This document provides a brief history of space exploration from the 20th century to today. It outlines 3 major events: the first orbital space flight by Sputnik 1 in 1957, the first human spaceflight by Yuri Gagarin in 1961, and the first moon landing by Neil Armstrong in 1969. It also lists important dates in space exploration and looks ahead to potential future developments like space tourism and colonizing other planets to ensure humanity's long-term survival.

2. 1. Little history.
2. Three major events of the space.
3. Big dates.
4. Vision of future.

3. The exploration of the solar system is the first step of the
conquest, one of the major events of the second half of the 20th
century.

4. Thanks to the German breakthroughs
during the Second World War,
particularly in rockets improvements, the
conquest of space quickly took off.
It was marked at the beginning by
strong competition between the United
States and the USSR, national prestige
reasons related to the Cold War.
This period was called the space race.

5. During the second half of the
20th century,
with the development of
appropriate means of
propulsion, new electronic
components, the development
of the industrial devices,
sending a mission into the
space was no longer just a
dream but a reality.

6. The first orbital space flight on
October 4th, 1957 by the Soviet
satellite Sputnik 1
The first flight inhabited by a
human being on April
12th, 1961 with
the orbital flight of the Soviet
Yuri Gagarin
The first step on the Moon
on July 20, 1969 by astronaut
Neil Armstrong

German V2 missile is the first artificial object to
reach an altitude of 100 km
• October 4th, 1957:
Small Soviet satellite Sputnik 1 becomes the first
object orbited by humans.
• November 3rd, 1957:
Russian dog Laika, first living animal to achieve
an orbit in space.
• October 1st, 1958:
Creation of NASA, the spatial agency of the
USA.

8. • April 12th, 1961:
First Human sent into space for an
orbital flight, Russian Yuri Gagarin,
during the Vostok 1 mission.
• May 5th, 1961:
Alan Shepard becomes the first
American in space during
the Mercury-Redstone mission 3.
• December 14th, 1962:
First flight over another planet, Venus,
by the American probe Mariner-2.
• June 16th, 1963:
First woman in the space,
Valentina Terechkova

9. July 21st, 1969
First steps on the
Moon during the
Apollo 11 mission,
directed by
Neil Armstrong
and Buzz Aldrin.

10. • May 31st, 1975
Creation of ESA, the European
spatial agency
• 1990
As a result of a collaboration
between NASA and ESA, the
Space Telescope has made many
advances in the understanding of
the Universe.
• April 28th, 2001
Dennis Tito, first tourist in the
space.

11. • January 14th, 2005
European probe Huygens lands on Titan.
• December 21st, 2015
First vertical landing of an orbital rocket,
the Falcon 9.

12. The discovery of
new worlds has always
nourished the
men’s imagination.
Human beings remain
moved by a powerful
fascination for the
unknown.

13. "Since we left Africa to
explore the world, our
thirst for travel and
discovery has remained
intact”
according to Marcello Coradini,
Chairman of the Scientific Committee
the French Research Agency and
Director of Space Programs of the
European Space Agency.

14. A real space market has opened and may one day
prove capable of being self-financing.
Because the challenge does not exclude profit.
Space tourism could indeed bring money, as the
exploitation of the subsoil of the stars of our solar
system, which seems to harbour precious
minerals. But to conquer the space is also, for
some, the only way to save the human race.

15. An option defended notably by the famous astrophysicist Stephen Hawking, who died last March.
Faced with the likelihood of the future disasters (climate change, genetically modified viruses, nuclear war),
the author of "A Brief History of Time" was convinced that mankind should, within a hundred years, start
migrating to other planets and maybe we could even go there with flying cars.
