The 52nd flight of NASA’s Ingenuity Mars Helicopter is now in the official mission logbook as a success. The flight took place back on April 26, but mission controllers at NASA’s Jet Propulsion Laboratory in Southern California lost contact with the helicopter as it descended toward the surface for landing.

The Ingenuity team expected the communications dropout because a hill stood between the helicopter’s landing location and the Perseverance rover’s position, blocking communication between the two. The rover acts as a radio relay between the helicopter and mission controllers at JPL. In anticipation of this loss of communications, the Ingenuity team had already developed re-contact plans for when the rover would drive back within range. Contact was re-established June 28 when Perseverance crested the hill and could see Ingenuity again.

The goal of Flight 52, a 1,191-foot (363-meter) and 139-second-long flight, was to reposition the helicopter and take images of the Martian surface for the rover’s science team.

This image was finally received after Perseverance and Ingenuity were out of communication for 63 days.

We’re excited to be back in communications range with Ingenuity and receive confirmation of Flight 52.”

Sixty-three days is a long time to wait for the results of a flight, but the data coming in indicates all is well with the first aircraft on another world. If the remainder of Ingenuity’s health checks are equally rosy, the helicopter may fly again within the next couple of weeks.
