Artificial Atmosphere is a Horatio-specific technology on the Applied Sciences technology tree with a research cost of 1800 
. It unlocks a Star System Improvement, requires research in Non Baryonic Particles or in Extreme Metallurgy, and permits no further research.
"While the technology does not have the power to cover an entire planet, discoveries in particle physics and shielding permit localized control over the effects of radiation."

Cost: 500 
"The great variance between the levels of radiation and light in different star systems makes agriculture an expensive process of continual adaptation. However, the use of shield effect technology can simplify this, allowing local re-creation of ideal or standard conditions to speed and simplify crop development."
