The post is mostly about how awesome NASA is, which is fair. Nonetheless, you can skip following the link after reading the below, quoted directly from

  • The construction of the Death Star has been estimated to cost more than $850,000,000,000,000,000. We’re working hard to reduce the deficit, not expand it.
  • The Administration does not support blowing up planets.
  • Why would we spend countless taxpayer dollars on a Death Star with a fundamental flaw that can be exploited by a one-man starship?

To be fair to the petitioners, I am sure they were more interested in a Death Star II.
