Space milestones are only going to keep on coming, with the first ever commercial space walk mission. 

Billionaire Jared Isaacman and engineer Sarah Gillis have become the first civilians to walk in space.  

The Space X mission also put the total number of people currently in space to 19, tying the record set in 2021. 

Auckland University's Spacecraft Missions Director Chris Jackson told Ryan Bridge the number's only going to increase with SpaceX and NASA's future plans. 

He says they want to populate the Moon, which will put a lot more people in space across a lot of different places.
