Technical problems with Ingenuity

The inclination sensor of Ingenuity, from NASA’s Mars 2020 mission, stopped working. But there is already a solution to this problem.

More information about Ingenuity and the first flight’s video are in the following link.

NASA’s Mars helicopter Ingenuity has suffered a sensor failure, according to Håvard Grip, the chief helicopter pilot on the project. In a recent blog post on the NASA Science page, he described some of the challenges the tiny robot is experiencing in the harsh environment and also noted that a sensor failure is going to require a computer patch.

A patch is a software update to correct errors and improve the program’s performance.

Ingenuity has been on Mars since February 2021, along with the Perseverance rover. Since that time, it has flown 28 times, significantly more than was originally planned. Its initial assignment was to determine if a helicopter could be flown on Mars. Ingenuity has shown that it can—and far more. Its current missions generally entail surveying the landscape around Perseverance, helping to plot its course.

But the harsh environment on Mars has posed challenges for the tiny helicopter and the crew working to keep it flying. First of all, according to Grip, since the helicopter was not expected to last as long as it did, measures were not taken to ensure it could get enough power from the sun during the short Martian winter days. Thus, it has to shut down at night. That leaves it exposed to temperatures as low as -80 degrees Celsius, which could lead to damage of its electronics. And the constant shift in temperature extremes could lead to damage as well. The helicopter, along with every other vehicle sent to Mars, also has to contend with constant dust, which is even more prevalent in the winter.

Ingenuity has held up remarkably well despite these conditions, Grip notes. However, a sensor called the inclinometer has stopped working. While not needed for flight, it is needed to orient the helicopter prior to lifting off. Grip notes that the team that designed Ingenuity took this possibility into consideration and developed a patch to solve the problem before the helicopter ever got to Mars. The patch is meant to use information from other sensors and essentially fool the helicopter into thinking it is getting the data from the inclinometer. He notes that the patch will be sent and installed soon, and he expects Ingenuity to resume flight shortly thereafter.
