Subcommittee: International Collaboration and Competition in Space: Oversight of NASA’s Role and Programs

WASHINGTON, D.C. — U.S. Senator John Hickenlooper (D-CO), Chair of the Subcommittee on Space and Science, will convene a subcommittee hearing titled “International Collaboration and Competition in Space:  Oversight of NASA’s Role and Programs” at 10:00 a.m. EDT on Thursday, October 21, 2021. The United States has long been the global leader in space exploration and has benefitted from robust, peaceful international collaboration. This hearing will examine required actions, particularly at the National Aeronautics and Space Administration (NASA), to promote U.S. civil and commercial space sector competitiveness, attract and maintain strong global partnerships, and preserve U.S. space leadership in the wake of rising international competition. Topics such as International Space Station extension, commercial low-Earth orbit (LEO) development, and requirements to execute NASA’s Artemis program, to include needed updates to authorizing legislation, will be considered.
