The rover will be equipped with state-of-the-art technology designed to help it navigate through rough terrain, collect samples, and conduct experiments.
Goals of the Mission
One of the primary goals of this mission is to search for signs of ancient life on Mars. Scientists believe that if there was ever life on Mars, it would have existed billions of years ago when conditions were more favorable for life forms to develop. By studying rock formations and soil samples collected by the rover, scientists hope to find evidence that suggests past microbial activity.
Another important goal is to study Martian geology in greater detail than previous missions have allowed us to do so far. The rover will collect data using a variety of instruments designed specifically for geological research such as Mastcam-Z (a camera system), PIXL (an X-ray fluorescence spectrometer) among others.
What Makes This Rover Special?
the Mars 2020 Rover has been designed based on its predecessor Curiosity’s success but improved capabilities are added including new technologies like SuperCam-RMI which can rapidly identify minerals and organic compounds; MOXIE which produces oxygen from carbon dioxide atmosphere; etc. It has also been equipped with advanced technology such as an ultraviolet laser spectrometer that can detect signs of organic matter in Martian rocks and a drill that can collect core samples from rocks up to 2 inches in diameter. This will help scientists study the composition of Martian soil more thoroughly than ever before.
The Rover’s Landing Site
After years of research, NASA has selected Jezero Crater as the landing site for the Mars 2020 Rover. This location is believed to be an excellent place to search for ancient signs of life because it was once home to a lake that existed billions of years ago. The crater also contains two large deltas where sediment deposits may have preserved signs of microbial life.
Why the Search for Ancient Life on Mars Matters
The search for ancient life on Mars has been a topic of great interest among scientists and space enthusiasts alike. But why does it matter? In this section, we will explore the significance of finding evidence of past microbial activity on the Red Planet.
Understanding Our Origins
One of the biggest reasons why searching for signs of ancient life on Mars matters is that it could help us understand our origins as a species. If we can find evidence that suggests that life existed elsewhere in our solar system, it would mean that life may not be as rare as previously thought. This would open up new avenues for research and exploration, especially when looking beyond our own planet.
The Possibility of Life Beyond Earth
Another reason why finding signs of ancient life on Mars is so important is that it could increase the likelihood of discovering other forms of extraterrestrial life in our galaxy and beyond. If microbes once thrived on Mars, then there's a chance they could have also existed elsewhere in our solar system like Europa or Enceladus which are considered to be some viable places to look at next.
Advancing Technology and Space Exploration
In addition to changing how we view ourselves and other potential forms of extraterrestrial life, discovering evidence of past microbial activity on Mars could also lead to advancements in technology and space exploration itself. It can provide important data about how living organisms adapt to extreme environments such as radiation exposure or desiccation which may have practical implications here on Earth. Moreover, successful missions like this one inspire young people who may later become scientists or engineers themselves leading towards technological advancement.
Understanding Climate Change
Studying Martian geology helps us understand climate change better because its atmosphere was once similar to ours before being stripped away by solar winds; hence studying its history can give us clues about what might happen if/when Earth's climate changes drastically such as what happened during the late Permian extinction.
Discoveries from the Previous Mars Rovers: Building Blocks for the Mars 2020 Mission
the Mars 2020 Rover mission builds on the successes of previous missions such as Spirit, Opportunity and Curiosity.
