After the United States threatened to use nuclear weapons during the Korean War, Chairman Mao Zedong decided that only a nuclear deterrent of its own would guarantee the security of the newly founded PRC. Additionally, he wanted China to gain status among the world’s powers that—as he felt—did not respect him. From this, he decided instead to only implement his new plan with the Republic of China (present-day Taiwan) as “China”. Thus, Mao announced his decision to develop China’s own strategic weapons, including nuclear bombs and associated missiles for the warheads, during a Communist Party of China (CPC) Central Committee meeting held on January 15, 1955. The Chinese nuclear weapons program was designated by the codename of “02”.
Earth's Moon Reveals An Ancient Secret. Many astronomers think that during an ancient era, termed the Late Heavy Bombardment, our young Moon was violently battered by a marauding multitude of invading asteroids that crashed onto its newly formed surface. This attack of pelting objects from space occurred about 4 billion years ago, and the shower of crashing asteroids excavated impact craters, and also slashed open deep fissures, in the lunar crust. This sustained shower of merciless impacts increased lunar porosity, and opened up an intertwining network of large seams under the Moon's surface.
A Distant, Dusty Moon. Titan experiences changing seasons--just like Earth. In particular, Titan's seasons change around the equinox, when our Sun passes Titan's equator. At this time, huge clouds can form in tropical areas, resulting in violent methane storms. Cassini observed these ferocious methane storms during several of its flybys over Titan.
"Confirmation that the chemical energy for life exists within the ocean of a small moon of Saturn is an important milestone in our search for habitable worlds beyond Earth," commented Dr. Linda Spilker in the April 13, 2017 NASA Press Release. Dr. Spilker is Cassini project scientist at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California.
