NASA has delayed the primary flight of its Ingenuity Mars helicopter after a vital test-spin of the drone’s rotor blades abruptly stopped.
This was the final main take a look at to ensure the helicopter can be prepared for its first flight, which was initially scheduled for early Monday.
Now NASA has delayed the historic liftoff — which might mark the primary powered, managed flight on one other planet – to Wednesday.
For the take a look at on Friday, Ingenuity was imagined to spin its blades at full pace whereas on the bottom.
The 2 pairs of blades ought to have spun in reverse instructions at greater than 2,500 rotations per minute – about eight instances sooner than an Earth helicopter.
On flight day, they will want that pace to raise the 4-pound drone into the skinny Martian ambiance.
That air has simply 1 p.c the density of Earth’s ambiance, making Ingenuity’s process the equal of flying 3 times greater than the height of Mount Everest.
However that take a look at spin was abruptly halted when a “watchdog” timer expired, NASA announced on Saturday.
This timer ended the command sequence that was instructing Ingenuity to conduct every step of the take a look at. The cease occurred because the command sequence was making an attempt to transition the helicopter’s flight laptop from “pre-flight” to “flight” mode.
“The watchdog timer oversees the command sequence and alerts the system to any potential points. It helps the system keep protected by not continuing if a problem is noticed and labored as deliberate,” NASA’s announcement mentioned.
It is not but clear what the problem was, however NASA mentioned the helicopter is “protected and wholesome” and totally speaking with mission controllers on Earth.
The company’s helicopter crew is reviewing information from the take a look at to diagnose the problem. NASA must reattempt the full-speed spin earlier than Ingenuity can fly.
Ingenuity might fly as much as 5 instances on Mars
Ingenuity traveled practically 300 million miles to Mars tucked contained in the stomach of the Perseverance rover.
It has efficiently unfolded itself from its underbelly hideaway, dropped to the bottom, survived frigid Martian nights by itself, charged up with photo voltaic power, and performed a collection of system checks.
All of the checkouts and assessments had gone properly till Friday’s full-speed spin.
“Up to now so good, knock on wooden,” MiMi Aung, the challenge supervisor for Ingenuity, mentioned in a briefing earlier than that ultimate take a look at on Friday.
For its first flight, Ingenuity is meant to raise itself about 10 ft into the air, hover, then decrease itself safely again to the bottom. If that goes properly, Ingenuity might try as much as 4 extra more and more tough flights.
“We’re all form of slightly bit nervous and excited on the similar time,” Thomas Zurbuchen, the company’s affiliate administrator for science, informed Insider on Friday. “We’re all prepared, however we’ll all really feel higher when it is executed – and profitable.”
It is a flight experiment, meant to show that rotorcraft expertise can work on Mars.
If it succeeds, it might open the door for future space-helicopters to check areas that rovers cannot attain – mountains, canyons, and rocky terrains – and even do reconnaissance for future Mars astronauts.
“Suppose that it does, in truth, work. What we could have confirmed is that we will add an aerial dimension to discovery and exploration on Mars,” Zurbuchen mentioned. “That aerial dimension, after all, opens up facets of science and general exploration that, frankly, at this second in time, are solely our desires.”
