The most accurate space clock set as a launch -and calculated by destruction

The most accurate clock in the universe runs within a few days and begins to build a highly synchronized network in the best clocks on Earth. However, the project, which has been prepared for decades, will be operated only for several years before it burned at the end of 10 years.

The Atomic Clock Ensemble in Space (ACES) is a European Space Agency (ESA) mission that creates an unprecedented accuracy time signal and transmits nine ground stations through a laser when passing 27,000 kilometers of overhead. This watch network will be very close to the world and provides very accurate time maintenance around the world.

As a result, ACES can test Einstein’s general theory of relativity, which means that the passage of time is greatly affected by the intensity of gravity. It will also help you study everything from dark material to string theory.

ACES will be released on April 21 at the SPACEX FALCON 9 rocket at the Kennedy Space Center in Florida. In ISS, Canadarm2, a robot of Canadian Space Agency, is attached to the outside of the Columbus lab of ESA and remains in the vacuum of the universe.

The package actually consists of two watches. One called SHM has the ability to maintain stability for a short time, which can help to correct the other called Pharao. This watch will lose less than 1 second in 300 million years. Ten times more accurate than the watch on the GPS satellite.

Pharaohs basically model the atomic clock in Paris and occupy the entire room. It was meaningless to occupy the technology less than a cubic meter and to mini -dietary technology that could survive the rocket launch and the strictness of space life.

To create an accurate clock signal, Pharao sprinkles the cooled cesium atoms near the absolute zero and observes the interaction with the microwave field. On Earth, you need a device of up to 3 meters tall, but in fine shooting, you can move this atom slowly and sprinkle it on a small fountain to be much smaller.

Simon Wineberg The ESA says that this device is so sensitive that you can create an electronic field that can be destroyed by simply leaving a teaspoon nearby. Weinberg said, “To fall in the context, it is better to measure here than one second.” So that’s the hell of challenging job. “

The concept of ACES dates back to the 1990s and planned to be launched on a space shuttle that retired in 2011. When you arrive in space, the first signal will not arrive at Earth Bound Clock for a year and a half, and it will take about six months to request a device.

Since then, the ACES is operated until 2030, and then ISS deliberately crashed into the earth’s atmosphere. At this point, the new seconds of clocks, known as optical clocks, are likely to have made the atomic clock useless on Earth.

Wineberg said at some point that ESA will launch the next -generation ace to replace what’s lost in ISS, any of the most appropriate technology at the time. “We will have a long way to do so, and we will have to collect support and financing to see if it has happened.”
