Editing Talk:1992: SafetySat

<!--Please sign your posts with ~~~~ and don't delete this text. New comments should be added at the bottom.-->

I was excited that I might be the first to give an explanation (because the comic was so late in being posted), but when it finally arrived, I had no way to interpret it.  It was just a gigantic Γ shape (though with a rounded corner). Now that the real comic{{Citation needed}} has been posted, I find that I'm ''still'' not very qualified to explain it.  (I can guess at some of the references, but not the important ones.) I guess my only constructive comment here is encouragement to have a section (trivia?) talking about the initial failed comic image.

:There was a broken image a xkcd and uploaded by the BOT. It's now fixed at xkcd and here too. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 19:48, 11 May 2018 (UTC)

Someone should point out how much damage the "extends spikes in all directions" safety measure could do. And I note SpaceX scrubbed a satellite launch with 1 minute to go yesterday because of some anomaly. Maybe the impetus for this cartoon?

I figured today's comic was in reference to this picosat launch from India, which was denied launch in the US for being below minimum size ("too hard to track if they go offline") & thus in violation of the requisite cubesat specs:

Personally I'm in favor of these sub-cubesat launches; My concern is with liability, not safety, per-se.

:I would be concerned with safety as well, if not for the radar reflector ... seriously, this looks more like FCC wanting to destroy the company for being innovative than trying to ensure the visibility. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 23:01, 11 May 2018 (UTC)

Considering that it says the solar panel was "found", I think that implies that perhaps it was stolen? Or just literally found on the side of the road. Either way, it seems kinda shady. [[User:Carrera|Carrera]] ([[User talk:Carrera|talk]]) 22:20, 11 May 2018 (UTC)

Are there any rules regarding solar panels on spacecraft? Seeing that Randall "found" it, I'm wondering if this would be a violation of any rules. [[User:Herobrine|Herobrine]] ([[User talk:Herobrine|talk]]) 23:41, 11 May 2018 (UTC)

What would happen to wet sand if put in a cubesat and then released?  Water released into space boils and then desublimates into a cloud of ice crystals.  But what would the temperature and pressure be as the cubesat was launched?  Starting from wet sand at one atmosphere and whatever ambient temperature, would it cool down fast enough for the water to freeze before it was dispensed? (Release a gritty snowball.) If the dispenser is not kept at atmospheric pressure, would the water boil as the satellite was ascending to orbit? I wish Randall was still doing what-if.

:I have no idea, but would imagine that water in sand would freeze the sand together into small clumps that could penetrate other satellites, rather than just evaporate. We must try this soon... (Kessler...) ;) --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 20:40, 13 May 2018 (UTC)
::In our solar system the {{w|Frost line (astrophysics)|ice line}} is inside the asteroid belt beyond Mars. This means water in Earths orbit exposed to the vacuum and the sun will evaporate. And the heat from the Sun is even high enough to trigger this very fast. More far away - e.g. at Jupiter - that wet sand would freeze to a dirty snowball. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 21:32, 13 May 2018 (UTC)

> quality of the solar panel and the power it produces<br>
Quality of the power ?  Isn't all solar power clean and green quality ? [[User:Spongebog|Spongebob]] ([[User talk:Spongebog|talk]]) 04:28, 12 May 2018 (UTC)
:Well a solar panel's efficiency depends on how well it's made, and what materials have been used to make it. Considering that it was just "found", it may not be efficient enough to actually run the satellite, or even work in a vacuum. Then again, it's not like the satellite does much other than point lasers and explode. [[User:Carrera|Carrera]] ([[User talk:Carrera|talk]]) 05:21, 12 May 2018 (UTC)

-I am totally surprised that nobody either commented on or included a mention in the explanation of the obvious misnomer of the title of the comic! Doesn't anyone else think this cubesat is the opposite of a SafetySat in every way possible, which I think is the main joke of the comic? I would update the explanation accordingly, but I'm not sure where exactly this point should be made. Anyone else want to take a crack at it?
