    So we all know the story here. Composite fuel tank failed and yet NASA refused the X33 be built with aluminium tanks and so it got scrapped. That was 2001. Northrop then solved the fuel tank issue in 2004.

    The question is though. It is now 17 years later and a lot of the technology required for the X33 to work is now in place. I don’t think it would cost much to build an X33 and have the whole Venture Star concept tested.

    The whole thing pisses me off. The X33 was basically built and then scrapped by the Bush administration. Rocketdyne built the RS2200 linear aero spike engines. Probably the most advanced rocket engines ever built. 17 years later and the technology has never been used.

    Yet we have billions being spent on SLS which is nothing more than reassembled Space Shuttle technology which is already basically obsolete.

    A 2 pronged approach is required. Low cost to LEO can be achieved in 2 ways. SSTO or Landing cores and reusing them. SpaceX has already shown that reusing cores works. They’ve also shown that they can build dependable launch system. Congress needs to scrap SLS and properly fund the BFR. Private industry will get it done cheaper.

    A new drive to produce a SSTO scale model should then be launched. Use the X33 as a basis and apply new technologies learned over the last 17 years. Huge advances have been made in composite materials which could make SSTO even more viable.

    Is all this just a silly suggestion. Are there any SLS supporters here who actually think this is the way forward?

    True AM, or it was "scrapped" officially and the tech ended up in black military hands. I'd be very surprised if such proven technology that cost a pretty penny wasn't being used.

    Rejoice in the awareness of feeling stupid, for that’s how you end up learning new things. If you’re not aware you’re stupid, you probably are.

    True. No doubt elements of the X33 was used for instance on the X37. Very frustrating to see the first real attempt at a SSTO vehicle not being even tested though.

    And the engines not being used. What a waste.
