"SpaceX just successfully landed the first stage of its Falcon 9 rocket on a drone ship in the Atlantic Ocean. It was the third time in a row the company has landed a rocket booster at sea, and the fourth time overall.
The landing occurred a few minutes before the second stage of the Falcon 9 delivered the THAICOM-8 satellite to space, where it will make its way to geostationary transfer orbit (GTO). GTO is a high-elliptical orbit that is popular for satellites, sitting more than 20,000 miles above the Earth. The 3,100-kilogram satellite will spend 15 years there, helping to improve television and data data signals across Southeast Asia.
After landing, SpaceX CEO Elon Musk said that there would be 'some risk of tipping' as the rocket was brought back to port."
