Polstar

I tried one on a solar probe but the burn time was 18hrs to create a circular orbit. Gave up and not used them since. I am thinking of building an interplanetary ship with 4 or 8 engines but from what I've read I'll stick with nuclear.

So far none stranded but many catastrophic launch failures (revert to vehicle assembly ftw!). Currently have two kerbals on my space station but they can be recovered easily.

Proudest moment was the first stable rocket launch that didn't wobble or spin out of control then explode! Also first space station docking, duna rover, Mun landings all of which are routine.

My first rockets were called Hermii 1 to 14 for narrow bodied manned flights. Unmanned probes were called Sunarii 1 & 2 and the large body manned version is known as Hermii II flight 1 etc.
