A human timekeeping system has been created on Mars.
The most used calendar on planet Earth is Gregorian calendarAnd puts us in 2021, the Mars calendar is much more recent, counting on Mars began in the first year, at the northern vernal equinox on April 11, 1955, a large dust storm erupted on Mars in the second half of that Mars year (sometimes called the Great Dust Storm of 1956) February 7, 2021 marks the beginning of the 36th year on Mars, Happy New Year on Mars.
The beginning of the calendar on Mars
Todd Clancy of the Space Science Institute was the first to describe a system for distinguishing the Martian years.
In a scientific paper published in the year 2000, it describes the changes in temperature over the The red planet, Foundations of the system in orbit to enumerate the Martian years and to aid in data comparisons.
In the years following Clancy’s research, other scientists also began using his own system for years MarsClancy and colleagues, especially those who study the Martian climate, described the choice of April 11, 1955, as “arbitrary,” but the great dust storm of 1956 – which fell on Mars in the first year – provides a suitable sign.
How much is a Mars year with respect to Earth
According to calculations by time organizers on Earth, the current New Year on Mars – Year 36 – begins on February 7, 2021, just like on Earth,
A year on Mars is defined as one orbit around the sun, The year of Mars lasts about two years from Earth (687 Earth days). And so the next Mars years will begin on December 26, 2022.
One year on Mars equals 687 Earth days, it takes twice the time it takes the Earth to revolve around the sun, this means that your age will be much less if you live on Mars, if you want to feel younger, just divide your current age by 1.88 And remind your friends that this is your true age on Mars.
Seasons on Mars
Mars has four seasons: Winter, Spring, Summer and Fall, Determined by the position of the planet along its orbit around the sun, the Martian new year begins with the northern equinox (northern spring, southern autumn), as Mars travels during its annual path, the axial tilt of the planet causes the northern hemisphere to receive more sunlight During the northern summer, the southern hemisphere receives more sunlight in the northern winter, just as it does on Earth.
The National Science Foundation (GBO) Green Bank Observatory, the National Radio Astronomy Observatory (NRAO), and Raytheon Intelligence & Space conducted a test in November to demonstrate that the new radio telescope system can capture high-resolution images in The space Near the ground.
GBO’s Greenbank Telescope (GBT) in West Virginia – the world’s largest fully steerable radio telescope – is equipped with a new transmitter developed by Raytheon Intelligence & Space, allowing it to transmit a radar signal into space, the long baseline array received Continent-wide (VLBA) in NRAO reflected signal and produced images of the Apollo 15 landing site on The surface of the moon.
And paves the proof-of-concept test, which has reached its climax
For two years, the way to design a stronger transmitter for the telescope, more power would allow the detection and imaging of small objects passing through the Earth, moons orbiting other planets, and other debris in Solar System.
Tony Beasley, Director of the National Observatory of Radio Astronomy and Vice President of Radio Astronomy at Associated Universities, Inc (AUI), said: “This project opens up a whole new range of capabilities for both NRAO and GBO, we have previously participated in important radar studies of the solar system, But convert GBT into a transmitter Radar My steerable planet will greatly expand our ability to follow
Interesting new search lines. ”
Using the information gathered in this latest test, the participants will finalize a plan to develop a high-power 500 kilowatt radar system that can photograph objects in the solar system with unprecedented detail and sensitivity. The increased performance will also allow scientists to Astronomy By using radar signals in distant places such as the orbits of Uranus and Neptune, which increases our understanding of the Solar System.
“The planned system will be a leap forward in radar science, allowing unprecedented features of the solar system to be accessed from here on,” said Karen O’Neill, Greenbank Observatory site director. Earth“.
Stephen Wilkinson, Principal Fellow of Engineering at Raytheon Intelligence & Space added: “Radar technologies from Raytheon could ultimately improve our ability to explore the solar system, allowing us to work with a community. astronomy Applying decades of radar know-how to a project that provides high-resolution near-Earth object imagery. “
