NASA | Top Solar Discoveries: #1

Space weather, driven by the sun's energetic output, affects global communication and power systems. The solar wind, composed of protons and electrons, interacts with Earth's magnetic field. Satellites study solar phenomena like flares and coronal mass ejections, which can disrupt power grids and harm astronauts. Missions aim to enhance our understanding and prediction of space weather.

What is the primary source of space weather?

• The sun's energetic output

• The moon's gravitational pull

• The Earth's atmosphere

• The Earth's core

What particles make up the solar wind?

• Neutrons and photons

• Protons and electrons

• Protons and neutrons

• Neutrons and electrons

At what speed can solar wind particles travel?

• Up to 500,000 miles an hour

• Up to 2,000,000 miles an hour

• Up to 1,000,000 miles an hour

• Up to 1,500,000 miles an hour

Which of the following is NOT an effect of space weather?

• Radiation risks for astronauts

• Increased rainfall on Earth

• Power outages in high latitude grids

• Disruption of spacecraft

Why are space weather prediction missions important?

• To understand the sun's impact on Earth

• To improve weather forecasts on Earth

• To explore other planets

• To study the Earth's core
