NASAの火星探査車キュリオシティが、火星表面での最近のサンプル採取の試み中に予期せぬ課題に直面した。
4月29日に行われた作業の後、探査車のドリルが幅約1.5フィート（約45センチ）、重さ約30ポンド（約13.6キロ）の岩盤に引っかかった状態となった。カメラがその様子を捉えており、ドリルビットに岩が付着しているのが確認された。キュリオシティの14年にわたる火星探査において、これまでの掘削作業でこのような事象が発生したことは一度もなかった。

Scientists have found that localized dust storms on Mars can drive water vapor into the upper atmosphere, where it breaks apart and escapes into space. The discovery, based on observations from multiple Mars orbiters, challenges prior assumptions about when and how the planet loses water. Researchers link the effect to an intense regional storm during the Northern Hemisphere summer.
