How will the movement of people and things change?
What a new and environmentally conscious future science!
_ Electric vehicles, autonomous driving, urban aviation, and space development

'Movement' has been a very important part of human life since ancient times, so we have been continuously researching 'Are there any better ways to help people and things move?'
To have the ‘ability to move (mobility)’ further, faster, more comfortably, and more safely.
This is how electric cars that don't emit exhaust fumes, autonomous vehicles driven by robots, urban aviation that soars through the sky to avoid traffic jams, and the development of rockets and space, which are new challenges for humanity, were born.

Recently, with the development of information and communication technology, transportation has become more innovative.
People started calling this movement mobility.
In the past, it was called transportation or movement, but it can be seen as a word with a slightly broader meaning.
Mobility is a combination of the words mobile (having mobility) and ability (able to do something), so it can be understood as 'a means of transportation that provides movement for people and things' or 'the ability to move'.
Generally, it refers to various services or means of transportation that enable the movement of people or objects.

Mobility incorporates all the latest scientific and technological advancements.
It requires an understanding of various fields such as machinery, electronics, chemistry, and information technology (IT), and in "10 Things You Need to Know About Mobility," all of this scientific knowledge is explained in a very fun and easy way with illustrations.
So, as we read about the past, present, and future of movement, we encounter fascinating science and our anticipation grows.
Let's delve into the allure of mobility, a collection of diverse technologies and an environmentally conscious science.

Instead of using fuels like gasoline or diesel that can be easily purchased at gas stations, you might wonder, 'Why do we suddenly want to use electric energy?'
(…) Think about why gasoline-powered cars that travel on the road couldn't be driven inside the house.
If you were driving a fuel-burning car inside a house surrounded by walls and windows on all sides, the gases it produces (exhaust gases) would fill the space.
It's a situation that can be easily predicted without actually trying it.
The reason is that cars that burn fuel, that is, cars with internal combustion engines, emit carbon dioxide.
And it will emit various toxic gases that are bad for our health and the environment (like nitrogen oxides, which came to light during Dieselgate).
This is the biggest difference between an engine-powered car and an electric car, which emits no emissions when moving.
It's the same reason why the cars we drive in our daily lives are becoming increasingly electric.
Internal combustion engine vehicles, which have been conveniently used for a long time, inevitably emit carbon dioxide because they burn fuel.
But carbon dioxide is one of the greenhouse gases that causes climate change.
To avoid emitting greenhouse gases while still serving as a means of transportation, it has become necessary to replace vehicles with electric ones.

Fifteen unique cars, each equipped with various driving devices, started off one by one at the starting line set up at the Slash X ranch.
The vehicles came in all shapes and sizes, from six-wheeled cars, trucks, military trucks, and even motorcycles.
Each team did their best to apply their own ingenious ideas to create a self-driving car that could control its own direction and speed.
Every team had only one goal.
The goal was to reach the destination, 142 miles (about 229 kilometers) away, on a rugged, sandy desert road in less than 10 hours.
The team compositions were also diverse, including college teams, corporate teams sponsored by specific companies, and even a student team from a California high school! Unfortunately, two of the 15 driverless cars withdrew before even starting, and three veered off course near the starting line or crashed into a nearby wall, failing to finish the race.
In the end, none of the cars that participated in this competition reached the destination within the allotted time.

Helicopters, as we know, use engines.
That's why they emit carbon dioxide when they move.
Helicopters are expensive, but they are also difficult to use actively in urban areas where pollution is already a problem due to the abundance of cars on the roads.
These problems can be solved by using electric airplanes.
The original official name is 'electric Vertical Takeoff and Landing vehicle', but it is abbreviated as e-VTOL.
But let's call it an electric airplane, in simple terms.
Electric airplanes use batteries and motors, so they don't emit carbon dioxide when they fly.
If it's made to take off and land vertically like a helicopter, there's no need for a long runway, and since you can use the existing helipad, there's no need to build new facilities, which is better.

But in the 21st century, a different situation arose.
A space launch vehicle development company called SpaceX, founded by Elon Musk, has emerged.
Previously, public institutions such as NASA (National Aeronautics and Space Administration), which were funded by taxpayer money, took the lead in developing space launch vehicles.
SpaceX is the first private company to successfully build a space rocket using capital rather than taxpayer money.
Space rockets were considered an impossible field because they cost too much to develop and were too costly for private companies to undertake directly.
But SpaceX is the first to break this.
We successfully launched a satellite into orbit using a space rocket called Falcon 1.
But this isn't all that SpaceX has achieved.
You may have seen it on YouTube or TV news.
I'm talking about a rocket that looks like a cylinder, soars into the sky, and then returns to where it was launched.
That's right, SpaceX has built the world's first reusable space rocket.
