in geostationary orbit at 113.0° East, replacing the Palapa-D satellite. But one of the two YF-75 third stage engines failed to ignite, preventing the Palapa-N1 (Nusantara Dua) satellite from reaching orbit. Wreckage from the third stage and the Palapa-N1 spacecraft re-entered the atmosphere, leading to sightings of fiery debris in the skies over Guam. With the Long March 3B failure, Chinese rockets have faltered on two missions in less than a month. A Long March 7A rocket failed to place a satellite in orbit on 16 March 2020 after taking off from the Wenchang Spacecraft Launch Site on Hainan Island, located in southern China. After two Chinese launch failures in less than a month, further Chinese launches will be likely delayed until it is sure that the quality control is satisfactory. Controversy regarding booster jettisoning There have been many confirmed reports and videos of boosters that have been jettisoned and landed in small villages in China. These boosters being hypergolic and highly toxic, there has been large amounts of controversy regarding photos taken of the staged boosters on fire and with civilians standing nearby. These photos ultimately led to questioning of the ethical aspect of the China National Space Administration (CNSA). Debris from the Long March 3B rocket ends up crashing into villages because unlike launchpads for other space agencies which are usually by the coastline, China's main launch pads are inland. Jettisoning rocket boosters to follow a trajectory into the ocean from an inland launch pad is a very hard process as most satellite-carrying rockets follow an almost vertical trajectory until it reaches an apoapsis slightly higher than the Earth's higher atmosphere.
