; and (2) alternative missions may provide a more cost effective and scientifically beneficial means to demonstrate the technologies needed for a human mission to Mars that would otherwise be demonstrated by the Asteroid Robotic Redirect Mission. (c) Evaluation and report Not later than 180 days after the date of enactment of this Act, the Administrator shall— (1) conduct an evaluation of— (A) alternative approaches to the Asteroid Robotic Redirect Mission for demonstrating the technologies and capabilities needed for a human mission to Mars that would otherwise be demonstrated by the Asteroid Robotic Redirect Mission; (B) the scientific and technical benefits of the alternative approaches under subparagraph (A) to future human space exploration compared to scientific and technical benefits of the Asteroid Redirect Robotic Mission; (C) the commercial benefits of the alternative approaches identified in subparagraph (A), including the impact on the development of domestic solar electric propulsion technology to bolster United States competitiveness in the global marketplace; and (D) a comparison of the estimated costs of the alternative approaches identified in subparagraph (A); and (2) submit to the appropriate committees of Congress a report on the evaluation under paragraph (1), including any recommendations. 435. Mars 2033 report (a) In general Not later than 120 days after the date of enactment of this Act, the Administrator shall contract with an independent, non-governmental systems engineering and technical assistance organization to study a Mars human space flight mission to be launched in 2033. (b) Contents The study shall include— (1) a technical development, test, fielding, and operations plan using the Space Launch System, Orion, and other systems to successfully launch such a Mars human space flight mission by 2033; (2) an annual budget profile, including cost estimates, for the technical development, test, fielding, and operations plan to carry out a Mars human space flight mission by 2033
