 An Orion spacecraft could be boosted by non-nuclear means to a safer distance only activating its drive well away from Earth and its satellites.The Lofstrom launch loop or a space elevator hypothetically provide excellent solutions; in the case of the space elevator, existing carbon nanotubes composites, with the possible exception of Colossal carbon tubes, do not yet have sufficient tensile strength.All chemical rocket designs are extremely inefficient and expensive when launching large mass into orbit but could be employed if the result were cost effective.
