Second, NASA considers the present space station, the International Space Station (ISS), to be valuable as a zero gravity laboratory, and its current microgravity environment was a conscious choice. [7] In the 2010s, NASA explored plans for a Nautilus X centrifuge demonstration project. If flown, this would add a centrifuge sleep quarters ...
The James Webb Space Telescope, a powerful infrared space observatory, is located at L 2. [4] This allows the satellite's sunshield to protect the telescope from the light and heat of the Sun, Earth and Moon simultaneously with no need to rotate the sunshield. The L 1 and L 2 Lagrange points are located about 1,500,000 km (930,000 mi) from Earth.
Centrifugal force is a fictitious force in Newtonian mechanics (also called an "inertial" or "pseudo" force) ... as in proposed designs for rotating space stations.
In the context of a rotating space station, it is the radial force provided by the spacecraft's hull that acts as centripetal force. Thus, the "gravity" force felt by an object is the centrifugal force perceived in the rotating frame of reference as pointing "downwards" towards the hull.
One is the effects of centrifugal force upon the shape of the surface of water rotating in a bucket, equivalent to the phenomenon of rotational gravity used in proposals for human spaceflight. The second is the effect of centrifugal force upon the tension in a string joining two spheres rotating about their center of mass.
A halo orbit is a periodic, three-dimensional orbit associated with one of the L 1, L 2 or L 3 Lagrange points in the three-body problem of orbital mechanics.Although a Lagrange point is just a point in empty space, its peculiar characteristic is that it can be orbited by a Lissajous orbit or by a halo orbit.
A space vehicle's flight is determined by application of Newton's second law of motion: =, where F is the vector sum of all forces exerted on the vehicle, m is its current mass, and a is the acceleration vector, the instantaneous rate of change of velocity (v), which in turn is the instantaneous rate of change of displacement.
The International Liquid Mirror Telescope is a 4-meter telescope located inside the premises of Aryabhatta Research Institute of Observational Sciences (ARIES) in the city of Nainital, Uttarakhand, India. It is the first liquid-mirror telescope for astronomy in Asia and the largest liquid-mirror telescope of the world. [1]
