Confirmed. Hubble is moving to one gyro mode.

Some planets are born alone, live alone, and die alone. The ESA's Euclid space telescope just found a nest of these loners in the constellation Orion.

At least the rogue planets have chosen a gorgeous spot to go about their business: This is where the newfound worlds are hanging out (toward the top of the image).

Oh there you are!

The circle marks the location of a newborn free-floating planet (aka "rogue planet") wandering near the Horsehead Nebula.

@skrishna Does that leave the door open for further down the line, or do they mean they're planning on sunsetting Hubble entirely?

: Some of the incredible solar activity was captured last month by spacecraft near the Sun, including these plasma tornadoes. These walls of plasma are higher than the Earth is in diameter. And, of course, all this solar activity has provided us with stunning aurorae. With solar maximum approaching, chances are high that we'll see more incredible views like this one! Credit: NASA

@65dBnoise my favourites for tosol are the navcam panoramas, maybe it's the horizon distortion but it's such a different feeling to see the height difference between the channel and the upper fan from this side... Once again, what a hundred meters do to one's perception 🤯

Fewer rocks and an even ground may be enhancing (or even, creating) that feeling. After all, we're all soft tissued humans.

That was fast! After a couple of days of taking samples and taking selfies, China's Chang'e-6 probe lifted off from the moon's far side and is due to rendezvous with an orbiter to stash those samples for the trip back to Earth. https://cosmiclog.com/2024/06/04/chinese-probe-collects-moon-samples-and-lifts-off/ #Space #ChangE6 #China #Moon

In other news, because there isn’t enough going on this week: is Hubble transitioning to one gyro mode??

WammKD,

@skrishna

I dunno if it helps but just adding some (possible) context: I notice he's from Chicago and that's sort of a meme, around here (I assume due to the number of Greek restaurants around). You never (that I noticed, at least; I could be wrong) actually pronounce it (as the article's just text) so I think he was just making a joke.

Speaking of the article, it was a really interesting! It definitely makes sense but I'd never even thought about upkeep for the Hubble.

skrishna,
@skrishna@wandering.shop avatar

@WammKD Very possible he was making a joke, but I have never interacted with him and I'm at the point where I'm not giving anyone the benefit of the doubt on here.

The odds are better for a Martian Crow to flyby the heli and say "caw-caw" than they are for the rover to cross the sand field and say "cling-cling" 🥴

PaulHammond51,
@PaulHammond51@fosstodon.org avatar

@65dBnoise I'd have to agree with those odds. I can imagine some of the engineering team that built it would give limbs to get a closer look...

Quick astronomy question - what sort of surface ices are plausible for a Sednoid 550AU from the Sun?

For an SF story setting, I'm using a Sednoid binary system similar to a scaled down Pluto-Charon system.

Effective temperature around 10K, but I think this is still too warm for hydrogen ice.

I am aware of water ice, CO2, carbon monoxide, nitrogen, methane, ammonia, suflur dioxide ... anything I'm missing or stuff I should discard?

Thanks!

isaackuo,
@isaackuo@spacey.space avatar

So, the Sednoid's largest moon will be around 100km radius, non-spherical. My two basic models are Neptune's moon Larissa and Saturn's moon Phoebe (possibly captured from further away - the Kuiper Belt).

I don't know how different to expect a similarly sized object would be in a Sednoid orbit. Should the surface composition be mostly water ice and silicate rocks? Or would a Sednoid have more of other ices like CO, CO2, N2, CH4?

https://en.wikipedia.org/wiki/Larissa_(moon)
https://en.wikipedia.org/wiki/Phoebe_(moon)

Phoebe, a moon of Saturn

isaackuo,
@isaackuo@spacey.space avatar

The Sednoid itself could be similar to Triton (thought to be a capture KBO like Phoebe), but much smaller (about Enceladus sized).

Though Triton's crust is thought to be mostly water ice, a majority of the surface is covered by nitrogen ice, and some CO2 ice.

A thick layer of nitrogen ice, in particular, could be a problem for Cutty trying to get at useful resources to sustain her life support systems.

Busy week for space stuff!

  • Boeing Starliner launch: June 5, 10:52 am ET
  • Starship IFT-4: June 6, 7 am CT (pending launch license)
  • Chang’e-6 landed on the far side of the moon 6/1, will launch early this week with samples
  • huge sunspots pointed at Earth

@skrishna it's still confusing, especially when you write out the month for the other dates in the post.

@skribe I dashed a quick post off while I was making my to do list for the week in an effort to be helpful to others for free. Sorry it wasn't good enough for you!

It looks like #Perseverance went for the bacon¹ 🙂

On Sol 1168 the rover moved to RMC 52.5032 across the ancient riverbed and stopped a few meters away from a light colored layer of rock at the foot of the northern bank, which appears to be the same layer with that of Bright Angel.

¹"the bacon strip": unofficial name for a light colored layer of rock back at the Three Forks area.

@PaulHammond51

The HiRISE/USGS imagery has been imported into QGIS and since forgotten. I'm not fiddling with the rest of the imagery any more, though I used to do that earlier in this mission.

"Space economy" seems to have real impact on the way NASA engages with the public. I've spent a lot of time creating workflows with their data, e.g. for the #MarsWeather reports, LA, etc, but they're now discontinuing services while the mission is still active. That's not very encouraging.

PaulHammond51,
@PaulHammond51@fosstodon.org avatar

@65dBnoise I think we've all seen the decline in the timelines of the release of new data, and in some cases the complete loss of some data with the move to the new style web pages. Not encouraging at all. It's a sad state of affairs. I did use the on-line feedback form to complain, but I feel that was just shouting into a vacuum
