Flew for the 17th time at Mars on Sunday, December 5. The helicopter completed the scheduled 614-foot (187-meter) journey to the northeast, radio communication connection to Ingenuity with Perseverance Perseverance Mars rover was cut off during the final descent stage in the course. About 15 minutes later, Perseverance received several packets of additional telemetry from Ingenuity, indicating that the batteries and electronics of the flight were in good condition.

The telemetry available during and following the flight indicates that the mission was successful. The link failure resulted from a complex radio configuration that required Perseverance and Ingenuity on the landing. Before we can plan the next mission, it is necessary to transfer the data missing that was lost during Flight 17 from the helicopter to the Rover, then back to Earth to verify the vehicle’s condition.

From our information, the spacecraft did not perform well throughout its 117-second flight of 33 meters (10 meters) higher than the surface of Mars. The telemetry disappeared in the last portion of our flight, approximately 10-feet (3 meters) away from the surface. The way radio links behave concerning the nearby surfaces can help understand why the loss of link happened at the time of landing.

Radio Links

The strength of radio signals is largely dependent on the clearness of the path (also known as line-of-sight (LOS) is between the receiver and transmitter antennas. This path may be blocked due to the terrain when the helicopter is positioned in an area of depression or on the opposite edge of a hill or even by the structure of the Rover when the helicopter happens to be located on the side of the Rover’s ports (left) or the stern (back) or back. In this particular instance, Ingenuity was confronted with the task of communicating between the structure of the Rover and the Multi-Mission Radioisotope Thermal Generator (MMRTG) (see the red vector of LOS in the illustration of the Rover).

Ingenuity was also required to fly to a location for landing that was a 13-foot (4 meters) hill known as “Bras” (named after a commune located in France). The hill was located in it was the LOS of the antennas. With a maximum altitude of 33 feet (10 meters), Bras presented little interference in our connection to the radio for most of our flight. However, once Ingenuity lowered the line of sight between the helicopter and Rover, antennas started to be blocked or shadowed by Bras.

When we initially set out to plan Flight 17, we believed that the Rover was to be placed in an exact location and pointed in a specific direction. But, the plans of Perseverance change from each day to increase the total science output. When Flight 17 was ready for flight, Perseverance had driven to an alternate location and had stopped along a difficult route to ensure radio communication (the blue LOS in Figure 2.).

Since the beginning of the helicopter’s operational demonstration, we’ve accepted the possibility of radio loss upon landing due to the nature of our more difficult flights. Ingenuity was developed to deal with the situation by automatically powering down following a flight and awaiting instructions for the next sol that we anticipate to be the case after Flight 17. These issues are among the lessons we have learned by exploring aerial activities in the complexities of everyday Rover operations.

Flight Evaluation

We are convinced that the flight was successful as everything we can see from the helicopter available suggests anything else. Telemetry is nominal, leading to the point that the radio link stopped.

The most telling part is the data packets received 15 minutes later than the time landing would have happened. The packets contained an analysis of the battery’s voltage, showing +76 millivolts equivalent to a +1.2 percentage increase in the state of charge over 15 minutes. The battery was recharged through the solar array of the helicopter. This high-quality battery charge is only feasible when a vehicle is upright, and its solar array is pointed toward the Martian sky.

Next Steps

The first chance to download the missing information of Flight 17 will be no later than Wednesday. Following that, the group will complete its health evaluation. The flight was planned to take us back towards the “Octavia E. Butler” landing site “Octavia E. Butler” landing area by flying halfway over “South Seiitah.” We plan on Flight 18 to occur in the coming weeks. This will bring Ingenuity further to a distance of 200m northeast, which is just shy of the northern end of S. Selah.

As Ingenuity expands and makes it fly higher in the future, we anticipate once again experiencing the loss of radio links on landing, just like what happened on Sunday. We will do everything we can to avoid these issues (when possible). However, it is a fact that temporary loss of radio links is a normal element of helicopter operations on The Red Planet.
