The Perseverance rover, which relays data between the helicopter and Earth during the flights, showed that Ingenuity climbed to its assigned maximum altitude of 40 feet, NASA said.

During its planned descent, the helicopter and rover stopped communicating with each other.

But good news came late on Saturday, when NASA's Jet Propulsion Laboratory tweeted that it had reestablished contact with the helicopter after instructing the rover "to perform long-duration listening sessions for Ingenuity's signal." 

The Ingenuity team is reviewing the new data to understand the unexpected communications dropout that occurred during the helicopter's 72nd flight, it added.

Ingenuity has already exceeded its original mission,
