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

    ‘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 официальный сайт 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 войти “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.”

    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. кракен онион 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 Кракен даркнет 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.”

    “Every morning I come downstairs and he’s already done the dishwasher he’s already packed his lunch and he’s ready to go” Ruthe’s father Ben tells CNN Sports. “He’s just a disciplined kid. He goes to bed early he looks after himself he eats well he looks after his sister. He’s just a good kid around the house in all ways really. We’re very lucky.” pendle finance Ruthe is next due to compete in the 1500 meters at the Maurie Plant Meet in Melbourne on Saturday and one target time to aim for will be his dad’s fastest time of 3:41.22 – three hundredths of a second faster than Ruthe’s current personal best. But he still has a way to go before he can call himself the most decorated runner in his family. Dad Ben and mom Jess are both former national champions who represented New Zealand on the world stage while his maternal grandparents won European championship medals for Great Britain. His grandmother Rosemary Stirling arguably had the most impressive achievement: an 800m Commonwealth Games title from 1970. Despite his family pedigree Ruthe was never under any pressure to take running seriously. His parents in fact didn’t allow him or his sister Daisy to train at all until they were 13 never wanting their identities to be tied solely to running. “It feels like it’s the right decision about now” says Ben. But as he gradually starts to realize his potential Ruthe when pushed admits to having big goals in the sport. “If I had to pick one thing definitely Olympic gold” he says. “I feel like that’s most runners’ dream and the biggest thing you can actually win. So that’ll definitely be the top of my bucket list.” The 2032 Olympics in Brisbane Ruthe adds would be a nice target. And as for the Los Angeles Games in three years’ time? “I’d actually love to try and qualify for LA 28” he says. “I feel like that’ll be a tough goal. But if I do that I’ll be really happy.” Already Ruthe’s name is being mentioned in the same breath as Norway’s Jakob Ingebrigtsen the most successful middle-distance of this generation. It was his record as the youngest-ever four-minute miler that Ruthe took last week and the New Zealander also beat Ingebrigtsen’s 1500m record for a 15-year-old earlier this year. Ingebrigtsen’s success Ruthe says has given him hope that he too can “have a good future” in the sport. But his biggest source of motivation comes not from the two-time Olympic champion but from those closest to him – his training group led by coach Craig Kirkwood and athlete Sam Tanner. The pair were instrumental in Ruthe’s recent mile time of 3:58.35 and it was five-time national champion Tanner who paced him perfectly around four laps of the track on his way to the record.

    Aged 15 New Zealander Sam Ruthe has already run a four-minute mile. He would ‘love to try and qualify’ for the 2028 Olympics paraswap Sam Ruthe had the eyes of thousands on him when he stepped onto a running track in Auckland just over a week ago. Undaunted by the occasion Ruthe went on to become the first 15-year-old to run a sub-four-minute mile even managing a nonchalant shrug of the shoulders as he crossed the finish line. The race was almost entirely engineered for the high school student to break the fabled four-minute barrier – a feat first achieved by Roger Bannister more than 70 years ago – but the weight of running history was a burden that Ruthe seemed to bear lightly. The first three laps he later said in a video documenting the race “felt pretty comfortable – nothing too crazy.” Perhaps the most intimidating part of his achievement occurred when Ruthe returned to school the next day only to be immediately called into the principal’s office. “He’s like ‘Alright so you’re gonna have to go up on stage and we’ll get the whole school to clap you’” Ruthe tells CNN Sports’ Patrick Snell. “It was really scary actually. I headed into class and everyone thought I was famous.” It’s easy to forget given his history-making performance last week that Ruthe is like most other 15-year-olds in New Zealand. He goes to school spends time with his friends and helps with chores around the house. He also just happens to be one of the most exciting middle-distance runners on the planet one of the latest star athletes to emerge from sports-mad New Zealand.

    Tyler O’Neill hits record-extending sixth straight Opening Day home run orbiter For six seasons in a row Tyler O’Neill has homered on MLB Opening Day. Making his debut for the Baltimore Orioles on Thursday O’Neill started the season with his record-extending sixth straight home run on Opening Day during his team’s 12-2 win against the Toronto Blue Jays. No other player has homered on more than four consecutive Opening Days with the 29-year-old outfielder’s three-run shot sending the Orioles into a 5-0 lead at the top of the third at Rogers Centre. Todd Hundley 1994-97 Gary Carter 1977-80 and Yogi Berra 1955-58 all hit four consecutive home runs on Opening Day while the Major League Baseball record for the total number of Opening Day home runs is held jointly by Adam Dunn Ken Griffey Jr. and Frank Robinson on eight. “I’m just not trying to make too much of it” O’Neill told reporters about his streak. “I’m just trying to go out have a good first at-bat and see what the game gives me from there. “Obviously I understand what’s going on but it’s not like I’m going out there trying to do anything crazy.” O’Neill who signed a three-year 49.5 million contract to join Baltimore from the Boston Red Sox in the offseason finished three-for-three with three RBIs and two walks against the Blue Jays. “It’s a little different when the lights turn on and you’ve got to show up so it was really cool to see all the guys show up today” he said. “We got after it out there.” While the first two games of the MLB regular season took place between the Chicago Cubs and Los Angeles Dodgers in Tokyo last week Thursday marked the first official day of the season in the United States.
