18 lip 2013 · Satellites move through 24 time zones in a very short period of time, the ISS less than 100 minutes, so it makes sense to have a common anchor point. Typically, navigation systems use GPS time, while other systems use UTC time, and that is exactly what is used on the spacecraft.
The time it takes for a signal - which moves at the speed of light through space - to travel from the spacecraft to Earth. From Saturn, one-way light time can range from about one hour and 14 minutes to one hour and 24 minutes.
9 sie 2024 · The onboard clocks on these spacecraft are typically synchronized with Universal Time (UT), and communication between the spacecraft and Earth is carefully timed to account for the time it takes for signals to travel at the speed of light.
4 mar 2023 · Space organisations around the world are studying the best way to establish "a common lunar reference time". But how do you tell the time in space?
31 maj 2023 · Defining moon time would let astronauts work together and organize their days. It would be chaos if everyone followed their own time. On Earth, clocks and time zones are based on what’s known as Coordinated Universal Time, or UTC. (This reference time is equal to the old Greenwich Mean Time, or GMT, based in England.)
18 lip 2006 · An old trick is to adjust a clock to run 4 minutes a day fast, set it to local sidereal time, and use it to tell what constellations are on the meridian and what star charts to use. For instance, if the clock reads 5:30 a.m., right ascension 5h 30m is on your meridian, and there you'll find Orion.
26 sie 2022 · Have you ever wondered how the world clock works to keep everyone in sync? We live in different time zones, but from New York to Melbourne, a second is always a second.
