Are those… Philips screws? Looks like maybe two dots indicating JIS (shallower angle, less cam-out, and #1 cause of stripped screws on Japanese motorcycles) but I’d really like to know why a hex or torx screw wasn’t used
I was curious about that too. They look like Torq-set to me, being that the slots are offset from the center of the screw. If that’s the case they’re shouldn’t be any cam out at all.
In either case the fasteners that were stuck appear to be Hex head, and the phillips looking fasteners just held a protective cover in place (?)
I would imagine NASA would know better than to use Philips for anything lol.
By the way there is a link on the page to more images of the assembly
Barnard b [2], as the newly discovered exoplanet is called, is twenty times closer to Barnard’s star than Mercury is to the Sun. It orbits its star in 3.15 Earth days and has a surface temperature around 125 °C. “Barnard b is one of the lowest-mass exoplanets known and one of the few known with a mass less than that of Earth. But the planet is too close to the host star, closer than the habitable zone,” explains González Hernández. “Even if the star is about 2500 degrees cooler than our Sun, it is too hot there to maintain liquid water on the surface.”
Mathematically, it’s possible, but scientists are still skeptical about whether or not they are real. They’re called white holes and you can actually create a model of one in your kitchen sink. If you let the water just hit the bottom and spread out evenly in all directions, you can kind of visualize the way it’s supposed to work. Action Lab on YouTube actually has a pretty good video about it which I suggest watching if you’re interested. youtu.be/p3P4iKb24Ng?si=b3_RHuj0J3F_7DC1
Tangent, but you don’t need to include the question mark or anything after in most urls. Definitely not YouTube links. It’s just YouTube telling itself who shared the info (you) and they use that to track shit. But the link works just as well without it, and you’re not voluntary spying on yourself.
I have not heard a car for a few hours. Not even the rumble of traffic in the distance and I can see the night sky without light pollution. It is a very privileged experience in some ways and while it has its advantages we are measurably disadvantaged in most human development metrics: health, education, income etc compared to people living in urban areas of our own country. The disadvantage is real and pops up everywhere from cancer survivability to suicide rates. Equitable internet access is more important than many people appreciate. If we can improve services to everyone AND protect radio astronomy that is a worthy goal.
How does fiber being cheap help them if no ISP is willing to dig miles and miles of trenches to lay it and connect to their home? I live in the middle of suburbia and don’t have access to fiber.
Your comment about subsidizing their lifestyle doesn’t really make sense. What are you subsidizing exactly? This tech is also useful in poorer countries that don’t have the infrastructure at all.
Any chance the Starlink satellites could be built to double as a sort of large-array telescope themselves, to compensate for the ground-based interference?
What’s more likely to happen is Starship’s will be launched where the entire ship becomes the telescope, and then we’ll have arrays of these much further away.
Not sure if it’s the same for radio, but for optical that means we can get a 9 meter mirror up there without any expensive folding mechanism, and who knows how big if we fold them as the fairing is not only wider but also longer.
Cost would go from billions to hundreds of millions or less. James Webb cost 10b.
The James Webb folding mirror is 6.5m and was folded into a 4.5m fairing…
From my brief look into the topic, interferometry tech is not quite there yet, but might be in the next few decades. Interferometry is more difficult with shorter wavelengths.
Neatly showing off how our moon is exceptionally dull. Here we are, the only dot in the sunbeam that’s not black or white, and our sole natural satellite is this flat dark powder-gray.
And it’s tide-locked! We don’t even get to see all of it. Imagine if Mars had its twin enormous boulders, and they always looked like cardboard cut-outs. Thank goodness for all this water and life and crap, or we’d be a C-tier heavenly body.
Since October 2023, the rover has been exploring a region of Mars rich with sulfates, a kind of salt that contains sulfur and forms as water evaporates. But where past detections have been of sulfur-based minerals — in other words, a mix of sulfur and other materials — the rock Curiosity recently cracked open is made of elemental, or pure, sulfur. It isn’t clear what relationship, if any, the elemental sulfur has to other sulfur-based minerals in the area.
