Well, if I can join, I call from the '[Desert world]'!

A MAJOR WIP

//////Name: Setekh.

/////Subject: Planet.

////Location: Epsilon Eridani.

///Geography: The planet has some craters, that are as large as 60 km and smaller than 10 km. Since Setekh has no oceans and hence no 'sea level', it is convenient to define an arbitrary zero-elevation level or "datum" for mapping the surface. The datum for Setekh is arbitrarily defined in terms of a constant atmospheric pressure. There is 610.5 Pa (6.105 mbar), on the basis that below this pressure liquid water can never be stable (i.e., the triple point of water is at this pressure). This value is only 0.6% of the pressure at sea level, which forms the zero elevation datum for our planet. Note that the choice of this value does not mean that liquid water does exist below this elevation, just that it could were the temperature to exceed 273.16 K.

There is a dichotomy between the northern and southern hemispheres. Most of the northern hemisphere is flat, with few impact craters, and lies below the conventional ‘zero elevation’ level. In contrast, the southern hemisphere is mountains and highlands, mostly well above zero elevation. The two hemispheres differ in elevation by 1 to 3 km. One distinctive feature is the fretted terrain. It contains mesas, knobs, and flat-floored valleys having walls about a mile high. Around many of the mesas and knobs are lobate debris aprons that have been shown to be rock-covered glaciers. There is also large river valleys and outflow channels that cut through the dichotomy.

The river valleys and outflow channels are empty of course, but this could lead that Setekh once had water. The idea of how Setekh got to the wasteland of where it's today is that, a large comet hit on the side of the planet, which caused it to move by a couple of feet. Which caused the planet to go dry faster and after the planet was empty of water, the sand began to form.

//Atmosphere: The atmosphere of Setekh has around 96% carbon dioxide, 1.93% argon and 1.89% nitrogen along with traces of oxygen and water. The atmosphere is quite dusty, containing particulates about 1.5 µm in diameter which give the skies the light tan color when seen from the surface. The scale height of the atmosphere is about 10.8 km (6.7 mi) because the surface gravity of Setekh is only about 38%, an effect offset by both the lower temperature and 50% higher average molecular weight of the atmosphere. The solar wind interacts directly with the ionosphere, lowering the atmospheric density by stripping away atoms from the outer layer.

Methane has been detected in the atmosphere of Setekh with a mole fraction of about 30 ppb; it occurs in extended plumes, and the profiles imply that the methane was released from discrete regions. In northern midsummer, the principal plume contained 19,000 metric tons of methane, with an estimated source strength of 0.6 kilogram per second. Volcanic activity, cometary impacts, and the Aasiths are among possible sources. Methane could also be produced by a non-biological process called serpentinization involving water, carbon dioxide, and the mineral olivine, which is known to be common on Setekh.

It could come from a byproduct of electrical discharges from dust devils and dust storms or the result of UV radiation. Setekh also has a metal-poor core, generating a weak magnetic field and allowing more solar radiation into the atmosphere.

//////Name: Aasiths.

/////Subject: Intelligent Species.

////Location: On the desert planet of Setekhin the Epsilon Eridani.

///Physiology/Biology:

Due to Setekh having a metal-poor core, generating a weak magnetic field and allowing more solar radiation into the atmosphere. To deal with this, they evolved some form of metallic "exoskeleton" to protect themselves. Their reflective plate-like skin makes them less susceptible to long-term, low-level radiation exposure, but they do not possess any sort of "natural armor". Their blood has a dark blue colouration because of that. It was differcult from the Aasiths to devolpe a nose or the ability to smell, so their eye sight got better. The lower class (the poor and homeless) had to lived in the surface because of that, their eye sights are better than the Aasiths living underground.

Nation's full name:

Estados Unidos do Brasil (United States of Brazil).

Population:

56,739,000 Brazilians.

Current leadership:

Gaspar Dutra - President of United States of Brazil.
Nereu Ramos - Vice President of United States of Brazil.

Government Type:

(República presidencial) Presidential Republic.

Military Strength:

327,000 Active Service Men and 2,000,000 Reservists.

State of the Union Summary:

With Brazil being the first South American country to join the Allies in World War II, they grew in power as their annual Gross National Product (GNP) growth rate was among the highest in the world averaging. That was in part of the debts that the countries were in and the damages that most countries had to rebuild due to Nazi Germany. At the end of World War II, political and economic liberalism were reintroduced in Brazil. Getúlio Dorneles Vargas was overthrown, democratic rule was reestablished, and the foreign-exchange reserves accumulated during the war made possible a reduction of trade restrictions. However, trade liberalization was short-lived. The overvalued foreign-exchange rate, established in 1945. This, combined with persistent inflation and a repressed demand, meant sharp increases in imports and a sluggish performance of exports, which soon led again to a balance of payments crisis.
