Five agreements were signed between January 2007 and June 2007: The three initiatives of the Space Act Agreement, COTS, CSTC and CCDev are for the development, construction and experimentation of design concepts, but CSEC is different from the other two initiatives that do not provide funding. CSTC agreements are merely instruments that require NASA to strengthen cooperation and provide information and other entities to private sector companies, but this obligation has no financial impact and both parties (nasa and private companies) should themselves guarantee the necessary resources to their respective parts of their activities.  In addition to these two initiatives, NASA has entered into five other agreements under the Commercial Space Transportation Capabilities (CSTC). [unverified in body] Four of the cooperation agreements signed in 2010 have a maximum period of three years. In the fifth, SpaceDev, the period is censored.  So far, NASA has released a list of progress points achieved only for SpaceDev and the same Dream Chaser space probe is also one of the winners (albeit with different stages) of the CCDev 1 and 2 cycles.  The Agency concludes its agreements with various partners to support the objectives of the NASA mission and the program, including international cooperative space activities.  Such agreements have been concluded for Orbital Commercial Transport Services (COTS) and Commercial Crew Development (CCDev). They are not subject to normal federal acquisition rules.  Open Space Agreements (ASAs) are a kind of legal agreement established by the National Aeronautics and Space Act of 1958 (and subsequent congressional authorizations) that clearly authorizes NASA to cooperate with any entity authorizing the execution of the government`s mandate.
