 Perseverance, nicknamed Percy, was once thought of as a clone of MSL Curiosity, which landed in Gale crater in 2012.  Some of the systems are the same and some have been updated with current technology.  The 2020 rover is over 150 kg heavier than the MSL rover, weighing in at 1,025 kg.  Perseverance will utilize the same landing system as Curiosity, the skycrane, which is enhanced with updated technology such as terrain relative navigation.  This system will help Perseverance avoid landing in a dangerous area.  Another new technology is the system called range trigger, which tells the parachute when to open in order for the rover to land in the desired landing spot.  This technology saves time, as previous rovers had to land in a flat area and later drive to the more interesting targets.  Perseverance has updated titanium wheels which include cleats and spokes as scientists discovered that Curiosity’s wheels were being damaged by the sharp rocks. The wheels for Perseverance were redesigned to withstand damage from the sharp rocks.

-<div align="justify" style="text-align:justify;padding-right:5px;">'''[[Terraforming Mars]]''' is a process by which scientists hope to convert Mars into an Earth-like planet, providing an atmosphere within tolerable limits for human survival. NASA and other science organizations have been discussing a process called terraforming for a very long time. Terraform means to make like Earth. Many proposals have been submitted on the best way to make Mars like Earth. The timelines proposed have varied from 100 years to 100,000 years.  Logic dictates finding a balance between moving too fast and too slow. If we terrraform too fast, we may end up with a runaway greenhouse effect similar to what we see on Venus. If we move too slowly, we run the risk of other complications, such as the natural rhythms of the Red Planet changing during the process which could interfere and complicate any progress we may be making. Terraforming Mars is of utmost importance in order to learn to live on other worlds. Humanity must have the ability to be a multi-planet species in order to preserve Homo sapiens for millions or billions of years. </div>
