NASA International Space Apps Challenge
NASA has a big event called the Space Apps Challenge. It is very big and happens every year. People who join this event work together for two days. They use special information from NASA to solve problems on Earth and in space. Many people meet up or talk online to think of new ideas.
At first, the event was about space, but now it includes Earth too. They also have art challenges. It is for many kinds of people to enjoy.
NASA's big bosses started this event and now other important people at NASA are in charge. A big leader named President Obama wanted to help people work together. The event is part of this big idea.
The Space Apps Challenge helps people learn about Earth and space. It also helps people to create new things and become leaders. Over 220,000 people have joined the event.
NASA wants people to help solve problems and make new things. They invite everyone to join and have fun learning and creating!
Some companies make things that fly in the sky, like planes and rockets. They build them, test them, and fix them. Flying things can be for travel or for the army. There are special rules for making these things.
Flying things can cost a lot of money. In 2015, people spent a lot of money on big planes, small planes, army planes, and helicopters. More money was spent on fixing them. In 2017, the whole world spent lots of money on things that fly and things for space.
The United States makes the most flying things. France, China, and other countries also make many flying things. These countries are very good at making them.
People keep studying about how to make better things that fly. They sometimes give awards to the best companies for making flying things.
Aerospace engineering is about making planes and spaceships. It has two main parts: making planes (aeronautical) and making things for space (astronautical). There is also avionics engineering, which is about the electronic parts of planes and spaceships.
A long time ago, people only made planes, so it was called aeronautical engineering. Later, when people started making things for space, they started calling it aerospace engineering.
Planes and spaceships go through tough conditions, like changes in the air and temperature. They are made with the help of many kinds of science and engineering, like the study of air, engines, electronics, materials, and how to build strong structures.
People work together in teams to make planes and spaceships because it needs lots of different skills.
A long time ago, a man named Sir George Cayley helped start aerospace engineering. He was very important in history because he learned a lot about how planes fly.
People first learned about engineering for planes by trying things and learning from other types of engineering. Some smart people in the 18th century knew some things about it. In 1903, two brothers named the Wright Brothers showed the world how to make a machine that flies with a person inside.
