Did ingenuity fly on Mars?
Ingenuity, which rocketed from Earth inside the belly of the space rover Perseverance on July 30, made it to Mars in February and spent just over a week getting ready for the spotlight. Washington PostNASA again postpones historic Ingenuity helicopter flight on Mars
NASA achieved the "first powered, controlled flight on another planet" on Monday, when its. Now that history has been made, NASA is eager to tell us all about it.
NASA has set an Ingenuity postflight briefing for 11 a.m. PT today when the helicopter team will share the latest on the aviation accomplishment that took place on the red planet.
The small rotorcraft hitched a ride to Mars under the belly of the Perseverance rover, whichto fend for itself. The together. The rover acted as a witness to Ingenuity's flight.
The flight attempt was delayed from its original date of April 11 to give helicopter later successfully completed a rapid spin test, an important milestone that cleared the way for liftoff.after a spin test of the rotors ended too early. The
The agency livestreamed coverage of Ingenuity's effort on NASA TV early Monday. It wasn't like watching a sporting event with live footage, but the NASA helicopter team celebrated after getting the good news beamed back from Mars. You can catch the rerun here:
"The rover will provide support during flight operations, taking images, collecting environmental data, and hosting the base station that enables the helicopter to communicate with mission controllers on Earth," NASA said in a statement in early April.
NASA has emphasized that Ingenuity is a high-risk, high-reward technology demonstration. It is now officially delivering the reward. NASA has set the planned test flight period to last for up to 31 Earth days, and more flights could be scheduled soon. The agency is currently looking at no sooner than April 22 for a second test flight.
There's a good-luck talisman along for the ride. Ingenuity has aattached to it, drawing a direct line between the making of aviation history on both Earth and Mars.

New postponement of the first flight of an Ingenuity helicopter that faces some critical issues after being freed from the persistent rover and removed on Mars. On Saturday alone, it was announced that the first flight test would not take place before April 14, but NASA is announcing it now Waiting can take a little longer“.
But the good news is that we are only talking about a few days and that the engineers at the Jet Propulsion Laboratory have already come up with a solution. Creativity needs to update the itineraryThe operation is less liquid than expected given the distance separating the helicopter from the ground.
Remember, the malfunction occurred on April 10 during the rotary gyro test, when a watch timer safety system preventing the shift sequence from pre-flight to flight mode expired.
Once NASA received the telemetry data, it evaluated several solutions to the problem, and came to the conclusion that the modification and Reinstalling the flight program would have been the most logical path. Thus Ingenuity will be updated with new software that will modify the console boot process, allowing the necessary transition to flight mode.
In these hours, work is underway on the improved flying software, but NASA says that if updating the software isn’t a long process, the connection to creativity and uploading may take some time. Therefore, the exact date of April 14 will almost certainly be ignored, because once the creativity is updated, it will be necessary to proceed again with the rotator tests that were discontinued over the weekend.
Meanwhile, the weather conditions inside the Jezero crater remained stable and the creativity helicopter was not damaged by the temperature changes. Here’s the latest update from the MEDA station installed to persevere.
At the moment it is not possible to set specific dates, but the good news is that despite the holidays, Dexterity helicopter in excellent health. The biggest risk to his health may come from a problem with the solar panels or battery, in fact, it is necessary to keep the heaters turned on to prevent the devices from succumbing to cold Mars nights, when temperatures can drop as low as -90. Degrees Celsius.
NASA reassures its status, noting that The power, communication and heating systems are working properlyTherefore, the exact software update protocol should not face any critical issues. In fact, remember that the data path will be somewhat winding: the flux will arrive from Earth to the MRO (Mars Reconaissace Orbiter), from this to the Tenacity Wagon and from here to the Ingenuity helicopter. In total, the data will cover 280 million km.
We just have to wait with confidence for new information from NASA, and we’ll update you as soon as we learn more

“While creating a new software change is straightforward, the process of checking and finishing the upload for ingenuity will take some time.” Information. It’s just a story of days, even weeks (s). Patience.
Meanwhile, all the key signs of a drone-helicopter carrying the first controlled flight in history to another planet are “stable” at this point. The investigation continues.
“Such a technical demonstration is not surprising in the face of the challenges of having to work in real time.” NASA explains.
Originally scheduled for this weekend, The Postponed to April 14th. NASA delayed the flight, which can be described as historically significant Occurred during the last test, which saw knives Rotates at about 2,400 revolutions per minute. As NASA clarified in its press release during this large orbital test , Ended earlier than expected due to anomaly when switching from pre-flight mode to on-board system airplane mode. The ingenuity has gone into security mode. A security practice, “he said. In a safe manner Common to most space systems to avoid other breakdowns or malfunctions caused by the domino effect.
Through diligence, the helicopter hijacked all of it, To allow land controllers to understand precisely what happened.
During this first flight, It should rise three small meters above its departure zone and remain at that height for about 40 seconds before touching the bottom. If this first flight goes right, Ingenuity could fly four more planes in early May. In planes two and three, the ingenuity must be very ambitious, and must climb up to five meters and move down 50 meters to its level, i.e., stay away from perseverance to avoid any danger. Accidental conflict.
With the last two attempts, NASA is still planning ambitious, adventurous flights, but without specifying the objectivesTravel time and flight cap. Note that due to the time of several minutes of contact between the two planets, the ingenuity cannot be controlled remotely. The program for various aircraft is installed on the helicopter’s board system, but NASA can update them if needed and at any time.
These additional planes are subject to proper operationIngenuity and ingenuity Internal heating, guaranteed On-board electronics cool, with temperatures dropping to -90 That night. By far, the lowest temperature ever measured by diligence is -83 degrees Celsius.

Monday, April 19th 2021, 7:30 am - Ingenuity has achieved what was once thought to be impossible.
The day has finally arrived! Ingenuity, the little helicopter that tagged along to Mars with NASA's Perseverance rover, has now made history by achieving the first powered flight on another planet.
Ingenuity, the Mars Helicopter, is a ground-breaking technology demonstration to test powered, controlled flight on Mars. This is something that was once thought to be impossible, due to Mars' extremely thin atmosphere. The mission team has now proved that this is, indeed, possible, and this could lead to new types of exploration on Mars.
After a few delays, the Mars helicopter performed its first test flight at 3:30 a.m. ET, on Monday, April 19.
During this test, Ingenuity spun its twin rotors up to 2,500 revolutions per minute (roughly three times the rpm of helicopters on Earth). This generated enough lift for the helicopter to rise up into the air to a height of 3 metres above the ground. Ingenuity then hovered, pivoting towards Perseverance in the process, and gently lowered itself back to the ground.
"We can now say that human beings have flown a rotorcraft on another planet!" said Mimi Aung, Project Manager of the Mars Helicopter Ingenuity at NASA's Jet Propulsion Laboratory.
The data from this flight was relayed to Earth via Perseverance and the Mars Reconnaissance Orbiter, arriving shortly after 6:30 a.m. ET. The data to confirm the successful test consisted of a simple graph that showed the helicopter's altitude with time.
Images taken by the downward-facing cameras on the helicopter were also transmitted back to Earth.
Watch the replay of the Ingenuity team receiving the data, beloww.
Originally, Ingenuity was scheduled for its first test flight on Sunday, April 11. In the days leading up to this, however, it ran into a problem while testing its systems.
According to NASA, "During a high-speed spin test of the rotors on Friday, the command sequence controlling the test ended early due to a 'watchdog' timer expiration. This occurred as it was trying to transition the flight computer from 'Pre-Flight' to 'Flight' mode. The helicopter is safe and healthy and communicated its full telemetry set to Earth."
Based on this, the first flight was delayed until at least April 14.
In an update on April 12, NASA said that they found a way to program a solution to the problem that occurred. This required the new program to be validated and transmited to Ingenuity, and then the tiny drone would be rebooted for the new programming to take effect. Since this process was expected to take some time to complete, they delayed the date of the first test flight sometime during the week of April 19.
While several missions so far can be said to have 'flown' through Mars' atmosphere, everything that came before Ingenuity would be more appropriately called 'controlled falling'.
Ingenuity was the first attempt at true powered, controlled flight on another planet.
So, why even test such a thing?
With powered flight an actual possibility on Mars, this opens up a new facet to surface missions that we haven't explored yet. Perhaps in the future, every new rover or lander will include a helicopter companion that can quickly explore and scout around where its primary is located. Or, perhaps we fill a Pathfinder-style lander with a swarm of helicopters that can fan out and quickly explore a wide area in a short amount of time.
Mars does not have the best environment for flight. It's cold and dusty, and this combination can put off some impressive static charge. These conditions can test the electronic hardware of any robot, especially that of a small helicopter drone.
The biggest challenge that Ingenuity faced, though, was the planet's atmosphere. The atmosphere of Mars has less than one per cent of the surface pressure of Earth's atmosphere.
This has been a challenge for all missions that have landed on the planet. There's just barely enough air there for heat shields and parachutes to function properly, so every mission has needed something extra beyond those measures. For Pathfinder & Sojourner, Spirit, and Opportunity, airbags allowed the robots to bounce across the surface and eventually roll to a stop. The more massive Curiosity and Perseverance rovers required the impressive 'powered sky crane' maneuvers to touch down intact and safe.
Ingenuity attempted something none of these other missions had tried, though.
Now, the mission team didn't going into this blindly, of course. They tested Ingenuity in a special chamber at the Jet Propulsion Laboratory, known as the Space Simulator. In this immense sealed chamber, they recreated the cold, low-pressure atmospheric conditions that Ingenuity will encounter on Mars and then tailored the small helicopter to fly in those conditions.
The question of whether it will actually work in the real environment has now been answered! Watch for more updates in the days to come.
