@Rotonen ...uh. "ice"
Clueless
2018-07-25 16:01:14
"ice" == "water" no?
Clueless
2018-07-25 16:01:16
:P
Clueless

most of the polar ice caps on mars are carbon dioxide
Rotonen
2018-07-25 16:02:06
and I thought I was so smart
Clueless
2018-07-25 16:02:21
it's cold out there

When I become dictator the terraform mars project will get going.
Fireduck
2018-07-25 16:38:11
Did you know reaching LEO is 95% of the energy needed to reach mars?
Fireduck
2018-07-25 16:38:26
Our ICBMs have more than a 5% margin, we can reach mars with them.
Fireduck
2018-07-25 16:38:40
Step 1) Nuke the shit out of mars, melt those caps and get things moving
Fireduck
2018-07-25 16:38:59
Step 2) Bombard with every bit of organic matter that we can, something will grow
Fireduck
2018-07-25 16:39:38
Doesn't matter what, as long as it gets a cycle going and starts getting more things happening in that howling nothing mars calls and atmosphere
Fireduck
2018-07-25 16:40:45
Not sure how to fix venus. Might need some sort of relativistic projectile the size of a city to break it into two planets that suck less
Fireduck
2018-07-25 17:01:28
I don't think the hard part is getting to mars. I think the hard part is surviving the trip.
Clueless
2018-07-25 17:01:59
Example. I read somewhere the trouble with launching humans is that you have to launch them *slowly* enough they don't internally liquify
Clueless
2018-07-25 17:04:35
humans come later
Fireduck
2018-07-25 17:04:41
nukes and bugs don't care
Fireduck
2018-07-25 17:52:57
ICBMs do not have upper stages and none of their stages are relightable
Rotonen
2018-07-25 17:53:14
otherwise you will have to do quite the hell of a darts throw to hit a planet
Rotonen
2018-07-25 17:58:32
they don't have a RCS?
Fireduck
2018-07-25 17:58:36
I am no expert
Fireduck
2018-07-25 18:00:05
iirc final adjustments are usually by reentry fins
Rotonen
2018-07-25 18:00:43
by individual warheads, at that, too
Rotonen
2018-07-25 18:02:31
fins won't get much on mars
Fireduck
2018-07-25 18:02:37
might need to retrofit
Fireduck
2018-07-25 18:05:38
if you even manage to hit the athmosphere to begin with
Rotonen
2018-07-25 18:05:54
right
Fireduck
2018-07-25 18:06:16
also will need to either completely redesign or have an entry burn to not slam into the feeble athmosphere and burn up from the pressure front
Rotonen
2018-07-25 18:06:50
heh, details
Fireduck
2018-07-25 18:07:00
when I am dictator I'll have some people look into it
Fireduck
2018-07-25 18:07:38
but on the topic, the inflatable spinning hypersonic deceleration stuff they're currently dreaming up and even testing is nifty

Rotonen
2018-07-25 18:08:51
a thin athmosphere is a bad deal, you get the worse aspects of both: no useful deceleration, massive heatup
Rotonen
2018-07-25 18:11:06
sweet
Fireduck
2018-07-25 18:11:34
and probably not enough density to actually dissipate any heat
Fireduck
2018-07-25 18:13:27
earthbound heat shields work by ablation, the hot stuff boils off and that's the thermostat
Rotonen
2018-07-25 18:14:14
don't recall what the issue with that was on mars, but they'd not go for complicated trickery if something tried and tested would work well
Rotonen
2018-07-25 18:35:43
@Fireduck seems you need a WORM solution

yeah that would be awesome
Fireduck
2018-07-25 18:37:09
160000*4096/1e6 = 655 MB/s random read
Fireduck
2018-07-25 18:37:10
kinda sucks
Fireduck
2018-07-25 18:38:09
I've still never personally run anything that beats my intel nvme 750
Fireduck
2018-07-25 18:38:12
that's essentially just metrified to max out SATA and optimize cost for that per capacity?
Rotonen
2018-07-25 18:38:16
which manages 1800MB/s on random reads
Fireduck
2018-07-25 18:38:41
yeah, but i somewhat doubt sustainably priced 8TB NVMe will be a thing anytime soon
Rotonen
2018-07-25 18:38:50
true
Fireduck
2018-07-25 18:39:02
you'll eventually need a *something* large, for which some entry level data centre SAS disk will do
Rotonen
2018-07-25 18:39:30
it is a strange can of worms that I've opened
Fireduck
2018-07-25 18:43:10
IO is also a happy litte sandbox for systems stuff for the foreseeable future
Rotonen
2018-07-25 18:43:23
compute is getting way too complex, heterogeny is coming quick
