Unit 731 (Japanese: 731部隊, Hepburn: Nana-san-ichi Butai), [note 1] short for Manchu Detachment 731 and also known as the Kamo Detachment [3]: 198 and the Ishii Unit, [5] was a covert biological and chemical warfare research and development unit of the Imperial Japanese Army that engaged in lethal human experimentation and biological weapons manufacturing during the Second Sino-Japanese War ...
The object was tentatively identified as Epimetheus, a moon discovered the previous day from Pioneer ' s imaging, and suspected from earlier observations by Earth-based telescopes. After the Voyager flybys, it became known that there are two similarly sized moons (Epimetheus and Janus ) in the same orbit, so there is some uncertainty about ...
This is a timeline of Solar System exploration ordering events in the exploration of the Solar System by date of spacecraft launch. It includes: It includes: All spacecraft that have left Earth orbit for the purposes of Solar System exploration (or were launched with that intention but failed), including lunar probes .
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
The motion of these objects is usually calculated from Newton's laws of motion and the law of universal gravitation. Orbital mechanics is a core discipline within space-mission design and control. Celestial mechanics treats more broadly the orbital dynamics of systems under the influence of gravity , including both spacecraft and natural ...
Discovery and exploration of the Solar System is observation, visitation, and increase in knowledge and understanding of Earth's "cosmic neighborhood". [1] This includes the Sun , Earth and the Moon , the major planets Mercury , Venus , Mars , Jupiter , Saturn , Uranus , and Neptune , their satellites , as well as smaller bodies including ...
He was the first to demonstrate the motion of the solar apogee relative to the fixed background of the stars, measuring its rate of motion as 12.9 seconds per year, which is remarkably close to the modern calculation of 11.77 seconds. [50] Al-Zarqālī also contributed to the famous Tables of Toledo.
This false assumption relies on incorrect Aristotelian physics that an object needs to be pushed to maintain motion. The propelling force from the Sun is inversely proportional to the distance from the Sun. Kepler reasoned this, believing that gravity spreading in three dimensions would be a waste, since the planets inhabited a plane.
