“The most savage controversies are those about matters as to which there is no good evidence either way. Persecution is used in theology, not in arithmetic, because in arithmetic there is knowledge, but in theology there is only opinion.”

“All laws which can be broken without any injury to another, are counted but a laughing-stock, and are so far from bridling the desires and lusts of men, that on the contrary they stimulate them.”

“Individuals have rights and there are things no person or group may do to them (without violating their rights). So strong and far-reaching are these rights that they raise the question of what, if anything, the state and its officials may do. How much room do individual rights leave for the state?”

“If only it were all so simple! If only there were evil people somewhere insidiously committing evil deeds, and it were necessary only to separate them from the rest of us and destroy them. But the line dividing good and evil cuts through the heart of every human being. And who is willing to destroy a piece of his own heart?”

— Aleksandr Solzhenitsyn, The Gulag Archipelago 1918-1956

[catherineaddington-deactivated2]

“Gradually it was disclosed to me that the line separating good and evil passes not through states, nor between classes, nor between political parties either, but right through every human heart, and through all human hearts. This line shifts. Inside us, it oscillates with the years. Even within hearts overwhelmed by evil, one small bridgehead of good is retained; and even in the best of all hearts, there remains a small corner of evil.”

— Alexander Solzhenitsyn, “The Gulag Archipelago”

“People hate the truth for the sake of whatever it is that they love more than truth. They love truth when it shines warmly on them, and hate it when it rebukes them. The truth is like a lion. You do not have to defend it. Let it loose. It will defend itself.”

— St. Augustine, Bishop of Hippo

KSLV-II TLV flight validates South Korean rocket engine for future launch vehicle. (November 29, 2018)

South Korea became the 11th country in the world yesterday to successfully develop and test an indigenously-made liquid fueled rocket engine. The Korea Aerospace Research Institute launched a test version of the KSLV-II rocket from the Naro spaceport November 28 in order to validate the design of the KRE-075 engine during flight conditions.

Powered by a single, 75-ton force KRE-075 vacuum engine, the 25.8 meter tall test vehicle represented the second stage of the three-stage KSLV-II rocket still in development. The vehicle’s upper stage was a dummy and not operational during the mission. Liftoff occurred at 4pm Korean Standard Time (2am EST) from the Naro Space Center on the country’s southern coast. Burning for 151 seconds, the KRE-075 engine placed the vehicle in a suborbital trajectory southward over the East China Sea, reaching an apogee of 209 kilometers 319 seconds after liftoff. KARI reported the test vehicle safely impacted the ocean 429 kilometers downrange from the launch site. This marked the first test of the combined engine and second stage systems during flight conditions. Engineers have conducted over 100 ground tests of the engine prior to Wednesday’s flight.

Development of a domestic satellite launch vehicle has been a goal for South Korea for decades but political pressures from the United States have hindered development of the technology due to its similarities with ballistic missile technology.

South Korean engineers began development of KSLV-II following the country’s first successful domestic satellite launch in 2013. That payload was launched by the Naro-1 vehicle, a joint South Korean-Russian rocket derived from the Angara rocket’s core stage. Following yesterday’s test, KARI will push towards a full-stack test flight of the complete vehicle by 2021. When operational, KSLV-II is expected to deliver up to 1.5 tons to low Earth orbit.
