One Moon

• - Moon, Name Given To This Natural Satellite
  That Orbits The Earth.
• - Mass Of The Earth Is 81 times Greater Than
  The Moon.
• - The Moon Has No Water, No Atmosphere, And No
  Weather On Its Surface.

3
One Moon

• - The Moons Average Distance From The Earth Is
  238,857 Miles
• - It Travels At An Average Speed Of 2,300 Miles
  Per Hour.
• - The Moon Completes One Revolution Around The
  Earth in Approximately 27 Days, 7 Hr., And 43
  Minutes.

Satellites

• Satellites , placed into orbit around the earth
  and used for a variety of scientific and
  technological purposes.

The first artificial satellite, Sputnik 1, was
launched by the Union of Soviet Socialist
Republics (USSR) on October 4, 1957.

Satellites

• The first United States satellite, Explorer 1,
  was launched on January 31, 1958, and was
  instrumental in the discovery of the radiation
  belts around the earth.
• In 1983, the European Space Agency began
  launching from a space center in French Guiana.

Satellites
Communications Satellite The Syncom 4
communications satellite was launched from the
space shuttle Discovery. Modern communications
satellites receive, amplify, and retransmit
information back to earth, providing television,
telefax, telephone, radio, and digital data links
around the world.

Debris In Outer Space

• Today, more than 9,000 objects are being tracked.
  In addition, there are more than 100,000 bits of
  debris too small to follow. Then there are even
  tinnier particles slipping through space, and
  they number in the tens of millions.
• From paint chips and lens covers to discarded
  space reactors and spent rocket stages, after
  four decades of heaving satellites into Earth
  orbit, space has become a polluted junkyard.

Debris In Outer Space

• New data compiled by the Aerospace Corp.s Center
  for Orbital and Re-entry Debris Studies in El
  Segundo, Calif., found that more than 425,000
  pounds of material re-entered Earths atmosphere
  in 1999.
• 84,000 pounds of that total survived
  re-entry.Since 25 percent of Earths surface is
  land, CORDS estimates that 21,000 pounds (9,500
  kilograms) actually struck land.

Debris In Outer Space

• On Jan. 24, 1978, a Soviet Cosmos 954 deorbited
  and slammed into Canadas Great Slave Lake area
  of the Northwest Territories. Making matters
  worse, that radar-snooping spacecraft was powered
  by a nuclear reactor.
• In July of the following year, the U.S. Skylab
  space station bowed out of Earth orbit. It
  weighed a massive 77 tons. Huge pieces of Skylab
  fell through Australian skies, creating visual
  effects, even sonic booms, as debris passed
  overhead.

Debris In Outer Space

• To better help satellite and rocket builders,
  CORDS welcomes any space debris that may be
  picked up by the public. Understanding how and
  why space hardware can survive the fiery fall
  from space is challenging.
• By recovering and studying space debris,
  knowledge can be gained about how and why
  satellites and rocket parts beat the heat. That,
  in turn, can help manufacturers design in ways
  that lessen the chance of future space hardware
  making it to Earths surface.
