President Trump signaled what could become a vigorous return to space exploration by the United States when he reconstituted the National Space Council. Dormant since the end of the George H.W. Bush administration, the council’s chairman, Vice President Mike Pence, and its executive secretary, Dr. Scott Pace, have vowed to build a manned space program to reach the moon and beyond to Mars. As with the two previous boom cycles of aerospace development, in World War II and the Apollo program, one of the main beneficiaries of the aggressive effort will be the U.S. manufacturing sector.
