The budget to be proposed for NASA later today will offer some preliminary support for a lunar exploration program, but has no specific timelines for when humans might return to the surface of the Moon—nor funding to make such an ambitious undertaking happen.

The White House will release its fiscal year 2019 budget for the space agency at 1pm ET today, and although Congress sets the budget for the United States, this document offers a good overview of the Trump administration’s plans for NASA. Ars reviewed a copy of the budget documents to be released today.

The FY 2019 budget provides a top-line number of $19.892 billion for NASA, an increase over the FY 2018 budget of $19.519 billion that is largely attributable to the recent budget agreement passed by Congress, which raises spending levels for defense and discretionary spending.
