Ingenuity Update from PerseveranceRover

Ingenuity Update

https://mars.nasa.gov/technology/helicopter/status/290/work-progresses-toward-ingenuity-s-first-flight-on-mars/

“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.”

A copy of the Blog in case anyone has issues opening it:-

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.

Over the weekend while everyone was distracted by the excited news from Curiosity’s younger siblings (myself included!), Curiosity performed a fairly extensive check-up on 4 of its 6 wheels using the MAHLI instrument. Each of the 4 wheels were photographed 4 times, each time rolling the wheel a bit to image the entire wheel. 2 of the wheels photographed have extensive damage while the other two only have dents and a few small punctures.

You can view all 16 images at the raw image site, filtered for MAHLI images taken on Sol 3079 or if you prefer in an imgur gallery here.

NASA’s Mars Helicopter Survives First Cold Martian Night on Its Own

Making it through the frigid Martian temperatures after being deployed by NASA’s Perseverance rover is a major milestone for the small rotorcraft.

NASA’s Mars Helicopter Survives First Cold Martian Night on Its Own

NASA’s Ingenuity Mars Helicopter has emerged from its first night on the surface of Mars.

 

Evening temperatures at Jezero Crater can plunge as low as minus 130 degrees Fahrenheit (minus 90 degrees Celsius), which can freeze and crack unprotected electrical components and damage the onboard batteries required for flight. Surviving that first night after being deployed from where it was attached to the belly of NASA’s Perseverance rover on April 3 is a major milestone for the 4-pound (1.8 kilograms) rotorcraft. In the days to come, Ingenuity will be the first aircraft to attempt powered, controlled flight on another planet.

 

“This is the first time that Ingenuity has been on its own on the surface of Mars,” said MiMi Aung, Ingenuity project manager at NASA’s Jet Propulsion Laboratory in Southern California. “But we now have confirmation that we have the right insulation, the right heaters, and enough energy in its battery to survive the cold night, which is a big win for the team. We’re excited to continue to prepare Ingenuity for its first flight test.”

 

Devising a craft small enough to fit onto the rover, light enough to fly in Mars’ thin atmosphere, yet hardy enough to withstand the Martian cold presented significant challenges. To ensure the solar array atop the helicopter’s rotors could begin getting sunlight as soon as possible, Perseverance was instructed to move away from Ingenuity shortly after deploying it.

Curiosity Rover Mission Update for Sols 3076-3077:

Dancing Around ‘Mont Mercou’

Written by Mark Salvatore, Planetary Geologist at University of Michigan

March 31, 2021.

Curiosity is continuing her investigation of “Mont Mercou,” the tall outcrop of bedded sedimentary rock seen in the attached image. The science team has been navigating around the base of the cliff after having successfully drilled into the “Nontron” bedrock target last week. By imaging the cliff at different viewing geometries, we are able to change both position and illumination conditions, helping us to fully map the observed structures and properties of these sedimentary rocks.

In this plan, the team has identified a nodular bedrock target to characterize using the APXS instrument on the rover’s arm, which will provide information about the chemical make-up of this bedrock material. Curiosity will also be acquiring many images using both the ChemCam and Mastcam instruments, as we are now on the eastern side of the cliff face. Following these observations, Curiosity will then navigate to the western side of the cliff face to perform a similar suite of imaging observations.

As has been mentioned in previous posts, these sorts of rock outcrops, where we can see bedding from multiple angles, are a treasure for geologists as we try to unravel the ancient environmental conditions that were once present in Gale crater. The team is cognizant of the value of this outcrop, and so we are making sure to acquire all of the observations that we need before driving away from this location.

For The First Time, Twisted Light Reveals Magnetic Fields Around The Black Hole M87*

M87* is the Black Hole that grabbed our attention in 2019 when astronomers published the first direct image of a Black Hole captured by the Event Horizon Telescope , since then they have continued to analyse the data leading to the discovery that the image contains evidence of light being twisted by the gravitational forces of the Black Hole.

Now, scientists with the Event Horizon Telescope collaboration have carefully analyzed that glowing ring of golden light from 55 million light-years away, and found evidence of strong polarization – the twisting of the orientation of the light waves, generated by powerful magnetic fields in the region around the black hole.

“This work is a major milestone: the polarization of light carries information that allows us to better understand the physics behind the image we saw in April 2019, which was not possible before,” said astronomer Iván Martí-Vidal of the University of Valencia in Spain.

“Unveiling this new polarized-light image required years of work due to the complex techniques involved in obtaining and analyzing the data.”

Polarization is a well known and understood behavior of electromagnetic radiation. As a particle of light travels through space, its oscillations are oriented in a certain direction. If it is scattered by, for example, dust in the interstellar medium, or rotated by a magnetic field, its orientation can change; we call that change polarization.

Aside from being a pretty picture the discovery could help unlock long held secrets of Black Holes.

This could be key to understanding a phenomenon that has long proven to be a puzzle – relativistic black hole jets.

Nothing that we can currently detect can escape a black hole once it’s passed the critical proximity threshold, but not all the material in the accretion disk swirling into an active black hole inevitably ends up beyond the event horizon. A small fraction of it somehow gets funneled from the inner region of the accretion disk to the poles where it is blasted into space in the form of jets of ionized plasma, at speeds a significant percentage of the speed of light.

Astronomers think that the black hole’s magnetic field plays a role in this process. The magnetic field lines, according to this theory, act as a synchrotron that accelerates material before launching it at tremendous speed.

Curiosity Rover Mission Update for Sol 3068:Time to Re-Gift.Written by Scott Guzewich, Atmospheric Scientist at NASA’s Goddard Space Flight Center

March 24, 2021.

It takes careful planning to manage the rover’s battery and power, much like we all manage our cell phone batteries and try to keep them charged. But we have to plan several sols ahead. The analogy would be if we had to plan ahead three days when we wanted to stream a TV show on our phone and knowing we’d only be able to charge it that day from 7-8 a.m. Usually when we plan a SAM activity (this is a recent Mastcam image of the SAM inlet covers), like yesterday, we expect a power “gift” in the next sol where SAM does not use as much power as we budgeted. Yesterday, that was not the case, and combined with late changes to yesterday’s plan, we came into today’s plan with 5% less power than expected. That’s a difference you likely never notice for your cell phone, but that was enough to drastically reduce our extra science time today. We managed to still fit in a ChemCam long-distance image mosaic, but otherwise are limited to our drill campaign activities where we will dump the remaining powdered rock in the drill onto the surface and conduct contact science on it with MAHLI and APXS.

Perseverance dropped the debris shield that protected the Mars Helicopter “Ingenuity” during landing!

We’re gettin’ there!

We needed scale! So Seán Doran added his ‘Pixel Percy’ to this mosaic of the delta [details and links in the comments]

  • The CGI rover is on the lower right of the delta in this mosaic of Mastcam-Z images from sol 26.

  • The rover is scaled to the correct size by Seán using NASA’s HiRISE DEM models of the terrain.

  • This is only a jpeg version of the image, his original PNG image would have been difficult to load here and would have been compressed. So here’s the link to the Flickr post where his original version is located. LINK – 5334 × 2496px

  • Seán has created a Flickr album for Pixel Percy, so we can expect more versions in the future.

Sound of Perseverance Mars Rover Driving – Sol 16 (1:30 minutes)

The audio Is taken from the 16 minutes long file, and cut in the same part as the 90 seconds one. So same audio but no noise reduction

“Perseverance’s engineering team continues to evaluate the source of the scratching noise, which may either be electromagnetic interference from one of the rover’s electronics boxes or interactions between the rover mobility system and the Martian surface” You can check everything

No problem 🙂 In any case you can check nasa website to keep yourself informerd on all the cool stuff perseverance does

I have 3 theories:

  1. electrical interference. I want to compare the screeching with motor current draw and see if there’s a correlation (but I need to find the time!)

  2. high-frequency acoustics conducted through the structure (this will be nearly impossible to determine)

  3. friction in the port bogie pivot. The microphone is mounted on a cable support doohickey due-aft of the port bogie pivot, aimed directly at the pivot. We could be hearing the internal workings of that joint. I don’t think this is the case because we hear the screeching immediately when motion starts and telemetry shows no motion of the suspension. But again, I’d like to overlay the acoustics with telemetry to look for correlations.

One thing that would be cool would be to look at this data in the frequency domain. I wonder if the audio is at a frequency that’s a natural mode of the structure. Any audiophiles out there want to make an FFT of this audio?

It would be nice to show a sound/video recording of Perseverence on Earth to see what’s different and stuff..

This is something that we’ve always wanted to do, but we do not have the EDLCam hardware installed on Optimism nor did we test this in ATLO due to scheduling constraints. I want to see if we can get it installed for a temporary test (think electronics zip-tied to the top of the chassis), to get a comparative data set, but I don’t think that’s in the cards for quite some time. That rover has a schedule worse than an overachieving kid with a helicopter-mom.

Are you really in perseverance team? I don’t know who trust, but you look real

Yes. I’m the lead mobility systems engineer. I helped sequence this drive and recording. I don’t have any good “proof” since we are all still work from home.

Awesome!

That creaking, though…

Members of the projects will lay out the steps necessary before the helicopter attempts its historic test flights.

NASA will hold a virtual media briefing at 1:30 p.m. EDT (10:30 a.m. PDT) Tuesday, March 23, to discuss upcoming activities for the agency’s Ingenuity Mars helicopter. The teams operating Ingenuity and NASA’s Mars 2020 Perseverance rover have chosen the flight zone where the helicopter will attempt the first powered, controlled flights on another planet.

The briefing will air live on NASA Television, the NASA app, and the agency’s website and will livestream on multiple agency social media platforms, including the YouTube and Facebook channels for NASA’s Jet Propulsion Laboratory in Southern California.

Briefing participants include:

  • Lori Glaze, director of NASA’s Planetary Science Division, NASA Headquarters
  • Bobby Braun, director for planetary science, JPL
  • J. (Bob) Balaram, Ingenuity chief engineer, JPL
  • Håvard Grip, Ingenuity chief pilot, JPL
  • Farah Alibay, Perseverance integration lead for Ingenuity, JPL
