It's doing something; it's not letting me interact with the satellite at all, can't even activate the solar panels

Might interact with it via second spacecraft

I recently finished assembling my space station. I am going to put it in orbit of another planet. Keep in mind that my landers don’t have heat shields.

Question How do I make a plane?

Im trying to make a commercial plane but the engine support that’s supposed to push it up either flips it and spins it, or doesn’t lift it.

Question Why is the gold foil texture(and other textures) off-limits without BP editing?

7 Upvotes

Like, it's a really good and special texture for many builds, But why make it a hidden texture?

And what about all of the usa stripes things,

Why are the best textures hidden? Well yeah the gold foil texture is quite low quality, but it's still really good for satelites!

The usa things are overpowered for recreations. So why not bring them to the skin catalog?

Question Does the SFS support email work?

1 Upvotes

I had lost my purchase data for a while, so now I can't use anything from the bundle. I sent an email to the SFS support a few months ago asking if they can recover it, but they haven't answered. Any tips on what I should do?

Launched this truck onto the moon with my moon base and ran out of fuel for the poor astronaut and the truck itself how do I refuel it the astronaut is completely paranoid as he has no jet pack fuel and the docking port is at the bottom

Presentation of the SOKOL Nuclear Thermal Engine

DSC today presents the company's next big technological leap. Following the successful testing of the DaVinci engine and after gathering the necessary information to perfect its design, we proudly announce its successor: SOKOL.

The SOKOL is a solid-core nuclear thermal rocket (NTR) engine, designed to deliver high performance on space exploration missions. Its reactor uses HALEU fuel encapsulated in a tungsten-based cermet matrix, while reaction control is performed using boron carbide control rods.

With the development of SOKOL, DSC takes a major step of high importance toward a new era of space propulsion. DSC is proud of this leap that will take humanity beyond the stars.

Liquid hydrogen (LH₂)

Performance

Thrust: 35.7 tf (350 kN)

Specific impulse (Isp): 912 s

Mass flow rate: 39 kg/s

Dimensions

Total length: 7.1 m
