SpaceX successfully launched the SES-9 satellite into orbit, failing to land missiles on barges

In the early morning of March 5, Vietnam, SpaceX launched Falcon 9 rocket into space and successfully put SES-9 satellite into orbit, after 4 previous delays. However, as expected of the company, the missile was unable to land safely on the floating platform located off the Atlantic Ocean. On his personal page, CEO Elon Musk said the landing process was really difficult. This is SpaceX's fourth attempt to land Falcon 9 on the autonomous ship at sea. All previous landings had failed, although the third attempt ended in regret.

Very keen to land missiles on the sea, but the Space Exploration Technology Corporation also did not expect a successful landing, before starting this mission. In their mission, they have to use rockets to bring a very heavy satellite into high orbit. That required a lot of fuel, so there was not much fuel left for the return to Earth on the journey of Falcon 9.

SES-9 satellite separated and prepared to enter orbit.

So far, SpaceX has only once successfully landed the Falcon 9 missile to the ground, creating a huge buzz last December. Land landing is much easier than landing on the sea; because of its stability compared to a small ship floating in the ocean. Despite the difficulty, SpaceX will continue to try to perfect sea landing techniques , since not all missions can land missiles on the ground. Landing on the sea requires less fuel, so it is suitable for missions that require missiles to move at great speeds.

Landing failed, but SpaceX still achieved the main goal of the day, which is to bring telecommunications satellites into space for their customers - SES company. SES-9 satellites were separated at a high altitude and would use their own propulsion to enter the expected orbit. Finally, the SES-9 will operate at a distance of more than 35,400 kilometers above the equator, providing communication services to countries in Northeast Asia, South Asia and Indonesia.

SpaceX was assigned to carry supplies to the International Space Station (ISS) in a few weeks for NASA. It is still unclear whether they plan to land their missiles on the ground or at sea, but Elon Musk says the mission is a "good opportunity" for landing efforts.
