What you’ll learn

  1. Explain how rockets reach space and name key firsts: Sputnik, Gagarin, and the Moon landing.Rockets use powerful thrust to escape Earth's gravity. Sputnik 1 (1957) was the first satellite, Yuri Gagarin (1961) was the first human in space, and Neil Armstrong (1969) was the first person on the Moon.
  2. Describe life in space, the ISS, space robots, and the future of exploration.Astronauts float in weightlessness and live aboard the International Space Station. Robots explore distant worlds like Mars. Future rockets and missions aim to return people to the Moon and reach Mars.

Questions this course answers

Why do we use rockets to reach space?

Rockets create powerful thrust to push against Earth's gravity and reach the speed needed to enter space.

What was Sputnik 1, launched in 1957?

Sputnik 1 was the first artificial satellite, launched by the Soviet Union in October 1957.

Who was the first human to travel into space?

Yuri Gagarin became the first human in space on April 12, 1961, aboard Vostok 1.

Why do astronauts float inside a spacecraft?

In space there is almost no gravity, so astronauts experience weightlessness and float around.

What is the International Space Station (ISS)?

The ISS is a laboratory orbiting Earth, built and used by many countries working together.

Why do we send robots and probes to places like Mars?

Robots can explore distant or dangerous places that people cannot easily reach yet, sending discoveries back to Earth.
