Delayed to no earlier than Wednesday. "Watchdog" timer expiration...

In the meantime, pretty cool seeing an actual pic of it taken on Utah by one of the rover's cams.

Bummer. This stuff is all so interesting. Sounds like it’s fine, but I wonder what it all means? Maybe they can figure it out.

Here is more;

Based on data from the Ingenuity Mars helicopter that arrived late Friday night, NASA has chosen to reschedule the Ingenuity Mars Helicopter’s first experimental flight to no earlier than April 14.

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.

The watchdog timer oversees the command sequence and alerts the system to any potential issues. It helps the system stay safe by not proceeding if an issue is observed and worked as planned.

The helicopter team is reviewing telemetry to diagnose and understand the issue. Following that, they will reschedule the full-speed test.

1% of our atmosphere. It's amazing that thing will be able to get any lift at all. Man am I hopeful we get to see a ton of vids from this. :cool: (y)

Sounds like they have no new date selected. But hope to have a new date next week.

Work Progresses Toward Ingenuity’s First Flight on Mars

The Ingenuity team has identified a software solution for the command sequence issue identified on Sol 49 (April 9) during a planned high-speed spin-up test of the helicopter’s rotors. Over the weekend, the team considered and tested multiple potential solutions to this issue, concluding that minor modification and reinstallation of Ingenuity’s flight control software is the most robust path forward. This software update will modify the process by which the two flight controllers boot up, allowing the hardware and software to safely transition to the flight state. Modifications to the flight software are being independently reviewed and validated today and tomorrow in testbeds at JPL.

While the development of the new software change is straightforward, the process of validating it and completing its uplink to Ingenuity will take some time. A detailed timeline for rescheduling the high-speed spin-up test and first flight is still in process. The process of updating Ingenuity’s flight control software will follow established processes for validation with careful and deliberate steps to move the new software through the rover to the base station and then to the helicopter. Intermediate milestones include:

• Diagnose the issue and develop potential solutions
• Develop/validate and upload software
• Load flight software onto flight controllers
• Boot Ingenuity on new flight software

Once we have passed these milestones, we will prepare Ingenuity for its first flight, which will take several sols, or Mars days. Our best estimate of a targeted flight date is fluid right now, but we are working toward achieving these milestones and will set a flight date next week. We are confident in the team’s ability to work through this challenge and prepare for Ingenuity’s historic first controlled powered flight on another planet.

Ingenuity continues to be healthy on the surface on Mars. Critical functions such as power, communications, and thermal control are stable. It is not unexpected for a technology demonstration like this to encounter challenges that need to be worked in real time. The high-risk, high-reward approach we have taken to the first powered, controlled flight on another planet allows us to push the performance envelope in ways we could not with a mission designed to last for years such as Perseverance. In the meantime, while the Ingenuity team does its work, Perseverance will continue to do science with its suite of instruments and is gearing up for a test of the MOXIE technology demonstration.

Get ready!

NASA to Attempt First Controlled Flight on Mars As Soon As Monday

NASA is targeting no earlier than Monday, April 19, for the first flight of its Ingenuity Mars Helicopter at approximately 3:30 a.m. EDT (12:30 a.m. PDT).

Data from the first flight will return to Earth a few hours following the autonomous flight. A livestream will begin at 6:15 a.m. EDT (3:15 a.m. PDT), as the helicopter team prepares to receive the data downlink in the Space Flight Operations Facility at NASA’s Jet Propulsion Laboratory (JPL). Watch on NASA Television, the agency app, website, and social media platforms, including YouTube and Facebook.

If the flight takes place April 19, a postflight briefing will be held at 2 p.m. EDT (11 a.m. PDT).

It’s possible we could see images and aerial photos this time tomorrow!

What a wild sight that could be.

Welp, it successfully completed its hover maneuver. Too bad the footage sucks worse than an animated gif from the '90s. I understand they needed the bandwidth for the engineering data more than images to plan their next test though, so it's cool.

Yeah... This is cool!

Here is another video;


View: https://youtu.be/wMnOo2zcjXA


The full story is at the link, but I captioned the next flight information below. “Expand the flight profile”... :D


Over the next three sols, the helicopter team will receive and analyze all data and imagery from the test and formulate a plan for the second experimental test flight, scheduled for no earlier than April 22. If the helicopter survives the second flight test, the Ingenuity team will consider how best to expand the flight profile.

Here is another video;

another video? it's exactly the same. they're not broadcasting a football game up there, there's only one camera.:LOL:

although it will be nice once the chopper roams around and we see video it takes of the surface of mars. i'm expecting a lot of rocks and brown dirt.

Huh. I suppose it's some kind of major breakthrough but getting it TO mars is far more impressive to me.

The next clip needs to be from the little chopper itself. AND THERE BETTER BE MARTIANS DAMN IT!!!

Well at least the video gets right to the point compared to the one I posted.

The thing is they have limited bandwidth, so they are prioritizing the engineering data which will be important for developing aircraft for future missions. That means less fun stuff for us to see. Hopefully they throw us a bone. That is if their next test doesn't crash the thing...
