L55[08:37:40] <Mat2ch> Althego: no hop? :(

L56[08:39:36] <Althego> there is a brief closure

L57[08:39:45] <Althego> but looks like it is really tomorrow

L58[08:40:32] <Mat2ch> oh, wow, it took ESA 7 years to figure out that Ariane 6 is not competetive.

L59[08:40:46] <Althego> sunken cost falalcy

L60[08:40:49] <Althego> they cant stop now

L61[08:40:53] <Mat2ch> At this speed we will see a reusable cheap vehicle in, uhm, 2050 or so.

L62[08:43:27] <Mat2ch> I wonder if Scott Manley will make a video about it. :D

L63[08:43:47] <Althego> heh there was a video yesterday

L64[08:43:57] <Althego> and i didnt say it

L65[09:06:31] <Mat2ch> Althego: how do you know that the hop is not today?

L66[09:06:48] <Althego> because it moved on the sites to wednesday?

L67[09:07:10] <Althego> or rather on nextrocket

L68[09:07:18] <Althego> rocketlaunch doesnt show it

L69[09:07:30] <Althego> at least not for any specific day

L70[09:07:36] <Mat2ch> and where does nextrocket get that information from?

L71[09:07:53] <Althego> i dont know. "not always right"

L72[09:08:00] <Mat2ch> the road closure is still scheduled, the tfr still active and apparently some workers attached cameras to the top of SN11

L73[09:08:13] ⇦ Quits: hnOsmium0001 (uid453710@id-453710.stonehaven.irccloud.com) (Quit: Connection closed for inactivity)

L74[09:08:28] <Althego> just a brief closure

L75[09:08:36] <Althego> maybe moving a crane

L76[09:09:52] <Mat2ch> hm, ok, yes, that is odd.

L77[09:10:08] <Mat2ch> but why should they move the crane before the flight?!

L78[09:10:34] <Althego> unless they want to move something out of the launch site

L79[09:10:44] <Althego> i think tankzilla is not there at the moment

L80[09:11:37] <Althego> so we can only wait and see

L81[09:13:39] <Althego> or they trick everybody and prepare and launch and recover it in one hour :)

L82[09:15:22] <Althego> another thunderf00t video. i actually like jixuan and sebastian. but even i noticed that there were problems with the hyperloop. and i still dont believe it to be a useful idea at all

L83[09:16:00] <Mat2ch> Prepare and launch in under one hour would make some ESA engineers shiver in fear of their job.

L84[09:18:24] <Althego> and i think it is impossible

L85[09:18:35] <Althego> just because you cant fuel the cryogenic liquids that fast

L87[09:39:43] <Mat2ch> yeah, then it's probably only the crane

L88[09:40:00] <Mat2ch> maybe they move it to the landing site to be able to recover SN11

L89[09:40:09] <Althego> maybe they move the booster there just to test the movement process

L90[09:40:35] <Althego> eh dst coming up this sunday

L117[12:30:19] <Althego> so elon wants to land a starship on mars before 2030

L118[12:30:25] <Althego> possible

L119[12:30:48] <Althego> control through the dsn?

L120[12:31:11] <Althego> or maybe special long distance starlinks?

L121[12:46:07] <Mat2ch> fully autonomous...

L122[12:47:15] <Althego> cant

L123[12:47:21] <Althego> you need course corrections

L124[12:47:23] <Mat2ch> AI!

L125[12:47:49] <Althego> actually, supposedly with quasars you can do extremely precise location in the solar system

L126[12:48:09] <Althego> where did i hear this from, maybe anton petrov

L127[12:48:34] <Mat2ch> well, I read about it

L128[12:48:38] <Mat2ch> star trackers use that

L129[12:48:55] <Althego> so maybe as of this year it is possible to do it autonomously

L130[12:49:01] <Althego> but that is not very exciting

L131[12:49:12] <Althego> it goes there and comes back on its own

L132[12:49:20] <Althego> dont see it for 2 years ofr so

L133[12:49:36] <Althego> so normally you would expect some sort of communication

L134[12:52:54] <Mat2ch> there will be some sort of communication

L135[13:01:59] <Althego> and so we arrive back to the question, if it going to be the dsn or elon comes up with something new again

L136[13:03:59] <Mat2ch> DSN, since it's only a few packages.

L137[13:06:47] <Althego> for the first settlement maybe it should do a reverse dsn. build the dishes there and have a local satellite network

L139[13:14:46] <Mat2ch> And then... LASERS!

L140[13:14:56] <Althego> ah yes, lasers can do anything

L141[13:15:13] <darsie> How would we figure out the course corrections? Telescopes? Can SS do that?

L142[13:15:30] <Althego> btw yes, i am waiting for real use of laser communications for interplanetary desitances

L143[13:15:36] <Althego> distances

L144[13:16:33] <darsie> What lasers would we use? Ruby? CO2? q-switching?

L145[13:16:55] <darsie> With mirrors?

L146[13:17:04] <darsie> With parabolic mirrors?

L147[13:18:44] <darsie> Or are the cavity mirrors and medium surfaces good and large enough?

L200[18:04:13] <packbart> it might have popped a tank, maybe. "There was no indication of collision as the cause of the break up" https://en.wikipedia.org/wiki/NOAA-17#Mission

L201[18:14:01] <Mat2ch> It's getting time to cleanup this planet and the space surrounding it.

L202[18:15:55] <Althego> going to clean up in a few hundred years

L203[18:16:02] <Althego> one way or another

L204[18:17:05] <Mat2ch> I'm talking about now...

L205[18:17:22] <Mat2ch> and while we're at it we should clean up the atmosphere as well.

L206[18:18:06] <Althego> atmoplane :)

L211[21:11:43] <flayer> well, my eve mission was a disaster

L212[21:11:58] <flayer> didn't land on gilly, and got a rover stuck in a suborbital trajectory without comms

L213[21:17:26] <flayer> maybe i can salvage it when we get closer to kerbin

L216[21:37:23] <darsie> How does a rover get stuck in a suborbital trajectory?

L217[21:38:09] <raptop> Given gilly's infamous lack of gravity, driving too fast?

L218[21:39:43] <darsie> It should come down eventually.

L219[21:40:45] <darsie> I never put a rover on Gilly. Did a few ion ships, and refuelled my Eve missions there.

L220[21:40:45] <flayer> nah, i'm just not proceeding with the aerobraking and left the scene when it was on its apoapsis

L221[21:41:14] <darsie> Lithobraking. There's no air on Gilly.

L222[21:41:24] <flayer> orbit around eve

L223[21:41:37] <flayer> i didn't land on gilly

L224[21:41:51] <flayer> i could've landed on gilly, gotten all the science, but i was like 'na the primary mission is the rover'

L225[21:43:15] <raptop> Is it really a landing, or more of a docking?

L226[21:43:50] <darsie> You land on Gilly. It doesn't have docking ports.

L227[21:44:42] <darsie> If wheels had angular momentum, I guess rovers could right themselves after falling over on Gilly.

L228[22:00:41] <Izaya> External reaction wheels.
