In times orbit where they would be met by an Ares past, specific objectives determined the 1-launched Orion and its crew. Once again, a specification of the hardware; today that goal-orientated programme. clarity of foresight is missing and this factor is By 2009 the Constellation programme was beginning to take its toll on decision-makers clearly unaffordable and a lengthy analysis by and managers alike. an independent review committee concluded 84 Spaceflight Vol 58 March 2016 84-88.indd 84 1/28/2016 12:24:38 PM EXPLORATION The resulting decision, following an appeal for anyone to give him an answer, was for President Kennedy to tear-up NASA’s existing von Braun paradigm – sequential development of space stations/Moon missions/Mars landings – and head straight for the lunar surface with intrepid astronauts. It got the job done, raising the prestige of the President, restoring US honour and increasing its standing in a world rocked by ideological division. Redefinition More than 40 years on, as conceived Orion was defined as a Crew Exploration Vehicle for carrying astronauts to low Earth orbit, supplying the ISS and for deep-space flights, envisaged as a spacecraft capable of carrying out three functional roles. When Orion was resurrected as a deep-space exploration vehicle in 2011 it gathered up those roles into a single specification and its name morphed into the Multi-Purpose Crew Vehicle (MPCV) before regaining its original title when the spacecraft The Orion Crew Module and its ESM displays the aft propulsion elements which will manage orbital, survived the night of the long knives.
