A software issue may have prevented the helicopter's flight computer from transitioning to flight mode, so the Ingenuity team has said it will attempt the fourth flight again on Friday.
NASA scientists have planned for the rotorcraft to attempt five flights in total, but they won't be surprised if it crashes in the process, since they're about to push the helicopter as far and fast as it will go in these last two flights.
"We really want to push the rotorcraft flights to the limit and really learn and get information back from that," MiMi Aung, the project manager for Ingenuity, said in a recent briefing.
Aung's team hopes Ingenuity can work up to flying laterally across 980 feet of Martian ground.
