Keeping a good 45 degree Fahrenheit state can comfortably protect the battery and some sensitivity Key components such as electronic components are not damaged in extremely cold temperatures.

Before Ingenuity landed (originally only a few inches above the ground), Perseverance will charge the battery of the small helicopter to a 100% charge state. This is important because after landing, the “Ingenuity” must run its own heater on its own battery, and no longer need to get free electricity from the rover.

But there is another one on Mars Kind of free energy: that is the sun. The energy of the sun is relatively weak on Mars, only a little more than half of the sunny days on Earth. But this is enough for Ingenuity’s high-tech solar panels to charge the battery. Of course, this means that the detector must leave the mother ship after landing, in order to deploy the solar panels, and everything must be done as soon as possible after being separated.

If Ingenuity cannot keep the internal temperature at a “comfortable” 45 degrees Fahrenheit, it will consume too much precious energy from the battery. Conversely, when it hits the ground and wakes up automatically, it will set the thermostat to 5 degrees Fahrenheit or lower. Then, it will spend the first night on its own in a dormant attitude! The “Ingenuity” team is anxiously waiting for news from the helicopter. Has it survived the night? Are the solar panels working as scheduled? The team will check the temperature and battery charging performance in the next few days. If everything looks good, then go to the next step: untie the double rotor and test all the motors and sensors.
