美国宇航局前宇航员、双胞胎兄弟马克·凯利和斯科特·凯利各自执行过四次太空任务，并参与了美国宇航局的双胞胎研究项目，旨在探索太空飞行对人体的影响。
在周四SpaceX发射前数小时，他们接受了《CBS晨间秀》的采访，谈及美国宇航局预算削减、驻守国际空间站的挑战以及太空飞行任务。
作为总统削减开支计划的一部分，美国国家航空航天局（NASA）将裁减20%的员工。亚利桑那州民主党参议员马克·凯利表示，他一直在与交通部长肖恩·达菲就NASA的未来发展路径进行磋商。
达菲目前还担任美国国家航空航天局（NASA）的临时局长。此前，白宫于本月早些时候撤销了对亿万富翁企业家贾里德·艾萨克曼的提名，而艾萨克曼曾得到埃隆·马斯克的支持。
这位参议员表示：“我们始终希望留住最优秀的人才。这对政府各部门乃至私营企业的任何项目都至关重要。项目和机构往往需要经历变革。我认为当下正是变革之时，但美国国家航空航天局（NASA）是一个具有韧性和创新精神的机构。”
明年，“阿尔忒弥斯2号”任务计划将宇航员送往月球轨道。
SpaceX载人龙飞船飞行任务
美国国家航空航天局（NASA）将于美国东部时间周四中午12:09左右，通过SpaceX的载人龙飞船向国际空间站发射新一批宇航员。这一发射时间点大致是地球自转将猎鹰9号火箭推至与空间站轨道对齐的时刻。该机组包括三名宇航员，他们是在去年NASA遭遇波音公司问题频出的星际线飞船项目后，被调配执行此次飞行任务的。
周四搭乘SpaceX飞船的迈克尔·芬克上校，曾是马克·凯利的宇航员同事。
马克·凯利表示：“迈克、我弟弟和我，我们曾经都是同学。1996年进入了美国宇航局（NASA）。”
芬克（Fincke）与马克·凯利（Mark Kelly）均参与了航天飞机"奋进号"的最后一次飞行任务。
马克·凯利表示：“时隔14年，这是他再度重返太空。我必须到场支持他和他的家人，亲眼见证他再一次飞向空间站。”
他笑着承认自己有些嫉妒，说道："你在约8分钟内从静止加速到每小时17500英里，然后与轨道上这座不可思议的空间站对接。这种体验无与伦比。"
目前尚未确定SpaceX载人龙飞船乘组的返回日期。
斯科特·凯利表示，在国际空间站最具挑战性的部分是与"地球所能提供的一切"相隔绝。
他说：“地球是一颗神奇的星球，但你却与恶劣的天气隔绝，与家人分离，与你所珍视的一切相隔。”

Twin brothers and former NASA astronauts Mark and Scott Kelly have each flown four missions and were part of NASA's twin study to research the impact of spaceflight on the human body.
Hours before Thursday's SpaceX launch , they spoke to "CBS Mornings" about NASA cuts, the challenges of being at the International Space Station and the spaceflight.
NASA is set to lose 20% of its workforce as part of the president's efforts to cut spending. Sen. Mark Kelly, a Democratic lawmaker from Arizona, said he's been working with Transportation Secretary Sean Duffy about the path forward for NASA.
Duffy is also serving as the temporary NASA administrator after the White House pulled the nomination earlier this month for billionaire entrepreneur Jared Isaacman, who was backed by Elon Musk.
"We always want to retain the best people. That's critical to any program across government, but also in the private sector," the senator said. "Often projects and programs and agencies have to undergo some change. I think this is a time with some change right now, but NASA is a resilient and innovative agency."
Next year, the Artemis II mission is scheduled to take astronauts around the moon.
SpaceX Crew Dragon flight
NASA is launching a fresh crew to the International Space Station around 12:09 p.m. ET Thursday aboard a SpaceX Crew Dragon capsule. That time is roughly the moment Earth's rotation carries the Falcon 9 rocket into alignment with the space station's orbit. The crew includes three fliers who were assigned to the flight after NASA ran into issues with Boeing's troubled Starliner capsule last year.
Aboard Thursday's SpaceX flight is Col. Michael Fincke, a former crewmate of Mark Kelly.
"Mike and my brother and I, we were all classmates. Got to NASA in 1996," Mark Kelly said.
Fincke and Mark Kelly were both on the space shuttle Endeavour's final mission.
"Now this is the next time he's going back into space 14 years later. So I just had to be here, to be here for him and his family and watch him launch up to the space station just one more time," Mark Kelly said.
He admitted laughingly that he is a little jealous, saying, "you go from zero to 17,500 miles per hour in about 8 minutes and then dock with this incredible space station on orbit. It is an experience like none other."
There is currently no date scheduled for the SpaceX Dragon Crew to return.
Scott Kelly said the most challenging part of being at the ISS is being separated "from everything that Earth has to offer."
"Earth's an amazing planet and you are separated from the weather, you are separated from your family. You are separated from all these things that you hold dear," he said.
