Mars Helicopter Attached to Perseverance Rover for July Launch

With the launch period of NASA's Mars 2020 Perseverance rover opening in 14 weeks, final preparations of the spacecraft continue at the Kennedy Space Center in Florida. In the past week, the assembly, test and launch operations team completed important milestones, fueling the descent stage — also known as the sky crane — and attaching the Mars Helicopter, which will be the first aircraft in history to attempt power-controlled flight on another planet.

After the descent stage fueling, the system that will deliver the Mars Helicopter to the surface of the Red Planet was integrated with Perseverance. The helicopter, which weighs 4 pounds (1.8 kilograms) and features propellers 4 feet (1.2 meters) in diameter, is cocooned within the delivery system. In one of the first steps in the day-long process on April 6, technicians and engineers made 34 electrical connections between the rover, the helicopter and its delivery system on the rover's belly. After confirming data and commands could be sent and received, they attached the delivery system to the rover.

Finally, the team confirmed the helicopter could receive an electrical charge from the rover. Before being deployed onto the surface of Jezero Crater, the Mars Helicopter will rely on the rover for power. Afterward, it will generate its own electrical power through a solar panel located above its twin counter-rotating propellers.

The helicopter will remain encapsulated on the rover's belly for the next year and will be deployed around the beginning of May — roughly two-and-a-half months after Perseverance's landing. Once the rover drives about 330 feet (100 meters) away and the helicopter undergoes an extensive systems check, it will execute a flight-test campaign for up to 30 days.

The Perseverance rover is a robotic scientist weighing 2,260 pounds (1,025 kilograms). It will search for signs of past microbial life, characterize the planet's climate and geology, collect samples for future return to Earth and pave the way for human exploration of the Red Planet. No matter what day Perseverance launches during its July 17-Aug. 5 launch period, it will land on Mars' Jezero Crater on Feb. 18, 2021.
