Artemis II daily logbook 5: Preparing for a historic lunar flyby and testing spacesuits

On flight day 5, Orion entered the lunar sphere of influence ahead of the lunar flyby.

The crew conducted several tests of the Orion Crew Survival System (OCSS) spacesuit. They tested suited seat entry, suit pressurization, mobility, and ability to eat and drink. (Credits: Canadian Space Agency, NASA)

Every day aboard Orion starts like your day at home:

• Eat breakfast 
• Brush teeth 
• Freshen up

The astronauts also do a 30-minute workout nearly every day using a suitcase-sized flywheel. 

The flywheel can be used for activities like cardio and strength training by generating up to 180 kg of resistance.

The crew tested their Orion Crew Survival Systems, the orange suits that protect them during launch, reentry in the atmosphere and splashdown. 

They can also provide a breathable atmosphere for up to six days in case of emergency. 

The astronauts put on and pressurized their suits, simulating both an emergency situation and regular suit-up procedures. 

They checked for leaks, assessed mobility and their ability to eat and drink. 

Orion entered the lunar sphere of influence ahead of the flyby of the Moon. 

It is the point at which the Moon’s gravity is pulling harder on the spacecraft than Earth is.

Canadian Space Agency astronaut Col. Jeremy Hansen was honoured with the gold astronaut pin to commemorate his first spaceflight. 

This pin is awarded to astronauts once they’ve flown, replacing the silver pin they receive after basic training. 

Congratulations, Jeremy! We’re proud of you... to the Moon and back!
