Bright Rocks on the Horizon: An Exciting Glimpse of Uncharted Territory” is a statement from NASA about the rover Perseverance’s upcoming traverse. The rover will climb up onto the Jezero Crater Rim after stopping in Neretva Vallis, a deep channel that may have once fed water and sediments into Jezero Crater. 

Jezero Crater is a 45 km-wide landing site for NASA’s Perseverance rover. It is the site of a suspected ancient lake and river delta. 

Perseverance is a 1-ton, six-wheeled Mars rover that is the size of a compact car. It can operate through dust storms that block sunlight required by solar-powered spacecraft. As of January 17, 2024, Perseverance has been active on Mars for 1,063 Earth days, or 2 years, 10 months and 30 days.

The first long-distance glimpse of this uncharted territory did not disappoint! Based on orbital satellite images, rock layers near the Jezero Crater Rim are thought to be among the oldest rocks that could be explored by a rover on Mars

Here’s some information about NASA’s Perseverance rover’s upcoming traverse:

• Traverse Perseverance’s traverse from “Séítah” to Jezero Delta is a mission to study the planet’s past climate and geology. 
• Science objectives Perseverance’s science objectives include:
  • Looking for habitability 
  • Seeking biosignatures 
  • Catching samples 
  • Preparing for humans 
• Astrobiology A key objective for Perseverance’s mission is astrobiology, which includes searching for signs of ancient microbial life. 
• Mission Perseverance’s mission is to collect and cache Martian rock and regolith. It also aims to identify and collect rock cores and other samples of Mars material. Perseverance is a six-wheeled, one-ton Mars rover that launched on July 30, 2020. 

The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust

As of January 29, 2024, Perseverance has been active on Mars for 1,075 Earth days, or 2 years, 11 months and 11 days since its landing on February 18, 2021. 

NASA estimates that the sample retrieval lander will land by 2028 at the earliest and that the collected samples won’t arrive on Earth until at least 2033

Yes, orbital satellite images indicate that the rock layers near the Jezero Crater Rim on Mars are among the oldest rocks that could be explored by a rover. 

The Jezero Crater region is geologically rich, with landforms dating back 3.6 billion years. The Perseverance rover, which launched on July 30, 2020, has been studying the crater’s environs since February 18, 2021. The rover has found 3.5-billion-year-old Martian rocks and soil scattered on the crater floor.

Scientists are investigating the region to see if they can find evidence of ancient life recorded in the rocks

Jezero Crater is a good place to look for signs of ancient life because of the delta it contains. A delta is a clear sign that a large lake once filled the crater. Lakes are potentially habitable environments, and delta rocks are a great place to store signs of ancient life as fossils

Scientists believe that ancient river flow into Jezero created environments that are likely friendly to life. The crater is now a dry, wind-eroded depression, but images taken by the rover show that it was once a quiet lake fed by a small river about 3.7 billion years ago. The images also show evidence that the crater endured flash floods

Jezero Crater is a crater on Mars that’s about 28 miles in diameter and located in the Syrtis Major quadrangle. The crater is about 750 miles across and was formed by an ancient meteorite impact

The crater’s floor is a mosaic of sedimentary rocks, including clays and carbonates, which are indicators of past aqueous environments. The crater also contains a fan-delta deposit that’s rich in clays

In addition to rocks and soil, the Perseverance rover has found evidence of ancient lake sediments, organic matter, and a diverse set of organic molecules

NASA chose Jezero Crater as the landing site for the Perseverance rover because of its many features that indicate an ancient lake:

• Delta: A channel in the northwest corner of the crater leads into a fan-shaped plateau, which is clear evidence of a river depositing sediment into the lake. 
• River delta: The crater has a prominent and ancient river delta that spills into it. 
• River system: On Earth, large river systems build up enormous deposits of sediments. 
• Geologically rich terrain: The landing site has geologically rich terrain, with landforms that could potentially answer important questions in planetary evolution and astrobiology

On Earth, scientists have found such clays in the Mississippi river delta, where microbial life has been found embedded in the rock itself. This makes Jezero Crater a great place to fulfill the Mars 2020 mission’s science goal of studying a potentially habitable environment that may still preserve signs of past life
