Apollo Missions to the Moon

Read the excerpt from Team Moon.

The heavier the spacecraft, the harder it is to launch. And fuel is heavy. So it was critical to pinpoint the fuel needed, add a cushion, then take no more than necessary. But now, because the landing was taking far longer than planned, the fuel was almost gone. Mission Control wanted Neil to take as much time as he needed and fly the LM as near empty as possible onlybecause they wanted him to make the landing. But if he ran out of fuel above the surface, in all likelihood the LM would crash onto the moon. So they were trying to time it to the last possible second before calling an abort—calling off the landing.

Which detail from the excerpt identifies a solution?

• they were trying to time it to the last possible second

• the fuel was almost gone

• And fuel is heavy

Why does the author use a problem-solution text structure in the paragraph?

• to help the reader understand how the fuel system on a spacecraft works

• to help the reader understand the difficult decisions faced by Mission Control

• to help the reader understand how the country’s space program got started

The trouble with option 2 was that the venting might push the fuel to an unstable condition. Or, another possible outcome of the “burping”: what if the landing gear hadn’t deployed correctly? Could any movement, or any resulting burst—no matter how small—tip the LM over? Many a voice in the debate thought the safest option was to abort—now! But that opinion was quickly overruled by the Grumman and NASA leadership (who were confident of the landing gear), and the consensus of the leaders was that it would be safe to gently, gently burp the engine.

Read the excerpt from Team Moon.

So they came by the thousands—kids, really, twenty-somethings, a few in their thirties. No one knew for sure how to get to the moon, how to land, or get home. But their goal was clear-cut, and that was enough. That gave them purpose: a reason to puzzle out the problems and seek solutions rather than sleep.

Absolutely no one expected it to happen. They painstakingly planned so it absolutely wouldn’t-couldn’t happen. But here they were, less than five hundred feet from the moon, and just about plumb out of fuel.

Which detail from the excerpt best identifies the problem?

• just about plumb out of fuel

• they painstakingly planned

• no one expected it to happen

Which best states how information in Team Moon and the NASA article are the same?

• Both give detailed information about problems faced during the moon landing.

• Both give information about the entire Apollo 11 flight from launch to landing.

• Both give information about the moon landing of the Apollo 11 space mission.

Which best states how information presented in Team Moon and the NASA article are different?

• The NASA article covers the entire Apollo 11 flight, while the Team Moon article is mostly about the landing.

• The NASA article is about the Apollo 11 mission, while the Team Moon article is mostly about the “space race.”

• The Team Moon article is about President Kennedy, while the NASA article is about Neil Armstrong.

Which detail is included in both Team Moon and the NASA article?

• The lunar module was only a few seconds away from having no fuel when it landed.

• The Apollo 11 spacecraft required 7.5 million pounds of thrust to be propelled into space.

• The Apollo 11 spacecraft entered lunar orbit three days after it was launched from earth.
