One of the most important ones that a lot of people use every day are the huge advancements that have been made in creating modern chips. It might not be something new and exciting, but it actually involves very groundbreaking work and huge breakthroughs. Not just the crazy machines that ASML makes, thought to be breaking the laws of physics just years ago. But also advancements in manufacturing, being able to create super advanced 3D structures and large scale manufacturing at a very high level, yet with a surprising consistency in quality and low cost. Not just for ever bigger, more efficient and faster chips, but also things like MEMS at tiny sizes and low cost.
Often it's taken for granted what we have. People saying stuff to the sentiment that this isn't the future, everything is boring, we haven't got flying cars or people living on Mars. But the fact we all got this ultra powerful computer, with a high resolution high framerate self emitting screen, no active cooling, a bunch of sensors, lots of memory and storage and hyper connected to all sorts of networks, all powered by a high capacity high power low wear battery should be mind blowing. And not just that, but it fits in our pockets and they are so cheap everyone has at least one. Just because we've chosen to spec our tech tree into the small stuff instead of the large stuff, doesn't mean we haven't come a long way.
I think people look at the past at new "inventions" and think that's the way progress is. New revolutionary stuff. It's why people often invest in crowd funding of obvious scam products. They want something that changes the game. In reality it's a lot of little steps that create a big change over time. And imho this has always been the case. We always hear about the Wright brothers "inventing" the airplane. Like they had some magic sauce and thought of something nobody else thought of before. Then made it and bam the world was changed. In reality they didn't invent anything, they developed it. They made prototypes and iterative refinements. And they were far from the only ones working on the exact same concept. If they didn't finish first, someone else would have within the same time frame. But the romantic story of two American blokes with the right stuff changing the world all on their own just sounds good.
So let's also celebrate the thousands of smaller breakthroughs that got us where we are today.
No, there isn't any atmosphere to keep in the water. If you heat up the ice, it will sublimate directly into gas. Since the gravity is so low, it will stream out and create a trail all around the orbit. The solar wind would blow it away from there.
There's more to having liquid water than just temperature, pressure is needed as well.
Also Ceres might be small for a planet/moon, but it's still huge. The amount of energy needed would also be huge. And without an atmosphere you'd also be losing a lot of energy due to it radiating out into space. I'm not a 100% sure, but I think Earth is actually an iceball from where it's located in the solar system. It's only due to the atmosphere it's mostly non frozen (and if we keep pumping the CO2 and methane like we are, in the near future it won't be frozen at all).
