What was the mission of the KH-10 Dorian?
The KH-10 ( BYEMAN codename DORIAN) was the classified designation for the reconnaissance mission and equipment of the experimental Manned Orbiting Laboratory (MOL).

What makes up the kh in an aquarium?
KH is the capacity of water to neutralize acids and KH is made up of compounds such as carbonate, bicarbonate, hydroxide, and sometimes borate & silicate. A higher KH can neutralize more acids produced from aquarium/pond biological processes than a lower KH.
Why are kh and GH important to plants?
KH (carbonate hardness) is an important source of energy for nitrifying bacteria that eliminate ammonia and nitrite. In addition, carbonates may be used by plants for photosynthesis when carbon dioxide (CO2) is absent.
