Voyager 1 and Interstellar Exploration

What does it mean for Voyager 1 to be "one light-day away" from Earth?

• It is one day closer to reaching another star.

• It is traveling at the speed of light for one day.

• Light from Earth takes one full day to reach Voyager 1.

• It has been traveling for exactly one day.

When was Voyager 1 launched and what was its first main mission?

• 1977, to study Mars and Jupiter.

• 1977, to study Jupiter and Saturn.

• 1989, to study Uranus and Neptune.

• 2012, to enter interstellar space.

What significant boundary did Voyager 1 cross in 2012 to enter interstellar space?

• The Kuiper Belt.

• The Oort Cloud.

• The heliopause.

• The asteroid belt.

Why is communicating with Voyager 1 so difficult?

• Its signals are too strong and interfere with other satellites.

• Its signals are extremely weak and take a long time to travel.

• It is constantly changing its position, making it hard to track.

• There are too many other spacecraft sending signals at the same time.

What is expected to happen to Voyager 1's communication by the early 2030s?

• It will start sending stronger signals.

• It will switch to a new power source.

• Contact will end because it won't have enough power for its transmitter.

• It will return to Earth for repairs.

Why is it hard for humans to control the Voyager 1 mission in real-time?

• The signals travel too fast.

• The spacecraft is too small to see.

• The distance causes long delays in communication.

• There are too many asteroids in the way.

Where is Voyager 1 headed after leaving the main part of the solar system?

• Towards the Sun

• Towards the Oort Cloud

• Towards Jupiter

• Towards another galaxy

What marks the true boundary of our solar system?

• The edge of the Kuiper Belt.

• Where the Sun's gravitational pull becomes very weak.

• The orbit of Pluto.

• Where the stars begin.

What special item does Voyager 1 carry to send a message to possible alien life?

• A telescope

• A Golden Record

• A powerful laser

• A flag from Earth

What is the main lesson we learn from Voyager 1's long journey?

• Spacecraft need to be very fast to explore far away.

• It's impossible to explore deep space.

• With patience and time, even slow journeys can go very far.

• Only new technology can help us explore space.
