From the I'm bored today file:

Titan 3 E

stage 0. 2 solid boosters 10' diameter, eyeballed at about 75' tall. Volume = 6800 cubic feet = 50k gallons each.

stage 1: 240k pounds of hydrazine and nitrogen tetraoxide. Mix ratio 1:1 (by molecules) = 102: 32 by mass. = 180k pounds of nto, 60k pounds of hydrazine. = 82k kg and 27k kg = 59k liters and 27k liters = 86 k total liters = 23k gallons.

stage 2: 55k pounds of hydrazine and nto. = 5.3k gallons.

stage 3: ~10k kg of hydrogen and oxygen. 5:1 molecular ratio (hydrogen rockets run fuel rich) 10:16 mass ratio: 3.5 tons hydrogen, 6 tons oxygen. 13k gallons and 1200 gallons

= 162k gallons if I've done all my math right.

V2 is 11.5 billion miles away which gives 68,000 MPG and counting.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?
--Zachris Topelius

Training a telescope on one’s own belly button will only reveal lint. You like that? You go right on staring at it. I prefer looking at galaxies.
