What is the main reason Mars landing is described as "7 minutes of terror"?

• • It is a time of uncertainty due to the distance between Mars and Earth.

• • The spacecraft moves too fast to control manually.

• • There are numerous technical challenges during the descent.

• All of the above.

How does Adam Steltzner emphasize the difficulty of Mars landings in the first part of the video?

• • By using technical jargon to confuse the audience.

• • By highlighting the time delay and the spacecraft’s independence.

• • By stating that Mars has no atmosphere.

• • By focusing on the cost of the mission.

What is referred to as the "7 minutes of terror" in the video?

• The time taken to reach Mars

• • The critical entry, descent, and landing process on Mars

• • The duration for rover assembly

• • The communication delay between Earth and Mars

What does the term "perfect choreography" imply about the entry, descent, and landing (EDL) process?

• • The team manually adjusts every stage.

• • The process is carefully planned and must be executed flawlessly.

• • The spacecraft relies on Earth commands for guidance.

• • EDL is unpredictable and improvised.

How does the video explain the challenge of entering the Martian atmosphere?

• • The atmosphere is too thin to slow down naturally.

• • The atmosphere is thicker than expected.

• • The heat shield fails to protect the rover.

• • There is no atmosphere to assist in descent.

Why is Mars's atmosphere described as a "double-edged sword"?

• • It is too thick for spacecraft to pass through safely.

• • It is thick enough to cause drag but too thin to slow down the spacecraft completely.

• • It creates unpredictable weather conditions.

• • It allows for safe landing but damages instruments.
