The US President Barack Obama will scrap the rockets currently being developed by the US space agency to replace the shuttle and go back to the Moon. It is anticipated that NASA chief Charlie Bolden will outline the new vision to coincide with Mr Obama's 2011 budget request to Congress.Pre-announcement briefings have trailed the likelihood of the agency getting a 6 billion dollar increase in its funding over the next five years. Some of this money will be used by NASA to incentivise private companies to help them bring forward a new generation of launchers to carry humans into orbit.The changes, if confirmed, fit broadly with ideas put forward by a special panel convened last year by Mr Obama to review U.S human spaceflight options.The agency has been working to produce two new rockets known as Ares-1 and -5 – and a new crewship called Orion. These are intended to replace the shuttle but have the capability also to take astronauts back to the Moon by 2020.
