Apollo 11 Mission Quiz 1

What crucial steps did the Apollo 11 crew take during the launch phase to safely orbit the earth?

• Activated onboard computers and monitored systems

• Performed trans-lunar injection burn to escape earth's orbit

• Conducted testing of lunar module systems

• Carried out separation procedure for command module and lunar module

Answer explanation

Explanation: The video shows the Saturn V rocket performing the crucial trans-lunar injection burn, firing the engines to propel Apollo 11 out of earth's orbit towards the moon.

How did the Saturn V rocket provide the massive power required to propel Apollo 11 out of earth's orbit towards the moon?

• Multiple synchronized engines providing over 1 million pounds of thrust

• Lightweight composite materials reducing weight

• Computerized navigation and trajectory tracking

• Use of solid rocket boosters

Answer explanation

Explanation: The video emphasizes the Saturn V's huge clustered first stage engines and their combined thrust of over 7 million pounds.

What challenges did the crew face when attempting to dock the lunar module with the command module in lunar orbit?

• Precisely matching the modules' orbits and speeds

• Navigating to the far side of the moon

• Coordinating the docking maneuver

• Handling communication delays

Answer explanation

Explanation: The video highlights the delicate orbital dynamics required to rendezvous and dock the lunar module with the command module in lunar orbit.

How was the lunar module Eagle designed and engineered to support landing and takeoff from the lunar surface?

• Powerful ascent engine and lightweight construction

• Navigation computers and software

Answer explanation

Explanation: The video shows the Eagle had a lightweight aluminum body and limited ascent engine to allow landing and lift off from the moon.

What precise maneuvers did Armstrong have to carefully execute to land the Eagle on the moon's Sea of Tranquility?

• Pitch adjustments to descend vertically

• Activating module's landing radar

• Igniting retrorockets on final approach

• Laterally translating spacecraft

Answer explanation

Explanation: Video footage shows Armstrong pitching the Eagle up to descend vertically to the landing site using the engine thrust.
