Lunar clockwork
What scientists know for certain is that they need to get precision timekeeping instruments to the moon.

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.

“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.”

Atomic clocks, Gramling noted, are great for long-term stability, and crystal oscillators have an advantage for short-term stability.
“You never trust one clock,” Gramling added. “And you never trust two clocks.”

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.

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.

But, Patla said, you get what you pay for.

“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.”

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.

(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.”)

Space, time: The continual question
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.

To add more complication: Time also passes slower the faster a person or spacecraft is moving, according to Einstein’s theory of special relativity.

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.

For other missions — it’s not so simple.

Fortunately, scientists already have decades of experience contending with the complexities.

Spacecraft, for example, are equipped with their own clocks called oscillators, Gramling said.

“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.”
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.

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.

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.

“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.”

Свято електронної музики цього року вразило гостей своєю концепцією. Виступи Solomun і Peggy Gou задавали тон вечора, створюючи унікальну динаміку на танцполі. Інтерактивні світлові ефекти і дзеркальні декорації перетворили простір на фантастичну сцену, а зони відпочинку були справжньою оазою для гостей, які потребували відновлення сил.

The voice of ‘White Lotus’ star Walton Goggins is the lullaby we didn’t know we needed
jumper exchange
While his “White Lotus” character Rick has been the source of some stress this season, Walton Goggins is here to soothe us into a state of dreamy sleep to make up for it.

The actor has partnered with relaxation and meditation app Calm for one of their famed Sleep Stories, lending his smoky voice to a fable titled “The Yard Sale.”

Goggins announced the Sleep Story on his verified Instagram on Tuesday, writing, “A friend once said to me the first question you ask someone shouldn’t be, ‘How are you?’ but rather, ‘How did you sleep last night?’ I agree.”

The post included an excerpt from the story, in which Goggins is heard languidly instructing listeners to relax their bodies and get into bed. “You could even climb into a hammock,” he added. “I wouldn’t do that because I’ve never gracefully got in or out of one.”

In the caption, the actor also wrote that he “wanted to create a Sleep Story that feels dreamlike, helping people slow their minds down by wandering through a yard sale (which happens to be one of my favorite things to do), uncovering hidden treasures.”

“It’s the Walton Goggins version of counting sheep. I hope you enjoy,” he added.

Other celebrities who have read bedtime stories in the hopes of putting audiences to sleep include Dolly Parton and the late Jimmy Stewart, whose voice was featured in a Calm Christmas Sleep Story in 2023 thanks to generative AI technology.

Goggins currently stars on “The White Lotus,” where his character is often the most stressed out and tortured of the ensemble, at one point setting a slew of snakes free.
