To Mars and back in 78 days, neat.
Too bad Mars does not have much atmosphere. It’s kind of wasteful to have to spend half the voyage braking if there were some other way to achieve the deceleration needed at the end.
The very high speed could spell trouble for the craft if encountering a bit of asteroid or comet dust. I’d want to send the first few to Mars unmanned to make sure it could be safely done.

The short answer is no. It can't be done safely.

Too bad Mars does not have much atmosphere. Yes too bad that NASA has determined that Mars consists of rocks and dirt. You would think that looking at rocks and dirt could be accomplished by going to any number of places on this planet, and yet taxpayer money keeps getting squandered on sending stuff to mars.
