Perseverance Rover Tops 26.2 Miles on Mars, Completing Marathon After 5 Years

3 articles · Updated · Space.com · Jun 18

Summary

  • NASA said Perseverance has now traveled more than 26.2 miles, or 42.2 kilometers, across Mars since landing in February 2021.
  • The milestone makes Perseverance only the second Mars rover to complete a marathon-distance trek; Opportunity also did it, but took more than 11 years.
  • Perseverance covered the distance while exploring the Martian surface and carrying out scientific investigations, not as a dedicated speed run.
  • The benchmark also underscores the scale of future human Mars challenges, with surface travel complicated by temperatures as low as minus 225 F, a 95% carbon-dioxide atmosphere and bulky spacesuits.
