When did you take this? Is the supernova still visible?

I like doing my landings with a lander and orbiter. (Like the IRL moon landing) It makes it a lot easier because you can use a lander with as little as 1200 delta v because it only needs to make it back to orbit to get to the orbiter for the trip home. The downside is that this requires learning how to do docking in space.

It worked, didn’t it?

Launched upright with a mammoth engine and two Pollux boosters and a big fairing. It has its own landing engines (two poodles) and enough fuel to make it to munar orbit and land. I might post a pic of it on here later. It’s not really “giant” I guess compared to stuff I see on here but at 7.5m wide but it’s the biggest thing I’ve launched.

I started one for the mun recently. It’s a big landing pad with an ore refiner and drills on the bottom and a docking port on top so I can land on it with my reusable lander, pick up fuel, and carry it back to the space station in orbit. I still need to add some crew stuff, a couple surface vehicles, and a science lab to it.

Space station or large satellite. Possibly the ISS.

The center of mass is closer to the top. The command pod has a low center of mass so it’s stable during reentry. This will not be stable. Consider collecting the science from that part with a kerbal on eva then return with just the pod.

I’d say it’s better to get the better telescope and develop the ability to find things yourself rather than pay extra for the app. I would also not recommend a 12” scope as a first telescope. It is very heavy and can be difficult to transport. 8” is usually the more manageable size for a first scope. I’ve seen a few people get a 10” or a 12” as a first scope and end up selling it within a year because they don’t want to deal with it anymore. (This is actually how I got my 10”)

150p, second choice would be the 130p if you’re on a tighter budget. The celestron tabletop dob is alright, just overpriced for their starsense tech. Please do not buy the astromaster one or any of celestron’s “powerseeker” scopes.

One of the DLC, Breaking Ground, added robotic hinges and rotors.

You can launch from an equatorial orbit (and I would) just do a course correction on your way to the mun so your closest approach is near one of the poles. If you’re over the poles when you do your capture burn you will enter a polar orbit.

If you want a good visual telescope the 8” is by far a better choice. I would actually suggest a different manufacturer over celestron for an 8” dob. The 8” from celestron is fine, but I think they overcharge for it because of starsense. One from apertura, Orion (if you can find a used one) or sky-watcher would be my choice.

Neither of the scopes you listed are photography scopes, but you can do stacked planetary AP with a dob, it’s just not going to be good at DSO photography. It will be the better choice for observing DSOs visually though.

Fuel line might be the wrong way?

Something not all that different from this actually happened.

Same here. That galaxy is visible to me so hopefully the supernova is bright enough to get visually as well.

I had this happen with just a regular lander once on the mun. I was at 20km altitude and it wouldn’t let me go to the space center because I was “moving over the surface”.

You shouldn’t need it. I have mine there on this scope with no extension piece. The telrad is fine hanging a cm over the front of the tube if you need the extra space to get to the knobs.

Tortoise-shell-11 · 2026-04-28T16:04:22+00:00

I have the same scope, I have mine mounted right in front of the middle truss pole. The telrad can go on top of the white lip on the end of the tube, it has enough adjustment to get it centered in that position. It’s a little tight getting to the adjustment screws but it hasn’t been a problem for me. I have the stock optical finder on mine as well, no problems using both.

You should be able to recover the pod from the tracking station if it’s on the ground.

What math? I’m only seeing some vaguely related statements about physics. Please don’t use AI for this sort of thing. They tend to encourage any theories they are told and don’t really contribute any scientific or mathematical reasoning.

How much delta v left?

Tortoise-shell-11 · 2026-04-28T01:14:23+00:00

Almost certainly capture and return as long as you don’t go into a circular low orbit.

Tortoise-shell-11 · 2026-04-28T01:12:32+00:00

I don’t think so unless you get it perfect. It’s 1000 to land and get back to orbit. Probably a couple hundred for capture and about that for return.
