2.1 Getting There: Technologies for Space Transport pg. 408-417)

Challenges of Space Travel• going fast enough to break free of Earth's ____________ (at least __________ km/h).• develop reliable spacecraft that can withstand _____________, small celestial particles and extreme ________________.• keep equipment _____________ in space• transport people _________

Satellites circle the Earth and provide information for: ••••

Robotic space probes have visited all planets except ________.

UNIT E

Developing Rocket Boosters1. 400 BC ­ escaping _________ propelled a model pigeon along a wire.

2. 1st century AD ­ _____________ was used to make rocket propelled arrows.The first small satellite (__________) was launched by the Soviet Union.

The first living thing into space was a small ______.  Human space travel was next. (______)

Parts of a Rocket1. _____________________________ ­ rocket, engines, storage tanks, and fins.2. ________ ­ may be liquid O2, gasoline, or liquid H2. This is ignited in a combustion chamber, the gases expand and leave as exhaust.3. _____________ ­ materials for flight including crew cabins, food, air, water, and PEOPLE!

Rockets continued...Law of Physics: For every action, there is an equal and ____________ reaction.

Example:A balloon with air contains a gas under pressure.  When the gas is released, the balloon _________ in the opposite direction.

Reaction (movement)

Action (released gas)

The same movement or __________ is used in a rocket.

The Future of Space Technology1. ______________ ­ engines that use _________ gas instead on chemical fuels.

Advantages Disadvantages• thrust lasts a _______ time• fuel amount is _____________ to one tenth.• in space, a little force over a long time results in a _______ vehicle.

• an extremely _______ thrust is produced

2. ________________ ­ use the sun's emitted electromagnetic energy to cause ______________.  The initial proposal is to create them as thin as plastic wrap and 400m2 to increase space travel ________.

Types of Spacecraft• _____________ ­ transport people and equipment. Must include an internal liveable atmosphere.• ___________________ ­ instruments for robotic exploration.• ___________________ ­ orbiting spacecraft with living and working space. Must include an internal liveable atmosphere.

Next StepsInterplanetary Journey ­ start from the ________ or space station so that gravity would not be an issue.______________________________ (ISS): a joint project between _____ countries.It includes a permanent lab to study, build, and launch ___________.

The total work area is about the size of 3 average ________.

Other InformationThe Apollo Missions led to creating _________ duration space missions.

Further space development includes more space stations and creating ________________ space shuttles.QUESTIONS1. Which was the first country to launch an artificial satellite?

2. Describe the 3 basic parts of a rocket, and draw and label a sketch showing the parts. (see pg. 412).

3. Name 2 alternatives to rocket engines that scientists are studying and 1 advantage for each.

4. Explain what would happen if a rocket's payload were greater than the allowed percentage.
