The Senate Commerce, Science, and Transportation Committee will markup a new NASA authorization bill on Wednesday that focuses on the desire to avoid disruption to NASA’s human spaceflight program during the upcoming presidential transition. It is one of several bills the committee will deal with that day, including the INSPIRE Women Act that passed the House earlier this year. It is designed to encourage women to study science, technology, engineering and mathematics (STEM).

The 2016 NASA Transition Authorization Act, S. 3346, is co-sponsored by three Republicans and three Democrats: Sen. Ted Cruz (R-Texas) and Sen. Gary Peters (D-Michigan), the chair and ranking member of the Subcommittee on Space, Science, and Competitiveness; Florida’s two Senators, Bill Nelson (D), who is the ranking member of the full committee, and Marco Rubio (R); Sen. Roger Wicker (R-Mississippi); and Sen. Tom Udall (D-New Mexico). Udall and Rubio both are subcommittee members; Wicker is on the full committee.

The 73-page bill incorporates changes to a draft that was circulated earlier, but the main themes remain the same. Among the provisions are the following (quotes are from the committee’s press release or the bill itself):

affirms support for continuity across presidential administrations in space science and exploration, noting progress on development of the Space Launch System (SLS) and Orion programs for deep space human exploration, on the James Webb Space Telescope (JWST), and on commercial crew systems;

affirms that “NASA is and should remain a multi-mission agency with a balanced and robust set of core missions in science, space technology, aeronautics, human space flight and exploration, and education”;

supports utilization of the International Space Station through at least 2024 and requires an evaluation of the feasibility of operations through at least 2028, while also requiring a report from NASA on how to transform low Earth orbit from a “model reliant on government support to one reflecting a more commercially viable future”;

adds human exploration of Mars as an explicit goal and objective for NASA and requires NASA to submit a “strategic framework and critical decision plan” on how to achieve it;

directs NASA to continue the SLS and Orion programs with the first uncrewed mission in 2018 and the first mission with a crew “by 2021”;

requires a report from NASA evaluating alternatives to the Asteroid Redirect Robotic Mission for demonstrating technologies and capabilities needed for human trips to Mars;

asserts that it is U.S. policy to develop technologies to support NASA’s core missions, including propulsion technologies to reduce the human travel time to Mars;

expresses support for several space science missions, including JWST, its successor the Wide Field Infrared Space Telescope (WFIRST), the Mars 2020 rover, and a mission to Europa (the bill is silent on Earth science);

allows NASA to provide medical monitoring, diagnosis and treatment for current U.S. government astronauts and former astronauts and payload specialists for “psychological and medical conditions deemed by NASA to be associated with human spaceflight”; and

directs NASA to take steps to improve oversight of information technology and cybersecurity.

The bill authorizes $19.508 billion for NASA in FY2017, the same amount approved by the House Appropriations Committee in its version of the FY2017 Commerce-Justice-Science appropriations bill. That bill has not been considered by the House yet. The amount is $202 million more than the Senate Appropriations Committee approved. The authorization bill allocates the difference to NASA’s exploration account (which funds SLS and Orion). Otherwise, the authorized amounts are the same as in the Senate Appropriations committee-approved bill. The Senate bill was brought to the floor for debate in June, but was derailed by the gun control debate.

Authorization bills set policy and recommend funding levels; they do not actually provide any money. Only appropriations bills provide money to agencies like NASA.

The House passed a NASA authorization bill in 2015 (H.R. 810) that can serve as a basis for compromise if both chambers want to pass a bill this year, even though time is short. Rep. Brian Babin (R-Texas), chair of the Space Subcommittee of the House Science, Space, and Technology Committee, has called on the Senate to pass a bill several times, most recently last week.

The other space-related bill scheduled for markup on Wednesday is the Inspiring Next Space Pioneers, Innovators, Researchers, and Explorers (INSPIRE) Women Act, H.R. 4755. The House passed the bill in March. The bill was sponsored by Rep. Barbara Comstock (R-Virginia). There were no hearings or markups of the bill; it was introduced and went directly to the floor. No funding is included in the bill. It simply directs NASA to take steps to encourage women to study STEM fields and submit a plan on how NASA can facilitate and support current and retired astronauts, scientists, engineers and innovators to engage with K-12 female STEM students.
