SpaceX put another bird in the air this week. Now the slate is clean for the Falcon Heavy to make its debut on the pad February 6. I am hopeful that the flight is a total success but I am also not going to get my hopes up. Multicore rockets are very hard and this one will most likely have a partial failure. If things go right, great. If they go wrong, SpaceX will learn from it and get back to flying. That, in my book, is the only way to go.
