How does a person become an astronaut?

• You have to be 64" to 76" tall
• Be a geologists, physicists, chemists, biologists
  etc.
• Must have a bachelors from an accredited
  institution.
• Have a distant visual acuity no greater than
  20/50 uncorrected, correctable to 20/20
• Blood pressure, while sitting, must be no greater
  than 140 over 90
• Must have had at least l,000 hours flying time in
  jet aircraft
• Must be citizens of the United States.
• A bachelors degree in engineering, biological
  science, physical science or mathematics is
  required

What is a Cosmonaut?

• "Cosmonaut" refers to a member of the Russian
  cosmonaut corps who have been designated by
  agreement to fly as crew members aboard U.S.
  spacecraft.
• Russia is also a partner of the I.S.S.
  (International Space Station)
• The United States and Russia together man the
  I.S.S., rotating mission responsibilities

5
Responsibilities of Astronauts

• To serve as both space commanders and pilots.
• Commander has onboard responsibility for the
  vehicle, crew, mission success, and safety of
  flight.
• Pilot assists the commander in controlling and
  operating the vehicle and deployment. Also
  assists in retrieval of satellites using the
  remote manipulator system (RMS), referred to as
  the robot arm or mechanical arm
• Payload specialists are persons other than NASA
  astronauts (including foreign nationals) who have
  specialized onboard duties. They may be added to
  shuttle crews if missions have unique
  requirements
• Mission specialists work with the commander and
  the pilot. Have overall responsibility for
  coordinating operations. Also perform
  extravehicular activities (EVAs), or space walks,
  operate the remote manipulator system, and are
  responsible for payloads and specific experiment
  operations

6
How Do Astronauts Breath in Space?

• 100 oxygen preparation before space walk
• mixture includes 20 nitrogen, 80 oxygen

STS-98
7
How long is an average space walk?

• The average space walk is between 5 to 7 hours

8
Layers in the EMU

• Each EMU consists of 14 layers to protect the
  astronaut fully.

STS-99
9
Parts of an EMU

• liquid cooling and ventilation garment
• oxygen pack
• lower torso assembly
• hard upper torso
• primary life support system
• helmet

10
What makes a protective EMU?

• Light weight nylon
• neoprene-coated nylon
• nylon for pressurized layers
• aluminized Mylar
• 2 layers of Kapton
• Teflon- coated cloth
• a layer of white Teflon cloth (nonflammable)

• water-cooled nylon undergarment
• multi layered pressure suite

11
How do astronauts keep up with tools in Space?

• NASA uses Velcro (along with a specially designed
  tool belt) to help astronauts keep up with their
  tools in space

Difference in EMU and MMU

• The MMU is a one man, nitrogen propelled backpack
  that latches to the EMU spacesuits PLSS, while
  the EMU would be considered the astronauts main
  spacesuit.

13
International Space Station

• A City Above the Clouds

14
People of the Space Station

• First crew took up residence on the I.S.S on
  October 31, 2000.
• As of February 2002, there has been 4 crews on
  the I.S.S.
• United States and Russia
• partners in operating/
• running the I.S.S.

15
Eating sleeping on the I.S.S.

• Space travelers also have irradiated meat

• Astronauts sleep in beds or seats, but they have
  to strap themselves to a wall, seat or bed.
• Our fearless space trekkers eat rehydratable
  foods, thermostabilized foods, intermediate
  moisture foods, or natural form foods

16
The Space Shuttle
STS-109
17
Names of shuttle/orbiters

• Columbia
• Challenger The Challenger exploded
• Discovery
• Atlantis
• Endeavor

STS-108
18
The types of fuel that a shuttle uses are

• ammonium perchlorate
• aluminum
• iron oxide
• a polymer
• an epoxy agent

STS-109
19
The main parts of a space shuttle are

• The Orbiter
• The Solid Rocket Boosters SRB
• The External Tank
• Cargo Bay
• Main Engine
• Crew Cabin

20
How does the Shuttle Land?

• The crew closes the cargo bay doors. Most likely,
  they have been flying nose-first and upside down,
  so they then fire the RCS thrusters to turn the
  orbiter tail first.
• Once they are tail first, they fire the OMS
  engines to slow the orbiter down and fallback to
  Earth it takes about 25 min. before you reach
  the upper atmosphere. (cont. next slide)

21
During that time, they fire RCS thrusters to
pitch the orbiter over so that the bottom of the
orbiter faces the atmosphere about 40 degrees
and they are moving nose first again. Finally,
they burn leftover fuel from the forward RCS as a
safety precaution because this area encounters
the highest heat of re-entry.
