SPACE.com - WASHINGTON — NASA told U.S. lawmakers Monday (Jan. 10) it intends to build a heavy-lift rocket that incorporates the space shuttle’s main engines, giant external tank and taller versions of the solid-rocket boosters it jettisons on the way to orbit, according to a senior NASA official. But neither the rocket nor the crew vehicle it would launch can be completed within the cost and schedule Congress outlined for the project late last year.
