A planned controlled landing – SpaceX Falcon 9 rocket did it again.

Isn’t it the right time to witness the rocket science aka aerospace engineering?

SpaceX Falcon 9 rocket was successfully launched today (May 1st, 2017) to deliver a payload.

What is so fascinating about this particular launch?

SpaceX Falcon 9 was descended back to the ground without being destroyed. This means it can be reused for another mission in the near future. In the past, it was not possible to reuse the rocket and this is the second time that SpaceX did successfully.

What needs to be improved?

Falcon 9 seems to work well on a very low earth orbit (LEO) (99 to 1200 miles above the ground) from observing the launch data. At lower earth orbit, an object (satellite) will experience a very rapid orbital decay and attitude loss. That being said, it will take roughly 88 minutes to complete one cycle at about 99 miles above the ground.
