3. Introduction
A mars rover is a motor vehicle that travels across the surface of
the planet mars upon arrival.
Landed spacecraft can make detailed observations of a planets
surfaces.
To obtain coverage over a wider area,spacecraft can carry robots
that are able to rove over the surfaces.
Crewed missions or robotics rovers provide not only mobility but
also the capability to do complex tasks and make intelligent and
selective observations.

4. Types of rovers
 sojourner
 spirit and opportunity
 curiosity
 perseverance

5. Mission
• looking for habitability
• seeking biosignatures
• caching samples
• preparing for humans

7. Perseverance(rover)
• The mars 2020/perseverance rover is designed to better
understand the geology of mars and seek signs of ancient life.
• The mission will collect and store a part of rock and soil samples
that could be returned to earth in the future.
• It will also test new technology to benifit future robotic and human
exploration of mars.

8. Mission Timeline
• Launch july 30,2020 from cape canaveral air force station,florida.
• Land on mars on february 18,2021 at the site of an ancient river
delta in a lake that once filled jezero Crater.
• Spend at least one mars year(two earth years) exploring the landing
site region.

9. Mars 2020 mission contributions
to nasa mars exploration program
science goal
 determine whether life ever existed on mars.
 characterize the climate of mars.
 characterize the geology of mars.
 prepare for human exploration

11. Mars helicopter

12. Mars ingenuity helicopter:
 The mars helicopter,ingenuity is a technology demonstration to test
powered,controlled flight on another world for the first time.
 It hitched a ride to mars on the perseverance rover.
 The helicopter completed its technology demonstration after three
successful flights.
 A technology demonstration to test the first powered flight on
mars .The helicopter rode to mars attached to the belly of the
perseverance rover.

13. Conclusion
 perseverance early observations are already revealing that jezero‘s
geologic history is richer than previously imagined,with dramatic
shifts in envinormental conditions.
 perseverance has finally collected samples from the site of an
ancient river delta,which is full of rock layers that serve as a
geological record of the martian past.
 some of the rocks include the highest concentration of organic
matter found by the rover to date,according to NASA scientists.
