> In all three cases it can be argued that these studies make sense. It also can be argued that the Biden administration is putting pressure on these agencies to find ways to squelch this new technology, especially because it is central to the development of SpaceX’s Superheavy/Starship rocket, and there is real hostility in Democrat/leftist circles to Elon Musk. This latter argument is further strengthened when you consider the explosive possibilities of hydrogen fuel, used by the space shuttle for decades as well as NASA’s SLS rocket. I can’t imagine its danger is less than methane. If hydrogen has been determined to be okay why should methane now be considered a threat? > Either way, we can be sure of one thing: These studies will slow down development by SpaceX and others of these new methane-fueled rockets. They will also provide ammunition for outside environmental groups who want to file further lawsuits against these companies to stop their rockets from launching.
