Space, time The continual question --br-- If time moves differently on the peaks of mountains than the shores of the ocean, you can imagine that things get even more bizarre the farther away from Earth you travel. --br-- Площадка кракен --br-- To add more complication Time also passes slower the faster a person or spacecraft is moving, according to Einstein s theory of special relativity. --br-- --br-- Astronauts on the International Space Station, for example, are lucky, said Dr. Bijunath Patla, a theoretical physicist with the US National Institute of Standards and Technology, in a phone interview. Though the space station orbits about 200 miles (322 kilometers) above Earth s surface, it also travels at high speeds looping the planet 16 times per day so the effects of relativity somewhat cancel each other out, Patla said. For that reason, astronauts on the orbiting laboratory can easily use Earth time to stay on schedule. --br-- https kra30c.cc --br-- кракен вход --br-- For other missions it s not so simple. --br-- --br-- Fortunately, scientists already have decades of experience contending with the complexities. --br-- --br-- Spacecraft, for example, are equipped with their own clocks called oscillators, Gramling said. --br-- --br-- They maintain their own time, Gramling said. And most of our operations for spacecraft even spacecraft that are all the way out at Pluto, or the Kuiper Belt, like New Horizons (rely on) ground stations that are back on Earth. So everything they re doing has to correlate with UTC. --br-- But those spacecraft also rely on their own kept time, Gramling said. Vehicles exploring deep into the solar system, for example, have to know based on their own time scale when they are approaching a planet in case the spacecraft needs to use that planetary body for navigational purposes, she added. --br-- --br-- For 50 years, scientists have also been able to observe atomic clocks that are tucked aboard GPS satellites, which orbit Earth about 12,550 miles (20,200 kilometers) away or about one-nineteenth the distance between our planet and the moon. --br-- --br-- Studying those clocks has given scientists a great starting point to begin extrapolating further as they set out to establish a new time scale for the moon, Patla said. --br-- --br-- We can easily compare (GPS) clocks to clocks on the ground, Patla said, adding that scientists have found a way to gently slow GPS clocks down, making them tick more in-line with Earth-bound clocks. Obviously, it s not as easy as it sounds, but it s easier than making a mess.

Lunar clockwork --br-- What scientists know for certain is that they need to get precision timekeeping instruments to the moon. --br-- kraken войти --br-- Exactly who pays for lunar clocks, which type of clocks will go, and where they ll be positioned are all questions that remain up in the air, Gramling said. --br-- --br-- We have to work all of this out, she said. I don t think we know yet. I think it will be an amalgamation of several different things. --br-- https kra30c.cc --br-- kraken войти --br-- Atomic clocks, Gramling noted, are great for long-term stability, and crystal oscillators have an advantage for short-term stability. --br-- You never trust one clock, Gramling added. And you never trust two clocks. --br-- --br-- Clocks of various types could be placed inside satellites that orbit the moon or perhaps at the precise locations on the lunar surface that astronauts will one day visit. --br-- --br-- As for price, an atomic clock worthy of space travel could cost around a few million dollars, according Gramling, with crystal oscillators coming in substantially cheaper. --br-- --br-- But, Patla said, you get what you pay for. --br-- --br-- The very cheap oscillators may be off by milliseconds or even 10s of milliseconds, he added. And that is important because for navigation purposes we need to have the clocks synchronized to 10s of nanoseconds. --br-- --br-- A network of clocks on the moon could work in concert to inform the new lunar time scale, just as atomic clocks do for UTC on Earth. --br-- --br-- (There will not, Gramling added, be different time zones on the moon. There have been conversations about creating different zones, with the answer No, she said. But that could change in the future. )
