Meteorites are (usually) gifts from the heavens. They provide unique insights to parts of the solar system that we couldn’t access otherwise - either because it's too expensive, or because the solar system itself has evolved since it was formed. A new paper from researchers at the University of Colorado Boulder details how one particularly famous meteorite offers a window into just such a bygone age of the solar system - and the failed planet that was a part of it.

4 Min Read NASA Knows: What Is Mass Distribution?

This article is for students grades 5-8.

Mass distribution affects everything from galaxy shapes to aircraft design to planetary rotation. It’s used to map stars in our universe, figure out what planets are made of, and even to determine how luggage is loaded onto an airplane.

Mass distribution can be a tricky thing to understand. So, let’s explore it using an everyday example: a soccer ball.

How Does Mass Distribution Affect Center of Mass?

Have you ever kicked a soccer ball and wondered why it curves, spins, or sometimes wobbles? Mass distribution plays a part.

On the outside, soccer balls look simple – a series of geometric shapes woven together in a pattern. But on the inside, they are carefully engineered. The key to a great soccer ball is something you can’t see: how the mass is distributed inside the ball.

When engineers build a soccer ball, they try to make sure its mass is evenly balanced in all areas. This is because the way a ball spins and flies depends on how its mass is arranged. If one part of the ball is slightly heavier, its center of mass shifts. If the ball’s center of mass isn’t precisely balanced, the ball won’t move smoothly.

Words to Know

mass: the measurement of the amount of matter in an object

mass distribution: how mass is spread within an object

center of mass: the unique point around which the mass of an object is perfectly balanced

How Is Mass Distribution Measured?

Scientists and engineers use tools like precision scales, computer models, and repeated testing to determine an object’s mass distribution. These efforts help them design balanced airplanes, rockets, and even soccer balls. Their goal is to achieve dynamic balance, meaning the object can travel smoothly without unexpected movements.

How Does Gravity Affect How We Study Mass Distribution?

On Earth, gravity hides some of the details about how objects move. In microgravity, astronauts can observe motion more clearly. In 2019, Adidas partnered with NASA and sent soccer balls to the International Space Station.

Astronauts conducted tests to help engineers confirm their designs and understand the physics behind ball motion in ways they simply can’t on Earth. The results of the space station experiments have already helped improve the accuracy and consistency of modern soccer balls.

Try It Yourself

You don’t need to go to space to explore the physics of a ball in motion. Try this experiment at home or school:

• Grab different types of sports balls (soccer ball, basketball, tennis ball)
• Spin each one on the ground or between your hands
• Watch for wobbling, flipping, or smooth spinning

Can you tell which balls are well balanced? Or which ones might have uneven mass distribution?

Career Corner

Are you interested in a career that explores the science and engineering of mass distribution? Many different occupations can help you strike the perfect balance. Here are a few examples:

Computer-Aided Design (CAD) Technician/Drafter: These specialists convert sketches and engineering designs into technical drawings. They use powerful computer software to create detailed 3D and 2D drawings of objects. A two-year associate degree from a technical or community college is key to this career path.

Computational fluid dynamics engineer: These engineers use computer simulation tools to model and analyze fluid behavior in real-world situations. They might study airflow around sport ball designs or explore ways to improve aircraft wings. They need a strong background in engineering and the ability to analyze complex problems.

Physicist: These scientists study matter and energy. They develop models and theories to explain how things work, conduct experiments, and use math to better understand the universe. A career in physics demands a strong understanding of math and complex problem-solving and usually requires an advanced college degree.

Neptune is definitely the odd one out of the gas giants. It’s tilted at a strange angle, and its moons are completely different from any other gas giant we know of. A new paper, published in Science Advances from researchers at CalTech, posits that might be because Triton, by far Neptune’s largest moon, absolutely obliterated the regular moon system it previously had, except for one particular exception - Nereid.

For decades, economic growth and fossil-fuel consumption have been tightly intertwined. As cities have expanded, rising prosperity has often been accompanied by worsening air pollution. New research, however, suggests that this relationship is changing – and satellite data are helping to prove it.
