GGB goes to Mars on the Perseverance rover
GGB lands on Mars again.
In February 2021, GGB bushings landed on Mars aboard the Mars Rover, Perseverance.
GGB bearings support the Perseverance rover in examining Martian rock.
Mission Mars 2020 has the Perseverance seeking signs of ancient life, while also collecting samples or rock and soil for possible return to Earth. GGB worked with NASA's Jet Propulsion Laboratory to find the best tribological solution for use in the sampling and caching System. Ultimately, GGB and JPL decided on GGB's DP4-B bearings to be used in multiple places within the sampling and caching System on the rover, serving as the primary suspension components in the robotic drill arm for collecting Martian rock. DP4-B delivers the same dry running capability as DP4® coupled with the bronze substrate to improve corrosion resistance allowing the Perseverance's drill to function in the extreme Martian environment where temperatures range from -328°F (-200°C) to +536°F (+280°C).
