National Aeronautics and Space Administration (NASA) sent an atomic clock to space on Monday (24/6).
This clock is 50 times more accurate than an atomic clock on a GPS satellite. The old one accuracy only changes one second every 10 years.
This clock is about the size of a toaster. As reported by Science Alert, Monday (24/6), a clock called Deep Space Atomic Clock can revolutionize a deep space trip.
Next year is a very important time for the development of the Deep Space Atomic Clock. NASA will monitor its performance when it orbits Earth at a height of 720 kilometers (447 miles). The object will be launched from Falcon SpaceX rocket, that belongs to SpaceX.
GPS satellites send nonstop of the light-speed radio signals. These signals transmit the location and time when they leave the satellite.
The receiver on the Earth, for example, the phones. It will measure the delay time of each satellite, and convert it into the spatial coordinates. This is also a way of navigating a spacecraft.
As might be imagined, the more accurate the clock, then the better the location data would be. This is where this clock comes in.
Deep Space Atomic Clock is based on the electrically charged mercury atoms that contained in electromagnetic traps. When the energy is increasing, these charged the atoms to produce optical ‘ticks’.
NASA revealed the Deep Space Atomic Clock is up to 50 times more accurate than the old one.
These are oscillator cesium and rubidium that now still in the orbit. This is as stable as atomic clocks on the land that forms the basis of their navigation.
This means, instead of the two-way signal system that currently in the use, space atomic clocks can be used to do tracking calculations on the spacecraft. The time is right after the signals received on the Earth.
One-way tracking will mean faster, and more flexible navigation, with minimal input from the Earth. This results in faster response times for the unexpected events and correction of more agile courses. So that can be said the spacecraft now can adapt quickly.
In the turn, this will ease NASA’s burden on the Deep Space Network from a radio telescope. So it can allow managing many space cruisers together as they explore the Solar System, without the need for the expansion. It can change the way humans crossing the stars.
