Soyuz 9 carried cosmonauts Andrian Nikolayev & Vitali Sevastyanov to orbit. The mission lasted 17 days, 16 hours & 58 minutes completing 288 orbits around Earth. They broke the endurance record held by Gemini 7 for 5 years. This was the first crewed space launch that lifted off at night. As of 2016 it still holds the record for longest crewed flight by a solo spacecraft. The goal of the mission was to conduct various pysiological and biomedical experiments on themselves and invastigate possible social implications of extended duration spaceflight.
Low Earth OrbitDong Fang Hong 1 (DFH-1) was the first Chinese satellite. This was the first satellite launched by China on its own booster, making China the fifth nation to put a spacecraft into orbit using its own rocket. The satellite was developed under the direction of Tsien Hsue-Shen, dean of the Chinese Academy of Space Technology (CAST). The experimental satellite was a nearly spherically shaped symmetrical 72-faced polyhedron with a 1-meter diameter. It was battery-powered and carried a radio transmitter. The primary mission was to broadcast the song "Dong Fang Hong", paying tribute to Chairman Mao, and to announce the time. A total of five identical satellites were built to have backups in case of launch failures. The first satellite launched successfully.
