The information about challenger space shuttle launched by NASA it helps to slove ethical issues.

3. The study provides instructions in engineering ethics through a
case of space shuttle challenger disaster. The course begins by
presenting the minimum technical details needed to understand
the physical cause of shuttle failure .
The purpose of case studies in general is to provide us with the
context of the technical details of an engineering decisions in
which an ethical principle may have been violated.

5. Challenger was the name of NASA’S space shuttle .The
purpose of the shuttle was to make multiple trips and
launch satellites into space .Challengers was NASA’S
greatest triumphs.
It was the second shuttle to reach space. It is launched in
4th April 1983 it also completed nine successful
milestone missions, but challenger was also one of
NASA’S greatest tragedy on its 10th launch on jan
28,1986 shuttle was torn apart, its parts blew into
flames and fell off into water killing all seven of its
crew members and all happened just in 73seconds
after its flight.

9. For challenger in its
10th mission has
many problems
from the beginning.
One day before the
launch the
temperature in
central Florida is 37f
which is very low

11. To understand that we have to understand the basic
structure of space shuttle. There are three basic
components in a space shuttle they are:
Orbiter: which holds the crew
External tank: That holds fuel for main engine
Solid rocket boosters: Provides lift during the first
two minutes.
This happened because the space shuttle external
fuel tank is collapsed releasing all its liquid to
create a giant fireball thousands of feet in air .

14. They said that it was a cold morning on the day of
launch below freezing point . In such conditions some
parts of the shuttle particularly the o-rings are unsafe
to use .There was no prior experience for NASA to
launch shuttle in such conditions.
Richard Feynman concluded at final meeting that
“CHALLENGER IS A MAN MADE DISASTER WHICH
DIDN’T HAVE TO HAPPEN”.

15. The function of o-rings is to
seal the joints so tightly that
they prevent violently hot
gases from escaping . They
stopped working and
became brittle in low
temperatures . They starts
working when gas leak is
observed but they failed to
seal the gas at low
temperatures.

16. They cancelled all the shuttles till 1988
Solved the problem of o-rings by keeping a heat pad to
make sure that they work properly no matter who cool
it is outside.
