    Good article for pointing out that specific rocket math. The optimistic tone of that article, though, is very much a product of its publication date of February 2020. The space programs have suffered major technical, financial, and political setbacks since then, and the geopolitical moment doesn't really lend itself to megaprojects like moon missions.
