NASA’s Ingenuity helicopter made spaceflight history on Monday when it lifted off Mars and rose 10 toes above the planet’s floor. Never earlier than had a spacecraft carried out a managed, powered flight on one other planet.
Then on Thursday, Ingenuity flew even larger -16 toes – and moved sideways for the first time.
Ingenuity has confirmed that aerial exploration is potential on different planets, however its mission is far from over. Now NASA desires to acquire as a lot flight information as potential to inform future space-helicopter efforts.
In up to three extra flights over the subsequent two weeks, Ingenuity’s controllers plan to push the helicopter as far and fast as it will go. In the course of, they count on Ingenuity will crash.
“We really want to push the rotorcraft flights to the limit and really learn and get information back from that,” MiMi Aung, the undertaking supervisor for Ingenuity, stated in a Monday press briefing.
“That information is extremely important,” she added. “This is a pathfinder. This is about, you know, finding if there any ‘unknown unknowns’ that we can’t model. And we really want to know what the limits are. So we will be pushing the limits, very deliberately.”
‘Going actually far and actually fast’
During Ingenuity’s first flight, the 4-pound area drone powered up its rotors, spinning them 5 occasions quicker than a helicopter on Earth. This gave it sufficient raise in the skinny Martian ambiance to hover, pivot towards the onlooking Perseverance rover, and gently decrease itself to the floor.
During the second flight, Ingenuity tilted itself 5 levels – sufficient for the rotors’ thrust to push it sideways for about 7 toes earlier than stopping to hover.
For its subsequent flight, the helicopter will fly a lot farther and quicker. It’s set to enterprise about 165 toes out and again at a velocity of 6.5 toes per second.
“I care about going really far and really fast,” Aung stated. “As fast as we can go.”
The fifth and last enterprise might take Ingenuity up to 16 toes excessive and laterally throughout 980 toes of Martian floor, in accordance to NASA’s web site. Aung, nonetheless, stated she would “love” to push it over 2,000 toes.
By the fifth flight, the helicopter “would be unlikely to land safely, because we’ll start going into un-surveyed areas,” Aung stated in a preflight briefing on April 9.
“If we do have a bad landing, that will be the end of mission,” she added. “The lifetime will be determined by how well it lands, pretty much.”
A looming deadline for the subsequent three flights
Based on how the third flight goes, NASA’s Ingenuity team will determine how far to push the helicopter for its last two excursions.
Aung did not specify how fast she would need the helicopter to fly in later escapades. Speeding up will problem the chopper’s mechanics as effectively as its navigation system.
“We navigate by taking images of the ground below. And as we’re traveling faster over the ground, the features in those images disappear from you faster,” Håvard Grip, Ingenuity’s chief pilot, stated in the post-flight briefing.
The NASA engineers are pushing themselves over the subsequent two weeks, too. Preparations and a delay brought on by a software issue consumed the first two weeks of their 30-day window to conduct up to 5 flights. Now, lower than two weeks stay earlier than Perseverance has to proceed on its predominant alien-fossil-hunting mission.
“I believe we have enough time to squeeze the next four flights in the next few weeks left,” Aung stated on Monday. “So that’s the plan.”
