The first helicopter on Mars phones home after Perseverance rover landing
The first helicopter ever sent to another world is doing just fine on Mars after surviving a “seven minutes of terror” landing aboard NASA’s Perseverance.
The Ingenuity helicopter, which landed on Mars with Perseverance on Thursday (Feb. 18), is awake and communicating with controllers on Earth.
Controllers at NASA’s Jet Propulsion Laboratory (JPL) received a downlink on Friday at 6:30 p.m. EST (2330 GMT) through the Mars Reconnaissance Orbiter, indicating the 4-lb. (2 kilograms) helicopter and its base station are both operating normally.

“Both appear to be working great. With this positive report, we will move forward with tomorrow’s charge of the helicopter’s batteries,” Tim Canham, Ingenuity Mars helicopter operations lead at JPL, said in a statement on Friday.
That power-up procedure, which occurred Saturday (Feb. 20), will charge the six lithium-ion “rotorcraft” batteries to roughly 30% of their planned capacity, and data will be sent back to Earth to decide how to proceed with future battery-charging sessions.

For now, JPL plans to charge the batteries to 35% capacity in a few more days, and then to do weekly charging sessions to keep the helicopter warm on the cold Martian surface — and ready for its eventual flight in a few months.
Ingenuity is getting its power from Perseverance from the time being, but once the rover lets go of the helicopter, the drone will be charging fully on its own, using solar panels.
“After Perseverance deploys Ingenuity to the surface, the helicopter will then have a 30-Martian-day [31-Earth-day] experimental flight test window,” JPL said in a statement. A Martian day or “sol” is 24 hours and 37 minutes, compared to Earth’s 24 hours, and controllers are operating on Mars time for the first 90 sols of the mission.
“If Ingenuity survives its first bone-chilling Martian nights — where temperatures dip as low as minus 130 degrees Fahrenheit [minus 90 degrees Celsius] — the team will proceed with the first flight of an aircraft on another world,” JPL added. “If Ingenuity succeeds in taking off and hovering during its first flight, over 90 percent of the project’s goals will have been achieved. If the rotorcraft lands successfully and remains operable, up to four more flights could be attempted, each one building on the success of the last.”
Ingenuity’s flights could pioneer a new generation of soaring Mars explorers working either independently, or alongside far-future human landing missions. Flying drones on Mars could scout ahead of rovers to plan the best routes, or hover above dangerous terrain to perform scientific studies, among other applications.
