  • I didn’t say it was impossible, I said it was hard. Bigger radiators absorb more heat when exposed to the sun. One of the problems becomes keeping the solar panels exposed to sunlight while keeping the radiators out of it. Putting them behind the solar panels might work, but they have to be smaller than the solar panels and any energy the solar panels don’t convert to electricity will be re-radiated as heat and picked up by the radiators, requiring a larger size. You could put them on the 'back" side of the spacecraft, but that limits the size. As mentioned in another comment, you could position the spacecraft in geostationary orbit on the terminator, but then reaction mass requirements for station keeping and data signal latency go way up. It’s a problem that has been worked around by people much smarter than me, but a lot of work went into figuring it out.


  • Space isn’t cold, it’s nothing. It’s a vacuum and vacuum is terrible at heat transfer by convection. It’s why thermos bottles have a vacuum layer to prevent heat transfer. You can try to lose some heat by radiant cooling, but that’s slow and if you’re using solar for power then any radiators become heat sinks picking up more heat from the sun. Then there’s conduction, and again, there’s really nowhere to conduct any heat to, what with the large distance between objects and the vacuum and all. Thermal management in space is kind of a hard problem.







  • Agreed.Also, Windows and OSX, unless you want to have to call your nephew who’s Good With Computers™ every couple of weeks. If you’re just using a browser for everything and never messing around like a good majority of people, Linux is just as good as either of those. Linux has gotten to the point where it’s Grandma proof if you stick to a distribution that prioritizes stability. If you choose a distro that prioritizes bleeding edge software versions, you may come across more bugs and breaking changes.Then you’ll need the troubleshooting skills mentioned here. Most of us are here to learn and mess around; the troubleshooting skills grow from that mindset.


  • I agree with your lack of affection for cloud services, but I think your view might be a little skewed here. Does a senior mechanic need to understand the physics of piston design to be a great mechanic, or just gather years of experience fixing problems with the whole system that makes up the car?

    I’m a Senior Systems engineer. I know very little about kernel programming or OS design, but i know how the packages and applications work together and where problems might arise in how they interact. Software Engineers might not know how or don’t want to spend time to set up the infrastructure to host their applications, so they rely on me to do it for them, or outsource my job to someone else’s computer.
