On June 28 off the coast of Hawaii, NASA did an experiment on a saucer-shaped device for landing and exploring the Mars.
However, its parachute didn't open and the device plunged into the sea.

The experiment was a series of technical development plan in order to send a large probe vehicle and emigrants to the Mars.
The device called LDSD is being developed to help reduce speeds so that landing on the Mars is safer.
The LDSD was lifted off by a balloon from the Navy’s Pacific Missile Range Facility in Kauai.
When it reached an altitude of about 37 kilometers, it additionally went up at a speed four times as fast as the sound with a rocket motor.
After that, they succeeded in slowing down with an air cushion.
However, the 30-meter-diameter parachute didn't work.

米航空宇宙局(NASA)は28日、ハワイ沖で円盤のような形をした火星探査向け着陸装置の飛行実験を行ったが、パラシュートが正常に開かず海に落下した。

実験は、大型探査機や移住者を火星に将来送り込むための技術開発計画の一環。火星への着陸を安全に行うために開発中の減速装置「LDSD」は、同州カウアイ島の米海軍ミサイル施設から気球で約37キロ上空に上がった後、ロケット噴射で音速の約4倍でさらに上昇。その後、装置に付けられたエアクッションを膨らませて減速したものの、直径約30メートルのパラシュートは適切に機能しなかった。
