1. What do we have to overcome to be able to get an object into ​space?
What speed is necessary to do this?
The force of gravity pulling the object back toward Earth.
The speed necessary to do this is 28 000km/h.
2. What was the first rocket ever recorded?
Archytas's "pigeon" is said to be the first rocket ever recorded.

3. Describe the details surrounding the launching of the first
artificial ​satellite.
On October 4, 1957, the Soviet Union launched Sputnik I into ​orbit. It was
about the same size as a large basketball.
4. What was the significance of the second satellite that the Soviet ​Union
launched?
It was the first time any living creature had been sent into ​space. The
information gained from the mission set the path for ​human space travel.

5. What is the fundamental law
of physics that rocketry relies on?
For every action, there is an equal
and opposite reaction.
6. Sketch how this law of physics
applies to how a rocket
is ​propelled. (Refer to figure 2.7)

7. There are three basic
parts to a rocket. List
what these are in the
chart ​below along with a
description and a
breakdown in
percentages of how ​much
of the total mass it makes
up.

cross section of a rocket
(Figure 2.8)

9. Describe and sketch in the space below the two alternatives to ​rocket
engines that scientists are studying, especially for propelling ​spacecraft on
long journeys.
Ion Drive: use xenon gas instead of chemical fuels. The xenon is
electrically charged, accelerated, and then emitted as exhaust. This
action pushes the spacecraft in the direction opposite to the emission

long journeys.
Solar Drive/Sails: the photons hit the sail; the energy transmitted causes
the spacecraft to move

10. Name and provide a description of the three main types of ​spacecraft in
use.
Shuttles transport people and equipment to orbiting spacecraft.
Space probes contain instrumentation for carrying out robotic exploration of
space.
Space stations are orbiting spacecraft that have living quarters, work areas,
and all the support systems for living and working ​in space for long periods of
time.

11. What is the International Space Station and what purpose will it serve?
It is a space station built by the partnered effort of 16 nations ​(Canada,
United States, Japan, Russia, Brazil, and ll European ​nations.
It will serve as a permanent laboratory in space, as well as a ​command post
for building and launching interplanetary ​rockets.
