Asteroid Box Construction (sry i have no pics)
Each of the four sides of the box were constructed in low earth orbit. Each side was made up of 4 smaller pieces, assembled in Leo.
After a side was done, it was tugged, by another rocket (that docked of course) to the asteroid.
This was repeated for each side of the box.
The sides were then docked together to trap the asteroid.
The entire mission took roughly a day to complete.
