The Space Race

On 4 October 1957, a shiny metal ball about 58 cm wide began to circle Earth. It sent out a simple radio beep. That beep frightened a superpower. Twelve years later, two Americans walked on the Moon.

In this lesson, we follow the Space Race step by step. We see Sputnik, Gagarin, Kennedy’s Moon goal and Apollo 11. We also see why the Soviet Union lost the Moon contest, and how the rivals later shook hands in orbit.

1Why did Sputnik start a race?

The Space Race was a Cold War contest. The rivals were the United States and the Soviet Union. Each wanted science results and world prestige. Each also wanted strong rockets for defence.

On 4 October 1957, the Soviet Union launched Sputnik 1. It was the first artificial satellite. Its radio signal was easy to pick up on Earth. It sent signals for about three weeks. Then its batteries ran out.

Many Americans felt shocked. A rocket that could lift a satellite could also carry a weapon far away. Fear spread fast. Leaders felt pressure to act.

• 4 October 1957: Sputnik 1, the first artificial satellite.
• The beep caused a public scare in America.
• Rockets served both science and defence.

2How did America answer, and what is NASA?

The US launched its own satellite, Explorer 1, on 31 January 1958. It helped find the radiation belts around Earth.

Congress then created NASA in 1958. NASA means the National Aeronautics and Space Administration. It grew out of an older research body called NACA. It gave the country one civilian agency for space work.

NASA did not start with a Moon landing. It built skills in steps. Project Mercury tested human flight. Project Gemini practised longer flights, spacewalks and docking. Apollo came last.

• Explorer 1: 31 January 1958.
• NASA was created in 1958, from NACA.
• Steps: Mercury, then Gemini, then Apollo.

3Who was first in space?

The Soviet Union took the next big lead. On 12 April 1961, Yuri Gagarin flew aboard Vostok 1. He made one full orbit of Earth. The flight lasted about 108 minutes. He was the first human in space.

The American reply came weeks later. On 5 May 1961, Alan Shepard flew on a short flight. His craft reached space but did not orbit. He was the first American in space.

In June 1963, Valentina Tereshkova became the first woman in space. The Soviet Union led many early firsts.

• 12 April 1961: Gagarin, first human in orbit.
• Shepard was the first American in space. He did not orbit.
• Tereshkova: first woman in space, 1963.

4Why did Kennedy set a Moon goal?

Gagarin’s flight raised the pressure on America. President John F. Kennedy answered on 25 May 1961. He asked the nation to land a person on the Moon before the decade ended. He also asked to bring that person home safely.

The goal was huge. It needed a giant rocket and careful navigation. It also needed a safe way back to Earth. Congress paid large sums. NASA and its partners built each part.

The path was risky. In January 1967, a cabin fire killed three Apollo 1 astronauts during a ground test. They were Gus Grissom, Ed White and Roger Chaffee. NASA changed the craft and its safety rules.

• 25 May 1961: Kennedy’s Moon goal, weeks after Gagarin.
• Target: land and return before 1970.
• 27 January 1967: the Apollo 1 fire killed three astronauts.

5How did Apollo 11 reach the Moon?

Apollo 11 had three crew members. Neil Armstrong was the commander. Buzz Aldrin flew the lunar module, called Eagle. Michael Collins flew the command module, called Columbia.

A Saturn V rocket lifted them from Earth. After a three-day trip, Eagle left Columbia and landed on 20 July 1969. Collins stayed in orbit around the Moon.

Armstrong stepped onto the surface first. Aldrin followed soon after. They gathered rocks and set up tools. Then Eagle lifted off and met Columbia again. The crew returned to Earth on 24 July. Kennedy’s goal was met.

• 20 July 1969: Eagle lands. Armstrong steps out first.
• Collins stayed in orbit in Columbia.
• The crew was back on 24 July.

6Why did the Soviet Union lose the Moon race?

The Soviet Union did not simply lose everywhere. Its robot probes did great work. On 3 February 1966, Luna 9 made the first soft landing on the Moon. That was before any human went there.

But the Soviet crewed Moon plan needed a giant rocket called the N1. All four N1 launch attempts, between 1969 and 1972, failed. No cosmonaut ever landed on the Moon.

Space was dangerous for both sides. In April 1967, cosmonaut Vladimir Komarov died when the parachute of Soyuz 1 failed. Rival design plans and lost time also hurt the programme.

• Luna 9: first soft landing on the Moon, February 1966.
• The giant N1 rocket failed on all four launches.
• Komarov died in Soyuz 1, April 1967.

7What did the race leave behind?

The race built new skills in rockets, spacecraft and science. Moon missions brought back rocks to study. Satellites later helped with weather, radio and mapping. Not every modern gadget came from the Space Race, though. Many fields had other sources of progress.

The costs were high. Defence goals also shaped much of the work.

The rivalry did not stay the same forever. In July 1975, an American Apollo craft docked with a Soviet Soyuz craft. The two crews met in orbit and shook hands. The mission did not end the Cold War. But it showed that rivals could work together.

• Skills in rockets, satellites and Moon science.
• 17 July 1975: Apollo-Soyuz docking in orbit.
• A sign of cooperation, not the end of the Cold War.

8What are the exam traps?

• Match each first to its goal. Sputnik: satellite. Gagarin: human orbit. Apollo 11: human Moon landing.
• First Moon landing can mean a robot or a human. Luna 9 was a robot. Apollo 11 carried humans.
• Shepard was first American in space. Gagarin was first human in orbit.
• Do not call it a single-country win. The Soviets led early. The US landed first.
• Sequence: 1957, 1961, 1969, 1975.
