Roll-out Once again learning from the lessons of the past, and again re-inventing the technology that has gone before, Carter and his people at NASA create �Hercules�, a super booster with a five engine core block unit which is capable of being supported by either two or four strap-on elements. Looking like a cross between the first stage of the old Saturn 5 and four solid rocket boosters from the old space shuttle programme the first of Carter�s Hercules Super Boosters is now seen for the first time rolling toward the launch pad on one of the Crawler super heavy transports that are used to move spacecraft from the Vehicle Assembly Building to the launch pad at Kennedy Space Centre. The use of new metals and alloys will mean that the new super booster is both lighter and stronger than anything that has gone before it. Also by using new fuels and fuel formulas a greater fuel efficiency and weight to thrust capacity can be achieved for the new booster. Additionally by using new metals and alloys, and new fuels and furl formulas, the two or four strap-on elements can now be liquid fuelled rather than needing a solid fuel propellant to assist in lifting the booster, and its future payloads off the launch pad.
