The earth is spinning faster than it should and no one knows why



The earth is spinning faster than it should and no one knows why

If you feel like the days are getting shorter with age, you have no idea.

On June 29, 2022, the Earth completed an orbit that took 1.59 milliseconds less than the average day length of 86,400 seconds or 24 hours. While the 1.59ms drop may not seem like much, it is part of a larger, odder trend.

In fact, on July 26, 2022, another new record was set. O Determined when the Earth ended her day 1.50 milliseconds shorter than normal, as I mentioned earlier. look out for and time tracking website hour and date. The time and date indicate that 2020 had the fewest days since scientists began using atomic clocks for daily measurements in the 1960s. Scientists started noticing this trend in 2016.

While the average length of a day may vary slightly in the short term, the length of the day has been increasing in the long term since the formation of the Earth-Moon system. This is because, over time, the force of gravity has transferred energy from the Earth through the tides to the Moon, pushing it slightly away from us. Meanwhile, since the two bodies are in a tidal state – meaning that the rate of rotation and rotation of the moon is such that we only see one side of it – physics dictates that Earth’s day must be extended in order for the two objects to remain in a tidal cycle. . When the moon is gone. Billions of years ago, the Moon was much closer, and the length of the Earth’s day is much shorter.

While scientists know that Earth’s days are getting shorter in the short term, the exact reason for this remains unclear — beyond the impact it could have on how we humans keep track of time.

“The rate of rotation of the Earth is a complex issue. This is due to the exchange of angular momentum between the Earth and the atmosphere, the effects of the ocean and the influence of the moon,” said Judah Levine, a physicist in the National Institute of Standards and Technology’s Department of Time and Frequency. Discover the magazine. said. “You can’t predict what will happen very far into the future.”

But Fred Watson, an Australian traveling astronomer, For ABC News in Australia that if nothing is done to stop it, “the seasons will gradually move out of the seasons of the calendar”.

“When you start looking at real details, you realize that the Earth is not just a solid spinning ball,” Watson said. “It’s liquid on the inside, it’s liquid on the outside, it has an atmosphere, and all these things rotate a little bit.”

Matt King of the University of Tasmania described the trend to ABC News Australia as “definitely bizarre”.

“Obviously something has changed, and changed in a way that we haven’t seen since the advent of precision radio astronomy in the 1970s,” King said.

Could this be due to extreme weather conditions? As I already noticed look out forNASA says Earth’s rotation could be slowed down by strong winds During El Niño years, this deceleration of the planet’s rotation. Similarly, the melting of the polar ice caps moves matter around the Earth and therefore can change the rate of rotation.

While this simple time absorption has little effect on our daily lives, some scientists are calling for the introduction of a negative “leap second” that would subtract a second from a day to keep the world on track to an atomic time system if the trend continues. Since 1972 leap seconds have been added every few years. The last one was added in 2016.

“It’s very likely that a second negative hop will be needed if the Earth’s rotation continues to increase, but it’s too early to tell if that will happen,” said physicist Peter Wibberley of the UK’s National Physical Laboratory. Telegraph. “There are also international discussions about the future of leap seconds, and it is also possible that the need for a negative leap second could lead to a decision to permanently abandon leap seconds.”

‘My power is really low’: NASA’s Mars Insight rover prepares to launch from the Red Planet



NASA Lander InSight He has delivered what may be his last message from Mars as he embarks on a historic mission to uncover the secrets of the Red Planet’s interior.

In November, the space agency warned that the probe could be running out of time as dust continued to condense and stifle InSight’s power.

“Spacecraft power generation continues to decline as windblown dust accumulates on solar panels,” NASA said in a statement. Update November 2. “The end is expected to come in the coming weeks.”

message shared NASA The InSight Twitter account tweeted on Monday: “My power is very low so this might be the last photo I can upload. Don’t worry about me: my time here has been productive and uneventful. If I can keep talking to my mission team, I will—but I will.” Subscribe here soon. Thank you for staying with me.”

My power is very low, so this might be the last photo I can upload. But don’t worry about me: my time here has been productive and uneventful. If I can keep talking to my mission team, I will, but I’ll sign here soon. Thank you for staying with me.

A geologist robot armed with a hammer and a seismograph first reached the barren expanse of Elysium Planitia in November 2018.

Since then, she has carried out geological excavations, taking the first measurements of earthquakes with a high-tech seismometer placed right on the surface of Mars.

Last month, the solar-powered car released an update to remind us of its time in space.

“I was lucky to live on two planets. Four years ago I made it safely to the second one, much to the joy of my family at first. Thanks to my team for taking me on this journey of discovery. I hope I can be proud of you.”

According to the published mission, Insight has measured more than 1,300 seismic events since it was published, and more than 50 of them had signals clear enough for the team to extract information about their location on Mars. Results.

The probe’s data also provided detailed information about Mars’ interior, liquid core, surprisingly variable remnants beneath the surface of an extinct magnetic field, climate and seismic activity.

old for Its launch in 2018NASA Chief Scientist Jim Green said the mission was “fundamental to understanding the origins of our solar system and how it became what it is today.”

NASA will not declare the mission complete until Insight confirms the arrival of two spacecraft orbiting Mars that are relaying their information back to Earth.

In 2018, the veteran rover announced the capabilities end of his 15 year stay Sending an incomplete photo of the Valley of Perseverance.

A severe dust storm darkened the sky around the solar-powered rover, shattering the sun and leaving behind a dark image with white spots due to camera noise. The transmission is interrupted before the complete image can be transmitted.
