今日のテキスト OCEAN LANDING ATTEMPT FAILS

A SpaceX rocket has exploded after a failed vertical landing attempt on a floating platform in the Pacific.
The U.S. space venture company launched its Falcon 9 rocket from California and successfully delivered a satellite into space on Sunday. The first stage of the rocket descended vertically and landed on the designated spot on the platform, but toppled over after one of its four supporting legs malfunctioned.
SpaceX aims to reduce launch costs by developing technology to reuse the first stage of rockets rather than having them fall into the ocean.
The company successfully landed a rocket vertically on land in December, though its previous attempts on a floating platform have also failed.
