    "NASA preparing to fly Ingenuity Mars drone, enabling future airborne missions"

    https://www.nasaspaceflight.com/2021...ture-missions/

    As NASA’s newest Mars rover, Perseverance, continues its own checkouts and tests, work is starting for a new phase of the mission – the Ingenuity helicopter. This first-of-its-kind piece of hardware will demonstrate (non-rocket) powered flight on a world other than Earth for the first time. Data from these flights – expected to begin in 30-60 days – will help to develop future programs for missions to Mars and beyond.


    Ingenuity is an experimental addition to the Mars 2020 mission. No matter the results of its test campaign, it will not have a significant effect on the primary mission.

    "Perseverance 'SuperCam' begins hunt for past life on Mars"

    https://www.marsdaily.com/reports/Pe..._Mars_999.html

    The bundle of instruments known as SuperCam on board the Perseverance Mars rover has collected its first samples in the hunt for past life on the Red Planet, mission scientists said Wednesday.

    The return to Earth years from now of the rocks and soil it retrieves "will give scientists the Holy Grail of planetary exploration," Jean-Yves le Gall, president of France's National Centre for Space Studies (CNES), which mostly built the mobile observatory, commented via a YouTube broadcast.

    These "pieces of Mars", he said, may "finally answer this fascinating and fundamental question: was there ever life elsewhere than Earth?"

    "Perseverance Mars Rover: Off to a “Rocky” Start?"

    https://www.leonarddavid.com/perseve...a-rocky-start/

    NASA’s latest addition to Red Planet probing is the Perseverance robot – now getting up to speed on Mars within Jezero crater. Scientists believe the area was once flooded with water and was home to an ancient river delta.

    However, early imagery relayed from Perseverance has provided some “geo…logical” head-scratching.

    "NASA's Perseverance rover sends back sounds of Martian winds and rock-blasting laser"

    https://www.abc.net.au/news/2021-03-...laser/13241260

    NASA has released audio recordings of Martian winds, captured by its Perseverance rover, which landed on the red planet on February 18.

    The data release also includes the first audio of laser zaps on another planet — as the rover's SuperCam instrument blasts Martian rocks to explore their composition — and the sounds of the rover as it begins its first tentative explorations.

    The laser sounds can give NASA's researchers an idea of the composition of the rock.

    "Perseverance SuperCam science instrument delivers first results"

    https://www.marsdaily.com/reports/Pe...sults_999.html

    The first readings from the SuperCam instrument aboard NASA's Perseverance rover have arrived on Earth. SuperCam was developed jointly by the Los Alamos National Laboratory (LANL) in New Mexico and a consortium of French research laboratories under the auspices of the Centre National d'Etudes Spatiales (CNES). The instrument delivered data to the French Space Agency's operations center in Toulouse that includes the first audio of laser zaps on another planet.

    "It is amazing to see SuperCam working so well on Mars," said Roger Wiens, the principal investigator for Perseverance's SuperCam instrument from Los Alamos National Laboratory in New Mexico. "When we first dreamed up this instrument eight years ago, we worried that we were being way too ambitious. Now it is up there working like a charm."

    The Ingenuity debris cover has been dropped in preparation to deploy the vehicle. I hope this works and gives JPL/NASA the information that was desired.

    "NASA Ingenuity Mars Helicopter prepares for first flight"

    https://www.marsdaily.com/reports/NA...light_999.html

    NASA is targeting no earlier than April 8 for the Ingenuity Mars Helicopter to make the first attempt at powered, controlled flight of an aircraft on another planet. Before the 4-pound (1.8-kilogram) rotorcraft can attempt its first flight, however, both it and its team must meet a series of daunting milestones.

    Ingenuity remains attached to the belly of NASA's Perseverance rover, which touched down on Mars Feb. 18. On March 21, the rover deployed the guitar case-shaped graphite composite debris shield that protected Ingenuity during landing. The rover currently is in transit to the "airfield" where Ingenuity will attempt to fly. Once deployed, Ingenuity will have 30 Martian days, or sols, (31 Earth days) to conduct its test flight campaign.

    NASA's Mars helicopter to make first flight attempt Sunday.

    Perserverance has dropped off Ingenuity at its launch site....
    . Thanks spjung. More details and pics...

    https://www.universetoday.com/150819...t-time-to-fly/

    https://mars.nasa.gov/news/8915/nasa...ttempt-sunday/

    If all proceeds as planned, the 4-pound (1.8-kg) rotorcraft is expected to take off from Mars’ Jezero Crater Sunday, April 11, at 12:30 p.m. local Mars solar time (10:54 p.m. EDT, 7:54 p.m. PDT), hovering 10 feet (3 meters) above the surface for up to 30 seconds. Mission control specialists at NASA’s Jet Propulsion Laboratory in Southern California expect to receive the first data from the first flight attempt the following morning at around 4:15 a.m. EDT (1:15 a.m. PDT). NASA TV will air live coverage of the team as they receive the data, with commentary beginning at 3:30 a.m. EDT (12:30 a.m. PDT).
    I look forward to it! Hope the flight goes ok.

    Yep, me too, but I'll wait for the re-runs; that's too danged early for me.

    I heard a portion of a press conference given this week by members of the Perseverance team. Engineer Tim Canham said they might aim the rover microphone at Ingenuity on the second flight to try to capture audio. Their expectations are low but they reckon it's worth a try.

    "NASA's Mars Helicopter Ingenuity's historic flight delayed"

    https://www.foxnews.com/science/nasa...istoric-flight

    NASA's Ingenuity Mars helicopter is scheduled to lift off no sooner than April 14 in the first-ever attempt at powered, controlled flight on another planet, a delay from its initial planned launch date.

    While lift-off was initially targeted for Sunday, April 11, the agency announced the delay on Saturday afternoon.

    And delayed again (does Ingenuity at least get to munch on peanuts while waiting for takeoff?)

    NASA’s Ingenuity helicopter project on Mars is having trouble getting off the ground.

    The space agency’s much-buzzed-about first powered flight on another planet has been rescheduled a second time due to technical concerns.

    Initially, NASA’s “Wright Brother’s moment” was slated for Sunday but was pushed back to Wednesday after the space agency discovered an issue with the aircraft’s rotors. Then, late Monday, NASA said it’s pushing the launch back again to modify and reinstall the copter’s flight control software.

    The situation is now “fluid,” the space administration says.

    “Ingenuity is healthy, but it needs a flight software update. While the development of the software is straightforward, validating and uplinking it will take time. We will set a new flight date next week," NASA said in a tweet.

    Ingenuity - first flight now planned for Monday 19th April...

    Another attempt to launch Ingenuity on the first powered flight on another planet.

    Up, up, and away! The Ingenuity #MarsHelicopter is set to make history. It will make the first attempt at powered flight on another planet on Monday, April 19. Don’t miss your chance to watch live with helicopter team in mission control beginning at 3:15 a.m. PDT (6:15 a.m. EDT/10:15 a.m. UTC) as they receive the data and find out if they were successful.

    Looks as if there's a considerable amount of dust Ingenuitys solar panels.

    Superluminal raises what could be a serious problem which would be a shame. I suppose its only a demonstration project which has no specific science goals and is high risk high reward, as was made clear in the 9th April NASA pre-flight press conference, which can be found in archives in my link above. But I would expect NASA to have considered solar panel dust risks given the Mars atmosphere.

    Solar Panels on the surface of the moon do not have that problem, as became apparent in a recent discussion Fraser Cain had on You Tube with Alex Ignatiev of Lunar Resources.

    But given plans to send people to Mars at some point over the next decade or two surely we need to be able to cope with the Mars atmosphere and risk of dust on solar panels!

    It does have blades that are to move at considerable speed to move a fair amount of the very thin atmosphere and it is supposed to move through the atmosphere, so it wouldn’t surprise me if it makes its own cleaning events. Spirit and Opportunity managed with considerable dust on their panels but with the occasional dust devil cleaning event. Anyway, it’s experimental, so we’ll learn what works and what needs to be changed.

    It seems strange to me to think or assume that those who have been planning Mars exploration and potential colonization have not considered aspects of dust on power generating equipment in some detail. Particularly after seeing how dust accumulates on what, at least 1/2 a dozen missions so far?

    Oh, they have considered it. There are tests of panel coatings that could electrostaticly repel dust, or drones much like Ingenuity that would hover over panels and blow the dust off of them. Of course, Perseverance uses an RTG, so it doesn’t need panel cleaning. I have no doubt some of these things will be used in time, but they’ll have to be developed and tested more. And don’t forget Spirit and Opportunity worked far beyond their warranties without any technological help with their panels. Mars gave them a helping hand.

    From what I've read, Ingenuity needs a lot of power to fly. Can't be good if it sits too long. And a dust devil might flip it over.

    Sitting for a few weeks shouldn't be a problem; the helicopter is capable of recharging itself as it needs to do after every flight anyway.

    I wouldn't think dust devils would have that kind of force? There is not a lot of atmosphere to push.
    With sufficient thrust, water towers fly just fine.

    I was thinking the same thing, and no doubt NASA teams have thought about it and modeled it, but Ingenuity is designed to be light and it does have those fairly large helicopter blades, so I don’t know if it can be completely ruled out.

    Pfff typical. A historic helicopter flight and I can't watch it in person because I just happen to be out of planet.

    For others who also happen to be on the wrong planet, there is a livestream (with 3h delay) here:

    First B/W image coming in, showing the chopper looking down at its own shadow. No dust cloud visible from hover altitude.

    Perseverance video coming in now! Not exactly 60fps stuff but it shows Ingenuity hovering and landing.
