SpaceX, the company backed by tech giant Elon Musk has successfully landed the rocket for the third time in a row, apparently it is the fourth time, on a droneship in the Atlantic Ocean. The company launched the 229-foot-tall Falcon 9 rocket at 5:40pm on Friday from Cape Canaveral Air Force Station in Florida, where the first stage of the rocket booster separated from it and came down to Earth.

The second stage of the rocket which was carrying a 3000kg commercial communication satellite THAICOM 8 owned by Thailand’s Thaicom has been put into a geostationary transfer orbit (GTO), 22,000 miles above the Earth. The satellite will spend rest of its life over there for 15 years providing internet and TV services for South Asia and Southeast Asia.

The first successful landing on the ship did on April 8, which just went high to the ISS 240miles above the Earth. The company started trying to land its rockets on land back in January 2015 but it was successful only in December 2015.

The main objective of these landings is to create to clean reusable rockets that would save millions of dollars as the company doesn’t have to build a new rocket from scratch. This will change the traditional design of rocket that was designed for a single use only, burning up or crashing into the ocean after liftoff.
