委员会主席艾迪·伯妮斯·约翰逊(Eddie Bernice Johnson)表示，特朗普政府需要这样的提速计划要花多少钱，以及如何提供这部分预算支持，尤其是考虑到“它对联邦研发机构的其他预算将造成大幅削减”。

　　Committee chair Rep. Eddie Bernice Johnson said the Trump administration needs to clarify exactly how much the ramped-up timeline will cost and how it plans to pay for it, especially given "the deep cuts it has made to the rest of the federal R&D agencies' budgets."

　　约翰逊在给CNN的一份声明中表示：“我希望美国继续努力，以实现让宇航员登上火星这一具有挑战性和鼓舞人心的目标，如果月球是必不可少的中间环，那么我也将支持前往火星。”但他同时表示，“然而，我不准备为了一个武断的截止日期而调拨NASA的其他项目，强迫其冒不必要的风险，或制定目光短浅的计划。”

　　"I would like America to continue to strive to achieve the challenging and inspiring goal of landing astronauts on Mars, and if the Moon is an essential interim step, then I would support going there too," Johnson said in a statement to CNN. "However, I am not prepared to cannibalize the rest of NASA's program or force the agency into taking foolhardy risks or making short-sighted plans simply to meet an arbitrary deadline."

　　大约三周前，NASA向国会提交了一份预算申请，但布里登斯廷表示，他将在4月15日之前提出一份最新的申请，以反映加速后的计划。

　　NASA submitted a budget request to Congress about three weeks ago, but Bridenstine said he would make an updated request, reflecting the accelerated timeline, by April 15.
