Seven Minutes of Terror

The video includes a print graphic that states: Mars’ atmosphere is 100 times thinner than Earth’s. This fact helps the viewer to understand that —

• the atmosphere is not thick enough to slow down the space vehicle

• the space vehicle will be able to easily penetrate the atmosphere

• the atmosphere could cause the space vehicle to explode upon entry

• the space vehicle is not affected by atmospheric conditions

Which details from the video explain why the spacecraft’s parachute is unusual? Mark the correct box for each sentence.

• It expands by filling up with gases in the atmosphere.

• It is attached to the spacecraft with multiple tethers.

• It slows the spacecraft down to about 200 miles per hour.

• It weighs 100 pounds but can withstand 65,000 pounds of force.

• It is the largest and strongest supersonic parachute ever built.

Which two statements from the video best support the answer to Part A?

• So, when we first get word that we’ve touched the top of the atmosphere, the vehicle has been alive—or dead—on the surface for at least seven minutes. (00:45–01:00)

• Because we’ve got literally seven minutes to get from the top of the atmosphere to the surface of Mars . . . (01:12–01:18)

• We slam into the atmosphere and develop so much aerodynamic drag, our heat shield, it heats up and it glows like the surface of the sun. (01:36–01:44)

• During entry, the vehicle is not only slowing down, violently, through the atmosphere, but also we are guiding it, like an airplane, to be able to land in a very narrow, constrained space. (01:48–02:00)

• The radar has to take just the right altitude and velocity measurements at just the right time, or the rest of the landing sequence won’t work. (02:54–03:01)
