The China National Space Administration (CNSA) was established in 1993 as China’s civil space authority. By the end of 2024, China operated more than 1,060 active satellites in orbit, a count that has grown more than six-fold since 2015. Chang’e-4 achieved the first landing on the Moon’s far side in 2019. Micius (Mozi), launched in…

The Black Knight legend links Nikola Tesla’s 1899 reports of periodic radio signals from Colorado Springs to the idea of an ancient satellite in Earth orbit. In 1927 Jørgen Hals observed long-delayed echoes, and in 1973 Duncan Lunan claimed a star map pointing to Epsilon Boötes suggesting a 13,000-year-old alien probe, later retracting parts of…
