Ground track example from Heavens-Above.An observer in Sicily can see the International Space Station when it enters the circle at 9:26 p.m. The observer would see a bright object appear in the northwest, which would move across the sky to a point almost overhead, where it disappears from view, in the space of three minutes.
The idea is that since all the stars share a common space velocity, they will appear to move towards a point of common convergence ("vanishing point") on the sky. This is essentially a perspective effect. Using the moving-cluster method, the distance to a given star cluster (in parsecs) can be determined using the following equation:

Astronauts who had recently returned from space missions to the Hubble Space Telescope, the International Space Station and Mir Space Station reported seeing the LF under different conditions. In order of decreasing frequency of reporting in a survey, they saw the LF in the dark, in dim light, in bright light and one reported that he saw them ...
The Advanced Space Vision System (also known as the Space Vision System or SVS) is a computer vision system designed primarily for International Space Station (ISS) assembly. [1] The system uses regular 2D cameras in the Space Shuttle bay, on the Canadarm , or on the ISS along with cooperative targets to calculate the 3D position of an object.
NASA and SpaceX are still targeting a Saturday launch for the Crew-9 mission, whose astronauts will head to orbit aboard a Dragon spacecraft that will bring the Starliner crew back to Earth next ...
The Monitor of All-sky X-ray Image (MAXI) is an X-ray telescope mounted on the International Space Station since 2009. The instrument uses wide field of view X-ray detectors to perform a sky survey, measuring the brightness of X-ray sources every 96 minutes (one ISS orbit).
Visual conjunction between the Moon and the planet Venus, the two brightest objects in the night sky. In astronomy, a conjunction occurs when two astronomical objects or spacecraft appear to be close to each other in the sky. This means they have either the same right ascension or the same ecliptic longitude, usually as observed from Earth. [1] [2]
