Space shuttles and Disasters

3. Essential Components
• Each Space Shuttle was a reusable launch
system composed of three main assemblies: the
reusable orbiter, the expendable External Tank, and
the two reusable Solid Rocket Boosters .
• Only the Orbiter entered orbit shortly after the tank
and boosters are thrown away. The orbiter was the
part that looked like an airplane,
• The external tank was a large fuel tank. Supplies
liquid nitrogen and oxygen to main engines
• The solid rocket boosters looked liked two thin
rockets. Provides 83% of total thrust needed for
launch
10. • Faulty wiring in the second
Oxygen tank caused fire due to
production of peroxide.
• They were losing oxygen and
fuel and were flying into outer
space at 2000 miles/hour.

13. • Would mean using the front side of
the engine, closest to the
explosion.
• Any error would make the space
shuttle crash on the moon.
• Required more fuel and oxygen
and other resources.
• On the occurence of even the
slightest error, the crew men would
be stranded in space.

17. • The Challenger Space Shuttle
exploded on January 28, 1986
• Caused by an O-ring failure
• All 7 crew members perished
The crew members:
Ellison S. Onizuka,
Sharon Christa McAuliffe,
Greg Jarvis, and Judy Resnik.
Michael J. Smith, Dick Scobee,
and Ron McNair.

19. President Ronald Reagan appointed a
special commission to determine what
went wrong with Challenger and to
develop future corrective mea
sures.
• After the accident, NASA refrained from
sending astronauts into space for more
than two years .
• In September 1988 , successful launching
of Discovery.
20. • Communication is key
• Only operate in tested conditions
• Safety over schedule.
22. • Named after Robert Gray’s
Columbia Sailboat.
• 1st operational space shuttle in
NASA’s orbital fleet on April
12,1981.
• It’s final and most popular space
mission was it’s 28th flight.
23. 1. 1ST February 2003.
2. STS-1:The operational orbiter.
3. About to reach the Earth within 16 minutes.
4.Control room of Florida’s Kennedy Space Center and 7 crew members
24.
25. • The flight started on 16th
January.
•NASA suspected damage
to the shuttle but no major
investigation.
•Left wing struck by piece
of foam.
27. >_ NO MORE OF NASA’S SPACE
SHUTTLES
• NASA has stopped manufacturing space shuttles since
2011.
• NASA’s last space shuttle Atlantis landed on 21 July,2011
• NASA has revealed that Boeing and SpaceX will build
America's first private spacecraft to ferry astronauts to
and from the International Space Station.
28. PRIVATE COMPANIES IN
THIS FIELD
• Space Exploration Technologies (SpaceX)
• Orbital Sciences
• Blue Origin
• Bigelow Aerospace
• SpaceDev/Sierra Nevada Corp.
• Virgin Galactic
29. SPACEx
• Founded by Elon Musk, SpaceX has
manufactured the Dragon spacecraft and
Falcon 9 rocket.
• The Dragon V2 shuttle developed by
SpaceX is capable of launching up to seven
astronauts into orbit.
• Acccording to NASA, it is one of two craft
selected to begin
shuttling astronauts to the International
space Station in 2017.
• SpaceX's Falcon 9 rockets and Dragon
spacecraft are initially expected to be
unmanned vehicles to serve NASA's cargo
needs for the International Space Station.
30. MORE ABOUT ITS PLANS
• SpaceX is planning to start a 1-
million person colony on Mars.
• That plan centers on the
Interplanetary Transport System
(ITS), which would consist of a
superpowerful reusable rocket and
a spaceship capable of ferrying at
least 100 people to the Red Planet
per flight.
