During SpaceX's last launch in June, a faulty rig, called a strut, broke shortly after lift off, which caused one of the fuel tanks to burst, setting off a chain reaction that destroyed the rocket and its unmanned Dragon spacecraft.

Since then, SpaceX has made some major and exciting upgrades to its rockets.

The aerospace engineering and launch services company, founded and run by billionaire entrepreneur Elon Musk, will be flying its upgraded Falcon 9 for the first time this weekend. It will also be the first SpaceX launch since June.

And the upgrades certainly get Musk's esteemed seal of approval:

"I think it's a significantly improved rocket from the last one," Musk said during a Dec. 15 talk at the American Geophysical Union's Fall Meeting, according to SpaceNews.
