The Fort Worth Press - NASA's Mars helicopter 'phones home' after no contact for 63 days

The mini rotorcraft, which hitched a ride to the Red Planet with the Perseverance rover in early 2021, has already survived well beyond its initial 30-day mission to prove the feasibility of its technology in five test flights.

Since then, it has been deployed dozens of times, acting as an aerial scout to assist its wheeled companion in searching for signs of ancient microbial life from billions of years ago, when Mars was much wetter and warmer than today.

Ingenuity's 52nd flight launched on April 26, but mission controllers at NASA's Jet Propulsion Laboratory (JPL) in California lost contact as it descended to the surface following its two minute, 1,191-foot (363-meter) hop.

The loss of communications was expected, because a hill stood between Ingenuity and Perseverance, which acts as a relay between the drone and Earth.

Nonetheless, "this has been the longest we've gone without hearing from Ingenuity so far in the mission," Joshua Anderson, Ingenuity team lead at JPL, told AFP.

"Ingenuity is designed to take care of itself when communication gaps like this occur, but we all still had a sense of relief finally hearing back."

Data so far indicates that the heli is in good shape. If further health checks also come back normal, Ingenuity will be all set for its next flight, westward toward a rocky outcrop the Perseverance team is interested in exploring.

It's not the first time Ingenuity has experienced downed communications. The heli was scouring an ancient river delta when it went missing for around six days in April, "an agonizingly long time," chief engineer Travis Brown wrote in a blog post.
