The engineering to pull that off is WAY beyond anything I ever learned in engineering school. Congratulations, Space X. Why no core-return, though? Inquiring minds..........

Not enough fuel left after mission profile to do reentry and landing burns.
Between the time boosters had to separate and MECO the center core gained more than twice as much altitude (54 -> 112 miles). I'm sure the taxpayers more than adequately covered the cost of expended booster to get their satellite to proper orbit.

You'll also notice that the center booster has no landing legs or grid fins; all left off to save weight and enable it, along with the remaining fuel, to get to the desired orbit.

Either way, we all paid for it! There is a small group of hobbyist astronomers that track satellites in-orbit and frequently publish/update the six constants that define an orbit. AKA: Keplerian elements. Their software is very advanced … even NASA and USAF uses it.
