# § 18321. Human space flight beyond low-Earth orbit

**(a)** **Findings** Congress makes the following findings:

**(1)** The extension of the human presence from low-Earth orbit to other regions of space beyond low-Earth orbit will enable missions to the surface of the Moon and missions to deep space destinations such as near-Earth asteroids and Mars.

**(2)** The regions of cis-lunar space are accessible to other national and commercial launch capabilities, and such access raises a host of national security concerns and economic implications that international human space endeavors can help to address.

**(3)** The ability to support human missions in regions beyond low-Earth orbit and on the surface of the Moon can also drive developments in emerging areas of space infrastructure and technology.

**(4)** Developments in space infrastructure and technology can stimulate and enable increased space applications, such as in-space servicing, propellant resupply and transfer, and in situ resource utilization, and open opportunities for additional users of space, whether national, commercial, or international.

**(5)** A long term objective for human exploration of space should be the eventual international exploration of Mars.

**(6)** Future international missions beyond low-Earth orbit should be designed to incorporate capability development and availability, affordability, and international contributions.

**(7)** Human space flight and future exploration beyond low-Earth orbit should be based around a pay-as-you-go approach. Requirements in new launch and crew systems authorized in this chapter should be scaled to the minimum necessary to meet the core national mission capability needed to conduct cis-lunar missions. These initial missions, along with the development of new technologies and in-space capabilities can form the foundation for missions to other destinations. These initial missions also should provide operational experience prior to the further human expansion into space.

**(b)** **Report on international collaboration**

**(1)** **Report required** Not later than 120 days after October 11, 2010, the Administrator shall submit to the appropriate committees of Congress a report on the following assets and capabilities:

**(A)** Any effort by NASA to expand and ensure effective international collaboration on the ISS.

**(B)** The efforts of NASA, including its approach and progress, in defining near-term, cis-lunar space human missions.

**(2)** **NASA contributions** In preparing the report required by paragraph (1), the Administrator shall assume that NASA will contribute to the efforts described in that paragraph the following:

**(A)** A Space Launch System.

**(B)** A multi-purpose crew vehicle.

**(C)** Such other technology elements the Administrator may consider appropriate, and which the Administrator shall specifically identify in the report.
