You should plead the 5th on that issue since the Constitution says nothing about space exploration.
Otherwise, there is an aspect of fraud with repect to how the corrupt feds have sold NASA to taxpayers. That needs to be addressed imo.
After all, the Founding States gave the power of the purse to the House (1.7.1), ordinary voters having constitutional authority to elect representatives from the time that the Constitution was ratified.
NASA minimally has to go under the electron microscope with respect to NASA possibly paying $600 for things like a toilet seat that military contractors, for example, are alleged to have charged the feds; no accountability.
NASA has also been helping to unconstitutionally expand the federal governments constitutionally limited powers as evidenced by its involvement in climate change politics, the feds having no constitutional authority to regulate, tax and spend for such an issue.
On the other hand, if NASAs functions have a constitutionally justifiable place in the federal government, Im sure that Trump will find it, even if the Constitution needs to be amended.
You fail to explain the Louisiana purchase and Lewis and Clark expedition. Authorized by one of the authors of the constitution.
