ScienceAlert posted:In this case, the glitch is coming from a disruption in communication between one of three computers onboard, called the probe's flight data system (FDS), and one of the probe's subsystems: the telemetry modulation unit (TMU). The Soviets just used hamster wheels Although I suppose hamster feed for 50 years would weigh more than an atomic pile, or at least go bad sooner. And what if the hamsters eat their young en-route? Tsk.

quote:Beyond the Oort Cloud, on the distant edges of the Kuiper Belt, both probes will inevitably fall silent as the power of their generators run out of juice. Isn’t the Kuiper Belt like light years closer to the sun than the Oort Cloud? There’s no way we’re still getting Voyager data in a thousand years or whenever that thing hits the Oort Cloud.

The NASA website says it'll take Voyager 1 about 300 years to reach our side of the Oort cloud, and I'm not about to check their math. NASA posted:The inner edge of the Oort Cloud, however, is thought to be located between 2,000 and 5,000 AU from the Sun, with the outer edge being located somewhere between 10,000 and 100,000 AU from the Sun. I don't think Voyager will have juice left then, hamsters or no. But on the positive side, there won't be radio telescopes on a burning Earth either to receive any space messages

(At 3 light years, you'd be deep inside the Oort Cloud of Alpha Centauri, though it's fun to imagine Alpha Centaurians invading because they mapped their own Oort Cloud so extensively they're now claiming Earth belongs to them since occasionally comets from their OC smashed into our planet.)

God imagine the tedious interstellar politics of the future - it’s all property line disputes over where whose Oort Cloud ends where like neighbors disagreeing over the placement of a fence or tree.

A rogue planet passes through the oort cloud right on the divider line between Sol and AC. The ensuing property claims dispute kicks off a 20 millennia long total war blood feud, laying waste to both systems. All orbital bodies have been reduced to a size no larger than an asteroid.

I like when space test don't kill adorable pets! Also that sounds like it could be really useful. I remember looking up the bandwidth we have available communicating with Mars and telescopes space ways and stuff, and yeah it's really not all that much, which for some stuff can be really limiting. Like for the James Webb Telescope, it seems like the speed it can send information is actually a bit of a limiting factor in how much it can be utilized.

https://en.m.wikipedia.org/wiki/Space_sexologyquote:Dubé and colleagues (2021) proposed that technological systems and guidelines enabling intimacy and sexuality in the limiting artificial ecosystems of space will need to be created.[1] They describe that these systems and guidelines will likely need to be designed to be both safe and hygienic, similar to the already established systems in place for other basic needs such as eating and grooming.[1] They also suggest that this challenge can be addressed by space organizations by considering the use of sexual technology adapted for space to meet the intimate needs of their astronauts, such as erotic stimuli, sex toys, and artificial erotic agents (e.g., virtual partners, erotic chatbots, and sex robots).[1]

Another Moon mission launched today:The Guardian posted:The Peregrine 1 lander carrying Nasa scientific equipment is on its way to the moon after a successful launch of the Vulcan Centaur rocket at Cape Canaveral. It marks the first launch of the powerful new rocket built by the Boeing-Lockheed venture United Launch Alliance, and an attempt to make the first US lunar soft landing in 50 years. Built by the space robotics firm Astrobotic, the Peregrine lunar lander launched at 7.18 GMT, aiming to become the first lunar landing by a private firm – a feat that has proved elusive in recent years. The tiny rovers sound adorable, but do we really need bitcoin in space?

Even if the buttcoin "coin" is just a dime-sized aluminum disc, I object to it on the grounds of it being trash. Rubbish. Literal garbage just strewn on the Moon for funsies by some of the most worthless morons humanity has produced. Sending a golden disc with nude people on is at least a symbol of reaching out.

It's gonna be trash anyway, now:  But I get why they did it. If you can get some extra funding for your space science fair project by selling what would otherwise be empty space to some morons so they can put their little token on the moon, why not?

I understand that we live in the Bad Timeline since Marty and Doc didn't assassinate Ronald when he was a GE propaganda man, but it's the principle of the thing. As much as I'd rather sub-Lunar space not be turned into an eternal robotic battle-ground à la Lem's dystopias, I'd also prefer some random billionaire doesn't fund a space program with the caveat they carve Hitler's face on the Moon as a sideproject or what have you. Of course the cynical response to the realist view is to say you shipped the buttcoin coin up there, but really didn't. What are the coiners going to do, go up there to check?

Heck Yes! Loam! posted:Mars is cold and thicc around the middle *Mars' axial tilt variation is massive and mathematically chaotic. IIRC, obliquity before about 15 Mya is basically impossible to know. Here's a Mars glacier (perspective generated from HiRISE) where you can see a lobe spreading out, complete with a terminal moraine:  c.f. a glacier in a similar situation in the McMurdo Dry Valleys:  https://www.antarcticglaciers.org/glacial-geology/glaciers-on-other-planets/types-of-glaciers-on-mars/

cat botherer posted:The article briefly mentions it, but Mars has glaciers remaining from the periods of high obliquity*, mostly on mountains at low/mid latitude. They really look like frozen-to-the-bed polar glaciers on Earth. Previously, they were thought to be pretty much all rock glaciers with just interstitial ice. However, some are probably mostly pure ice with a debris and/or salt cover (some people call those rock glaciers too, but they're pretty different than the interstitial ice kind). extremely dope thanks
