Questions & Answers

Q: What is the purpose of the NEO Surveyor mission?

The NEO Surveyor mission aims to locate potentially dangerous asteroids that could pose a threat to Earth. It will use a special infrared telescope to spot asteroids even if they are dark and emit infrared radiation.

Q: How do scientists observe IO's volcanic activity from Earth?

A telescope called IO IO helps scientists observe IO's volcanic activity by blocking the light from Jupiter. This enables them to detect the faint effects of IO's eruptions and study its volcanic behavior.

Q: How is water created on the Moon by the solar wind?

When hydrogen atoms in the solar wind collide with the Moon's surface, they break apart other molecules and combine with oxygen, forming water. This process has been confirmed by China's Chang'e 5 mission, which returned lunar samples containing water.

Q: How will space power be tested?

A space mission will harvest solar energy using solar panels and transmit it back to Earth through microwaves. This test aims to determine the efficiency and feasibility of using space-based solar power as an alternative energy source.

Summary & Key Takeaways

• NASA is preparing the NEO Surveyor mission to locate dangerous asteroids flying close to Earth.

• IO, a moon of Jupiter, had a volcanic eruption visible from Earth, revealing the moon's volcanic activity.

• The solar wind may be responsible for the creation of water on the Moon's surface.

• A test of space power involves harvesting solar energy in space and transmitting it to Earth.
