play00:00

Hello, friends!

play00:01

5th June, 2024,

play00:02

at 10:52 AM,

play00:04

a Starliner spacecraft was launched in America.

play00:14

It was carrying two experienced astronauts from NASA.

play00:17

Commander Barry E. Wilmore and Pilot Sunita Williams,

play00:20

they were going on a small trip to the International Space Station.

play00:25

The spacecraft they were travelling in,

play00:27

Starliner is a bit special.

play00:30

It was built by a private company,

play00:32

Boeing.

play00:32

The same company that makes aeroplanes

play00:34

and recently, many of those aeroplanes crashed.

play00:39

This Starliner spacecraft

play00:40

is still in the developing stage.

play00:42

And this particular mission

play00:43

was the last step to test the capabilities of the Boeing Starliner.

play00:48

That's why this mission was literally named

play00:50

Boeing Crew Flight Test.

play00:52

The next day, after 27 hours,

play00:54

at 1:34 PM,

play00:56

this spacecraft begins docking at the International Space Station.

play01:04

It was a successful docking.

play01:06

And after some time, both the astronauts happily

play01:09

enter the Space Station.

play01:10

Look at this video.

play01:12

Pilot Sunita Williams was so excited while entering.

play01:17

This successful docking meant that

play01:18

Boeing became the world's second private company

play01:21

to make and fly a human orbital spacecraft.

play01:24

Before this, only SpaceX had done this.

play01:27

To date, only 3 countries have been able to do this.

play01:30

Russia, the USA, and China.

play01:32

But the celebration for this good news

play01:34

could not last long.

play01:35

This Starliner mission was supposed to last only 8 days.

play01:38

These astronauts had to return to Earth after 8 days.

play01:42

But today, even after 3 months,

play01:44

both these astronauts are stuck in space.

play01:48

There are many problems with this spacecraft

play01:50

because of which it cannot be used again.

play01:52

According to NASA,

play01:53

these astronauts will remain there for 8 months.

play01:57

How did this failure happen?

play01:58

How much can we blame Boeing?

play02:00

Let's understand this situation

play02:02

in this video.

play02:12

Before starting the video, it is important to clear one thing here

play02:14

that though both of these astronauts are stuck in space

play02:17

they are not in any kind of danger.

play02:19

The International Space Station is more than 350 feet long end to end.

play02:23

It can accommodate many people.

play02:25

The living and working space on the ISS,

play02:28

is bigger than a 6-bedroom house.

play02:30

There's space for 6 people to sleep on the ISS.

play02:32

There's enough food, water, clothes, and oxygen supply system.

play02:36

There are two bathrooms,

play02:37

a gym, and a 360° view bay window.

play02:40

Although it is not a luxury hotel,

play02:43

it is a good place to stay comfortably and survive.

play02:47

The ISS has its own oxygen-generating system

play02:50

which generates oxygen through the electrolysis of water.

play02:53

It also recycles oxygen.

play02:56

When we exhale,

play02:57

we release a high quantity of carbon dioxide,

play03:00

as well as oxygen to some extent.

play03:02

So, being able to extract that oxygen

play03:05

recovering it and using it again,

play03:08

it can do that.

play03:09

Similarly, there is an excellent recycling system for water too.

play03:12

Urine is recycled into drinking water.

play03:17

Apart from this, the water recycling system

play03:19

can also capture all traces of moisture

play03:22

that is released as breath or sweat.

play03:25

And in terms of food,

play03:26

the ISS carries food reserve for 6 months.

play03:30

And in every 5-6 months,

play03:32

the crew members on the ISS keep rotating.

play03:37

Right now, the crew members of Expedition 71 are in the ISS.

play03:40

The video you saw earlier

play03:42

in which Sunita Williams was excitedly entering the ISS,

play03:45

in that video, you can see other astronauts

play03:47

they are a part of the Expedition 71,

play03:49

and were already living in the ISS.

play03:51

These 4 astronauts are from NASA,

play03:52

Matthew Dominick, Mike Barratt,

play03:54

Jeanette Epps, and Tracy C. Dyson.

play03:56

And 3 astronauts from the Russian Space Agency Roscosmos,

play04:00

Oleg Kononenko, Nikolai Chub,

play04:02

and Alexander Grebenkin.

play04:04

Typically, there are 6-7 people on these expeditions,

play04:07

and this number, Expedition 71,

play04:09

indicates that this is the 71st team of crew members

play04:12

that have gone to the ISS on rotation.

play04:15

These expeditions have been going on for 24 years.

play04:18

In the year 2000, when the International

play04:20

Space Station was first launched.

play04:22

Since then,

play04:23

the ISS hasn't been left empty for extended periods of time.

play04:29

Someone or the other has lived in it.

play04:31

The Expedition 71 will end on 24th September 2024.

play04:34

And these astronauts present in the ISS,

play04:37

will return to Earth.

play04:38

And they will be replaced by the crew members of Expedition 72.

play04:42

And they can bring more food for these two astronauts.

play04:45

For now, NASA has said that Barry and Sunita,

play04:48

these two astronauts, are now parts of Expeditions 71 and 72,

play04:53

And they are now conducting research

play04:55

and experiments with the other astronauts.

play04:57

It's not like these two astronauts

play04:59

are stuck in space and are getting bored

play05:01

with nothing else to do.

play05:02

Expedition 71 is currently researching space botany.

play05:06

How flowers can be grown in space.

play05:08

On space-caused fluid shifts.

play05:09

On algae-based life support systems,

play05:12

as well as neuro-degenerative diseases

play05:14

and therapies are being researched at the ISS.

play05:18

Both Barry Wilmore and Sunita

play05:19

Williams are highly experienced astronauts.

play05:22

Barry is 61 years old

play05:23

he had already spent 178 days in space before this mission.

play05:28

Sunita Williams is an Indian-origin astronaut like Kalpana Chawla

play05:32

although she was born in America.

play05:34

She is 58 years old

play05:35

and before this mission, she has been in space for 322 days.

play05:39

Before this, she was a part of the Expeditions 14, 15, 32, and 33.

play05:43

She was also the commander of Expedition 33,

play05:46

so you can see how experienced she is.

play05:48

So, overall, these two astronauts should not have any problem,

play05:52

because they'll have food, water, and oxygen.

play05:54

Clothes were a little problematic

play05:56

because they were carrying clothes for only 8 days;

play05:58

they weren't carrying many things.

play06:00

But to solve this, NASA sent a shipment

play06:03

of their personal belongings on 6th August.

play06:05

So, this was about the astronauts.

play06:07

But now, let's talk about the problematic part.

play06:09

This Starliner spacecraft.

play06:12

Boeing's Starliner spacecraft

play06:14

is an orbital spacecraft.

play06:15

Its name is Cruise Space Transportation-100 Starliner.

play06:20

Also known as CST-100 Spaceliner.

play06:23

After SpaceX, Boeing is the only private company that

play06:26

has been able to launch an orbital spacecraft to the ISS.

play06:30

Now, what does an orbital spacecraft mean?

play06:32

Orbital spacecraft is a spacecraft

play06:34

that are launched at such high velocities

play06:35

that they can reach Earth's orbit

play06:37

and then orbit around the Earth.

play06:40

It requires a speed of more than 28,000 km per hour.

play06:44

On the other hand, suborbital spacecrafts

play06:46

reach the edge of space but

play06:48

they cannot reach high enough to orbit Earth.

play06:51

They reach the orbit for a while,

play06:52

experience a little weightlessness

play06:54

and then they come back down.

play06:56

The typical velocity of a suborbital spacecraft

play06:58

is less than 7,000 km per hour.

play07:01

Clearly, building an orbital spacecraft

play07:03

is much more difficult than building a sub-orbital spacecraft.

play07:06

Especially an orbital spacecraft

play07:08

that can facilitate humans travel.

play07:11

Apart from the private companies SpaceX and Boeing,

play07:13

only 3 countries which have been

play07:14

able to make a human orbital spacecraft.

play07:16

China, Russia, and the USA.

play07:19

And India is trying.

play07:20

Our Gaganyaan mission will aim at this.

play07:22

Sending humans to space in an orbital spacecraft.

play07:26

The first orbital test flight will be in December this year.

play07:30

Although, it will be an uncrewed flight.

play07:32

That is, there won't be humans in it.

play07:33

For the first test, they will seat a humanoid,

play07:36

named Vyomitra.

play07:38

Basically, they will test the spacecraft using this doll.

play07:41

Because if we start by sending humans

play07:43

and if a problem arises,

play07:44

it can be devastating.

play07:46

If we come back to NASA,

play07:47

they started their commercial crew program in 2011

play07:50

according to which they can collaborate with private companies.

play07:54

Many companies bid for this program

play07:56

including Blue Origin, Sierra Nevada and in 2014,

play08:00

SpaceX and Boeing were selected for this program.

play08:04

The first SpaceX Crew-1 flight was launched in November 2020,

play08:07

and it was a success.

play08:15

This was their spacecraft named Crew Dragon.

play08:19

It looks very similar to Boeing's Starliner spacecraft

play08:22

which looks like this.

play08:24

The crew module can seat 7 people.

play08:27

There is a window and a side hatch.

play08:29

You can see its interiors too.

play08:31

It shows a 5-person crew set-up.

play08:34

The noteworthy elements are its thrusters.

play08:36

These help the spacecraft fly,

play08:38

and move in different directions.

play08:41

These thrusters became the root of the problem

play08:44

due to which these astronauts are stuck in space right now.

play08:47

Similar uncertainties and difficult times can befall us at any time.

play08:51

Especially now that there are so many kinds of illnesses and diseases.

play08:55

To keep ourselves and our families

play08:57

secured in the face of such uncertainties,

play08:59

we need to have a health insurance.

play09:02

Especially now that the experts claim that

play09:05

health insurance is the need of the hour.

play09:07

In India, medical inflation has reached 14%.

play09:10

According to 2021 Finance Commission Report,

play09:12

70% of the expenditure on health,

play09:15

is borne out of pocket,

play09:16

because of which 60 million Indians,

play09:18

are pushed into poverty each year.

play09:21

Look at the National Insurance Academy's 2023 report,

play09:23

unveiled by IRDAI,

play09:25

it shows that

play09:26

73% of the Indian population isn't covered by health insurance.

play09:30

Since then, IRDAI has been working towards its vision,

play09:32

Insurance For All by 2047.

play09:35

Having health insurance doesn't prevent health problems.

play09:38

But it gives you peace of mind.

play09:40

And you get financial health when you need it the most.

play09:44

Star Health Insurance understands this need,

play09:46

they offer 24*7 support,

play09:48

and a network of more than 14,000 hospitals.

play09:51

Star Health is the first health insurance company in India,

play09:53

to achieve the milestone of settling more than 10 million claims

play09:57

since it was launched.

play09:59

They claim that 90% of the claims are settled within 2 hours.

play10:04

Plus, they offer Cashless Anywhere facility

play10:06

whether you need a routine checkup or an emergency medical treatment.

play10:10

For those interested, you can find the list in the description below.

play10:13

Use it to find the perfect health insurance plan for your family.

play10:17

Here, let's thank Star Health for sponsoring this video,

play10:19

and now, let's get back to the topic.

play10:21

The first launch date for Starliner CST was set to 6th May 2024.

play10:26

The launch of 5th June was actually planned for 6th May.

play10:29

But on 6th May, only 2 hours before the launch

play10:33

the countdown was stopped due to a faulty pressure valve.

play10:37

The Atlas V rocket

play10:38

to which this spacecraft is attached,

play10:39

had a faulty pressure valve.

play10:42

Then on 1st June,

play10:43

another attempt was made

play10:44

but it was cancelled again just 4 minutes before the launch.

play10:49

This time, instead of a human,

play10:50

a computer abort system was the one to cancel it.

play11:01

And then on 5th June,

play11:03

you'll find it hard to believe that before this scheduled launch,

play11:05

Boeing and NASA's engineers,

play11:08

were trying to manage a helium leak.

play11:10

Helium is the main gas which runs the propulsion system

play11:13

and fires the spacecraft's thrusters.

play11:16

When this spacecraft attaches to the International Space Station,

play11:19

and docks in it,

play11:20

bringing it to the exact line,

play11:22

docking, undocking,

play11:23

these are done by the thrusters.

play11:25

And to operate these thrusters,

play11:27

helium is needed.

play11:28

NASA and Boeing engineers said that

play11:30

there was a helium leak due to a defective seal.

play11:33

But this leak was not a big deal.

play11:35

It was manageable

play11:36

and wasn't supposed to cause a big problem.

play11:38

This is why the launch was postponed once again.

play11:47

But a few hours after the launch,

play11:49

two more leaks were discovered.

play11:51

When Starliner reaches the space station,

play11:53

they discover a fourth helium leak.

play11:55

After 4 leaks,

play11:57

the Commercial Crew Program Manager of Boeing finally admitted that

play12:00

they don't know what is the problem,

play12:03

and that they need to first understand the root cause.

play12:10

This is not an isolated error,

play12:11

this is a major systematic problem.

play12:13

Apart from this, another problem arose

play12:16

hours before the docking of the Starliner,

play12:18

it was found that 5 out of the 28 thrusters on the Starliner

play12:23

were not working properly.

play12:24

Seeing this happen, Spacecraft Commander Barry

play12:27

Wilmore had to manually control the spacecraft.

play12:29

Working with the engineers on the ground,

play12:31

he reset the thrusters

play12:33

and fired them again.

play12:34

4 out of 5 thrusters start working again.

play12:37

And so, the Starliner successfully docked at the ISS.

play12:42

Steve Stich, the Commercial Crew Program Manager at NASA says that

play12:45

this failure was due to a data issue.

play12:48

It had nothing to do with the hardware of the thruster.

play12:50

But because of all these problems,

play12:52

NASA had to face several questions.

play12:54

Could the astronauts rely on the

play12:56

Starliner spacecraft to return to Earth?

play12:59

Considering the numerous leaks

play13:01

and thrusters not working properly.

play13:04

After June 6, NASA and Boeing

play13:06

conducted some hot fire tests to check these thrusters.

play13:09

In these tests, they noticed that these thrusters

play13:11

were overheating and that is why they weren't working properly.

play13:14

They found that due to direct sunlight

play13:16

exposure on the capsule's manual control system

play13:18

there was substantial overheating.

play13:20

When these thrusters were tested again without sunlight,

play13:22

they were found to be operating normally.

play13:25

But overall, the engineers weren't sure

play13:27

whether the overheating problem would recur when the Starliner returns.

play13:32

This is why it was decided that

play13:34

the Starliner would return to Earth without the astronauts

play13:37

and for now, those astronauts would remain in the space station.

play13:41

Overall, this is good news that

play13:42

NASA prioritised safety

play13:44

otherwise everyone was reminded of the 2003 Challenger disaster

play13:48

when Kalpana Chawla

play13:49

was returning to Earth

play13:51

and her spacecraft exploded.

play13:56

I talked about it in detail in the video on Kalpana Chawla,

play13:59

about the exact mistakes back then.

play14:01

Here, NASA has decided to

play14:02

bring Sunita Williams and Barry Wilmore back to Earth

play14:05

using SpaceX's Crew Dragon spacecraft.

play14:08

In February 2025,

play14:10

when SpaceX's Crew-9 mission will go to the ISS,

play14:14

In that mission, instead of 4 astronauts, only 2 will be sent.

play14:17

So that these two astronauts can return with it.

play14:21

But because this can be possible only in February next year,

play14:23

so in total, these two astronauts will spend almost 9 months in space.

play14:28

NASA's Steve Stich

play14:29

calls Starliner a very capable spacecraft.

play14:33

He believes that it is not a bad spacecraft.

play14:35

But the two Starliner missions of before this,

play14:38

when it was tested without a crew, without humans,

play14:42

one of those tests had failed.

play14:44

The first Boeing Starliner mission

play14:46

was held on 20th December 2019

play14:47

known as the Orbital Flight Test.

play14:49

There weren't any humans in it,

play14:51

rather, it carried the doll Rosie the Rocketeer.

play14:53

Similar to the doll that would be carried

play14:55

by the Gaganyaan in a few months.

play14:56

The purpose of this mission was to remain in space for 8 days,

play15:00

dock at the International Space Station,

play15:01

and to return to Earth.

play15:03

But this mission was aborted just 2 days later.

play15:05

Starliner could not dock at the International Space Station.

play15:09

And why could it not?

play15:10

NASA and Boeing formed a joint review team to investigate this

play15:13

and this team gave about 80 recommendations to NASA and Boeing

play15:16

to solve this problem.

play15:18

Once again, the reason behind this

play15:19

was that Starliner's thrusters could not fire on time

play15:22

and so it could not reach the right orbit.

play15:25

The reason behind this was found to be

play15:26

the computer system's miscalibration of timing.

play15:29

Steve Stich had then said that

play15:31

NASA could not provide sufficient oversight to Boeing,

play15:34

because of which there were these software problems.

play15:37

The second test was conducted on 19th May, 2022.

play15:39

Boeing Orbital Flight Test 2

play15:41

and this time, it was successful.

play15:43

Rosie the Rocketeer actually reached the ISS.

play15:47

But even in that test,

play15:48

there were some glitches.

play15:49

Some thrusters weren't operating properly.

play15:52

The same problem as this year's launch.

play15:56

Interestingly, when NASA awarded the

play15:58

contracts to Boeing and SpaceX in 2014,

play16:01

the worth of SpaceX's contract was

play16:03

around $2.6 billion.

play16:04

And Boeing's contract was worth,

play16:06

$4.2 billion.

play16:08

But today, SpaceX has left Boeing so far behind that

play16:11

it is soon going to attempt one of the most riskiest missions.

play16:15

The world's first private spacewalk by an astronaut.

play16:18

A 20-minute spacewalk

play16:20

in which astronauts will take a walk outside the spacecraft.

play16:22

But Boeing's problems are not limited to space.

play16:25

Even as an airline company,

play16:27

Boeing has been subjected to criticism for the past few years.

play16:30

This is caused by Boeing's new 737 MAX commercial aeroplane

play16:33

and its deadly failures.

play16:36

On 5th January of this year,

play16:37

a Boeing 737 MAX of the Alaska Airlines

play16:41

took off for a normal flight from Portland, USA to Ontario.

play16:46

As soon as the plane reached an altitude of 16,000 feet,

play16:48

a door of the plane completely broke apart.

play16:52

This caused a huge hole

play16:53

and led to rapid decompression.

play16:55

People's phones, laptops, and

play16:57

everything that was light and not secured,

play16:59

flew out of the plane.

play17:01

Thankfully, since the passengers were wearing seat belts,

play17:04

no passenger fell out of the plane.

play17:07

They survived.

play17:08

But a few days later, during the Federal

play17:10

Aviation Administration's investigation,

play17:11

the cause was discovered to be loose hardware.

play17:14

The bolts in the door needed additional tightening.

play17:18

Alaska Airlines and United Airlines

play17:20

grounded all their 737 MAX aeroplanes.

play17:23

And in their investigations it was found that

play17:25

there were loose parts in many Boeing aeroplanes.

play17:28

Before this, in 2018,

play17:30

there was a faulty sensor in their plane,

play17:32

due to which Lion Air Flight 610

play17:35

crashed in Indonesia shortly after the take-off.

play17:38

All passengers and crew members of the flight were killed.

play17:40

After that, in 2019,

play17:42

a similar incident happened with the Ethiopian Airlines Flight 302.

play17:46

The plane crashed and all passengers were killed.

play17:49

It was revealed that the software installed by Boeing in the plane

play17:52

was a problematic software,

play17:53

in some cases, it took away the control from the pilots.

play17:57

The plane crashed due to the glitchy software

play17:59

and though the pilots tried their best to control the plane

play18:01

but they were unsuccessful.

play18:03

When this happened, all the Boeing 737 MAX planes

play18:07

were grounded for 20 months.

play18:09

Their safety enhancements were rechecked,

play18:12

and only after December 2020,

play18:14

did the plane re-enter into service.

play18:16

And now, in 2024, we are seeing more and more problems.

play18:20

Think about it.

play18:21

There have been many fake conspiracy

play18:22

theories regarding these plane crashes,

play18:24

but in reality, no one except the company can be blamed for those.

play18:28

The CEO of Boeing has stated that

play18:30

he will step down from his position,

play18:33

by the end of this year.

play18:34

This is an equally important but separate issue.

play18:37

The carelessness of Boeing and their failures.

play18:40

It has also been reported that

play18:41

the whistleblower who was about to testify against the company

play18:44

d!ed under sudden and mysterious circumstances.

play18:46

Anyhow, that can be a separate video,

play18:50

but for now, let's end this video here.
