NASA's Mars Ingenuity helicopter forgot its fourth planned flight, with the space agency accusing a software glitch and pledging to try also the successive day.

'The helicopter is protected and in fair health,' explained in an announcement, expanding the rotorcraft had declined to transition to 'flight mode.' 

The committee schedules to strive the flight formerly additional on Friday at 10:46 am Eastern Time (8:16 pm IST) with data anticipated behind at NASA's Jet Propulsion Laboratory around 3 hours deceased.

The software problem is supposed to be the similar one that postponed Ingenuity's maiden journey, the initial powered flight on another planet. Initially planned for April 11, the memorable undertaking happened April 19.

The justification was a glitch correlated with the aircraft's 'watchdog timer,' which awakens Ingenuity to potential difficulties and halts its methods if it believes it has observed an error.

Engineers brought in a coding tweak that authorized Ingenuity to withstand the difficulty and growth to flight method correctly - but calculated there was a 15 % chance it would not help on each flight undertaking.
