrograde rotation once every Earth days—the slowest rotation of any planet.
Because its rotation is so slow, Venus is very close to spherical. Venus' equator rotates at 6. Venus may have formed from the solar nebula with a different rotation period and obliquity, reaching its current state because of chaotic spin changes caused by planetary perturbations and tidal effects on its dense atmosphere, a change that would have occurred over the course of billions of years.
The rotation period of Venus may represent an equilibrium state between tidal locking to the Sun's gravitation, which tends to slow rotation, and an atmospheric tide created by solar heating of the thick Venusian atmosphere.
Venus has no natural satellites. Alex Alemi's and David Stevenson 's study of models of the early Solar System at the California Institute of Technology shows Venus likely had at least one moon created by a huge impact event billions of years ago.
An alternative explanation for the lack of satellites is the effect of strong solar tides, which can destabilize large satellites orbiting the inner terrestrial planets.
To the naked eye , Venus appears as a white point of light brighter than any other planet or star apart from the Sun. Venus "overtakes" Earth every days as it orbits the Sun.
Its greater maximum elongation means it is visible in dark skies long after sunset. As the brightest point-like object in the sky, Venus is a commonly misreported " unidentified flying object ".
As it orbits the Sun, Venus displays phases like those of the Moon in a telescopic view. The planet appears as a small and "full" disc when it is on the opposite side of the Sun at superior conjunction.
Venus shows a larger disc and "quarter phase" at its maximum elongations from the Sun, and appears its brightest in the night sky.
The planet presents a much larger thin "crescent" in telescopic views as it passes along the near side between Earth and the Sun.
Venus displays its largest size and "new phase" when it is between Earth and the Sun at inferior conjunction. Its atmosphere is visible through telescopes by the halo of sunlight refracted around it.
The Venusian orbit is slightly inclined relative to Earth's orbit; thus, when the planet passes between Earth and the Sun, it usually does not cross the face of the Sun.
Transits of Venus occur when the planet's inferior conjunction coincides with its presence in the plane of Earth's orbit.
The latest pair was June 8, and June 5—6, The transit could be watched live from many online outlets or observed locally with the right equipment and conditions.
The preceding pair of transits occurred in December and December ; the following pair will occur in December and December Historically, transits of Venus were important, because they allowed astronomers to determine the size of the astronomical unit , and hence the size of the Solar System as shown by Horrocks in The pentagram of Venus is the path that Venus makes as observed from Earth.
The ratio is approximate. Naked eye observations of Venus during daylight hours exist in several anecdotes and records.
Astronomer Edmund Halley calculated its maximum naked eye brightness in , when many Londoners were alarmed by its appearance in the daytime. French emperor Napoleon Bonaparte once witnessed a daytime apparition of the planet while at a reception in Luxembourg.
A long-standing mystery of Venus observations is the so-called ashen light —an apparent weak illumination of its dark side, seen when the planet is in the crescent phase.
The first claimed observation of ashen light was made in , but the existence of the illumination has never been reliably confirmed.
Observers have speculated it may result from electrical activity in the Venusian atmosphere, but it could be illusory, resulting from the physiological effect of observing a bright, crescent-shaped object.
Because the movements of Venus appear to be discontinuous it disappears due to its proximity to the sun, for many days at a time, and then reappears on the other horizon , some cultures did not recognize Venus as single entity;  instead, they assumed it to be two separate stars on each horizon: the morning and evening star.
The ancient Greeks also initially believed Venus to be two separate stars: Phosphorus , the morning star, and Hesperus , the evening star.
In the second century, in his astronomical treatise Almagest , Ptolemy theorized that both Mercury and Venus are located between the Sun and the Earth.
The 11th-century Persian astronomer Avicenna claimed to have observed the transit of Venus ,  which later astronomers took as confirmation of Ptolemy's theory.
When the Italian physicist Galileo Galilei first observed the planet in the early 17th century, he found it showed phases like the Moon, varying from crescent to gibbous to full and vice versa.
