Red is such a pretty color!  Mars is a red planet, and the red color comes from iron oxide!
Iron oxide also gives the red color to the planet Mars.

Red
Red is the colour at the end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy. The red sky at sunset results from Rayleigh scattering, while the red color of the Grand Canyon and other geological features is caused by hematite or red ochre, both forms of iron oxide.
Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury. In English, Mars carries a name of the Roman god of war, and is often referred to as the "Red Planet" because the reddish iron oxide prevalent on its surface gives it a reddish appearance that is distinctive among the astronomical bodies visible to the naked eye. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth. The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons.
List of The King of Braves GaoGaiGar characters
This is an index of characters and mecha in the anime and manga "The King of Braves GaoGaiGar" and "The King of Braves GaoGaiGar FINAL". A brave man with tremendous courage and enthusiasm, and the strength to never give up for the sake of life—even at the possible cost of his own. Former astronaut and test pilot for the Space Development Corporation. In 2003, he had been in orbit testing an experimental space shuttle when an extraterrestrial object (later classified as EI-01) suddenly appeared in his flight path, smashing his shuttle out of the way. This left the shuttle disabled and Guy himself in a near-death state.
Iron
Iron is a chemical element with symbol Fe (from ) and atomic number 26. It is a metal in the first transition series. It is by mass the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. Its abundance in rocky planets like Earth is due to its abundant production by fusion in high-mass stars, where it is the last element to be produced with release of energy before the violent collapse of a supernova, which scatters the iron into space. Like the other group 8 elements, ruthenium and osmium, iron exists in a wide range of oxidation states, −2 to +7, although +2 and +3 are the most common.
Journey into Space
Journey Into Space is a BBC Radio science fiction programme written by BBC producer Charles Chilton. It was the last UK radio programme to attract a bigger evening audience than television. Originally, four series were produced (the fourth was a remake of the first), which was translated into 17 languages (including Hindustani, Turkish and Dutch) and broadcast in countries worldwide (including the United States, New Zealand, Australia and the Netherlands). Chilton later wrote three best-selling novels and several comic strip stories based upon the radio series. The first series was created in 1953, soon after "Riders of the Range" (a popular Western, also written by Chilton) ended its six series on the BBC Light Programme.
Glass-to-metal seal
Glass-to-metal seals are a very important element of the construction of vacuum tubes, electric discharge tubes, incandescent light bulbs, glass encapsulated semiconductor diodes, reed switches, pressure tight glass windows in metal cases, and metal or ceramic packages of electronic components. Properly done, such a seal is hermetic (vacuum tight, good electrical insulation, special optical properties e.g. UV lamps). To achieve such a seal, two properties must hold:  Thinking for example about a metal wire in a glass bulb sealing, the metal glass contact can break if the CTEs (coefficient of thermal expansion) are not well aligned.
Hematite
Hematite, also spelled as haematite, is the mineral form of iron(III) oxide (FeO), one of several iron oxides. It is the iron oxide mineral and is widespread in rocks and soils. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum. Hematite and ilmenite form a complete solid solution at temperatures above . Hematite is colored black to steel or silver-gray, brown to reddish brown, or red. It is mined as the main ore of iron. Varieties include "kidney ore", "martite" (pseudomorphs after magnetite), "iron rose" and "specularite" (specular hematite).
