Marveling at the world

Lots of Martian rocks and landscapes, some looking all too familiar, but don't be fooled by that: Mars is an inhospitable toxic planet. Let's not mistake fiction for reality.

I like dirt and rocks, but I Am Not A Geologist (IANAG).

[O]ur online spaces are no longer open ecosystems. Instead “they’re plantations; highly concentrated and controlled environments, closer kin to the industrial farms that madden the creatures trapped within”.

"As we Irish discovered in the great famine of 1845-49, monocultures are generally not a good idea and we abandon biodiversity at our peril. […] the internet has become an extractive and fragile monoculture."

Earlier today, the rover captured this long distance view of the Mars Helicopter. The new image shows possible footprints from an earlier flight to the left of the current location.

Cool! ! Also seamless and leveled! 👍 !
Here is a slightly processed version of the same image showing features partly obscured by the orange haze, like a visor would probably show it to future colonists.

@stim3on
And here is a fake night-vision version of it, showing clearly even more features. The good thing is that your processing preserves all those details even if they are not prominent in your original. Makes me wonder about what optical filters future Mars Helicopter cameras might need to have in order to "see" better, and avoid problems like that which got Ingenuity disoriented and ended its mission. Although, of course, machine vision doesn't work the same as human vision.

at last turned its SUPERCAM telescope to . That's from a 500m distance. The smudge between the heli and its footprints on the left is dust or some other SUPERCAM flaw that exists in all images.

The glint from the metallic foot joint is noticeable.

Almost there. RMC 52.0870.

seems to be determined to reach Bright Angel as soon as possible, even if it has to do it in short drives every sol, through rocky ground.

If the does take an RTE picture every Martian morning as stated, then it will most probably capture the rover as it descends slowly the slope of Neretva riverbank. The only question then is when we will see those images.

Another drive from Perseverance rover takes it to site 52.0870 during Sol 1138 (May 3, 2024).

EDIT - The rover has not yet reached the downslope, see recent post by @65dBnoise

It's crossing the contours upwards, so it is still climbing. Its tilt is 8.66°, positive angle.

This one on Sol 1019 appears to have been another one where AutoNav had a hard time finding its way, but also had RIFMAX ops planned.

, a very accomplished POTUS who passed two Civil Rights Acts with bipartisan support, the Voting Rights Act, created Medicare and Medicaid, made 's program a priority, and had numerous other accomplishments, failed to change his mind about the Vietnam war amidst anti-war protests. He never got a second term, leaving the presidency to Richard Nixon

Much less accomplished Biden (see Anita Hill/C.Thomas) said student protests haven't made him rethink his policy in .

Too bad.

How is banning abortions and books different in political essence from helping kill children in a and forbidding by law criticism of it?

It won't be a clown who won a crucial election, it will be your colossal failure to persuade that Dems are different from those who brought the worst president in the US history to power.

When the economy is good and your opponent is in chaos, there's got to be something else you're doing that makes people distrust you.

New location for #Perseverance on Sol 1136, RMC 52.0606. If all goes smoothly, in two more similar drives the rover will be entering the field-of-view of #Ingenuity's RTE color camera, and Perseverance's team will have their last and only opportunity to have a picture of the rover captured from the ground of Mars, at least for the foreseeable future.

The map was made with #opensource #QGIS using #NASA's #opendata from #MMGIS #HiRISE and #USGS

@doug_ellison
Yes, but that doesn't say that transmissions ceased; it only says that Ingenuity's operations team is over.

After that last software update one would expect that the procedures about how to talk to the heli, now a stationary testbed collecting data, were handed over to the mission team, who already had procedures in place to communicate with it (img from the Analyst's Notebook).

If not them, who else could talk to the stationary testbed Ingenuity?

65dBnoise,
@65dBnoise@mastodon.social avatar

@doug_ellison
This is the part I'm refering to, wrt downlinking a few RTE images possibly showing the rover:

"With the software patch in place, Ingenuity will now wake up daily, activate its flight computers, and test the performance of its solar panel, batteries, and electronic equipment. In addition, the helicopter will take a picture of the surface with its color camera and collect temperature data from sensors placed throughout the rotorcraft."

This one appears to have been an overcurrent fault, at least on sol one of the 3-sols-circling-the-wagons operation. We don't really know if it did lay any eggs there. Who said that driving a rover on another planet was easy?
