Use the lines in the background to determine the height of the breakable blocks.

It is also possible to do this from the top right door's runway. Although there is a larger runway available above, minimizing the speed is important, so the runway is only slightly longer than the plateau, but the Space Jump is significantly more precise. With at least a one-tap short charge, jump off the ledge and descend as much as possible while keeping space jump active, by using well timed, short hops. Once approaching the wall, jump again to continue through all of the bomb blocks. If HiJump is available, it is much easier to use the blue space jump strat from the ground than from above.
