Transcripts
Hello, friends!
On 11th April 1970,
a rocket launched for the Apollo 13 mission from Kennedy Space Center in America.
Three astronauts were on it,
going to the moon.
But the interesting thing was that
not even a year had passed since the day
when Neil Armstrong stepped on the moon for the first time.
This was already the third NASA mission
to send humans to the moon.
Seeing the success of the last two missions,
the astronauts in this rocket were very confident about their mission
and their dream.
Their dream was to set foot on the moon.
But at that time, they were unaware that
their dream would never come true.
In April 1970,
when their spacecraft was about 330,000 km away from the Earth,
they heard a loud bang, suddenly.
A huge bang that shook the entire spacecraft.
Within a few seconds, the warning lights and alarms start going on.
Loudly.
It was found that one of the oxygen tanks had burst.
And the other oxygen tank was leaking rapidly.
"Okay Houston, we've had a problem here."
"This is Houston, say again, please."
"Houston, we have a problem."
The mission control on the ground couldn't believe it.
They believed that the instruments were malfunctioning.
But the astronauts in the spacecraft could see through the window
that the air was leaking.
On the other hand, they see that because of the blast,
the spacecraft had shifted from its path so much that
it was going kilometres away from the Earth every second.
Within a few hours, the astronauts in Apollo 13
were so far away from the Earth that
it became a new record.
To date, no human has gone so far from the Earth
as these three astronauts did
during the Apollo 13 mission.
Forget landing on the moon,
the question back then was
whether they could return to Earth alive.
This is the distressing story of Apollo 13.
"Carbon dioxide levels in the module are rising.
"The crew were beginning to suffer.
It was a dire state.
It was a really, really emergency situation."
In 1961, American President John F. Kennedy
promised the world that
before the end of the decade,
he would have humans on the moon.
"...achieving the goal,
before this decade is out,
of landing a man on the moon,
and returning him safely to the Earth."
This promise should be seen in the context of the Cold War.
At that time, America and the Soviet Union were engaged in a race.
A space race.
Who will be the leader in the field of technology?
In 1969,
both Apollo 11 and Apollo 12 missions were successful.
Astronauts did not only step on the moon
but also safely returned to Earth.
Kennedy's promise was fulfilled.
But it had a side effect:
right after it, the people's and government's interest
in spending money on space
decreased drastically.
It's obvious that people were excited
to see a man step on the moon for the first time.
But people cannot be so excited for the second, third, and fourth time.
"The interest in the moon is fading fast.
People believed that Apollo 13
would just be another routine flight."
For this reason, the American government cut NASA's budget.
And many future missions that were planned for the new few years,
like Apollo 20, were cancelled.
That's why the Apollo 13 mission
came at a crucial time in the history of space travel.
NASA had to prove to the American government that
it was still worth spending money on space.
That's why the primary mission objective of Apollo 13 was
not only to inspect and survey the moon's soil
but to also develop the human capability
to work in the moon's environment.
"The main mission objective of Apollo 13
is scientific exploration of the moon.
We hope to find out a lot about the origin of the moon
and from that the origin of our own planet Earth."
The design of Apollo 13's spacecraft
was similar to that of the previous space missions.
Mainly, there were four main components
Command module, service module,
lunar module, and launch escape system.
The spacecraft was launched on a Saturn V rocket.
All three astronauts were seated in the command module,
which was the main part of the spacecraft.
But it was a small part.
The command module is just this cone shape
which is only 11 feet long
and has a diameter of 13 feet.
All the instrument panels, navigation gear,
radios, life support system,
and small engines were all in this command module.
The second most important part was the service module,
which had most of the oxygen for the astronauts.
It had some more engines too
and fuel cells to generate electricity.
The command and service module is often
collectively called the command and service module
or CSM in short form.
They are connected during the entire mission
until the astronauts return to Earth.
And only during the re-entry to Earth
are they separated from each other.
The third part was the lunar module,
which was actually supposed to land on the moon.
And once the work on moon was over,
it was supposed to get attached to the CSM module once again.
The fourth part, the Launch Escape System,
was not so important for the mission.
Its only task was to protect the astronauts from an accident during the launch.
It works like this.
If there's an accident during the rocket launch,
and the rocket catches fire,
it safely ejects the astronauts
and takes them away from the accident.
You can see in this video,
where this abort system was being tested.
But if everything goes well in the launch,
then the LES is not needed
and it is ejected and thrown away.
On 11th April 1970,
since Apollo 13 launched safely and successfully
the LES was not needed.
3 astronauts were on the spacecraft.
Commander Jim Lovell,
the pilot of the Lunar Module, Fred Haise,
and the third, pilot of the Command Module, Jack Swigert.
Coincidentally, according to the original plan,
none of these three were chosen for this mission.
Originally, three different astronauts were chosen for this mission.
But they all had different problems because of which
they were not able to participate in this mission.
For this reason, the crew of these three astronauts takes off from the Earth.
To see this rocket launch
there were around 200,000 spectators on the ground.
This was a small number
compared to the Apollo 11 lift-off the previous year.
That had 7 million spectators for the rocket launch.
NASA again realized
how quickly people lost their interest in space exploration.
But if we talk about the mission,
this spacecraft took off smoothly towards its destination.
It was supposed to take 3 days for them to reach the Fra Mauro crater of the moon.
This is a big hole on the moon's surface.
A crater.
Which is believed to contain a lot of information
not only about the moon but also about the Earth.
The biggest problem during the first 2 days of the flight was when
astronaut Jack Swigert realized that
he had forgotten to file his income tax return.
He asked the mission control on Earth
whether he could get an extension.
He got a good-humoured reply that
that he could get a 60-day extension.
This conversation proves that
everything was going right.
During the first two days, there were no problems in the mission.
At 46 hours 43 minutes of the mission,
the capsule communicator on duty at that time said that
the spacecraft was in a good shape
and that they were bored sitting there.
"This is Apollo Control at 46 hours, 43 minutes."
"Spacecraft is in real good shape as far as we're concerned, Jim.
We're bored to tears down here."
Things were going so smoothly that
people were getting bored.
By the way, you will feel very strange to hear this,
but intentionally giving yourself time to get bored
is a good habit, in my opinion.
I believe that if you want to maximize your productivity and creativity,
then you have to leave sometime free during the day.
A timewhen you are literally doing nothing,
just getting bored.
This is very important to relax the mind,
especially in today's world.
If a person gets bored for 5 seconds,
he starts scrolling through his phone.
This is the big secret
as to how I can manage my time so efficiently
and consistently manage to give you so many videos.
And that too while continuously travelling.
I have shared many more such secrets and practical tips
in my time management course.
A course that gives you step-by-step solutions
on how you can take out more time for things in your life
and maximize your productivity and creativity.

Now let's get back to the topic.
The third day of the mission,
13th April,
the crew is told that
they have to do some tests on the lunar module.
And apart from this,
they have to do a broadcast for the television.
Where they will use the cameras
to show the interiors of the command module and service module to the world.
Now the audience's interest in this was so low that
no television network showed this broadcast at that time.
Commander Lovell's wife
went to the VIP section of the mission control to watch this broadcast.
About 6 and a half minutes after the end of the TV broadcast,
the flight controllers on the ground
asked astronaut Swigert
to check the oxygen level.
There was nothing unusual in this.
It was just a routine check of the oxygen tanks in the service module.
And while this check was being done,
suddenly, a huge explosion occurred.
Many warning lights and alarms went off.
As I told you at the beginning of the video,
the astronauts in the spacecraft were largely in shock.
Commander Lovell contacted Mission Control and said,
"Houston, we've have had a problem."
It turned out that one tank of oxygen was completely empty
and the oxygen level in the other tank was going down rapidly.
Mission Control on the ground first thought that
the instruments must be showing the wrong data,
but that was the truth.
Everyone needed to take action urgently
if they wanted to save the lives of these astronauts.
The TV channels that had called this mission boring
and were not showing it on the news
made this the news headlines suddenly.
"Apollo 13 to the moon
is in serious jeopardy this morning.
And it is not going to make a moon landing."
The oxygen tanks in the spacecraft
were sphere-shaped.
In these, oxygen was stored in liquid form.
There was a heater at the center
which converted the liquid oxygen into gas.
On Apollo 13, there were two such tanks in the service module.
The tank number 2
was originally installed in Apollo 10
but was removed from there for modification.
And a minor accident happened with it.
It accidentally fell down during repair
and was damaged.
The tube inside it was damaged
but no one saw it during the inspection.
While testing it,
people noticed that the tank
would not be completely empty.
To get rid of the remaining oxygen,
heaters were used to boil it completely.
Later, it was found that the thermometer inside it
could show a maximum temperature of 30°C.
But when the heater was used to heat the oxygen in the tank,
the temperature would reach as high as 538°C.
No one noticed this extreme heating
because it did not register in the thermometer.
Due to this extreme heating,
the insulation of the electrical wires in the tank were damaged.
Before the mission, NASA's managers and engineers
had approved the tank after a thorough investigation
but they were unable to see the internal damage.
And because of this,
during the Apollo 13 mission
during the routine check of the tank on the third day
due to those electric wires,
there was a spark and the tank explodes.
It was only by chance that the tank was attached to the exterior of the spacecraft.
Had it been attached inside the spacecraft and exploded there
then all the astronauts would have been k!lled instantly.
But because it was on the outside,
the explosion occurred outside.
And only a 13-foot panel was damaged in the service module.
What else was damaged in the spacecraft?
The astronauts were not so sure.
Now everyone had to make an important decision.
Which way could they take to return to Earth?
The fastest way to return to Earth was to
rotate the spacecraft.
But to do this,
the main engine of the service module had to be started.
The main engine was located near the blast in the CSM module.
No one knew whether the engine was damaged or not.
The second way to return to Earth was to
go towards the moon
and circle around the moon
to return to the Earth.
For this, the engine of the service module would not be required.
But the risk was that
it would take 4-5 days to return to Earth.
Did the astronauts have enough oxygen and water left?
NASA's flight director chose the second option.
To take the long way back.
The astronauts were told to shut down the CSM module immediately.
And while returning,
they were told to use the lunar module as a lifeboat.
Though this decision was a safe option, it did have several problems.
The lunar module was designed in such a way that
only two astronauts could sit in it
for about 20 hours.
Because as I told you,
its original purpose was to land on the moon
and get attached to the CSM module again.
But now, it was expected that
these three people would sit in the lunar module
for 4-5 days.
The engines of the lunar module were not designed in a way that
they could be fired repeatedly.
To a large extent, this was also a risky manoeuvre.
To conserve supplies and energy,
the astronauts were told to shut down all non-essential systems in the spacecraft,
including the heaters that were installed.
It was very important to save electricity.
As per this plan, the astronauts sat in the Lunar Module
and for the first time, the engines of the Lunar Module were fired.
When an engine is started, it is called a Burn.
So, they do the first Burn
to get on the new path.
With the help of this burn,
they reached the other side of the moon.
The far side of the moon.
They became the first humans in the world
to go so far from the Earth.
And this record remains unbeatable even now.
At their furthest point, they were 400,000 km away from the Earth.
If they stayed on this path,
they could reach the Earth about 153 hours after launch.
But this time margin was very risky.
If they reached Earth after so long,
then only 1 hour of surplus food, water and oxygen would remain for the astronauts.
NASA team on the ground believed that this margin is very narrow.
That's why the astronauts were told to
burn the lunar module engine for the second time.
The engineers in the mission control had done many calculations
to find out whether the lunar module engine
will be able to handle the second burn or not.
These calculations proved correct
when the second burn is done,
the flight time of 153 hours
was reduced to 143 hours.
An 11-hour long margin of survival.
Before the astronauts could relax,
another problem arose.
The high concentration of carbon dioxide.
In spaceships, apart from oxygen tanks,
there are canisters of lithium hydroxide to remove carbon dioxide.
When astronauts breathe in oxygen,
they breathe out carbon dioxide.
If that carbon dioxide is not removed,
it will result in a large amount of carbon dioxide which can be problematic.
That is why canisters of lithium hydroxide are used
so that carbon dioxide reacts with it
and becomes lithium carbonate.
But the problem here was that
the canisters of lithium hydroxide in the lunar module
were enough for only two people to survive for 2 days.
But here, there were 3 people
who wanted to survive for 4 days.
The good thing here was that
there were some canisters in the command module too.
But their filter was square
and the ones in lunar module had a circular shape.
The experts on the ground had 24 hours to solve this problem.
Astronauts from the spacecraft communicated to tell them
about all things present around them.
Plastic bags, cardboard, some suit hoses, some duct tape,
They wanted to create something that could be the solution to this problem.
After a few hours of experimenting,
they make a contraption to make this work.
After giving step-by-step instructions,
a new device was created with the things present there,
with which the level of carbon dioxide decreases again.
Commander Lovell in his book Lost Moon states that
"the contraption wasn't very handsome, but it worked."
The thing they made looked like this.
In this entire rescue mission, even the smallest details were taken care of.
Astronauts were instructed
not to drink more than 200 ml of water in a day.
Because if they drink more water,
they will need to ur!nate.
And in this way, the quantity of their ur!ne
could change the direction of the spaceship.
That's why they needed to survive by drinking so little water.
These 3 astronauts lost 14 kgs of weight in total.
Astronaut Haise gets a urinary tract infection.
After 4 days, when Apollo 13's spacecraft reaches Earth,
astronauts realize that they need to burn once more.
In their calculations,
they hadn't taken into account the cooling vapour present in the spacecraft.
This caused the spacecraft to wander off the track.
Commander Lovell carried out another burn of the lunar module
which brings the spacecraft back on track.
Thankfully, the spacecraft could withstand the third burn too.
Even though this lunar module was designed to withstand only one burn.
The whole world was holding their breaths and watching the news channels.
And were waiting for the astronauts to return to Earth.
The family members and friends of the astronauts
were watching this play out on TV together.
Now the biggest question was
when this broken spacecraft enters the Earth's atmosphere
will the spacecraft be about to sustain the heat impact?
Will the astronauts be able to survive?
For this part, the astronauts had to return to the command module
because only the command module was made for re-entry on the Earth.
As soon as the command module entered the Earth's atmosphere
there was a communication blackout.
This was normal because
due to ionization of the air,
the radio waves get blocked
and communication cannot be done
between the NASA employees present on the ground
and the astronauts in the spacecraft.
Usually, this communication blackout is for 2 to 3 minutes.
It was expected that the communication blackout here
would be for a maximum of 3 minutes.
3 minutes were over,
but there was no answer from the other side.
10 seconds pass.
30 seconds.
60 seconds.
Even after 4 minutes,
there was no communication from the spacecraft.
Could the astronauts survive or not?
4 minutes and 27 seconds later,
finally, communication was received from the other side.
The people watching it on television could finally breathe again.
All three astronauts survived.
The parachute was deployed in the command module
and it slowly fell into the Pacific Ocean.
"Teamwork was necessary.
Good leadership.
Initiative to think outside of the box.
When things go wrong,
how do we repair them?
Those are the three things
that were absolutely necessary."
The three astronauts return home safe and sound.
Although this mission failed,
none of the three astronauts set foot on the moon.
But still, this Apollo 13 mission
made its mark on the pages of history.
Showing this historical rescue mission of the Apollo 13
and the bravery of the astronauts.
Several books are written on it
and films are made.
After the investigation of this incident,
many safety measures are adopted by NASA.
So that there could be no such accidents in future missions.
After Apollo 13,
Apollo 14, Apollo 15,
Apollo 16, and Apollo 17
all these missions were successful.
On 7th December 1972,
Apollo 17 was the last mission
by NASA under the Apollo program.
The astronauts in this mission spent 3 days on the surface of the moon.
And this was the last time till today
when humans went to the moon.
What is the reason behind this?
You will get the answer to this question in my Apollo 11 video.
In that video, I discussed Neil Armstrong's mission.
You can click here to watch it.
Thank you very much!
