T+74: Stagnation and Opportunity
NASA Acting Administrator Robert Lightfoot appeared in front of the space subcommittee of the House Science Committee to discuss the 2019 NASA budget request, and I’ve got some thoughts on their decisions regarding the SLS Mobile Launcher and how it affects SLS’ flight rate. And then I get off onto a train of thought regarding the stagnation of and opportunity within the policy gridlock we’re stuck in today.

T+71: Commercial Crew, Congress, and the GAO
The Commercial Crew program—NASA, SpaceX, Boeing, and more—went in front of Congress to discuss the current status of the crew launch systems in development. Concurrently, the GAO released a report warning that more delays are likely, and could put NASA in a tough spot. I share some thoughts on the matter and talk through what is likely to happen this year.

T+70: Polar Launches from Cape Canaveral
The US Air Force has developed a viable corridor for launching to polar and other high-inclination orbits from Cape Canaveral. I spend some time thinking through who may be interested in using that corridor and what its existence could mean for the newer launch vehicles in development.
