NASA Commissioned by US Government to Repair Time Zone on Moon: Coordinated Lunar Time (CLT)

Jakarta – Government United States of America commissioned his space agency, NASAto repair time zone normal for mooncalled Coordinated Lunar Time (CLT).

In a memo released on April 2, 2024, the US Office of Science and Technology Policy (OSTP) said: “Federal agencies will develop space-time standards with an initial focus on surfaces. moon and missions operating in Cislunar space (the area within orbit moon), with tracking capabilities sufficient to support missions to other celestial bodies.”

“Traceability” means that the CLT can remain in compliance with it time zone on earth.

The memo describes the following features for the new CLT:

Find Coordinated Universal Time (UTC – a compromise for English and French speakers);

Sufficient precision to support precision navigation and science;

Resists loss of communication with Earth (meaning the CLT can operate independently of Earth);

Scalability to space environments outside the Earth-Moon system (meaning other space stations outside the Moon can also use CLT).

Don’t expect an app time zone and your favorite calendar has CLT as an option; NASA until the end of 2026 to establish CLT.

Why moon need time zonehimself?

In layman’s terms, we need a “time” ground synchronization system. moon” which is reliable due to the lower input pressure moon causing a slightly faster transit time there than on Earth – just 58.7 microseconds (1 million microseconds are in a second) faster than one second every 24 Earth hours.

It is not science fiction, although it is a main feature of Hollywood blockbusters like Interstellar. Known as “gravitational time compensation”, time displacement affects gravity.

Although small, this time difference can cause problems with the synchronization of satellites and space stations in orbit moon.

An unnamed OSTP official told Reuters: “Imagine if the world didn’t synchronize their clocks to the same time – how confusing it would be and how challenging everyday things would be. “

How do we know the internal time moon?

The Earth uses UTC or Coordinated Universal Time for synchronization time zone around the world. UTC is determined by more than 400 atomic clocks that are maintained in national “time laboratories” in approximately 30 countries around the world. Atomic clocks use atomic vibrations to achieve extreme precision in recording time.

A similar atomic clock will be installed moon to find proper time to read.

Known as Position, Address and Time (PNT), this precise timing system allows communication systems to accurately measure and keep time.

The Ordnance Survey, a British organization that has been making maps since 1791, explains that PNT has three main elements:

Positioning – the ability to accurately determine one’s position and direction, particularly two-dimensionally on a printed map, although three-dimensional orientation can be determined when necessary.

Navigation – the ability to determine the current position and the desired position (both relative and absolute), and apply corrections to course, direction, and speed to reach the desired position from anywhere in the world, from underground (below the Earth’s surface) to surface, and from surface to location.

Timekeeping – the ability to keep accurate and precise time from anywhere in the world.

Yes NASA have plans for time zone in other parts of space?

Although it hasn’t been mentioned yet time zone on another planet, in 2019, the Deep Space Atomic Clock (DSAC) mission. NASA testing atomic clocks to improve spacecraft navigation in outer space.

The DSAC mission with SpaceX’s Falcon Heavy rocket was launched on June 22, 2019. The rocket tested an atomic clock in Earth orbit for one year.

Normally, spacecraft keep accurate time by bouncing signals off the atomic clocks on Earth and then sending those signals back to the spacecraft.

In this mission, the atomic clock on board was tested to keep accurate time without relying on two-way communication between spacecraft and atomic clocks on Earth. Timing accuracy is related to getting the position right, while helping the spacecraft to successfully reach the desired location in space.

As described by the Jet Propulsion Laboratory NASAcenter for robotic exploration of the solar system: “A two-way system that sends signals from Earth to the spacecraft, back to Earth and then to the spacecraft again takes an average of 40 minutes.”

Imagine if the GPS on your phone took 40 minutes to calculate your location. You may miss a turn or exit several times on the highway before it catches up with you.

If people travel to the Red Planet [Mars]it would be better if the system was one-way, allowing researchers to determine their current position immediately rather than waiting for that information to come from Earth.

The mission ended successfully in 2021, with the atomic clock on board maintaining precise navigation time and position.
