I was watching the movie The Martian and I realised afterwards that thanks to its really great CGI, some people think it is based on real story and there are even some who think it was made on Mars.
While both is false, it opens another question: How to prove you actually landed on Mars?
The year is 2025. After your least favorite candidate for POTUS of 2016 had their 2 terms, a cool guy is elected president in 2024. One of his promises is get us to the Mars. For reals.
Thing is, that 2024's blockbuster movie was completely generated by computers. And about 80% of viewers could not tell that the actors are made up. Even though the movie did cost awful lot of money, it opens lot of conspiracy theories.
You are NASA director. The rocket to Mars is fully tested. Astronauts ready. Probability of mission to Mars success: Over 97 percent.
Even though you communicated all the preparation steps openly to the public, everything is communicated through electronical media. Photoshop version released in 2023 is really easy to use and average home computer can make really great CGI.
How to convince the people that you are actually going to get there physically and walk on Mars by 2026?
