Jezero Crater

Definition

Jezero Crater is an ancient impact crater located on Mars that is about 45 kilometers wide and is thought to have once hosted a lake, making it a prime target for astrobiological studies. Its unique geology and potential to contain preserved signs of past life have led to its selection as the landing site for NASA's Perseverance rover, which is currently exploring the crater's surface and collecting samples for future return to Earth.

5 Must Know Facts For Your Next Test

1. Jezero Crater was chosen as the landing site for Perseverance due to its past presence of water and sedimentary rocks, which may harbor clues about ancient microbial life.
2. The crater features a delta formation that suggests the area was once filled with a lake, providing ideal conditions for the development of life.
3. Perseverance landed in Jezero Crater on February 18, 2021, and has been conducting experiments to analyze the crater's rock and soil composition.
4. The mission aims not only to search for signs of past life but also to test technologies that could help future human exploration of Mars.
5. Jezero Crater’s geology includes ancient river channels and minerals that are of great interest to scientists studying Mars' climate history and habitability.

Review Questions
