It allowed the warhead to function as a recoverable payload capsule with a parachute

It increased the rocket’s speed by reducing drag

It allowed the rocket to carry nuclear weapons safely

What was the significance of adding a detachable warhead to the R2 rocket?

This test evaluates knowledge about Sergey Korolev's contributions to rocket technology and early space missions.

The chief designer of Soviet rocket development and space missions

An American scientist who developed the V2 rocket

Who was Sergey Korolev in the context of space exploration?

It was the first rocket to launch an artificial satellite into orbit

It was the first rocket developed in the United States

It was the first rocket to land on the Moon

What notable achievement is attributed to Korolev’s R7 rocket?

To keep his identity and work a secret during the Soviet era

Because he worked anonymously in the United States

Because he was not important to the Soviet space program

Why was Sergey Korolev referred to only as the 'chief designer' during much of his career?

Extended the fuel tanks and improved propulsion, doubling the range

Converted it to use solid fuel instead of liquid fuel

Reduced the size to make it portable by infantry

Added a nuclear engine for longer space flights

What was one key improvement Korolev's team made to the German V2 rocket design?

Launching the first human, Yuri Gagarin, into space

Conducting the first spacewalk outside the spacecraft

What milestone did the adapted R7 rocket (Vostok) achieve in 1961?

Because the launch crew had taken to drinking the ethyl alcohol fuel

Because methyl alcohol was cheaper to produce

Because ethyl alcohol was too volatile for launches

Because methyl alcohol provided more thrust

Why did the Soviets replace ethyl alcohol fuel with methyl alcohol in their rocket designs?

Their range was too short and the warhead too small

They were banned by international treaties

They were launched only as scientific probes

What is one reason the R1 and R2 rockets did not become widely used as military weapons?

All subsequent Soviet and Russian launch vehicles are based on its design

It was retired and has no impact on modern rockets

It inspired American space shuttles design directly

It was replaced by solid-fuel rockets in the 1960s

What is the legacy of the R7 rocket design in modern space exploration?

It demonstrated the ability to send and safely recover living creatures from high altitudes

It was the first animal launched into orbit around Earth

It marked the first intercontinental ballistic missile test

It led directly to the first human spaceflight without further testing

What was significant about Korolev’s launch of two dogs in 1951 using an R2 rocket?
