NASA’s Ingenuity Roter planet (umgangssprachlich) helicopter already been supposed to take to the Martian sky for the 14th days on September 18 but perform a brief hover the flight that would have demonstrated the little chopper’s ability to fly with a bit of higher rotor speeds. Nonetheless during its automatic pre-flight checkout, Ingenuity detected a anomaly in two of the miscroscopic flight-control servo motors and aborted the operation.
Ingenuity was ready to begin flying with a more lofty rotor speed to compensate pertaining to decreasing atmospheric density brought on by seasonal changes on Roter planet (umgangssprachlich). Step one was to perform a excessive spin test at only, 800 revolutions per minute (RPM) on the surface and, if everything gone well, step two was to perform a short-duration flight at 10 feet (5 meters) cime with a 2, 700 REVOLTIONS PER MINUTE rotor speed rather than the general 2, 537 RPM.
On September short minutes, the Mars helicopter excellently completed the high-speed ” spin ” test. Ingenuity’s motors content spinner the rotors up to merely two, 800 RPM, briefly transported that speed, and then content spun the rotors back down to one stop, all exactly as sequenced for the test. The valuable high-speed spin gave america the green light to check out a test flight with a 1 . 5, 700 RPM rotor reliability. At least, that was the plan.
After that, however , your current Ingenuity Mars helicopter did not take off due to an abnormality with its two “servos, ” electric position control gear that change the pitch from your rotors – and terminated the flight. While the servo motors are much smaller than the exact motors that spin typically the rotors, they do a tremendous amount of work and are critical to immobile, controlled flight. Because of their criticality, Ingenuity performs an automated weight and dimensions the servos before just about every single flight. This self-test kept informed the six servos by way of a sequence of steps throughout their range of motion and measures that they reach their led positions after each step.
The data collected caused by NATIONAL AERONAUTICS AND SPACE ADMINISTRATION shows that a pair of the upper rotor swashplate servo motors began to oscillate with an plenitude of approximately 1 degree of the commanded positions just after the second place step of the sequence. Ingenuity’s software detected this vacillation and promptly canceled you see, the self-test and flight.
Currently, NASA is regarded as testing the cause of the abnormality. To gather more data, that Ingenuity team executed alot more servo wiggle tests in the past week, which were successful, meaning that the issue isn’t entirely repeatable.
“Our team will have a few weeks vitality to complete our analysis only Mars will be in energy conjunction until mid-October, and now we won’t be uplinking any type of command sequences to Effectiveness during that time, ” wrote Jaakko Karras, deputy processes lead for the mission by visiting NASA’s Jet Propulsion Laboratory. The conjunction is a super period in which Mars decisions behind the Sun (as available from Earth), making interactions with spacecraft from Mars unreliable.
Now, all the mission organization can do is wait and watch how Ingenuity performs about an extended period of relative in-activity on Mars.
