In a 50-49 vote along party lines, the Senate approved President Trump's pick to lead NASA — Oklahoma Congressman and Navy Reserve pilot, James Bridenstine.
Why it matters: The confirmation comes amid concern "about his record of partisanship as well as some statements questioning climate change, an area of research in which the space agency plays a central role," per the New York Times. The confirmation wraps up a seven and a half month period that left NASA without a permanent leader.
