A New Comet’s Very, Very Near Miss

The video discusses the historic approach of Comet Siding Spring to Mars, its discovery, and its origins from the Oort Cloud. It highlights the potential risks to Mars missions and the precautions taken to protect spacecraft. The video also emphasizes the scientific opportunities presented by the comet's close approach, allowing for the study of a pristine object from the early solar system. Finally, it mentions future comet exploration missions like Rosetta.

What is the significance of Comet C2013A1's close approach to Mars?

• It is the first comet to visit the inner solar system.

• It will be the closest look at a new comet.

• It will collide with Mars.

• It will pass by Earth.

What was the initial concern about Comet Siding Spring's trajectory?

• It would collide with Earth.

• It would miss the solar system entirely.

• It would make a direct impact with Mars.

• It would disintegrate before reaching Mars.

Why is the comet's coma considered a risk to spacecraft?

• It can damage spacecraft due to high-speed dust particles.

• It can cause spacecraft to lose communication.

• It emits strong radiation.

• It is made of toxic gases.

What measures are being taken to protect orbiters around Mars from the comet's coma?

• Sending them to Earth's orbit.

• Turning off their systems temporarily.

• Shielding them with special materials.

• Positioning them behind Mars.

Why is studying Comet Siding Spring important for understanding the solar system's history?

• It is the oldest comet ever discovered.

• It has a unique orbit that defies current models.

• It contains materials unchanged since the solar system's formation.

• It is the largest comet in the solar system.
