Best way to habitate flipped asteroid?

[sheaker]

Dear All,

So it looks like my only source of niobium is somewhere here:

And I nee to reach it from to top. There is a space for rover or trailblazer module.

I am afraid that building 'door' tunnel would not be successful as magma is dense and has high viscosity. Then the pressure will probably crush the walls. So I guess I would need to drop water from above to cool down magma and dig it? Any better ideas? In fact this is not main problem...

How about landing itself? It is so hot that cobalt_ore rover already liquefied. I would need to land on it with trailblazer and rover modules made of steel, at the same time. Deconstruct both of them, then build rocket pad, land quickly another rocket... Is it even possible? Any tips?
Thank you!

EDIT:
Sorry guys, that is for sure Spaced Out content. I was reviewing both forums and unintentionally posted in on wrong one. Please, move if possible.

Escher pump(s) (make the magma fall through 2 different trapped gas cells) into infinite storage (walls made with steel airlocks)?

Yeah, I forgot about airflow tiles.

The simplest option is to use pitcher pumps to dump it to space.  Pitcher pumps won't overheat as long as it is only the stem that is in the magma.  Then set up some bottle emptiers on the obsidian and start dumping it to space.  There are more elaborate methods, but the basic approach is to send down 2 trailblazers, deconstruct them to build a rocket platform, and then have your dupes work from out of the rocket to get rid of the magma.  Rovers aren't very useful here.

Thanks. So it is aligned with what I was imagining. Pumping some of the magma into space via pitcher will be usefull here. Thanks!

My last visit here is almost the same as yours. Magma exposed to surface and boiled all my pre-supply petroleum interplanetary payloads. I have to setup the beacon and resupply them return fuel. Usually when I land on a new asteroid I prefer building rooftop first due to radiation.

When digging down on this asteroid, I mostly use obsidian insulated tiles instead of steel mesh because they are plenty here. I tend to use local materials because I may not bring enough in one trip and I'm trying to use less interplanetary payloads as possible.

 

Btw, I remember this asteroid named superconductive. Flipped is another asteroid in moonlet style. Just a reminder.

I would go with steel doors and obsidian tiles or steel airflow tiles if you are afraid of pressure, but it's only 4 layers of magma that you actually need to build through. And it even divided by layers of obsidian, so it should be very easy and pretty quick.

FYI dupes can build doors through closed doors and tiles in diagonal. Also dupes uses doors as ladders. Don't see a problem here. Especially in late game, when you already have enough steel, atmosuits and rockets in which you can live at least few cycles.

I would say just dig straight down building doors, get the niobium and get out of there.

Ok thanks guys. I will do it. It will take some time but that is the point!

I bet it harder, but it's definitely faster than this

Landing and establishing a base on water asteroid for graphite mining.

Later I abandoned idea of having a base there... On second trip just mined enough graphite and left with no intention to return.

Lava: I have cooled one down using a solar-powered cooler before. Takes a while but is entirely doable and you do not need to get that much material there.

As to water, the last time I just put an infinite water storage at the bottom open to the water. That works pretty fast.

Wish me luck guys:

I'll try to take some screenshots.

[Gurgel]

Good luck! It is a nice challenge!

As an alternative, I have just crushed lava with steel-doors now (yesterday). Works well and dupes in exo-suits can stay non-scalded long enough to install this 3 or 4 tiles below the lava surface. You need to make sure to only have one open job (e.g. digging one tile) or they may stay in there too long, but that is it. And they can go in again pretty much a few seconds later. I think I have completely lost my fear of lava now

This is a screenshot showing the mostly  correct tunneling method I use. The doors need to be rotated to be up-down doors though so dupes can use them as ladders. You also need to set a very high priority for the insulated obsidian tiles so that they're always built first.

Thanks Guys!

I am doing it without atmosuits. I had my doors set up horizontally - it was a mistake. I took not enough algae for oxygen production. I managed to gather like 120 Niobium and I explored asteroid a little bit. I found 2 or 3 terrestrial (hopefully) artefacts! But I run out of O2.

I just need to start from beginning and take more algae with me. Proceeding now!

 

EDIT:
I failed getting artefacts as they are deep and covered in hot (1500+) CO2. I didn't had atmo suits with me. However, 600kg of Niobium and two happy duplicants are going home safely. Rocket platform is built so I hope I will be back soon.

That is a neat trick! Does the lava in the path down get crushed when doing it this way?

I am impressed you managed without atmo suits at all. Quite an accomplishment I think.

PROTIP: Scalding damage is only from hot gas/liquid sharing a tile with the dupe.

Dupe shoes are made from neutronium.

If you had enough radiation or uranium, you could have used launchers to send the algae over. Or even water, since terrariums+pwater offgassing would be more mass-efficient here.

The case was they just did not fill the storage. I had to reload and give them another cycle to load stuff.

I was managing doors permission preventing dupes from going back to rocket for breath. I was pushing them to the limits. It was cruelty but we had to do it. As exchange they will be highly awarded.
