Dear Chairman Shelby and Ranking Member Mikulski:
Exploring deep space is vital to inspiring our future innovators and stimulating our economy through technological innovation and development. NASA's Orion spacecraft and Space Launch System (SLS) are building the capability needed to extend human existence throughout deep space. These unparalleled space exploration systems will enable humans to travel farther into the solar system than ever before, spawn new scientific advancements, and result in unprecedented scientific discoveries about our universe.
NASA's space exploration journey continues, building upon the success of Orion's first flight test that launched from Florida in December 2014. Orion, the SLS rocket, and launch operation systems are already being built, tested, and integrated for Exploration Mission-1 (EM-1) that will launch from NASA's Kennedy Space Center in 2018. EM-1 will be the first integrated flight test of the new SLS that will propel Orion to the far side of the moon on a three-week mission to test out deep-space mission capabilities needed to send humans farther into the solar system than ever before. NASA intends to follow this mission with a crewed deep space exploration mission on SLS and Orion in 2021.
We believe Orion and SLS are the cornerstones of our nation's human space exploration enterprise and a source of national pride. We also recognize the thousands of suppliers across 49 states who are building key components for this important new rocket and spacecraft, including those who travelled to Washington, DC from February 23-24 to advocate for the necessary levels of funding to ensure America remains the world's leader in space exploration.
We respectfully urge your support for providing the appropriations necessary for keeping the first integrated Orion & SLS flight demonstration on track for launch in 2018, and the first crewed flight of Orion & SLS on track for a 2021 launch. The Appropriations Committee has repeatedly worked to ensure that these programs have sufficient funding, and we urge you to continue this commitment in the FY 2017 Commerce-Justice-Science Appropriations bill.
