Two rovers on their way to Mars

Home
NASA wants to send their fifth rover to Mars in 2020. At the same time, the first vehicle of the European Space Agency (ESA) is scheduled to land on the Red Planet. We show the characteristics and differences between the two high-tech rovers

NASA – Mars 2020

Start: July/August 2020

Rocket: Atlas V-541

Mission: Finding out if there has ever been life on Mars. Taking soil samples and sealing them in containers that can later be collected and brought back to Earth.

Cost: 2.1 billion US dollar

maxon drives: Nine brushless DC motors (for handling the soil samples), EC 32 flat and EC 20 flat with planetary gearhead, everything specifically optimized for the Mars mission in cooperation with NASA/JPL

ESA – ExoMars

Start: July/August 2020

Rocket: Proton

Mission: Looking for former or current life. A drill takes soil samples from a depth of two meters. The rover analyzes the samples on-site with measuring instruments.

Cost: 1.8 billion dollar (incl. the preliminary mission of 2016)

maxon drives: More than 50 actuators, from the wheel drive to sample distribution to camera movement, with 17 different configurations of brushed or brushless DC motors (such as DCX 10, DCX 22 or EC 40) in combination with gearheads (such as GP 22 HD), brakes and encoders

 

Planet Mars

  • Mars is the fourth planet from the sun and is considered to be an earthlike planet.
  • Average temperature: –55°C
  • Diameter: 6.779 km
  • Orbital period: 687 days
  • Length of the day: 1d 0h 40m
  • Gravitation: 38 percent of the gravity on Earth
