Here's what to watch out for this week:

• Monday: President Trump holds a Space Policy Directive signing ceremony.
• Tuesday: Polls are open in Alabama's special election, 8 a.m. to 8 p.m. ET. ... Trump signs the National Defense Authorization Act for FY 2018.
• Wednesday: Tax conference committee public hearing. This isn't where the actual decisions will be made — look for mostly just statements. But if there are major issues Republicans haven't solved by this point, this is where they could spill out into the open.
• Thursday: The FCC votes on whether to repeal net neutrality rules. A repeal could allow internet providers to block or slow down content, or charge more for content like streaming video.
• Friday: Last day of open enrollment for Affordable Care Act coverage for 2018. Spoiler alert: It's likely to be way down from last year.
