The form of access-to-space for NASA space missions is often dictated before they are designed. Typically, solicitations specify the form¿i.e., the launch vehicle to be used. The investigator then tries to design a mission within the given form and cost limits. This study adopts a more pragmatic point of view: that the form of access should follow from the function of the mission. Given the function, the form of space access is then optimized. The functions of a broad range of space technology experiments and current forms of space access were analyzed. Results show that there might be a more effective approach to access-to-space. The function of a mission is described by a few parameters related to the operation and success of the mission itself; and is divorced from preconceptions about access-to-space. For example, a mission may require a certain mass, power and orbit location, but not a particular launch vehicle or spacecraft bus. The study examined function parameters from hundreds of space technology experiments, including Air Force satellites, technologies reported at the NSTC 2007 conference and the 2008 Small Sat Conference, past university-class satellites and past and future missions from the NASA's New Millennium Program. Parameters from each of the experiments were catalogued and analyzed. Analysis then identified forms of access-to-space that do (or do not) support present function. Methods for accessing space represent options available to investigators in the form trade space. For form to follow function, the trade space must contain several accessible options.
