Your boss doesn't understand the concept of asynchronous communication -- annoying enough in normal email, but now you're on Laythe... Perhaps you should have double checked your staging first.
<Eddi|zuHause>
is it suggesting i should have ditched the boss during staging?
<Althego>
hehe
<raptop>
I think this means that due to a communications error, there was a staging error and now you're stranded on laythe
<raptop>
...or in orbit

You state that a plan to shoot a laser at the asteroid is like “shooting a b.b. gun at a freight train.” You exceed kmath's flood limit.
<packbart>
A stream of pellets will eventually erode the rock
<darsie>
And/or increase the asteroid's mass.
<darsie>
Shooting an asteroid with a laser will increase it's mass temporarily.
<darsie>
its*
<NGC3982>
how?
<Althego>
or it will decrease it by evaporating a part of the asteroid

<NGC3982>
energy divided by the speed of light times two?
<darsie>
Yes. Derives from E=mcc
<darsie>
no, squared, not times 2.
<NGC3982>
ah, so illuminating something effectively adds mass to it?
<darsie>
If it absorbs teh light, yes.
<NGC3982>
that's exciting
<darsie>
:)
<Mat2ch>
it really is exciting the molecules...
<NGC3982>
it seems rather counter intuitive
<darsie>
Raditing the heat away reduces mass.
<NGC3982>
but that seems to be the math so why not
<packbart>
it's a bit virtual, too
<Mat2ch>
mass is virtual as well. Not what we all think
<Mat2ch>
we think of it being like lifting a stone or something
<darsie>
Shining light onto matter also imparts impulse. I've changed Jupiter's orbit several times with my green laser.
<Mat2ch>
but that's not mass...
<Althego>
lol
<Althego>
a tiny change
<darsie>
:)
<NGC3982>
but, in reality, would evaporating something actually decrease the mass in the long run? given how that particular paper that went viral described that it wouldnt really help to -nuke- asteroids since they would simply reform again, evaporating stuff from asteroids to reduce mass seems hard work
<packbart>
darsie: well, eventually all those probes on slingshot orbits are going to slow down even Jupiter!1
<NGC3982>
i guess you would need to transport the vapour away or convert it to radiation or something
<darsie>
packbart: Not eventually. They do so every time.
<darsie>
NGC3982: If teh evaporated stuff leaves the asteroid, the remnant is lighter, yes.
<NGC3982>
but it's in space and the asteroid has gravity
<darsie>
If someone shines a laser on Earth, evaporating some water, Earth gains mass due to the energy gained, assuming the water does not leave Earth.
<NGC3982>
evaporated stuff will either reform with the asteroid or will need to be transported away, right?
<darsie>
If Voyager shines radio waves on Earth, Earth gains mass.
<packbart>
is a vaguely asteroid-shaped cloud of rocks better or worse than one large rock?
<Mat2ch>
NGC3982: Depends on the energy
<Mat2ch>
if it reaches escape velocity, it's gone.
<NGC3982>
yes
<NGC3982>
"transported away"
<Mat2ch>
If not then it can enter orbit or will just fall back
<NGC3982>
what do you call the process where atoms turn into energy?
<Mat2ch>
the question is: How long will it take to get back
<NGC3982>
a part of evaporation is converting something into heat
Fluburtur has joined #KSPOfficial
<darsie>
packbart: For mining a rubble pile may be easier.
<NGC3982>
and heat is radiation and ..massless?
* NGC3982
is confusing himself
<Mat2ch>
I'd define evaporation differently.
<Mat2ch>
Making something so hot it turns into a gas
<darsie>
Heat is energy. Doesn't have to be radiation.
<Mat2ch>
the atoms are still there
<NGC3982>
ah
Revelator has joined #KSPOfficial
<darsie>
Heat can transfer from one thing to another. Or radiate through space.
<packbart>
binding energy is magic
<Mat2ch>
But redirecting asteroids will be most likely the solution. Discorver them early, send some controllable mass near it, let gravity do the redirect
<darsie>
That requires an ion drive. An impact is probably much easier.
<darsie>
ISRU ion propulsion would be cool.
<darsie>
Like mining magnesium and pushing the asteroid around with it.
<packbart>
some molecules attract two other molecules at specific sites, a third at another, some energy bounces across and the two first molecules bind together while the third drops off some Phosphorus
<packbart>
ze mind boggles
<packbart>
enzymes are magic users
<darsie>
I write cc instead of c^2 because it's easier/faster.
<packbart>
well, there is a ²

windows-shift-6-2
<darsie>
cc
<darsie>
9.80665 m/ss
<darsie>
mm is ambigous
<darsie>
cc could be centi c.
<darsie>
10 cc :)
<darsie>
Instead of 0.1 c :)

well.

the Radeon Pro W4300 cannot run KSP with scatterer.
<Izzy>
it can run it without scatterer just fine though.

in addition, while doing so, it keeps your coffee warm!

Need to figure out how to unlock the settings on it so I can undervolt it, because it is toasty with stock settings.
