A presentation on Space Shuttles, Types, and the worst space shuttle disastors including the Apollo 13 mission, Challenger disaster and Columbia. Also includes a brief introduction of spacex and the difference between space shuttles and rockets.
• 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

production of peroxide.
• They were losing oxygen and
fuel and were flying into outer
space at 2000 miles/hour.

shuttle crash on the moon.

and other resources.
• On the occurence of even the
slightest error, the crew men would
be stranded in space.

• The Challenger Space Shuttle
exploded on January 28, 1986

• All 7 crew members perished
The crew members:

Greg Jarvis, and Judy Resnik.
Michael J. Smith, Dick Scobee,
and Ron McNair.

>_ NO MORE OF NASA’S SPACE
• NASA has stopped manufacturing space shuttles since
• 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.
PRIVATE COMPANIES IN
• Space Exploration Technologies (SpaceX)
• Orbital Sciences
• Blue Origin
• Bigelow Aerospace
• SpaceDev/Sierra Nevada Corp.
• Virgin Galactic
• 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.
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
