space-stationAccord­ing to NASA the ear­li­est the space shut­tle will be able to launch will be March 17, at 7:45 pm. This mis­sion is sched­uled to car­ry the first Puer­to Rican Astro­naut into space and the Inter­na­tion­al space sta­tion.  This mis­sion was delayed last month due to leaky valves in the engine area (which pro­vide the shut­tle hydro­gen fuel) to keep them pres­sur­ized prop­er­ly.
