大家好 我是Mike Chang
Hey guys, this is Mike Chang.
Among the many many mysteries of the universe
is the one that concerns the discovery of a deep hole
in the surface of the red planet or Mars.
And this was something NASA’s multi-purpose spacecraft
Mars Reconnaissance Orbiter MRO spotted
while capturing snapshots of the planets South Pole.
Now take a look at this.
The fact that this enormous crater is the first
one of its kind to show up in the last 11 years
that MRO has been exploring Mars,
ever since it attained the Martian orbit in March of 2006
it’s what makes this revelation such a baffling one.
So here’s what the photograph reveal.
MROs high-resolution imaging science experiment camera or HiRISE camera
boasts a high resolution of 1 microradian
or 0.3 meters at an altitude of 300 kilometers.
What that means is that the high-tech camera
enables researchers to capture detailed images of objects.
Approximately 3 feet or a meter plus in dimension
from an elevation of 200 to 400 kilometers.
This further implies that the recently discovered pits on Mars
is by no means a small one.
In fact, it is estimated to be quite vast
with hundreds or even thousands of feet.
So much so that it comes across is so big that researchers think that
it resulted from maybe a massive collapse or a humongous hit.
Also just taking a look at the surface of Mars for a moment here.
Mars exhibits an iron oxide on its surface,
that’s characterized by the presence of several impact craters in depressions.
This is apart from the presence of valleys deserts and polar ice caps
the planets rocky surface is attributed to a plethora of reasons.
Such as continual meteorite impacts, collapsing lava tubes
blowing water in the early days and volcanic activity.
However, none of these explanations really seems to hold ground.
When it comes to deciphering
as to what could have led to the creation of this
strange deep hole in Martian surface.
Also taking a look at the composition
of the deep hole from the image taken by MRO.
It appears that the newly discovered crater is
much much deeper than the other craters.
They are commonly cited on the surface of our solar system’s second smallest planet.
Also researchers spotted a gleam of ice
at the bottom of this vast pit of melting frozen carbon dioxide.
In apart from the pit itself.
Astronomers witnessed patches of frozen carbon dioxide
dotting the ice-covered area around the hole.
These circular patches are thought to be the regions
where dry ice or frozen carbon dioxide had its sublimed own way
under the heat of the summer sun at Mars’ south pole.
Basically, this whole area is kind of looks like a Swiss cheese.
That’s why astronomers call it the Swiss cheese terrain.
So basically there are a lot of craters on Mars.
But no one really has a clue as to
how this this massive and deep of one was created.
But there are efforts right now to narrow down the possible causes
that could have led to this formation.
Of course, alien war would not be considered,
but till such time NASA comes up with a convincing theory.
The origin of this deeper than the average depression
will remain a guessing game for all.
So take your best guess what do you think caused us
massive deep hole on the surface of Mars.
Let me know your thoughts in the comments below.
Thanks so much for watching, I’ll see you later.
