Log entry #1: first suitable system observed

TS-H01 system map

After almost two months of working on newly established Tromelin observatory and having scanned over 300 systems in the vicinity to Brittany, first supposedly fitting our search criteria system was found in the distance of 7.4 light-years away from Brittany. The system working name is TS-H01

The local star (TS-H01α) is an AII-class blue bright giant with an estimated 9,000K surface temperature. The age of the star is approximately 4 billion years, and it is supposedly stable.

The planets of the system are represented with three major stellar objects.

Two planets are terrestrial. The first one, TS-H01-a is located distant from the star and beyond the habitability zone. The atmosphere is, probably, non-existent or very thin. The planet is likely devoid of the magnetosphere as well, however, it is difficult to trace the minor fluctuations in cosmic rays intensity in the vicinity of the planet to make the final judgement. According to spectral analysis, the planetary crust has significant deposits of Uranium, Iron, Zinc.

The second terrestrial planet, TS-H01-b is located in a local asteroid field that significantly hampered our observation due to additional shifts in spectral analysis. Due to its location within the asteroid field and significant presence of ice dust in space around the planet, TS-H01-b is likely not getting enough sunlight to be interesting for colonisation. However, it still can contain valuable natural resources. Further study of TS-H01-b would require surveying.

The third planet in the system, TS-H01-c, is a class-III gas giant. It is located closer to the star than the other two planets. Its proximity is likely the reason for it to contain large amounts of Helium in the atmosphere due to Hydrogen evaporating under the heat of the star. TS-H01-c might be useful for Helium-extracting operations in the future.

What is more significant that drew our attention to the system is one of the moons, and the only large one, of the gas giant in question. TS-H01-c1 appears to be a terrestrial world with a significant presence of water. Its atmosphere consists predominantly of Oxygen and Nitrogen in proportions likely suitable for human habitation. The gravitation is estimated to be 0.86 of New Paris, indicating a hot metallic core. The moon has extra protection from cosmic radiation due to proximity to TS-H01-c and being covered with its magnetosphere. The moon is not tidally locked and rotates around the parent gas giant with a period of 41 days. This indicates a small problem for the colonisation - long nights lasting up to 17 days. However, we are hypothethising that the thick atmosphere of the moon and the heat emanating from the gas giant can support the temperature high enough for humans to exist even during the long night as the spectral analysis of the orbiting cycle did not indicate ubiquitous freezing of the water on the surface during the nocturnal period.

Having considered the information above, we deem the system suitable for colonisation and are suggesting to the corporate leadership and Monsieur Baron to evaluate the planet in terms of its value. If agreed upon, it is important to start constructing the experimental “slingshot” wormhole generator installation for further surveying and exploration of the system.
