- Perseverance is searching for signs of ancient life. While the surface of Mars is a frozen desert today, scientists have learned from previous NASA missions that the Red Planet once hosted running water and warmer environments at the surface that could have supported microbial life.
- The rover is landing in a place with a high potential for finding these signs of past microbial life. Terrain that is interesting to scientists can be challenging to land on.
- Perseverance is also collecting important data about Mars’ geology and climate. Context is everything. Mars orbiters have been collecting images and data from Jezero Crater from about 200 miles (322 kilometers) above, but finding signs of ancient life on the surface requires much closer inspection.
- Perseverance is the first leg of a round trip to Mars. The verification of ancient life on Mars carries an enormous burden of proof. Perseverance is the first rover to bring a sample caching system to Mars in order to package promising samples for return to Earth by a future mission.
Aug 1, 2020 · The spacecraft departed Earth at a speed of about 24,600 mph (about 39,600 kph). The trip to Mars will take about seven months and about 300 million miles (480 million kilometers).
Apr 12, 2022 · In a new video, a NASA JPL rover driver explained that Perseverance is “ thinking while driving ” and can hit a top speed of 0.1 miles per hour. This speed allows the rover to cover 300 yards per day while staying safe on the tough Mars terrain.

One of Perseverance’s first activities in surface mode is to take a pair of pictures with the engineering cameras – known as the Hazard Cameras, or Hazcams – on the front and rear of the rover. Hazcams have clear covers over their lenses to protect them from dust that gets kicked up during landing. The first two images – front and rear Hazcam image...
Perseverance’s first Martian day on the surface of the Red Planet is known as Sol 0. A sol is a Martian day, which is 24 hours, 39 minutes, 35.244 seconds. (Perseverance team members tend to refer to sols rather than Earth days during operations since the rover will be working during the Martian day and “sleeping” during the Martian night.) The pri...
After mission controllers have determined that rover systems are functioning as desired, Perseverance will find a flat area to serve as a helipad for the Ingenuity Mars Helicopter technology demonstration. In the first months after landing, if all goes well, the rover will deploy Ingenuity in the center of this area and drive a safe distance (about...
At the end of these experimental helicopter flights, Perseverance will begin its surface operations phase, when the team will carry out its ambitious science mission: searching for signs of ancient microbial life, characterizing the climate and geology of Mars, and collecting carefully selected and documented samples for future return to Earth. Fin...
Why Mars? At an average distance of 140 million miles, Mars is one of Earth's closest habitable neighbors. Mars is about half again as far from the Sun as Earth is, so it still has decent sunlight. It is a little cold, but we can warm it up.
