Speed Records in Space?

Speed Records in Space
Taking advantage of Jupiter's gravity, New Horizons reached a speed of 84 thousand km per hour and set out towards Pluto. In 2015, he went out of the solar system after sending the pictures he took from Pluto to the world.

The largest rocket ever sent into space is 121 meters high! This 150-ton rocket is a very large rocket.

Of course, this was an experiment, and after dozens of unsuccessful interim attempts and the last attempt to send fully prepared space travel into space, which ended in failure, it is said that this second one has finally resulted in success.

Those who are curious about the details of this launch or want to see the moment of launch should look it up on the internet. SpaceX live broadcast recording is probably available on YouTube.

In this article, I want to talk about something related to the subject, but a little different.

In the live broadcast, after Starship successfully separated from the fuel tank, it continued to an altitude of 148 km from the ground, and when it reached a horizontal position, that is, when it entered the orbit around the earth after going into space, its engines were stopped when it had a speed of slightly more than 24 thousand km per hour.

During the live broadcast, they said that the connection was lost at the 8th minute, but they said that it would return to the world the next day, so it probably did somehow.

They were talking about how they would make smoother launches next time with the information obtained from this test.

For someone with so much money, the cost of this launch is probably prohibitive.

Yes, 24 thousand km per hour! Isn't that amazing speed?

Currently, there are already satellites in orbit higher than the ground and moving faster around the earth.

So, although this speed seems quite high, it is actually not that high.

I wonder what the speed limit we can reach in spacecraft with today's technology?

How much is the record?

I took a look at the internet and saw that much higher speeds could be achieved with the spacecraft produced by humanity.

For example, Voyager 1, which is currently continuing its journey in deep space outside the solar system, is traveling at a speed of 62 thousand km per hour.

Helios satellites also reached speeds of up to 250 thousand km per hour by taking advantage of the gravitational pull of the sun.

The speed record is written on the internet as being held by the Parker Solar Probe probe sent to the sun.

Speed of 700 thousand km per hour!

They probably reached this speed during their journey to the sun, maybe they haven't yet.

It is said that the probe is currently rotating at a speed of 246 thousand 960 km / h in its orbit around the sun, but it is written that its orbit will shrink by getting closer to the sun every day and will reach a speed of up to 690 thousand km / h in 2025.

In other words, some information written on the internet may be wrong. He may not have broken the speed record mentioned at the end yet. This speed record may also be the planned maximum speed.

Another spacecraft that has now left the solar system is New Horizons.

Taking advantage of Jupiter's gravity, it reached a speed of 84 thousand km per hour and set off towards Pluto. In 2015, he went out of the solar system after sending the pictures he took from Pluto to the world. Currently, its mission outside the solar system, like the Voyager satellites, is continuing.

Of course, these record speeds are the speeds of unmanned space vehicles.

The record speed among manned spacecraft belongs to Apollo 10. Speed of 39 thousand 896 km per hour!

The circumference of the Earth at the equator is 40 thousand km. At this speed, an astronaut in Apollo 10 could circle the world in an hour.

Now I remember the story of going around the world in 80 days.

With the current technology, human beings can go 1920 times faster than the speed in the novel.

In fact, there has only been a human being in history who has been able to go this fast.

The speed required to escape the Earth's gravity is 42 thousand kilometers per hour.

The launch speed required to go out of the solar system was 151 thousand kilometers per hour.

Of course, these speeds are the speeds required to escape the gravity of the earth or the sun with a direct constant speed, without any engine thrust behind it.

The speed at which rocket engines can propel the spacecraft while leaving the atmosphere is around a few thousand kilometers per hour. After atmospheric friction ends, it is possible to easily increase speed.

That's why it can be easily taken off from the lunar surface. The gravity of the moon is 6 times lower than that of the earth, and since there is no atmosphere on the moon, there is no such problem as air friction.

I wonder what will be the record speed for manned flights?

As technology progresses, more powerful engines are made and new technology space vehicles can go much faster.

Even though you're going at this speed, if you don't have any acceleration, you shouldn't feel anything.

I wonder what it feels like though?

Do you think anything will change just because you're going fast?

If you ask Einstein, you don't feel anything.

But if you go fast enough, you will definitely find those you left behind much older when you return.

You may not be able to find any at all.

Let me end the article here by saying I wish you a fast and good life.
