Who the astronauts are
Risk to human life in space
Purpose of training of astronaut
Types of events in space
Phases of training of astronaut
The term "astronaut” is derived from the Greek words
astron, meaning "star", and nautes, meaning "sailor".
An astronaut or cosmonaut is a person trained by a
spaceflight program to lead, pilot or be a crew member of
an expedition to space on a spacecraft.
As well as being used to describe a professional space
traveler, the term astronaut or cosmonaut is now often
used for anyone who travels into space, such as scientists,
politicians, journalists, and tourists.
Humans are psychologically well-adapted to
life on earth. Consequently, spaceflight has
many negative effects on the psychology.
Increased radiation levels
Loss of bone
Effect of weightlessness
Disruption of vision , taste .
Fatigue and sleep loss
It describes the complex process of preparing
astronauts for their space missions before, during
and after flight, which includes
extra-vehicular activity (EVA) training,
rehabilitation process, as well as training on
experiments they will accomplish during their stay
For these types of missions the training to
prepare astronauts will likely include training as
doctors, scientists, engineers, technicians, pilots,
The astronauts are prepared for two types of events ;
During training, astronauts are familiarized with the
engineering systems of the spacecraft.
In addition to this, astronauts receive training in
orbital mechanics, scientific experimentation, earth
observation, and astronomy.
Training is performed in order to prepare astronauts
for events that may pose a hazard to their health, the
health of the crew, or the successful completion of the
External events refers more broadly to the ability
to live and work in the extreme environment of
space. This includes adaptation to microgravity
The difficulty associated with living and working
in microgravity include spatial disorientation,
motion sickness, and vertigo.
During long-duration missions, astronauts will
often experience isolation and confinement. This
has been known to limit performance of astronaut
crews and hence training aims to prepare
astronauts for such challenges.
After completion of Basic Training candidates
proceed to NASA's Advanced Training.
These candidates are called AsCans (astronaut
Phase 1 : personal training
Phase 2: group training
Phase 3: technical training
The first phase starts with two years of basic
training. Much of this training takes place in
the classroom, where astronaut candidates
learn about vehicle and space station systems.
They also study key disciplines -- including
earth sciences, meteorology, space science and
Outside the classroom, astronaut candidates
must complete military water- and land-
survival training to prepare for an unplanned
landing back on Earth.
They must swim three lengths of a 25-meter
(82-foot) pool without stopping.
• It's really just the beginning of the second phase. In
this phase, astronaut trainees are grouped with
experienced astronauts, who serve as mentors to
share knowledge and experience.
• The ultimate goal of this mentoring relationship is to
make sure each trainee is proficient in all activities
related to pre-launch, launch, orbit, entry and
Finally, in the 3rd phase, astronauts receive their
mission and crew assignments, entering what is
known as the advanced mission training phase.
In this final 10-month training period, astronauts
focus on activities, exercises and experiments specific
to their mission.
. For example, astronauts assigned to the STS-61
mission were tasked with fixing the optics of
the Hubble Space Telescope.
It is conducted in KC-135
four engine jet
It is able to provide 30
second of weightlessness
To perform the mission in the
astronaut has to go outside
the space shuttle.
To do this astronaut pass many
hours to practice the space walks
It is just like to float in water
To practice the space motion
large pools are used.
The world’s biggest indoor
pool is also used for this
This is made to
of space on the
earth to the AsCan
Preparation for emergency
It is conducted to prepare
an AsCan for emergencies
e.g technical problem in
Space shuttle , lack of
communication , aliens etc
Long duration missions aboard ISS last from 3
to 6 months and take about 2 to 3 years of
increment specific training.
For missions to the ISS, each astronaut is
required to become proficient at one hundred
or more experiments.
Astronaut suit is of 28 pounds on earth and
almost weightless in space.
