Global reentry between the atria and ventricles may involve accessory conduction pathways ("bypass ...
WebEngineers estimate the spacecraft could be exposed to temperatures as high as about 2,370 degrees Fahrenheit (about 1,300 degrees Celsius) from the friction generated as it descends through the Martian atmosphere. The job of the heat shield is to carry most of this heat away from the Perseverance rover. The concept of the ablative heat shield was described as early as 1920 by Robert Goddard: "In the case of meteors, which enter the atmosphere with speeds as high as 30 miles (48 km) per second, the interior of the meteors remains cold, and the erosion is due, to a large extent, to chipping or cracking of the suddenly heated surface. For this reason, if the outer surface of the apparatus were to c…
