Apollo 13 was the seventh manned mission in the Apollo space program and the third intended to land on the moon.
The craft was launched on April 11, 1970 but the lunar landing was aborted after an oxygen tank exploded two days later, crippling the service module (SM) upon which the command module (CM) had depended.
Despite great hardship caused by limited power, loss of cabin heat, shortage of portable water and the critical need to make makeshift repairs to the carbon dioxide removal system, the crew returned safely to Earth on April 17, 1970, six days after launch.
Hang Psalm 20 on the Apollo 13 moon mission
May the Lord answer you in the day of trouble!
May the name of the God of Jacob protect you!
2 May he send you help from the sanctuary
and give you support from Zion!
3 May he remember all your offerings
and regard with favor your burnt sacrifices! Selah
4 May he grant you your heart’s desire
and fulfil all your plans!
5 May we shout for joy over your salvation,
and in the name of our God set up our banners!
May the Lord fulfil all your petitions!
6 Now I know that the Lord saves his anointed;
he will answer him from his holy heaven
with the saving might of his right hand.
7 Some trust in chariots and some in horses,
but we trust in the name of the Lord our God.
8 They collapse and fall,
but we rise and stand upright.
9 O Lord, save the king!
May he answer us when we call.

May the Lord answer you in the day of trouble!
