A sister moon of Zion, this temperate E-Class world was ignored at the time for terraforming as the process would be too expensive. However after mining the other asteroid moons of Caelum the inhabitants of Zion had enough to terraform the smaller moon.
In 2505 the terraforming began but due to the increased tensions between many of the URSS worlds not much was put into the terraforming. Unlike its sister world it took half a millennium before the moon was completed. Many Zionites came to settle the new world as did many Martian Christians surprisingly enough. The two sister worlds enjoyed mutual cooperation but the difference in the worlds soon began showing.
While still friendly today, the cultures on the worlds are different thanks to the physical characteristics of Shalem.
The worldwide population of Shalem is 2.2 billion.
Because of the lower gravity of Shalem, the inhabitants are more laid back and relaxed, not wanting to leave their paradise to help the rest of the universe like their sister world of Zion. The locals are also much taller and thinner than their Zion counterparts and are more open to genetic engineering than Zionites.
Shalemites, having gone through genetic engineering in the past, can now stay up at all times during their local day but this means that they can also sleep during all the night of their world. Plants and animals had to be modified to fit this change as well.
Shalem is smaller than Zion at only 6364.1 km diameter and a gravity half that of Earth. Tidally locked to Caelum, it has a semimajor axis of 684019.3 km giving it a day length of 2.8 days which the locals have since gotten used to thanks to genetic engineering.
Upon its discovery the moon had a low atmospheric pressure of 0.2 and a mean temperature of -13.1 °C. After terraforming the moon has a much higher atmospheric pressure of 0.9 and a mean temperature of 10 °C.Due to its longer day cycle, the world is cooler than Zion with large ice caps and snow covered mountains everywhere. However, the local sun does warm the day side rather well.
