I am a huge astrophysics/astronomy nerd and yeah, there's zero chance we are going to Mars anytime soon.
Mars is very uninhabitable. Before we even send people there, there needs to be somewhere for them to stay with food. Food will need to be grown and water recycled because the trip is so damn far. Water recycling is no big deal but growing food is going to be difficult. The habitat has to have room for the food growing (more room than you think) and it also has to have the resources in it to do so (light, dirt, more water for the plants, etc). This is needed because it's a one-way trip. Mars has enough gravity where the amount of fuel needed for a return trip is a lot and returning just isn't feasible.
The worst part is that if one little thing goes wrong, the whole damn colony dies.
Sending rovers to Mars is way more boring but honestly the only way we will ever explore it anytime soon. I'd be very surprised if we have humans on Mars within the next 100 years.
