1. 2.1 Getting There: Technologies in Space Transport
Robotic space probes have investigated all planets except Pluto!
To launch an object into space, you must overcome Earth’s gravity with a speed of 28,000 km/h!

10. Between 1959 and 1971, NASA spacecraft were dispatched to study the Moon
They also scanned the inner planets Earth, Mercury, Venus and Mars.

11. Later in the 70’s various pioneer and voyager space crafts were sent to take images of Jupiter, Saturn, Uranus and Neptune and then later Mars and Venus

15. NASA Manned Space Flight History

16. Project Mercury Initiated in 1958, completed in 1963, Project Mercury was the United States' first man-in-space program.

17. Project Gemini The second U. S
Project Gemini The second U.S. manned space program was announced in January Gemini involved 12 flights, including two unmanned flight tests of the equipment.

First rendezvous in space

18. Project Apollo
It all started on May 25, 1961, when President John F. Kennedy announced the goal of sending astronauts to the moon before the end of the decade.
Six of the missions -- Apollos 11, 12, 14, 15, 16 and went on to land on the moon, studying soil mechanics, meteoroids, seismic, heat flow, lunar ranging, magnetic fields and solar wind. Apollos 7 and 9 tested spacecraft in Earth orbit; Apollo 10 orbited the moon as the dress rehearsal for the first landing. An oxygen tank explosion forced Apollo 13 to scrub its landing, but the "can-do" problem solving of the crew and mission control turned the mission into a "successful failure."

19. Apollo-Soyuz The mission started with the Russian Soyuz launch on July 15, 1975, followed by the U.S. Apollo launch on the same day. Docking in space of the two craft occurred on July 17, and joint operations were conducted for two full days. Both spacecraft landed safely and on schedule.

22. 3 Basic Parts of a Rocket
Structural and Mechanical Elements are everything including the rocket, engines, storage tanks and fins on the outside.
Fuel includes any number of materials such as liquid oxygen, liquid hydrogen and gasoline.
Payload includes the materials needed for the flight such as crew cabins, food, air, water, people and equipment.

23. The Future of Space Travel
1. Ion Drives
Engines that use Xenon gas that is electrically charged, accelerated, then emitted as exhaust.

24. Thrust generated by an ion drive is 10 000 times weaker than today's chemically fuel rockets,
however the force generated lasts a very long time and uses very little energy.

25. In space a little amount of force goes a long way.
Ion drives may be useful when traveling great distance in space.
The technology has already been tested by NASA’s Deep Space 1 Space Craft.

26. 2. Solar Sails
The sun emits electromagnetic energy in the form of photons.
The carbon fiber solar sail would catch these photons and potentially propel a space craft up to 5 times faster than current space crafts.

27. NASA has successfully tested deployment technologies on small scale sails in vacuum chambers.
No solar sails have been successfully used in space as primary propulsion systems, but research in the area is continuing.

28. Three types of spacecraft in use:
1. Shuttles – transport personnel and equipment to orbiting spacecraft.
2. Space probes – contain instrumentation for robotic exploration of space
3. Space stations – orbiting spacecraft with living quarters, work areas and support systems needed to work and live in space.

29. 3. The International Space Station
Currently orbiting the earth at an altitude of 350 Km.
Joint project between 16 nations including the USA, Canada, Japan, Russia, and Brazil as well as 11 European Nations.
Construction of the space station continues.

30. The space station is in a Low Earth Orbit, and can be seen from Earth with the naked eye.
It orbits at an altitude of approximately 350 km above the surface of the Earth travelling at an average speed of 27,700 km/h completing 15.7 orbits per day.

31. 4. The Next Step
Scientists believe the best place to begin an interplanetary flight is from a space station or even the moon.

32. 2.2 Surviving There: Technologies for Living in Space

33. Outside of the Earth’s thin atmosphere lies the cold vacuum of space.
An environment hostile to humans in many ways.
NASA is close to having the technology to send humans to Mars and back, however, a mission like this would take 2-3 years!

34. A. Hazards of Living in Space
Environmental Hazards
Space is a vacuum
No food, no water, no air!
Extreme temperatures
Cosmic radiation
Risk of being struck by meteoroids
No atmospheric pressure to regulate heart rates

35. Psychological Challenges to Confined Living:
Close, confined quarters for long periods of time.

36. Effects of Microgravity on the Body
In conditions of weightlessness the body undergoes many changes: bones expand, muscles atrophy (weaken) and heart rate is affected.

37. In space an astronaut is almost completely weightless
On Mars an astronaut would weigh 1/3 of what he/she weighs on Earth.
Weightlessness

38. 4 features needed to live in space
1. clean water 2. breathable air 3. comfortable temperatures and air pressure 4. source of power

39. B. Recycling Water in Space
The International Space Station will be using a device that can recycle almost 100% of the water on the space station (including waste water, water for hygiene and water in the atmosphere).

40. The ECLSS (Environmental Control and Life Support System) Water Recycling System (WRS), will:
reclaim waste waters from the Space Shuttle's fuel cells, from urine, oral hygiene and hand washing, and by condensing humidity from the air.
recycle water to produce oxygen
Remove CO2 from the air
Filter microorganisms and dust from the air
Keep air pressure, humidity and temperature stable
Without such careful recycling 40,000 pounds per year of water from Earth would be required to resupply a minimum of four crewmembers for the life of the station.

41. Not even research animals are excused from the program.
"Lab animals on the ISS breath and urinate, too, and we plan to reclaim their waste products along with the crew's.
It might sound disgusting, but water leaving the space station's purification machines will be cleaner than what most of us drink on Earth.
"The water that we generate is much cleaner than anything you'll ever get out of any tap in the United States," says Carter. "We certainly do a much more aggressive treatment process. We have practically ultra-pure water by the time our water's finished."

42. C. Producing Oxygen in Space
Electrolysis uses electricity to split water into hydrogen and oxygen.
The hydrogen is vented into space.
The oxygen produced can supply most of the crews needs.

44. D. Space Suits
Must supply air, water, a heating and cooling system, and even a portable toilet.
Must be flexible and allow movement.

49. Satellites – objects built and sent into Earth’s orbit by humans.
Artificial satellites: man-made objects sent out into orbit.
Natural satellites: Any small body that orbits a larger body, eg. Moons.

51. Uses of Satellites Observation/Research Communication
Observe/predict weather
Observe/predict magnetic storms
Location
T.V.
Long distance phone calls

52. A geomagnetic storm is a temporary disturbance of the Earth's magnetosphere caused by a disturbance in space weather.
a geomagnetic storm is caused by a solar wind shock wave which typically strikes the Earth's magnetic field 24 to 36 hours after the event.
Magnetic storms usually last 24 to 48 hours, but some may last for many days.
In 1989, an electromagnetic storm disrupted power throughout most of Quebec — it caused auroras as far south as Texas.

54. Geosynchronous Orbit Satellite moves at same rate Earth spins.
Satellite is always positioned over same location on Earth.
Geosynch video

55. Low Earth Orbit 200 – 1000 Km in altitude
Usually used for remote sensing (taking images to make observations of the Earth)

56. GPS Global Positioning System
24 global positioning satellites orbit the Earth which means that at least 3 are above any given location on our planet at any given moment.
Radio signals from the satellites are picked up by GPS units and the users location is triangulated.
