The Universe has been around for about 13.8 billion years, a very long time.
And the international space station is the greatest invention humans have ever created.
To believe that we are the only life forms in the Universe would be extremely naive.
We may be visited and watched secretly by other beings who share the Universe with us.
Who knows?
Recently, the International Space Station crew was about to capture what appeared to
be an alien spacecraft, but NASA quickly turned off its camera.
So, what are they trying to hide from the public, and why has NASA kept the secret visit
of flying objects in space to themselves?
Continue watching to the end to find out for yourself.
The ISS crew spends their days researching the biological and scientific effects and
how human life can be sustained in space for a long time.
Of course, as with any other human, astronauts must eat, bathe, and excrete waste during
their stay on the ISS.
That sounds strange, but how does that work in a zero-gravity environment?
This means that the gravitational pull of space does not push in any direction, which
is why anything that reaches space is always suspended in mid-air.
Let's discuss how the astronauts eat and bathe on the ISS.
The astronauts on the International Space Station do not bathe because the water will
not fall but will float in mid-air.
So astronauts clean their bodies with a wet towel and wash their hair with waterless shampoo.
Because water does not flow in zero gravity, astronauts cannot wash their hands under a
faucet as they would on Earth.
Because of that, there are no sinks or showers on board the space shuttle.
The bathroom is equipped with handholds and footholds to prevent astronauts from drifting
off in the middle of their activity.
They can sit or stand to pee, then press the funnel and hose against their skin tightly
so that nothing leaks out.
To poop, astronauts lift the toilet's lid and sit on the seat, just like on Earth.
However, because zero gravity would not allow their poop to enter the sink, a higher-density
liquid is used to push it down the waste sack.
Space station crews usually use sleeping bags in small crew cabins.
This is because each crew cabin can only accommodate one person.
At the end of each mission day, astronauts are scheduled for eight hours of sleep every
day.
With all these ridiculous conditions, can we say that astronauts are usually well-paid?
A civilian astronaut in 2020 can earn between $66,167 and $161,141 per year, according to
the US government's 2020 pay scales and a NASA job listing.
We are now in 2023, and we have no idea how much their paycheck will increase.
The station is a collaboration between several countries, including the United States, Russia,
Europe, Japan, and Canada.
Other countries, including Brazil, Italy, and China, also contribute to the ISS.
However, each country has its bases on the ISS.
So astronauts from different countries don't work together at the same base.
Though astronauts communicate and share experiment activities and specimens between the different
bases of each country.
How do astronauts get out of the ISS for spacewalks?
Before the EVA from the US airlock, the astronauts put on masks and go through a 'pre-breathe'
protocol in which they breathe pure oxygen to reduce the nitrogen concentration in their
blood.
They then suit up in the equipment lock with the assistance of one or two unsuited astronauts
while the suits are connected to power and oxygen.
The astronauts remove their suits from the airlock umbilicals and open the external hatch
door.
Then, they attach their safety tethers to the hatch's handrails and descend into the
void one after the other.
However, nothing compares to going outside for a spacewalk.
Nothing beats being alone in the Universe, opening the hatch, and pulling yourself outside
into the Universe.
The experience is similar to driving on a mountain road that is slippery and has a lot
of curves, and you can't really see anything because there is a cliff falling away on one
side and another cliff rising on the other.
But then you turn a corner and exclaim, "Oh wow!"
And there, in front of you, is the entire valley of the Universe.
If you're asking if astronauts can go outside the ISS, what it takes to get that approved?
It doesn't work that way.
But unfortunately, spacewalks or EVA are mission-critical activities.
They are only done to fulfill a mission requirement.
For example, something needs to be installed or removed, or it needs to be repaired.
These are the only reasons to engage in EVA.
It is too costly, resource-intensive, and dangerous to do for reasons other than mission
necessity.
The usual process for planning a spacewalk begins roughly eight weeks.
However, that schedule can be reduced to less than two weeks for a specific set of well-defined
contingencies.
First, we must determine what tasks we require the crew to perform, how they will perform
those tasks, what tools they will require, and what potential safety activities must
be performed.
What will the crew's translational path be, and whether or not new procedures will be
adopted?
This frequently includes having astronauts practice the planned activity in the pool
to identify risks and complexities.
Before spacewalks can be approved, several factors must be considered.
The first is Environmental Factors.
A thermal analysis of the worksite is required to understand the environment the crewmembers
will be exposed to.
In addition, the length of the ISS's day, and night cycle varies depending on the beta
angle.
Therefore, scheduling EVA during the long day is more efficient.
The next factor is; Suit Preparation.
No maintenance crew is on board to keep the suits and tools in good working condition.
Hence the crew must perform their tasks while inspecting their suits and tools to ensure
they are fully functional.
For instance, the space suit's batteries must be charged before the EVA.
During non-use, the batteries are kept discharged.
This reduces stress on the electrode-separator system and increases its lifetime.
The next factor is; Prebreathe
The pressure inside the suit is much lower than normal air pressure.
If the pressure of nitrogen in the blood is higher than the pressure of the air around
it, nitrogen bubbles can form and spread through the blood and tissues of the body.
This is called decompression sickness, which can cause various symptoms, from joint pain
to seizures.
Before going on a spacewalk, astronauts needs to spend some time breathing pure oxygen to
get rid of any nitrogen in their blood.
Let's now discuss more the objects seen flying toward the ISS, which NASA tried very hard
to cover up.
NASA has been accused of turning off the cameras on the International Space Station during
live streaming when the cameras showed something the space agency doesn't want you to see.
NASA is the only place that can talk about strange things that did not come from Earth.
But people have thought that the agency edits the information it gives to the public.
For example, a recent Skirmish made UFO fans think that NASA messed with a live broadcast.
A video clip shows an object entering the Earth's atmosphere.
Then, suddenly, NASA's live feed from the International Space Station cuts off the view.
In the video UFO Hunter Street cap one posted on YouTube, the bright object is seen coming
down toward Earth.
Then, the feed stops, but this doesn't stop the flow of information about one of the most
controversial topics ever.
No matter what NASA wants to do, it makes people more curious about UFOs because they
we want to know what the government is trying to hide from them.
For instance, UFO Hunter says it saw 10 UFOs during NASA's live stream from the ISS.
A man named Jeff saw ten unknown objects hovering around the International Space Station while
he was watching NASA's live feed.
Jeff put up a picture of the visual from when the ISS was over the South Atlantic.
He also sent this screenshot to a YouTuber named Michael, who calls himself a full-time
Earth Watchman.
An Earth Watchman keeps track of changes on and around Earth to find hidden reasons for
different things.
Since then, the screenshots have been seen by hundreds of thousands of people.
This event reminds us of the famous mental incident that changed how people talked about
UFOs for a long time.
But, unfortunately, it also had all the signs of an official cover-up at a time when it
was much easier to stop the flow of information.
But the most critical question is; why did NASA turn off the ISS camera from having a
clear view of these objects, and now the public is curious to know more?
And worse still, the public is curious about the destination of these objects, whether
the objects were sent from an alien world, which we humans have been guessing to exist
for a long while.
Will NASA later reveal the objects?
While they decide what to do, NASA is having huge trouble in launch tower in after launch
trial of his ship, what do they'll do to solve this?
