In the end, historical past has lastly been made as humankind has made the subsequent nice stride in powered flight; the primary flight on one other planet.
On April 19, 2021, the Ingenuity helicopter efficiently took to the Martian skies in what’s hopefully the primary of as much as 5 experimental flights anticipated to happen over the length of the subsequent few weeks.
“We will now say that human beings have flown a rotorcraft on one other planet,” stated MiMi Aung, the Ingenuity Mars Helicopter challenge supervisor at NASA’s Jet Propulsion Laboratory earlier than thanking the entire workforce for his or her years of dedication on the challenge. “We, collectively, flew at Mars and we, collectively, now have our Wright brothers second.”
Aung stated historical past exhibits that quickly after their first flight in 1903 at Kitty Hawk, North Carolina, Wilbur and Orville Wright went proper again to work and flew three extra flights that day, greater and farther than the primary.
“Just like the Wright brothers at Kitty Hawk, we all know that our time to make a distinction at Jezero Crater on Mars shouldn’t be but over,” Aung stated. “That is simply the primary nice flight.”
Aung requested the workforce to take pleasure in this second and have a good time, specifically as a result of through the years for every main milestone handed, the workforce held off totally celebrating in an effort to preserve transferring ahead.
“We should take a second to have a good time this second,” Aung stated. “Take that second, after which after that, let’s get again to work and extra flights!”
You wouldn’t consider what I simply noticed.

Ingenuity’s first flight occurred about about 3:34 a.m. EST (07:34 UTC). Whereas it was the early-morning hours for controllers at JPL, it was the center of the day at Jezero crater on Mars. The autonomous flight lasted for a complete of 39.1 seconds which noticed the automobile climb to about 10 ft (Three meters) above the bottom, hover for about 30 seconds after which slowly descend again to the floor for a secure touchdown.
Instructions for the flight had been despatched to the spacecraft the day earlier than and affirmation the end result didn’t arrive till about 6:46 a.m. EDT (10:46 UTC). This was as a result of as soon as the sequence was accomplished, the helicopter and Perseverance rover, which carried Ingenuity to the pink planet, needed to uplink the information to a satellite tv for pc orbiting Mars. That satellite tv for pc then needed to relay the knowledge again to JPL by means of the Deep Area Community, a sequence of ground-based satellite tv for pc dishes positioned round Earth.
Going ahead, controllers at JPL plan to make a number of extra powered flights every incrementally longer than the one earlier than it.
The objective of those experimental flights is to pave the best way for the subsequent technology of rotorcraft autos spacecraft may in the future fly on Mars.
“Now, 117 years after the Wright brothers succeeded in making the primary flight on our planet, NASA’s Ingenuity helicopter has succeeded in performing this superb feat on one other world,” Zurbuchen stated in a NASA press release. “Whereas these two iconic moments in aviation historical past could also be separated by time and 173 million miles of area, they now will endlessly be linked. As an homage to the 2 revolutionary bicycle makers from Dayton, this primary of many airports on different worlds will now be often called Wright Brothers Discipline, in recognition of the ingenuity and innovation that proceed to propel exploration.”
Getting Ingenuity within the air
Within the days main as much as Ingenuity’s historic first flight, the helicopter was unloaded from the underside of the Perseverance rover the place it was stowed in a folded place inside a cargo field. As soon as it was totally unfolded from its stowed place, the rover “dropped” the craft from a peak of about 4 inches onto the floor of Mars.
From there, the rover needed to shortly transfer away from the helicopter to ensure that Ingenuity’s onboard photo voltaic panels to have a possibility to start charging.
Scientists on the bottom at NASA’s Jet Propulsion Laboratory in California determined to capitalize on the chance by utilizing Perseverance’s onboard robotic arm and digicam to take a “selfie” with each the Rover and Ingenuity within the background. This was the primary time two separate craft have been photographed on one other planet.
Flight controllers at JPL needed to guarantee that each system on Ingenuity was performing fully nominally earlier than the primary flight. This included making certain the automobile may survive a chilly Martian night time, cost autonomously utilizing its photo voltaic panel and spinning up the rotor blades whereas nonetheless on the floor.
Whereas a low-speed spin check was profitable, when engineers tried a high-speed spin check on April 9, an unexpected “watchdog” timer issue prevented the helicopter from transitioning to “flight mode” in an effort to carry out the check.
Engineers labored on two solutions for this problem, each of which had been verified to be used. One concerned modifying and reinstalling current flight management software program, which JPL stated has been secure and wholesome for shut to 2 years. The opposite was to regulate the command sequence to barely alter the timing of the “flight mode” transition. The previous possibility was chosen because it was the least-disruptive path ahead.
In line with an April 17 mission update, “from testing this system on Ingenuity over the previous couple of days, we all know this strategy is prone to permit us to transition to flight mode and put together for lift-off about 85% of the time. This resolution leaves the helicopter secure if the transition to flight mode shouldn’t be accomplished.”
The ultimate spin-up check occurred April 16 and concerned the 2 rotors onboard the helicopter, every measuring about 4 ft (1.2 meters) in size, being whirled as much as about 2,500 rotations per minute — about 5 instances quicker than that of a typical helicopter on Earth.
Challenges of flight on Mars
Flight on Mars specifically is difficult for quite a lot of causes, however the primary one is the thickness of the environment, which is about 1% as dense as Earths.
Due to that, Ingenuity had to be as light as possible. The helicopter has a mass of 1.eight kilograms. As such it will weigh about Four kilos on Earth. Within the low Martian gravity surroundings, it weighs about 1.5 kilos.
Even so, the rotor blades nonetheless required some 2,500 rotations per minute in an effort to get airborne. That additionally requires plenty of energy. Aboard Ingenuity are lithium-ion batteries that give sufficient power for about 90 seconds of flight.
In line with JPL, every flight requires a median of about 350 watts of energy.
Within the coming days, Ingenuity is anticipated to fly greater and farther. Finally, it’s designed to fly as much as 15 ft (5 meters) in altitude with a variety of about 980 ft (300 meters).
Because the mission is a expertise demonstration, its mission isn’t anticipated to last more than about 30 days. It’s objective is to offer invaluable information to engineers on Earth for future Mars helicopters.

Having a life-long curiosity in crewed area flight, Desforges’ ardour materialized on a household trip in 1999 when he was ready see the launch of Area Shuttle Discovery on STS-96. Since then, Desforges has been an fanatic of area exploration efforts. He lived in Orlando, Florida for a 12 months, throughout which era he had the chance to witness the flights of the historic CRS-Four and EFT-1 missions in particular person at Cape Canaveral.
