The curiosity rover is bigger needs more power.
Curiosity rover solar panels.
Curiosity carries a radioisotope power system that generates electricity from the heat of plutonium s radioactive decay.
Named curiosity it was the largest rover to be placed on the surface of mars.
Without power it cannot move use its science instruments or communicate with earth.
This power source gives the mission an operating.
Mars exploration rovers spirit and opportunity exploring the planet mars facts information videos and pictures.
One consequence is that the mars exploration rovers couldn t work for more that half of the time.
They believe the dust covered the rover s solar power.
On august 6 2012 the most recent rover landed on mars.
The rovers by name curiosity.

Of course the insight lander currently operating on the red planet bears solar panels.
The electrical output from the mmrtg charges two rechargeable lithium ion batteries.
The power source generates 9 mj 2 5 kwh of electrical energy each day much more than the solar panels of the now retired mars exploration rovers which generated about 2 1 mj 0 58 kwh each day.
But these plutonium units are a respected power source for spacecraft nasa s curiosity rover.
