NASA’s Ingenuity Mars Helicopter Succeeds in Historic First Flight<\/h1>\n<\/header>\n

The small rotorcraft made history, hovering above Jezero Crater, demonstrating that powered, controlled flight on another planet is possible.<\/i><\/p>\n

\n

Monday, NASA\u2019s Ingenuity Mars Helicopter became the first aircraft in history to make a powered, controlled flight on another planet. The Ingenuity team at the agency\u2019s Jet Propulsion Laboratory in Southern California confirmed the flight succeeded after receiving data from the helicopter via NASA\u2019s Perseverance Mars rover at 6:46 a.m. EDT (3:46 a.m. PDT).<\/p>\n

\u201cIngenuity is the latest in a long and storied tradition of NASA projects achieving a space exploration goal once thought impossible,\u201d said acting NASA Administrator Steve Jurczyk. \u201cThe X-15<\/a> was a pathfinder for the space shuttle. Mars Pathfinder and its Sojourner rover did the same for three generations of Mars rovers. We don\u2019t know exactly where Ingenuity will lead us, but today\u2019s results indicate the sky \u2013 at least on Mars \u2013 may not be the limit.\u201d More: https:\/\/mars.nasa.gov\/news\/8923\/nasas-ingenuity-mars-helicopter-succeeds-in-historic-first-flight\/<\/a><\/p>\n

**************<\/h1>\n

Less than a day after NASA\u2019s Mars 2020 Perseverance rover successfully landed on the surface of Mars, engineers and scientists at the agency\u2019s Jet Propulsion Laboratory in Southern California were hard at work, awaiting the next transmissions from Perseverance. As data gradually came in, relayed by several spacecraft orbiting the Red Planet, the Perseverance team were relieved to see the rover\u2019s health reports, which showed everything appeared to be working as expected.<\/p>\n

Adding to the excitement was a high-resolution image taken during the rover\u2019s landing. While NASA\u2019s Mars Curiosity rover sent back a stop-motion movie of its descent<\/a>, Perseverance\u2019s cameras are intended to capture video of its touchdown and this new still image was taken from that footage, which is still being relayed to Earth and processed.<\/p>\n

(CNN) — <\/cite>The Ingenuity helicopter, sidekick and traveling companion of NASA’s Perseverance rover, has checked in with a good report and is “operating as expected,” according to the agency.<\/p>\n<\/div>\n

If successful, Ingenuity will be the first helicopter to fly on another planet, leading to an “extraterrestrial Wright Brothers moment,” said Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate.<\/p>\n

The rover landed safely<\/a> on the surface of Mars Thursday after launching from Earth on July 30. Perseverance has already sent back an impressive set of images to show that she’s safe and ready to go through a “checkout” phase before starting her journey across the surface.<\/p>\n

Now, the mission team has heard directly from the helicopter for the first time — and it’s good news.<\/p>\n

Ingenuity is currently tucked up beneath the rover and attached to Perseverance’s belly. The rover is about the size of an SUV, while the helicopter only weighs about 4 pounds.<\/p>\n

<\/div>\n<\/div>\n

Incredible new images shared by Perseverance rover after Mars landing<\/a><\/span><\/p>\n<\/div>\n<\/div>\n

The helicopter was able to phone home via the rover by sending data back through NASA’s Mars Reconnaissance Orbiter, which acts as a communications relay between Mars and Earth and has been orbiting the red planet since 2006.<\/p>\n

Ingenuity is comfortable where it is and isn’t letting go of the rover anytime soon for a test flight. The helicopter will remain snug with the rover for 30 to 60 days.<\/p>\n

“Ingenuity, the Mars Helicopter I carry, is working as expected. I’m currently charging it, but once I set it down, it’ll rely solely on its solar panels. If it survives the brutally cold Martian nights, the team will attempt flight,” read a tweet<\/a> from the Perseverance Twitter account.<\/p>\n

“There are two big-ticket items we are looking for in the data: the state of charge of Ingenuity’s batteries as well as confirmation the base station is operating as designed, commanding heaters to turn off and on to keep the helicopter’s electronics within an expected range,” said Tim Canham, Ingenuity Mars Helicopter operations lead at NASA’s Jet Propulsion Laboratory, in a statement.<\/p>\n

“Both appear to be working great. With this positive report, we will move forward with (Saturday’s) charge of the helicopter’s batteries.”<\/p>\n

Ingenuity needs to power up and store energy so it can keep itself warm and maintain other vital functions during the cold Martian nights once the rover deposits the helicopter on the red planet’s surface. Then, Ingenuity will be on its own.<\/p>\n

\"The<\/a><\/p>\n

<\/div>\n<\/div>\n

The Mars rover landing was the happy moment we all needed<\/a><\/span><\/p>\n<\/div>\n<\/div>\n

And it will need to withstand nights where temperatures can drop as low as negative 130 degrees Fahrenheit. As Elton John famously sings in “Rocket Man,” Mars is, indeed, as cold as hell.<\/p>\n

Maintaining function and good battery health will be critical if the helicopter is to survive the frigid Martian climate before attempting any test flights later on. A total of five test flights are planned over a 31-day period once the rover finds the right “helipad,” or nice flat spot, to deposit Ingenuity.<\/p>\n

As long as Ingenuity is attached to Perseverance, the helicopter can give its batteries a boost. The helicopter has six lithium-ion batteries. Once it has detached from the rover, those batteries will be charged by the helicopter’s solar panel.<\/p>\n

The first flight of Ingenuity will be short, only about 20 seconds of hovering off the ground. But it will be a historic moment. Much like the very first Martian rover, Sojourner, Ingenuity is a technology demonstration — an experiment. Proving that this concept can work could lead to the development of rotorcraft that could act as scouts for both rovers and human missions to Mars in the future.<\/p>\n

If that first flight is successful, “over 90% of the project’s goals will have been achieved,” according to NASA.<\/p>\n

Subsequent flights could last longer and test out more of the helicopter’s capabilities. It carries two cameras that can provide aerial images. Perseverance will also train its cameras on Ingenuity to capture the sights and sounds, including video, of these historic flights.<\/p>\n

“We are in uncharted territory, but this team is used to that,” said MiMi Aung, project manager for the Ingenuity Mars Helicopter at JPL, in a statement. “Just about every milestone from here through the end of our flight demonstration program will be a first, and each has to succeed for us to go on to the next. We’ll enjoy this good news for the moment, but then we have to get back to work.”<\/p>\n

Peu avant 22h, ce 18 f\u00e9vrier, tous les yeux de la communaut\u00e9 scientifique seront braqu\u00e9s sur Mars. Le rover Pers\u00e9v\u00e9rance arrivera au-dessus du crat\u00e8re Jezero sur la plan\u00e8te rouge, apr\u00e8s six\u00a0mois de voyage.

L\u2019objectif de la mission Mars 2020 est de ramener des \u00e9chantillons du sol de la plan\u00e8te Mars sur Terre pour permettre leur analyse.<\/p>\n<\/div>\n

\n

Pour mener \u00e0 bien sa mission, Pers\u00e9v\u00e9rance sera dot\u00e9 d\u2019outils encore plus perfectionn\u00e9s que Curiosity.<\/p>\n

SuperCam …. et Super micro<\/h2>\n

\u00c0 commencer par SuperCam, la version am\u00e9lior\u00e9e de ChemCam, la cam\u00e9ra de Curiosity, pour pouvoir analyser les min\u00e9raux. Gr\u00e2ce \u00e0 la technologie d\u2019imagerie couleur haute-r\u00e9solution qu\u2019il embarque, l\u2019instrument \u00e9tudiera la chimie et la min\u00e9ralogie des roches et des sols de Mars, ainsi que la composition de son atmosph\u00e8re.

 <\/p>\n

C\u2019est environ deux \u00e0 trois jours apr\u00e8s l\u2019atterrissage que le micro con\u00e7u par l\u2019ISAE-SUPAERO commencera \u00e0 enregistrer les sons martiens. Il s\u2019agit l\u00e0 d\u2019une premi\u00e8re mondiale. Il y a d\u00e9j\u00e0 eu plusieurs tentatives d\u2019embarquer un microphone \u00e0 bord d\u2019une mission vers Mars, toutes infructueuses, et c\u2019est la premi\u00e8re fois que la NASA en s\u00e9lectionne un pour sa plus-value scientifique. Cela fait cinq ans qu’une \u00e9quipe de cinq personnes de l\u2019Isae-Supaero, l’une des meilleures \u00e9coles au monde en mati\u00e8re d’ing\u00e9nierie a\u00e9rospatiale, travaille sur ce projet.<\/p>\n

Ce microphone est en fait un mod\u00e8le “grand public” sp\u00e9cifiquement adapt\u00e9 pour r\u00e9sister \u00e0 l\u2019environnement martien. Comme l’indique David Mimoun, responsable scientifique du microphone et professeur \u00e0 l’Isae-Supaero, “un certain nombre de composants ne sont pas compatibles avec le spatial, comme le “vide spatial”, les fortes amplitudes thermiques”.<\/em><\/p>\n

Le micro doit \u00eatre capable de tenir les -120\u00b0C tout comme les +60\u00b0C sans se d\u00e9grader. On l’a chauff\u00e9 et refroidi plus de 1000 fois et pass\u00e9 aux radiations pour simuler le trajet fait entre la Terre et Mars.<\/p>\n

David Mimoun, responsable scientifique du microphone et professeur \u00e0 l’Isae-Supaero<\/p>\n<\/blockquote>\n

David Mimoun ajoute qu'”une seconde adaptation a \u00e9t\u00e9 n\u00e9cessaire. Il a fallu un fil sp\u00e9cial pour le raccorder \u00e0 SuperCam qui l’alimente. Le micro \u00e9tant \u00e0 l’ext\u00e9rieur du rover, le cable subit donc le froid intense \u00e0 l’ext\u00e9rieur et le chaud \u00e0 l’int\u00e9rieur. Ce fil sp\u00e9cial conduit l’\u00e9lectricit\u00e9 mais pas la chaleur”<\/em>. Par ailleurs des soudures tr\u00e8s sp\u00e9cifiques ont \u00e9t\u00e9 r\u00e9alis\u00e9es pour adapter le microphone \u00e0 son environnement spatial.<\/p>\n

Gr\u00e2ce \u00e0 une calibration effectu\u00e9e sur Terre, dans une chambre reproduisant les conditions \u00ab martiennes \u00bb, les enregistrements effectu\u00e9s par le micro pourront aider les chercheurs de l\u2019Isae-Supaero \u00e0 caract\u00e9riser les diff\u00e9rents types de mat\u00e9riaux analys\u00e9s par l\u2019instrument SuperCam, en s\u2019appuyant sur une collection de sons de r\u00e9f\u00e9rence.<\/p>\n

Il faut savoir que le bruit sur Mars est fortement att\u00e9nu\u00e9 et ne se propage pas. Les sons sont att\u00e9nu\u00e9s de 20 dB par rapport \u00e0 leur niveau sur Terre. Cela revient \u00e0 une conversation \u00e0 travers un mur de dix cm d\u2019\u00e9paisseur.<\/p>\n

Une double mission sur une d\u00e9cennie<\/h2>\n

La mission primaire de Perseverance durera environ 22 mois terrestres apr\u00e8s l\u2019atterrissage soit jusqu\u2019au 6 janvier 2023. Tout temps suppl\u00e9mentaire sera\u00a0du \u00ab\u00a0bonus\u00a0\u00bb. Il faut savoir que la mission Mars 2020 est le premier volet d’une mission en deux parties. Pers\u00e9v\u00e9rance va, en premier lieu, collecter des informations et des \u00e9chantillons. Et d\u00e9but 2030, un rover que l’on appelle “fetcher” ira chercher les \u00e9chantillons pour les ramener sur Terre.<\/p>\n

Et pour ceux qui s’interrogent… Quid de Curiosity ? Il continue son travail tant que sa sant\u00e9 le lui permet, maintenant \u00e9paul\u00e9 par Pers\u00e9v\u00e9rance, \u00e0 l’oeuvre d’ici quelques jours sur sa mission d’envergure.<\/p>\n
