If I'm correct, 2,5m ASAS does not include reaction wheels, thus it is lighter than 1,25m one. Edit: whoops, I'm sorry.. Just checked ingame. i think it was changed in 0.21.1 and it includes reaction wheels now... (hmm...)
and the words "Ne'er looked back, never feared, never cried" reminds me of a Jebediah Kerman who strapped himself to a rocket and launched for the sun with a huge grin on his face
