What does a welder do? A welder uses tools that join two or more parts through forces such as heat or pressure. Metals are the materials most commonly used in welding, but it’s also possible to weld thermoplastics or wood. Welders use their hands, skills, and problem-solving abilities to create something new. At NASA, welders […]

What is AI? (Grades 5-8)
This article is for students grades 5-8. What is AI? Artificial intelligence, or AI, is a type of technology that helps machines and computers have “thinking” abilities similar to humans. Devices using AI can learn words and concepts, recognize objects, see patterns, or make predictions. They can also be taught how to work autonomously. AI […]
What Are Asteroids? (Ages 14-18)
What are asteroids? Asteroids are rocky objects that orbit the Sun just like planets do. In fact, sometimes asteroids are called “minor planets.” These space rocks were left behind after our solar system formed about 4.6 billion years ago. Asteroids are found in a wide range of sizes. For example, one small asteroid, 2015 TC25, […]
