    Lunar clockwork What scientists know for certain is that they need to get precision timekeeping instruments to the moon. kraken войти 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.” https://kra30c.cc kraken onion 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. kraken onion 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. https://kra30c.cc kra cc 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 12550 miles 20200 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.”

    ‘A whole different mindset’ Accurate clockwork is one matter. But how future astronauts living and working on the lunar surface will experience time is a different question entirely. kraken ссылка On Earth our sense of one day is governed by the fact that the planet completes one rotation every 24 hours giving most locations a consistent cycle of daylight and darkened nights. On the moon however the equator receives roughly 14 days of sunlight followed by 14 days of darkness. “It’s just a very very different concept” on the moon Betts said. “And NASA is talking about landing astronauts in the very interesting south polar region of the moon where you have permanently lit and permanently shadowed areas. So that’s a whole other set of confusion.” https://kra30c.cc kraken вход “It’ll be challenging” for those astronauts Betts added. “It’s so different than Earth and it’s just a whole different mindset.” That will be true no matter what time is displayed on the astronauts’ watches. Still precision timekeeping matters — not just for the sake of scientifically understanding the passage of time on the moon but also for setting up all the infrastructure necessary to carry out missions. The beauty of creating a time scale from scratch Gramling said is that scientists can take everything they have learned about timekeeping on Earth and apply it to a new system on the moon. And if scientists can get it right on the moon she added they can get it right later down the road if NASA fulfills its goal of sending astronauts deeper into the solar system. “We are very much looking at executing this on the moon learning what we can learn” Gramling said “so that we are prepared to do the same thing on Mars or other future bodies.”

    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.

    “You have a government that is reckless about what is going to happen to Guyana” said Melinda Janki an international lawyer in Guyana who is handling several lawsuits against Exxon. It’s pursuing “a supposed course of development that is actually backward and destructive” she told CNN. kelpdao And while plenty of Guyanese people welcome the new oil industry some say Guyana’s startling economic statistics do not reflect a real-world prosperity for ordinary people many of whom are struggling with the higher prices accompanying the oil boom. Inflation rose 6.6 in 2023 with prices of some foods shooting up much more rapidly. “Since the oil extraction began in Guyana we have noticed that our cost of living has gone sky high” said Wintress White of Red Thread a non-profit that focuses on improving living conditions for Guyanese women. “The money is not trickling down to the masses” she told CNN. CNN contacted President Ali the Ministry of Natural Resources and the Ministry of Finance for comment but received no response. Guyana a former Dutch then British colony which gained independence in 1966 is one of only a handful of countries that is a “carbon sink” meaning it stores more planet-heating pollution than it produces. This is due to its vast rainforest; trees remove carbon dioxide from the atmosphere as they grow. The country has protected its biodiversity where others have destroyed theirs President Ali said in a BBC interview last year. In 2009 the country signed an agreement with Norway which promised Guyana more than 250 million to preserve its 18.5 million hectares or nearly 46 million acres of forests. Ali insists the country can balance climate leadership and fossil fuel exploitation. The new oil wealth will allow Guayana to develop including building climate adaptations such as sea walls he has said. He has also pointed to the continued failures of wealthy countries already grown rich on their own fossil fuels to help poorer countries with climate finance. But there are concerns Guyana could fall victim to the “resource curse” in which vast new wealth ?can actually make life worse for those who live there.
