AOW Week 30

Read this conclusion.

Perseverance's mission to Mars will help scientists to better understand the planet's history.

Which sentence from the article provides the BEST support to the statement?

• The rover traveled 470 million kilometers (300 million miles) journey over seven months.

• It will search for evidence of microbial life that could have existed on Mars billions of years ago.

• The mission will also test new technology that will help to lay the groundwork for future missions to Mars.

• The hope is that the Perseverance mission, along with others, will help to achieve this goal.

Which detail from the article shows how NASA tried to solve the problem Ingenuity might face on Mars?

• It moves on its own by using two computers to navigate. One computer figures out where the rover needs to go and the other computer "sees" its surroundings.

• Density measures how tightly packed particles are. Because of this difference, flying on Mars could be difficult. The helicopter might have a harder time achieving lift.

• This is a mechanical force that holds an aircraft in the air by directly opposing its weight. Lift is the push that lets an object move up.

• For one thing, the helicopter is extremely light. And to generate lift, its blades are much larger and spin many times faster than a helicopter on Earth would.

What is the MOST likely reason the author included the information about Viking 1 and 2?

• to highlight the first rovers to explore Mars back in 1976

• to highlight the earliest missions to Mars that arrived successfully

• to bring attention to the idea that many missions to Mars have failed

• to bring attention to the idea that NASA plans to send humans to Mars

Read the following selection introducing Ingenuity.

Also on board the rover is a tiny helicopter called Ingenuity. It weighs only 1.8 kilograms (4 pounds) and is solar-powered. The helicopter will be the first powered aircraft to attempt a flight on another planet.

What does the author MOST LIKELY want the reader to think about Ingenuity based on this selection?

• It is a small and light aircraft that will make history when it flies on Mars.

• It is a new and swift aircraft that relies on Perseverance for power.

• It is a little aircraft that will have difficulty flying on another planet.

• It is a quick aircraft that weighs more than a typical solar-powered helicopter.
