In a surprising display of timeliness, the U.S. Senate and House of Representatives have both now released their funding bills for NASA in fiscal year 2019. The two bills are broadly consistent in their repudiation of cuts and reorganizations of major NASA programs, support for the Administration's lunar ambitions, and generous top lines for NASA's budget.

However, there are significant differences, and those differences will be the point of negotiations that will now begin between the two committees. It is very likely that there will be no votes on a final bill until November or December, after the election.

Below is a table comparing proposed funding levels of some programs and directorates between last year's final budget, the President's Budget Request, and the House and Senate bills.
