put men on the moon
put satellites in orbit
tested new escape hatches
put men in space
11
What 2 changes impact the MARK III spacesuit?
allows entry from the rear of suit & to kneel
thermal layers & protective gloves
it is no different
an oxygen system & visor
12
Why were Apollo missions cancelled?
12 astronauts died on the moon
humans couldn't breathe on the moon
too expensive due to NASA budget cuts
spacesuit weren't good enough
13
What was a major limitation of the spacesuits during the Mercury missions?
if pressurized they could not move their heads
did not keep them warm enough
suit was too heavy
they could not see out of the visor
14

regulate temperature
protect from radiation
trap excessive CO2
provide pure O2
15
How does the spacesuit backpack help astronauts breathe in space?
collects urine & waste
provides pure O2 and collects CO2
maintains air pressure to keep body from boiling
stabilizes internal temperature

17
Which of the following is NOT a reason for full-scale mock-ups
master all aspects of flight operations by crew
discard out-of-date technology
familiarize crew with escape procedures
to guarantee maximum safety & lessen expense
18
