Mars has remained in the human
imagination, and not even the rise of science and technology has interrupted
our wary fascination with this neighboring world. Telescopes in the 1880s
revealed strange markings on Mars which convinced masses of people that Mars
had canals built by an alien race. But today in this video we will discover the
10 interesting facts about mars.
Gravity on Mars is about 62% less
Than Gravity on Earth that is 3.711m/s2. That means if person on our
Earth weighs 100kg, it weighs 60kg on Mars. If we jump on mars we will reach 3
times more than taking jump on earth.
Mars has Largest and Long Lasting Sandstorms with enormous
power, they can last several months. “Every year there are some moderately big
dust storms that pop up on Mars and they cover continent-sized areas and last
for weeks at a time,” said Michael Smith, a planetary scientist at NASA’s
Goddard Space Flight Center in Greenbelt, Maryland.
When you think of a day, you normally think of one cycle of
daytime to nighttime. That is called a solar day. On Earth, a solar day is
around 24 hours. However, Earth’s orbit is elliptical, meaning it’s not a
perfect circle. That means some solar days on Earth are a few minutes longer
than 24 hours and some are a few minutes shorter. But On Mars, a solar day
lasts 24 hours, 39 minutes, and 35 seconds. Rounding that out, we say that a
day here on Earth works out to an even 24 hours while on Mars, a day lasts 24
hours and 40 minutes. That means if One Year on Earth was 365 days than on Mars
One Year Will be have 687 days.
The largest canyon in the Solar System cuts a wide swath
across the face of Mars. Named Valles Marineris, the grand valley extends over
3,000 kilometers long, spans as much as 600 kilometers across, and delves as
much as 8 kilometers deep. This Indicates that Mars used to have Long Rivers.
Mars is a harsh, cold world because it is about 227.9
million km away from the sun almost twice of distance between earth and sun. Mars's
atmosphere is about 100 times thinner than Earth's. Without a "thermal
blanket," Mars can't retain any heat energy. On average, the temperature
on Mars is about minus 60 degrees Celsius. NASA's Mars Curiosity rover measured
air temperatures as high as 6 degrees Celsius in the afternoon, with
temperatures climbing above freezing for a significant number of days.
Mars has two moon one is Phobos and other is Deimos. The
moons of Mars are so small that no detail can be seen with an Earth based
telescope. It was not until 1971 that the US Mariner 9 spacecraft obtained the
first images to show surface detail. Both moons are irregular in shape, and
have surfaces that are pockmarked by many craters. Phobos is the larger of the
two moons and is roughly an ellipsoid 19.2 by 21.4 by 27.0 km across its 3
axes. Deimos is about 11 by 12 by 15 km.
The Size of Mars is approximately 4220 Million Miles that is
almost twice smaller than our Earth which has about 7926 million Miles. This
can also be illustrates as, about Six Mars would take up to fill the volume of
Earth.
Scientist suggest that Mars was once like the earth but its
gravity captures several satellites that later crushed into mars causing to
cool down the core and thus Mars Stop spinning.
Right Now there are about seven robots that are roaming on
the surface on Mars, such as: Viking 1 with Viking 2, Pathfinder, Curiosity
Rover, Opportunity, Phoenix and Spirit, sent by different countries including
USA, USSR and China.
Mars has Largest Mountains of Solar system. Olympus Mons is
the largest volcano in the solar system. The massive Martian mountain towers
high above the surrounding plains of the red planet, and may be biding its time
until the next eruption. Olympus Mons rises three times higher than Earth's
highest mountain, Mount Everest, whose peak is 5.5 miles above sea level.
