Notes
Working in Space
•A space shuttle is a spacecraft that can carry people and objects into space. A space shuttle can then return to Earth and land like an airplane. A space shuttle can be used many times.
•A space station is a large satellite where people can live and work. The International Space Station is currently in orbit around Earth
Working in Space•Werner von Braun was one of the first
to suggest a reusable space transport in the 1950s.
•In 1972, President Richard Nixon announced the Space Shuttle Program.
•From April 12, 1981 to July 21, 2011, a total of five different shuttles flew 135 missions.
Working in Space• Columbia: Apr 12, 1981 - July 16, 2003
• - 28 Flights
• Challenger: Apr 4, 1983 - Jan 28, 1986
• - 10 Flights
• Discovery: Aug 30, 1984 - Feb 24, 2011
• - 39 Flights
• Atlantis: Aug 3, 1985 - Jul 8, 2011
• - 33 Flights
• Endeavor: May 7, 1992 - May 16, 2011
• - 25 Flights
Working in Space•On January 28, 1986, seven NASA
astronauts lost their life.
•73 seconds after liftoff, the space shuttle Challenger, exploded.
•Challenger was carrying what would have been the first teacher in space, Christa McAullife.
•No more space shuttle flights occurred for over 2 years after this tragic accident.
Working in Space
•On February 1, 2003, during re-entry, the space shuttle Columbia disintegrated, taking the lives of 7 astronauts.

Working in Space• All space shuttles were officially retired on
August 31, 2011.
• At this point there are no plans to reinstate the space shuttle program, but there are plans to build new machines in the future.
• American astronauts are allowed back and forth to the ISS through Russia’s space program.
• NASA is encouraging the private sector to develop technologies to help humans back into space.
Working in Space
•Space stations provide a place where long-term observations and experiments can be carried out in space.
•Both the Russians and the Americans have had space stations in orbit around Earth.
•Guess who got there first.

Working in Space• By far, the most famous space station was Mir,
placed by the Soviets in 1986. Mir translates to “Peace.”
• Both Americans and Russians would eventually work aboard Mir until it crashed 15 years after its launch, in 2001.
• Beginning in the 1980s, 15 countries began planning the construction of the International Space Station. The first module (piece) of the station was placed in orbit in 1998, and is still being constructed today.
• Consisting of 8 large solar panel arrays containing over 250,000 solar cells each, the ISS can generate enough power from the sun to light up over 55 houses on Earth.
Space Probes• A space probe is a spacecraft that carries
scientific instruments into space. The instruments collect information.
• No humans are on board a space probe.
• Some space probes land on other planets/moons/asteroids, while others will orbit them then leave.
• Some space probes carry small robots called rovers. These rovers have the ability to travel around on the surface of another object.
• Currently there have been missions to all planets.
