NASA’s Mars helicopter Ingenuity shall be making an attempt one other take a look at flight this weekend, spinning its rotors quicker than in any flight earlier than to compensate for the altering climate on Mars.
In a tweet posted on Friday, October 22, NASA’s Jet Propulsion Laboratory (JPL) confirmed that they have been planning to renew Ingenuity take a look at flights as quickly as immediately, Saturday October 23. The engineers shall be making an attempt out a brief flight utilizing the next rotor pace for flight quantity 14.
🚁 Now that conjunction is over, #MarsHelicopter can try flight 14. Ingenuity efficiently carried out a 50 rpm spin take a look at this week & will do a brief hop no sooner than Oct. 23. That is to check out flying in decrease atmospheric densities on the Purple Planet https://t.co/IC4W3xgSV9 pic.twitter.com/zl5KVPgfut

Ingenuity must spin its rotors quicker than it has carried out beforehand as a result of modifications within the Martian climate. The unique plan for the helicopter was to carry out simply 5 flights, nevertheless it has been so successful that the workforce has continued with additional and extra complicated flights. However which means they have to now take care of altering Martian seasons.
The environment on Mars is already very skinny, at round 1% of the density of the environment on Earth, however seasonal modifications imply that it’s now getting even thinner. The thinning of the environment is an issue for Ingenuity, which flies by spinning its rotors to maneuver the air and preserve itself aloft.
To take care of this thinning environment, the JPL workforce plans to spin Ingenuity’s rotors even quicker to generate extra raise through the flight. Nonetheless, this entails spinning up the rotors to speeds by no means tried throughout testing on Earth. Spinning them too quick might result in issues by creating an excessive amount of drag or by creating resonances that shake the helicopter.
To ensure it was protected to spin the rotors at speeds of as much as 2,800 rpm, the workforce carried out a high-speed spin take a look at final month. Every thing went effectively, and JPL reported that the methods carried out “flawlessly.”
The plan had been to go forward with take a look at flight 14 utilizing rotor speeds of as much as 2,700 rpm, however this was delayed because of the detection of a minor anomaly. Then there was an extra delay because of the Mars photo voltaic conjunction, when Earth and Mars are on reverse sides of the solar which makes sending radio alerts tough. Ingenuity, like NASA’s different Mars explorers, took a two-week break over this era whereas engineers waited for communications to be safely resumed.
Now that wait is over, and Ingenuity can get again to its formidable, high-rotor-speed take a look at flight 14. The flight shall be only a quick hop to make sure that flight nonetheless works, even with the decrease atmospheric densities.
