  1. - Web Quest Crew Matt-Mission Director Daniel-Space Station Manager Michael-Navigator Bo-EMU Specialist


  3. 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

  4. 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 Microscopic view of velcro

  12. Difference in EMU and MMU The MMU is a one man, nitrogen propelled backpack that latches to the EMU spacesuit’s PLSS, while the EMU would be considered the astronaut’s 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. 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 • Space travelers also have irradiated meat

  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. STS-108

  22. I.S.S. Parts From The World Brazil: Express Pallet Italy: Multi-Purpose Logistics Module Canada: CSA Remote Manipulator System Europe: European Lab- Columbus Orbital Facility Japan: Japanese Lab- “Kibo” (Hope) Russia: Science Power Platform, Docking/Stowage Module, Universal Docking Module Zvezda (star) Service Module United States: Truss, US Lab- “Destiny”, Crew Return Vehicle, Airlock, Thermal Control Panels, Photovoltaic Arrays

  23. The responsibilities of each mission do change from S.T.S. mission to mission Yes Hi! Expedition 4 - I.S.S.
