<egg|zzz|egg> UmbralRaptor: but I don't get it, INTEGRAL was launched in 2002 and the book is from 2012
<egg|zzz|egg> did they change phasing?!
<UmbralRaptor> I don't know (sorry)

<egg|zzz|egg> that's definitely not 9

<UmbralRaptor> But that could be fun!
<egg|zzz|egg> UmbralRaptor: do we
<egg|zzz|egg> UmbralRaptor: or would it be Fun
<UmbralRaptor> Probably the later if in any detail
<UmbralRaptor> But, we're doing PI simulator for the design phase (sort of)
<UmbralRaptor> Aerospace subcontractor simulator?
<B787_300> sounds riveting
<UmbralRaptor> Braze yourself for the construction details
<UmbralRaptor> "What came to my mind about SIRTF was this high-Earth orbit. The project was happy with the way it was, but I knew that a simple calculation says that high-Earth orbit was not a very good orbit to be in from an energy perspective. But if I let SIRTF escape, I can actually use a smaller rocket; I mean, that calculation is very simple. But the thing I didn’t have time to figure out was, Which way do I send it [into solar o
<B787_300> egg|zzz|egg: i love that video
<UmbralRaptor> No, the book doesn't seem to give the HEO's parameters
<B787_300> What was SIRTF?
<B787_300> SIRTF?
<galois> SIRTF: Space InfraRed Telescope Facility (became Spitzer)
<B787_300> ah
<UmbralRaptor> I think before the 1980 decadal report the S was for Shuttle
<egg|zzz|egg> Spattle
<egg|zzz|egg> Spatula
<UmbralRaptor> Spatula Improved Rice Tasty Food
<B787_300> UmbralRaptor: before 86?
<UmbralRaptor> Uh, possibly
<UmbralRaptor> but I think the switch to free-flying was before that
<UmbralRaptor> Not sure at what point they gave up on shuttle launched
<B787_300> 86 would be a decent bet... because you know a big issue happened that year with Shuttle
<B787_300> egg|zzz|egg: random question have you ever seen the missile guidance video with the line "the missile knows where it is at all times. It knows this because it knows where it isnt"?
<egg|zzz|egg> yes

<B787_300> Just dont dream... or dont remember your dreams...
<B787_300> I havent had a dream I remember in quite a while
<egg|zzz|egg> UmbralRaptor: > You can probably make x-ray, particle, and magnetic detectors interesting (though this risks going over to being probes) << any specifics?
<UmbralRaptor> Chandra's orbit is in part to have it be above the van Allen belts, right?
<egg|zzz|egg> aaah right there's that too
<egg|zzz|egg> hm
<egg|zzz|egg> UmbralRaptor: yeah and then i suppose one should model the fact that observation should stop when entering them

<SnoopJeDi> UmbralRaptop, but the MU69 paper!
<UmbralRaptop> (I should have known that those low mass planet recoveries were too good to be true)
<UmbralRaptop> SnoopJeDi: link?
<SnoopJeDi> tl;dr "yay evidence for pebble accretion, dunno about the rest yet"
<UmbralRaptop> thanks
<SnoopJeDi> (it was today's happy hour link)
<SnoopJeDi> You're welcome! I'm delighted to share it with someone who actually astronomys for a living
<SnoopJeDi> Would love to do a Twitter thread about it, but if I do anything in the next few days it's for sure going to be about world metrology day and the death of Le Grande K
<SnoopJeDi> UmbralRaptop, I would love to hear your digest of that paper, btw, since you actually grok starstuff :)
