Le rover Curiosity de la NASA a fait face à un défi inattendu lors d'une récente tentative de prélèvement à la surface de Mars.
La foreuse du rover est restée bloquée sur une dalle rocheuse d'environ 45 centimètres de large pesant près de 13,6 kilogrammes après une tentative le 29 avril. Les caméras ont capturé l'incident, montrant la roche fixée au foret, un phénomène jamais observé au cours des 14 années de présence du rover sur Mars malgré les précédentes activités de forage.

NASA's Artemis II crew became the first humans in over 50 years to loop around the moon's far side on April 6, traveling farther from Earth than any before them. The astronauts captured unprecedented views, including close-ups of craters and a unique solar eclipse. They are now heading back for a splashdown off California on April 10.
NASA engineers resolved an unexpected problem with the Curiosity rover when its drill became stuck on a rock on Mars. The incident marked the first time the agency faced this specific issue. It took nearly a week to free the tool.

NASA's Perseverance rover sent back a new selfie from Mars this week after venturing west of Jezero Crater.
NASA has awarded nearly $720 million in contracts for two one-ton South Pole rovers and their Blue Origin lander delivery, signaling a narrower focus than earlier full-scale base concepts.

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.
