1) No, they continued on route to the moon and used the gravity of the moon to swing

around and get ac! to earth" #iring the roc!ets and reversing would use u$ too much

fuel and they would not have reached earth"

%) &he angle was im$ortant ecause if the angle was wrong then they could have

urned u$ or ounced o' once hitting the earth(s atmos$here"

3) &here was a damaged coil in the oygen tan! that was uilt two years efore *ovell

was named +ight commander, so when ac! went to stir the tan!s they e$loded" -

ho$e that in further s$ace missions, the e.ui$ment is thoroughly eamined efore

+ight"

4) e learned that it is not ad to chec! e.ui$ment multi$le times and y multi$le

$eo$le"

0) - thin! that this is ecause we have lost interest in the moon" -t(s too close to us and

we have sort of moved on, our focus eing shifted to nding haitale $lanets" - thin!there should e more missions to the moon ecause e$loring the moon is eciting

and interesting"

2) &hey were unale to communicate with mission control at the end when they went

into the earth(s atmos$here ecause they were going really fast and lost radio once

they hit the atmos$here"

) Most of the training too! $lace in the simulator" ne of the training eercises was

that 5wigert had to doc! the dyssey onto some console, stimulating an actual event

that they would do in s$ace" -f - were creating eercises, - would incor$orate ones that

involve getting safely to earth under ad circumstances"

6) &hey were losing oygen, there was too much caron dioide in the s$aceshi$, and

there was not enough fuel left for them to return to earth using the normal $rocedure"

-n order to the oygen $rolem, they had to turn o' one of the tan!s" &o the

caron dioide $rolem, they had to create a contra$tion and cover the oygen tan!s

with it to lter the air" &o solve the fuel $rolem, they had to $ower down everything

and ma!e sure they were aligned manually"

7) - don(t really !now what was going on during the doc!ing $rocedure, ut - guess

that it stailized the s$acecraft"

18) &he need for the recalculation was that the *9M was made to only handle two

$eo$le not three" &he additional $erson throws o' the amount of oygen eing inhaled

and shortens how long all three of them will e ale to last in the *9M"

11) :$on reentry of the 9arth(s atmos$here, the *9M started getting hotter and

defrosting" &he astronauts were calm, ut - would not have een as calm ecause -

would e scared of $ossily dying"

1%) &hey had to use $hysics to tal! aout the tra;ectory of the craft and it(s eing

aligned with the $ro;ected $ath"

13) A$ollo 13 was a successful failure ecause while they were not ale to land on the

moon and they had huge $rolems with the s$ace craft, it was a success ecause they

<ed< the $rolems and arrived ac! home"
