White House directs NASA to create a new time zone for the moon (2024)

White House directs NASA to create a new time zone for the moon (1)

The White House has tasked NASA with creating a new time zone for the moon by the end of 2026, as part of the United States' broader goal to establish international norms in space.

The direction to set up a lunar time zone comes amid growing global interest for humanity to establish a long-term presence on the moon in the coming years — a chief priority of NASA's Artemis program.

The new lunar standard, called "Coordinated Lunar Time (LTC)," is part of a broader effort to "establish time standards at and around celestial bodies other than Earth," according to an April 2 memo by the White House Office of Science and Technology Policy (OSTP). It was not immediately clear whether the moon would have multiple time zones, as Earth does.

"U.S. leadership in defining a suitable standard — one that achieves the accuracy and resilience required for operating in the challenging lunar environment — will benefit all spacefaring nations," the memo stated.

Because there is lower gravity on the moon than on Earth, time there moves slightly faster — 58.7 microseconds faster every day. Though minuscule, that difference would make it harder for the growing number of future missions to communicate with each other and for mission control to accurately track satellite and crew positions, among other issues.

"As NASA, private companies and space agencies around the world launch missions to the moon, Mars and beyond, it’s important that we establish celestial time standards for safety and accuracy," Steve Welby, the OSTP deputy director for national security, said in a statement.

On Earth, time is measured by numerous atomic clocks placed in various locations around our planet. A similar ensemble of atomic clocks on the moon itself may be used for lunar timekeeping.

"An atomic clock on the moon will tick at a different rate than a clock on Earth," Kevin Coggins, manager of NASA's Space Communications and Navigation Program, told the Guardian. "It makes sense that when you go to another body, like the moon or Mars, that each one gets its own heartbeat."

In space, there are a couple of different ways in which space agencies keep time. Astronauts aboard the International Space Station, which is in low Earth orbit, follow Coordinated Universal Time (UTC). For spacecraft elsewhere, NASA uses "Spacecraft Event Time" to catalog key mission events, like science observations or engine burns.

To establish LTC on the moon, the space agency told NPR that "subject matter experts throughout the international community are discussing an approach to provide recommendations to the International Astronomical Union for lunar reference frame and time systems."

NASA's Artemis program currently plans to send humans to the moon no sooner than September 2026, three months prior to the deadline to establish LTC. China previously announced a lunar crewed mission before the end of this decade and India by 2040.

    I heard about this a couple days ago while listening to the radio. Makes sense from a consistency perspective, but this sort of forward thinking will drive some bonkers.

    Scientifically, it makes good sense. But, I would not be surprised if it also becomes the butt of jokes. The derivation of "lunacy" makes the connection between the Moon and craziness. So, don't be surprised if we start getting derogatory comments like "He must be on Lunar Time to be thinking that."

    Why not give the whole moon one time zone? That zone would be Earth's incident zone.

FAQs

White House directs NASA to create a new time zone for the moon? ›

The White House has tasked NASA with creating a new time zone for the moon by the end of 2026, as part of the United States' broader goal to establish international norms in space.

Is the Moon getting its own time zone? ›

NASA has been asked to establish a unified standard time for the moon and other celestial bodies by the end of 2026. That request came from the White House – specifically the Office of Science and Technology Policy – on April 2.

Is NASA planning to make a moon base? ›

In 2028 NASA plans on launching the Lunar Surface Asset, a small habitat to the surface of the Moon on either an SLS Block 1B or through an Artemis Support Mission on a commercial launcher. This would be the first crewed lunar base.

Is 1 hour in space 7 years on Earth? ›

Is it true that one hour in space is 7 years on Earth? Generally, no. Different regions of space experience different degrees of time dilation, but the differences between most regions are negligible.

What is the new NASA mission to the Moon? ›

Artemis 3 (2026) is planned to be the first American crewed lunar landing since Apollo 17 in December 1972. The mission depends on a support mission to place a Starship Human Landing System (HLS) in a near-rectilinear halo orbit (NRHO) of the Moon prior to the launch of SLS/Orion.

Will the moon be in the same spot every night? ›

The way the Moon looks to us is continually changing. It moves across the sky rapidly over the course of a night. And from night to night it rises and falls at different times and in different parts of the sky.

Is the full moon at the same time around the world? ›

Are Moon phases the same everywhere on Earth? Yes, everyone sees the same phases of the Moon. People north and south of the equator do see the Moon's current phase from different angles, though.

Does the USA have a base on the Moon? ›

It took until 1969 before a man—astronaut Neil Armstrong—would take a giant leap for mankind on the surface of the Moon, but there is still no base of any kind on the Moon. While Project HORIZON is largely forgotten today, it remains an idea whose time simply never came—and a strange but true story in Army history.

Is China building a Moon base? ›

Pakistan and Belarus have come aboard the International Lunar Research Station (ILRS), a China-led project that will be constructed in the 2030s, if all goes according to plan. Belarus announced its involvement on Monday (Oct. 23), while Pakistan's became known late last week.

Why aren't we building a Moon base? ›

The type of rocket used to get the astronauts to the moon was an extremely powerful one called a Saturn V, which is no longer produced. This means that, at the moment, we do not have a rocket powerful enough to get people to the moon – let alone build a space station there.

Do you age in space? ›

Astronauts on the ISS experience both weaker gravity and higher velocity, resulting in slightly slower ageing compared to people on Earth. The European Space Agency (ESA) explained in a tweet that “after spending six months on the ISS, astronauts have aged about 0.005 seconds less than the rest of us.”

How long is 10 years in space on Earth? ›

You had the human made years in mind which belongs to Earth so that itself is your answer, 10 years in space is 10 years on earth as the quantity and measurement is done with same scale.

How long is 5 years in space on Earth? ›

Five years on a ship traveling at 99 percent the speed of light (2.5 years out and 2.5 years back) corresponds to roughly 36 years on Earth. When the spaceship returned to Earth, the people onboard would come back 31 years in their future--but they would be only five years older than when they left.

How many golf balls are on the Moon? ›

In the Apollo 14 mission in 1971, astronaut Alan Shepard decided to have some fun and knocked around a few golf balls which were then left on the moon once they went back home. Whether there's two or three golf balls on the moon is a hotly debated topic among moon-watchers but most believe that it is two.

How much do astronauts get paid? ›

According to NASA, civilian astronaut salaries are determined by the US Government's pay scales – or more specifically grades GS-13 to GS-14. As of 2022, the GS-13 pay scale ranges from $81,216 to $105,579 per annum. This is up to $8,798.25 per month or $50.59 an hour.

How many times has a human landed on the Moon? ›

There were six crewed landings between 1969 and 1972, and numerous uncrewed landings. All crewed missions to the Moon were conducted by the Apollo program, with the last departing the lunar surface in December 1972. After Luna 24 in 1976 there were no soft landings on the Moon until Chang'e 3 in 2013.

Why is time different on the moon? ›

Specifically, the moon's lower gravity and its motion relative to Earth cause time to pass around 56 microseconds faster each earth day. This 56 microseconds is not some abstract concept: Every day, astronauts living on the moon will age 56 microseconds more quickly than they will on Earth.

Does the moon set at the same time every day? ›

This means that the moon rises later and later each successive day, sometimes rising in the morning, sometimes in the afternoon, and sometimes at night. Similarly, the moon sets later each day, and can set at any time of the day or night, depending on where it is with respect to the sun.

Is time Longer On the moon? ›

Gravity on the moon is weaker than on Earth (think of astronauts bouncing effortlessly on the lunar surface). So lunar clocks will tick about 56 microseconds (0.000056 seconds) faster per day. This won't make much of a difference when astronauts plan their days.

Does the moon affect time? ›

The pull of the moon is also slowing the Earth's rotation, an effect known as tidal braking, which increases the length of our day by 2.3 milliseconds per century.
