Why reusable rockets are important for the future – 8.31


This week we look at why reusable rockets are not just for getting the cost of space flight down, but essential for the future of human colonization of the cosmos.

In Space News we have:
* Space Launch System Design Review Completed
* NASA Provides Daily Views of Earth Online (http://epic.gsfc.nasa.gov)
* Orbital ATK ramps up Booster production for Space Launch System maiden flight
* Snooze your way to Mars

    Reuse in a space program is on the ground. The factories, assembly buildings, launch pads, flight control centers and the people who work there are the reusable parts of any space launch system. The mass and cost of the rockets are about 85% fuel and the machinery and fuel tanks are a trivial expense by comparison. The goal of rocket design is to maximize the mass fraction of payload and fuel and reduce the mass of the tanks and rocket engines. The engines are designed to provide maximum power with minimum weight and to reduce the “inert mass fraction” of the vehicle.
    As for the cost of launching a payload into orbit, consider that Copenhagen Suborbitals raised $10K to launch their Nex0-1 rocket to 20 miles and the Moon Spike project seeks $1 Million to send a thumb drive to the moon. I think that is a pretty good indication of the cost of space flight. One million dollars to orbit a microsat is probably a minimum.

    I would like to see a comparison of the available pumping mechanisms. Turbopump vs piston pump vs electric pump (Electron) etc. Where do I contact the TMRO team?
