I mean, as far as unmanned rockets to mars go, several countries have been doing that every few years for a couple of decades now.
As I said they should try make a mission to get a rocket to Mars in under a month, the mission is not getting to mars it's developing energy that can do that in a month(give or take a few weeks)

Researchers at the University of Washington are working on a fusion-powered spacecraft that could theoretically ferry astronauts to Mars and back in just 30 days—shaving off years from what scientists believe a trip using current technology would take.
The project, funded by NASA's Innovative Advanced Concepts Program and also involving Redmond, Wash.-based space propulsion company MSNW, is exploring a "unique manipulation of nuclear fusion," according to the University of Washington. If the technology works, it could cut down the time it takes for interplanetary voyages while also reducing costs and the health risks faced by humans making such trips,.
