Gagarin's flight, part of the Soviet Vostok space exploration program, took 108 minutes and consisted of a single orbit of the Earth. [citation needed] On August 7, 1961, Gherman Titov, another Soviet cosmonaut, became the second man in orbit during his Vostok 2 mission. Titov orbited Earth 17 times in over 25 hours during his spaceflight. [17]
Spacecraft flight dynamics is the application of mechanical dynamics to model how the external forces acting on a space vehicle or spacecraft determine its flight path. These forces are primarily of three types: propulsive force provided by the vehicle's engines; gravitational force exerted by the Earth and other celestial bodies; and ...

Spaceflight (or space flight) is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board. Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth , but also includes space probes for flights beyond Earth orbit.
Earth's rotation. Earth's rotation or Earth's spin is the rotation of planet Earth around its own axis, as well as changes in the orientation of the rotation axis in space. Earth rotates eastward, in prograde motion. As viewed from the northern polar star Polaris, Earth turns counterclockwise. The North Pole, also known as the Geographic North ...
An orbital spaceflight (or orbital flight) is a spaceflight in which a spacecraft is placed on a trajectory where it could remain in space for at least one orbit. To do this around the Earth , it must be on a free trajectory which has an altitude at perigee (altitude at closest approach) around 80 kilometers (50 mi); this is the boundary of ...
For the purpose of these lists, a spaceflight is defined as any flight that crosses the Kármán line, the FAI -recognized edge of space, which is 100 kilometres (62 miles) above mean sea level (AMSL). The timeline contains all flights which have crossed the edge of space, were intended to do so but failed, or are planned in the near future.
Google Maps Street View Trekker backpack being implemented on the sidewalk of the Hudson River Greenway in New York City. In late 2014, Google launched Google Underwater Street View, including 2,300 kilometres (1,400 mi) of the Australian Great Barrier Reef in 3D. The images are taken by special cameras which turn 360 degrees and take shots ...
