Could the Voyager spacecraft be spin-stabilized to keep their high gain antennas pointing towards the Sun (and therefore Earth)?

A suggestion has been made that the Voyagers may run out of propellant and so may not be able to maintain pointing near the Earth for communications. According to @BowlOfRed's answer: Although the ...

Flat-spin transition manoeuvre: why is the angular momentum not constant?

In an article by Rahn and Barba, in which a flat-spin transition manoeuvre is investigated, the following figure is presented: I'm trying to reproduce this figure by integrating the following coupled ...

Change a Spacecraft's attitude from 3 - axis stabilised to spin stabilised?

I am essentially trying to "spin up" a s/c, so it spins about 1 axis at a known spin - rate. I then need to figure out how much time it will take to do that, and how much force required (which I ...

How did the upper stage of the Juno 1 rocket change its orientation while it was spinning?

The upper stage of the Juno 1 rocket was spun up to a high speed prior to launch so it would be spin stabilized and not require a guidance system. After the upper stage separated from the 1st stage it ...

Has adjustable Yo-Yo de-spin been tested or demonstrated?

The video in the interesting question How did the GoFast 2014 Rocket de-spin? shows a de-spin that went well. An initial very fast spin (for stabilization during propulsion) is almost perfectly de-...

Why doesn't the ISS start to spin if people walk inside?

I have read that prior to launch all people and tools are fastened down to prevent a rocket from losing the balance. Why doesn't the ISS begin to spin as astronauts are walking inside of it? Or is ...

Why does spinning help stabilisation?

I don't really understand why do we use spin stabilisation for rocket launches? If I understand correctly, the idea is to make the rocket spin really fast so that any asymmetry in the thrust/...
