NASA's Perseverance Mars rover reaches the top of Jezero Crater's rim, called Lookout Hill. It took approximately 3.5-months, ascending 1,640 vertical feet, and climbing 20% grades to achieve this feat. Perseverance is currently working on the Northern Rim campaign, which marks its transition from rocks that partially filled Jezero Crater when it was formed by a massive impact about 3.9 billion years ago to rocks from deep down inside Mars that were thrown upward to form the crater rim after impact.
