190/1200 KM orbit - second stage will drop off here
jump to 1400km altitude - last went on Apollo missions
avionics don’t like radiation
190/700 km - spacewalk - EVA suits
communicative over starlink - beam of light - laser communication - not primary means of communication 40 science and research experiments val allen radiation belt
vitenam - medicine availablility and communication via internet - starlink -
south atlantic anamoloy at 1200 km
novel - pre breath protocol → first 45 hours of the flight, slowly reduce the cabin pressure change in pressure sickness
spacesuit - 100% oxygen for a fixed duration before depressurising dragon
![question] why does nitrogen cause more pressure problem, is that the reason for choosing 100% oxygen
14.1
32% oxygen at 8 psi by the end of the mission
adding nitrogen repressisation in dragon for repressization
making sure every component inside dragon is rated for operation in vacuum mobility aids inside the spacecraft when wearing the suits
emu - 4.5 a7 l - <4 psi
spacesuit pressure - close to 5 psi
extra dcs protection by having high suit pressure
dexterity, mobility of the spacesuit at 5 psi
copper coating - visor - ITO to retain heat - anti fog coating - impact resistance - only single layer visor - does not limit visibility (full range)
exntrance and exit using waist zipper - for eva suit
the spacesuit is soft when not pressurized and becomes pressuiresed become rigid
pyron felt on boots on spacesuit
MLI stacked up in spacesuit
redundant oxygen inlet for spacesuit and redundant
total EVA time 2 hours - jared and sara
