NASA's Mars rover Perseverance has completed a daring climb to the edge of Jezero Crater, overcoming steep slopes and rugged terrain to reach a new scientific frontier. The rover's fifth mission, exploring the North Rim, promises groundbreaking understanding of Mars' geological history, including rocks that may date back to the early days of the solar system. This mission is not only related to Mars, but also a step towards human exploration of the universe.

NASA's Perseverance rover has reached the top of the rim of Jezero Crater, which the science team calls "Lookout Mountain." After an arduous, months-long climb, the rover is now heading toward its first scientific destination in a new region that is unlike any it has explored before.

In three and a half months, Perseverance climbed 1,640 vertical feet (500 meters) along a steep mountain slope with a gradient of up to 20%. Along the way, it stopped for scientific observations. On December 12, during the American Geophysical Union's annual meeting in Washington, D.C., the science team shared details about the climb, their recent discoveries, and exciting plans for the rover's next phase of exploration.

"While climbing the rim of Jezero Crater, our rover pilots excelled in handling some of the harshest terrain encountered after landing," said Steven Lee, deputy manager of Perseverance at NASA's Jet Propulsion Laboratory in Southern California. "They found innovative ways to overcome these challenges - even trying to drive backwards. That perseverance is the starting point for everything the science team will do in the coming science activities."

Since landing on Jezero in February 2021, "Perseverance" has completed four scientific activities: the bottom of the crater, the "Front of the Sector", the "Upper Sector" and the "Ring Unit". The science team calls Perseverance's fifth campaign "Northern Rim" because its route covers the northern part of the southwest segment of Jezero Rim. During the first year of Operation North Rim, the rover is expected to visit up to four points of geological interest, collect several samples, and travel approximately 4 miles (6.4 kilometers).

Ken Farley, Perseverance project scientist at the California Institute of Technology in Pasadena, said: "As Perseverance enters a new geological realm, the North Rim activity brings us new scientific wealth. It marks our departure from the partially filled Jezero meteorite formed by a giant impact about 3.9 billion years ago. "These rocks represent fragments of early Martian crust and are among the oldest rocks found in the solar system. Studying them can help us understand what Mars - and our own planet - originally looked like," Farley added.

After leaving Lookout Mountain, Perseverance headed toward a scientifically significant rock outcrop about 1,500 feet (450 meters) on the other side of the crater, which the science team dubbed 'Witch Hazel Mountain.'

"This event starts off with a bang because Witch Hazel Mountain represents more than 330 feet of layered outcrops, each of which is like a page in the Martian history book. As we descend, we will travel back in time to investigate the ancient Martian environment recorded at the crater rim," said Candace Bedford, Perseverance scientist at Purdue University in West Lefayette, Indiana. "Then, after a steep descent, we left the crater rim for the first time and headed towards 'Lac de Charmes' (Lake Charmes) about 2 miles south."

Chaim Lake is of interest to the science team because it lies on a plain beyond the rim and is unlikely to have been significantly affected by the formation of Jezero Crater.

After leaving Charme Lake, the rover will travel about a mile (1.6 kilometers) back to the edge to investigate a stunning outcrop of giant gravel. The debris may represent ancient bedrock that was shattered during the Isidis impact, a planet-changing event that likely penetrated deep into the Martian crust and created an impact basin about 745 miles (1,200 kilometers) wide, 3.9 billion years ago.

Part of NASA's 2020 Mars mission, the Perseverance rover is a groundbreaking exploration vehicle designed to uncover the secrets of Mars and pave the way for future human exploration. A key focus of its mission is astrobiology - the search for signs of ancient microbial life by collecting and preserving samples of Martian rock and debris. The samples will be returned to Earth through the Mars Sample Return Program, a collaboration between NASA and the European Space Agency (ESA).

In addition to its astrobiological goals, Perseverance studies the geology and past climate of Mars, providing valuable data for future human missions to the Red Planet. The work is consistent with NASA's broader Moon to Mars initiative, which includes the Artemis missions designed to advance human exploration. Built and managed by NASA's Jet Propulsion Laboratory (JPL), Perseverance is an important step in humanity's journey to explore and understand the universe.
