Opportunity stands 4.9 feet (1.5 meters) high, 7.5 feet (2.3 meters) wide, 5.2 feet (1.6 meters) long, and weighs 400 lbs. (180 kilograms). The rover is solar-powered. Opportunity’s on-board computer uses a 20 MHz RAD6000 CPU with 128 MB of DRAM, 3 MB of EEPROM, and 256 MB of flash memory.
How fast can rovers go?
The rover has a top speed on flat, hard ground of 4.2-centimeters per second, or 152 meters per hour. This is a little less than 0.1-miles per hour. For comparison, a 3 mile-per-hour walking pace is 134 centimeters per second, or 4,828 meters per hour.
How much do the rovers weigh?
It is car-sized, about 10 feet long (not including the arm), 9 feet wide, and 7 feet tall (about 3 meters long, 2.7 meters wide, and 2.2 meters tall). But at 2,260 pounds (1,025 kilograms), it weighs less than a compact car.

What were Rovers used for?
Rovers are typically created to land on another planet (other than Earth) via a lander-style spacecraft, tasked to collect information about the terrain, and to take crust samples such as dust, soil, rocks, and even liquids. They are essential tools in space exploration.
What did the Opportunity rover discover?
Opportunity discovered tiny cavities in the rock that were similar in shape and size to rock cavities on Earth that are left behind when certain minerals are dissolved and dispersed by groundwater. Credit: NASA/JPL-Caltech.
Why do rovers have six wheels?
This type of suspension is called rocker-bogie and it allows the rovers to overcome larger obstacles with better tilt stability. This setup allows the rovers to keep all of their six wheels on the ground at all times while staying stable. …
What are Rovers made of?
Like a car body, the rover’s aluminum shell is a strong outer layer that keeps the vehicle’s vital and sensitive electronics protected and temperature controlled. “NASA could not have made it to the surface of Mars without aluminum.”

Mars Exploration on Overdrive.
How many rovers sent to Mars?
There have been four rovers operated on the surface of Mars. The Viking probes, which were launched in the 1970s, were the first robots to land on Mars.
What robots are on Mars?
The spacecraft are using scientific tools to measure the temperature and the kinds of minerals on Mars. They are also taking pictures and searching for water. Two robots that move, called rovers, are on Mars’ surface. Their names are Spirit and Opportunity.
What wheels are on Mars rover?
Rover Wheels. The Mars Exploration Rover has six wheels, each with its own individual motor. The two front and two rear wheels also have individual steering motors (1 each). This steering capability allows the vehicle to turn in place, a full 360 degrees. The 4-wheel steering also allows the rover to swerve and curve, making arching turns.
