Rocket Program
Mercury Rocket
•Robert Goddard is the
“Father of Modern Rocketry”.
•National Aeronautics and
Space Administration (NASA)
formed in 1958. Combined all
the separate rocket programs
into one program.
•Mercury was one of the
earliest rockets.

Artificial Satellites
Launch of Satellite
•An artificial satellite is
any human-made object
placed in orbit around a
body in space.
•Low Earth Orbit (LEO)
satellites orbit Earth very
quickly.

Artificial Satellites
Satellite
•Geosynchronous Orbit (GEO)
satellites travel around the
Earth at a speed that matches
the Earth’s rotational speed.
•GEO satellites will remain
positioned about the same
spot at all times.
•An example would be
communication satellites.

Hubble Space Telescope
Not all satellites look down on Earth. Among
the most important satellites to astronomers
is the Hubble Space Telescope which looks
out toward the stars.

The Galaxy 28 million light years
from Earth has 800 billion suns and
is 50,000 light years across.

The Ant Nebula lies with our galaxy
between 3,000 and 6,000 light
years from Earth.

The Eskimo
nebula because
it looks like a
face surrounded
by a furry hood.
The hood is a
ring of comet-
shaped objects
flying away from
dying star. It is
5000 light years
away from Earth.

The Cone
nebula is 2.5
light years in
length
(equivalent
to 23 million
round trips to
the Moon.

This section of the Swan Nebula is known as the
Perfect Storm is described as a bubbly ocean of
hydrogen and small amounts of sulphur, oxygen,
and other elements.

Night is a
halo of light
around a
star in the
Milky Way
galaxy.

Two merging eye from 114 million
light years away are the cores of
two merging galaxies.

The Trifid
Nebula is a
nursery
where new
stars are
born. It is
9,000 light
years from
here.

Space Shuttle
Launch of Space Shuttle
•A space shuttle is a
reusable vehicle that
takes off like a rocket
and lands like an
airplane.
•First shuttle was
launched in 1981 and
was followed by two
dozen successful
missions.

Space Probes
Magellan Probe
•A space probe is a
vehicle that carries
scientific instruments
to planets or other
bodies in space.
•Space probes travel
away from the Earth
and give us our first
encounters with other
planets and moons.

Space Probes
Voyager 2 Probe
•Space probes are usually
sent on one-way missions.
They do not return to
Earth.

Space Probes: Viking Mission
Viking Probe picture of
Mars’s surface.
•In 1975, space probes were sent to Mars to
look for signs of life.
•The Viking probes did find evidence that
Mars was once much warmer and wetter
than it is now.

Space Probes: Pioneer Mission
The Pioneer 10 and 11 space
probes were the first to visit the
outer planets.
They sent back information
about the rings around
Jupiter.
Today they are near the
edge of the solar system
and still sending back
information.

Space Probes: StarDust
•Launched in 1999 as the first probe to focus
only on a comet.
•Arrived at the comet in 2004 and gathered
samples of the comet’s tail.
•Material arrived back to Earth in January,
2006.
•First time that material
beyond the orbit of the
moon has been brought
back to Earth.

Space Stations •A space station is a long-term orbiting
platform from which other vehicles can be
launched or scientific research can be carried
out.
•The US and Russia
launched the first parts
of the International
Space Station in 1998.
•People have been
working and living
on the ISS since 2000.

Benefits of the Space Program
• Smaller radios, computers, and televisions
made for use in space are now used on
Earth.
• Freeze-dried foods were first developed
for use by astronauts.
• Lightweight, fireproof clothing, nonstick
cookware, and sunglasses are all space
benefits.
