the author of that video is apparently competing with another person from CN on a trajectory that flies by all planets

oh NICE. incl. inner system?

I suppose? "I use 4600m/s of dv and spend 31 years to achieve it, but he only use 3892dv and 23 years"
<egg|zzz|egg>
"and his dv of DSM is only 8m/s"

That's surprisingly way way less than I'dve eggspected

Trying to help a friend work out how best to find the centerline of the void in a fairly arbitrary 3D spiral shell. Does this look sane? https://i.imgur.com/90DqU3R.png

(I didn't draw the toy problem quite right to highlight that the most recent tangent needs updated, but this shows that a bit more: https://i.imgur.com/oLqqAVc.png)

It looks like under the keyword of "curve reconstruction" there are quite a few ways to go about this problem, unsurprisingly. Oh well, it was fun to brainstorm an unsophisticated way of doing it :)

15:44:43 < egg|work|egg> mofh: plenty of times when you want a range that doesn't start at 0
<mofh>
okay, I legitimately want to know when you'd want that, since I'm at a total loss when and why that would be useful.
<mofh>
(also Perl used to support doing eggsactly this, for what it's worth. iirc it was virtually never used and the manpage loudly and strongly told you to not use it).
<mofh>
also try redownloading that font, i think i fixed it so windows accepts it now.

UmbralRaptop: why are XMM-Newton and CXO in those strange eggscentric orbits
<egg|zzz|egg>
ah "The spacecraft spends 85% of its orbit above the belts of charged particles that surround the Earth. Uninterrupted observations as long as 55 hours are possible and the overall percentage of useful observing time is much greater than for the low Earth orbit of a few hundred kilometers used by most satellites."
<egg|zzz|egg>
and "XMM-Newton’s high-technology design uses over 170 wafer-thin cylindrical mirrors spread over three telescopes. Its orbit takes it almost a third of the way to the Moon, so that astronomers can enjoy long, uninterrupted views of celestial objects. [...]XMM-Newton’s highly eccentric orbit has been chosen so that its instruments can work outside the radiation belts surrounding the Earth."
<UmbralRaptop>
xray telescopes are weird

UmbralRaptop: ISO does the same thing though and that's infrared

also, that sat contracts page is making me think of how Hipparcos still worked despite the partial launch failure, and how Spitzer's orbit changed
<egg|zzz|egg>
UmbralRaptop: eggsactly
<UmbralRaptop>
(And, well, Herschel an JWST use completely different orbits)
<UmbralRaptop>
Solar observations, uh, there's L1, earth-trailing/leading, and I think a sat or 2 in LEO?
<egg|zzz|egg>
yeah crepuscular LEO

UmbralRaptop: basically the whole point is "contract for mission constraints, not orbits"
